The idea was that we could skip uploading the constant-indexed uniform
data and just upload the uniforms that are variably-indexed. However,
since the VS bin and render shaders may have a different set of uniforms
used, this meant that we had to upload the UBO for each of them. The
first case is generally a fairly small impact (usually the uniform array
is the most space, other than a couple of FSes in shader-db), while the
second is a larger impact: 3DMMES2 was uploading 38k/frame of uniforms
instead of 18k.
Given that the optimization is of dubious value, has a big downside, and
is quite a bit of code, just drop it. No change in shader-db. No change
on 3DMMES2 (n=15).
We'd end up with the constant offset in the uniform stream anyway, since
they're bigger than small immediates. Avoids the extra uniforms and adds
in the shader in favor of just adding once on the CPU.
shader-db:
total instructions in shared programs: 6496865 -> 6494851 (-0.03%)
total uniforms in shared programs: 2119511 -> 2117243 (-0.11%)
I want to reuse this for encoding small constant UBO/SSBO offsets into the
uniform stream to reduce the extra uniform loads and adds for the small
constant offsets.

I added new barrier bits in 220c1dce1e
and made most drivers skip them. I thought nvc0 was already skipping
those but missed the else case here, which does something. So make it
explicitly skip like I did everywhere else.
Thanks to Ilia for catching this.
Fixes: 220c1dce1e gallium: Add PIPE_BARRIER_UPDATE_BUFFER and UPDATE_TEXTURE bits.
The glMemoryBarrier() function makes shader memory stores ordered with
respect to things specified by the given bits. Until now, st/mesa has
ignored GL_TEXTURE_UPDATE_BARRIER_BIT and GL_BUFFER_UPDATE_BARRIER_BIT,
saying that drivers should implicitly perform the needed flushing.
This seems like a pretty big assumption to make. Instead, this commit
opts to translate them to new PIPE_BARRIER bits, and adjusts existing
drivers to continue ignoring them (preserving the current behavior).
The i965 driver performs actions on these memory barriers. Shader
memory stores go through a "data cache" which is separate from the
render cache and other read caches (like the texture cache). All
memory barriers need to flush the data cache (to ensure shader memory
stores are visible), and possibly invalidate read caches (to ensure
stale data is no longer visible). The driver implicitly flushes for
most caches, but not for data cache, since ARB_shader_image_load_store
introduced MemoryBarrier() precisely to order these explicitly.
I would like to follow i965's approach in iris, flushing the data cache
on any MemoryBarrier() call, so I need st/mesa to actually call the
pipe->memory_barrier() callback.
Fixes KHR-GL45.shader_image_load_store.advanced-sync-textureUpdate
and Piglit's spec/arb_shader_image_load_store/host-mem-barrier on
the iris driver.
Roland said this looks reasonable to him.

This allows DRI3 to pick between UIF and raster according to whether we're
pageflipping or not and whether the pageflipping display can do UIF,
avoiding copies for the windowed/composited case that previously was
forced to linear.
Improves windowed glmark2 -b build:use-vbo=false performance by 30.7783%
+/- 13.1719% (n=3)
We ask the other side to make a buffer with the right number of pages, and
then just store the UIF in it. This avoids an extra silent copy of the
buffer from linear to UIF if it gets used for texturing (X11 copy-based
swapbuffers, GL compositors).
Fix this check so that we can get a HiZ aux buffer for multisampled
surfaces as well. Also make sure we don't try to emit a sampler view
surface state for multisampled depth sufaces with HiZ enabled, as
the sampler can't HiZ for multisampled buffers and isl would assert.

There are two stages to varying assembly in the command stream: creating
the varying buffers in the command stream, and creating the varying meta
descriptors (also in the command stream) linked to the aforementioned
buffers. The previous code for this was ad hoc and brittle, making some
invalid assumptions causing unmaintainable workarounds to pile up across
the driver (both compiler and command stream side).
This patch completely rewrites the varying assembly code. There's a
trivial performance penalty (we now memcpy the varying meta to the
command stream on draw, rather than on compile). That said, the
improvement in flexibility and clarity is well-worth it.
The motivator for these changes was support for gl_PointCoord (and
eventually point sprites for legacy GL), which was impossible to
implement with the old varying assembly code. With the new refactor,
it's super easy; support for gl_PointCoord is included with this patch.
All in all, I'm quite happy with how this turned out.
