[dpdk-dev] [RFC 0/7] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: eal: interrupt handle API prototypes
This patch provides prototypes of all the new get set APIs, and
also rearranges the headers related to interrupt framework. Epoll
related definitions prototypes are moved into a new header i.e.
rte_epoll.h and APIs defined in rte_eal_interrupts.h which were
driver specific are moved to rte_interrupts.h (as anyways it was
accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 2: eal/interrupts: implement get set APIs
Implementing all get, set and alloc APIs. Alloc APIs are implemented
to allocate memory for interrupt handle instance. Currently most of
the drivers defines interrupt handle instance as static but now it cant
be static as size of rte_intr_handle is unknown to all the drivers.
Drivers are expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.

Patch 3: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 4: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 5: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 6: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 7: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

[dpdk-dev] [RFC 1/7] eal: interrupt handle API prototypes

[Harman Kalra]

Defining protypes of get/set APIs for accessing/manipulating
interrupt handle fields.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

[dpdk-dev] [RFC 3/7] eal/interrupts: avoid direct access to interrupt handle

[Harman Kalra]

Making changes to the interrupt framework to use interrupt handle
APIs to get/set any field. Direct access to any of the fields
should be avoided to avoid any ABI breakage in future.

[dpdk-dev] [RFC 5/7] drivers: remove direct access to interrupt handle fields

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [RFC 6/7] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

[dpdk-dev] [PATCH v1 0/7] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: eal: interrupt handle API prototypes
This patch provides prototypes of all the new get set APIs, and
also rearranges the headers related to interrupt framework. Epoll
related definitions prototypes are moved into a new header i.e.
rte_epoll.h and APIs defined in rte_eal_interrupts.h which were
driver specific are moved to rte_interrupts.h (as anyways it was
accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 2: eal/interrupts: implement get set APIs
Implementing all get, set and alloc APIs. Alloc APIs are implemented
to allocate memory for interrupt handle instance. Currently most of
the drivers defines interrupt handle instance as static but now it cant
be static as size of rte_intr_handle is unknown to all the drivers.
Drivers are expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.

Patch 3: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 4: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 5: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 6: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 7: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

[dpdk-dev] [PATCH v1 1/7] eal: interrupt handle API prototypes

[Harman Kalra]

Defining protypes of get/set APIs for accessing/manipulating
interrupt handle fields.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

[dpdk-dev] [PATCH v1 2/7] eal/interrupts: implement get set APIs

[Harman Kalra]

Implementing get set APIs for interrupt handle fields.
To make any change to the interrupt handle fields, one
should make use of these APIs.

[dpdk-dev] [PATCH v1 3/7] eal/interrupts: avoid direct access to interrupt handle

[Harman Kalra]

Making changes to the interrupt framework to use interrupt handle
APIs to get/set any field. Direct access to any of the fields
should be avoided to avoid any ABI breakage in future.

[dpdk-dev] [PATCH v1 5/7] drivers: remove direct access to interrupt handle fields

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [PATCH v1 6/7] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

Re: [dpdk-dev] [PATCH v1 0/7] make rte_intr_handle internal

[Harman Kalra]

Ping...
Kindly review the series. Also would like to request PMD maintainers(who uses interrupt APIs) to validate the series for their respective drivers, 
as many drivers underwent interrupt related changes in patch 5 of the series.

Thanks
Harman

Thanks for taking care of this huge cleanup.
I started looking at it.

Re: [dpdk-dev] [PATCH v1 2/7] eal/interrupts: implement get set APIs

Some global comments.

- Please merge API prototype (from patch 1) and actual implementation
in a single patch.
- rte_intr_handle_ seems a rather long prefix, does it really matter
to have the _handle part?
- what part of this API needs to be exported to applications? Let's
hide as much as we can with __rte_internal.

We can call DPDK allocator in all cases.
That would avoid headaches on why multiprocess does not work in some
rarely tested cases.
Wdyt?

Plus "from_hugepage" is misleading, you could be in --no-huge mode,
rte_zmalloc still works.

We don't need this new accessor.
It leaks the internal representation to the API caller.
If the internal representation is later changed, we would have to
maintain this array thing.

The only user is drivers/raw/ifpga/ifpga_rawdev.c.
This driver can build an array itself, and call
rte_intr_handle_efds_index_get() as much as needed.

rte_intr_handle_vec_list_base leaks an internal representation too.

Afaics with the whole series applied, it is always paired with a
rte_intr_handle_vec_list_alloc or rte_intr_handle_vec_list_free.
rte_intr_handle_vec_list_alloc could do this check itself.
And rte_intr_handle_vec_list_free should already be fine, since it
sets intr_vec to NULL.

Since the purpose of the series is to reduce future ABI breakages,
how about making the second parameter "flags" to have some spare bits?
(If not removing it completely per David's suggestion.)

If rte_intr_handle_instance_alloc() returns a pointer to an array,
this function is useless since the user can simply manipulate a pointer.
If we want to make a distinction between a single struct rte_intr_handle and a
commonly allocated bunch of such (but why?), then they should be represented
by distinct types.

Why it's sometimes ENOMEM and sometimes ENOTSUP when the handle is not
allocated?

See above regarding the "index" parameter. If it can be removed, a better name
for this function would be rte_intr_handle_copy().

How about making this parameter "size_t"?

Should be (-rte_errno) per documentation.
Please check all functions in this file that return an "int" status.

Returning a errno value instead of an FD is very error-prone.
Probably returning (-1) is both safe and convenient?

Seems like this common/cnxk name leaked here by mistake?

Should be negative per documentation and to avoid returning a positive value
that cannot be distinguished from a successful return.
Please also check other functions in this file returning an "int" result
(not status).

This is incorrect if "from_hugepage" is set.

This implementation leaves "intr_handle" in an invalid state
and leaks memory on error paths.

I find this constant more cluttering call sites than helpful.
If a handle is allocated with a calloc-like function, plain 1 reads just fine.

<HK> In mellanox 5 driver interrupt handle instance is freed in destructor 
" mlx5_pmd_interrupt_handler_uninstall()" while DPDK memory allocators
are already cleaned up in "rte_eal_cleanup". Hence I allocated interrupt
instances for such cases from normal heap. There could be other such cases
so I think its ok to keep this support.

Regarding name, I will change " from_hugepage" to "dpdk_allocator".

