Function decideTimingMode

decideTimingMode(request: TimingModeRequest): TimingMode
Decides which timing mode to run in. Pure decision table:

enabled hasTimestampQueryFeature allowCpuFallback → mode

false * * disabled

true true * gpu-queries

true false true (default) cpu-fallback

true false false disabled

Never throws: an absent feature degrades to a labelled fallback (or to disabled), it never crashes the caller for asking.
Parameters
- request: TimingModeRequest
Returns TimingMode
