drm/amd/pm: add support for hwmon control of slow and fast PPT limit on vangogh

2021-02-09T20:29:28+00:00

Implement hwmon API for reading/setting slow and fast PPT limit.

APU power is managed to system-level requirements through the PPT
(package power tracking) feature. PPT is intended to limit power to the
requirements of the power source and could be dynamically updated to
maximize APU performance within the system power budget.

Here FAST_PPT_LIMIT manages the ~10 ms moving average of APU power,
while SLOW_PPT_LIMIT manages the configurable, thermally significant
moving average of APU power (default ~5000 ms).

User could read slow/fast ppt limit using command "cat power*_cap" or
"sensors" in the hwmon device directory. User could adjust values of
slow/fast ppt limit as needed depending on workloads through command
"echo ## > power*_cap".

Example:
$ echo 15000000 > power1_cap
$ echo 18000000 > power2_cap
$ sensors
amdgpu-pci-0300
Adapter: PCI adapter
slowPPT:     9.04W (cap = 15.00 W)
fastPPT:     9.04W (cap = 18.00 W)

v2: align with existing interfaces for the getting/setting of PPT
    limits. Encode the upper 8 bits of limit value to distinguish
    slow and fast power limit type.

drm/amd/pm: modify the power limit level parameter from bool to enum type

2021-02-09T20:29:22+00:00

The original smu_get_power_limit callback accepts the power limit level
parameter as bool which limits to max and current. For possible needs to
retrieve other level like min, extend the parameter type using enum.

drm/amdgpu/swsmu: use percent rather than rpm for manual fan control (v2)

2021-02-01T16:51:47+00:00

On some boards the rpm interface apparently does not work at all
leading to the fan not spinning or spinning at strange speeds.
Both interfaces work properly on the boards I have.
Let's try and use the percent interface instead.

v2: rebase on revert

On some boards the rpm interface apparently does not work at all

Revert this for now to fix 5.10, 5.11.  The follow on patch
fixes this properly for 5.12.

drm/amd/pm: store and reinstate swsmu user power configurations

2021-01-25T22:47:00+00:00

store swsmu user power configurations which include
power limit, clock frequencies, fan speed and fan mode
on suspend and reinstate on resume.

V2: Addressed Lijo's review comments
     added a function to set clock interdependencies
     add check on fan control mode to reapply fan speed

V3: Addressed review comments from Alex
     moved store logic and reinstate function call into swSMU

V4: added a logic to keep off storing configurations in suspend

V5: Addressed review comments from Lijo
     add a restore flag
     give restore priority to mclk comparing fclk and socclk
