Detailed Description

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

Constructor & Destructor Documentation

PxGpuCopyDescQueue::PxGpuCopyDescQueue ( PxGpuDispatcher &  d )

inline

PxGpuCopyDescQueue constructor.

PxGpuCopyDescQueue::~PxGpuCopyDescQueue ( )

inline

PxGpuCopyDescQueue destructor.

References PxCudaBufferMemorySpace::T_PINNED_HOST.

Member Function Documentation

void PxGpuCopyDescQueue::enqueue ( PxGpuCopyDesc &  desc )

inline

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

References PxGpuCopyDesc::bytes, PxGpuCopyDesc::isValid(), and PX_ASSERT.

void PxGpuCopyDescQueue::flushEnqueued ( )

inline

Launch all copies queued since the last flush or reset.

void PxGpuCopyDescQueue::operator= ( const PxGpuCopyDescQueue &  )

private

void PxGpuCopyDescQueue::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.
