Evan Quan 3e38b634f9 drm/amd/pm: introduce a new set of OD interfaces
There will be multiple interfaces(sysfs files) exposed with each representing
a single OD functionality. And all those interface will be arranged in a tree
liked hierarchy with the top dir as "gpu_od". Meanwhile all functionalities
for the same component will be arranged under the same directory.

YiPeng Chai a6ad27cec5 drm/amd/pm: Remove redundant check condition
V3:
[Why]:
  Since ASICs using smu v13_0_2 have called smu
.suspend before calling amdgpu_pm_sysfs_fini,
pm.dpm_enabled was already set to 0 when smu
.suspend was called. This makes it impossible
to delete all pm sys nodes.

[How]:
  Since all functions in amdgpu_pm_sysfs_fini
have their own condition checks, so the first
conditional check in amdgpu_pm_sysfs_fini can
be removed.

Kent Russell 60044748f2 drm/amdgpu: Use switch case for unique_id
To ease readability, use switch to set unique_id as supported for the
supported IP_VERSIONs, and set it to unsupported by default for all
other ASICs.
This makes it easier to add IP_VERSIONs later on, and makes it obvious
that it is not supported by default, instead of the current logic that
assumes that it is supported unless it is not one of the specified
IP_VERSIONs.

v2: Rebase onto previous IP_VERSION change

Alex Deucher 8cda7a4f96 drm/amdgpu/UAPI: add new CTX OP to get/set stable pstates
Add a new CTX ioctl operation to set stable pstates for profiling.
When creating traces for tools like RGP or using SPM or doing
performance profiling, it's required to enable a special
stable profiling power state on the GPU.  These profiling
states set fixed clocks and disable certain other power
features like powergating which may impact the results.

Historically, these profiling pstates were enabled via sysfs,
but this adds an interface to enable it via the CTX ioctl
from the application.  Since the power state is global
only one application can set it at a time, so if multiple
applications try and use it only the first will get it,
the ioctl will return -EBUSY for others.  The sysfs interface
will override whatever has been set by this interface.

Lijo Lazar 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
