A Fence or a group of fences are transfered to/from + * userspace using Sync File fds and there are two DRM properties for that. + * IN_FENCE_FD on each DRM Plane to send fences to the kernel and + * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel. + * + * As a contrast, with implicit fencing the kernel keeps track of any + * ongoing rendering, and automatically ensures that the atomic update waits + * for any pending rendering to complete. For shared buffers represented with + * a &struct dma_buf this is tracked in &struct reservation_object. + * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org), + * whereas explicit fencing is what Android wants. + * + * "IN_FENCE_FD”: + * Use this property to pass a fence that DRM should wait on before + * proceeding with the Atomic Commit request and show the framebuffer for + * the plane on the screen. The fence can be either a normal fence or a + * merged one, the sync_file framework will handle both cases and use a + * fence_array if a merged fence is received. Passing -1 here means no + * fences to wait on. + * + * If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag + * it will only check if the Sync File is a valid one. + * + * On the driver side the fence is stored on the @fence parameter of + * &struct drm_plane_state. Drivers which also support implicit fencing + * should set the implicit fence using drm_atomic_set_fence_for_plane(), + * to make sure there's consistent behaviour between drivers in precedence + * of implicit vs. explicit fencing. + * + * "OUT_FENCE_PTR”: + * Use this property to pass a file descriptor pointer to DRM. Once the + * Atomic Commit request call returns OUT_FENCE_PTR will be filled with + * the file descriptor number of a Sync File. This Sync File contains the + * CRTC fence that will be signaled when all framebuffers present on the + * Atomic Commit * request for that given CRTC are scanned out on the + * screen. + * + * The Atomic Commit request fails if a invalid pointer is passed. If the + * Atomic Commit request fails for any other reason the out fence fd + * returned will be -1. On a Atomic Commit with the + * DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1. + * + * Note that out-fences don't have a special interface to drivers and are + * internally represented by a &struct drm_pending_vblank_event in struct + * &drm_crtc_state, which is also used by the nonblocking atomic commit + * helpers and for the DRM event handling for existing userspace. + */ + +struct drm_out_fence_state { + s32 __user *out_fence_ptr;

Like e.g. vmw_kms_set_config does, to work around some vmwgfx userspace not clearing its ioctl structs properly. But you can't use it to augment semantics and put in additional checks, since from a correctly working userspace's pov there should not be any difference in behaviour between the legacy and the atomic paths. vmwgfx seems to be doing some strange things in its page_flip handlers. Since I'm not an expert of this codebase just wrap some FIXME comments around the potentially problematic code.
