This class implements a dedicated upload queue for uploading data to device resources in its own thread. It's using idea of ring buffer for staging memory. It supports buffer data uploading.
uint64_t AZ::Metal::AsyncUploadQueue::QueueUpload | ( | const RHI::BufferStreamRequest & | request | ) |
Queue copy commands to upload buffer resource
RHI::AsyncWorkHandle AZ::Metal::AsyncUploadQueue::QueueUpload | ( | const RHI::StreamingImageExpandRequest & | request, |
uint32_t | residentMip | ||
) |
Queue copy commands to upload image subresources.
residentMip | is the resident mip level the expand request starts from. |
