From 1e5014f7dfabcaf1f4b5608eb08e97179446eb09 Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Thu, 27 Aug 2009 18:57:29 +0100 Subject: drm_api: Operate on textures instead of buffers Most use cases just got the buffer from the texture and then called into one of the get_handle functions. Also with this patch it would be easier to move to a generic function for getting handles from textures and textures from handles, that is exposed via the screen. --- src/gallium/drivers/identity/id_drm.c | 90 +++++++++++++++-------------------- 1 file changed, 38 insertions(+), 52 deletions(-) (limited to 'src/gallium/drivers/identity') diff --git a/src/gallium/drivers/identity/id_drm.c b/src/gallium/drivers/identity/id_drm.c index e5342ac06e..14f68ac0d0 100644 --- a/src/gallium/drivers/identity/id_drm.c +++ b/src/gallium/drivers/identity/id_drm.c @@ -29,6 +29,7 @@ #include "util/u_memory.h" #include "identity/id_drm.h" +#include "identity/id_screen.h" #include "identity/id_public.h" #include "identity/id_screen.h" #include "identity/id_objects.h" @@ -79,81 +80,59 @@ identity_drm_create_context(struct drm_api *_api, return pipe;
