If testing confirms this: Acked-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> You only may need to change that INTEL_GEN to GRAPHICS_VER since I think that's the new thing now.

EHL and JSL are also observing requirement for 80ns interval for CTX_TIMESTAMP thus extending it to GEN11. Signed-off-by: Tejas Upadhyay <tejaskumarx.surendrakumar.upadhyay@intel.com> --- drivers/gpu/drm/i915/gt/selftest_engine_pm.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
