(cherry picked from commit 3610b1466d)
Our driver uses the brw_render_cache mechanism to track buffers we've
rendered to and are about to sample from.
Previously, we did a single PIPE_CONTROL with the following bits set:
- Render Target Flush
- Depth Cache Flush
- Texture Cache Invalidate
- VF Cache Invalidate
- Instruction Cache Invalidate
- CS Stall
This combined both "top of pipe" invalidations and "bottom of pipe"
flushes, which isn't how the hardware is intended to be programmed.
The "top of pipe" invalidations may happen right away, without any
guarantees that rendering using those caches has completed. That
rendering may continue altering the caches. The "bottom of pipe"
flushes do wait for the rendering to complete. The CS stall also
prevents further work from happening until data is flushed out.
What we wanted to do was wait for rendering complete, flush the new
data out of the render and depth caches, wait, then invalidate any
stale data in read-only caches. We can accomplish this by doing the
"bottom of pipe" flushes with a CS stall, then the "top of pipe"
flushes as a second PIPE_CONTROL. The flushes will wait until the
rendering is complete, and the CS stall will prevent the second
PIPE_CONTROL with the invalidations from executing until the first
is done.
Fixes dEQP-GLES3.functional.texture.specification.teximage2d_pbo
subtests on Braswell and Skylake. These tests hit the meta PBO
texture upload path, which binds the PBO as a texture and samples
from it, while rendering to the destination texture. The tests
then sample from the texture.
For now, we leave Gen4-5 alone. It probably needs work too, but
apparently it hasn't even been setting the (G45+) TC invalidation
bit at all...

(cherry picked from commit adb40a7399)
In "manual" derivative mode (always used on nv50 and sometimes on nvc0
but always for cube), the idea is that using the quadop instruction, we
set up the "other" quads to have values such that the derivatives work
out, and then run the texture instruction as if nothing were strange. It
pulls values from the other lanes, and does its magic.
However cube coordinates have to be normalized - one of the 3 coords has
to be 1, to determine which is the major axis, to say which face is
being sampled. We were normalizing the coordinates first, and then
adding the derivatives. This is wrong for two reasons:
- the coordinates got normalized by a scaling factor but the
derivatives didn't
- the result of the addition didn't end up normalized
To resolve this, we flip the logic around to normalize *after* the
per-lane coordinates are set up.
This fixes a bunch of textureGrad cube dEQP tests.
NOTE: nv50 cube arrays with explicit derivatives are still broken, to be
resolved at a later date.

(This is commit 4a1c8a3037 for vec4 mode.)
Using the push model for inputs is much more efficient than pulling
inputs - the hardware can simply copy a large chunk into URB registers
at thread creation time, rather than having the thread send messages to
request data from the L3 cache. Unfortunately, it's possible to have
more TES inputs than fit in registers, so we have to fall back to the
pull model in some cases.
However, it turns out that most tessellation evaluation shaders are
fairly simple, and don't use many inputs. An arbitrary cut-off of
24 vec4 slots (12 registers) should suffice. (I chose this instead of
the 32 vec4 slots used in the scalar backend to avoid regressing a few
Piglit tests due to the vec4 register allocator being too stupid to
figure out what to do. We probably ought to fix that, but it's a
separate issue.)