As per suggestion from Dmitry, I will replace bool arg with a flag variable, to 
support more such configurations in future.

This is surprising.
Why would the mlx5 driver wait to release in a destructor?
It should be done once no interrupt handler is necessary (like when
stopping all ports), and that would be before rte_eal_cleanup().

<HK> User wont be able to manipulate the pointer as he is not aware of size of struct rte_intr_handle.
He will observe "dereferencing pointer to incomplete type" compilation error.

<HK> Do you mean, we should have separate APIs for single allocation and batch allocation? As get API
will be useful only in case of batch allocation. Currently interrupt autotests and ifpga_rawdev driver makes
batch allocation. 
I think common API for single and batch is fine, get API is required for returning a particular intr_handle instance.
But one problem I see in current implementation is there should be upper limit check for index in get/set
API, which I will fix.

I don't think we need different APIs, I was asking if it was your intention.
Now I understand it and agree with you.

Maybe index is still not needed: "intr_handle" can just be a pointer to the
right item obtained with rte_intr_handle_instance_index_get(). This way you
also don't need to duplicate the index-checking logic.

In the current implementation, batch allocation of interrupt handle may lead to mem leak while
freeing efds and elist array. I am only freeing efds/elist for intr_handle[0] in rte_intr_handle_instance_free().
To free efds/elist of all the intr_handles[], either I should cache the size parameter passed during alloc. But
where should I store it? In first instance of struct rte_intr_handle. I don't think it will be a good idea.

Since batch allocation is only done in test suite and ifpga_rawdev.c, to keep things simpler let's restrict
rte_intr_handle_instance_alloc() to single instance allocation and user can call this API in a loop and
maintain array of handles locally. 
With this approach get_index API is not required and set_index API can be renamed to rte_intr_handle_copy()

Thoughts? 

Thanks
Harman

<HK> Yes, I will get the reallocated pointer in a tmp variable and will update
(intr_handle[index].elist/efds only after all error paths are cleared.

Now since we are thinking of restricting rte_intr_handle_instance_alloc() to single
intr_handle allocation, I will remove this macro.

[dpdk-dev] [PATCH v2 0/6] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: eal/interrupts: implement get set APIs
This patch provides prototypes and implementation of all the new
get set APIs. Alloc APIs are implemented to allocate memory for
interrupt handle instance. Currently most of the drivers defines
interrupt handle instance as static but now it cant be static as
size of rte_intr_handle is unknown to all the drivers. Drivers are
expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.
This patch also rearranges the headers related to interrupt
framework. Epoll related definitions prototypes are moved into a
new header i.e. rte_epoll.h and APIs defined in rte_eal_interrupts.h
which were driver specific are moved to rte_interrupts.h (as anyways
it was accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 2: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 3: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 4: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 5: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 6: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

[dpdk-dev] [PATCH v2 1/6] eal/interrupts: implement get set APIs

[Harman Kalra]

Prototype/Implement get set APIs for interrupt handle fields.
User wont be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.

[dpdk-dev] [PATCH v2 2/6] eal/interrupts: avoid direct access to interrupt handle

[Harman Kalra]

Making changes to the interrupt framework to use interrupt handle
APIs to get/set any field. Direct access to any of the fields
should be avoided to avoid any ABI breakage in future.

[dpdk-dev] [PATCH v2 4/6] drivers: remove direct access to interrupt handle

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [PATCH v2 5/6] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

I agree rte_intr_handle and eth_devices structure needs to be hidden.
But there does not appear to be an API to check if device supports
receive interrupt mode.

There is:
   RTE_ETH_DEV_INTR_LSC  - link state
   RTE_ETH_DEV_INTR_RMV  - interrupt on removal

but no
   RTE_ETH_DEV_INTR_RXQ  - device supports rxq interrupt

There should be a new flag reported by devices, and the intr_conf should
be checked in rte_eth_dev_configure

Doing this would require fixes many drivers and there is risk of exposing
existing sematic bugs in applications.

Yes, currently "intr_conf.rxq" is checked by respective drivers which supports queue interrupts and enable them if set.
But driver doesn't expose if they are capable of supporting rxq interrupts, just like LSC and RMV.

RTE_ETH_DEV_INTR_RXQ   should be introduces and set by capable drivers in " dev_info.dev_flags" and applications
like l3fwd-power which sets " intr_conf.rxq" should check this flag.

I will add this enhancement to my TODO list and will send it as a new series.

Thanks

I agree with David.
I prefer a simpler API which always use rte_malloc,
and make sure interrupts are always handled between
rte_eal_init and rte_eal_cleanup.
The mlx5 PMD could be reworked to match this requirement.
In any case we should not any memory management in constructors/destructors.

Hi Thomas, David

There are couple of more dependencies on glibc heap APIs:
1. "rte_eal_alarm_init()" allocates an interrupt instance which is used for timerfd, 
is called before "rte_eal_memory_init()" which does the memseg init.
Not sure what all challenges we may face in moving alarm_init after memory_init
as it might break some subsystem inits.
Other option could be to allocate interrupt instance for timerfd on first alarm_setup call. 

2. Currently interrupt handle field inside struct rte_pci_device is static which is changed
to a pointer in this series(as struct rte_intr_handle is hidden inside a c file and size is unknown outside).
I am allocating the memory for this interrupt instance inside "rte_pci_probe_one_driver()" just before
"pci_vfio_map_resource()" which sets up vfio resources and calls " pci_vfio_setup_interrupts()" which setups
the interrupt support. Here challenge is "rte_bus_probe()" also gets called before "rte_eal_memory_init()".

There are many other drivers which statically declares the interrupt handles inside their respective private
structures and memory for those structure was allocated from heap. For such drivers I allocated interrupt instances
also using glibc heap APIs.

Thanks
Harman

Sorry my bad, bus probing happens after "rte_eal_memory_init()", so second point

Could you use rte_malloc in these drivers?

Buffer overrun if "intr_handle->nb_intr < src->nb_intr"?

ENOTSUP usually means the operation is valid from API standpoint

What do you think about having an API to retrieve the entire flags instead?

API are neater when free(NULL) is a no-op.

Please add a similar pair of experimental API for the "handle" member,
it is needed for Windows interrupt support I'm working on top of these series
(IIUC, API changes should be closed by RC1.)
If you will be doing this and don't like "handle" name, it might be like
"dev_handle" or "windows_device".

