glsl: Make copy propagation not panic when it sees an intrinsic.
A number of games have large arrays of constants, which we promote to
uniforms. This introduces copies from the uniform array to the original
temporary array. Normally, copy propagation eliminates those copies,
making everything refer to the uniform array directly.
A number of shaders in "Deus Ex: Mankind Divided" recently exposed a
limitation of copy propagation - if we had any intrinsics (i.e. image
access in a compute shader), we weren't able to get rid of these copies.
That meant that any variable indexing remained on the temporary array
rather being moved to the uniform array. i965's scalar backend
currently doesn't support indirect addressing of temporary arrays,
which meant lowering it to if-ladders. This was horrible.
According to Marek, on radeonsi/GCN, "F1 2015" uses 64% less
spilled-temp-array memory.
On i965/Skylake:
total instructions in shared programs:
13362954 ->
13329878 (-0.25%)
instructions in affected programs: 43745 -> 10669 (-75.61%)

i965: Make DCE set null destinations on messages with side effects.
(Co-authored by Matt Turner.)
Image atomics, for example, return a value - but the shader may not
want to use it. We assigned a useless VGRF destination. This seemed
harmless, but it can actually be quite harmful. The register allocator
has to assign that VGRF to a real register. It may assign the same
actual GRF to the destination of an instruction that follows soon after.
This results in a write-after-write (WAW) dependency, and stall.
A number of "Deus Ex: Mankind Divided" shaders use image atomics, but
don't use the return value. Several of these were hitting WAW stalls
for nearly 14,000 (poorly estimated) cycles a pop. Making dead code
elimination null out the destination avoids this issue.
This patch cuts one shader's estimated cycles by -98.39%! Removing the
message response should also help with data cluster bandwidth.

Curro pointed out that FS_OPCODE_FB_WRITE has a null destination and
actually writes the flag on Gen4-5 to dynamically decide whether to
write some payload data. The hunk removed in this patch might have
NOP'd it, except that we don't actually mark flags_written() in the

nvc0: enable FBFETCH with a special slot for color buffer 0
We don't need to support all the color buffers for advanced blend, just
cb0. For Fermi, we use the special binding slots so that we don't
overlap with user textures, while Kepler+ gets a dedicated position for
the fb handle in the driver constbuf.
This logic is only triggered when a FBFETCH is actually present so it
should be a no-op most of the time.

i965: Move Gen4-5 interpolation stuff to brw_wm_prog_data.
This fixes glxgears rendering, which had surprisingly been broken since
late October! Specifically, commit
91d61fbf7cb61a44adcaae51ee08ad0dd6b.
glxgears uses glShadeModel(GL_FLAT) when drawing the main portion of the
gears, then uses glShadeModel(GL_SMOOTH) for drawing the Gouraud-shaded
inner portion of the gears. This results in the same fragment program
having two different state-dependent interpolation maps: one where
gl_Color is flat, and another where it's smooth.
The problem is that there's only one gen4_fragment_program, so it can't
store both. Each FS compile would trash the last one. But, the FS
compiles are cached, so the first one would store FLAT, and the second
would see a matching program in the cache and never bother to compile
one with SMOOTH. (Clearing the program cache on every draw made it
render correctly.)
Instead, move it to brw_wm_prog_data, where we can keep a copy for
every specialization of the program. The only downside is bloating
the structure a bit, but we can tighten that up a bit if we need to.
This also lets us kill gen4_fragment_program entirely!

anv: Default PointSize to 1.0 if not written by the shader
The Vulkan rules for point size are a bit whacky. If you only have a
vertex shader and you use points, then you must write PointSize in your
vertex shader. If you have a geometry or tessellation shader, then it's
dependent on the shaderTessellationAndGeometryPointSize device feature.
From the Vulkan 1.0.38 specification:
"shaderTessellationAndGeometryPointSize indicates whether the
PointSize built-in decoration is available in the tessellation
control, tessellation evaluation, and geometry shader stages. If this
feature is not enabled, members decorated with the PointSize built-in
decoration must not be read from or written to and all points written
from a tessellation or geometry shader will have a size of 1.0. This
also indicates whether shader modules can declare the
TessellationPointSize capability for tessellation control and
evaluation shaders, or if the shader modules can declare the
GeometryPointSize capability for geometry shaders. An implementation
supporting this feature must also support one or both of the
tessellationShader or geometryShader features."
In other words, if the feature is disbled (the client can disable
features!) then they don't write PointSize and we provide a 1.0 default
but if the feature is enabled, they do write PointSize and we use the
one they wrote in the shader. There are at least two valid ways we can
implement this:
1) Track whether or not shaderTessellationAndGeometryPointSize is
enabled and set the 3DSTATE_SF bits based on that and what stages
are enabled, ignoring the shader source.
2) Just look at the last geometry stage VUE map and see if they wrote
PointSize and set the 3DSTATE_SF accordingly.
The second solution is the easiest and the most robust against invalid
usage of the Vulkan API, so we choose to go with that one.
This fixes all of the dEQP-VK.tessellation.primitive_discard.*point_mode
tests. The tests are also broken because they unconditionally enable
shaderTessellationAndGeometryPointSize if it's supported by the
implementation and then don't write PointSize in the evaluation shader.
However, since this is the "robust against invalid API usage" solution,
the tests happily pass. :-)

i915: Add XRGB8888 format to intel_screen_make_configs
This is a copy of commit
536003c11e4cb1172c540932ce3cce06f03bf44e
except for i915.
Original log for the i965 commit follows:
Some application, such as drm backend of weston, uses XRGB8888 config as
default. i965 doesn't provide this format, but before commit
65c8965d,
the drm platform of EGL takes ARGB8888 as XRGB8888. Now that commit
65c8965d makes EGL recognize format correctly so weston won't start
because it can't find XRGB8888. Add XRGB8888 format to i965 just as
other drivers do.

gbm/drm: Pick the oldest available buffer in get_back_bo
Applications may query the back buffer age to efficiently perform
partial updates. Generally the application will keep a fixed length
damage history, and use this to calculate what needs to be redrawn
based on the age of the back buffer it's about to render to.
If presented with a buffer that has an age greater than the
length of the damage history, the application will likely have
to completely repaint the buffer.
Our current buffer selection strategy is to pick the first available
buffer without considering its age. If an application frequently
manages to fit within two buffers but occasionally requires a third,
this extra buffer will almost always be old enough to fall outside
of a reasonably long damage history, and require a full repaint.
This patch changes the buffer selection behaviour to prefer the oldest
available buffer.
By selecting the oldest available buffer, the application will likely
always be able to use its damage history, at a cost of having to
perform slightly more work every frame. This is an improvement if
the cost of a full repaint is heavy, and the surface damage between
frames is relatively small.
It should be noted that since we don't currently trim our queue in
any way, an application that briefly needs a large number of buffers
will continue to receive older buffers than it would if it only ever
needed two buffers.
