zink: fix line-smooth interpolation

Extending the lines by half a pixel in each direction without doing
anything about the varyings makes the varyings interpolate over a
distance than intended. While this can be negligeble for long lines,
it can lead to big error for short lines.

Let's instead add extra geometry for each of the line-caps, so we can
make sure the varyings stay constant for the whole cap, and interpolate
over the intended distance instead.

zink: lower smooth-lines if not supported

This implements line-smoothing the same way as the draw-module does,
except using a geometry shader instead of a CPU pass.

Ideally, this should be enabled either by checking for the various
smooth-line caps, or by a DRIconf setting.

Unfortunately, RADV doesn't support he smooth-lines features, and we
don't want to force it down a pessimistic shader-key code-path. So that
plan is out the window for now.

While DRIconf is also neat, it's a bit of work to wire up, and we don't
really know of any real-world applications who would need this yet. So,
for now, let's just unconditionally enable is on the IMG proprietary
driver, which is going to need this for sure.

anv: Use vma_heap for descriptor pool host allocation

Pre-patch, anv_descriptor_pool used a free list for host allocations
that never merged adjacent free blocks.  If the pool only allocated
fixed-sized blocks, then this would not be a problem. But the pool
allocations are variable-sized, and this caused over half of the pool's
memory to be consumed by unusable free blocks in some workloads, causing
unnecessary memory footprint.

Replacing the free list with util_vma_heap, which does merge adjacent
free blocks, fixes the memory explosion in the target workload.

Disdavantges of util_vma_heap compared to the free list:
  - The heap calls malloc() when a new hole is created.
  - The heap calls free() when a hole disappears or is merged with an
    adjacent hole.
  - The Vulkan spec expects descriptor set creation/destruction to be
    thread-local lockless in the common case. For workloads that
    create/destroy with high frequency, malloc/free may cause overhead.
    Profiling is needed.

Tested with a ChromeOS internal TensorFlow benchmark, provided by
package 'tensorflow', running with its OpenCL backend on clvk.

iris: Don't reject CPU access for non-invalidating buffer write maps

Buffer maps that don't invalidate their destination range work better
as direct CPU maps than staging blits.  The application may write only
part of the range, effectively combining the new data with existing
data.  So even if the map would stall, the staging blit path won't help
us, as we have to read the existing data to populate the staging buffer
before returning it.  This incurs a stall anyway - plus a read and copy.

In contrast, a direct map doesn't need to read any data - it can just
write the destination and the existing data will still be there.

Fixes excessive blits for stalling buffer writes that don't invalidate
the buffer since my recent map heuristic rework.

st/mesa: Enable Alpha writes when writing RGB faked as RGBA

Some GPUs are able to render more efficiently when all channels of a
color attachment are written, since whole pixels are being overwritten,
rather than hitting a read-modify-write cycle where newly written data
has to be combined with existing unmodified image data.

When faking GL_RGB as RGBA (in case RGB/RGBX isn't color renderable),
we introduce an extra channel that doesn't exist from the application
point of view.  With such a format, a color mask of 0x7 (RGB) would mean
to write all channels.  But because we've added an alpha channel behind
their back, this becomes a partial write.  We are free to write whatever
garbage we want to the alpha channel, however.  So we can enable alpha
writes, making this a more efficient full pixel write again.

This is done unconditionally as it's expected to address a problem
common to many drivers and isn't expected to be harmful, even on GPUs
where it may not help much.

panfrost: Add tool to print supported texture formats

While all Panfrost-supported Mali GPUs support all the compressed texture
formats architecturally, the system integrator decides which formats will
actually be wired up in the production system-on-chip. In the past there may
have been legal considerations, I'm neither a lawyer nor a system integrator so
couldn't say.

It's useful for users to know which compressed texture formats are supported by
their hardware, to understand its performance characteristics (and perhaps to
buy systems that support their needs, especially if they need BCn formats which
are omitted in many Mali implementations).

To help with that, this commit adds a small standalone tool that prints which
formats are supported. It is tested so far on Mali-T860 and Mali-G57.

nir: Allow more than just ALU instructions in 'weak' GVN

This removes the ALU-only restriction on the "weak" GVN introduced by
the previous commit.  This makes it slightly more aggressive, allowing
it to coalesce things like UBO loads (still within sister then/else
blocks).  This also can have surprisingly large cascading effects.

I was concerned that this might increase register pressure, but

so it seems to be fine.

nir: Perform 'weak' global value numbering in all GCM passes

Full global value numbering (GVN) can be pretty aggressive, moving
values far away from their original locations, even out of loops,
and can extend their live ranges a lot.  So we've left it disabled.

This patch introduces a weaker form of GVN: we only allow coalescing
identical values when they appear on either side of the same if/else
construct.  For now, we also only allow ALU instructions.

This allows nir_opt_gcm to clean up identical instructions appearing
on both sides of if/then/else control flow.  But it avoids aggressively
combining every other occurrence of a value in the program.

