[Mesa-dev] [PATCH 0/3] Gallium: CopyBufferSubData basic accel

[Marek Olšák]

Hi,

This little series implements CopyBufferSubData via resource_copy_region and adds a fallback implementation to all drivers. Now drivers can implement a fast path for CopyBufferSubData instead of always defaulting to the software path.

I have tested this series with glean/bufferObject on r600g, softpipe, and llvmpipe. Please review.

Marek Olšák (3):
      util: add a simple memcpy path for copying buffers in util_resource_copy_region
      gallium: add fallback for copying buffers to all drivers
      st/mesa: implement CopyBufferSubData using resource_copy_region
