c941e9fe9c drm/amd/pm: Add support for reset completion on aldebaran
v1: On aldebaran, after hardware context restore, another handshake
needs to happen with PMFW so that reset recovery is complete from
PMFW side. Treat this as RESET_COMPLETE event for aldebaran.

d2ae842d24 drm/amdgpu/pm: bail on sysfs/debugfs queries during platform suspend
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.

65ec7c08c1 drm/amd/pm: Enable user min/max gfxclk on aldebaran
Aldebaran has fine grained DPM for GFXCLK. Instead of a discrete level,
user can specify a min/max range of GFXCLK for any profiling/tuning
purpose.This option is available only in manual performance level mode.
Select "manual" as power_dpm_force_performance_level and specify the
min/max range using pp_dpm_sclk sysfs node. User cannot specify a min/max
range outside of the default min/max range of the ASIC. If specified
outside the range, values will be bound by the default min/max range.

Ex: To use gfxclk min = 600MHz and max = 900MHz

echo manual > /sys/bus/pci/devices/.../power_dpm_force_performance_level

6be6424684 drm/amd/pm: Enable performance determinism on aldebaran
Performance Determinism is a new mode in Aldebaran where PMFW tries to
maintain sustained performance level. It can be enabled on a per-die
basis on aldebaran. To guarantee that it remains within the power cap,
a max GFX frequency needs to be specified in this mode. A new
power_dpm_force_performance_level, "perf_determinism", is defined to enable
this mode in amdgpu. The max frequency (in MHz) can be specified through
pp_dpm_sclk. The mode will be disabled once any other performance level
is chosen.

Ex: To enable perf determinism at 900Mhz max gfx clock

echo perf_determinism > /sys/bus/pci/devices/.../power_dpm_force_performance_level
echo max 900 > /sys/bus/pci/devices/.../pp_dpm_sclk
