[Intel-gfx] [RFC PATCH 00/97] Basic GuC submission support in the i915

[Matthew Brost <matthew.brost@intel.com>]

Basic GuC submission support. This is the first bullet point in the
upstreaming plan covered in the following RFC [1].

At a very high level the GuC is a piece of firmware which sits between
the i915 and the GPU. It offloads some of the scheduling of contexts
from the i915 and programs the GPU to submit contexts. The i915
communicates with the GuC and the GuC communicates with the GPU.

GuC submission will be disabled by default on all current upstream
platforms behind a module parameter - enable_guc. A value of 3 will
enable submission and HuC loading via the GuC. GuC submission should
work on all gen11+ platforms assuming the GuC firmware is present.

This is a huge series and it is completely unrealistic to merge all of
these patches at once. Fortunately I believe we can break down the
series into different merges:

1. Merge Chris Wilson's patches. These have already been reviewed
upstream and I fully agree with these patches as a precursor to GuC
submission.

2. Update to GuC 60.1.2. These are largely Michal's patches.

3. Turn on GuC/HuC auto mode by default.

4. Additional patches needed to support GuC submission. This is any
patch not covered by 1-3 in the first 34 patches. e.g. 'Engine relative
MMIO'

5. GuC submission support. Patches number 35+. These all don't have to
merge at once though as we don't actually allow GuC submission until the
last patch of this series.
