Our current GPGPU_WALKER code only supports up to 64 threads.
On HSW we could use up to 70 and TGL up to 112, but only if the walker
is adjusted so the width does not exceed 64. Work to support this is
in progress.
Previous to this change, we might try to downgrade to SIMD8 if the
SIMD16 shader spilled. Since HSW and TGL have the max number of
threads above 64, we would then try to emit an invalid GPGPU walker
command.

Because we set the needs_data_cache bit from the NIR during compilation,
any time a shader was pulled out of the pipeline cache, we wouldn't set
the bit and the data cache was disabled. Fortunately, on Gen8+, this
bit is ignored because we always use the ALL section in the L3$ config
instead of separate DC and RO sections. On Gen7, however, this meant
that we were basically never running with the data cache enabled and our
compute performance was suffering massively because of it. This commit
improves Geekbench 5 scores on my Haswell GT3 by roughly 330% (no,
that's not a typo).

Provide a generic interface which manages aux resolves in ISL. The
feature differences between this and what's in iris is:
* Support for media compression. ISL_AUX_USAGE_MC behaves differently
from many other usages of CCS, so it was useful to implement this
support upfront, while designing the interfaces.
* Optimizations for full-surface writes. For example, after a
full-surface write occurs with ISL_AUX_USAGE_CCS_E in the PARTIAL_CLEAR
state, isl_aux_state_transition_write() returns COMPRESSED_NO_CLEAR
instead of COMPRESSED_CLEAR.
A performance suggestion for main-surface-invalidating/replacing writes

The other source of the multiply will be interpreted as a uint32_t in an
XOR instruction. Any source modifiers with either not be interpreted at
all or will be misinterpreted due to the differing types.
If the other operand of the multiplication has a source modifier, just
emit an extra move to resolve the source modifiers.
The negation source modifier problem is difficult to reproduce due to an
algebraic optimization that changes (-a*b) to -(a*b). However, changes
in MR !1359 push the negations back down.
On Gen7+ it might be possible to do slightly better for an abs() source
modifier by using BFI2 as a glorified copysign().
On Gen8+ it might be possible to do slightly better for a neg() source
modifier by emitting (~a ^ b).
There were no shader-db changes on any Intel platform, so I think we can
deal with that problem when it arises.

At this point this simply involves fixing the initialization of the

Currently the "Source0 Alpha Present to RenderTarget" bit of the RT
write message header is derived from brw_wm_prog_data::replicate_alpha.
However the src0_alpha payload is provided anytime it's specified to
the logical message. This could theoretically lead to an
inconsistency if somebody provided a src0_alpha value while
brw_wm_prog_data::replicate_alpha was false, as I'm planning to do in
a future commit in order to implement a hardware workaround.
Instead calculate the header bit based on whether a src0_alpha value
was provided to the logical message, which guarantees the same
behavior on pre-ICL and ICL+ (the latter used an extended descriptor
bit for this which didn't suffer from the same issue). Remove the
brw_wm_prog_data::replicate_alpha flag.

Together with the fixup_nomask_control_flow() pass introduced in a
previous patch, this implements a less invasive alternative to the
workaround documented in the hardware spec for GEN:BUG:1407528679,
which doesn't involve disabling structured control flow.
Under some conditions Gen12 hardware can end up executing a BB with
all channels disabled, which will lead to the execution of any NoMask
instructions in it, even though any execution-masked instructions will
be correctly shot down. This could break assumptions of the SWSB pass
if the data computed by a NoMask instruction is synchronized against
by using an SWSB annotation baked into a regular execution-masked
instruction, since the first (NoMask) instruction may be executed
redundantly by the hardware, even though the second will correctly be
shot down, potentially leading to a RaW or WaW hazard if a third
instruction subsequently accesses the destination register of the
first instruction.
