[Intel-gfx] [PATCH 1/4] drm/i915/pvc: Annotate two more workaround/tuning registers as MCR

[Matt Roper]

XEHPC_LNCFMISCCFGREG0 and XEHPC_L3SCRUB are both in MCR register ranges
on PVC (with HALFBSLICE and L3BANK replication respectively), so they
should be explicitly declared as MCR registers and use MCR-aware
workaround handlers.

The workarounds/tuning settings should still be applied properly on PVC
even without the MCR annotation, but readback verification on
CONFIG_DRM_I915_DEBUG_GEM builds could potentitally give false positive
"workaround lost on load" warnings on parts fused such that a unicast
read targets a terminated register instance.

[Intel-gfx] [PATCH 2/4] drm/i915/gen11: Wa_1408615072/Wa_1407596294 should be on GT list

[Matt Roper]

The UNSLICE_UNIT_LEVEL_CLKGATE register programmed by this workaround
has 'BUS' style reset, indicating that it does not lose its value on
engine resets.  Furthermore, this register is part of the GT forcewake
domain rather than the RENDER domain, so it should not be impacted by
RCS engine resets.  As such, we should implement this on the GT
workaround list rather than an engine list.

[Intel-gfx] [PATCH 3/4] drm/i915/xehp: LNCF/LBCF workarounds should be on the GT list

[Matt Roper]

Although registers in the L3 bank/node configuration ranges are marked
as having "DEV" reset characteristics in the bspec, this appears to be a
hold-over from pre-Xe_HP platforms.  In reality, these registers
maintain their values across engine resets, meaning that workarounds
and tuning settings targetting them should be placed on the GT
workaround list rather than an engine workaround list.

Note that an extra clue here is that these registers moved from the
RENDER forcewake domain to the GT forcewake domain in Xe_HP; generally
RCS/CCS engine resets should not lead to the reset of a register that
lives outside the RENDER domain.

Re-applying these registers on engine resets wouldn't actually hurt
anything, but is unnecessary and just makes it more confusing to anyone
trying to decipher how these registers really work.

[Intel-gfx] [PATCH 4/4] drm/i915/selftest: Use forcewake to sanity check engine wa lists

[Matt Roper]

Although register information in the bspec includes a field that is
supposed to reflect a register's reset characteristics (i.e., whether a
register maintains its value through engine resets), it's been
discovered that this information is incorrect for some register ranges
(i.e., registers that are not affected by engine resets are tagged in a
way that indicates they would be).

We can sanity check workaround registers placed on the RCS/CCS engine
workaround lists (including those placed there via the
general_render_compute_wa_init() function) by comparing against the
forcewake table.  As far as we know, there's never a case where a
register that lives outside the RENDER powerwell will be reset by an
RCS/CCS engine reset.

Looked and it seems DG2 also has GT forcewake domain for XEHP_L3NODEARBCFG.
Shouldn't Wa_14010648519 be fixed as well then? Or am I missing
something?

I think "workaround registers" is too general and makes the sentence a bit
confusing. I believe you mean those registers mentioned in the previous
sentence, right? Maybe s/workaround registers/said registers/?

I think it is safer to use the correct member (wa->reg vs wa->mcr_reg) according
to the value of wa->is_mcr. Coincidently the reg member for both types have the
same offset in the struct, but I do not think we should rely on that.

One issue is that, unlike i915_mmio_reg_offset(),
intel_uncore_forcewake_for_reg() is not implemented with generics and expects
i915_reg_t. A workaround here would be "converting" the wa->mcr_reg (when
wa->is_mcr holds) an i915_reg_t by copying the correct fields. While this is
trivial since both types have only one field, I think the proper way
(future-proof) of doing that is by having a dedicated function/macro to do the
transformation.

Thinking about an alternative approach, do you think we could say that
i915_mcr_reg_t will always have the same fields as i915_reg_t? In that case, we
could tweak the type definition (or at least formalize via code documentation)
to reflect that and then it would be okay to always use wa->reg here, as
i915_mcr_reg_t would be thought as a subclass of i915_reg_t.

Ah, we already have that: mcr_reg_cast()

:-)

So my suggestion is:

    i915_reg_t reg = wa->is_mcr ? mcr_reg_cast(wa->mcr_reg) : wa->reg;

Ans use reg as argument for both intel_uncore_forcewake_for_reg() and
i915_mmio_reg_offset().
