X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f56dfc32134d65599159f53215713bf372c51a13;p=mesa.git i965: Support MESA_FORMAT_SIGNED_RGBA_16. The hardware supports this format with no known quirks, so we may as well enable it. Alpha blending is not supported until Sandybridge, but as far as I can tell, OpenGL doesn't require alpha blending on SNORM formats. Plus, we already expose R8G8B8A8_SNORM which has a similar restriction. Fixes 6 piglit texwrap-2D-*SNORM* cases, gl-3.1/required-sized-texture-formats, and 10 oglconform snorm-textures subcases Signed-off-by: Kenneth Graunke Reviewed-by: Eric Anholt --- diff --git a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c index 65ca2fc3f5e..8bb041078d8 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c @@ -430,7 +430,7 @@ brw_format_for_mesa_format(gl_format mesa_format) [MESA_FORMAT_SIGNED_R16] = BRW_SURFACEFORMAT_R16_SNORM, [MESA_FORMAT_SIGNED_GR1616] = BRW_SURFACEFORMAT_R16G16_SNORM, [MESA_FORMAT_SIGNED_RGB_16] = 0, - [MESA_FORMAT_SIGNED_RGBA_16] = 0, + [MESA_FORMAT_SIGNED_RGBA_16] = BRW_SURFACEFORMAT_R16G16B16A16_SNORM, [MESA_FORMAT_RGBA_16] = BRW_SURFACEFORMAT_R16G16B16A16_UNORM, [MESA_FORMAT_RED_RGTC1] = BRW_SURFACEFORMAT_BC4_UNORM,
