6984a6be5c meta: Eliminate samplers[] array in favor of using vec4_prefix.
We don't need an array mapping the shader index to "sampler2DMS",
"isampler2DMS", and so on.  We can simply do "%ssampler2DMS" and pass in
vec4_prefix, which is "", "i", or "u".

This eliminates the use of C99 array initializers and should fix the
MSVC build.

119aa50929 i965: Delete the fabulous target_to_target() function.
gl_texture_object's Target field is never a cube face enumeration, so
target_to_target is just the identity function.  Aptly named, at least.

I verified this by putting an assert(!"ZOMG, CUBES!") in the cube face
case, and running Piglit.  Nothing ever hit it.  Beyond that, I
inspected the code in mesa/main.

This could probably also be deleted from i915, but I haven't tested
there.

82f9ad8c60 i965: Fix S8 and X8 reversal in brw_depthbuffer_format refactor.
In commit 09d9a8913e, I accidentally
botched the X8 and S8 cases.  (I wrote this patch before realizing that
X8 and S8 had been swapped in the big MESA_FORMAT rename, and apparently
didn't rebase it properly after fixing that...)

Fixes regressions in 13 Piglit tests on Ironlake.

Commit 46d3c2bf4d accidentally moved
the call to brw_init_state() before creating a hardware context.
This meant brw_upload_initial_gpu_state would always early return.
Except on Gen6+, we stopped uploading the initial GPU state via
state atoms, so it never happened.

Fixes a regression since 46d3c2bf4d.

e3823147a5 i965/fs: Implement scratch read/write support for Broadwell.
To make sure that both the Gen4 and Gen7 style messages work, I
initially disabled the SHADER_OPCODE_GEN7_SCRATCH_READ optimization,
ran Piglit, re-enabled it, and ran Piglit again.  Both worked fine.

Fixes 40 Piglit tests (most of the varying-packing category).

v2: Move num_regs assertion from gen8_fs_generator to
    gen8_set_dp_scratch_message() (suggested by Eric).

The new accessors will make it easy to do Gen7-style scratch messages.

a5e54c91a3 i965: Store absolute thread count in max_wm_threads on Broadwell.
In the past, 3DSTATE_PS took an absolute number of threads.  Conversely,
on Broadwell you always program 64, and it implicitly scales based on
the GT-level with no special programming.  So, I stored 64 in
brw_device_info::max_wm_threads.

However, I didn't realize that we also use max_wm_threads to compute the
size of the scratch space buffer.  In that case, we really need the
absolute number of threads.

This patch hardcodes 3DSTATE_PS to use the value it expects, and changes
max_wm_threads back to a (completely fake) absolute thread count (once
again copied from Haswell).

dca84b4b5b i965: Use MOV, not OR for setting URB write channel enables on Gen8+.
On Broadwell, g0.5 contains the "Scratch Space Pointer"; using OR
puts some bits of that into "ignored" sections of our message header.

While this doesn't hurt, it's also not terribly /useful/.  Using MOV
is sufficient to set the only interesting bits in this part of the
message header.
