Detailed Description

Container class for queueing GpuCopyDesc instances in pinned (non-pageable) CPU memory.

Constructor & Destructor Documentation

pxtask::GpuCopyDescQueue::GpuCopyDescQueue ( GpuDispatcher & d ) [inline]

GpuCopyDescQueue constructor.

pxtask::GpuCopyDescQueue::~GpuCopyDescQueue ( ) [inline]

GpuCopyDescQueue destructor.

Member Function Documentation

void pxtask::GpuCopyDescQueue::enqueue ( GpuCopyDesc & desc ) [inline]

Enqueue the specified copy descriptor, or launch immediately if no room is available.

References pxtask::GpuCopyDesc::bytes, pxtask::GpuCopyDesc::isValid(), and PX_ASSERT.

void pxtask::GpuCopyDescQueue::flushEnqueued ( ) [inline]

Launch all copies queued since the last flush or reset.

void pxtask::GpuCopyDescQueue::operator= ( const GpuCopyDescQueue & ) [private]

void pxtask::GpuCopyDescQueue::reset	(	CUstream	stream,
		PxU32	reserveSize
	)			`[inline]`

Reset the enqueued copy descriptor list.

Must be called at least once before any copies are enqueued, and each time the launched copies are known to have been completed. The recommended use case is to call this at the start of each simulation step.
