drm_plane_state->src might be modified by the driver. This is done e.g. in i915 driver when there is bigger framebuffer than the plane and there is some offset within framebuffer. I915 driver calculates separate offset and adjusts src rect coords to be relative to this offset. Damage clips are still relative to original src coords provided by user-space. This patch ensures original coordinates provided by user-space are used when initiliazing damage iterator. Signed-off-by:

It's better to perform the sync at the very last of the suspend instead of the pipe-disable function, so that we can catch all pending URBs (if any). While we're at it, drop the error code from udl_sync_pending_urb() since we basically ignore it; instead, give a clear error message indicating a problem. Acked-by:

udl_alloc_urb_list() retires the allocation if there is no enough room left, and it reinitializes the stuff unnecessarily such as the linked list head and the waitqueue, which could be harmful. Those should be outside the retry loop. Acked-by:
-
Takashi Iwai authored
In the current design, udl_get_urb() may be called asynchronously during the driver freeing its URL list via udl_free_urb_list(). The problem is that the sync is determined by comparing the urbs.count and urbs.available fields, while we clear urbs.count field only once after udl_free_urb_list() finishes, i.e. during udl_free_urb_list(), the state becomes inconsistent. For fixing this inconsistency and also for hardening the locking scheme, this patch does a slight refactoring of the code around udl_get_urb() and udl_free_urb_list(). Now urbs.count is updated in the same spinlock at extracting a URB from the list in udl_free_url_list(). Acked-by:

Takashi Iwai authored
Restore the display mode whne resuming from suspend. Currently, the display remains dark. On resume, the CRTC's mode does not change, but the 'active' flag changes to 'true'. Taking this into account when considering a mode switch restores the display mode. The bug is reproducable by using Gnome with udl and observing the adapter's suspend/resume behavior. Actually, the whole check added in udl_simple_display_pipe_enable() about the crtc_state->mode_changed was bogus. We should drop the whole check and always apply the mode change in this function.

When an MST connector stays enabled during a commit the connector's MST state needs to be added to the atomic state, but the corresponding MST payload allocation shouldn't be set for deletion; fix such modesets by ensuring the above even if the connector was already enabled before the modeset.

Javier Martinez Canillas authored
The simple display pipeline is a set of helpers that can be used by DRM drivers to avoid dealing with all the needed components and just define a few functions to operate a simple display device with one full-screen scanout buffer feeding a single output. But it is arguable that this provides the correct level of abstraction for simple drivers, and recently some have been ported from using these simple display helpers to use the regular atomic helpers instead. The rationale for this is that the simple display pipeline helpers don't hide that much of the DRM complexity, while adding an indirection layer that conflates the concepts of CRTCs and planes. This makes the helpers less flexible and harder to be reused among different graphics drivers. Also, for simple drivers, using the full atomic helpers doesn't require a lot of additional code. So adding a simple display pipeline layer may not be worth it. For these reasons, let's follow that trend and make ssd130x a plain DRM driver that creates its own primary plane, CRTC, enconder and connector. Suggested-by:
