[PATCH v1 0/3] Additional queue stats

[PATCH v1 0/3] Additional queue stats

[Nicolas Chautru]

These series include introducing a new paramter in the queue stat
which can be used to monitor the number of available enqueue
still possible. 
The acc PMD is then refactored to use a set of common function
to update several queue status parameters including the new one.
The application is also updated.
Thanks
Nic

[PATCH v1 1/3] bbdev: new queue stat for available enqueue depth

[Nicolas Chautru]

Capturing additional queue stats counter for the
depth of enqueue batch still available on the given
queue. This can help application to monitor that depth
at run time.

Adding field is an ABI change and will have to wait until 24.11 release

Doesn't this break the ABI?

RE: [PATCH v1 1/3] bbdev: new queue stat for available enqueue depth

[Chautru, Nicolas]

Hi Stephen, 

It is not strictly ABI compatible since the size of the structure increases, hence only updating for 24.11.

I think it needs to be documented in the ABI change section.

RE: [PATCH v1 1/3] bbdev: new queue stat for available enqueue depth

[Chautru, Nicolas]

Hi Maxime, 

The branch origin/next-baseband-for-main doesn’t have yet the updates from main, such as the ./doc/rel_notes for 24.11. 
Can you refresh this? Or let me know how best to proceed.
Thanks, 
Nic
