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_miptree.c | 41 +++++++++++--------------------- src/gallium/drivers/nv50/nv50_program.c | 6 ++--- src/gallium/drivers/nv50/nv50_query.c | 6 ++--- src/gallium/drivers/nv50/nv50_screen.c | 6 ++--- src/gallium/drivers/nv50/nv50_transfer.c | 13 ++++------ 5 files changed, 27 insertions(+), 45 deletions(-) (limited to 'src/gallium/drivers/nv50') diff --git a/src/gallium/drivers/nv50/nv50_miptree.c b/src/gallium/drivers/nv50/nv50_miptree.c index 24a68b7235..dc4688ccdc 100644 --- a/src/gallium/drivers/nv50/nv50_miptree.c +++ b/src/gallium/drivers/nv50/nv50_miptree.c @@ -29,7 +29,6 @@ static struct pipe_texture * nv50_miptree_create(struct pipe_screen *pscreen, const struct pipe_texture *tmp) { - struct pipe_winsys *ws = pscreen->winsys;
