Some WAs touch registers that get saved/restored together with the logical context. Make this very explicit by renaming a few things in the code. v2: - Improved naming - Rebased v3: Also rename I915_MAX_CTX_WA_REGS Signed-off-by: Oscar Mateo <oscar.mateo@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> --- drivers/gpu/drm/i915/i915_debugfs.c | 10 +- drivers/gpu/drm/i915/i915_drv.h | 7 +- drivers/gpu/drm/i915/intel_workarounds.c | 232 +++++++++++++++---------------- 3 files changed, 125 insertions(+), 124 deletions(-)