The macros is not used in the comparison, neither should the log mention it.

Do I understand correctly that these exports are needed
to allow an application to use DPDK callback facilities
for its own interrupt sources?
If so, I'd suggest that instead we export a simpler set of functions:
1. Create/free a handle instance with automatic fixed type selection.
2. Trigger an interrupt on the specified handle instance.
The flow would be that the application listens on whatever it wants,
probably with OS-specific mechanisms, and just notifies the interrupt thread
about events to trigger callbacks.
Because these APIs are experimental we don't need to change it now,
just my thoughts for the future.

How is ABI breakage applicable to internal consumers?

This protects against fields renaming for sure, but convenience is arguable.
If EAL needs to add a EAL-private field to struct rte_intr_handle,
it must add an accessor even though the field is likely OS-specific.
It would be simpler if the definition was in some private EAL header
and could be accessed directly by EAL code.

Regardless of the currently defined flags, we want to have an ABI
ready for future changes, so if there is a "flags" input parameter, it
must be checked against valid values.
You can build a RTE_INTR_ALLOC_KNOWN_FLAGS define that contains all
valid flags either in a private header or only in this .c file if no
other unit needs it.
Next, in this function:

if ((flags & ~RTE_INTR_ALLOC_KNOWN_FLAGS) != 0) {
    rte_errno = EINVAL;
    return NULL;
}

A check in unit tests is then a good thing to add so that developpers
adding new flag get a CI failure.

This is not a blocker as this API is still experimental, but please
let's do this from the start.

If we take the direction of 2 different allocations mode for the interrupts,
I suggest we make it automatic without any API parameter.
We don't have any function to check rte_malloc readiness I think.
But we can detect whether shared memory is ready with this check:
rte_eal_get_configuration()->mem_config->magic == RTE_MAGIC
This check is true at the end of rte_eal_init, so it is false during probing.
Would it be enough? Or should we implement rte_malloc_is_ready()?

Hi Thomas,

It's a very good suggestion. Let's implement "rte_malloc_is_ready()" which could be as
simple as " rte_eal_get_configuration()->mem_config->magic == RTE_MAGIC" check.
There may be more consumers for this API in future.

If we are making it automatic detection, shall we now even have argument to this alloc API?
I added a flags argument (32 bit) in latest series where each bit of this flag can be an allocation capability.
I used two bits for discriminating between glibc malloc and rte_malloc. Shall we keep it or drop it?

David, Dmitry please share your thoughts.

Thanks
Harman

I don't have ideas of how we would extend allocations of such object,
so I am unsure.

In doubt, I would keep this flags field, and validate it's always 0
(as mentioned in my reply on ABI).

You cannot rely on the magic because it is set only after probing.
For such API you need to have another internal flag to check that malloc is setup.

I doubt it should be public. How it is supposed to be used? 
Any application code for DPDK necessarily calls rte_eal_init() first,
after that this function would always return true.

I'd drop it, but no strong opinion.
Since allocation type is automatic and all other properties can be set later,
there are no use cases for any options here.
And if they appear, flags may be insufficient as well.

Yeah, got that. You mean in case of bus probing although rte_malloc is setup
but eal_mcfg_complete() is calledt done yet. So we should set another malloc
specific flag at the end of rte_eal_memory_init(). Correct?

But just for understanding, as David suggested that we preserve keep this flag
then why not use it, have rte_malloc and malloc bits  and make a decision.
Let driver has the flexibility to choose. Do you see any harm in this?

I think the new internal flag should be at the end of rte_eal_malloc_heap_init().
Then a rte_internal function rte_malloc_is_ready() should check this flag.

In V2, I have replaced the bool arg with an 32bit flag in alloc api:
struct rte_intr_handle *rte_intr_instance_alloc(uint32_t flags);

Declared some flags which can be passed by the consumer
/** Interrupt instance allocation flags
 * @see rte_intr_instance_alloc
 */
/** Allocate interrupt instance from traditional heap */
#define RTE_INTR_ALLOC_TRAD_HEAP        0x00000000
/** Allocate interrupt instance using DPDK memory management APIs */
#define RTE_INTR_ALLOC_DPDK_ALLOCATOR   0x00000001

As a future enhancement, if more options to the allocation is required by user,
new flags can be added.

Now since we are planning to remove this flag variable and rely on auto detection mechanism.

I exported only those APIs which are currently used by test suite or example
applications, may be later more APIs can be moved from internal to public on
need basis.

Initially we thought to implement this way only i.e. defining rte_intr_handle inside internal headers
but supporting out of tree drivers was one of the reason to go via this get/set approach. All drivers
internal and external should follow the same way, that was the intention.

What check? I mean that the condition is `max_intr > intr_handle->nb_intr`,
so `RTE_MAX_RXTX_INTR_VEC_ID` is not relevant, `intr_handle->nb_intr` is
dynamic. Probably it should be like this:

	RTE_LOG(ERR, EAL, "Maximum interrupt vector ID (%d) exceeds "
		"the number of available events (%d)\n",
		max_intr, intr_handle->nb_intr);

These API is used as follows. The application has a file descriptor
that becomes readable on some event. The programmer doesn't want to create
another thread like EAL interrupt thread, implement thread-safe callback
registration and invocation. They want to reuse DPDK mechanism instead.
So they create an instance of type EXT and give it the descriptor.
In case of the unit test the descriptor is a pipe read end.
In case of a real application it can be a socket, like in mlx5 PMD.
This is often convenient, but not always. An event may be a signal,
or busy-wait end, or it may be Windows with its completely different IO model
(it's "issue an IO, wait for completion" instead of POSIX
"wait for IO readiness, do a blocking IO").
In all these cases the user needs to create a fake pipe (or whatever)
to fit into how the interrupt thread waits for events.
But what the application really needs is to say "there's an event, please run
the callback on this handle". It's a function call that doesn't require any
explicit file descriptors or handles, doesn't rely on any IO model.
How it is implemented depends on the EAL, for POSIX it will probably be
an internal pipe, Windows can use APC as in eal_intr_thread_schedule().
Again, I'm thinking out loud here, nothing of this needs to be done now.

True for drivers, I understand this, but the question is about EAL itself.
I shouldn't say "internal consumers", I only meant EAL, not inbox drivers.

I like this way of thinking.

