vc4: Flush the job early if we're referencing too many BOs.
If we get up toward 256MB (or whatever the CMA area size is),
VC4_GEM_CREATE will start throwing errors. Even if we don't trigger
that, when we flush the kernel's BO allocation for the CLs or bin
memory may end up throwing an error, at which point our job won't get
rendered at all.
Just flush early (half of maximum CMA size) so that hopefully we never
get to that point.

vc4: Don't abort when a shader compile fails.
It's much better to just skip the draw call entirely. Getting this
information out of register allocation will also be useful for
implementing threaded fragment shaders, which will need to retry
non-threaded if RA fails.

vc4: Restructure the simulator mode.
Rather than having simulator mode changes scattered around vc4_bufmgr.c
and vc4_screen.c, make vc4_bufmgr.c just call a vc4_simulator_ioctl, which
then dispatches to a corresponding implementation.
This will give the simulator support a centralized place to do tricks like
storing most BOs directly in simulator memory rather than copying in and
out.
This leaves special casing of mmaping BOs and execution, because of the
winsys mapping.

vc4: Fix incorrect clearing of Z/stencil when cleared separately.
The clear of Z or stencil will end up clearing the other as well, instead
of masking. There's no way around this that I know of, so if we are
clearing just one then we need to draw a quad.
Fixes a regression in the job-shuffling code, where the clear values move
to the job and don't just have the last clear's value laying around when
you do glClear(DEPTH) and then glClear(STENCIL) separately
(ext_framebuffer_multisample-clear 4 depth)).
This causes regressions in ext_framebuffer_multisample/multisample-blit
depth and ext_framebuffer_multisample/no-color depth, but these were
formerly false positives due to the reference image also being black. Now
the reference and test images are both being drawn, and it looks like
there's an incorrect resolve of depth during blitting to an MSAA FBO.

vc4: Speed up glGenerateMipmaps by avoiding shadow baselevel.
To support general GL_TEXTURE_BASE_LEVEL we have to copy to a temporary
miptree. However, if a single level is being selected, we can use the
existing miptree and force all the sampling to be from that particular
level.
This avoids a ton of software fallbacks in glGenerateMipmaps(), which uses
base levels in the blit implementation in gallium. Improves "glmark2 -b
terrain" from 2 fps to 3 (perhaps some more precision would be useful?),
and cuts its CPU usage during the benchmarking from ~30% to ~10% (total
CPU time from 8.8s to 7.6s).

vc4: Just stream out fallback IB contents.
The idea I had when I wrote the original shadow code was that you'd see a
set_index_buffer to the IB, then a bunch of draws out of it. What's
actually happening in openarena is that set_index_buffer occurs at every
draw, so we end up making a new shadow BO every time, and converting more
of the BO than is actually used in the draw.
While I could maybe come up with a better caching scheme, for now just
do the simple thing that doesn't result in a new shadow IB allocation
per draw.

vc4: Match VS outputs to FS inputs.
If the VS doesn't output a value that the FS needs, we still need to read
the right contents for the remaining FS inputs, by emitting padding. And
if the VS outputs something the FS doesn't need, we shouldn't put it in
the VPM at all (so the code producing it can get DCEed).
Fixes 77 piglit tests.

vc4: Split the coordinate shader to its own vc4_compiled_shader.
Merging VS and CS into the same struct wasn't winning us anything except
for not allocating a separate BO (but if we want to pack programs into
BOs, we should pack not just those 2 programs together). What it was
getting us was a bunch of code duplication about hash table lookups and
propagating vc4_compile contents into a vc4_compiled_shader.
I was about to make the situation worse with indirect uniform buffer
access.

vc4: Add support for two-sided color.
It's fairly easy, thanks to Rob Clark's lowering code. Fixes
two-sided-lighting and 4 vertex-program-two-side testcases, while
regressing 8 testcases that involve enabling two-sided color while only
initializing one of the two colors in the VS. If you're enabling two
sided color, it's of course expected that you really do set up both
colors, so this is still an improvement (and when we set up a linker for
TGSI, we'll hopefully fix those 8 fails).

This required building a shader parser that would walk the program to find
where the texturing-related uniforms are in the uniforms stream.
Note that as of this commit, a new kernel is required for rendering on
actual VC4 hardware (currently that commit is named "drm/vc4: Introduce
shader validation and better command stream validation.", but is likely to
be squashed as part of an eventual merge of the kernel driver).

faster.

vc4: Switch to actually generating vertex and fragment shader code from TGSI.
This introduces an IR (QIR, for QPU IR) to do optimization on. It's a
scalar, SSA IR in general. It looks like optimization is pretty easy this
way, though I haven't figured out if it's going to be good for our weird
register allocation or not (or if I want to reduce to basically QPU
instructions first), and I've got some problems with it having some
multi-QPU-instruction opcodes (SEQ and CMP, for example) which I probably
want to break down.
Of course, this commit mostly doesn't work, since many other things are
still hardwired, like the VBO data.
v2: Rewrite to use a bunch of helpers (qir_OPCODE) for emitting QIR
instructions into temporary values, and make qir_inst4 take the 4 args
separately instead of an array (all later callers wanted individual
args).

copyright for those. I also based my initial hardcoded shaders and
