Detailed Description

device-data for a device buffer like other device buffers, but containing texture objects - ie, these are Texture::SP on the host, but get translated to cudaTextureObject_t's upon upload

Member Function Documentation

clear()

void owl::DeviceBuffer::DeviceDataForTextures::clear ( )

overridevirtual

clear the buffer by setting its contents to zero

Implements owl::DeviceBuffer::DeviceData.

executeResize()

void owl::DeviceBuffer::DeviceDataForTextures::executeResize ( )

overridevirtual

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

Implements owl::DeviceBuffer::DeviceData.

uploadAsync()

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

overridevirtual

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

Implements owl::DeviceBuffer::DeviceData.

Member Data Documentation

hostHandles

std::vector<Texture::SP> owl::DeviceBuffer::DeviceDataForTextures::hostHandles

this is used only for buffers over object types (bufers of textures, or buffers of buffers). For those buffers, we use this vector to store host-side handles of the objects in this buffer, to ensure proper recounting
