If we have NIR such as:
32x4 %48 = @load_vulkan_descriptor (%47) (desc_type=SSBO)
32x4 %76 = deref_cast (tint_symbol_11 *)%48 (ssbo tint_symbol_11) (ptr_stride=0, align_mul=4, align_offset=0)
32x4 %77 = deref_struct &%76->tint_symbol_10 (ssbo int) // &((tint_symbol_11 *)%48)->tint_symbol_10
A single nir_rematerialize_deref_in_use_blocks() will rematerialize the
deref_struct and then it's deref_cast. However,
nir_foreach_instr_reverse_safe is not safe if the next iteration's
instruction is removed. This can result in the instruction loop exiting
and the load_vulkan_descriptor never having an LCSSA phi.

The game aliases two images. It binds a memory object to two different

only one mip but the bind offset is incorrect. It's like it queried

disabled.
Force disabling DCC for mips fixes the incorrect rendering and doesn't

In two functions implementing resource discard rebind_resource is called
on resource before its track record is reset. This prevents update of
dirty_resource or dirty_shader_resource because of conditions in
needs_dirty_resource. With rsc->track reset and dirty_resource bits
missing further calls to transfer_map will not try to reallocate
resource storage when needed.
A way to reproduce the issue in both functions is by executing at least
3 draws modifying bound texture or VBO each time. This patch fixes those
cases and some related piglit tests on a5xx and should fix it on other
GPUs. Also it fixes rendering in Firefox and vsraytrace (except vertical
line at right edge).

This fixes a corner case of the LNL sub-dword integer restrictions
that wasn't being detected by has_subdword_integer_region_restriction(),
specifically:
> if(Src.Type==Byte && Dst.Type==Byte && Dst.Stride==1 && W!=2) {
> // ...
> if(Src.Stride == 2) && (Src.UniformStride) && (Dst.SubReg%32 == Src.SubReg/2 ) { Allowed }
> // ...
> }
All the other restrictions that require agreement between the SubReg
number of source and destination only affect sources with a stride
greater than a dword, which is why
has_subdword_integer_region_restriction() was returning false except
when "byte_stride(srcs[i]) >= 4" evaluated to true, but as implied by
the pseudocode above, in the particular case of a packed byte
destination, the restriction applies for source strides as narrow as
2B.
The form of the equation that relates the subreg numbers is consistent
with the existing calculations in brw_fs_lower_regioning (see
required_src_byte_offset()), we just need to enable lowering for this
corner case, and change lower_dst_region() to call lower_instruction()
recursively, since some of the cases where we break this restriction
are copy instructions introduced by brw_fs_lower_regioning() itself
trying to lower other instructions with byte destinations.
This fixes some Vulkan CTS test-cases that were hitting these
restrictions with byte data types.

We were accidentally doing a signed integer comparison here for ult32,
or a sign-extending shift for ushr.
One notable bit of fallout was that load_global_uniform_block_intel
address calculations broke on platforms that don't have native 64-bit
integer support, as the iadd64 lowering for "do I need to carry?" was
using ult32...and performing the wrong comparison. We spotted this in
Borderlands 3 on Alchemist once we turned on other optimizations.

The BROADCOM_SAND128 modifier is usually used with an extra parameter
to pass in the stride via a side channel. Quoting from drm_fourcc.h:
> The pitch between the start of each column is set to optimally
> switch between SDRAM banks. This is passed as the number of lines
> of column width in the modifier (we can't use the stride value due
> to various core checks that look at it , so you should set the
> stride to width*cpp).
So apparently this is just a workaround for limitations in some kernel
APIs. DRM modifiers, however, are arguably a bad fit for extra
parameters that aren't known in advance. In the Wayland/KMS ecosystem
many components depend on being able to treat modifiers as opaque, e.g.
for negotiations etc. In practice the current approach requires various
software components to manually use the
`DRM_FORMAT_MOD_BROADCOM_SAND128_COL_HEIGHT()` macro - using the
`DRM_FORMAT_MOD_BROADCOM_SAND128` modifier directly with formats like
`NV12` results in a rejection in the KMS driver and corrupted output
in Mesa (because we'd bail out early in `v3d_sand8_blit()`).
Fortunately the stride check limitations mentioned above don't seem to
apply to Mesa though. Thus we can just add support for the base modifier
and stride (coming from V4L2), allowing various toolkits, Wayland
compositors and V4L2 decoder implementations to support e.g.
`NV12` + `DRM_FORMAT_MOD_BROADCOM_SAND128` (`NC12` in V4L2) in a generic
way.
Notes:
1. Wayland compositors trying to offload composition to KMS will still
fail when doing a test commit.
2. There is another limitation - in the V4L2 MPLANE API - that
requires userspace to know the correct offset of the second plane. That's
a known API limitation though and only affects V4L2 decoder implementations.

Since the shader parameters are passed as inline data, push constants
are no longer used and so, not actually set on dispatch. But the
nr_params = 4 was still making the shader emit the code to load them,
causing page faults on simulation, and would also on HW if we didn't
always have a scratch page set.
The uses_inline_data parameter will be set from brw_compile_cs(), called
shortly after this point, so we don't need it here.
The subgroup_size is misleading, as we don't actually require that size
and the code that checks for it isn't even running for this shader.

pipelines to run despite the KernelCI, during the CI meeting with @sergi
and @mupuf it was determined that the Mesa releases are an important
enough operation to warrant being a higher priority than user forks
