811f8a1946 panfrost: Require 64-byte alignment on imports
While Panfrost allocates linear images with strides that are a multiple of 64
bytes, other dma-buf producers on the system may not satisfy this requirement.
However, at least on v7 and newer, any image with a regular format must have a
stride that is a multiple of 64 bytes.

This fixes a real bug in an application that created a linear R8_UNORM image
with stride 480 bytes, imported it as an EGL_image, and then tried to texture
from it with the GPU. Previously, the driver allowed this situation but it
resulted in an imprecise fault from the GPU. This patch corrects the driver to
reject the import as invalid due to the unaligned stride, ensuring we never
attempt to texture from such a resource.

To implement, we add some new layout queries to centralize knowledge about the
stride alignment requirements, and we sprinkle in asserts to show how the
invariant is upheld throughout the lifecycle of image creation to texturing.

1827b4a2db panfrost: Compile indirect dispatch shader on first use
For 2D UI workloads and even most 3D workloads, the indirect dispatch shader
won't actually be needed, but we currently compile it during eglInitialize() on
every v7 application. That hurts app start-up time, especially given that this
shader doesn't hit the disk cache. We can instead defer compiling this shader
until it's actually needed, when glDispatchComputeIndirect() gets called.

The tradeoff is that the first glDispatchComputeIndirect() call will be (much)
slower than successive calls, since we need to build and compile this internal
shader. I'm unconvinced that's a problem in practice.

An app would need to call glDispatchComputeIndirect for the first time in the
middle of a scene.  2D apps never would call that, OpenCL doesn't have that, and
GL compute will have the same costs just moved around.  So it's down to a 3D
GLES3.1 app that indirectly dispatches compute for the first time time in the
middle of a scene. Which, meh? It's not entirely implausible but we have bigger
fish to fry, and this fixes a real problem (about 5% of eglInitialize time spent
building this shader that won't actually get used).

es2_info starts slightly faster with this change.

f8553ef44c panfrost: Remove out-of-band CRC support
Without additional signalling of modifiers, CRCs cannot possibly in a correct
way work across process boundaries. Since we don't do that signalling, we should
not be allocating private CRCs for imported resources, and we should not be
using our own private CRCs for internal resources.

The entire out-of-bands CRC infrastructure is a hack to let us do CRCs even for
imported/exported BOs, but that can't possibly work. Remove it, and remove a
pile of special cases across the driver.

2316b80d77 panfrost: Don't use nir_variable to link varyings
NIR deemphasizes nir_variable. We want to transition off it. Instead of walking
the list of variables and playing games with the GLSL types to collect varying
information, walk the list of instructions and use the I/O semantics to collect
similar information.

In addition to avoiding the reliance on nir_variable, this fixes handling of
struct varyings under certain circumstances. Such programs are compiled by the
GLES3.1 CTS but not used, so without this fix, the affected tests would regress
when precompiling.

1ff3b87ba2 panfrost: Enable rendering to 16-bit and 32-bit
Bifrost onwards handle this in hardware, and the Midgard lowering isn't
too terrible. Enable the format, otherwise desktop GL apps such as
Hacknet try to render to the format and get an incomplete framebuffer.

Cc stable because apparently we've been advertising this format
unintentionally as a result of some other interaction? Unclear how
Hacknet is hitting this, maybe it's an app bug. Shrug, it's not a big
deal regardless.

Additionally, we need to restrict texturing from 32-bit normalized due
to a restriction added with the v7 pixel format fiasco. That means
restricting rendering to 32-bit normalized on v7 onwards.

21a4dbb720 panfrost: Don't use lower_wpos_pntc on Midgard
gl_PointCoord is implemented via a special attribute descriptor on Midgard. This
descriptor has an orientation bit, the orientation is driver-controlled. That
means we can map rast->sprite_coord_mode to this bit, rather than lowering in
the shader.

This is a bug fix for point sprites, which are implemented natively on Midgard
for dubious reasons and need to be flipped this way. It is also an optimization
for apps reading gl_PointCoord, removing the extra arithmetic to flip, although
the value of this is somewhat dubious.

b261a18550 panfrost: Honour flush-to-zero controls on Valhall
Fixes math_bruteforce.atan2 and contractions tests.

