drm: Check that the plane supports the request format+modifier combo

2018-02-26T14:29:47Z

Currently we only check that the plane supports the pixel format of the fb we're about to feed to it. Extend it to check also the modifier, and more specifically that the combination of the format and modifier is supported.

drm/atomic: Handle 64-bit return from drm_crtc_vblank_count()

2018-02-15T19:49:57Z

570e86963a51 ("drm: Widen vblank count to 64-bits [v3]") changed the return type for drm_crtc_vblank_count() to u64. The flip ioctl receives a 32-bit target sequence from user space and is compared against the current sequence from drm_crtc_vblank_count(). So, typecast return from drm_crtc_vblank_count() explicitly to add clarity. __drm_crtcs_state.last_vblank_count however only ever stores the value from drm_crtc_vblank_count() and can be upgraded to u64.

drm: Warn if plane/crtc/encoder/connector index exceeds our 32bit bitmasks

2018-01-29T16:46:53Z

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 Cc: Maarten Lankhorst Cc: Daniel Vetter Reviewed-by: Maarten Lankhorst Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180125133020.23845-1-ville.syrjala@linux.intel.com Reviewed-by: Harry Wentland

drm/plane: Make framebuffer refcounting the responsibility of setplane_internal callers

2017-12-20T13:49:06Z

lock_all_ctx in setplane_internal may return -EINTR, and __setplane_internal could return -EDEADLK. Making more special cases for fb would make the code even harder to read, so the easiest solution is not taking over the fb refcount, and making callers responsible for dropping the ref.

drm/vblank: Pass crtc_id to page_flip_ioctl.

2017-11-23T12:04:19Z

We added crtc_id to the atomic ioctl, but forgot to add it for vblank and page flip events. Commit bd386e518056 ("drm: Reorganize drm_pending_event to support future event types [v2]") added it to the vblank event, but page flip event was still missing. Correct this and add a test for making sure we always set crtc_id correctly.

drm: Check mode object lease status in all master ioctl paths [v4]

2017-10-25T06:31:30Z

Attempts to modify un-leased objects are rejected with an error. Information returned about unleased objects is modified to make them appear unusable and/or disconnected. Changes for v2 as suggested by Daniel Vetter : * With the change in the __drm_mode_object_find API to pass the file_priv along, we can now centralize most of the lease-based access checks in that function. * A few places skip that API and require in-line checks. Changes for v3 provided by Dave Airlie * remove support for leasing encoders. * add support for leasing planes. Changes for v4 * Only call drm_lease_held if DRIVER_MODESET.
