From: Jakob Bornecrantz Date: Mon, 15 Feb 2010 17:17:30 +0000 (+0000) Subject: gallium: Expose a opaque winsys handle and functions on pipe_screen X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b2e94d05c9602e2814a513a51eed67d014b338f3;p=mesa.git gallium: Expose a opaque winsys handle and functions on pipe_screen Instead of having these functions on a side interface like on drm_api create a opaque winsys_handle that is to be passed down into the winsys. Currently the only thing ported to this new interface is drm_api, and of that only the components that builds by default is ported. All the drivers and any extra state trackers needs to be ported before this can go into master. --- diff --git a/src/gallium/drivers/identity/id_drm.c b/src/gallium/drivers/identity/id_drm.c index f258c38cd71..936ccc444a8 100644 --- a/src/gallium/drivers/identity/id_drm.c +++ b/src/gallium/drivers/identity/id_drm.c @@ -63,62 +63,6 @@ identity_drm_create_screen(struct drm_api *_api, int fd, return identity_screen_create(screen);
