This is a PoC for hiding the rte_bus object and mark associated API
as internal.
A good amount of the patches are preparation work on rte_bus.h,
rte_dev.h, rte_devargs.h and rte_eal.h headers, removing dependencies
between them. This is something I had in store for some time, maybe I
should have dropped it from the PoC, but I think those cleanups are
worth it in any case.
The last two patches do the actual job: add accessors and make the
rte_bus object opaque to non internal users.
Disclaimer: this series is a bit rushed (I brute forced compilation
tests in GHA so that it passes between patches, but there still may be
something broken...).
Not surprisingly, the ABI check in the CI is expected to fail.
Comments welcome.
I also hope we can do the same work on other generic objects
(rte_driver, rte_device), but this is another story.

Rely on a local flag rather than dereference a bus object.
This will help next commits.

There is no in-tree user for this accessor that returns the PCI bus
object.
On the other hand, a bus object can be retrieved by name using
rte_bus_find_by_name.
We can remove driver specific API.

For any bus that does not support device iteration, rte_dev_iterator_init
both returned an error code and logged an error message.
An application (like testpmd) that only wants to list devices, would have
no choice but to inspect a bus object to avoid spewing error logs.
Make those log messages debug level, and remove the check in testpmd.

RTE_FUNC_PTR_OR_* macros have nothing to do with the rte_device object
and associated API.
Move them to rte_common.h and include it where needed.

We don't need to include rte_bus.h.
Only a forward declaration of rte_bus and an inclusion of rte_dev.h are
needed.

iova enum definition does not need to be defined as part of the bus API.
Move it to rte_eal.h.
With this step, rte_eal.h does not depend on rte_bus.h and rte_dev.h.
Fix existing code that was relying on these implicit inclusions.

There is no need for a back reference to a singleton object in the bus
driver objects: each function is contextually aware of which bus object
it should manipulate.

Now that there is no bus specific object referenced in the driver
objects, we can hide rte_dpaa_bus, rte_fslmc_bus, rte_pci_bus,
rte_vmbus_bus specific structures into their bus code.
While at it:
- move enumerators only used in the bus code itself,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and update code that relied on it,

since we're overhauling anyway we could follow suit with a number of the
lessons from posix apis e.g. pthread and eliminate typed pointers for a
little extra value.

to avoid people tripping over mishandling pointers in/out of the api
surface taking the opaque object you could declare opaque handle for the
api to operate on instead. it would force the use of a cast in the
implementation but would avoid accidental void * of the wrong thing that
got cached being passed in. if the cast was really undesirable just
whack it under an inline / internal function.
e.g. make the opaque object an explicit type.
struct {
uintptr_t opaque;
} rte_bus_handle_t;
// implementation
rte_bus_handle_t
rte_bus_find(rte_bus_handle_t start,
rte_bus_cmp_t cmp, const void *data)
{
struct rte_bus *bus = (struct rte_bus *)start.opaque;
// do bus things on bus
return {.opaque = whatever};
}
then you will get hard compile time failure if someone messes up
argument passing.
e.g.
void *somerandomp = ...;
...
rte_bus_find(somerandomp, ...); // compile fail
i would actually suggest this wrapping in a struct / handle approach for
any opaque object that is passed over the api surface. the change is
bigger of course...
it has various other advantages when/if we decide to make the bus/driver
surface stable in abi which i understand is not a promise dpdk makes
right now but still we might one day.
anyway, just a suggestion. i like the series either way.

I don't like that because it least to dangerous casts in the internal code.
Better to keep the the type of the object. As long as the API only passes
around an pointer to a struct, without exposing the contents of the struct;
it is safer and easier to debug.

as i mentioned you can use an inline/internal function or even a macro
to hide the cast, you could provide some additional integrity checks
here if desired as a value add.
the fact that you expose that it is a struct is an internal
implementation detail, if truly opaque tomorrow you could convert it
to a simple integer that indexes or enumerates something and prevents
any meaningful interpretation in the application.
when you say it is safer to debug i think you mean for dpdk devs not the
application developer because unless the app developer does something
really gross/dangerous casting they really can't "mishandle" the opaque
object except to use one that isn't initialized at all which we
can detect and handle internally in a general way.
i will however concede there would be slightly more finger work when
debugging dpdk itself since gdb / debugger doesn't automatically infer
type so you end up having to tell gdb what is in the uintptr_t.
anyway just drawing from experience in the driver frameworks we maintain
in windows, i think one of our regrets is that we didn't do this from
day 1 and subsequentl that we initially only used one opaque type
instead of defining separate (not implicitly convertable) types to each
opaque type.

