These patches rearrange the management of the devargs on two different
levels.
The first splits the net driver's devargs into two categories,
device-dependent devargs and port-dependent devargs.
Arguments that depend on the device are updated once in the creation of
the shared device context structure, and do not change even if the user
has sent new devargs in the probe again. In contrast, the arguments that
depend on the port are updated separately for each port.
The second layer deals with the parsing of devargs in the common driver.
The common driver once parses the devargs into a dictionary, then sends
it to all the drivers that will use it during the their probing. Each
driver updates within dictionary which keys it has used, then the common
driver checks the updated dictionary and reports about unknown devargs.

The MLX5 net driver supports "probe again". In probing again, it
creates a new ethdev under an existing infiniband device context.
Sibling devices sharing infiniband device context should have compatible
configurations, so some of the devargs given in the probe again, the
ones that are mainly relevant to the sharing device context are sent to
the mlx5_dev_check_sibling_config function which makes sure that they
compatible its siblings.
However, the arguments are adjusted according to the capability of the
device, and the function compares the arguments of the probe again
before the adjustment with the arguments of the siblings after the
adjustment. A user who sends the same values to all siblings may fail in
this comparison if he requested something that the device does not
support and adjusted.
This patch moves the call to the mlx5_dev_check_sibling_config function
after the relevant adjustments.
Fixes: 92d5dd483450 ("net/mlx5: check sibling device configurations mismatch")
Fixes: 2d241515ebaf ("net/mlx5: add devarg for extensive metadata support")

In "dv_xmeta_en" devarg there is an option of dv_xmeta_en=3 which
engages tunnel offload mode. In E-Switch configuration, that mode
implicitly activates dv_xmeta_en=1.
The update according to E-switch support is done immediately after the
first parsing of the devargs, but there is another adjustment later.
This patch moves the adjustment after the second parsing.

The ASO connection tracking structure is initialized once for sharing
device context.
Its release takes place in the close function which is called for each
ethdev individually. i.e. when there is more than one ethdev under the
same sharing device context, it will be destroyed when one of them is
closed. If the other wants to use it later, it may cause it to crash.
In addition, the creation of this structure is performed in the spawn
function. if one of the creations of the objects following it fails, it
is supposed to be destroyed but this does not happen.
This patch moves its release to the sharing device context free function
and thus solves both problems.

The mlx5_alloc_shared_dev_ctx() function has a local variable named
"err" which contains the errno value in case of failure.
When functions called by this function are failed, this variable is
updated with their return value (that should be a positive errno value).
However, some functions doesn't update errno value by themselves or
return negative errno value. If one of them fails, the "err" variable
contains negative value what cause to assertion failure.
This patch updates all functions uses by mlx5_alloc_shared_dev_ctx()
function to update rte_errno and take this value instead of "err" value.

In mlx5_ethdev.c file are implemented those 4 functions:
- mlx5_dev_infos_get
- mlx5_fw_version_get
- mlx5_dev_set_mtu
- mlx5_hairpin_cap_get
In mlx5.h file they are declared twice. First time under mlx5.c file and
second time under mlx5_ethdev.c file.
This patch removes the redundant declaration.

The device arguments are parsed and updated twice during spawning. First
time before creating the share device context, and again later after
updating a default value to one of the arguments.
This patch consolidates them into one parsing and updates the default
values before it.

The HCA attribute structure is field of net configure structure.
It is also field of common configure structure.
There is no need for this duplication, because there is a reference to
the common structure from within the net structures.
This patch removes it from net configure structure and uses the common
config structure instead.

From: Michael Baum @ 2022-01-27 15:39 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The sharing device context structure has a field named "devx" which
indicates if DevX is supported.
The common configure stracture has also field named "devx" with the same
meaning.
There is no need for this duplication, because there is a reference to
the common structure from within the sharing device context structure.
This patch removes it from sharing device context structure and uses the
common config structure instead.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The sharing device context structure has a field named "device_attr"
which s filled by mlx5_os_get_dev_attr() function.
The spawn function calls mlx5_os_get_dev_attr() again and save it to
local variable identical to "device_attr" field.
There is no need for this duplication, because there is a reference to
the sharing device context structure from spawn function.
This patch removes the local "device_attr" from spawn function, and uses
the context's field instead.

This patch adds in SH structure a flag which indicates whether is
E-Switch mode.
When configure "dv_esw_en" from devargs, it is enabled only when is
E-switch mode. So, since dv_esw_en has been configure, it is enough to
check if "dv_esw_en" is valid.
This patch also removes E-Switch mode check when "dv_esw_en" is checked
too.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Rearrange the mlx5_os_get_dev_attr() function in such a way that it
first executes the queries and only then updates the fields.
In addition, it changed its name in preparation for expanding its
operations to configure the capabilities inside it.

From: Michael Baum @ 2022-01-27 15:39 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Move all device configure to be performed by mlx5_os_cap_config()
function instead of the spawn function.
In addition move all relevant fields from mlx5_dev_config structure to
mlx5_dev_cap.