[dpdk-dev] [PATCH v3 0/7] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):
https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s

Bg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: malloc: introduce malloc is ready API
This patch introduces a new API which tells if DPDK memory
subsystem is initialized and rte_malloc* APIs are ready to be
used. If rte_malloc* are setup, memory for interrupt instance
is allocated using rte_malloc else using traditional heap APIs.

Patch 2: eal/interrupts: implement get set APIs
This patch provides prototypes and implementation of all the new
get set APIs. Alloc APIs are implemented to allocate memory for
interrupt handle instance. Currently most of the drivers defines
interrupt handle instance as static but now it cant be static as
size of rte_intr_handle is unknown to all the drivers. Drivers are
expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.
This patch also rearranges the headers related to interrupt
framework. Epoll related definitions prototypes are moved into a
new header i.e. rte_epoll.h and APIs defined in rte_eal_interrupts.h
which were driver specific are moved to rte_interrupts.h (as anyways
it was accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 3: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 4: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 5: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 6: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 7: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

[dpdk-dev] [PATCH v3 1/7] malloc: introduce malloc is ready API

[Harman Kalra]

Implementing a new API get the state if DPDK memory management
APIs are initialized.
One of the use case of this API is while allocating an interrupt
instance, if malloc APIs are ready memory for interrupt handles
should be allocated via rte_malloc_* APIs else glibc malloc APIs
are used. Eg. Alarm subsystem is initialised before DPDK memory
infra setup and it allocates an interrupt handle.

[dpdk-dev] [PATCH v3 2/7] eal/interrupts: implement get set APIs

[Harman Kalra]

Prototype/Implement get set APIs for interrupt handle fields.
User won't be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

[dpdk-dev] [PATCH v3 3/7] eal/interrupts: avoid direct access to interrupt handle

[Harman Kalra]

Making changes to the interrupt framework to use interrupt handle
APIs to get/set any field. Direct access to any of the fields
should be avoided to avoid any ABI breakage in future.

[dpdk-dev] [PATCH v3 5/7] drivers: remove direct access to interrupt handle

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [PATCH v3 6/7] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

Truncating copy is error-prone.
It should be either a reallocation (in the future) or an error (now).

This function should accept NULL and be a no-op in such case.

Thanks for adding this API, but please remove the check.
It is possible that the API user will pass NULL to reset the state
(also NULL is not the only invalid value for a Windows handle).
There is no check for Unix FD, neither should be here.

It's simpler and more future-proof to just say "interrupt handle resources"

It's not an array anymore.

"Event list array" sound like an array of lists,

This is problematic way to do this.
The reason to use rte_malloc vs malloc should be determined by usage.

If the pointer will be shared between primary/secondary process then
it has to be in hugepages (ie rte_malloc). If it is not shared then
then use regular malloc.

But what you have done is created a method which will be
a latent bug for anyone using primary/secondary process.

Either:
    intr_handle is not allowed to be used in secondary.
      Then always use malloc().
Or.
    intr_handle can be used by both primary and secondary.
    Then always use rte_malloc().
    Any code path that allocates intr_handle before pool is
    ready is broken.

Hi Stephan,

Till V2, I implemented this API in a way where user of the API can choose
If he wants intr handle to be allocated using malloc or rte_malloc by passing
a flag arg to the rte_intr_instanc_alloc API. User of the API will best know if
the intr handle is to be shared with secondary or not.

But after some discussions and suggestions from the community we decided
to drop that flag argument and auto detect on whether rte_malloc APIs are
ready to be used and thereafter make all further allocations via rte_malloc.
Currently alarm subsystem (or any driver doing allocation in constructor) gets
interrupt instance allocated using glibc malloc that too because rte_malloc*
is not ready by rte_eal_alarm_init(), while all further consumers gets instance
allocated via rte_malloc.
 I think this should not cause any issue in primary/secondary model as all interrupt
instance pointer will be shared. Infact to avoid any surprises of primary/secondary
not working we thought of making all allocations via rte_malloc. 

David, Thomas, Dmitry, please add if I missed anything.

Can we please conclude on this series APIs as API freeze deadline (rc1) is very near.

Thanks
Harman

Actually in patch 6, I have made lot of changes to this API wrt nb_intr,
where efds/elist arrays are reallocated based on src->nb_intr and make
intr_handle->nb_intr equal to src->nb_intr. I think those changes can be
moved from patch 6 to patch 2.

Yes the caller should know, but it makes usage more difficult.
Using rte_malloc always is simpler.

Yes the general case is to allocate after rte_malloc is ready.
Anyway a constructor should not allocate complicate things.

Yes

I understand Stephen's concern but I think this choice is a good compromise.
Ideally we should avoid doing real stuff in constructors.

I vote for keeping this design.

[dpdk-dev] [PATCH v4 0/7] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):
https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s

Bg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: malloc: introduce malloc is ready API
This patch introduces a new API which tells if DPDK memory
subsystem is initialized and rte_malloc* APIs are ready to be
used. If rte_malloc* are setup, memory for interrupt instance
is allocated using rte_malloc else using traditional heap APIs.

Patch 2: eal/interrupts: implement get set APIs
This patch provides prototypes and implementation of all the new
get set APIs. Alloc APIs are implemented to allocate memory for
interrupt handle instance. Currently most of the drivers defines
interrupt handle instance as static but now it cant be static as
size of rte_intr_handle is unknown to all the drivers. Drivers are
expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.
This patch also rearranges the headers related to interrupt
framework. Epoll related definitions prototypes are moved into a
new header i.e. rte_epoll.h and APIs defined in rte_eal_interrupts.h
which were driver specific are moved to rte_interrupts.h (as anyways
it was accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 3: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 4: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 5: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 6: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 7: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

v4:
* Rectified some typo in the APIs documentation.
* Better names for some internal variables.

[dpdk-dev] [PATCH v4 1/7] malloc: introduce malloc is ready API

[Harman Kalra]

Implementing a new API get the state if DPDK memory management
APIs are initialized.
One of the use case of this API is while allocating an interrupt
instance, if malloc APIs are ready memory for interrupt handles
should be allocated via rte_malloc_* APIs else glibc malloc APIs
are used. Eg. Alarm subsystem is initialised before DPDK memory
infra setup and it allocates an interrupt handle.

