Author: Luca Barbieri <[email protected]> Date: Wed Sep 8 06:24:10 2010 +0200 mesa: add GL_CONTEXT_FLAG_ROBUST_ACCESS_BIT_ARB and env var to set it ARB_robustness specifies it, and we need the bit to choose whether to apply some loop optimizations in the GLSL compiler. Currenly, it is turned on by export MESA_ROBUST_ACCESS=1. In the future, GLX_ARB_create_context_robustness will allow to turn it on in the standard way. --- src/mesa/main/context.c | 5 +++++ src/mesa/main/mtypes.h | 4 ++++ 2 files changed, 9 insertions(+), 0 deletions(-) diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 979bc40..f5fe94d 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -873,6 +873,11 @@ _mesa_initialize_context_for_api(GLcontext *ctx, ctx->WinSysDrawBuffer = NULL; ctx->WinSysReadBuffer = NULL; + /* eventually, GLX_ARB_create_context_robustness will be usable to enable this too */ + if (_mesa_getenv("MESA_ROBUST_ACCESS")) { + ctx->Const.ContextFlags |= GL_CONTEXT_FLAG_ROBUST_ACCESS_BIT_ARB; + } + /* misc one-time initializations */ one_time_init(ctx); diff --git a/src/mesa/main/mtypes.h b/src/mesa/main/mtypes.h index cabc42b..d66a60f 100644 --- a/src/mesa/main/mtypes.h +++ b/src/mesa/main/mtypes.h @@ -3088,6 +3088,10 @@ typedef enum { API_OPENGLES2 } gl_api; +#ifndef GL_CONTEXT_FLAG_ROBUST_ACCESS_BIT_ARB +#define GL_CONTEXT_FLAG_ROBUST_ACCESS_BIT_ARB 0x00000004 +#endif + /** * Mesa rendering context. * _______________________________________________ mesa-commit mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/mesa-commit
