[PATCH 000/138] The new SW SMU driver of amdgpu

[Huang Rui]

Hi all,

The series of patches are to implement a new SW SMU driver for future asics.

Background:
The powerplay driver will be retired. The final version is for vega20 with
SMU11. However, the future asic will use the new swSMU framework to implement as
well. Here is the first version of new sw smu driver that is basing on vega20.

Purpose: 
We would like to do re-arch for linux power codes to use a new sw SMU ip block
for future asics. We hope to write a simple and readable framework for Linux. 

Currently, the default path is still with powerplay on vega20. So far we don’t
plan to switch default path to new swSMU design for vega20. And we can use the
module parameter amdgpu_dpm to switch it to new SW SMU design (modprobe amdgpu
dpm=1).

Development Items:
- Setup new SMU IP block skeleton.
- Implement SMC firmware loading function.
- Implement SMC table data structure. 
- Implement SMU v11 indirect register (MP1) read/write and SMC message sending
  helpers.
- Implement SMU v11 SMC table initialization (read from vbios, parse, populate,
  and write back to smc).
- Implement SMU v11 memory pool location function.
- Enable DPM feature for SMU v11 and implement DPM control callback function.
- Enable interfaces for starting tools.
- Implement SMU v11 power control and power containment functions.
- Implement and enable SMU v11 thermal/fan control function.
- Implement SMU interfaces placeholder for DC, VCN, and KFD driver. 
- Enable and align sys interface in the amdgpu_pm.c.

So far, Kevin, Likun, Jack, and I have enabled features such as dpm, od,
thermal, and etc. with new sw smu driver. (Thanks to Kevin, Likun and Jack's
great effort!)

Any comments are warm for us.

Thanks & Best Regards!
Ray
