[Intel-gfx] [PATCH v2 1/4] drm/i915: Use separate "DC off" power well for ADL-P and DG2

[Radhakrishna Sripada]

From: Matt Roper <matthew.d.roper@intel.com>

Although ADL-P and DG2 both use the same general power well setup, the
DC5/DC6 requirements are slightly different which means each platform
should have its own "DC off" power well.

DG2 (i.e., Xe_HPD IP) requires that DC5 be disabled whenever PG2 is
active.  However ADL-P (i.e., Xe_LPD IP) only requires DC5/DC6 to be
disabled when the PGC or PGD subwells are active; we should be able to
remain in these DC states when PGB and general PG2 functionality is in
use.

v2: Use dc_of as power well name.
    Move xehpd power domain definitions near power well definition.(Imre)

[Intel-gfx] [PATCH v2 2/4] drm/i915/mtl: Re-use ADL-P's "DC off" power well

[Radhakrishna Sripada]

From: Matt Roper <matthew.d.roper@intel.com>

As with ADL-P, MTL's "DC off" power well should be a dependency of the
PGC and PGD power wells, not the entire PG2 well.  In fact, the DC5/DC6
requirements between the two platforms are the same, so the Xe_LPD "DC
off" well definition can just be re-used for Xe_LPD+.

[Intel-gfx] [PATCH v2 3/4] drm/i915/mtl: Extend Wa_22011802037 to MTL A-step

[Radhakrishna Sripada]

From: Madhumitha Tolakanahalli Pradeep <madhumitha.tolakanahalli.pradeep@intel.com>

Wa_22011802037 was being applied to all graphics_ver 11 & 12. This patch
updates the if statement to apply the W/A to right platforms and extends
it to MTL-M:A step.

v1.1: Fix checkpatch warning.
v2: Change the check to reflect the wa at other palces(Lucas)

It doesn't look like this patch is complete?  It's only changing one
condition for Wa_22011802037, even though there are several in the code.
From a quick grep, you're still missing updates for at least
guc_ctl_wa_flags, execlists_reset_prepare, and __intel_engine_stop_cs.

Since this workaround is a complicated one that touches so many areas of
the code, and has a complex platform list, it's probably time to factor
the condition out into a needs_wa_22011802037() helper or something.

Actually, scratch that.  Those other spots already have a MTL clause as
part of the condition.  But in that case it means the commit message
here is inaccurate; you're not extending this workaround to MTL a-step
because that already happened on a previous patch.  You're just
providing a fix for an incomplete implementation that happened earlier.
The commit message should be explaining that.

I still suggest doing this, especially since we've clearly screwed up
the handling of this workaround at least once already.

Apparently this patchset broke bat-dg2-11 machine on CI.
Both pre and post merge results suggests it [1][2].
Regarding bat-dg2-11, this machine contains DG2 AND ADL cards.
So the bug hits ADL card on bat-dg2-11 machine. No idea why only this 
one, there are multiple bat machines with ADL.
