From fc16ba8553e239acf68c6ea5f9729c4f02b2ffc4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jos=C3=A9=20Fonseca?= Date: Mon, 22 Dec 2008 20:20:58 +0000 Subject: [PATCH] softpipe: Call surface_alloc_storage to get the pipebuffer for display targets. Otherwise blitting from display target surfaces to front screen fails in several platforms. --- src/gallium/drivers/softpipe/sp_texture.c | 49 ++++++++++++++++------- 1 file changed, 34 insertions(+), 15 deletions(-) diff --git a/src/gallium/drivers/softpipe/sp_texture.c b/src/gallium/drivers/softpipe/sp_texture.c index 0cb4b2f03c3..fbe73e69152 100644 --- a/src/gallium/drivers/softpipe/sp_texture.c +++ b/src/gallium/drivers/softpipe/sp_texture.c @@ -94,31 +94,50 @@ softpipe_texture_layout(struct pipe_screen *screen, return spt->buffer != NULL; } +/* Hack it up to use the old winsys->surface_alloc_storage() + * method for now: + */ static boolean softpipe_displaytarget_layout(struct pipe_screen *screen, struct softpipe_texture * spt) { struct pipe_winsys *ws = screen->winsys; - size_t tex_size; - unsigned cpp; - - switch (spt->base.format) { - case PIPE_FORMAT_R5G6B5_UNORM: - cpp = 2; - break; - case PIPE_FORMAT_Z24S8_UNORM: - case PIPE_FORMAT_A8R8G8B8_UNORM: - default: - cpp = 4; - break; + struct pipe_surface surf; + unsigned flags = (PIPE_BUFFER_USAGE_CPU_READ | + PIPE_BUFFER_USAGE_CPU_WRITE | + PIPE_BUFFER_USAGE_GPU_READ | + PIPE_BUFFER_USAGE_GPU_WRITE); + int ret; + + + memset(&surf, 0, sizeof(surf)); + + ret =ws->surface_alloc_storage( ws, + &surf, + spt->base.width[0], + spt->base.height[0], + spt->base.format, + flags, + spt->base.tex_usage); + if(ret != 0) + return FALSE; + + if (!surf.buffer) { + /* allocation failed */ + return FALSE; } - tex_size = spt->base.width[0] * cpp * spt->base.height[0]; - spt->buffer = ws->buffer_create(ws, 64, PIPE_BUFFER_USAGE_PIXEL, tex_size); + /* Now extract the goodies: */ spt->base.nblocksx[0] = pf_get_nblocksx(&spt->base.block, spt->base.width[0]); spt->base.nblocksy[0] = pf_get_nblocksy(&spt->base.block, spt->base.height[0]); - spt->stride[0] = spt->base.width[0] * cpp; + spt->stride[0] = surf.stride; + + /* Transfer the reference: + */ + spt->buffer = surf.buffer; + surf.buffer = NULL; + return spt->buffer != NULL; } -- 2.30.2
