From: Roland Scheidegger <srol...@vmware.com> Since pipe_surface already has all the necessary fields no interface changes are necessary except adding a new shader semantic value (TGSI_SEMANTIC_LAYER), though add a pipe capability bit for it as well. (Note that what GL knows as "gl_Layer" variable d3d10 is naming "RENDER_TARGET_ARRAY_INDEX") --- src/gallium/docs/source/screen.rst | 2 ++ src/gallium/include/pipe/p_defines.h | 3 ++- src/gallium/include/pipe/p_shader_tokens.h | 3 ++- 3 files changed, 6 insertions(+), 2 deletions(-)
