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/winsys/xlib/xlib_cell.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/gallium/winsys/xlib/xlib_cell.c') diff --git a/src/gallium/winsys/xlib/xlib_cell.c b/src/gallium/winsys/xlib/xlib_cell.c index 40bcdfe42a..a5dbdf30f6 100644 --- a/src/gallium/winsys/xlib/xlib_cell.c +++ b/src/gallium/winsys/xlib/xlib_cell.c @@ -243,7 +243,7 @@ xm_buffer_create(struct pipe_winsys *pws, { struct xm_buffer *buffer = CALLOC_STRUCT(xm_buffer); - buffer->base.refcount = 1; + pipe_reference_init(&buffer->base.reference, 1); buffer->base.alignment = alignment; buffer->base.usage = usage; buffer->base.size = size; @@ -267,7 +267,7 @@ static struct pipe_buffer * xm_user_buffer_create(struct pipe_winsys *pws, void *ptr, unsigned bytes) { struct xm_buffer *buffer = CALLOC_STRUCT(xm_buffer); - buffer->base.refcount = 1; + pipe_reference_init(&buffer->base.reference, 1); buffer->base.size = bytes; buffer->userBuffer = TRUE; buffer->data = ptr; -- cgit v1.2.3
