Does this fix anything known?
I am writing CTS tests for VK_EXT_host_query_reset extension and I
found this bug while testing them on RADV.
Does that rule also apply for CmdCopyQueryPoolResults()? If so, we
might
need to fix it (I haven't looked yet).
The rule is slightly different on CmdCopyQueryPoolResults():
"Similarly, if VK_QUERY_RESULT_WITH_AVAILABILITY_BIT is set and
VK_QUERY_RESULT_WAIT_BIT is not set, the availability is guaranteed to
reflect the most recent use of the query on the same queue, assuming
that the query is not being simultaneously used by other queues. As
with vkGetQueryPoolResults, implementations must guarantee that if they
return a non-zero availability value, then the numerical results are
valid."
So if VK_QUERY_RESULT_WITH_AVAILABILITY_BIT we need to still set the
availability state.
I skimmed the implementation of this function on RADV, it seems it is
missing setting the availability value for all the queries except for
VK_QUERY_TYPE_TIMESTAMP.
Could you take care of this?
Yes, do you have tests for CmdCopyQueryPoolResults()?
With the comment on patch 1, series is:

OK, thanks! It seems I did a wrong squash of patches on patch 1. I will
fix it and push both patches to master.

status field for each query.
From Vulkan spec:
"If VK_QUERY_RESULT_WAIT_BIT and VK_QUERY_RESULT_PARTIAL_BIT are
both
not set then no result values are written to pData for queries that
are
in the unavailable state at the time of the call, and
vkGetQueryPoolResults returns VK_NOT_READY. However, availability
state
is still written to pData for those queries if
VK_QUERY_RESULT_WITH_AVAILABILITY_BIT is set."
