This is the support for both the global and per-vertex modes.

I don't see piglit tests for it, but this should be better than not
emitting it at all.

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.

This query has always been useless, but we could potentially reject
well-formed, runnable programs if we expose a value that's too low.

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.

After implementing depth stores, it looks like this is the way things
actually are, according to hiz-depth-read-fbo-d24-s0's probes.

It was useful on i965, but it's even more useful for debugging tiled
renderers.

So far, apparently there's been some NULL laying at the address just after
the options anyway, but the next commit changed that.

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.

There are a few tools I want to have always available, and fprintf() and
abort() are among them.

Fixes swapped colors on the copypix demo and some piglit tests like
pbo-teximage-tiling .

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.
|
| |
|

|

We will support more than this eventually, but for now this makes u_vbuf
format-convert a few things (32-bit snorm and scaled, doubles) for us.

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.

This was inherited from freedreno, but doesn't apply to us.

This isn't passing all tests (glsl-fs-fragcoord-zw-ortho, for example),
but it does get a bunch more tests passing.

v2: Fix an accidental deletion of some characters from the copyright
message (caught by Ilia Mirkin)

This mostly just takes every draw call and turns it into a sequence of
commands that clear the FBO and draw a single shaded triangle to it,
regardless of the actual input vertices or shaders. I copied the initial
driver skeleton mostly from freedreno, and I've preserved Rob Clark's
copyright for those. I also based my initial hardcoded shaders and
command lists on Scott Mansell (phire)'s "hackdriver" project, though the
bit patterns of the shaders emitted end up being different.
v2: Rebase on gallium megadrivers changes.
v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change.
v4: Rely on simpenrose actually being installed when building for
simulation.
v5: Add more header duplicate-include guards.
v6: Apply Emil's review (protection against vc4 sim and ilo at the same
time, and dropping the dricommon drm bits) and fix a copyright header
(thanks, Roland)
