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/drivers/nv50/nv50_query.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/gallium/drivers/nv50/nv50_query.c') diff --git a/src/gallium/drivers/nv50/nv50_query.c b/src/gallium/drivers/nv50/nv50_query.c index 7c8831a46de..a2c56f99a89 100644 --- a/src/gallium/drivers/nv50/nv50_query.c +++ b/src/gallium/drivers/nv50/nv50_query.c @@ -41,13 +41,13 @@ nv50_query(struct pipe_query *pipe) static struct pipe_query * nv50_query_create(struct pipe_context *pipe, unsigned type) { - struct pipe_winsys *ws = pipe->winsys; + struct pipe_screen *screen = pipe->winsys; struct nv50_query *q = CALLOC_STRUCT(nv50_query); assert (q->type == PIPE_QUERY_OCCLUSION_COUNTER); q->type = type; - q->buffer = ws->buffer_create(ws, 256, 0, 16); + q->buffer = screen->buffer_create(screen, 256, 0, 16); if (!q->buffer) { FREE(q); return NULL; @@ -62,7 +62,7 @@ nv50_query_destroy(struct pipe_context *pipe, struct pipe_query *pq) struct nv50_query *q = nv50_query(pq); if (q) { - pipe_buffer_reference(pipe->screen, &q->buffer, NULL); + pipe_buffer_reference(&q->buffer, NULL); FREE(q); } } -- cgit v1.2.3
