Skip DDC probe for forced connector status. Don't try to read the EDID if the connector is forced off. Skipping probe for forced on connectors will make more sense when drm_do_get_edid() will handle override and firmware EDIDs. Suggested-by:

The warnings from parsing the EDID are not driver errors, but the "normal but significant" conditions from the external device. As such, they do not need the ferocity of an *ERROR*, but can use the less harsh DRM_NOTE instead. Signed-off-by:

Most DRM messages include three pieces of information: the type of the component (CRTC, ENCODER, CONNECTOR etc), the DRM object ID of the component, and the component name. However, there are some messages which omit the last piece of identifying information. This makes it harder to debug failures when these messages are printed, because the DRM object ID doesn't supply enough information to know which piece of hardware had a problem. Update the atomic modeset code to always print the component name along with the type and DRM object ID. Fixes: 4cba6850 ("drm/atomic-helper: Reject legacy flips on a disabled pipe") Fixes: 8d4d0d70 ("drm/atomic-helper: Print an error if vblank wait times out") Fixes: 5481c8fb ("drm/atomic-helper: Check encoder/crtc constraints") Fixes: 99cf4a29 ("drm/atomic: Add current-mode blob to CRTC state") Fixes: cc4ceb48 ("drm: Global atomic state handling") Signed-off-by:

This kills another dereference of connector->state. connector_mask holds all unchanged connectors at least and any changed connectors are already in state anyway. Signed-off-by:

Maarten Lankhorst authored
Add for_each_(old)(new)_(plane,connector,crtc)_in_state iterators to replace the old for_each_xxx_in_state ones. This is useful for >1 flip depth and getting rid of all xxx->state dereferences. This requires extra fixups done when committing a state after duplicating, which in general isn't valid but is used by suspend/resume. To handle these, introduce drm_atomic_helper_commit_duplicated_state which performs those fixups before checking & committing the state. Changes since v1: - Remove nonblock parameter for commit_duplicated_state. Changes since v2: - Use commit_duplicated_state for i915 load detection. - Add WARN_ON(old_state != obj->state) before swapping. Signed-off-by:

With the vblank hooks in struct drm_crtc_funcs, we do not need to maintain the CRTC specific vblank callbacks with struct imx_drm_crtc_helper_funcs any more. By moving the stuff that we currently do in imx_drm_add_crtc(), like of_node setting and drm_crtc_helper_add()/drm_crtc_init_with_planes() invoking, we can kill things like struct imx_drm_crtc, imx_drm_crtc_helper_funcs and related functions completely. Functions ipu_enable_vblank() and ipu_disable_vblank() are moved around without changes, only for saving the forward declarations. Signed-off-by:

It's common to share screens within CI labs, and it's also common for KVM switches to alter the contents of the CEA block but leave the checksum outdated. So in this case, print a debug message instead of an error.

If dsi_connector fails to allocate, the exit path via label 'fail' checks if connector is null, which it always is, so the cleanup that destroys connector is never going to be called. Hence the failure path can be more optimally performed by removing this and just returning ERR_PTR(-ENOMEM). This also removes the need to initialize connector to NULL, and we can also remove ret too.

Core code already makes drm_driver.get_vblank_counter hook optional by letting drm_vblank_no_hw_counter be the default implementation for the function hook. So the drm_vblank_no_hw_counter assignment in the driver code becomes redundant and can be removed now. Signed-off-by:

The vblank is mostly CRTC specific and implemented as part of CRTC driver. Let's keep the vblank hooks struct drm_driver for legacy drivers, and add corresponding hooks in struct drm_crtc_funcs. These hooks take struct drm_crtc pointer as argument, and will be called by core vblank handling code for DRIVER_MODESET drivers. The new hooks get plugged into core by adding wrapper functions for vblank handling code. The .get_vblank_counter hook is effectively optional, as we provide drm_vblank_no_hw_counter() as the default fallback in the wrapper function. Signed-off-by:

This commit adds a TODO list to the GPU driver developer's guide. The content was taken from the DRMJanitors page on the X.Org wiki: https://www.x.org/wiki/DRMJanitors/ The goal is to track a list of refactorings that would be nice to see merged eventually. Sometimes these would be encountered during patch review on the mailing list, and at other times one can come across these while working in a specific area of code. Signed-off-by:
