From 2ae754b7b97c56709a7f12f017bf846a9e1456aa Mon Sep 17 00:00:00 2001 From: Pauli Nieminen Date: Sun, 21 Mar 2010 20:16:17 +0200 Subject: [PATCH] r200: Fix swtnl fallback to flush pending rendering before transition. Flush after transition would emit wrong state that could cause wrong state emited for pending rendering operation. Fixes wan once from extrement tuxracer that is using per vertex materials. --- src/mesa/drivers/dri/r200/r200_tcl.c | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-) diff --git a/src/mesa/drivers/dri/r200/r200_tcl.c b/src/mesa/drivers/dri/r200/r200_tcl.c index 159434427fa..46dce98871f 100644 --- a/src/mesa/drivers/dri/r200/r200_tcl.c +++ b/src/mesa/drivers/dri/r200/r200_tcl.c @@ -692,20 +692,30 @@ void r200TclFallback( GLcontext *ctx, GLuint bit, GLboolean mode ) GLuint oldfallback = rmesa->radeon.TclFallback; if (mode) { - rmesa->radeon.TclFallback |= bit; if (oldfallback == 0) { + /* We have to flush before transition */ + if ( rmesa->radeon.dma.flush ) + rmesa->radeon.dma.flush( rmesa->radeon.glCtx ); + if (R200_DEBUG & RADEON_FALLBACKS) fprintf(stderr, "R200 begin tcl fallback %s\n", getFallbackString( bit )); + rmesa->radeon.TclFallback |= bit; transition_to_swtnl( ctx ); - } + } else + rmesa->radeon.TclFallback |= bit; } else { - rmesa->radeon.TclFallback &= ~bit; if (oldfallback == bit) { + /* We have to flush before transition */ + if ( rmesa->radeon.dma.flush ) + rmesa->radeon.dma.flush( rmesa->radeon.glCtx ); + if (R200_DEBUG & RADEON_FALLBACKS) fprintf(stderr, "R200 end tcl fallback %s\n", getFallbackString( bit )); + rmesa->radeon.TclFallback &= ~bit; transition_to_hwtnl( ctx ); - } + } else + rmesa->radeon.TclFallback &= ~bit; } }
