This provides a way for the application to query whether any resets have
happened, which lets us expose "robust" contexts. This also enables the
KHR_robust_buffer_access_behavior tests.
This mechanism lets the driver inform the state tracker about GPU
resets, say for destroying a robust API context and reporting a "device
lost" error to the application, making it take action to deal with this.
The iris batch module now tries to detect that the kernel has banned
our GEM context, creates a new non-banned context, and informs the
iris context module that all assumptions about state are now invalid
and it needs to reinitialize the relevant state.
Based on Chris Wilson's work, but significantly rewritten by me.
Adapted from Chris Wilson's patch. The comment is largely his.
Currently, when iris hangs the GPU, it will continue sending batches
which incrementally update the state, assuming it's preserved across
batches. However, the kernel's GPU reset support reinitializes the
guilty context to the default GPU state (reasonably not wanting to
trust the current state). This ends up resetting critical things
like STATE_BASE_ADDRESS, causing memory accesses in all subsequent
batches to be garbage, and almost certainly result in more hangs
until we're banned or we kill the machine.
We now ask the kernel to ban our render context immediately, so we
notice we've gone off the rails as fast as possible. Eventually, we'll
attempt to recover and continue. For now, we just avoid torching the
GPU over and over.
I don't know why I thought NIR_PASS always set the progress variable.
Derp.

Propagate the failure from GEM_EXECBUFFER2, cleanup then report failure
if need be. We retain the current behaviour to abort() at the first sign
of trouble -- for a non-robustness context, arguably this is the right
thing to do as the client cannot recover, and the system state is lost.
How to properly integrate with KHR_robustness and reset-strategy is
left as a future exercise.

Brian noticed there was an uninitialized var for the 8-wide case and 128
bit blocks, which made it always crash. Likewise, the 64bit block case
had another crash bug due to type mismatch.
Color decode (used for all s3tc formats) also had a bogus shuffle for
this case, leading to decode artifacts.
Fix these all up, which makes the code actually work 8-wide. Note that
it's still not used - I've verified it works, and the generated assembly
does look quite a bit simpler actually (20-30% less instructions for the
s3tc decode part with avx2), however in practice it still seems to be
sligthly slower for some unknown reason (tested with openarena) on my
haswell box, so for now continue to split things into 4-wide vectors
before decoding.

For a6xx, we construct/emit a single VS const state used for both
binning pass and draw pass. So far we were mostly getting lucky that
there were not (obvious) mismatches between the const_state (like
different lowered immediates) between the binning and draw pass
VS ir3_shader_variant.
And I guess this situation will come up more as GS and tess is added
into the equation.
Since really everything about the const state is not specific to the
variant, move this. The main exception is lowered immediates, but these
are the last to appear in the layout, and it doesn't hurt for each new
shader variant to just append any immed's it lowers to the end of the
immediate state.

i965 is the only platform that sets always_precise = true, and it is
only set true for fragment shaders. Gen4 and Gen5 both set lower_flrp32
only for vertex shaders. For fragment shaders, nir_op_flrp is lowered

nir_op_flrp and on Gen11 32-bit nir_op_flrp are lowered using the old
nir_opt_algebraic method.
No changes on any other Intel platforms.

This commit does a fairly large cleanup of blend descriptors, although
there should not be any functional changes. In particular, we split
apart the Midgard and Bifrost blend descriptors, since they are
radically different. From there, we can identify that the Midgard
descriptor as previously written was really two render targets'
descriptors stuck together. From this observation, we split the Midgard
descriptor into what a single RT actually needs. This enables us to
correctly dump blending configuration for MRT samples on Midgard. It
also allows the Midgard and Bifrost blend code to peacefully coexist,
with runtime selection rather than a #ifdef. So, as a bonus, this will
help the future Bifrost effort, eliminating one major source of
compile-time architectural divergence.

We currently set this state in the draw-module twice on each draw, but

But it turns out, we're going to have to do more; namely flush when the
state changes. This will incur a large performance penalty due to the
excessive setting.
Instead, let's rely on the CSO caching making sure that
llvmpipe_set_so_targets doesn't get called needlessly, and setup the

Inline writes skip transfer map/unamp at the cost of an extra copy
on the data during execbuffer. That is generally a win for small
transfers. But the heuristic to use inline writes based on buffer
sizes rather than transfer sizes makes little sense. More
importantly, inline writes miss optimizations that are done for
buffer transfers.
Let's just use transfers.

This handles the usual case. 8-bit register access parallels 16-bit
access, but with one major caveat: in 8-bit mode, only half of the
register file is actually (directly) accessible as sources. In
particular, for each 16-bit integer register (hrN), we can only index a
*single* 8-bit integer (qrN), corresponding to the lower 8-bits. To get
the upper 8-bits, it is required to do an explicit shift. For example,
to add the bytes of a 16-bit integer hr0.x and get the result as an
8-bit qr0, you'd need to do something like:
ilsr hr1.x, hr0.x, #8
iadd qr0.x, qr0.x, qr1.x
This scheme diverges from 32-bit registers, in that both the upper and
lower halves of a 32-bit register are individually accessible as a pair
of half registers. For contrast, to add the lower and upper 16-bits of a
32-bit integer r0.x, you can just:
iadd hr0.x, hr0.x, hr1.x
Since hr1.x = upper 16-bit of r0.x.
