We're going to use UBO loads for implementing YUV linear-to-T-format
blits.
|
| |
|
|
|
| |
This keeps us from promoting them up to 8888, at the cost of not being
color-renderable.

I was overwriting view->texture with the shadow resource when we need to
do shadow copies (retiling or baselevel rebase), but that tripped up some
critical new sanity checking in state_tracker (making sure that stObj->pt
hasn't changed from view->texture through TexImage-related paths).
To avoid that, move the shadow resource to the vc4_sampler_view struct.

This is a preparation step for having multiple jobs being queued up at the
same time.

We were baking in the LOD of the source level to each shader. Instead,
pass it in as a uniform -- this requires storing it to a temp register,
but that's better than compiling a ton of separate shaders:
total instructions in shared programs: 115032 -> 115036 (0.00%)
instructions in affected programs: 96 -> 100 (4.17%)
LOST: 572

The ranges are in units of bytes, not dwords. This wasn't caught by
piglit tests because ttn tends to make one big uniform file, so we only
had one UBO range with a src and dst offset of 0.

The compiler uses the per-stage flags already, so it didn't need this.
vc4_uniforms was using it, so just replace it with both of the stage flags
for now.

If a block might be entered from multiple locations, then the uniform
stream will (probably) be at different points, and we need to make sure
that it's pointing where we expect it to be. The kernel also enforces
that any block reading a uniform resets uniforms, to prevent reading
outside of the uniform stream by using looping.

Use PIPE_SWIZZLE_* everywhere.
Use X/Y/Z/W/0/1 instead of RED, GREEN, BLUE, ALPHA, ZERO, ONE.
The new enum is called pipe_swizzle.

This is the core of ARB_texture_multisample. Most of the piglit tests for
GL_ARB_texture_multisample require GL 3.0, but exposing support for this
lets us use the gallium blitter for multisample resolves. We can
sometimes multisample resolve using just the RCL, but that requires that
the blit is 1:1, unflipped, and aligned to tile boundaries.

We can't do this all the time, because you want blending to be done in
linear space, and sRGB would lose too much precision being done in 4x8.
The win on instructions is pretty huge when you can, though.
total uniforms in shared programs: 32065 -> 32168 (0.32%)
uniforms in affected programs: 327 -> 430 (31.50%)
total instructions in shared programs: 92644 -> 89830 (-3.04%)
instructions in affected programs: 15580 -> 12766 (-18.06%)
Improves openarena performance at 1920x1080 from 10.7fps to 11.2fps.

This massively reduces our dependency on VC4-specific optimization passes.
shader-db:
total uniforms in shared programs: 32077 -> 32067 (-0.03%)
uniforms in affected programs: 149 -> 139 (-6.71%)
total instructions in shared programs: 98208 -> 98182 (-0.03%)
instructions in affected programs: 2154 -> 2128 (-1.21%)

It's a bunch of work for us to emit it (and its uniforms), more work for
the kernel to validate it, and additional work for the CLE to read
it. Improves es2gears framerate by about 50%.

Cuts another 12% of vc4_uniforms.o, in exchange for computing it at
CSO creation time.
|
| |
|
|
|
| |
In exchange for a bit of space and computation in CSO setup, we cut
vc4_uniform.c (draw time) code size by 4.8%.
|
|
|
The rest of vc4_program.c is about compiling, while this is about
uniform emit at draw time.
