From fb251a72d630950fb1a6f4cccff99bffe5aece8b Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 5 Mar 2019 18:03:31 +0000 Subject: [PATCH] drm/i915/gtt: Mark ALL_ENGINES as dirty on ppGTT modification Small simplification to set all bits in the dirty mask rather than lookup the exact mask of populated engines. The bits for the engines that do not exist are unused and so can safely set and then ignored.