It seems to be a difference in style/taste.
The Linux/Unix side prefers opaque structure pointers.
Windows (and LLVM) uses numeric handles.
At this point DPDK should follow the Linux bus.

it's not i've sited at least one example of a mistake that becomes a
compile time failure where application code is incorrectly authored
where use of a pointer offers no such protection.

dpdk is multi-platform and unix does not necessarily standardize on
pointer to struct for opaque objects. freebsd has many apis notably
bus_space that does uses handles and as previously mentioned posix
threads uses handles.
i understand that linux is an important platform but it isn't the only
platform dpdk targets and just because it is important doesn't mean it
should always enjoy being the defacto standard.
anyway, i'll leave it for the patch author to decide. i still like the
patch series either way. i just think this would make applications more
robust.

Thanks for this feedback Tyler.
I would lean towards Stephen opinion atm, but I am not decided yet.
For now, I'll post a v2, extending the series to other internal objects.
We can conclude on this topic during 22.11.

To: dev
This is a PoC for hiding the rte_bus, rte_driver and rte_device objects.
And mark associated driver only API as internal.
A good amount of the patches are preparation work on rte_bus.h,
rte_dev.h, rte_devargs.h and rte_eal.h headers, removing dependencies
between them. This is something I had in store for some time, maybe I
should have dropped it from the PoC, but I think those cleanups are
worth it in any case.
Then PCI bus specific handling are moved from unit tests and examples,
though there is still a special case left in testpmd that may require a
new API, to be discussed.
After this series, driver-only API headers for registering to buses are
not exported anymore, unless the enable_driver_sdk meson option is
selected.
New accessors for rte_bus, rte_driver and rte_device have been added,
marked with an experimental tag though we may declare them as stable
right away so that users can switch to them directly. That's also
something to agree on.
I simplified my series and switched to only update "external" users,
like app/ and examples/ files.
We need some checkpatch new checks to be sure we won't get some
driver-only headers included in these areas. That's something I'll work
on in the non RFC series.
"Internal" users are simply using the internal headers. That helps
greatly reducing the size of the changes.
Disclaimer: again, in this v2, this series is a bit rushed (I brute forced
compilation tests in GHA so that it passes between patches, but there still
may be something broken...).
Not surprisingly, the ABI check in the CI is expected to fail.
Comments welcome.
Changes since RFC v1:
- added two more cleanups (new patch 3 and 4) for unit test and examples
relying on PCI specific info,
- went on with masking rte_driver and rte_device too,

Rely on a local flag rather than dereference a bus object.
This will help next commits.

There is no in-tree user for this accessor that returns the PCI bus
object.
On the other hand, a bus object can be retrieved by name using
rte_bus_find_by_name.
We can remove driver specific API.

Rely on the generic device name rather than restrict to only supporting
PCI devices.

For any bus that does not support device iteration, rte_dev_iterator_init
both returned an error code and logged an error message.
An application (like testpmd) that only wants to list devices, would have
no choice but to inspect a bus object to avoid spewing error logs.
Make those log messages debug level, and remove the check in testpmd.

We don't need to include rte_bus.h.
Only a forward declaration of rte_bus and an inclusion of rte_dev.h are
needed.

iova enum definition does not need to be defined as part of the bus API.
Move it to rte_eal.h.
With this step, rte_eal.h does not depend on rte_bus.h and rte_dev.h.
Fix existing code that was relying on these implicit inclusions.

There is no need for a back reference to a singleton object in the bus
driver objects: each function is contextually aware of which bus object
it should manipulate.

Now that there is no bus specific object referenced in the driver
objects, we can hide rte_dpaa_bus, rte_fslmc_bus, rte_pci_bus,
rte_vmbus_bus specific structures into their bus code.
While at it:
- move enumerators only used in the bus code itself,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and update code that relied on it,
Signed-off-by: David Marchand <david.marchand@redhat.com>

Changes since RFC v1:
- dropped kni UT and ethtool example changes after new cleanup was added,
- cleaned ifgpa and vdev bus,

Make rte_bus opaque for non internal users.
This will make extending this object possible without breaking the ABI.
Introduce a new driver header and move rte_bus definition and helpers.
Update drivers and library to use the internal header.
Signed-off-by: David Marchand <david.marchand@redhat.com>
---
Changes since RFC v1:
- update all existing users of the public header to use the internal one,

Those headers are for drivers as they include ethdev_driver.h, a
driver-only header.

From: David Marchand @ 2022-07-09 8:26 UTC (permalink / raw)
To: dev; +Cc: Rosen Xu, Ray Kinsella, Tianfei zhang
Remove unused symbols (exposed only in an internal header which
guarantees that no application out there relied on them).
Remove rte_ prefix and inline the rest to avoid having to expose them as
global symbols for a relatively small added value.

