Samuel Pitoiset d6c29695e6 drm/amdgpu: implement read_sensor() for pre-powerplay chips
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

Tom St Denis 9f8df7d71e drm/amd/amdgpu: Update read_sensor calls to have size parameter (v3)
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

Eric Huang 34bb2734d1 drm/amd/amdgpu: add power profile sysfs entry
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.
