Detailed Description

any device-specific data, such as optix handles, cuda device pointers, etc. this is a virtual base class whose derived classes will do the actual work

Constructor & Destructor Documentation

DeviceData()

owl::DeviceBuffer::DeviceData::DeviceData	(	DeviceBuffer *	parent,
		const DeviceContext::SP &	device
	)

any device-specific data, such as optix handles, cuda device pointers, etc

~DeviceData()

owl::DeviceBuffer::DeviceData::~DeviceData ( )

virtual

destructor that releases any still-alloced memory

Member Function Documentation

clear()

virtual void owl::DeviceBuffer::DeviceData::clear ( )

pure virtual

clear the buffer by setting its contents to zero

Implemented in owl::DeviceBuffer::DeviceDataForTextures, owl::DeviceBuffer::DeviceDataForBuffers, owl::DeviceBuffer::DeviceDataForGroups, and owl::DeviceBuffer::DeviceDataForCopyableData.

executeResize()

virtual void owl::DeviceBuffer::DeviceData::executeResize ( )

pure virtual

executes the resize on the given device, including freeing old memory, and allocating required elemnts in device format, as required

Implemented in owl::DeviceBuffer::DeviceDataForTextures, owl::DeviceBuffer::DeviceDataForBuffers, owl::DeviceBuffer::DeviceDataForGroups, and owl::DeviceBuffer::DeviceDataForCopyableData.

uploadAsync()

virtual void owl::DeviceBuffer::DeviceData::uploadAsync ( const void *  hostDataPtr, size_t  offset, int64_t  count  )

pure virtual

create an async upload for data from the given host data pointer, using the given device's cuda stream, and doing any required translation from host-side data (eg, a texture object handle) to device-side data (ie, the cudaTextreObject_t for that device). this will not wait for the upload to complete, so an explicit cuda sync has to be done to ensure no race conditiosn will occur

Implemented in owl::DeviceBuffer::DeviceDataForTextures, owl::DeviceBuffer::DeviceDataForBuffers, owl::DeviceBuffer::DeviceDataForGroups, and owl::DeviceBuffer::DeviceDataForCopyableData.