[dpdk-dev] [PATCH v4 2/7] eal/interrupts: implement get set APIs

[Harman Kalra]

Prototype/Implement get set APIs for interrupt handle fields.
User won't be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

[dpdk-dev] [PATCH v4 3/7] eal/interrupts: avoid direct access to interrupt handle

[Harman Kalra]

Making changes to the interrupt framework to use interrupt handle
APIs to get/set any field. Direct access to any of the fields
should be avoided to avoid any ABI breakage in future.

[dpdk-dev] [PATCH v4 5/7] drivers: remove direct access to interrupt handle

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [PATCH v4 6/7] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

Hi Dmitry,

I have addressed all your comments in V4, kindly review.
Regarding this particular comment, I have not made any changes as I already
explained in my previous reply that patch 6 takes care of realloc based on nb_intr,
I thought those changes can be moved from patch 6 to 2, but it's not possible because
till patch 5, arrays efds, elist are kept as static arrays to avoid build breakage. While in
patch 6 I made these arrays as pointers and dynamically allocated memory for them.


Thanks
Harman

I get and accept the point why EAL also should use the API.
However, mentioning ABI is still a wrong wording.
There is no ABI between EAL structures and EAL functions by definition of ABI.

That is, before returning 0 above for a secondary process
malloc_ready should be set unconditionally.

Please sort symbols alphabetically, this patch moves rte_intr_disable
after rte_intr_enable.

AFAIU, eal_common_interrupts.c hosts those new symbols and this file

There is no reason to filter interrupts symbols for Windows, is there?

I think goto not required, as we not setting wake_thread = 1 here,
API will just return error after unlocking the spinlock and trace.

Just to emphasize, we're talking about FreeBSD implementation.
There is no "wake_thread" variable there, so "goto fail" is needed.
Your consideration would be valid for similar code in Linux EAL.

There is no technical reason.
I suggested not exporting those that make no sense on Windows.
If this creates complications, let's export them all.

Just as a comment, bus scanning is the real issue, not the alarms.
Alarms could be initialized after the memory management
(but it's irrelevant because their handle is not accessed from the outside).
However, MM needs to know bus IOVA requirements to initialize,
which is usually determined by at least bus device requirements.

What do you mean? Aren't we discussing the issue
that those allocated early are not shared?

> not working we thought of making all allocations via rte_malloc. 

I don't see why anyone would not make them shared.
In order to only use rte_malloc(), we need:
1. In bus drivers, move handle allocation from scan to probe stage.
2. In EAL, move alarm initialization to after the MM.
It all can be done later with v3 design---but there are out-of-tree drivers.
We need to force them to make step 1 at some point.
I see two options:
a) Right now have an external API that only works with rte_malloc()
   and internal API with autodetection. Fix DPDK and drop internal API.
b) Have external API with autodetection. Fix DPDK.
   At the next ABI breakage drop autodetection and libc-malloc.

I support v3 design with no options and autodetection,
because that's the interface we want in the end.
Implementation can be improved later.

In most cases "goto fail" could be "return -rte_errno".
How about this (feel free to ignore)?

This is too much implementation detail and not very specific from user PoV.
Suggestion:

	After rte_eal_init() has finished, it allocates from DDPK heap,

	it allocates from the normal heap during initial bus scanning.

Hi All,

I came across 2 issues introduced with auto detection mechanism.
1. In case of primary secondary model.  Primary application is started which makes lots of allocations via
rte_malloc*
    
    Secondary side:
    a. Secondary starts, in its "rte_eal_init()" it makes some allocation via rte_*, and in one of the allocation
request for heap expand is made as current memseg got exhausted. (malloc_heap_alloc_on_heap_id ()->
   alloc_more_mem_on_socket()->try_expand_heap())
   b. A request to primary for heap expand is sent. Please note secondary holds the spinlock while making
the request. (malloc_heap_alloc_on_heap_id ()->rte_spinlock_lock(&(heap->lock));)

   Primary side:
   a. Primary receives the request, install a new hugepage and setups up the heap (handle_alloc_request())
   b. To inform all the secondaries about the new memseg, primary sends a sync notice where it sets up an 
alarm (rte_mp_request_async ()->mp_request_async()).
   c. Inside alarm setup API, we register an interrupt callback.
   d. Inside rte_intr_callback_register(), a new interrupt instance allocation is requested for "src->intr_handle"
   e. Since memory management is detected as up, inside "rte_intr_instance_alloc()", call to "rte_zmalloc" for
allocating memory and further inside "malloc_heap_alloc_on_heap_id()", primary will experience a deadlock
while taking up the spinlock because this spinlock is already hold by secondary.


2. "eal_flags_file_prefix_autotest" is failing because the spawned process by this tests are expected to cleanup
their hugepage traces from respective directories (eg /dev/hugepage). 
a. Inside eal_cleanup, rte_free()->malloc_heap_free(), where element to be freed is added to the free list and
checked if nearby elements can be joined together and form a big free chunk (malloc_elem_free()).
b. If this free chunk is big enough than the hugepage size, respective hugepage can be uninstalled after making
sure no allocation from this hugepage exists. (malloc_heap_free()->malloc_heap_free_pages()->eal_memalloc_free_seg())

But because of interrupt allocations made for pci intr handles (used for VFIO) and other driver specific interrupt
handles are not cleaned up in "rte_eal_cleanup()", these hugepage files are not removed and test fails.

There could be more such issues, I think we should firstly fix the DPDK.
1. Memory management should be made independent and should be the first thing to come up in rte_eal_init()
2. rte_eal_cleanup() should be exactly opposite to rte_eal_init(), just like bus_probe, we should have bus_remove
to clean up all the memory allocations.

Regarding this IRQ series, I would like to fall back to our original design i.e. rte_intr_instance_alloc() should take
an argument whether its memory should be allocated using glibc malloc or rte_malloc*. Decision for allocation
(malloc or rte_malloc) can be made on fact that in the existing code is the interrupt handle is shared?
Eg.  a. In case of alarm intr_handle was global entry and not confined to any structure, so this can be allocated from
normal malloc.
b. PCI device, had static entry for intr_handle inside "struct rte_pci_device" and memory for struct rte_pci_device is
via normal malloc, so it intr_handle can also be malloc'ed
c. Some driver with intr_handle inside its priv structure, and this priv structure gets allocated via rte_malloc, so
Intr_handle can also be rte_malloc.

Later once DPDK is fixed up, this argument can be removed and all allocations can be via rte_malloc family without
any auto detection.


David, Dmitry, Thomas, Stephan, please share your views....

