1a0e7d18a2 pan/kmod,panvk: use uint64_t and not size_t for device sizes
When the host process is 32-bit, size_t can not express all of the
device address space. Note that there's still a lot of code that
uses size_t for device sizes remaining. Cleaning that up is left
for future MRs.

f9248e81a5 pan/lib: clean up tilebuffer size helpers
This way we report the *actual* tilebuffer sizes rather than reporting
twice the amount and then correcting for it later on. The distinction
really only matters on V4 and V6 GPUs, but let's get it correct.

This shouln't have any functional changes, it just makes it easier to
reason about what each GPU supports.

While we're at it, correct the typo in the comment about what gens
supports disabling pipelining. It's *not* supported on V6.

6a83193771 pan/lib: clamp format size to 4
When using formats with less than 32-bits per pixel, we pad the
tile-buffer to a multiple of 32-bits so we can store additional bits
used by dithering.

Account for this when computing the max MSAA setting.

a909e1e6ff pan/image: Provide two helpers to check image viability
pan_image_test_props() checks all the image properties at once, and
pan_image_test_modifier_with_format() just a <modifier,format> pair.

This will allow us to use the check done in pan_mod instead of
duplicating the same set of rules in panvk/panfrost and possibly having
one that's ahead of the other.

There are still checks we can't do at the pan_mod/image level, like
anything involving format lowering, but that's okay.

6ab7a03aef panfrost: Split texture lowering passes
We now have lower_texture_early and lower_texture.

lower_texture_early handle nir_lower_tex and (in the future) could handle
anything that is backend specific that need to happen before nir_lower_io.

lower_texture handles actual lowering of backend specific things that
must happen after nir_lower_tex and nir_lower_io.

This allows us to finally not run nir_lower_tex two times in panvk.

fed682c506 pan/lib: do not duplicate enum mali_pixel_kill
The enum pan_earlyzs is just enum mali_pixel_kill under a different
name, which was needed because the enum was missing from common.xml.

However, because pan_earlyzs_lut is used in files that are both included
with PAN_ARCH unset and set to values including values lower than 6, we
get issues with the way genxml/common_pack.h gets included, resulting in
the enum not being defined.

We don't really depend on the values for this, only on the size. So
let's just use unsigned values in the struct instead, to side-step the
issue.

0dcf510c05 pan: use translate_s_format for stencil
While this was also using translate_zs_format() before the commit in
question, that's didn't lead to any real issues, because only a single
value was legal here before. While it's not entirely in-spec to use
other values, it seems the HW doesn't mind.

But when this logic was reworked, the typed field was used instead. This
lead to a compiler warning on Clang.

Let's correct this properly here, rather than papering over the compiler
warning.

ddf2aa3a4d build: avoid redefining unreachable() which is standard in C23
In the C23 standard unreachable() is now a predefined function-like
macro in <stddef.h>

See https://android.googlesource.com/platform/bionic/+/HEAD/docs/c23.md#is-now-a-predefined-function_like-macro-in

And this causes build errors when building for C23:

-----------------------------------------------------------------------
In file included from ../src/util/log.h:30,
                 from ../src/util/log.c:30:
../src/util/macros.h:123:9: warning: "unreachable" redefined
  123 | #define unreachable(str)    \
      |         ^~~~~~~~~~~
In file included from ../src/util/macros.h:31:
/usr/lib/gcc/x86_64-linux-gnu/14/include/stddef.h:456:9: note: this is the location of the previous definition
  456 | #define unreachable() (__builtin_unreachable ())
      |         ^~~~~~~~~~~
-----------------------------------------------------------------------

So don't redefine it with the same name, but use the name UNREACHABLE()
to also signify it's a macro.

Using a different name also makes sense because the behavior of the
macro was extending the one of __builtin_unreachable() anyway, and it
also had a different signature, accepting one argument, compared to the
standard unreachable() with no arguments.

This change improves the chances of building mesa with the C23 standard,
which for instance is the default in recent AOSP versions.

All the instances of the macro, including the definition, were updated
with the following command line:

  git grep -l '[^_]unreachable(' -- "src/**" | sort | uniq | \
  while read file; \
  do \
    sed -e 's/\([^_]\)unreachable(/\1UNREACHABLE(/g' -i "$file"; \
  done && \
  sed -e 's/#undef unreachable/#undef UNREACHABLE/g' -i src/intel/isl/isl_aux_info.c

a9a3ee3719 panfrost: Get AFBC-P payload layout on the CPU
The AFBC-P payload layout is currently retrieved in 2 steps starting
with the payload sizes retrieval using a CS job on the GPU followed by
a CPU pass to set the payload offsets. This commit proposes to do both
steps on the CPU at once using a new utility function
pan_afbc_payload_layout_packed().

A new utility function pan_afbc_payload_uncompressed_size() is added
to help retrieve the uncompressed size from a pipe_format and
modifier. Both the CPU and GPU versions use it now.

A new AFBC-P driconf option "pan_afbcp_gpu_payload_sizes" is added to
fallback to the original payload sizes retrieval on the GPU.

RTs, we just define a layout per variant instead of overlays, which makes
dumps less verbose, and avoid the situation where overlapping fields
get accidentally overwritten in the desc emission logic.

While at it, add the `Surface stride hi` fiels to the ZS/Color target
descriptors so we're all set to bump the image size limit.

5fe1b95b33 pan: Make it so all pan_image_xxx helpers get passed an image
Some layout related helpers are being passed images subfields. Let's
make things consistent by always passing an image, plus extra parameters
to specify which part of the image is addressed.

While at it, move these helpers protypes/definitions to pan_image.h.

53e5e07c4b pan: Add the concept of modifier handler
There are a few operations that are modifier specific. Instead of
spreading the

   if (is_mod_x) do_x
   else if (is_mod_y) do_y
   ...

pattern, let's add the concept of mod handler so we can abstract away
these operations and get rid of some boiler-plate.

92ea3139c1 pan/layout: Don't mix AFBC and non-AFBC properties
AFBC is different from other modifiers (AFRC, u-tiled and linear) in that
metadata is placed in a separate memory section that needs to be properly
sized/aligned. This forces us to have header/body (or metadata/payload)
info stored at the layout level if we don't want to recalculate one
from the other everytime we need to fill descriptors.

Those properties were already present, but some of them were encoded in
non-afbc prefixed fields which makes things very confusing. Let's clarify
that by moving AFBC properties to their own struct, and move the
previously generic {row,surface}_stride_B to a tiled_or_linear struct.
We use a union to combine both.

With this sanitized semantics, we can fix some inconsistencies in our
AFBC layout initialization, hence the functional changes to
test-layout.cpp.

dad53edc9c pan/layout: Relax alignment constraints on pre-v7 for imports of linear/u-tiled
Commit f64a7c1506 ("pan/layout: Check the wsi_layout consistency in
wsi_row_pitch_to_row_stride()") introduced stricter alignments on pre-v7
for linear/tiled imports. It turns out alignment constraints on pre-v7 are
weaker than they are on v7+, and this got lost in the refactoring.

Let's fix linear_or_tiled_row_align_req() helper so we can import images
that don't have their base address/row_pitch aligned on a cacheline, and
only cacheline alignment for images we create ourselves.

Also add unittests to make sure we don't regress that in the future.
With this being tested, we can also use
pan_linear_or_tiled_row_align_req() in offset_align_for_mod()
(test-layout.cpp) instead of open-coding it.
