From: Sinclair Yeh Date: Thu, 23 Mar 2017 18:36:05 +0000 (-0700) Subject: drm/vmwgfx: Plane atomic state X-Git-Tag: v4.14-rc1~674^2~25^2~18 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cc5ec459de323fe32514d5f47a4d00460ee30f7b;p=platform%2Fkernel%2Flinux-rpi3.git drm/vmwgfx: Plane atomic state Add plane state handling functions. We have to keep track of a few plane states so we cannot use the DRM helper for this. Created vmw_plane_state along with functions to reset, duplicate, and destroty it. v2 * Removed cursor clean up special case Signed-off-by: Sinclair Yeh Reviewed-by: Thomas Hellstrom Acked-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c index 18bd8dc..ec05067 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_kms.c @@ -468,6 +468,96 @@ vmw_du_crtc_destroy_state(struct drm_crtc *crtc, } +/** + * vmw_du_plane_duplicate_state - duplicate plane state + * @plane: drm plane + * + * Allocates and returns a copy of the plane state (both common and + * vmw-specific) for the specified plane. + * + * Returns: The newly allocated plane state, or NULL on failure. + */ +struct drm_plane_state * +vmw_du_plane_duplicate_state(struct drm_plane *plane) +{ + struct drm_plane_state *state;
