2cfc7776bd nir: Handle wildcards with casts in copy_prop_vars
If we're propagating a copy from a cast where the copy copies an entire
array, we end up with something like &((S *)ssa_N)->f[*] in the source
where a wildcard has a cast in its parent chain.  If we then try to
propagate the read into a non-wildcard array load, we have to specialize
the wildcard.  This breaks because nir_build_deref_follower() doesn't
handle casts.  Since we know a priori that, because wildcards are only
generated by copy_deref on arrays, we cannot have a cast with a wildcard
parent so simply chasing the source deref to the first wildcard will
ensure that any casts in the deref are handled properly.

5443e66190 rusticl: Show an error message if the version of bindgen can't be detected
bindgen 0.69.0 broke the `--version` switch, resulting in misleading errors about requiring at

69e6b0307b venus: switch to unconditionally deferred query feedback
All commands that make queries available have feedback cmds batched
and stored during recording. At submission time, for each batch
(SubmitInfo) these feedback cmds are recorded in a cmd buffer that is
appended after the last original cmd buffer (but before
semaphore/fence feedback).

Query reset cmds are deferred as well and also remove any prior feedback
cmds for queries its resetting within the batch.

ldunifa works exactly the same as ldunif: the hw will prefetch the
next 4 bytes after a read, so if a buffer is exactly a multiple of
a page size and a shader uses ldunifa to read exactly the last 4 bytes
the prefetch will read out of bounds and spam the error on the kernel
log. Avoid that by allocating extra bytes in this scenario.

423202cae4 rusticl/queue: Only take a weak ref to the last Event
This resolves a memory leak when the application drops its last reference
to the queue, but never waits explicitly.

The problem was, that the queue was refed by QueueState::last and that ref
only gets dropped on a blocking wait. This is problematic as non user
Event objects also hold a ref on the Queue they are created on, therefore
causing a cyclic ref relation.

In order to resolve it, just use a weak reference. A failure of upgrading
the Weak ref is not an issue as in this case we'd only wait on an already
destroyed or processed event. The worker thread already makes sure
everything stays in sync.
