From: Gert Wollny Date: Thu, 1 Nov 2018 11:59:24 +0000 (+0100) Subject: mesa/core: Add definitions and translations for EXT_texture_sRGB_R8 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b8e9c6522d8d1bc78be2bf1b411b22cc6615dbdf;p=mesa.git mesa/core: Add definitions and translations for EXT_texture_sRGB_R8 v2: - fix format definition line - disable for desktop GL - don't add GL_R8_EXT to glext.h since it is already in GLES2/gl2ext.h in glext.h and include this header where needed (all Emil) v3: - swrast: Fill the function table for sRGB_R8 The size of the function table is checked at compile time and must correspond to the number of mesa texture formats. dri/swrast being gles-2.0 doesn't support the extension though v4: - correct format layout comment (Ilia Mirkin) - correct logic for accepting GL_RED only textures (in part Ilia Mirkin) EXT_texture_sRGB_R8 requires OpenGL ES 3.0 which includes ARB_texture_rg/EXT_texture_rg, so one only must check for the first when SR8_EXT is really requested. v5: - add define for GL_ES8_XT to glheader.h and don't include GLES headers (Ilia Mirkin) Signed-off-by: Gert Wollny Reviewed-by: Ilia Mirkin --- diff --git a/src/mesa/main/extensions_table.h b/src/mesa/main/extensions_table.h index e3bf7c9fcee..a516a1b17f8 100644 --- a/src/mesa/main/extensions_table.h +++ b/src/mesa/main/extensions_table.h @@ -296,6 +296,7 @@ EXT(EXT_texture_object , dummy_true EXT(EXT_texture_rectangle , NV_texture_rectangle , GLL, x , x , x , 2004) EXT(EXT_texture_rg , ARB_texture_rg , x , x , x , ES2, 2011) EXT(EXT_texture_sRGB , EXT_texture_sRGB , GLL, GLC, x , x , 2004) +EXT(EXT_texture_sRGB_R8 , EXT_texture_sRGB_R8 , x , x , x , 30, 2015) EXT(EXT_texture_sRGB_decode , EXT_texture_sRGB_decode , GLL, GLC, x , 30, 2006) EXT(EXT_texture_shared_exponent , EXT_texture_shared_exponent , GLL, GLC, x , x , 2004) EXT(EXT_texture_snorm , EXT_texture_snorm , GLL, GLC, x , x , 2009) diff --git a/src/mesa/main/formats.c b/src/mesa/main/formats.c index d4cd5d2182c..cf2d2bc555a 100644 --- a/src/mesa/main/formats.c +++ b/src/mesa/main/formats.c @@ -1108,6 +1108,7 @@ _mesa_uncompressed_format_to_type_and_comps(mesa_format format, *comps = 4;
