Invalidating the GuC TLBs while GuC is not loaded does not have negative consequences, so if we're starting the driver with GuC enabled we can use the GGTT invalidation function from the get-go, instead of switching to it when we initialize the GuC objects. In MTL, this fixes and issue where we try to overwrite the invalidation function twice (once for each GuC), due to the GGTT being shared between the primary and media GTs Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Radhakrishna Sripada <radhakrishna.sripada@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Aravind Iddamsetty <aravind.iddamsetty@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221110175823.3867135-1-daniele.ceraolospurio@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 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.
