Classes
class	GpuRegionTimerWrapper< GpuRegionTimerImpl >
	This is a GPU region timing wrapper class. It allows for host-side tracking of the accumulated execution timespans in GPU code (measuring kernel or transfers duration). It also partially tracks the correctness of the timer state transitions, as far as current implementation allows (see TODO in getLastRangeTime() for a disabled check). Internally it uses GpuRegionTimerImpl for measuring regions. More...

Variables
static const bool	c_debugTimerState = true
	Debug GPU timers in debug builds only.
