panfrost: Backport driver to Mali T600/T700
There are a few differenes between Mali T860 (Panfrost's primary
reference target) and the older Midgard generations (T600/T700):
- Miscellaneous different magic numbers. It's not clear what these
numbers mean on either the old or new configurations yet.
- Errata fixes. T800 is the final Midgard generation and presumably the
least buggy. Older Midgard has some extra hardware errata we have to
workaround.
- SFBD vs MFBD split. Essentially, older Midgard use a Single
FrameBuffer Descriptor (SFBD), which corresponds to single
render-target rendering. Newer Midgard (T760+) use a Multiple
FrameBuffer Descriptor (MFBD), allowing multiple RTs. On ES 2.0, these
descriptors serve the same function, but we implement both, depending on
the version of the hardware.
- CPU bitness. 32-bit systems generally use 32-bit GPU descriptors, and
vice versa for 64-bit. Our target T760 systems are 32-bit whereas our
target T860 systems are 64-bit. More work is needed in this area.
This patch fixes support in these areas for supporting older Midgard
hardware. It is tested on Mali T760 and Mali T860.

nir: Gather texture bitmasks in gl_nir_lower_samplers_as_deref.
Eric and I would like a bitmask of which samplers are used, similar to
prog->SamplersUsed, but available in NIR. The linker uses SamplersUsed
for resource limit checking, but later optimizations may eliminate more
samplers. So instead of propagating it through, we gather a new one.
While there, we also gather the existing textures_used_by_txf bitmask.
Gathering these bitfields in nir_shader_gather_info is awkward at best.
The main reason is that it introduces an ordering dependency between the
two passes. If gathering runs before lower_samplers_as_deref, it can't
look at var->data.binding. If the driver doesn't use the full lowering
to texture_index/texture_array_size (like radeonsi), then the gathering
can't use those fields. Gathering might be run early /and/ late, first
to get varying info, and later to update it after variant lowering. At
this point, should gathering work on pre-lowered or post-lowered code?
Pre-lowered is also harder due to the presence of structure types.
Just doing the gathering when we do the lowering alleviates these
ordering problems. This fixes ordering issues in i965 and makes the
txf info gathering work for radeonsi (though they don't use it).

radeonsi uses variable dereferences for samplers rather than

st/mesa: Limit GL_MAX_[NATIVE_]PROGRAM_PARAMETERS_ARB to 2048
Piglit's vp-max-array test creates a vertex program containing a uniform
array sized to the value of GL_MAX_NATIVE_PROGRAM_PARAMETERS_ARB. Mesa
will then add additional state-var parameters for things like the MVP
matrix.
radeonsi currently exposes a value of 4096, derived from constant buffer
upload size. This means the array will have 4096 elements, and the
extra MVP state-vars would get a prog_src_register::Index of over 4096.
Unfortunately, prog_src_register::Index is a signed 13-bit integer, so
values beyond 4096 end up turning into negative numbers. Negative
source indexes are only valid for relative addressing, so this ends up
generating illegal IR.
In prog_to_nir, this would cause an out of bounds array access.
st_mesa_to_tgsi checks for a negative value, assumes it's bogus,
and remaps it to parameter 0 in order to get something in-range.
This isn't right - instead of reading the MVP matrix, it would read
the first element of the vertex program's large array. But the test
only checks that the program compiles, so we never noticed that it
was broken.
This patch limits the size of the program limits, with the understanding
that we may need to generate additional state-vars internally. i965 has
exposed 1024 for this limit for years, so I don't expect lowering it to
2048 will cause any practical problems for radeonsi or other drivers.

Because the intel_dump_gpu tool wasn't making any distinction between
