From b7e246d89afb2c6072fd65f6bf01a1921afc6d2a Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 12 Feb 2016 13:12:09 -0500 Subject: [PATCH] mesa: recognize enums GL_COLOR_ATTACHMENT8-31 as valid Similar as for AUX1-3, these enums aren't invalid (i.e. -1) but also not supported by mesa. Returning BUFFER_COUNT causes the proper error to be returned by ReadBuffer and other functions. This resolves some failures in dEQP-GLES31.functional.debug.negative_coverage.get_error.buffer.read_buffer Signed-off-by: Ilia Mirkin Reviewed-by: Brian Paul --- src/mesa/main/buffers.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/src/mesa/main/buffers.c b/src/mesa/main/buffers.c index 83e238a..3ca4b66 100644 --- a/src/mesa/main/buffers.c +++ b/src/mesa/main/buffers.c @@ -159,6 +159,9 @@ draw_buffer_enum_to_bitmask(const struct gl_context *ctx, GLenum buffer) case GL_COLOR_ATTACHMENT7_EXT: return BUFFER_BIT_COLOR7; default: + /* not an error, but also not supported */ + if (buffer >= GL_COLOR_ATTACHMENT8 && buffer <= GL_COLOR_ATTACHMENT31) + return 1 << BUFFER_COUNT; /* error */ return BAD_MASK; } @@ -214,6 +217,9 @@ read_buffer_enum_to_index(GLenum buffer) case GL_COLOR_ATTACHMENT7_EXT: return BUFFER_COLOR7; default: + /* not an error, but also not supported */ + if (buffer >= GL_COLOR_ATTACHMENT8 && buffer <= GL_COLOR_ATTACHMENT31) + return BUFFER_COUNT; /* error */ return -1; } -- 2.7.4
