Create a gt/gtN/.defaults directory (similar to engine/<engine-name>/.defaults) to expose default parameter values for each gt in sysfs. This allows userspace to restore default parameter values after they may have changed. Patch 1: Creates the gt/gtN/.defaults directory Patch 2: Adds per-gt RPS defaults to gt/gtN/.defaults Patch 3: Adds media_freq_factor to gt/gtN/.defaults Cc: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx> Cc: Andi Shyti <andi.shyti@xxxxxxxxxxxxxxx> Signed-off-by: Ashutosh Dixit <ashutosh.dixit@xxxxxxxxx> Ashutosh Dixit (3): drm/i915/gt: Create gt/gtN/.defaults for per gt sysfs defaults drm/i915/gt: Expose per-gt RPS defaults in sysfs drm/i915/gt: Expose default value for media_freq_factor in per-gt sysfs drivers/gpu/drm/i915/gt/intel_gt_sysfs.c | 10 ++-- drivers/gpu/drm/i915/gt/intel_gt_sysfs.h | 6 ++ drivers/gpu/drm/i915/gt/intel_gt_sysfs_pm.c | 64 +++++++++++++++++++++ drivers/gpu/drm/i915/gt/intel_gt_types.h | 11 ++++ drivers/gpu/drm/i915/gt/intel_rps.c | 3 + drivers/gpu/drm/i915/gt/uc/intel_guc_slpc.c | 19 ++++-- 6 files changed, 103 insertions(+), 10 deletions(-) -- 2.34.1
