[Mesa-dev] [PATCH 0/5] Implement ARB_copy_image on i965

[Jason Ekstrand]

This series implements ARB_copy_image in i965 in two steps:  First, we
provide a meta implementation that handles the cases when both textures are
uncompressed and we can leverage the already-existing code for
BlitFramebuffers.  The other case, when at least one texture is compressed,
is handled by calling into the blitter hardware.

Jason Ekstrand (5):
  Add GL API support for ARB_copy_image
  mesa/meta: Make _mesa_meta_bind_fbo_image also take a framebuffer
    target
  mesa/meta: Add support for storing the current read buffer
  mesa/meta: Add a partial implementation of CopyImageSubData
  i965: Add support for ARB_copy_image
