Use the correct engine class shift value while storing the ctx hw id. Fixes the copy+paste error from commit61d5676b55("drm/i915/perf: fix ctx_id read with GuC & ICL"). Apologies for not spotting this in the original review, the specific_ctx_id_mask is correct, only the specific_ctx_id had this problem. v2: Just use the upper 32 bits of lrc_desc (Chris) v3: If we use the lrc_desc, we must apply the ctx_id_mask too (Lionel) Fixes:61d5676b55("drm/i915/perf: fix ctx_id read with GuC & ICL") Signed-off-by: Michel Thierry <michel.thierry@intel.com> Cc: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Michel Thierry <michel.thierry@intel.com> Cc: Matthew Auld <matthew.auld@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: intel-gfx@lists.freedesktop.org Reviewed-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180604233250.609-2-michel.thierry@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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
