GL spec states that the stride for indirect multidraws:
* cannot be negative
* can be zero
* must be a multiple of 4
some drivers can't support strides which are not a multiple of the
size of the indirect struct being used, however, so rewrite those to
direct draws

Document how to build and use Panfrost's drm-shim implementation. I hope by
documenting this process, other Mesa developers are better able to test
Panfrost. In particular, this allows developers without Mali hardware to run
shader-db for any Mali target, which may be useful for debugging regressions
from common NIR changes.
drm-shim is not a substitute for testing against real hardware.
Special thanks to Emma Anholt and Icecream95 for building this infrastructure.

The optimized routine documented the tiling format together with the software
algorithm. The reference implementation wants the tiling format alone
documented. Let's break out the high level documentation into somewhere
centrally accessible, and refocus the comments in the optimized file on the
optimization.
This documentation is linked bidirectionally with both implementations, so it
should be easy to find.

Similar to pipeline statistics but done for a single counter.
We use REG_A6XX_RBBM_PRIMCTR_7 to get generated primitives
and not PRIMCTR_8 because PRIMCTR_7 counts pre-clipped prims
while PRIMCTR_8 counts them after clipping.
OpenGL spec for GL_PRIMITIVES_GENERATED says:
"Subsequent rendering will increment the counter once for every
vertex that is emitted from the geometry shader, or from the
vertex shader if no geometry shader is present."

Inline uniform blocks store their contents in pool memory rather
than a separate buffer, and are intended to provide a way in which
some platforms may provide more efficient access to the uniform
data, similar to push constants but with more flexible size
constraints.
We implement these in a similar way as push constants: for constant
access we copy the data in the uniform stream (using the new
QUNIFORM_UNIFORM_UBO_*) enums to identify the inline buffer from
which we need to copy and for indirect access we fallback to
regular UBO access.
Because at NIR level there is no distinction between inline and
regular UBOs and the compiler isn't aware of Vulkan descriptor
sets, we use the UBO index on UBO load intrinsics to identify
inline UBOs, just like we do for push constants. Particularly,
we reserve indices 1..MAX_INLINE_UNIFORM_BUFFERS for this,
however, unlike push constants, inline buffers are accessed
through descriptor sets, and therefore we need to make sure
they are located in the first slots of the UBO descriptor map.
This means we store them in the first MAX_INLINE_UNIFORM_BUFFERS
slots of the map, with regular UBOs always coming after these
slots.

When CCS compression first came out on Skylake, we referred to it as
"renderbuffer compression", or RBC for short. However, that name has
long since fallen out of favor, and we refer to it as CCS nearly
everywhere.
This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase
for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc
name continues to work, because it's one line of code and having both
names makes our lives easier in the interim.

This has been implemented for a while but we could not expose it on
Vulkan 1.0 because the extension declares a dependency on
VK_KHR_sampler_ycbcr_conversion, which we don't implement, and
CTS would complain.
On Vulkan 1.1 however, VK_KHR_sampler_ycbcr_conversion was promoted
to core as an optional feature, and this is enough for the the
dependency to be satisfied, even if the feature is not supported,
meaning that we can now expose the extension.
