2017-03-29drm/amd/amdgpu: Update read_sensor calls to have size parameter (v3)Tom St Denis
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.

2017-03-29drm/amd/amdgpu: add power profile sysfs entryEric Huang
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.

2016-03-02drm/amdgpu/pm: update current crtc info after setting the powerstateAlex Deucher
On CI, we need to see if the number of crtcs changes to determine whether or not we need to upload the mclk table again. In practice we don't currently upload the mclk table again after the initial load. The only reason you would would be to add new states, e.g., for arbitrary mclk setting which is not currently supported.
