This is for the non-zero-copy case.. for example pixels live in gl texture in host (vmwgfx/virtgl), or in vram for discrete gpu perhaps (or some tiled format, etc). Since in those cases, you have to copy part of the buffer, as specified by the bounding box, to and/or from staging buffer (based

[Mesa-dev] [PATCH 4/4] gbm: Add map/unmap functions

This adds map and unmap functions to GBM utilizing the DRIimage extension mapImage/unmapImage functions or existing internal mapping for dumb buffers. Unlike prior attempts, this version provides a region to map and usage flags for the mapping. The operation follows the same semantics as the