From: Michael Baum @ 2022-01-27 15:39 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Add configuration structure for shared device context. This structure
contains all configurations coming from devargs which oriented to
device. It is a field of shared device context (SH) structure, and is
updated once in mlx5_alloc_shared_dev_ctx() function.
This structure cannot be changed when probing again, so add function to
prevent it. The mlx5_probe_again_args_validate() function creates a
temporary IB context configure structure according to new devargs
attached in probing again, then checks the match between the temporary
structure and the existing IB context configure structure.

Add configuration structure for port (ethdev). This structure contains
all configurations coming from devargs which oriented to port. It is a
field of mlx5_priv structure, and is updated in spawn function for each
port.

From: Michael Baum @ 2022-01-27 15:39 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
MLX5 common driver supports probing again in two scenarios:
- Add new driver under existing device. common probe function gets
it in devargs, then calls the requested driver's probe function
(regardless of the driver's own support in probing again) with the
existing device as parameter.
- Transfer the probing again support of the drivers themselves
(currently only net). In this scenario, the existing device is sent
as a parameter to the existing driver's probe too.
In both cases it gets a new set of arguments that do not necessarily
match the configured arguments in the existing device.
Some of the arguments belong to the configuration of the existing
device, so they can't be updated in the probing again. On the other
hand, there are arguments that belong to a specific driver or specific
port and might get a new value in the probing again.
The user might generate any argument he wants in probing again, but when
he generates arguments belonging to the common device configuration, it
does not affect.
This patch adds an explicit check for the devargs belonging to the
common device configuration. If there is no match to the existing
configuration, it returns an error.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Improve the devargs handling in two aspects:
- Parse the devargs string only once.
- Return error and report for unknown keys.
The common driver parses once the devargs string into a dictionary, then
provides it to all the drivers' probe. Each driver updates within it
which keys it has used, then common driver receives the updated
dictionary and reports about unknown devargs.

v2: rebase + fix coverity issue.
These patches rearrange the management of the devargs on two different
levels.
The first splits the net driver's devargs into two categories,
device-dependent devargs and port-dependent devargs.
Arguments that depend on the device are updated once in the creation of
the shared device context structure, and do not change even if the user
has sent new devargs in the probe again. In contrast, the arguments that
depend on the port are updated separately for each port.
The second layer deals with the parsing of devargs in the common driver.
The common driver once parses the devargs into a dictionary, then sends
it to all the drivers that will use it during the their probing. Each
driver updates within dictionary which keys it has used, then the common
driver checks the updated dictionary and reports about unknown devargs.

The MLX5 net driver supports "probe again". In probing again, it
creates a new ethdev under an existing infiniband device context.
Sibling devices sharing infiniband device context should have compatible
configurations, so some of the devargs given in the probe again, the
ones that are mainly relevant to the sharing device context are sent to
the mlx5_dev_check_sibling_config function which makes sure that they
compatible its siblings.
However, the arguments are adjusted according to the capability of the
device, and the function compares the arguments of the probe again
before the adjustment with the arguments of the siblings after the
adjustment. A user who sends the same values to all siblings may fail in
this comparison if he requested something that the device does not
support and adjusted.
This patch moves the call to the mlx5_dev_check_sibling_config function
after the relevant adjustments.
Fixes: 92d5dd483450 ("net/mlx5: check sibling device configurations mismatch")
Fixes: 2d241515ebaf ("net/mlx5: add devarg for extensive metadata support")

In "dv_xmeta_en" devarg there is an option of dv_xmeta_en=3 which
engages tunnel offload mode. In E-Switch configuration, that mode
implicitly activates dv_xmeta_en=1.
The update according to E-switch support is done immediately after the
first parsing of the devargs, but there is another adjustment later.
This patch moves the adjustment after the second parsing.
Fixes: 4ec6360de37d ("net/mlx5: implement tunnel offload")

The ASO connection tracking structure is initialized once for sharing
device context.
Its release takes place in the close function which is called for each
ethdev individually. i.e. when there is more than one ethdev under the
same sharing device context, it will be destroyed when one of them is
closed. If the other wants to use it later, it may cause it to crash.
In addition, the creation of this structure is performed in the spawn
function. if one of the creations of the objects following it fails, it
is supposed to be destroyed but this does not happen.
This patch moves its release to the sharing device context free function
and thus solves both problems.

The mlx5_alloc_shared_dev_ctx() function has a local variable named
"err" which contains the errno value in case of failure.
When functions called by this function are failed, this variable is
updated with their return value (that should be a positive errno value).
However, some functions doesn't update errno value by themselves or
return negative errno value. If one of them fails, the "err" variable
contains negative value what cause to assertion failure.
This patch updates all functions uses by mlx5_alloc_shared_dev_ctx()
function to update rte_errno and take this value instead of "err" value.

