As part of the recommended tuning setting, whitelist COMMON_SLICE_CHICKEN1 for MTL/ARL and DG2. The UMD will selectively enable or disable specific bits of the register based on the type of workload and its requirements. v2: Remove the KMD par of enabling specific bits(Matt R) Signed-off-by: Dnyaneshwar Bhadane <dnyaneshwar.bhadane@intel.com> --- drivers/gpu/drm/i915/gt/intel_workarounds.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
