On GFX10+, the hardware can write decompressed DWORDS to HTILE when
COMPRESSION_EN=1, which means some HTILE decompression/initialization
operations can be avoided because it automatically mark the tiles that
are touched as uncompressed.
Though according to PAL, there are issues with that on GFX10-10.3, so
it's only enabled on GFX11-11.5.

Only for partial copies because image stores don't decompress on writes
(ie. HTILE isn't updated by image stores).

The driver either does a fast-clear using compute or a slow clear
using graphics, so the "fast" clear using graphics isn't used at all.

Right after "normal" layout transitions and just before the rendering
state is set, mostly because it doesn't need to be saved/restored
either.

In glibc 2.43 the strstr function now propagate const to the output, triggering -Wincompatible-pointer-types-discards-qualifiers
under clang/gcc with -Werror.
Fix two of these cases by adding the const qualifier.

This could return the graphics DCC pipeline if it was created before,
and crash or potentially hang the GPU.
Found this while working on in-progress VKCTS coverage.

This was an oversight of VK_KHR_dynamic_rendering_local_read which has
been addressed by VK_KHR_maintenance10 which introduced new flags to
give more information to implementations.
The Vulkan spec says:
"VK_RENDERING_ATTACHMENT_INPUT_ATTACHMENT_FEEDBACK_BIT_KHR is
intended to give implementations similar information as a subpass
where an attachment could be used as both a color attachment and
input attachment. Some implementations require extra work to make
this scenario work beyond just considering the image layouts.
Implementations which have no such considerations may treat this
flag as a noop. The primary use case for this flag is to enable
feedback loops inside a single shader."
"Applications are encouraged to use
VK_RENDERING_LOCAL_READ_CONCURRENT_ACCESS_CONTROL_BIT_KHR if
maintenance10 is available and they use feedback loops with
VK_KHR_dynamic_rendering_local_read. Feedback loops are still
allowed when not using the rendering flag, but the performance
implication was an oversight in the original definition of
VK_KHR_dynamic_rendering_local_read."
Because it's clearly defined by the Vulkan spec, let's just pessimize
always to avoid relying on some shaders state which require to do very
late decompression passes. This will allow us to do more cleanups and
optimizations related to the framebuffer. Also note that DRLR is still
a niche feature.

If the rendering state is inherited in the secondary, otherwise nothing
wait for the pending flushes after a decompression pass. One more
argument to stop delaying this.

Avoiding NaNs should have the same effect but it's good practice to not
rely on float OPs for correctness.

It was incorrect to mark chit/miss arguments as discardable without
the equivalent in the traversal shader. Also, tail calls with modified
parameters that aren't marked discardable are incorrect.
This could lead to random corruption by clobbering parameter values
across two levels of nested calls: A Raygen shader calls traversal,
expecting e.g. the ray tMax parameter to be preserved. Traversal
overwrites the parameter's register with the hit t and tail-calls chit,
which immediately returns to raygen. Now the raygen shader still has the
clobbered tMax (which is actually the ray hit t) - if it calls traversal
multiple times, the second traversal iteration may use the previous
ray's hit t as tMax instead of the intended value.
