drm/amd: Add detailed GFXOFF stats to debugfs

2022-08-16T22:17:31Z

Add debugfs interface to log GFXOFF statistics: - Read amdgpu_gfxoff_count to get the total GFXOFF entry count at the time of query since system power-up - Write 1 to amdgpu_gfxoff_residency to start logging, and 0 to stop. Read it to get average GFXOFF residency % multiplied by 100 during the last logging interval. Both features are designed to be keep the values persistent between suspends.

amdgpu/pm: Implement new API function "emit" that accepts buffer base and write offset

(v3) Rewrote patchset to order patches as (API, hw impl, usecase) - added API for new power management function emit_clk_levels This function should duplicate the functionality of print_clk_levels, but this solution passes the buffer base and write offset down the stack. - new powerplay function emit_clock_levels, implemented by smu_emit_ppclk_levels() This function parallels the implementation of smu_print_ppclk_levels and calls emit_clk_levels, and allows the returns of errors - new helper function smu_convert_to_smuclk called by smu_print_ppclk_levels and smu_emit_ppclk_levels Signed-off-by: Darren Powell Reviewed-By: Evan Quan Signed-off-by: Alex Deucher
