Subject: radv: sync before resetting a pool if there is active pending queries
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=eaeaad25f78a3a6676518f54cc4d30945efd3a59;p=mesa.git

radv: sync before resetting a pool if there is active pending queries

Make sure to sync all previous work if the given command buffer
has pending active queries. Otherwise the GPU might write queries
data after the reset operation.

This fixes a bunch of new dEQP-VK.query_pool.* CTS failures.
