Subject: drm/xe: Fake pulling gt->info.engine_mask from hwconfig blob
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=da34c2cf85a4739d4e2b1b5515a0fbc8f8e60358;p=linux.git

drm/xe: Fake pulling gt->info.engine_mask from hwconfig blob

The blob doesn't fully support this yet, so fake for now to ensure our
driver load order is correct.

Once the blob supports pulling gt->info.engine_mask from the blob, this
patch can be removed.
