NIR brings us better optimization than I would have bothered to write
within the driver, developers sharing future optimization work, and the
ability to share device-specific lowering code that we and other
GLES2-level drivers need.
total uniforms in shared programs: 13421 -> 13422 (0.01%)
uniforms in affected programs: 62 -> 63 (1.61%)
total instructions in shared programs: 39961 -> 39707 (-0.64%)
instructions in affected programs: 15494 -> 15240 (-1.64%)
v2: Add missing imov support, and assert that there are no dest saturates.
v3: Rebase on the target-specific algebraic series.
v4: Rebase on gallium-includes-from-NIR changes in mater.
v5: Rebase on variables being in lists instead of hash tables.
v6: Squash in intermediate changes that used the NIR-to-TGSI pass (which
I'm not committing)
The only hackish ones are llvmpipe and softpipe, which currently return
the same string as for get_vendor(), while ideally they should return
the CPU vendor.

Resolving a multisampled depth texture into
a single sampled texture is supported on >= SM4.1
hw. It is possible some previous hw support it.
The ability was tested on radeonsi and nvc0.
Apparently is is also supported for radeon >= r700.
This patch adds the MULTISAMPLE_Z_RESOLVE cap and
add it to the drivers. It is advertised for drivers
for which it is sure the ability is supported.

Since our kernel BOs require CMA allocation, and the use of them requires
new mmaps, it's pretty expensive and we should avoid it if possible.
Copying my original design for Intel, make a userspace cache that reuses
BOs that haven't been shared to other processes but frees BOs that have
sat in the cache for over a second.
Improves glxgears framerate on RPi by around 30%.
This gets DRI3 working on modesetting with glamor. It's not enabled under
simulation, because it looks like handing our dumb-allocated buffers off
to the server doesn't actually work for the server's rendering.
Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not
supporting vertex ids with base vertex offset applied (so, only support
d3d10-style vertex ids) will get such a d3d10-style vertex id instead -
with the caveat they'll also need to handle the basevertex system value
too (this follows what core mesa already does).
Additionally, this is also useful for other state trackers (for instance
llvmpipe / draw right now implement the d3d10 behavior on purpose, but
with different semantics it can just do both).
Doesn't do anything yet.
And fix up the docs wrt similar values.
v2: incorporate feedback from Brian and others, better names, better docs.

With 5 shader stages and various combinations of enabled and disabled shaders,
the maximum number of outputs in one shader doesn't have to be equal to
the maximum number of inputs in the following shader.
v2: return 32 for softpipe and llvmpipe
There are only 32 bits in the flatshade flags (which are 1 bit per
component), the simulator crashes when you use more than about this many
varyings, and the original Broadcom code drop only exposed 8 as well.
Fixes 26 piglit tests in the varying-packing group, and makes many others
go from crash to fail (due to not checking their varying counts and
treating link failures as failures). Regresses ARB_fp/minmax (due to 8
varyings instead of 10).
This gets a ton of piglit working that crashes in waffle context
management stuff otherwise. Actually supporting mismatched FB sizes is at
best going to require some more load/store generals for color buffers, but
if I can't manage to do that I'll want to just have state_tracker reject
those FBOs as unsupported, rather than deny GL 2.1.
We don't have any specific limits in the hardware, just like the other
GPUs, so match their behavior. Fixes minmax_gles2 and several other
piglit tests relying on the specced uniform minmax values.
This allows a sampler view to have a different texture target than the
underlying resource. This will be used to implement the type casting
between 2d arrays and cube maps as specified in ARB_texture_view.

There were troubles with bools without using native integers
(st_glsl_to_tgsi seemed to think bool true was 1.0f sometimes, when as a
uniform it's stored as ~0), and since I've got native integers other than
divide, I might as well just support them.
Now that tiling is in place, we can expose the other formats. Depth is
still broken (need to make changes in the shader), but if you don't expose
it things crash all over. SNORM is dropped, but we could re-add it later
with some shader fixes to handle converting between [0,1] and [-1,1].
This still treats everything as RGBA8888 for the most part, same as
before. This is a prerequisite for handling other texture formats, since
only RGBA8888 has a raster-layout mode.
We don't actually do them (or even fake them) currently, but it does get
us a bunch of unrelated glean glsl1 tests passing, which previously would
error out due to glean assuming the minimums on a 3D texture that 2 of the
subtests use.
This can be useful for looking at context init setup and texture format
choices, and there's no reason for the silly retval computation we do if
you're not going to have this code (mostly from freedreno) around.
