drm/amd/display: remove unused average_render_time_in_us and i variables

2023-04-11T22:03:22Z

clang with W=1 reports drivers/gpu/drm/amd/amdgpu/../display/modules/freesync/freesync.c:1132:15: error: variable 'average_render_time_in_us' set but not used [-Werror,-Wunused-but-set-variable] unsigned int average_render_time_in_us = 0; ^ This variable is not used so remove it, which caused i to be unused so remove that as well.

drm/amd/display: Firmware assisted MCLK switch and FS

2022-06-15T01:38:41Z

[WHY] Memory clock switching has great potential for power savings. [HOW] The driver code was modified to notify the DMCUB firmware that it should stretch the vertical blank of frames when a memory clock switch is about to start so that no blackouts happen on the screen due to unavailability of the frame buffer. The driver logic to determine when such firmware assisted strategy can be initiated is also implemented and consists on checking prerequisites of the feature.
