Subject: drm/xe: Mark BCS engines as belonging to the GT forcewake domain
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8954033df47864e255aa0c5a3fc10a60f73325af;p=thirdparty%2Fkernel%2Flinux.git

drm/xe: Mark BCS engines as belonging to the GT forcewake domain

On all platforms supported by the Xe driver, BCS engines are part of the
GT forcewake domain, not the RENDER domain.  Fix the engine list
definition to match the spec.  This mistake didn't really cause any
real problems because the forcewake domain here was only used in a
couple assertions that aren't really necessary and included in the
information dumped during error capture.
