[Intel-gfx] [PATCH 8/9] drm/i915/gt: Expose per-gt RPS defaults in sysfs
Create a gt/gtN/.defaults directory (similar to
engine//.defaults) to expose default parameter values for each
gt in sysfs. Populate the .defaults directory with RPS parameter default
values in order to allow userspace to revert to default values when needed.
This patch adds the following sysfs files to gt/gtN/.defaults:
* default_min_freq_mhz
* default_max_freq_mhz
* default_boost_freq_mhz
