We added crtc_id to the atomic ioctl, but forgot to add it for vblank and page flip events. Commit bd386e51 ("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.

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 <daniel.vetter@ffwll.ch>: * 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 <airlied@redhat.com> * remove support for leasing encoders. * add support for leasing planes. Changes for v4 * Only call drm_lease_held if DRIVER_MODESET.

Place drm_event_vblank in a new union that includes that and a bare drm_event structure. This will allow new members of that union to be added in the future without changing code related to the existing vbl event type. Assignments to the crtc_id field are now done when the event is allocated, rather than when delievered. This way, delivery doesn't need to have the crtc ID available. v2: * Remove 'dev' argument from create_vblank_event It wasn't being used anyways, and if we need it in the future, we can always get it from crtc->dev. * Check for MODESETTING before looking for crtc in queue_vblank_event UMS drivers will oops if we try to get a crtc, so make sure we're modesetting before we try to find a crtc_id to fill into the event.

The reason behind the original indirection through the helper functions was to allow existing drivers to overwrite how they handle properties. For example when a vendor-specific userspace had expectations that didn't match atomic. That seemed likely, since atomic is standardizing a _lot_ more of the behaviour of a kms driver. But 20 drivers later there's no such need at all. Worse, this forces all drivers to hook up the default behaviour, breaking userspace if they forget to do that. And it forces us to export a bunch of core function just for those helpers. And finally, these helpers are the last places using drm_atomic_legacy_backoff() and the implicit acquire_ctx. This patch here just implements the new behaviour and updates the docs. Follow-up patches will garbage-collect all the dead code. v2: Fixup docs even better! v3: Make it actually work ... v4: Drop the uses_atomic_modeset() checks from the previous patch again, since they're now moved up in the callchain.

Atomic drivers only use the property value store for immutable (i.e. can't be set by userspace, but the kernel can still adjust it) properties. The only tricky part is the removal of the update in drm_atomic_helper_update_legacy_modeset_state(). This was added in commit 8c10342c (tag: topic/drm-misc-2015-07-28) Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Mon Jul 27 13:24:29 2015 +0200 drm/atomic: Update legacy DPMS state during modesets, v3. by copying it from the i915 code, where it was originally added in commit 68d34720 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Sep 6 22:08:35 2012 +0200 drm/i915: update dpms property in set_mode for the legacy modeset code. The reason we needed this hack was that i915 didn't yet set DRIVER_ATOMIC, and we checked for that instead of the newer-ish drm_drv_uses_atomic_modeset(), which avoids such troubles. With the correct feature checks this isn't needed anymore at all. Also make sure that drivers don't accidentally get this wrong by making the exported version of drm_object_property_get_value() only work for legacy drivers.

I failed to properly onion-wrap the unwind code: We acquire the vblank reference before we start with the wait-wound locking dance, hence we must make sure we retry before we drop the reference. Oops. v2: The vblank_put must be after the frambuffer_put (Michel). I suck at unwrapping code that doesn't use separate labels for each stage, but checks each pointer first ... While re-reading everything I also realized that we must clean up the fb refcounts, and specifically plane->old_fb before we drop the locks, either in the final unlocking, or in the w/w retry path. Hence the correct fix is to drop the vblank_put to the very bottom.

These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything.

Rather than compare the format u32s of two format infos, we can direclty compare the format info pointers themselves. Noramlly all the ->format pointers all point to somwehere in the big array, so this is a valid way to test for equality. Also drivers may want to point ->format at a private format info struct instead (eg. for special compressed formats with extra planes), so just comparing the pixel format values wouldn't necessaritly even work.

Replace uses of fb->pixel_format with fb->format->format. Less duplicated information is a good thing.

Encoders&planes can't be hotplugged, we dont need locking for this since it's all single-threaded driver setup/teardown code. CRTCs already don't grab locks. While at it I noticed that plane's are missing the drm_modeset_lock_fini() call, so add it.

There is now a new property called IN_FENCE_FD attached to every plane state that receives sync_file fds from userspace via the atomic commit IOCTL. The fd is then translated to a fence (that may be a fence_array subclass or just a normal fence) and then used by DRM to fence_wait() for all fences in the sync_file to signal. So it only commits when all framebuffers are ready to scanout. v2: Comments by Daniel Vetter: - remove set state->fence = NULL in destroy phase - accept fence -1 as valid and just return 0 - do not call fence_get() - sync_file_fences_get() already calls it - fence_put() if state->fence is already set, in case userspace set the property more than once. v3: WARN_ON if fence is set but state has no FB v4: Comment from Maarten Lankhorst - allow set fence with no related fb v5: rename FENCE_FD to IN_FENCE_FD v6: Comments by Daniel Vetter: - rename plane_state->in_fence back to "fence" - re-introduce WARN_ON if fence set but no fb - rebase after fence -> dma_fence rename v7: Comments by Brian Starkey - set state->fence to NULL when duplicating the state - fail if IN_FENCE_FD was already set v8: rebase against latest drm-misc Signed-off-by: NGustavo Padovan <gustavo.padovan@collabora.co.uk> Reviewed-by: NBrian Starkey <brian.starkey@arm.com> Reviewed-by: NSean Paul <seanpaul@chromium.org> Tested-by: NRobert Foss <robert.foss@collabora.com> [danvet: Rebase onto extracted drm_mode_config.[hc].] Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

The function's behaviour was changed in 90844f00, without changing its signature, causing people to keep using it the old way without realising they were now leaking memory. Rob Clark also noticed it was also allocating GFP_KERNEL memory in atomic contexts, breaking them. Instead of having to allocate GFP_ATOMIC memory and fixing the callers to make them cleanup the memory afterwards, let's change the function's signature by having the caller take care of the memory and passing it to the function. The new parameter is a single-field struct in order to enforce the size of its buffer and help callers to correctly manage their memory.
