1) Few cleanups 2) Dynamic completion EQs The driver creates completion EQs for all vectors directly on driver load, even if those EQs will not be utilized later on. To allow more flexibility in managing completion EQs and to reduce the memory overhead of driver load, this series will adjust completion EQs creation to be dynamic. Meaning, completion EQs will be created only when needed. Patch #1 introduces a counter for tracking the current number of completion EQs. Patches #2-6 refactor the existing infrastructure of managing completion EQs and completion IRQs to be compatible with per-vector allocation/release requests. Patches #7-8 modify the CPU-to-IRQ affinity calculation to be resilient in case the affinity is requested but completion IRQ is not allocated yet. Patch #9 function rename. Patch #10 handles the corner case of SF performing an IRQ request when no SF IRQ pool is found, and no PF IRQ exists for the same vector. Patch #11 modify driver to use dynamically allocate completion EQs. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEGhZs6bAKwk/OTgTpSD+KveBX+j4FAmTRL7AACgkQSD+KveBX +j69VggA0+5AO3WkMOy6055/HQoSiO/UqdSwyZhedu9nUFtQmmybIkkqghebTZgO +tLMjSzPjkhtnY70Fybb+MAH2QiOVO7MxMvg99punmhpB1RBYSo7mg2WG/la55A1 E+ocN6uL0Jv2HUXbECSM8OhGOOf6wJNXRk9kzc6AJWsmun356HveaW8n8hp0JCJr hnqbyPZJjLAYlcXH9jjvseCW7tHZH30WPAoYqVXRMao8LPbvjCWlinw3gntmet0f 746oxkNapZrHj+lHHrmGRr23+pOWZGW0nt8cxJlXHd0yDP116RDDf64gcop92AYX YWVe8whSb2yp6FcscNtb1Vt5vw/c9w== =e5aZ -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2023-08-07' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2023-08-07 1) Few cleanups 2) Dynamic completion EQs The driver creates completion EQs for all vectors directly on driver load, even if those EQs will not be utilized later on.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
