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.

Graphics Flight Recorder is:
"The Graphics Flight Recorder (GFR) is a Vulkan layer to help
trackdown and identify the cause of GPU hangs and crashes.
It works by instrumenting command buffers with completion tags."
This is a nice little tool which could help quickly identify the call
which hanged. Or if command buffer is executed for too long.
The tiling nature of our GPU shouldn't be a big issue aside from
lower performance.
For non-segfault case, if:
- Hang happens at the same place in cmdbuf and draw/dispatch is not
finished at that point - it is likely that there is an infinite
loop in some of the shaders in this draw.
- Hang happens always in different place - likely there is nothing
wrong and command buffer just takes too long to execute and you
should try increasing hangcheck_period_ms. If it doesn't help
it is likely a synchronization issue.
