From 5e27cd46c04a9e7b5904cc014bffd0f4daae31fe Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michel=20D=C3=A4nzer?= 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/drivers/nv10/nv10_prim_vbuf.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/gallium/drivers/nv10/nv10_prim_vbuf.c') diff --git a/src/gallium/drivers/nv10/nv10_prim_vbuf.c b/src/gallium/drivers/nv10/nv10_prim_vbuf.c index 491a881806..089c236302 100644 --- a/src/gallium/drivers/nv10/nv10_prim_vbuf.c +++ b/src/gallium/drivers/nv10/nv10_prim_vbuf.c @@ -106,11 +106,11 @@ nv10_vbuf_render_allocate_vertices( struct vbuf_render *render, { struct nv10_vbuf_render *nv10_render = nv10_vbuf_render(render); struct nv10_context *nv10 = nv10_render->nv10; - struct pipe_winsys *winsys = nv10->pipe.winsys; + struct pipe_screen *screen = nv10->pipe.screen; size_t size = (size_t)vertex_size * (size_t)nr_vertices; assert(!nv10_render->buffer); - nv10_render->buffer = winsys->buffer_create(winsys, 64, PIPE_BUFFER_USAGE_VERTEX, size); + nv10_render->buffer = screen->buffer_create(screen, 64, PIPE_BUFFER_USAGE_VERTEX, size); nv10->dirty |= NV10_NEW_VTXARRAYS; @@ -206,7 +206,7 @@ nv10_vbuf_render_release_vertices( struct vbuf_render *render ) struct pipe_screen *pscreen = &nv10->screen->pipe; assert(nv10_render->buffer); - pipe_buffer_reference(pscreen, &nv10_render->buffer, NULL); + pipe_buffer_reference(&nv10_render->buffer, NULL); } -- cgit v1.2.3