If you get chance to deconstruct API, switching to a numeric index
is safest similar to what Tyler suggested. Think of ethdev port number
and Posix file descriptor model. The advantage of an index is that
it can be validated more easily by the code that is called.

Looks good to me, lots of work but will the separation internal
and external API's will help in future.

This is a PoC for hiding the rte_bus, rte_driver and rte_device objects.
And mark associated driver only API as internal.
A good amount of the patches are preparation work on rte_bus.h,
rte_dev.h, rte_devargs.h and rte_eal.h headers, removing dependencies
between them.
PCI bus specific handling are removed from testpmd, unit tests and
examples.
After this series, driver-only API headers for registering to buses are
not exported anymore, unless the enable_driver_sdk meson option is
selected.
New accessors for rte_bus, rte_driver and rte_device have been added,
marked with an experimental tag first when introducing them, and later
in the series marked as stable since external users will want to use
those drop-in replacements right away.
A check is added to ensure we won't pollute app/ and examples/ again,
though some unit tests are left intentionnally untouched as they test
some internals of DPDK.
Comments welcome.
Changes since RFC v2:
- added check for additions of include .*_(driver|pmd)\.h in apps and
examples,
- dropped legacy/debug testpmd commands to read PCI BAR0 registers,
- dropped patches on bbdev, ethdev, rawdev driver headers for now,
- reordered patches and separated changes per bus type to ease review,
- added more accessor for device,
- introduced rte_dev_bus_info to provide a Bus specific description of
a device, a first use is for providing a PCI device vendor / device
identifiers that are otherwise unavailable through a generic existing
API,
Changes since RFC v1:
- added two more cleanups (new patch 3 and 4) for unit test and examples
relying on PCI specific info,
- went on with masking rte_driver and rte_device too,

Rely on a local flag rather than dereference a bus object.
This will help next commits.

There is no in-tree user for this accessor that returns the PCI bus
object.
On the other hand, a bus object can be retrieved by name using
rte_bus_find_by_name.
We can remove this driver specific API.

Those commands date back to the early stages of DPDK when only PCI
devices were supported.
At the time, developers may have used those commands to help in
debugging their buggy^Wwork in progress drivers.
Removing them, we can drop the dependency on the PCI bus and library and
make testpmd bus agnostic.

-Register Functions
-------------------
-
-The Register Functions can be used to read from and write to registers on the network card referenced by a port number.
-This is mainly useful for debugging purposes.
-Reference should be made to the appropriate datasheet for the network card for details on the register addresses
-and fields that can be accessed.
-
-read reg
-~~~~~~~~
-
-Display the value of a port register::
-
- testpmd> read reg (port_id) (address)
-
-For example, to examine the Flow Director control register (FDIRCTL, 0x0000EE000) on an Intel 82599 10 GbE Controller::
-
- testpmd> read reg 0 0xEE00
- port 0 PCI register at offset 0xEE00: 0x4A060029 (1241907241)
-
-read regfield
-~~~~~~~~~~~~~
-
-Display a port register bit field::
-
- testpmd> read regfield (port_id) (address) (bit_x) (bit_y)
-
-For example, reading the lowest two bits from the register in the example above::
-
- testpmd> read regfield 0 0xEE00 0 1
- port 0 PCI register at offset 0xEE00: bits[0, 1]=0x1 (1)
-
-read regbit
-~~~~~~~~~~~
-
-Display a single port register bit::
-
- testpmd> read regbit (port_id) (address) (bit_x)
-
-For example, reading the lowest bit from the register in the example above::
-
- testpmd> read regbit 0 0xEE00 0
- port 0 PCI register at offset 0xEE00: bit 0=1
-
-write reg
-~~~~~~~~~
-
-Set the value of a port register::
-
- testpmd> write reg (port_id) (address) (value)
-
-For example, to clear a register::
-
- testpmd> write reg 0 0xEE00 0x0
- port 0 PCI register at offset 0xEE00: 0x00000000 (0)
-
-write regfield
-~~~~~~~~~~~~~~
-
-Set bit field of a port register::
-
- testpmd> write regfield (port_id) (address) (bit_x) (bit_y) (value)
-
-For example, writing to the register cleared in the example above::
-
- testpmd> write regfield 0 0xEE00 0 1 2
- port 0 PCI register at offset 0xEE00: 0x00000002 (2)
-
-write regbit
-~~~~~~~~~~~~
-
-Set single bit value of a port register::
-
- testpmd> write regbit (port_id) (address) (bit_x) (value)
-
-For example, to set the high bit in the register from the example above::
-
- testpmd> write regbit 0 0xEE00 31 1
- port 0 PCI register at offset 0xEE00: 0x800
