During post-migration recovery, only MMIO communication to GuC is allowed. The VF KMD needs to use that channel to ask for the new provisioning, which includes a new GGTT range assigned to the VF. v2: query config only instead of handshake; no need to get pm ref as it's now kept through whole recovery (Michal) v3: switched names of 'err' and 'ret' (Michal) Signed-off-by: Tomasz Lis <tomasz.lis@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241104213449.1455694-5-tomasz.lis@intel.com Signed-off-by: Michal Wajdeczko <michal.wajdeczko@intel.com>
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 reStructuredText 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.
