This sample demonstrates the use of EnqueueRequests() and the destination type
DSTORAGE_REQUEST_DESTINATION_MULTIPLE_SUBRESOURCES_RANGE. In this demo, a quad
is textured with a reserved (tiled) resource containing a full mip chain. The
currently visible mip level is mapped and unmapped to the reserved resource on
demand. You can change the visible mip by pressing the arrow keys.
The sample synchronizes the execution of
ID3D12CommandQueue::UpdateTileMappings() with requests enqueued on the
DirectStorage queue using the new EnqueueRequests() API. This ensures that the
reserved resource is not written to until the tile locations are mapped to
memory locations in a resource heap. The sample also demonstrates the new
DirectStorage request destination type,
DSTORAGE_REQUEST_DESTINATION_MULTIPLE_SUBRESOURCES_RANGE, which allows a
specific range of subresources to be written to.
This demo is based on the D3D12ReservedResources sample.
