radeonsi also does the same thing. I suspect that this is likely to be a
no-op in reality, but it brings nouveau code closer to what the blob
produces. Plus it makes sense to not try to do auto-derivatives on this.

This allows the driver to signal that it can't handle random
interleaving of attributes across buffers. This is required for
ARB_transform_feedback3, and it's initialized to whatever the previous
value of PIPE_CAP_STREAM_OUTPUT_PAUSE_RESUME was except for nv50 where
it is disabled. Note that the proprietary drivers never expose
ARB_transform_feedback3 on any GT21x's (where nouveau previously did),
and after some effort I was unable to get it to work.

Getting stores to NIR regs to not generate new MOVs is tricky, since the
result we're trying to store into the NIR reg may have been from a
conditional update of a temp, or a series of packed writes. The easiest
solution seems to be to require that nir_store_dest()'s arg comes from an
SSA temp.
This causes us to put in a few more temporary MOVs in the NIR SSA dest
case, but copy propagation successfully cleans those up.
The shader-db change is modest:
total instructions in shared programs: 93774 -> 93598 (-0.19%)
instructions in affected programs: 14760 -> 14584 (-1.19%)
total estimated cycles in shared programs: 212135 -> 211946 (-0.09%)
estimated cycles in affected programs: 27005 -> 26816 (-0.70%)
but I was seeing patterns in some register-allocation failures in DEQP
tests that looked like the extra MOVs would increase maximum register
pressure in loops. Some debug code indicates that that's not the case,
though I'm still a bit confused by that result.

One tiny hack is left in vc4_bufmgr.c for what kind of mapping we got so
that we can free it.
|
|
|
|
|
|
| |
Now we aren't limited to 256MB total allocated across a driver instance,
just 256MB at one time. We're still copying in and out, which should get
fixed.

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.

The loop is scanning until the original max_ip (size of the BO), but we
want to not examine any code after the PROG_END's delay slots. There was
a block trying to do that, except that we had some early continue
statements if the signal wasn't a PROG_END or a BRANCH.
The failure mode would be that a valid shader is rejected because some
undefined memory after the PROG_END slots is parsed as a branch and the
rest of its setup is illegal. I haven't seen this in the wild, but
valgrind was complaining and the new userland simulator code started
triggering it.

A constant value of float type is not necessarily a ConstantFP: it could also
be a constant expression that for some reason hasn't been folded.
This fixes a regression in GL45-CTS.arrays_of_arrays_gl.InteractionFunctionCalls2

Long story short, 3D and CP are aliased on Fermi and initializing
compute after pushing the MS sample coordinate offsets seems to
corrupt 3D state for weird reasons.
I still don't have the faintest clue what is going on, but
this seems to only affect Fermi generation. A possible fix
could be to use two different channels, one for 3D and one
for CP.
This fixes a bunch of regressions pinpointed by piglit.

With ARB_gpu_shader5, texture offsets can be any source, including TEMPs
and IN's. Make sure to process them as regular sources so that we pick
up masks, etc.
This should fix some CTS tests that feed offsets directly to
textureGatherOffset, and we were not picking up the input use, thus not
advertising it in the shader header.

These constant value VS PARAM exports:
- 0,0,0,0
- 0,0,0,1
- 1,1,1,0
- 1,1,1,1
can be loaded into PS inputs using the DEFAULT_VAL field, and the VS exports
can be removed from the IR to save export & parameter memory.
After LLVM optimizations, analyze the IR to see which exports are equal to
the ones listed above (or undef) and remove them if they are.
Targeted use cases:
- All DX9 eON ports always clear 10 VS outputs to 0.0 even if most of them
are unused by PS (such as Witcher 2 below).
- VS output arrays with unused elements that the GLSL compiler can't
eliminate (such as Batman below).
The shader-db deltas are quite interesting:

The per-element fetch has quite some calculations which are constant,
these can be moved outside both the per-element as well as the main
shader loop (llvm can figure out it's constant mostly on its own, however
this can have a significant compile time cost).
Similarly, it looks easier swapping the fetch loops (outer loop per attrib,
inner loop filling up the per vertex elements - this way the aos->soa
conversion also can be done per attrib and not just at the end though again
this doesn't really make much of a difference in the generated code). (This
would also make it possible to vectorize the calculations leading to the
fetches.)
There's also some minimal change simplifying the overflow math slightly.
All in all, the generated code seems to look slightly simpler (depending
on the actual vs), but more importantly I've seen a significant reduction
in compile times for some vs (albeit with old (3.3) llvm version, and the
time reduction is only really for the optimizations run on the IR).
v2: adapt to other draw change.
No changes with piglit.

Previous attempts to zero initialize all inputs were not really optimal
(though no performance impact was measurable). In fact this is not really
necessary, since we know the max number of inputs used.
Instead, just generate fetch for up to max inputs used by the shader,
directly replacing inputs for which there was no vertex element by zero.
This also cleans up key generation, which previously would have stored
some garbage for these elements.
And also drop the assertion which indicates such bogus usage by a
debug_printf (the whole point of initializing the undefined inputs was to
make this case safe to handle).

For the texturing packs, things looked pretty terrible. For every
lerp, we were repacking the values, and while those look sort of cheap
with 128bit, with 256bit we end up with 2 of them instead of just 1 but
worse, plus 2 extracts too (the unpack, however, works fine with a
single instruction, albeit only with llvm 3.8 - the vpmovzxbw).
Ideally we'd use more clever pack for llvmpipe backend conversion too
since we actually use the "wrong" shuffle (which is more work) when doing
the fs twiddle just so we end up with the wrong order for being able to
do native pack when converting from 2x8f -> 1x16b. But this requires some
refactoring, since the untwiddle is separate from conversion.
This is only used for avx2 256bit pack/unpack for now.
Improves openarena scores by 8% or so, though overall it's still pretty
disappointing how much faster 256bit vectors are even with avx2 (or
rather, aren't...). And, of course, eliminating the needless
packs/unpacks in the first place would eliminate most of that advantage
(not quite all) from this patch.

During dual instance encoding submission, if the second encode task and first
encode task have no reference dependency, e.g. p following with idr-frame,
there is a chance the second task will use for its reconstructed picture
buffer the same buffer used by first task for its reference/reconstructed
picture. In this case, buffer corruption may occur depending on encoding
speed. Fix is to force flush these two tasks separately to avoid race condition

Reminiscent from the pre-loader days, were we had multiple instances of
the loader logic in separate places and one could build a "GALLIUM_ONLY"
version.
Since that is no longer the case and the loaders (glx/egl/gbm) do not
(and should not) require to know any classic/gallium specific we can
drop the argument and the related code.
