From bddf275db44695e3850c4b62b8f4b77d93299ae9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Thu, 2 Jun 2011 00:50:45 +0200 Subject: [PATCH] softpipe: add a better fake implementation of fences The flush function, when asked for, should not return a NULL fence. NULL can only be returned if fences are not implemented, and st/mesa doesn't call any of the fence functions if it receives a NULL fence (because some drivers don't even set the fence hooks). ARB_sync is exposed if fence_finish is set. --- src/gallium/drivers/softpipe/sp_fence.c | 7 +++---- src/gallium/drivers/softpipe/sp_flush.c | 4 ++-- 2 files changed, 5 insertions(+), 6 deletions(-) diff --git a/src/gallium/drivers/softpipe/sp_fence.c b/src/gallium/drivers/softpipe/sp_fence.c index 7b79a0df4ea..c2897ed1ef8 100644 --- a/src/gallium/drivers/softpipe/sp_fence.c +++ b/src/gallium/drivers/softpipe/sp_fence.c @@ -36,8 +36,7 @@ softpipe_fence_reference(struct pipe_screen *screen, struct pipe_fence_handle **ptr, struct pipe_fence_handle *fence) { - assert(!*ptr); - assert(!fence); + *ptr = fence; } @@ -45,7 +44,7 @@ static boolean softpipe_fence_signalled(struct pipe_screen *screen, struct pipe_fence_handle *fence) { - assert(!fence); + assert(fence); return TRUE; } @@ -55,7 +54,7 @@ softpipe_fence_finish(struct pipe_screen *screen, struct pipe_fence_handle *fence, uint64_t timeout) { - assert(!fence); + assert(fence); return TRUE; } diff --git a/src/gallium/drivers/softpipe/sp_flush.c b/src/gallium/drivers/softpipe/sp_flush.c index 720fea83cb2..a2733e95878 100644 --- a/src/gallium/drivers/softpipe/sp_flush.c +++ b/src/gallium/drivers/softpipe/sp_flush.c @@ -96,9 +96,9 @@ softpipe_flush( struct pipe_context *pipe, ++frame_no; } #endif - + if (fence) - *fence = NULL; + *fence = (void*)(intptr_t)1; } void -- 2.30.2
