e145579956 rusticl: fix flag validation when creating an image
From the OpenCL specification:
    `CL_MEM_KERNEL_READ_AND_WRITE`: This flag is only used by
    clGetSupportedImageFormats to query image formats that may be both
    read from and written to by the same kernel instance. To create a
    memory object that may be read from and written to use
    CL_MEM_READ_WRITE.

If an application follows the instructions above, i.e. query a list of
supported image formats, using `CL_MEM_KERNEL_READ_AND_WRITE` as
input, and then attempts to create an image using one of the supported
image formats, by calling `clCreateImage` and passing
`CL_MEM_READ_WRITE`, the call to the image creation entry point should
succeed. This instead fails on Mali devices with the error
`CL_IMAGE_FORMAT_NOT_SUPPORTED`.

Rusticl fails when validating the image format against its supported
flags. Formats that support `PIPE_BIND_SHADER_IMAGE` have their
supported flags set as `CL_MEM_WRITE_ONLY` and
`CL_MEM_KERNEL_READ_AND_WRITE`.

This changes the supported CL flags to be `CL_MEM_WRITE_ONLY` for
`PIPE_BIND_SHADER_IMAGE` and `CL_MEM_READ_WRTE |
CL_MEM_KERNEL_READ_AND_WRITE` for `PIPE_BIND_SAMPLER_VIEW |
PIPE_BIND_SHADER_IMAGE`.

Fixes: 3386e142 (rusticl: support read_write images)

Fixes OpenCL-CTS test: `test_image_streams` on Mali. Invocation:
```
test_image_streams write 1D CL_RGB CL_SIGNED_INT8
```

ec101645ff vc4: fix unwanted buffer release on uploader
Some checks failed
macOS-CI / macOS-CI (dri) (push) Has been cancelled
macOS-CI / macOS-CI (xlib) (push) Has been cancelled
When converting the index buffer from 4-bytes to 2-bytes, we use the
uploader for the job. Since commit b3133e250e we do an uploader alloc
ref, which releases the uploader buffer if there is no enough space,
creating a new one.

The problem happens when we also need this buffer because it is the one
containing the index buffer to convert. This happens, for instance, if
we need to convert the primitives because they are not supported (e.g.,
converting quads to triangles), as this is done
also using the uploader.

The solution is to ensure the uploader's buffer has an extra reference
so when released, it is not destroyed. This can easily achieved by
calling first pipe_buffer_map_range(), which is required to access the
buffer, and it increases the references.

This fixes `spec@!opengl 1.1@longprim`.

dfd0e55b5a r300: split large HiZ clears into multiple packets
R300_PACKET3_3D_CLEAR_HIZ encodes COUNT in 14 bits (COUNT[13:0]), so a
single packet can clear at most 0x3fff dwords.

Large depth surfaces on R5xx can require more HiZ dwords than that.
When we emitted a single packet, COUNT truncated and part of HiZ RAM
remained uncleared, which could show up as HyperZ corruption.

Emit CLEAR_HIZ in chunks of R300_CLEAR_HIZ_COUNT_MAX and reserve enough
atom space for the worst-case packet count derived.

af53a9bfbc dri: Fix "cosmetic" undefined behaviour warning for RGB[A]16_UNORM formats.
Ian Romanick reported some "undefined behaviour" warnings during some
not specified tests, relating to introduction of RGB[A}16_UNORM formats
in merge request
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/38588

This due to overflowing the 32-bits masks[], and then during assignment
the red/green/blue/alphaMask fields in struct gl_config when using a 16
bpc format. Iow. the red/green/blue/alphaMask would not be usable.

Suppress this warning by setting masks[] to zero for unorm16 formats,
just as was previously done for is_float16, ie. fp16 formats.

16 bpc formats are only exposed for display on non-X11 WSI target
platforms like GBM+DRM, Wayland, surfaceless, and these platforms do
not use the info in red/green/blue/alphaMask at all, so the "undefined
behaviour" is meaningless.

58ab5760c1 panfrost: Fix NULL pointer dereference in panfrost_emit_images
Fix a crash in image descriptor emission caused by stale image_mask bits.

Root cause:
- set_shader_images used a shift expression with count==64 when clearing
  image_mask, which is undefined behavior in C.
- This could leave image_mask inconsistent with actual image bindings,
  so panfrost_emit_images() might dereferences NULL image resources.

Fixes:
- Use 64-bit-safe bit helpers for mask updates to avoid invalid shifts.

Crash observed when running: OpenCL-CTS api/test_api

99129b13ce iris: fix a crash in disable_rb_aux_buffer
I have been running into crashes in this function when using blender.
Some of the entries in ice->state.framebuffer.base.cbufs[0] can
apparently have the texture field be null, which was causing a segfault
in this loop.

In my case, nr_cbufs was 3, and the first two cbufs entries had a null
texture and format set to PIPE_FORMAT_NONE. The last entry had format of
PIPE_FORMAT_R16G16_FLOAT and a non-null texture.