Harman

Sad to hear. But it's a great and thorough analysis.

As I have explained, buses must be able to report IOVA requirement
at this point (`get_iommu_class()` bus method).
Either `scan()` must complete before that
or `get_iommu_class()` must be able to work before `scan()` is called.

Yes. For most buses it will be just "unplug each device".
In fact, EAL could do it with `unplug()`, but it is not mandatory.

- Sorry, my memory is too short, did we describe where we need to
share rte_intr_handle objects?

I spent some time looking at uses of rte_intr_handle objects.

In many cases intr_handle objects are referenced in malloc() objects.
The cases where rte_intr_handle are shared is in per device private
bits in drivers.

A intr_handle often contains fds.
For them to be used in mp setups, there needs to be a big machinery
with SCM_RIGHTS but I see only 3 drivers which actually reference
this.
So if intr_handle fds are accessed by multiple processes, their
content probably makes no sense wrt fds.


From these two hints, I think we are going backwards, and the main
usecase is that those rte_intr_instance objects are not used in mp.
I even think they are never accessed from other processes.
But I am not sure.


- Seeing how time it short for rc1, I am ok with
rte_intr_instance_alloc() taking a flag argument.
And we can still go back on this API later.

Can we agree on the flag name?
rte_malloc() interest is that it makes objects shared for mp, so how
about RTE_INTR_INSTANCE_F_SHARED ?

I implemented a rough bus_remove which was similar to unplug, faced
some issue. Not sure but some drivers might not be supporting hotplug, for
them unplug might be a challenge.

Intr handle objects are shared in very few drivers.

Yes, in V2 design I allocated memory using glibc malloc for such instances by
passing respective flag.

Those drivers will allocate using SHARED flag.

Sure, I will revert back to original design and send V5 by tomorrow.

Yeah, it sounds good:
RTE_INTR_INSTANCE_F_SHARED  - rte_malloc
RTE_INTR_INSTANCE_F_PRIVATE - malloc


Thanks David, Dmitry, Thomas, Stephan for reviewing the series thoroughly and providing

[dpdk-dev] [PATCH v5 0/6] make rte_intr_handle internal

[Harman Kalra]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):
https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s

Bg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

Details on each patch of the series:
Patch 1: eal/interrupts: implement get set APIs
This patch provides prototypes and implementation of all the new
get set APIs. Alloc APIs are implemented to allocate memory for
interrupt handle instance. Currently most of the drivers defines
interrupt handle instance as static but now it cant be static as
size of rte_intr_handle is unknown to all the drivers. Drivers are
expected to allocate interrupt instances during initialization
and free these instances during cleanup phase.
This patch also rearranges the headers related to interrupt
framework. Epoll related definitions prototypes are moved into a
new header i.e. rte_epoll.h and APIs defined in rte_eal_interrupts.h
which were driver specific are moved to rte_interrupts.h (as anyways
it was accessible and used outside DPDK library. Later in the series
rte_eal_interrupts.h is removed.

Patch 2: eal/interrupts: avoid direct access to interrupt handle
Modifying the interrupt framework for linux and freebsd to use these
get set alloc APIs as per requirement and avoid accessing the fields
directly.

Patch 3: test/interrupt: apply get set interrupt handle APIs
Updating interrupt test suite to use interrupt handle APIs.

Patch 4: drivers: remove direct access to interrupt handle fields
Modifying all the drivers and libraries which are currently directly
accessing the interrupt handle fields. Drivers are expected to
allocated the interrupt instance, use get set APIs with the allocated
interrupt handle and free it on cleanup.

Patch 5: eal/interrupts: make interrupt handle structure opaque
In this patch rte_eal_interrupt.h is removed, struct rte_intr_handle
definition is moved to c file to make it completely opaque. As part of
interrupt handle allocation, array like efds and elist(which are currently
static) are dynamically allocated with default size
(RTE_MAX_RXTX_INTR_VEC_ID). Later these arrays can be reallocated as per
device requirement using new API rte_intr_handle_event_list_update().
Eg, on PCI device probing MSIX size can be queried and these arrays can
be reallocated accordingly.

Patch 6: eal/alarm: introduce alarm fini routine
Introducing alarm fini routine, as the memory allocated for alarm interrupt
instance can be freed in alarm fini.

Testing performed:
1. Validated the series by running interrupts and alarm test suite.
2. Validate l3fwd power functionality with octeontx2 and i40e intel cards,
   where interrupts are expected on packet arrival.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

v4:
* Rectified some typo in the APIs documentation.
* Better names for some internal variables.

v5:
* Reverted back to passing flag to instance alloc API, as
with auto detect some multiprocess issues existing in the
library were causing tests failure.
* Rebased to top of tree.

[dpdk-dev] [PATCH v5 1/6] eal/interrupts: implement get set APIs

[Harman Kalra]

Prototype/Implement get set APIs for interrupt handle fields.
User wont be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

[dpdk-dev] [PATCH v5 4/6] drivers: remove direct access to interrupt handle

[Harman Kalra]

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers and libraries access the
interrupt handle fields.

[dpdk-dev] [PATCH v5 5/6] eal/interrupts: make interrupt handle structure opaque

[Harman Kalra]

Moving interrupt handle structure definition inside the c file
to make its fields totally opaque to the outside world.

Dynamically allocating the efds and elist array os intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

Nits:

"could" -> "will be"

"within primary secondary process" ->
"between primary and secondary processes"

You previously suggested PRIVATE instead of UNSHARED,
it sounded better, but no strog opinion.

It returns flags passed on allow,
so return value type and description is inaccurate.
Should be uint32_t and a reference to the flag constants.

Why not just get the flags and use them as-is to allocate a new instance?
If you care to use only these flags even if there are others,
a mask can be used.

Wasn't this member going to be removed since v1?

Ray, do you agree?
MAX enum members have been scheduled for removal long ago.
This one even seems unlikely to be used as array size and break anything.

Alarms are initialized after tracing, so they should be finalized after.

"...finalized before", sorry. 

