I think in practice, every hw driver can support both for texturing if it can support one, since swizzles are always possible (due to ARB_texture_swizzle). In practice at least nouveau prior to Mario's patches only supported it one way. I just checked r600, radeonsi, i965 and freedreno, and they appear to support both for texturing. I think that covers the majority of the likely 10bpc users. -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
