From 76aed4b070be8950fd8ea5caff59321885ff0a06 Mon Sep 17 00:00:00 2001 From: Jakob Bornecrantz Date: Sat, 29 May 2010 11:33:14 +0200 Subject: [PATCH] gallium: Add drm driver interface This interfacre replaces the drm_api api it works very much the same way as drm_api but with the exception that its meant for the target to implement it. And it does not export a get function and neither a destroy function. --- .../include/state_tracker/drm_driver.h | 71 +++++++++++++++++++ 1 file changed, 71 insertions(+) create mode 100644 src/gallium/include/state_tracker/drm_driver.h diff --git a/src/gallium/include/state_tracker/drm_driver.h b/src/gallium/include/state_tracker/drm_driver.h new file mode 100644 index 00000000000..d94c1e6a7cf --- /dev/null +++ b/src/gallium/include/state_tracker/drm_driver.h @@ -0,0 +1,71 @@ + +#ifndef _DRM_DRIVER_H_ +#define _DRM_DRIVER_H_ + +#include "pipe/p_compiler.h" + +struct pipe_screen; +struct pipe_winsys; +struct pipe_context; +struct pipe_resource; + +#define DRM_API_HANDLE_TYPE_SHARED 0 +#define DRM_API_HANDLE_TYPE_KMS 1 + +/** + * For use with pipe_screen::{texture_from_handle|texture_get_handle}. + */ +struct winsys_handle +{ + /** + * Unused for texture_from_handle, always + * DRM_API_HANDLE_TYPE_SHARED.