[dpdk-dev] [PATCH v6 0/9] make rte_intr_handle internal

[David Marchand]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):
https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s
preadsheets_d_1betlC000ua5SsSiJIcC54mCCCJnW6voH5Dqv9UxeyfE_edit-23gid-

Bg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

v4:
* Rectified some typo in the APIs documentation.
* Better names for some internal variables.

v5:
* Reverted back to passing flag to instance alloc API, as
with auto detect some multiprocess issues existing in the
library were causing tests failure.
* Rebased to top of tree.

v6:
* renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
* changed API and removed need for alloc_flag content exposure
  (see rte_intr_instance_dup() in patch 1 and 2),
* exported all symbols for Windows,
* fixed leak in unit tests in case of alloc failure,
* split (previously) patch 4 into three patches
  * (now) patch 4 only concerns alarm and (previously) patch 6 cleanup bits
    are squashed in it,
  * (now) patch 5 concerns other libraries updates,
  * (now) patch 6 concerns drivers updates:
    * instance allocation is moved to probing for auxiliary,
    * there might be a bug for PCI drivers non requesting
      RTE_PCI_DRV_NEED_MAPPING, but code is left as v5,
* split (previously) patch 5 into three patches
  * (now) patch 7 only hides structure, but keep it in a EAL private
    header, this makes it possible to keep info in tracepoints,
  * (now) patch 8 deals with VFIO/UIO internal fds merge,
  * (now) patch 9 extends event list,

[dpdk-dev] [PATCH v6 1/9] interrupts: add allocator and accessors

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Prototype/Implement get set APIs for interrupt handle fields.
User won't be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

Changes since v5:
- renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
- used a single bit to mark instance as shared (default is private),
- removed rte_intr_instance_copy / rte_intr_instance_alloc_flag_get
  with a single rte_intr_instance_dup helper,
- made rte_intr_vec_list_alloc alloc_flags-aware,
- exported all symbols for Windows,

[dpdk-dev] [PATCH v6 4/9] alarm: remove direct access to interrupt handle

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the libraries access the interrupt handle fields.

Implementing alarm cleanup routine, where the memory allocated
for interrupt instance can be freed.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v5:
- split from patch4,
- merged patch6,
- renamed rte_eal_alarm_fini as rte_eal_alarm_cleanup,

[dpdk-dev] [PATCH v6 7/9] interrupts: make interrupt handle structure opaque

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Moving interrupt handle structure definition inside a EAL private
header to make its fields totally opaque to the outside world.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v5:
- let rte_intr_handle fields untouched:
  - split vfio / uio fd renames in a separate commit,
  - split event list update in a separate commit,
- moved rte_intr_handle definition to a EAL private header,
- preserved dumping all info in interrupt tracepoints,

VFIO/UIO are mutually exclusive, storing file descriptor in a single

[dpdk-dev] [PATCH v7 0/9] make rte_intr_handle internal

[David Marchand]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):
https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_s

Bg1shODpAy3RQk-H-0uQx5icRfUBf9dtCp4&e=

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

v4:
* Rectified some typo in the APIs documentation.
* Better names for some internal variables.

v5:
* Reverted back to passing flag to instance alloc API, as
with auto detect some multiprocess issues existing in the
library were causing tests failure.
* Rebased to top of tree.

v6:
* renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
* changed API and removed need for alloc_flag content exposure
  (see rte_intr_instance_dup() in patch 1 and 2),
* exported all symbols for Windows,
* fixed leak in unit tests in case of alloc failure,
* split (previously) patch 4 into three patches
  * (now) patch 4 only concerns alarm and (previously) patch 6 cleanup bits
    are squashed in it,
  * (now) patch 5 concerns other libraries updates,
  * (now) patch 6 concerns drivers updates:
    * instance allocation is moved to probing for auxiliary,
    * there might be a bug for PCI drivers non requesting
      RTE_PCI_DRV_NEED_MAPPING, but code is left as v5,
* split (previously) patch 5 into three patches
  * (now) patch 7 only hides structure, but keep it in a EAL private
    header, this makes it possible to keep info in tracepoints,
  * (now) patch 8 deals with VFIO/UIO internal fds merge,
  * (now) patch 9 extends event list,

v7:
* fixed compilation on FreeBSD,
* removed unused interrupt handle in FreeBSD alarm code,
* fixed interrupt handle allocation for PCI drivers without
  RTE_PCI_DRV_NEED_MAPPING,

[dpdk-dev] [PATCH v7 1/9] interrupts: add allocator and accessors

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Prototype/Implement get set APIs for interrupt handle fields.
User won't be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

Changes since v5:
- renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
- used a single bit to mark instance as shared (default is private),
- removed rte_intr_instance_copy / rte_intr_instance_alloc_flag_get
  with a single rte_intr_instance_dup helper,
- made rte_intr_vec_list_alloc alloc_flags-aware,
- exported all symbols for Windows,

[dpdk-dev] [PATCH v7 4/9] alarm: remove direct access to interrupt handle

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the libraries access the interrupt handle fields.

Implementing alarm cleanup routine, where the memory allocated
for interrupt instance can be freed.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v6:
- removed unused interrupt handle in FreeBSD alarm code,

Changes since v5:
- split from patch4,
- merged patch6,
- renamed rte_eal_alarm_fini as rte_eal_alarm_cleanup,

[dpdk-dev] [PATCH v7 6/9] drivers: remove direct access to interrupt handle

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the drivers access the interrupt handle fields.

Changes since v6:
- fixed interrupt handle allocation for drivers without
  RTE_PCI_DRV_NEED_MAPPING,

Changes since v5:
- moved instance allocation to probing for auxiliary,
- fixed dev_irq_register() return value sign on error for
  drivers/common/cnxk/roc_irq.c,

[dpdk-dev] [PATCH v7 7/9] interrupts: make interrupt handle structure opaque

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Moving interrupt handle structure definition inside a EAL private
header to make its fields totally opaque to the outside world.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v5:
- let rte_intr_handle fields untouched:
  - split vfio / uio fd renames in a separate commit,
  - split event list update in a separate commit,
- moved rte_intr_handle definition to a EAL private header,
- preserved dumping all info in interrupt tracepoints,

VFIO/UIO are mutually exclusive, storing file descriptor in a single

[dpdk-dev] [PATCH v8 0/9] make rte_intr_handle internal

[David Marchand]

Moving struct rte_intr_handle as an internal structure to
avoid any ABI breakages in future. Since this structure defines
some static arrays and changing respective macros breaks the ABI.
Eg:
Currently RTE_MAX_RXTX_INTR_VEC_ID imposes a limit of maximum 512
MSI-X interrupts that can be defined for a PCI device, while PCI
specification allows maximum 2048 MSI-X interrupts that can be used.
If some PCI device requires more than 512 vectors, either change the
RTE_MAX_RXTX_INTR_VEC_ID limit or dynamically allocate based on
PCI device MSI-X size on probe time. Either way its an ABI breakage.