For OpenCL, we want to flush fp32 and preserve fp16, applying to both inputs and
outputs so F16_TO_F32 acts as preserve, which implements CL spec text:

> Denormalized numbers for the half data type which may be generated when
converting a float to a half using vstore_half and converting a half to a float
using vload_half cannot be flushed to zero

Note that our libclc builds flush denorms and rusticl does not advertise denorms
so we're expected to flush to zero. rusticl correctly sets the desired float
controls, we just have to match to the hardware requirements.

f06809cdca panfrost: Evict the BO cache when allocation fails
If memory allocation fails, we look for a suitable sized BO in the BO cache and
wait until we can use its memory. That usually works, but there's a case when it
can fail despite sufficient memory in the system: BOs in the BO cache
contributing to memory pressure but none of them being of sufficient size. This
case is not just theoretical: it's seen in the OpenCL
test_non_uniform_work_group, which puts the system under considerable memory
pressure with an unusual allocation pattern.

To handle this case, try evicting *everything* from the BO cache and stalling
in order to allocate, if the above attempts failed. Fixes the following error:

   DRM_IOCTL_PANFROST_CREATE_BO failed: No space left on device

on the aforementioned OpenCL test.

d849d9779a panfrost: Avoid blend shader when not blending
On Midgard, we need a "blend" shader even if blending is disabled, if the format
isn't blendable. This is inefficient. Bifrost solves this by decoupling the
format conversion from the blending, allowing opaque (unblended) output to any
format without a blend shader or fragment key.

Unfortunately, our blend code is from the Midgard era -- I wrote an early
version of nir_lower_blend when I was still in high school! -- so we've been
using blend shaders for opaque output even on Bifrost. Whoops!

In SuperTuxKart, reduces blend shader calls by 30%, translating to a 15%
reduction in i-cache misses.

Valhall, the register format for a BLEND comes from the instruction -- the
register format specified in the conversion descriptor (used on Bifrost) is
ignored. That means it has to match.

Previously, we always used a blend shader for integer rendering. Since blend
shaders ignore the register format of the BLEND instruction, that masked this
issue. That also means we don't need to backport this.

3298ac4b12 pan/decode: Remove pandecode_msg
It hasn't had a consistent semantic meaning since we've switched decoding over
to GenXML.

c4c3f246fe pan/decode: Don't pass around memory handles
The hardware doesn't care what BO a given buffer resides in, only what GPU
address it's at. It's simpler to fetch from a GPU address, rather than the pair
of a GPU address and a backing allocation. This cleans up a lot of cruft in
pandecode.

a8dbf61b46 panfrost: Add a debug option for checking overflows on pool uploads
PAN_MESA_DEBUG=overflow will place objects as close as possible to a
protected region at the end of the buffer, so that overflows segfault.

Caught the bugs in all four of the preceding commits.

v2: memset the BO to 0xbb to catch code expecting zeroed allocations.

379ae6d823 panfrost: Emit the correct number of attributes
create_vertex_elements_state is sometimes called with a too large
num_elements argument, for example with util_blitter, which causes a
buffer overflow.

There is no documentation to forbid this practice, so don't rely on
so->num_elements being correct and instead use the vertex shader
attribute count, which matches the value used to allocate the
descriptors.

Use attributes_read_count rather than attribute_count because the
latter also includes images and PAN_VERTEX_ID/PAN_INSTANCE_ID.

3a0a8688d3 panfrost: Use early-ZS helpers
Remove the previous compile-time early-ZS implementation and replace it with the
decoupled early-ZS implementation. This uses more efficient settings in some
cases (depth/stencil tests always passes or do not write), and fixes the
settings used in another case (alpha-to-coverage enabled with an otherwise
early-ZS shader.)

fe875c0144 panfrost: Unit test early-ZS helpers
The new early-ZS helpers are pure functions, leaf nodes of the call graph, and
implemented with a different algorithm from the "oracle" table of correct values
for various combinations of states. Further, incorrect settings often still pass
CTS while causing game bugs or inefficiencies. That combination makes the
helpers an excellent candidate for unit tests. Add some.
