This INTEL_DEBUG option disables lossless compression (also known
as render buffer compression).
v2: (Matt) Use likely(!lossless_compression_disabled) instead of
!likely(lossless_compression_disabled)
(Grazvydas) Update docs/envvars.html

The do32 INTEL_DEBUG option causes the back-end to try to generate a
SIMD32 program when compiling a compute shader regardless of the
specified compute shader workgroup size, which will be useful for
testing SIMD32 code generation in the most common case in which the
workgroup size doesn't exceed the SIMD16 limit so SIMD32 codegen
wouldn't be automatically enabled.

Kind of a handy function. And I'll want it available outside of i965
for common nir-pass helpers.

Even though both tessellation shader stages must be used together, I
still think it makes sense to add separate debug flags for each stage.
It makes it possible to read the TCS/HS, rule out problems, then read
the TES/DS separately, without sifting through as much printed text.
I decided to add both the GL names (tcs/tes) and hardware names (hs/ds)
so they can be used interchangeably.

We need the debug flag parsing and INTEL_DEBUG in the compiler, but we
don't want the dependency on bufmgr (libdrm_intel) in there. Move to
intel_screen.c.
There are now only two lines left in brw_process_intel_debug_variable(),
but we keep it in intel_debug.h to avoid having to expose
'debug_control' as a global variable.

We want to use intel_debug.c in code that doesn't link to dri common.
v2: Remove unnecessary stddef.h include (Topi), use util/debug.h
in all DRI driver and remove driParseDebugString() (Iago).

driParseDebugString() doesn't have actual code to parse comma separated
lists (or any other supported options?); instead it dumbly uses strstr().
This means that INTEL_DEBUG="vec4vs" will trigger both DEBUG_VEC4VS and
DEBUG_VS, as "vs" is also a substring.
We should probably improve the driconf parsing, but for now, just rename
the option so it's usable in the meantime.

At the moment it's not wired up to anything. Later patches will hook
it up to the compute shader back-end.

When compiling, we have a gl_shader_stage (MESA_SHADER_*) enum, and want
to know whether debugging is enabled for that stage. This allows us to
easily translate it into the corresponding debug flag.

With everything in place, we can now use the scalar backend compiler for
vertex shaders on BDW+. We make scalar vertex shaders the default on
BDW+ but add a new vec4vs debug option to force the vec4 backend.
No piglit regressions.
Performance impact is minimal, I see a ~1.5 improvement on the T-Rex
GLBenchmark case, but in general it's in the noise. Some of our
internal synthetic, vs bounded benchmarks show great improvement, 20%-40%
in some cases, but real-world cases are mostly unaffected.

This cleans up the debug flags to be consistently indented, use bit
shifting instead of hex-values and fixes a bug where the new DEBUG_NO8 flag
used the same value as the DEBUG_VUE flag. This was hidden by the numbers not
being aligned. Also removes gaps in the range where DEBUG_IOCTL (0x4) and
DEBUG_REGION (0x400) used to be.

For now, this can only be triggered with a new 'no8' INTEL_DEBUG option
and a new context flag. We'll use the context flag later, but introducing
it now lets us bisect to this commit if it breaks something.

Running shader-db with INTEL_DEBUG=noann reduces the runtime
from ~90 to ~80 seconds on my machine. It also reduces the disk space
consumed by the .out files from 660 MB (676 on disk) to 343 MB (358 on
disk).

This is similar to what we do for 16-wide vs 8-wide fragment shaders.
First we try compiling the geometry shader in DUAL_OBJECT mode. If we
can't do that without spilling, we fall back on DUAL_INSTANCED mode,
which should require less spilling (since it uses an interleaved
layout of payload registers).
In an ideal world we'd fall back to SINGLE mode, which would allow us
to interleave general-purpose registers too (resulting in even less
likelihood of spilling). But at the moment, the vec4 generator and
visitor classes don't have the infrastructure to interleave general
purpose registers, so DUAL_INSTANCED is the best we can do.
As a side benefit this paves the way for implementing instanced
geometry shaders (which are incompatible with DUAL_OBJECT mode).
Since most geometry shaders used in piglit testing are small,
DUAL_INSTANCED mode won't get exercised very much in a normal piglit
run. To force DUAL_INSTANCED mode to be used for all geometry
shaders, set INTEL_DEBUG=nodualobj.

Now that there isn't an intel_context structure, the split between
brw_context.[ch] and intel_context.[ch] is rather awkward and arbitrary.
Removing intel_context.[ch] seems desirable, but not everything really
belongs in brw_context.[ch], either.
Moving INTEL_DEBUG handling into separate intel_debug.[ch] files should
make them relatively easy to find.
