On newer devices where ZPASS_DONE events have sample count writing
abilities the firmware expects these events to come in begin-end pairs,
essentially corresponding to a typical occlusion query usage. Since this
event is also used in the autotuner we have to avoid event pairs to be
emitted in an interleaved fashion.
Additional renderpass state now tracks whether a given renderpass contains
an occlusion query. If so, autotuner will emit miscellaneous ZPASS_DONE
events in order to form its own begin-end pairs before and after the
renderpass commands.
Occlusion query behavior inside a renderpass doesn't change. But when used
outside of a renderpass, possible autotuner usage requires to again emit
ZPASS_DONE events that end up forming begin-end pairs of these events both
at the start and the end of the query.
