7a65b3f006 v3dv: reimplement occlusion queries
Our implementation was mostly CPU-based, with things such as query
resets and result copying handled in the CPU, as well as some aspects
of query availability tracking.

This new implementation handles all GPU-side query functions by
dispatching compute shaders to push the work to the GPU. This
involves query availability, reset and result copying.

For now, only occlusion queries are managed this way. Performance
queries can also be implemented in a similar fashion in the future
with some additional work, however, for timestamp queries our only
option to improve this would be to execute the actual timestamp in the
kernel, since we can't take a timestamp from a shader.

cc9db4eac2 v3dv: reset pending cpu job state once processed
If we have any pending jobs queued in the command buffer state
to be emitted at the end of a given job, make sure we reset
that state once these have been processed.

There are 3 reported flakes over a period of a month, and we have been

1174f37609 broadcom/compiler: avoid using ldvary sequence to hide latency of branching
This can cause us to stomp the contents of r5 before we have a chance to read
it, like this:

0x3d103186bb800000 nop                           ; nop                         ; ldvary.r0
0x3d105686bbf40000 nop                           ; mov rf26, r5                ; ldvary.r1
0x020000ef0000d000 bu.allna  232, r:unif (0x0000001c / 0.000000)
0x3d1096c6bbf40000 nop                           ; mov rf27, r5                ; ldvary.r2

Here, the MOV in the last instruction is supposed to read r5 produced from
ldvary.r0, but because we have inserted the bu instruction in between now
that read happens at the same time that ldvary.r1 updates r5, stomping the
value we were supposed to read.

Fix this by disallowing injection of a branch instruction in between an ldvary
instruction and its write to the r5 register 2 instructions later.

29588fe116 v3dv: re-enable sync_fd import/export
Now that we implement GPU-side event functions in the GPU we
no longer have the issue that didn't allow us to expose
sync_fd.

Further more, new spec text has also made the problematic
behavior undefined, so the test that caused this issue,
dEQP-VK.api.external.semaphore.sync_fd.import_twice_temporary,
is incorrect and should be fixed.

It should be noted that we still keep sync_fd disabled in the
simulator, at least until the CTS tests are fixed, since the
synchronous execution model of the simulator means that in the
problematic scenario we can block the CPU on the execution
of the command buffer before we ever submit the signaling job,
still causing a deadlock.

returns a vec2, of which we want component 0 which holds the actual
index. Typically, this will be cleaned-up by the time we get to
emitting VIR so the index is a single scalar component, but there
are some cases where this might no be the case, so make sure we don't
assume it to be a scalar, like we do in other places.

07c7d846e5 v3dv: drop layout refs for all allocated sets from a pool on destroy / reset
In 7f6ecb8667 we added reference counting for descriptor set layouts,
however, we didn't realize that pools created without the flag
VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT don't free individual
descriptors and can only be reset or destroyed. Since we only drop
references when individual descriptor sets were destroyed, we would
leak set layouts referenced from descriptor sets allocated from these
pools.

Fix that by keeping a list of all allocated descriptor sets (no matter
whether VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT is present or
not) and then traversing the list dropping the references on pool resets
and destroys.

019529aa11 broadcom/compiler: call nir_opt_gcm with a custom strategy
nir_opt_gcm get us worse shader-db stats, but that is expected. But we
want to prevent to get worse values on spill/fills. Analyzing the
outcome with shader-db, this mostly happen with shaders that are
already complex, and are already spilling/filling.

So the best option here is adding a new strategy, that fall backs if
we get spill/fill using nir_opt_gcm.

It is not clear in which order we should disable gcm. For now we
disable it before loop unrolling.

We get a slight performance gain (in average) using nir_opt_gcm.

We don't show the shaderdb stats, as they are worse, but as mentioned,
this is expected.

afc6de356a broadcom/compiler: pass a strategy struct to vir_compile_init
That allows to reduce the number of parameters of the method. And
after all, they were already filled using an existing strategy struct.

This would make easier adding new fields on a strategy.
