drm/amd/pm: initialize variable

In some cases data is not set.  Initialize to 0 and flag not setting
data as an error with the existing check.

amdgpu/pm: set pp_dpm_dcefclk to readonly on NAVI10 and newer gpus

2021-04-29T03:56:14+00:00

v2 : change condition to apply to all chips after NAVI10

Writing to dcefclk causes the gpu to become unresponsive, and requires a reboot.
Patch prevents user from successfully writing to file pp_dpm_dcefclk on parts
NAVI10 and newer, and gives better user feedback that this operation is not allowed.

drm/amdgpu/pm: bail on sysfs/debugfs queries during platform suspend

2021-04-09T20:43:35+00:00

The GPU is in the process of being shutdown.  Spurious queries during
suspend and resume can put the SMU into a bad state.  Runtime PM is
handled dynamically so we check if we are in non-runtime suspend.
