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/cell/ppu/cell_fence.c | 6 +-- src/gallium/drivers/cell/ppu/cell_texture.c | 65 ++++++++++------------------- 2 files changed, 25 insertions(+), 46 deletions(-) (limited to 'src/gallium/drivers/cell') diff --git a/src/gallium/drivers/cell/ppu/cell_fence.c b/src/gallium/drivers/cell/ppu/cell_fence.c index 32dbf5706c..13125a9fa3 100644 --- a/src/gallium/drivers/cell/ppu/cell_fence.c +++ b/src/gallium/drivers/cell/ppu/cell_fence.c @@ -96,7 +96,7 @@ cell_add_buffer_to_list(struct cell_context *cell, struct cell_buffer_node *node = CALLOC_STRUCT(cell_buffer_node); /* create new list node which references the buffer, insert at head */ if (node) { - pipe_buffer_reference(ps, &node->buffer, buffer); + pipe_buffer_reference(&node->buffer, buffer); node->next = list->head; list->head = node; } @@ -127,10 +127,10 @@ cell_free_fenced_buffers(struct cell_context *cell, pipe_buffer_unmap(ps, node->buffer); #if 0 printf("Unref buffer %p\n", node->buffer); - if (node->buffer->refcount == 1) + if (node->buffer->reference.count == 1) printf(" Delete!\n"); #endif - pipe_buffer_reference(ps, &node->buffer, NULL); + pipe_buffer_reference(&node->buffer, NULL); FREE(node); node = next; } diff --git a/src/gallium/drivers/cell/ppu/cell_texture.c b/src/gallium/drivers/cell/ppu/cell_texture.c index 74724393f7..bc6afa94a8 100644 --- a/src/gallium/drivers/cell/ppu/cell_texture.c +++ b/src/gallium/drivers/cell/ppu/cell_texture.c @@ -101,18 +101,17 @@ static struct pipe_texture * cell_texture_create(struct pipe_screen *screen, const struct pipe_texture *templat) { - struct pipe_winsys *ws = screen->winsys; struct cell_texture *ct = CALLOC_STRUCT(cell_texture); if (!ct) return NULL; ct->base = *templat; - ct->base.refcount = 1; + pipe_reference_init(&ct->base.reference, 1); ct->base.screen = screen; cell_texture_layout(ct); - ct->buffer = ws->buffer_create(ws, 32, PIPE_BUFFER_USAGE_PIXEL, + ct->buffer = screen->buffer_create(screen, 32, PIPE_BUFFER_USAGE_PIXEL, ct->buffer_size); if (!ct->buffer) { @@ -125,28 +124,18 @@ cell_texture_create(struct pipe_screen *screen, static void -cell_texture_release(struct pipe_screen *screen, - struct pipe_texture **pt) +cell_texture_destroy(struct pipe_texture *pt) { - if (!*pt) - return; - - if (--(*pt)->refcount <= 0) { - /* Delete this texture now. - * But note that the underlying pipe_buffer may linger... - */ - struct cell_texture *ct = cell_texture(*pt); + struct cell_texture *ct = cell_texture(pt); - if (ct->mapped) { - pipe_buffer_unmap(screen, ct->buffer); - ct->mapped = NULL; - } + if (ct->mapped) { + pipe_buffer_unmap(screen, ct->buffer); + ct->mapped = NULL; + } - pipe_buffer_reference(screen, &ct->buffer, NULL); + pipe_buffer_reference(&ct->buffer, NULL); - FREE(ct); - } - *pt = NULL; + FREE(ct); } @@ -291,7 +280,7 @@ cell_get_tex_surface(struct pipe_screen *screen, ps = CALLOC_STRUCT(pipe_surface); if (ps) { - ps->refcount = 1; + pipe_reference_init(&ps->reference, 1); pipe_texture_reference(&ps->texture, pt); ps->format = pt->format; ps->width = pt->width[level]; @@ -319,16 +308,10 @@ cell_get_tex_surface(struct pipe_screen *screen, static void -cell_tex_surface_release(struct pipe_screen *screen, - struct pipe_surface **s) +cell_tex_surface_destroy(struct pipe_surface *s) { - struct pipe_surface *surf = *s; - - if (--surf->refcount == 0) { - pipe_texture_reference(&surf->texture, NULL); - FREE(surf); - } - *s = NULL; + pipe_texture_reference(&surf->texture, NULL); + FREE(surf); } @@ -353,7 +336,7 @@ cell_get_tex_transfer(struct pipe_screen *screen, ctrans = CALLOC_STRUCT(cell_transfer); if (ctrans) { struct pipe_transfer *pt = &ctrans->base; - pt->refcount = 1; + pipe_reference_init(&pt->reference, 1); pipe_texture_reference(&pt->texture, texture); pt->format = texture->format; pt->block = texture->block; @@ -388,20 +371,16 @@ cell_get_tex_transfer(struct pipe_screen *screen, static void -cell_tex_transfer_release(struct pipe_screen *screen, - struct pipe_transfer **t) +cell_tex_transfer_destroy(struct pipe_transfer *t) { - struct cell_transfer *transfer = cell_transfer(*t); + struct cell_transfer *transfer = cell_transfer(t); /* Effectively do the texture_update work here - if texture images * needed post-processing to put them into hardware layout, this is * where it would happen.