Adding this null check before attempting to dereference the texture
fixes the crash for me and allows blender to work normally.

dfa0f6706d gallium/u_blitter: add a new fs_color_clear variant
The referenced commit switched from a passthrough shader
to fs_clear_color[write_all_cbufs=0]. It shouldn't matter since
the shader isn't supposed to be executed - it's only setup to get
the first color output active.

On some chips (gfx8) it seems to cause issues (hangs or page fault)
for some piglit tests, eg:
  framebuffer-blit-levels draw stencil

To fix this, introduce a 3rd variant, where a constant buffer isn't
required and instead the color is hardcoded in the shader.

d5f9f12123 radeonsi: account for outputs_written when updating spi_shader_col_format
Variants can modify which outputs get written so we must update
these fields otherwise spi_shader_col_format will be incorrect.

This can happen for instance with uniforms inlining:

   uniform bool depth_only;
   void main() {
      if (depth_only) return;
      ...
   }

When depth_only is true, this shader becomes empty after uniforms
inlining but spi_shader_col_format wasn't updated properly,
causing a hang.

eccd9df749 llvmpipe: Stop aligning height to raster block size for unbacked handles
This code path is usually used by lavapipe when importing dmabufs, not
for output.
The resulting size_required is then used to calculate the size
requirements for VkMemoryRequirements2 etc. Requiring a multiple of
LP_RASTER_BLOCK_SIZE - 4 - can eventually result in lavapipe rejecting
dmabuf imports.

An example is YUV420 at a resolution of 1680x1050 produced by Gstreamer
1.28 - e.g. from a screencasts. In this case we currently compute a size
of 3235840, while other drivers like radv compute 3225600. The actual
size is 3227648, fitting into the later but not the former.

Removing the alignment brings lavapipe in line with other drivers.

eea697b179 r300: disable clip-discard watermark for triangles
Commit 0d4aa5f55f introduced the watermark to optimize the guardband
state changes and always computed new_distance as MAX2(distance,
watermark).

That is correct for point/line paths where distance > 0, but it keeps a
non-zero discard distance alive when the next draw sets distance = 0
(triangles). This leaks wide point/line clip-discard state into later
triangle draws and can clip away large parts of geometry (as observed in
Sauerbraten). Only apply the watermark when distance > 0 and reset it to
zero otherwise so triangle draws disable clip-discard as intended.

31ea1923de v3d: reject fast TLB blit when RT formats don't match
v3d_tlb_blit_fast includes the blit onto a pending job that writes
to the source resource. The TLB data is already unpacked according to
the job's RT format, so storing it with a different RT format performs
a channel reinterpretation rather than a raw byte copy, corrupting the
data.

So when copying from RGB10_A2UI to RG16UI with glCopyImageSubData,
the copy_image path remaps both formats to R16G16_UNORM for a raw
32-bit copy. The fast TLB blit found the pending clear job
(RGB10_A2UI, 4 channels: 10-10-10-2) and stored its TLB data as RG16UI
(2 channels: 16-16), writing the unpacked 10-bit R and G channel values
into 16-bit fields instead of preserving the raw packed bits.

Previous internal_type/bpp check was insufficient: both RGB10_A2UI
and RG16UI share internal_type=16UI and the source bpp (64) exceeds
the destination bpp (32), but their channel layouts are different.

Add a check that the job's source surface RT format matches the blit
destination RT format before allowing the fast path.

allowed precision mismatches on uniforms, however if you lower precision on

So here we relax the type matching and just make sure we match int vs

02f422a145 r300: disable HiZ for PIPE_FUNC_ALWAYS
AMD docs support this:
R5xx Acceleration v1.5 says safest handling for ZFUNC changes is to disable
HiZ except specific LESS/LEQUAL and GREATER/GEQUAL transitions.
ATI OpenGL Programming and Optimization Guide advises avoiding ALWAYS when
trying to benefit from HiZ so that would imply fglrx also disables HiZ
there.

On RV530 this fixes the following dEQPs:
dEQP-GLES2.functional.fragment_ops.interaction.basic_shader.43
dEQP-GLES2.functional.fragment_ops.interaction.basic_shader.74

7d25d214f5 vc4: flush write jobs before BO replacement in DISCARD_WHOLE path
The DISCARD_WHOLE_RESOURCE path in vc4_map_usage_prep() replaces the
resource's BO with vc4_resource_bo_alloc(). As the RCL resolves
rsc->bo at job submit in vc4_submit_setup_rcl_surface(), any pending
write job would store to the new BO instead of the old one, corrupting
the new written data.

This is the same bug that was fixed in v3d in the previous commit.

This is adressed by flushing all pending write jobs affecting the

6f28830365 r600: fix cs atomic operations when the shader is called multiple times
This change is useful when the compute shader is called multiple
times with the atomic operations enabled. It fixes some data
coherency issues. This is done by moving
evergreen_emit_atomic_buffer_setup() after r600_flush_emit().

This change is also a partial fix for compute_shader.pipeline-compute-chain.
In this specific case, it makes the memory barrier working.

This change was tested on cayman and barts; it makes these tests
fully deterministic:
