[Intel-gfx] [PATCH 1/3] drm/i915/gt: Move wal_get_fw_for_rmw()

[Lucas De Marchi]

Move helper function to get all the forcewakes required by the wa list
to the top, so it can be re-used by other functions.

[Intel-gfx] [PATCH 2/3] drm/i915/gt: Fix context workarounds with non-masked regs

[Lucas De Marchi]

Most of the context workarounds tweak masked registers, but not all. For
masked registers, when writing the value it's sufficient to just write
the wa->set_bits since that will take care of both the clr and set bits
as well as not overwriting other bits.

However there are some workarounds, the registers are non-masked. Up
until now the driver was simply emitting a MI_LOAD_REGISTER_IMM with the
set_bits to program the register via the GPU in the WA bb. This has the
side effect of overwriting the content of the register outside of bits
that should be set and also doesn't handle the bits that should be
cleared.

Kenneth reported that on DG2, mesa was seeing a weird behavior due to
the kernel programming of L3SQCREG5 in dg2_ctx_gt_tuning_init(). With
the GPU idle, that register could be read via intel_reg as 0x00e001ff,
but during a 3D workload it would change to 0x0000007f. So the
programming of that tuning was affecting more than the bits in
L3_PWM_TIMER_INIT_VAL_MASK. Matt Roper noticed the lack of rmw for the
context workarounds due to the use of MI_LOAD_REGISTER_IMM.

So, for registers that are not masked, read its value via mmio, modify
and then set it in the buffer to be written by the GPU. This should take
care in a simple way of programming just the bits required by the
tuning/workaround. If in future there are registers that involved that
can't be read by the CPU, a more complex approach may be required like
a) issuing additional instructions to read and modify; or b) scan the
golden context and patch it in place before saving it; or something
else. But for now this should suffice.

Scanning the context workarounds for all platforms, these are the
impacted ones with the respective registers

	mtl: DRAW_WATERMARK
	mtl/dg2: XEHP_L3SQCREG5, XEHP_FF_MODE2
	gen12: GEN12_FF_MODE2

ICL has some non-masked registers in the context workarounds:
GEN8_L3CNTLREG, IVB_FBC_RT_BASE and VB_FBC_RT_BASE_UPPER, but there
shouldn't be an impact. The first is already being manually read and the
other 2 are intentionally overwriting the entire register.

Speaking of GEN12_FF_MODE2...there's a big scary comment above that
workaround write which says that register "will return the wrong value
when read."  I think with this patch, we'll start doing a RMW cycle for
the register, which could mix in some of this "wrong value".  The
comment mentions that the intention is to write the whole register,
as the default value is 0 for all fields.

Maybe what we want to do is change gen12_ctx_gt_tuning_init to do

    wa_write(wal, GEN12_FF_MODE2, FF_MODE2_TDS_TIMER_128);

so it has a clear mask of ~0 instead of FF_MODE2_TDS_TIMER_MASK, and
then in this patch update your condition below from

+		if (wa->masked_reg || wa->set == U32_MAX) {

to

+		if (wa->masked_reg || wa->set == U32_MAX || wa->clear == U32_MAX) {

because if we're clearing all bits then we don't care about doing a
read-modify-write either.

Good point. That also means we don't need to backport this patch to
stable kernel to any gen12, since overwritting the other bits is
actually the intended behavior.

In order to ignore read back when verifying, we would still need to use
wa_add(), but changing the mask. We don't have a wa_write() that ends up
with { .clr = ~0, .read_mask = 0 }.

	wa_add(wal,
	       GEN12_FF_MODE2,
	       ~0, FF_MODE2_TDS_TIMER_128,
	       0, false);

yeah... and maybe also warn if wa->read is 0, which means it's one
of the registers we can't/shouldn't read from the CPU.

Good point!  Though, I just noticed another bug here:

gen12_ctx_workarounds_init sets FF_MODE2_GS_TIMER_224 to avoid hangs
in the HS/DS unit, after gen12_ctx_gt_tuning_init set TDS_TIMER_128
for performance.  One of those is going to clobber the other; we're
likely losing the TDS tuning today.  Combining those workarounds into
one place seems like an easy way to fix that.

we are not losing it today. As long as the wa list is the same, we do detect collisions when
adding workarounds and they are coallesced before applying. However,
indeed if we change this to make clear be ~0, then they will collide and
we will see a warning.

Applying them together in a single operation would indeed solve it
with a side-effect of moving this back to the workarounds. Either that
or

a) we handle the read_back == 0 && clear == U32_MAX specially when
    adding WAs. If that is true, then the check for collisions can
    be adjusted to allow that.

b) we give up on this approach and proceed with one of

	1) scan the ctx wa list. If it has any non-masked register,
	   we submit a job to read it from the GPU side. MCR will
	   make this harder as the steering from the GPU side is
	   different than the CPU

	2) emit additional commands to read and modify the register from
	   the GPU side

	3) find the register in the golden context and patch it in place




>one place seems like an easy way to fix that.

I'm leaning towards this option in the hope we don't have have
another GEN12_FF_MODE2 in future.

Matt, we've been pushing towards separating the tuning from the WAs, but
here we'd go the other way. Anything against doing this for now?

[Intel-gfx] [PATCH 3/3] drm/i915/gt: Drop read from GEN8_L3CNTLREG in ICL workaround

[Lucas De Marchi]

Now that non-masked registers are already read before programming the
context reads, the additional read became redudant, so remove it.
