|
+ * or driver doesn't support. This includes but is of course not limited
|
|
|
+ * to:
|
|
|
+ *
|
|
|
+ * - Checking that the modes, framebuffers, scaling and placement
|
|
|
+ * requirements and so on are within the limits of the hardware.
|
|
|
+ *
|
|
|
+ * - Checking that any hidden shared resources are not oversubscribed.
|
|
|
+ * This can be shared PLLs, shared lanes, overall memory bandwidth,
|
|
|
+ * display fifo space (where shared between planes or maybe even
|
|
|
+ * CRTCs).
|
|
|
+ *
|
|
|
+ * - Checking that virtualized resources exported to userspace are not
|
|
|
+ * oversubscribed. For various reasons it can make sense to expose
|
|
|
+ * more planes, crtcs or encoders than which are physically there. One
|
|
|
+ * example is dual-pipe operations (which generally should be hidden
|
|
|
+ * from userspace if when lockstepped in hardware, exposed otherwise),
|
|
|
+ * where a plane might need 1 hardware plane (if it's just on one
|
|
|
+ * pipe), 2 hardware planes (when it spans both pipes) or maybe even
|
|
|
+ * shared a hardware plane with a 2nd plane (if there's a compatible
|
|
|
+ * plane requested on the area handled by the other pipe).
|
|
|
+ *
|
|
|
+ * - Check that any transitional state is possible and that if
|
|
|
+ * requested, the update can indeed be done in the vblank period
|
|
|
+ * without temporarily disabling some functions.
|
|
|
+ *
|
|
|
+ * - Check any other constraints the driver or hardware might have.
|
|
|
+ *
|
|
|
+ * - This callback also needs to correctly fill out the &drm_crtc_state
|
|
|
+ * in this update to make sure that drm_atomic_crtc_needs_modeset()
|
|
|
+ * reflects the nature of the possible update and returns true if and
|
|
|
+ * only if the update cannot be applied without tearing within one
|
|
|
+ * vblank on that CRTC. The core uses that information to reject
|
|
|
+ * updates which require a full modeset (i.e. blanking the screen, or
|
|
|
+ * at least pausing updates for a substantial amount of time) if
|
|
|
+ * userspace has disallowed that in its request.
|
|
|
+ *
|
|
|
+ * - The driver also does not need to repeat basic input validation
|
|
|
+ * like done for the corresponding legacy entry points. The core does
|
|
|
+ * that before calling this hook.
