In addition to the DRM interface in active development, for legacy
kernels Panfrost has a small, optional, out-of-tree glue repository. For
various reasons, this legacy code should not be included in Mesa proper,
but this commit allows it to coexist peacefully with upstream Panfrost.
If the nondrm repo is cloned/symlinked to the directory
`src/gallium/drivers/panfrost/nondrm`, legacy functionality will be
built. Otherwise, the driver will build normally, though a runtime error
message will be printed if a legacy kernel is detected.
This workaround is icky, but it allows a nearly-upstream Panfrost to
work on real hardware, today. Ideally, this patch will be reverted when
the Panfrost kernel module is mature and we drop legacy support.

As kmsro allows an essentially mix-and-match hodgepodge of display
drivers and renderonly GPUs, it doesn't make sense to couple the display
driver entrypoint definition with the driver. Instead, we move *all*
kmsro entrypoints to a shared kmsro block at the end (avoiding clutter
and distraction since this list may snowball in the future).

The strategy is to keep a CPU-side counter of the direct invocations,
and a GPU-side counter of the indirect invocations, and then add them
together for queries.
The specific technique is a macro which multiplies a list of integers
together and accumulates the product into SCRATCH registers held inside
of the context. Another macro will read those values out and add them to
the passed-in cpu-side counter to be stored in a query buffer the same
way that all the other statistics are stored.
Original implementation by Rhys Perry, redone by Ilia Mirkin to use the
SCRATCH temporaries.

For the NO_WAIT variants, we would jump into the ALWAYS case for both
nested and inverted occlusion queries. However if the query had
previously completed, the application could reasonably expect that the
render condition would follow that result.
To resolve this, we remove the nesting distinction which unnecessarily
created an imbalance between the regular and inverted cases (since
there's no "zero" condition mode). We also use the proper comparison if
we know that the query has completed (which could happen as a result of
an earlier get_query_result call).

Looks like SUBFM.3D and SUEAU are perfectly capable of dealing with 3d
tiling, they just need the correct inputs. Supply them.
We also have to deal with the case where a 2d "layer" of a 3d image is
bound. In this case, we supply the z coordinate separately to the
shader, which has to optionally treat every 2d case as if it could be a
slice of a 3d texture.

We used to pre-set a bunch of extra arguments to a texture instruction
in order to force the RA to allocate a register at the boundary of 4.
However with the levelZero optimization, which removes a LOD argument
when it's uniformly equal to zero, we undid that logic by removing an
extra argument. As a result, we could end up with insufficient alignment
on the second wide texture argument.
Instead we switch to a different method of achieving the same result.
The logic runs during the constraint analysis of the RA, and adds unset
sources as necessary right before being merged into a wide argument.
Fixes MISALIGNED_REG errors in Hitman when run with bindless textures
enabled on a GK208.

Atomic operations don't update the local cache, which means that we
would have to issue CCTL operations in order to get the updated values.
When we know that a buffer is primarily used for atomic operations, it's
easier to just avoid the caching at that level entirely.
The same issue persists for non-atomic buffers, which will have to be
fixed separately.

The hardware does not natively support FIXED and DOUBLE formats. If
those are used in an indirect draw, they have to be converted. Our
conversion tries to be clever about only converting the data that's
needed. However for indirect, that won't work.
Given that DOUBLE or FIXED are highly unlikely to ever be used with
indirect draws, read the indirect buffer on the CPU and issue draws
directly.

`EGLDisplay` variables (the opaque Khronos type) have mostly been
consistently called `dpy`, as this is the name used in the Khronos
specs.
However, `_EGLDisplay` variables (our internal struct) have been
randomly called `dpy` when there was no local variable clash with
`EGLDisplay`s, and `disp` otherwise.
Let's be consistent and use `dpy` for the Khronos type, and `disp`
for our struct.

I had a single function for "does this do float input unpacking" with two
major flaws: It was missing the most common thing to try to copy propagate
a f32 input nunpack to (the VFPACK to an FP16 render target) along with
several other ALU ops, and also would try to propagate an f32 unpack into
a VFMUL which only does f16 unpacks.
instructions in affected programs: 659232 -> 655895 (-0.51%)
uniforms in affected programs: 132613 -> 135336 (2.05%)
and a couple of programs increase their thread counts.
The uniforms hit appears to be a pattern in generated code of doing (-a >=
a) comparisons, which when a is abs(b) can result in the abs instruction
being copy propagated once but not fully DCEed.
If you only bound rt 1+, we'd still emit a write to the rt0 that isn't
present (noticed while debugging an
ext_framebuffer_multisample-alpha-to-coverage-no-draw-buffer-zero
regression in another change).
Iris would like to use compact arrays for tesslevels and clip/cull
distances. radeonsi will likely want to switch to these at some point,
since it'll be necessary for GL_ARB_gl_spirv support, but it's not ready
for them just yet.
