Invalidate instruction and State cache bit using INDIRECT_CTX on every gpu context switch for gen12. The goal of this workaround is to actually perform an explicit invalidation of that cache (by re-writing the register) during every GPU context switch, which is accomplished via a "workaround batchbuffer" that's attached to the context via INDIRECT_CTX. (Matt Roper) Please refer [1] for more reviews and comment on the same patch [1] https://patchwork.freedesktop.org/series/123377/ v2: - Remove extra parentheses from the condition (Lucas) - Align spacing and new line (Lucas) v3: - Fix commit message. v4: - Only Gen12 changes are kept and Remove DG2+ condition (Matt Roper) - Fix the commit message for r-b (Matt Roper) - Rename the register bit in define v5: - Move out this workaround from golden context init (Matt Roper) - Use INDIRECT_CTX to set bit on each GPU context switch (Matt Roper) v6: - Change IP Version base condition for Gen12 (Matt Roper) - Made imperative form of commit version messages (Suraj) - s/Added/Add in patch header (Suraj) v7: - In version descriptions s/Ropper/Roper (Matt Atwood) BSpec: 11354 Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Suraj Kandpal <suraj.kandpal@intel.com> Cc: Matt Atwood <matthew.s.atwood@intel.com> Signed-off-by: Dnyaneshwar Bhadane <dnyaneshwar.bhadane@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230914202000.1069884-1-dnyaneshwar.bhadane@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.
