[Intel-gfx] [PATCH V4 0/6] drm/i915/gt: Initialize unused MOCS entries to L3_WB

[Ayaz A Siddiqui]

Gen >= 12 onwards MOCS table doesn't have a setting for PTE
so I915_MOCS_PTE is not a valid index and it will have different
MOCS values are based on the platform.

To detect these kinds of misprogramming, all the unspecified and
reserved MOCS indexes are set to WB_L3. TGL/RKL unspecified MOCS
indexes are pointing to L3 UC are kept intact to avoid API break.

This series also contains patches to program BLIT_CCTL and
CMD_CCTL registers to UC.
Since we are quite late to update MOCS table for TGL so added
a new MOCS table for ADL family.

V2:
  1. Added CMD_CCTL to GUC regset list so that it can be restored
     after engine reset.
  2. Checkpatch warning removal.

V3:
 1. Changed implementation to have a framework only.
 2. Added register type for proper application.
 3. moved CMD_CCTL programming to a separate patch.
 4. Added L3CC initialization during gt reset so that MOCS indexes are
    set before GuC initialization.
 5. Removed Renderer check for L3CC verification in selftest.

V4:
 1. Moved register programming in Workaorund section as fake workaround.
 2. Removed seperate ADL mocs table, new logic is to set unused index as
 L3_WB for gen12 platform except TGL/RKL.

[Intel-gfx] [PATCH V4 1/6] drm/i915/gt: Add support of mocs propagation

[Ayaz A Siddiqui]

Now there are lots of Command and registers that require mocs index
programming.
So propagating mocs_index from mocs to gt so that it can be
used directly without having platform-specific checks.

[Intel-gfx] [PATCH V4 2/6] drm/i915/gt: Set CMD_CCTL to UC for Gen12 Onward

[Ayaz A Siddiqui]

Cache-control registers for Command Stream(CMD_CCTL) are used
to set catchability for memory writes and reads outputted by
Command Streamers on Gen12 onward platforms.

These registers need to point un-cached(UC) MOCS index.

[Intel-gfx] [PATCH V4 3/6] drm/i915/gt: Set BLIT_CCTL reg to un-cached

[Ayaz A Siddiqui]

Blitter commands which do not have MOCS fields rely on
cacheability of BlitterCacheControlRegister which was mapped
to index 0 by default.Once we changed the MOCS value of
index 0 to L3 WB, tests like gem_linear_blits started failing
due to a change in cacheability from UC to WB.

Program and place the BlitterCacheControlRegister in
build_aux_regs().

[Intel-gfx] [PATCH V4 4/6] drm/i915/gt: Initialize unused MOCS entries with device specific values

[Ayaz A Siddiqui]

Historically we've initialized all undefined/reserved entries in
a platform's MOCS table to the contents of table entry #1 (i.e.,
I915_MOCS_PTE).
Going forward, we can't assume that table entry #1 will always
contain suitable values to use for undefined/reserved table
indices. We'll allow a platform-specific table index to be
selected at table initialization time in these cases.

This new mechanism to select L3 WB entry will be applicable for
all the Gen12+ platforms except TGL and RKL.

Since TGL and RLK are already in production so their mocs settings
are intact to avoid ABI break.

[Intel-gfx] [PATCH V4 5/6] drm/i915/gt: Initialize L3CC table in mocs init

[Ayaz A Siddiqui]

From: Sreedhar Telukuntla <sreedhar.telukuntla@intel.com>

Initialize the L3CC table as part of mocs initialization to program
LNCFCMOCSx registers so that the mocs settings are available for
selection for subsequent memory transactions in the driver load path.

Apart from the above requirement, this patch is also needed for platforms
which does not have any renderer engine.
We have verified that value programmed LNCFCMOCSx is retained for
XEHP-SDV, while we lose those values for DG1/TGL.

[Intel-gfx] [PATCH V4 6/6] drm/i915/selftest: Remove Renderer class check for l3cc table read

[Ayaz A Siddiqui]

Some platform like XEHPSVD does not have Renderer engines. since
read_l3cc_table() is guarded by renderer class due to that check
of L3CC table was not being performed on those platforms.

I think I mentioned it on the v3 review too, but you can drop the
'i915_mocs_index_gt' name here since we don't reference it anywhere else
in the code that I can see.  Just using an anonymous structure would be
fine.

Aside from that,

The comment's indentation here looks a bit strange.  It should either be
indented the same amount as the line below it, or it should be moved
above the 'if.'

I think we do have a few other fake workarounds that we can move over to
here eventually (e.g., FtrPerCtxtPreemptionGranularityControl), but we
can track those down and move them over in followup patches.

Aside from the two minor comment tweaks,

As on the previous patch, the indentation of the comment here is unusual.

Unlike CMD_CCTL, BLIT_CCTL is _not_ a masked register so we don't want
to use wa_masked_field_set.  Instead this should be a wa_write_clr_set.

In the future we can move over WaDisable3DMidCmdPreemption,
WaDisableGPGPUMidCmdPreemption, and probably several others, but we can
do that in a separate series down the road.


After applying the s/wa_masked_field_set/wa_write_clr_set/ fix above,
the rest of the patch looks correct so

I think you meant '&&' here rather than '||' (otherwise this statement
will always evaluate to true).

Just FYI, I believe the difference here isn't the platform itself, but
rather GuC vs execlists.  With GuC submission (currently enabled by
default on XeHP and beyond), the LNCFMOCS registers are added to the
GuC's save/restore list (in guc_mmio_regset_init()) so that they're
always saved/restored across resets without any special action by i915.
But when we're using execlists, as is the default on TGL and (for now)
DG1, the driver needs to explicitly re-write the registers after a
reset, which is what the call inside intel_mocs_init_engine() takes care
of.

You might want to clarify that slightly in the commit message, but
otherwise

Re: [Intel-gfx] [PATCH V4 6/6] drm/i915/selftest: Remove Renderer class check for l3cc table read

Yeah, Xe_HP SDV doesn't have an RCS engine, but it does have compute
engines (CCS) that fill the same role.  I have the initial patches to
enable the compute engine ready to send upstream; just waiting on one of
the userspace drivers (either Mesa or OCL) to have their own merge
requests ready so that I can reference that as our userspace consumer.

Maybe we should hold off on this patch for now and change this to

        if (!err && engine->flags & I915_ENGINE_HAS_RCS_REG_STATE)

which will apply to both the render and compute engines at that point?
Or, since these registers are global and not engine-specific, we could
adjust the code to just do this once, with whatever the GT's first
engine happens to be (doesn't matter if it's RCS, CCS, BCS, VCS, or
VECS) so that we're not repeating the same process multiple times
needlessly?

this is including TGL. Shouldn't TGL be the exception here?

Until now we haven't been programming CMD_CCTL, so it's basically been
pointing at entry 0.  On TGL/RKL, undefined entry 0 is treated as UC.
Now that we start setting CMD_CCTL here, it will switch to point at
entry 3, which is explicitly UC, so the behavior shouldn't change, but
the code should be more obvious.

The place where TGL/RKL need an exception is how to setup undefined
table entries (which may be used by userspace; we're not going to point
CMD_CCTL or BLIT_CCTL at any of those now).  In general those undefined
entries should be treated as L3, but for ABI reasons we need to keep
them as UC on TGL/RKL.
