[Intel-gfx] [PATCH v3 0/5] Update AUX invalidation sequence

[Intel-gfx] [PATCH v3 0/5] Update AUX invalidation sequence

[Andi Shyti]

Hi,

as there are new hardware directives, we need a little adaptation
for the AUX invalidation sequence.

In this version we support all the engines affected by this
change.

The stable backport has some challenges because the original
patch that this series fixes has had more changes in between.

Thanks a lot Nirmoy for your review and for the fruitful discussions!

Thanks,
Andi

Changelog:
=========
v2 -> v3
 - added r-b from Nirmoy in patch 1 and 4.
 - added patch 3 which enables the ccs_flush in the control pipe for mtl+
   compute and render engines.
 - added redundant checks in patch 2 for enabling the EMIT_FLUSH flag.

v1 -> v2
 - add a clean up preliminary patch for the existing registers
 - add support for more engines
 - add the Fixes tag

Andi Shyti (3):
  drm/i915/gt: Cleanup aux invalidation registers
  drm/i915/gt: Enable the CCS_FLUSH bit in the pipe control
  drm/i915/gt: Support aux invalidation on all engines

Jonathan Cavitt (2):
  drm/i915/gt: Ensure memory quiesced before invalidation
  drm/i915/gt: Poll aux invalidation register bit on invalidation

[Intel-gfx] [PATCH v3 1/5] drm/i915/gt: Cleanup aux invalidation registers

[Andi Shyti]

Fix the 'NV' definition postfix that is supposed to be INV.

Take the chance to also order properly the registers based on
their address and call the GEN12_GFX_CCS_AUX_INV address as
GEN12_CCS_AUX_INV like all the other similar registers.

Remove also VD1, VD3 and VE1 registers that don't exist.

[Intel-gfx] [PATCH v3 3/5] drm/i915/gt: Enable the CCS_FLUSH bit in the pipe control

[Andi Shyti]

Enable the CCS_FLUSH bit 13 in the control pipe for render and
compute engines in platforms starting from Meteor Lake (BSPEC
43904 and 47112).

PIPE_CONTROL is only available for render and compute so we can skip 
this engine check.

This "flags" is applied to DWORD 1 of PIPE_CONTROL but we need this for 
DWORD 0

[Intel-gfx] [PATCH v3 4/5] drm/i915/gt: Poll aux invalidation register bit on invalidation

[Andi Shyti]

From: Jonathan Cavitt <jonathan.cavitt@intel.com>

For platforms that use Aux CCS, wait for aux invalidation to
complete by checking the aux invalidation register bit is
cleared.

[Intel-gfx] [PATCH v3 5/5] drm/i915/gt: Support aux invalidation on all engines

[Andi Shyti]

Perform some refactoring with the purpose of keeping in one
single place all the operations around the aux table
invalidation.

With this refactoring add more engines where the invalidation
should be performed.