Change already included in 21.11 ABI improvement spreadsheet (item 42):

This series makes struct rte_intr_handle totally opaque to the outside
world by wrapping it inside a .c file and providing get set wrapper APIs
to read or manipulate its fields.. Any changes to be made to any of the
fields should be done via these get set APIs.
Introduced a new eal_common_interrupts.c where all these APIs are defined
and also hides struct rte_intr_handle definition.

v1:
* Fixed freebsd compilation failure
* Fixed seg fault in case of memif

v2:
* Merged the prototype and implementation patch to 1.
* Restricting allocation of single interrupt instance.
* Removed base APIs, as they were exposing internally
allocated memory information.
* Fixed some memory leak issues.
* Marked some library specific APIs as internal.

v3:
* Removed flag from instance alloc API, rather auto detect
if memory should be allocated using glibc malloc APIs or
rte_malloc*
* Added APIs for get/set windows handle.
* Defined macros for repeated checks.

v4:
* Rectified some typo in the APIs documentation.
* Better names for some internal variables.

v5:
* Reverted back to passing flag to instance alloc API, as
with auto detect some multiprocess issues existing in the
library were causing tests failure.
* Rebased to top of tree.

v6:
* renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
* changed API and removed need for alloc_flag content exposure
  (see rte_intr_instance_dup() in patch 1 and 2),
* exported all symbols for Windows,
* fixed leak in unit tests in case of alloc failure,
* split (previously) patch 4 into three patches
  * (now) patch 4 only concerns alarm and (previously) patch 6 cleanup bits
    are squashed in it,
  * (now) patch 5 concerns other libraries updates,
  * (now) patch 6 concerns drivers updates:
    * instance allocation is moved to probing for auxiliary,
    * there might be a bug for PCI drivers non requesting
      RTE_PCI_DRV_NEED_MAPPING, but code is left as v5,
* split (previously) patch 5 into three patches
  * (now) patch 7 only hides structure, but keep it in a EAL private
    header, this makes it possible to keep info in tracepoints,
  * (now) patch 8 deals with VFIO/UIO internal fds merge,
  * (now) patch 9 extends event list,

v7:
* fixed compilation on FreeBSD,
* removed unused interrupt handle in FreeBSD alarm code,
* fixed interrupt handle allocation for PCI drivers without
  RTE_PCI_DRV_NEED_MAPPING,

v8:
* lowered logs level to DEBUG in sanity checks,
* fixed corner case with vector list access,

[dpdk-dev] [PATCH v8 1/9] interrupts: add allocator and accessors

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Prototype/Implement get set APIs for interrupt handle fields.
User won't be able to access any of the interrupt handle fields
directly while should use these get/set APIs to access/manipulate
them.

Internal interrupt header i.e. rte_eal_interrupt.h is rearranged,
as APIs defined are moved to rte_interrupts.h and epoll specific
definitions are moved to a new header rte_epoll.h.
Later in the series rte_eal_interrupt.h will be removed.

Changes since v7:
- lowered checks log level to DEBUG,
- removed asserts on vector list size, and fixed check on list size
  for drivers like mlx5 who expects list is not initialized,

Changes since v5:
- renamed RTE_INTR_INSTANCE_F_UNSHARED as RTE_INTR_INSTANCE_F_PRIVATE,
- used a single bit to mark instance as shared (default is private),
- removed rte_intr_instance_copy / rte_intr_instance_alloc_flag_get
  with a single rte_intr_instance_dup helper,
- made rte_intr_vec_list_alloc alloc_flags-aware,
- exported all symbols for Windows,

[dpdk-dev] [PATCH v8 4/9] alarm: remove direct access to interrupt handle

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Removing direct access to interrupt handle structure fields,
rather use respective get set APIs for the same.
Making changes to all the libraries access the interrupt handle fields.

Implementing alarm cleanup routine, where the memory allocated
for interrupt instance can be freed.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v6:
- removed unused interrupt handle in FreeBSD alarm code,

Changes since v5:
- split from patch4,
- merged patch6,
- renamed rte_eal_alarm_fini as rte_eal_alarm_cleanup,

[dpdk-dev] [PATCH v8 7/9] interrupts: make interrupt handle structure opaque

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Moving interrupt handle structure definition inside a EAL private
header to make its fields totally opaque to the outside world.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since v5:
- let rte_intr_handle fields untouched:
  - split vfio / uio fd renames in a separate commit,
  - split event list update in a separate commit,
- moved rte_intr_handle definition to a EAL private header,
- preserved dumping all info in interrupt tracepoints,

[dpdk-dev] [PATCH v8 8/9] interrupts: rename device specific file descriptor

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

VFIO/UIO are mutually exclusive, storing file descriptor in a single
field is enough.

[dpdk-dev] [PATCH v8 9/9] interrupts: extend event list

[David Marchand]

From: Harman Kalra <hkalra@marvell.com>

Dynamically allocating the efds and elist array of intr_handle
structure, based on size provided by user. Eg size can be
MSIX interrupts supported by a PCI device.

Signed-off-by: Harman Kalra <hkalra@marvell.com>
Signed-off-by: David Marchand <david.marchand@redhat.com>
Acked-by: Dmitry Kozlyuk <dmitry.kozliuk@gmail.com>

Changes since v6:
- removed unneeded checks on elist/efds array initialisation,

Changes since v5:
- split from patch5,

Hi Harman,
When we test dpdk-21.11-rc1, find a bug https://bugs.dpdk.org/show_bug.cgi?id=845, its bad commit id is c2bd9367e18f5b00c1a3c5eb281a512ef52c5dfd/Author: Harman Kalra <hkalra@marvell.com>
Could you pls have a look?

Re: [dpdk-dev] [PATCH v8 9/9] interrupts: extend event list

[Ji, Kai]

Hi Harman, 

This patch is causing QAT failed during interrupt init, the event list does not support interrupt count size zero in QAT case. 

There is also Bugzilla relate to this issue: https://bugs.dpdk.org/show_bug.cgi?id=843

Regards

Kai

(We could avoid updating event list if it is large enough but) your
problem must be that QAT does not have MSIX.

Can you try this quick fix?
