The dw_mipi_dsi_host_transfer() must return the number of bytes transmitted/received on success instead of 0. Note: As the read feature is not implemented, only the transmitted number of bytes is returned for the moment. Reviewed-by:

The dcs/generic dsi read feature is not yet implemented so it is important to warn the host_transfer() caller in case of read operation requests. Reviewed-by:

During a non-blocking commit, it is possible to return before the commit_tail work is queued (-ERESTARTSYS, for example). Since a reference on the crtc commit object is obtained for the pending vblank event when preparing the commit, the above situation will leave us with an extra reference. Therefore, if the commit_tail worker has not consumed the event at the end of a commit, release it's reference. Changes since v1: - Also check for state->event->base.completion being set, to handle the case where stall_checks() fails in setup_crtc_commit(). Changes since v2: - Add a flag to drm_crtc_commit, to prevent dereferencing a freed event. i915 may unreference the state in a worker.

We never support certain mode flags etc. Reject those early on in the mode_config.mode_valid() hook. That allows us to remove some duplicated checks from the connector .mode_valid() hooks, and it guarantees that we never see those flags even from user mode as the mode_config.mode_valid() hooks gets executed for those as well.

Allow drivers to provide a device wide .mode_valid() hook in addition to the already existing crtc/encoder/bridge/connector hooks. This can be used to validate device/driver wide constraings without having to add those to the other hooks. And since we call this hook also for user modes later on in the modeset we don't have to worry about anything the hook has already rejected. I also have some further ideas for this hook. Eg. we could replace the drm_mode_set_crtcinfo(HALVE_V) call in drm_mode_convert_umode()/etc. with a driver specific variant via this hook. At least on i915 we would like to pass CRTC_STEREO_DOUBLE to that function instead, and then we could safely use the crtc_ timings in all our .mode_valid() hooks, which would allow us to reuse those hooks for validating the adjusted_mode during a modeset. v2: Fix the language fails in the kernel docs (Daniel) Signed-off-by:

For some reason drm_mode_set_crtcinfo() does nothing if the mode has the DRM_MODE_TYPE_BUILTIN flag set without the other bit from DRM_MODE_TYPE_CRTC_C also set. I have zero idea what that is supposed to achieve, but since we have no users for neither flag bit let's kill this nonsense off. v2: Fix typo in commit message Signed-off-by:

Reject any mode with DRM_MODE_FLAG_BCAST. We have no code that even checks for this flag hence it can't possibly do any good. I think this maybe originated from fbdev where it was supposed to indicate PAL/NTSC broadcast timings. I have no idea why those would have to be identified by a flag rather than by just the timings themselves. And then I assume it got copied into xfree86 for fbdevhw, and later on it leaked into the randr protocol and kms uapi. Since kms fbdev emulation never uses the corresponding fbdev flag there should be no sane way for this to come back into kms via userspace either.

Reject any mode with DRM_MODE_FLAG_PIXMUX. We have no code that even checks for this flag hence it can't possibly do any good. Looks like this flag had something to do the the controller<->ramdac interface with some ancient S3 graphics adapters. Why someone though it would be a good idea to expose it directly to users I don't know. And later on it got copied into the randr protocol and kms uapi.

We use 32bit bitmasks to track planes/crtcs/encoders/connectors. Naturally we can only do that if the index of those objects stays below 32. Issue a warning whenever we exceed that limit, hopefully prompting someone to fix the problem. For connectors the issue is a bit more complicated as they can be created/destroyed at runtime due to MST. So the problem is no longer a purely theoretical programmer error. As the connector indexes are allocated via ida, we can simply limit the maximum value the ida is allowed to hand out. The error handling is already in place. v2: Return an error to the caller (Harry) v3: Print a debug message so that we know what happened (Maarten) Cc: Harry Wentland <harry.wentland@amd.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by:

Our various planes have a configurable zpos, that combined with the pipes allow to configure the composition. Since the interaction between the pipes, zpos and alphas framebuffers is not trivial, let's just enable the zpos as an immutable property for now, and use that zpos in our atomic_update part.
