* drm/msm: Issue queued events when disabling crtcSean Paul2018-06-041-0/+9
| | | | | | | | | | | | | | | | | Ensure that any queued events are issued when disabling the crtc. This avoids timeouts when we come back and wait for dependencies (like the previous frame's flip_done).

* drm/msm: Move implicit sync handling to prepare_fbSean Paul2018-06-042-31/+2
| | | | | | | | | | | | | In preparation for moving to atomic helpers, move the implicit sync fence handling out of atomic commit and into the plane->prepare_fb() hook. While we're at it, de-duplicate the mdp*_prepare_fb functions.

* drm/msm: Don't subclass drm_atomic_state anymoreArchit Taneja2018-06-032-68/+0
| | | | | | | | | | | | | | | | | | | | With the addition of "private_objs" in drm_atomic_state, we no longer need to subclass drm_atomic_state to store state of share resources that don't perfectly fit within planes/crtc/connector state information. We can now save this state within drm_atomic_state itself using the private objects. Remove the infrastructure that allowed subclassing of drm_atomic_state in the driver.

* drm/msm/mdp5: Use the new private_obj stateArchit Taneja2018-06-034-22/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the usage of the subclassed atomic state (mdp5_state) with a private_obj state embedded within drm_atomic_state. The latter method is the preferred approach, since it's simpler to implement and less prone to errors. The new API replaces the older and equivalent mdp5_state usage in the following pattern: - References to "mdp5_kms->state" (i.e, the old/existing state) is replaced with mdp5_get_existing_global_state(). In the atomic_check path, this should be called with the glob_state_lock drm_modeset_lock alredy taken. - References to "mdp5_get_state()" are replaced with mdp5_get_global_state(). This acquires glob_state_lock and uses drm_atomic_get_private_obj_state() to create a new duplicated state. Changes in v3: - Acquire glob_state_lock in mdp5_smp.c - Added to the msm atomic helper patch set Changes in v4: - None Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Sean Paul <seanpaul@chromium.org>
* drm/msm/mdp5: Add global state as a private atomic objectArchit Taneja2018-06-032-0/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are implemented as a part of atomic state by subclassing drm_atomic_state. The preferred approach is to use the drm_private_obj infrastructure available in the atomic core. mdp5_global_state is introduced as a drm atomic private object. The two funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are the two variants that will be used to access mdp5_global_state. This will replace the existing mdp5_state struct (which subclasses drm_atomic_state) and the funcs around it. These will be removed later once we mdp5_global_state is put to use everywhere.

* drm/msm/mdp5: don't pre-reserve LM's if no dual-dsiRob Clark2018-03-191-1/+5
| | | | | | | | | | If there is only a single DSI interface, don't reserve the first two layer-mixers for the dual-DSI use-case. This was causing problems for WB, not being able to assign a LM, on 8x16, which has only two LM's and a single DSI. Signed-off-by: Rob Clark <robdclark@gmail.com>

* drm/msm/mdp5: rework CTL START signal handlingRob Clark2018-03-197-44/+35
| | | | | | | | | | | | | | | | | | | | For DSI cmd-mode and writeback, we need to write the CTL's START register to kick things off, but we only want to do that once both the encoder and the crtc have a chance to write their corresponding flush bits. The difficulty is that when there is a full modeset (ie. encoder state has changed) we want to defer the start until encoder->enable(). But if only plane's have changed, we want to do this from crtc->commit(). The start_mask was a previous attempt to handle this, but it didn't really do the right thing since atomic conversion. Instead track in the crtc state that the start should be deferred, set to try from encoder's (or in future writeback's) atomic_check(). This way the state is part of the atomic state, and rollback can work properly if an atomic test fails. Signed-off-by: Rob Clark <robdclark@gmail.com>