In mlx5_ethdev.c file are implemented those 4 functions:
- mlx5_dev_infos_get
- mlx5_fw_version_get
- mlx5_dev_set_mtu
- mlx5_hairpin_cap_get
In mlx5.h file they are declared twice. First time under mlx5.c file and
second time under mlx5_ethdev.c file.
This patch removes the redundant declaration.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The device arguments are parsed and updated twice during spawning. First
time before creating the share device context, and again later after
updating a default value to one of the arguments.
This patch consolidates them into one parsing and updates the default
values before it.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The HCA attribute structure is field of net configure structure.
It is also field of common configure structure.
There is no need for this duplication, because there is a reference to
the common structure from within the net structures.
This patch removes it from net configure structure and uses the common
config structure instead.

From: Michael Baum @ 2022-02-14 9:34 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The sharing device context structure has a field named "devx" which
indicates if DevX is supported.
The common configure stracture has also field named "devx" with the same
meaning.
There is no need for this duplication, because there is a reference to
the common structure from within the sharing device context structure.
This patch removes it from sharing device context structure and uses the
common config structure instead.

To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
The sharing device context structure has a field named "device_attr"
which s filled by mlx5_os_get_dev_attr() function.
The spawn function calls mlx5_os_get_dev_attr() again and save it to
local variable identical to "device_attr" field.
There is no need for this duplication, because there is a reference to
the sharing device context structure from spawn function.
This patch removes the local "device_attr" from spawn function, and uses
the context's field instead.

The mlx5_flow_counter_mode_config function exists for both Linux and
Windows with the same name and content.
This patch moves its implementation to the folder shared between the
operating systems, removing the duplication.

This patch adds in SH structure a flag which indicates whether is
E-Switch mode.
When configure "dv_esw_en" from devargs, it is enabled only when is
E-switch mode. So, since dv_esw_en has been configure, it is enough to
check if "dv_esw_en" is valid.
This patch also removes E-Switch mode check when "dv_esw_en" is checked
too.

Rearrange the mlx5_os_get_dev_attr() function in such a way that it
first executes the queries and only then updates the fields.

From: Michael Baum @ 2022-02-14 9:35 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Move all device configure to be performed by mlx5_os_cap_config()
function instead of the spawn function.
In addition move all relevant fields from mlx5_dev_config structure to
mlx5_dev_cap.

From: Michael Baum @ 2022-02-14 9:35 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Add configuration structure for shared device context. This structure
contains all configurations coming from devargs which oriented to
device. It is a field of shared device context (SH) structure, and is
updated once in mlx5_alloc_shared_dev_ctx() function.
This structure cannot be changed when probing again, so add function to
prevent it. The mlx5_probe_again_args_validate() function creates a
temporary IB context configure structure according to new devargs
attached in probing again, then checks the match between the temporary
structure and the existing IB context configure structure.

From: Michael Baum @ 2022-02-14 9:35 UTC (permalink / raw)
To: dev; +Cc: Matan Azrad, Raslan Darawsheh, Viacheslav Ovsiienko
Add configuration structure for port (ethdev). This structure contains
all configurations coming from devargs which oriented to port. It is a
field of mlx5_priv structure, and is updated in spawn function for each
port.

MLX5 common driver supports probing again in two scenarios:
- Add new driver under existing device. common probe function gets
it in devargs, then calls the requested driver's probe function
(regardless of the driver's own support in probing again) with the
existing device as parameter.
- Transfer the probing again support of the drivers themselves
(currently only net). In this scenario, the existing device is sent
as a parameter to the existing driver's probe too.
In both cases it gets a new set of arguments that do not necessarily
match the configured arguments in the existing device.
Some of the arguments belong to the configuration of the existing
device, so they can't be updated in the probing again. On the other
hand, there are arguments that belong to a specific driver or specific
port and might get a new value in the probing again.
The user might generate any argument he wants in probing again, but when
he generates arguments belonging to the common device configuration, it
does not affect.
This patch adds an explicit check for the devargs belonging to the
common device configuration. If there is no match to the existing
configuration, it returns an error.

Improve the devargs handling in two aspects:
- Parse the devargs string only once.
- Return error and report for unknown keys.
The common driver parses once the devargs string into a dictionary, then
provides it to all the drivers' probe. Each driver updates within it
which keys it has used, then common driver receives the updated
dictionary and reports about unknown devargs.

> The first splits the net driver's devargs into two categories,
> device-dependent devargs and port-dependent devargs.
> Arguments that depend on the device are updated once in the creation of

> has sent new devargs in the probe again. In contrast, the arguments that
> depend on the port are updated separately for each port.
>
> The second layer deals with the parsing of devargs in the common driver.
> The common driver once parses the devargs into a dictionary, then sends
> it to all the drivers that will use it during the their probing. Each
> driver updates within dictionary which keys it has used, then the common
> driver checks the updated dictionary and reports about unknown devargs.
