From 5e27cd46c04a9e7b5904cc014bffd0f4daae31fe Mon Sep 17 00:00:00 2001 From: Michel Dänzer Date: Wed, 4 Mar 2009 11:58:48 +0100 Subject: gallium: Unify reference counting. The core reference counting code is centralized in p_refcnt.h. This has some consequences related to struct pipe_buffer: * The screen member of struct pipe_buffer must be initialized, or pipe_buffer_reference() will crash trying to destroy a buffer with reference count 0. u_simple_screen takes care of this, but I may have missed some of the drivers not using it. * Except for rare exceptions deep in winsys code, buffers must always be allocated via pipe_buffer_create() or via screen->*buffer_create() rather than via winsys->*buffer_create(). --- src/gallium/include/pipe/internal/p_winsys_screen.h | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/gallium/include/pipe/internal/p_winsys_screen.h') diff --git a/src/gallium/include/pipe/internal/p_winsys_screen.h b/src/gallium/include/pipe/internal/p_winsys_screen.h index 8d3bab0caa1..f4a29e63c7e 100644 --- a/src/gallium/include/pipe/internal/p_winsys_screen.h +++ b/src/gallium/include/pipe/internal/p_winsys_screen.h @@ -154,8 +154,7 @@ struct pipe_winsys void (*buffer_unmap)( struct pipe_winsys *ws, struct pipe_buffer *buf ); - void (*buffer_destroy)( struct pipe_winsys *ws, - struct pipe_buffer *buf ); + void (*buffer_destroy)( struct pipe_buffer *buf ); /** Set ptr = fence, with reference counting */ -- cgit v1.2.3
