drm/amdgpu: implement read_sensor() for pre-powerplay chips

2017-03-30T03:53:03Z

Add the GPU temperature, the shader clock and eventually the memory clock (as well as the GPU load on CI). The main goal is to expose this info to the userspace like Radeon. v2: - add AMDGPU_PP_SENSOR_GPU_LOAD on CI - update the commit description Signed-off-by: Samuel Pitoiset Signed-off-by: Alex Deucher

drm/amd/amdgpu: Update read_sensor calls to have size parameter (v3)

2017-03-30T03:52:59Z

This update allows sensors to return more than 1 value and indicates to the caller how many bytes are written. The debugfs interface has been updated to handle reading all of the values. Simply seek to the enum value (multiplied by 4) and then read as many bytes as the sensor provides. (v2): Don't set size to 4 before reading GPU_POWER (v3): agd: rebase Signed-off-by: Tom St Denis Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/amdgpu: add power profile sysfs entry

2017-03-30T03:52:48Z

Add the sysfs entries pp_gfx_power_profile and pp_compute_power_profile which give user a way to set power profile through parameters minimum sclk, minimum mclk, activity threshold, up hysteresis and down hysteresis only when the entry power_dpm_force_performance_level is in default value "auto". It is read and write. Example: echo 500 800 20 0 5 > /sys/class/drm/card0/device/pp_*_power_profile cat /sys/class/drm/card0/device/pp_*_power_profile 500 800 20 0 5 Note: first parameter is sclk in MHz, second is mclk in MHz, third is activity threshold in percentage, fourth is up hysteresis in ms and fifth is down hysteresis in ms. echo set > /sys/class/drm/card0/device/pp_*_power_profile To set power profile state if it exists. echo reset > /sys/class/drm/card0/device/pp_*_power_profile To restore default state and clear previous setting.
