If FW sets release_all_pages bit in MLX5_EVENT_TYPE_PAGE_REQUEST, driver shall release all pages of a given function id, with no further pages reclaim negotiation with FW nor MANAGE_PAGES commands from driver towards FW. Upon receiving this bit as part of pages reclaim event, driver will initiate release all flow, in which it will iterate and release all function's pages. As part of driver <-> FW capabilities handshake, FW will report release_all_pages max HCA cap bit, and driver will set the release_all_pages bit in HCA cap. NIC: ConnectX-4 Lx CPU: Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz Test case: Simulataniously FLR 4 VFs, and measure FW release pages by driver.

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.
