From 50b82ecd772ff8f59974618f852fedf98bbe77a6 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Sun, 24 Apr 2016 19:38:03 -0700 Subject: [PATCH] mesa/gles: Allow format GL_RED to be used with MESA_FORMAT_R_UNORM If the bound framebuffer has a format of MESA_FORMAT_R_UNORM, then IMPLEMENTATION_COLOR_READ_FORMAT will return GL_RED. This change applies to OpenGLES contexts where additional restrictions are placed on the formats that are allowed to be supported. Fixes OpenGLES 3.1 CTS tests: * ES31-CTS.texture_border_clamp.sampling_texture.Texture2DDC16 * ES31-CTS.texture_border_clamp.sampling_texture.Texture2DDC16Linear * ES31-CTS.texture_border_clamp.sampling_texture.Texture2DDC32F * ES31-CTS.texture_border_clamp.sampling_texture.Texture2DDC32FLinear Signed-off-by: Jordan Justen Reviewed-by: Kenneth Graunke --- src/mesa/main/framebuffer.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/src/mesa/main/framebuffer.c b/src/mesa/main/framebuffer.c index f69dc6cb3e6..38bd6806056 100644 --- a/src/mesa/main/framebuffer.c +++ b/src/mesa/main/framebuffer.c @@ -858,6 +858,8 @@ _mesa_get_color_read_format(struct gl_context *ctx) return GL_BGRA; else if (format == MESA_FORMAT_B5G6R5_UNORM) return GL_BGR; + else if (format == MESA_FORMAT_R_UNORM8) + return GL_RED; switch (data_type) { case GL_UNSIGNED_INT: -- 2.30.2
