Hi Dave & Daniel,

Sorry for the big PR in advance. Had the summer vacations and did not
notice until tool late how many patches were in already before leaving.

As requested, there is a lot of refactoring to increase the use of TTM
allocator and prep for DRM scheduler. Note that at times the patches trade
simplicity for performance and revert optimizations not seen as critical.
So some performance regressions are expected.

As an example is dropping of faster GPU relocation path for older platforms,
which should be mitigated by updating to the latest UMD versions to regain
the perf.

This PR drops various bits of uAPI where userspace has dropped the ball after reviews
have been completed on both sides (Thanks Jason for doing the due-diligence!). [1]
Due to the complexity of tracing back who used what, I think we could do better in the
future to avoid such situations to begin with. See below for my suggestion [2].

In addition to the refactoring and uAPI cleanup there is preliminay code for
ADL-P/XeHP and DG2 platforms. Fixes for ADL-S and removal of CNL code.
A couple of fixes that have been Cc: stable already. Removing unnecessary
workarounds per stepping and adding missing for Gen12 iGFX.

I915_MMAP_OFFSET_FIXED is also added to to align with the static/fixed caching
mode per BO instead of per-mapping mode (for dGFX only). There is GuC firmware
interface update and backend code major rework that unblock enabling GuC on Gen11
(not on by default). Then there is the addition of the GuCRC power management
feature which can be enabled for Gen12+ when submission is enabled.

Then there is finally the drm-next backmerge and 3 topic branch merges.

I think that is mostly all. I tried to summarize much in the tag description so
it should hopefully not be horribly long...

Regards, Joonas

[1] Given that Jason is only human and there is no way to automate this analysis, we
may have to bring something back as fixes if we find breakage (like with the MMAP IOCTL).

[2] As we first require to merge the kernel code, should we introduce some further rules
that the userspace has to land their code before the final kernel version release? If
that is not followed through, we would neuter the new uAPI with as small patch as possible
in the final release candidate and then remove it in next release. Thoughts?

drm-intel-gt-next-2021-08-06-1:

UAPI Changes:

- Add I915_MMAP_OFFSET_FIXED

  On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
  type. On devices without local memory, this caching mode is invalid.

  As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
  be used, depending on the object placement on creation. WB will be used
  when the object can only exist in system memory, WC otherwise.

  Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888

- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms

  Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
  still to sunset the IOCTL even for integrated and require using mmap_offset.

- Reject caching/set_domain IOCTLs on discrete

  Expected to become immutable property of the BO

- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12

  Rationale (for both): Allow less dynamic changes to the context to simplify
  the implementation and avoid user shooting theirselves in the foot.

- Drop I915_CONTEXT_PARAM_RINGSIZE

  Userspace PR for compute-driver has not been merged

- Drop I915_CONTEXT_PARAM_NO_ZEROMAP

  Userspace PR for libdrm / Beignet was never landed

- Drop CONTEXT_CLONE API

  Userspace PR for Mesa was never landed

- Drop getparam support for I915_CONTEXT_PARAM_ENGINES

  Only existed for symmetry wrt. setparam, never used.

- Disallow bonding of virtual engines

  Drop the prep work, no hardware has been released needing it.

- (Implicit) Disable gpu relocations

  Media userspace was the last userspace to still use them. They
  have converted so performance can be regained with an update.

There is also addition of I915_USERPTR_PROBE with userspace changes in:

> - Reinstate the mmap ioctl for (already released) integrated Gen12 platforms
> 
>   Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
>   still to sunset the IOCTL even for integrated and require using mmap_offset.
> 
> - Reject caching/set_domain IOCTLs on discrete
> 
>   Expected to become immutable property of the BO
> 
> - Disallow changing context parameters after first use on Gen12 and earlier
> - Require setting context parameters at creation on platforms after Gen12
> 
>   Rationale (for both): Allow less dynamic changes to the context to simplify
>   the implementation and avoid user shooting theirselves in the foot.
