Semaphores are an optimization and not required for basic GuC submission to work properly. Disable until we have time to do the implementation to enable semaphores and tune them for performance. Also long direction is just to delete semaphores from the i915 so another reason to not enable these for GuC submission. This patch fixes an existing bugs where I915_ENGINE_HAS_SEMAPHORES was not honored correctly. v2: Reword commit message v3: (John H) - Add text to commit indicating this also fixing an existing bug v4: (John H) - s/bug/bugs Cc: John Harrison <john.c.harrison@intel.com> Signed-off-by: Matthew Brost <matthew.brost@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210721215101.139794-14-matthew.brost@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.
