a35269cf44 iris: Implement ARB_indirect_parameters
iris_draw_vbo is divided into two functions to remove unnecessary
operations from the loop. This implementation of ARB_indirect_parameters
takes into account NV_conditional_render by saving MI_PREDICATE_RESULT
at the start of a draw call and restoring it at the end also the result
of NV_conditional_render is taken into account when computing predicates
that limit draw calls for ARB_indirect_parameters in a similar way
to 1952fd8d in ANV.

v2: Optimize indirect draws (suggested by Kenneth Graunke)
v3: (by Kenneth Graunke)
 - Fix an issue where indirect draws wouldn't set patch information
   before updating the compiled TCS.
 - Move some code back to iris_draw_vbo to avoid duplicating it.
 - Fix minor indentation issues.

21a0be4a79 iris: Split iris_update_draw_info into two functions.
Shader draw parameters need updating on each iteration of a multidraw
loop, but the primitive based information only needs to be updated once.

Also, patch information needs to be recorded before filling out the TCS
program key, as it determines the number of HS instances.

c5c12bdd00 iris: Try to recover from GPU hangs.
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.

c3701e9070 iris: Mark render batches as non-recoverable.
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.

8b81256469 iris: Reorganise execbuf to have a single point of failure
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.

748f603390 gallivm: fix broken 8-wide s3tc decoding
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.

b15c46e6bf freedreno/ir3: move const_state to ir3_shader
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.

d41cdef2a5 nir: Use the flrp lowering pass instead of nir_opt_algebraic
I tried to be very careful while updating all the various drivers, but I
don't have any of that hardware for testing. :(

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
during code generation as a(1-c)+bc.  On all other platforms 64-bit
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.

v2: Add panfrost changes.

Iron Lake and GM45 had similar results. (Iron Lake shown)

4e110eca42 nir: nir_shader_compiler_options: drop native_integers
Driver which do not support native integers should use a lowering
pass to go from integers to floats.

050b934a24 panfrost: Refactor blend descriptors
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.

If PIPE_CAP_PACKED_UNIFORMS is not set uniforms are vec4 aligned,
so lima_nir_lower_uniform_to_scalar should use first channel of vec4
for float uniforms.
