2021-06-10drm/amd/pm: Add u64 throttler status field to gpu_metricsGraham Sider
This patch set adds support for a new ASIC independant u64 throttler status field (indep_throttle_status). Piggybacks off the gpu_metrics_v1_3 bump and similarly bumps gpu_metrics_v2 version (to v2_2) to add field.

Command guide: echo "s level value" > pp_od_clk_voltage "s" - set the sclk frequency "level" - 0 or 1, "0" represents the min value, "1" represents the max value "value" - the target value of sclk frequency, it should be limited in the safe range echo "r" > pp_od_clk_voltage "r" - reset the sclk frequency, restore the default value echo "c" > pp_od_clk_voltage "c" - commit the min and max value of sclk frequency to the system only after the commit command, the setting target values by "s" command will take effect Example: 1) check the default sclk frequency $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 600Mhz OD_RANGE: SCLK: 200MHz 600MHz 2) use "s" -- set command to configure the min or max sclk frequency $ echo "s 0 300" > pp_od_clk_voltage $ echo "s 1 500" > pp_od_clk_voltage $ echo "c" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 300Mhz 1: 500Mhz OD_RANGE: SCLK: 200MHz 600MHz 3) use "r" -- reset command to restore the min and max sclk frequency $ echo "r" > pp_od_clk_voltage $ echo "c" > pp_od_clk_voltage $ cat pp_od_clk_voltage OD_SCLK: 0: 200Mhz 1: 600Mhz OD_RANGE: SCLK: 200MHz 600MHz v2: modify the description of reset command usage - need to do "commit" after set the restore command Signed-off-by: Xiaomeng Hou <Xiaomeng.Hou@amd.com> Reviewed-by: Huang Rui <ray.huang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
