Or current render target cache setting is to key on the binding table
index, meaning the HW associates a number in the range [0, 7] to a
RENDER_SURFACE_STATE description. If you want change the render target
0 between 2 draw calls, you need to insert a PIPE_CONTROL in between
the 2 draw calls with pb-stall + rt-flush in order to flush an writes
to a previous RENDER_SURFACE_STATE that has now becomed disassociated
with the [0, 7] number.
This PIPE_CONTROL taking care of the flush is dealt with in
cmd_buffer_maybe_flush_rt_writes(). This function diffs the current
BTI setup for render targets (first 0 to 7 BTIs) with what the next
fragment shader wants.
The issue here is we might have a render pass with 0 color attachments
and yet in 98cdb9349a we added one pointing to the render target 0,
but in the emit_binding_table() when we finally program the BTI, we
check the render pass color count and program a null surface state
instead of an actual surface state. And this leads to hangs because
the render target cache will end up with inconsistent state data.

Intel GPUs have a saturate destination modifier, and
brw_fs_opt_saturate_propagation tries to replace explicit saturate
operations with this destination modifier. That pass is limited in
several ways. If the source of the explicit saturate is in a different
block or if the source of the explicit saturate is live after the
explicit saturate, brw_fs_opt_saturate_propagation will be unable to
make progress.
This optimization exists to help brw_fs_opt_saturate_propagation make
more progress. It tries to move NIR fsat instructions to the same block
that contains the definition of its source. It does this only in cases
where it will not create additional live values. It also attempts to do
this only in cases where the explicit saturate will ultimiately be
converted to a destination modifier.
v2: Fix metadata_preserve when theres no progress and use
nir_metadata_control_flow when there is progress. All suggested by
Alyssa.
v3: Fix a typo in the file header comment. Noticed by Ken. Don't
require nir_metadata_instr_index. Use nir_def_rewrite_uses_after instead
of open-coding something slightly more specific. Both suggested by Ken.
