| H A D | guc_actions_slpc_abi.h | 26be7cd8 Wed May 25 08:19:17 CDT 2022 Ashutosh Dixit <ashutosh.dixit@intel.com> drm/i915/gt: Add media freq factor to per-gt sysfs
Expose new sysfs to program and retrieve media freq factor. Factor values
of 0 (dynamic), 0.5 and 1.0 are supported via a u8.8 fixed point
representation (corresponding to integer values of 0, 128 and 256
respectively).
Media freq factor is converted to media_ratio_mode for GuC. It is
programmed into GuC using H2G SLPC interface. It is retrieved from GuC
through a register read. A cached media_ratio_mode is maintained to
preserve set values across GuC resets.
This patch adds the following sysfs files to gt/gtN sysfs:
* media_freq_factor
* media_freq_factor.scale
v2: Minor wording change in drm_warn (Tvrtko)