This can still have surprisingly large cascading effects, as simple
constructs are cleaned up, leading to more opportunities to do the
same clean up, up a chain of nested ifs.  It also enables greater use
of the select peephole as ifs are cleaned up.

shader-db and fossil-db results show a reduction in spills/fills on
Icelake, so it doesn't seem to be hurting register pressure.

anv: remove anv_reloc_list->num_relocs

There are only a few places in the code where num_relocs gets set:

  - During anv_reloc_list_init() where it gets memset() to 0.
  - At anv_reloc_list_init_clone() where it gets set with the value of
    another anv_reloc_list->num_relocs.
  - During anv_reloc_list_clear(), where it gets set to 0.
  - During anv_reloc_list_append(), where it gets added with the value
    of another anv_reloc_list->num_relocs.

As you can see, either we explicitly set the value to 0 or we copy the
value that's present in another anv_reloc_list, which should be 0. The
one place where we used to increment num_relocs was in
anv_reloc_list_add(), but that was deleted by:

  7b7381e8d7a5 ("anv: Delete anv_reloc_list_add()")

So in this commit we delete the num_relocs field from struct
anv_reloc_list and we also delete some lines where, if the value is 0,
nothing will happen.

There's more we could be deleting here, but I wanted this commit to be
minimal so it's very clear that num_relocs can't be non-zero. We were
having some speculation that anv_reloc_list may still be important for
actually adding BOs to the batch and building the validation list, so
let's go slowly with the removal to make everything more easily
reviewable.

The one possibility I could be missing here is another situation like
the memset() we have at anv_reloc_list_init() or some other crazy
indirect overwrite, but as far as I have checked, that is not the
case.

wsi/x11: Fix possible deadlock with wait_ready.

With the introduction of locks around the XCB polling mechanism,
a possible deadlock was introduced.

If all 5 images were rapidly acquired and presented before the
FIFO thread had the chance to submit a present,
we would deadlock.

Before the lock however, it was still buggy since the two threads would
race to poll events and update internal state.

The fix is to just ensure that there are pending presentation requests
in flight, so that forward progress is guaranteed before we take the
poll lock.

Also, use a timedlock for acquire next image.

Similar as WaitForPresentKHR.
Also need to make the busy flag atomic to actually allow acquire thread
and present threads to access the busy flag.
Take advantage of busy flag being atomic so that we can gracefully handle

iris: Allow fast clears on compressed image load/store access

While I haven't found documentation saying definitively that HDC
supports fast clear blocks, it seems to work just fine, even on
Tigerlake.  I have found several issues (atomics and HDC support
for linear compression) that both call out fast clears as an issue
in those corner cases, which suggests that fast clears do actually
work outside of those corners (which we already disable).

The previous commit implemented actual aux state updates for image
views.  With ISL_AUX_USAGE_GFX12_CCS_E, this means that we update
the aux state to COMPRESSED_CLEAR after writes.  But because we
weren't supporting fast clears, this meant that any such images
would need partial resolves to remove the clear color on next use.
Supporting fast clears allows us to drop all these resolves.

already enabled for an image, we'd leave it disabled.  And, we avoided
writing via the CPU to buffers with auxiliary.  So in most cases, CCS
remained disabled, or got enabled (say by glTexImage()) then stayed on
permanently.  There were still issues, but they managed to remain more
hidden than one would expect given the severity of the bug.

iris: Drop disable_rb_aux_buffer handling for image views

The goal here is to support OpenGL 4.6 section 9.3, "Feedback Loops
Between Textures and the Framebuffer" (from GL_ARB_texture_barrier)
where you can bind an image as both a framebuffer attachment and a
texture, and simultaneously sample-from and render-to it.

I'm not aware of any spec language that requires us to handle
simultaneously accessing something as a framebuffer attachment and an
image load/store resource.  GL_ARB_shader_image_load_store tends to
make flushing and synchronization something the app has to handle
explicitly rather than something the driver needs to do implicitly.

iris: Drop 'isl_' prefix from 'formats_are_fast_clear_compatible'

Every time I see this function I think it's part of isl.  But it's not,
it's just a static function in an iris file.  The point of the name was
that the function checks two isl_format enums...but the prefix is just
confusing.  Just drop the prefix as it's a static function.

iris: Pin the clear color BO in use_image()

Images with the RC_CCS modifier store the clear color in a separate BO,
which we also need to pin when using an image view.

Most images store the clear color in the same BO so it works anyway.

Thanks to Nanley Chery for catching this!

iris: Drop batch parameter from iris_update_postdraw_resolve_tracking

Eventually the resolve code started making everything take ice instead
of batch, and at some point this ceased to be used.  It's always render.

radv/ci: bump most jobs to the kernel to 6.1 + latest firmwares

Unfortunately, not all jobs can be using Linux 6.1 right now, as
NAVI10 hits __vm_enough_memory errors then hangs in VKCTS. So for
this job, we will keep Linux 5.17 until this gets fixed.
