[PATCH v6 0/2] Refactor Gen11+ SAGV support

[PATCH v6 0/2] Refactor Gen11+ SAGV support

[Stanislav Lisovskiy]

For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.

Stanislav Lisovskiy (2):
  drm/i915: Refactor intel_can_enable_sagv
  drm/i915: Restrict qgv points which don't have enough bandwidth.

[PATCH v6 1/2] drm/i915: Refactor intel_can_enable_sagv

[Stanislav Lisovskiy]

Currently intel_can_enable_sagv function contains
a mix of workarounds for different platforms
some of them are not valid for gens >= 11 already,
so lets split it into separate functions.

v2:
    - Rework watermark calculation algorithm to
      attempt to calculate Level 0 watermark
      with added sagv block time latency and
      check if it fits in DBuf in order to
      determine if SAGV can be enabled already
      at this stage, just as BSpec 49325 states.
      if that fails rollback to usual Level 0
      latency and disable SAGV.
    - Remove unneeded tabs(James Ausmus)

v3: Rebased the patch

[Intel-gfx] [PATCH v6 1/2] drm/i915: Refactor intel_can_enable_sagv

[Stanislav Lisovskiy]

Currently intel_can_enable_sagv function contains
a mix of workarounds for different platforms
some of them are not valid for gens >= 11 already,
so lets split it into separate functions.

v2:
    - Rework watermark calculation algorithm to
      attempt to calculate Level 0 watermark
      with added sagv block time latency and
      check if it fits in DBuf in order to
      determine if SAGV can be enabled already
      at this stage, just as BSpec 49325 states.
      if that fails rollback to usual Level 0
      latency and disable SAGV.
    - Remove unneeded tabs(James Ausmus)

This loses the interlaced mode check that the skl and icl functions
have, which is still needed for TGL

This function is already only called on gen12+ - could drop the if
check, and the entire else block.

I understand why you are goto'ing to avoid the extra indent below - can
the block between here and compute_ddb just be extracted to a separate
function instead?

This loses the interlaced mode check that the skl and icl functions
have, which is still needed for TGL

This function is already only called on gen12+ - could drop the if
check, and the entire else block.

[PATCH v6 2/2] drm/i915: Restrict qgv points which don't have enough bandwidth.

[Stanislav Lisovskiy]

According to BSpec 53998, we should try to
restrict qgv points, which can't provide
enough bandwidth for desired display configuration.

Currently we are just comparing against all of
those and take minimum(worst case).

v2: Fixed wrong PCode reply mask, removed hardcoded
    values.

v3: Forbid simultaneous legacy SAGV PCode requests and
    restricting qgv points. Put the actual restriction
    to commit function, added serialization(thanks to Ville)
    to prevent commit being applied out of order in case of
    nonblocking and/or nomodeset commits.

v4:
    - Minor code refactoring, fixed few typos(thanks to James Ausmus)
    - Change the naming of qgv point
      masking/unmasking functions(James Ausmus).
    - Simplify the masking/unmasking operation itself,
      as we don't need to mask only single point per request(James Ausmus)
    - Reject and stick to highest bandwidth point if SAGV
      can't be enabled(BSpec)
