Flush the g2h worker explicitly if TLB timeout happens which is observed on LNL and that points to the recent scheduling issue with E-cores on LNL. This is similar to the recent fix: commite515272338("drm/xe/guc/ct: Flush g2h worker in case of g2h response timeout") and should be removed once there is E core scheduling fix. v2: Add platform check(Himal) v3: Remove gfx platform check as the issue related to cpu platform(John) Use the common WA macro(John) and print when the flush resolves timeout(Matt B) v4: Remove the resolves log and do the flush before taking pending_lock(Matt A) Cc: Badal Nilawar <badal.nilawar@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: stable@vger.kernel.org # v6.11+ Link: https://gitlab.freedesktop.org/drm/xe/kernel/-/issues/2687 Signed-off-by: Nirmoy Das <nirmoy.das@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241029120117.449694-3-nirmoy.das@intel.com Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> (cherry picked from commite1f6fa5566) Signed-off-by: Lucas De Marchi <lucas.demarchi@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.
