[PATCH] drm/powerplay: Fix Vega20 Average Power value v4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SMU changed reading from CurrSocketPower to AverageSocketPower, so
reflect this accordingly. This fixes the issue where Average Power
Consumption was being reported as 0 from SMU 40.46-onward

v2: Fixed headline prefix
v3: Add check for SMU version for proper compatibility
v4: Style fix
