2018-06-04drm/msm: Fix NULL deref on bind/probe deferralSean Paul
This patch avoids dereferencing msm_host->dev when it is NULL. If we find ourselves tearing down dsi before calling (mdp4|mdp5|dpu)_kms_init(), we'll end up in a state where the dev pointer is NULL and trying to extract priv from it will fail. This was introduced in a seemingly innocuous commit to ensure the arguments to msm_gem_put_iova() are correct (even though that function has been a stub for ~5 years).

2018-06-03drm/msm: Don't subclass drm_atomic_state anymoreArchit Taneja
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.

2018-06-03drm/msm/mdp5: Use the new private_obj stateArchit Taneja
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.

2018-06-03drm/msm/mdp5: Add global state as a private atomic objectArchit Taneja
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.

2018-06-03drm/msm: Fix possible null dereference on failure of get_pages()Ben Hutchings
Commit 62e3a3e342af changed get_pages() to initialise msm_gem_object::pages before trying to initialise msm_gem_object::sgt, so that put_pages() would properly clean up pages in the failure case. However, this means that put_pages() now needs to check that msm_gem_object::sgt is not null before trying to clean it up, and this check was only applied to part of the cleanup code. Move it all into the conditional block. (Strictly speaking we don't need to make the kfree() conditional, but since we can't avoid checking for null ourselves we may as well do so.)

2018-05-31drm/i915: Remove stale asserts from i915_gem_find_active_request()Chris Wilson
Since we use i915_gem_find_active_request() from inside intel_engine_dump() and may call that at any time, we do not guarantee that the engine is paused nor that the signal kthreads and irq handler are suspended, so we cannot assert that the breadcrumb doesn't advance and that the irq hasn't happened on another CPU signaling the request we believe to be idle. The second assert removed (that request->engine == engine) remains valid, but is now more rigorously checked during retirement.

2018-05-31Revert "drm/i915/edp: Allow alternate fixed mode for eDP if available."Jani Nikula
This reverts commit dc911f5bd8aacfcf8aabd5c26c88e04c837a938e. Per the report, no matter what display mode you select with xrandr, the i915 driver will always select the alternate fixed mode. For the reporter this means that the display will always run at 40Hz which is quite annoying. This may be due to the mode comparison. But there are some other potential issues. The choice of alt_fixed_mode seems dubious. It's the first non-preferred mode, but there are no guarantees that the only difference would be refresh rate. Similarly, there may be more than one preferred mode in the probed modes list, and the commit changes the preferred mode selection to choose the last one on the list instead of the first. (Note that the probed modes list is the raw, unfiltered, unsorted list of modes from drm_add_edid_modes(), not the pretty result after a drm_helper_probe_single_connector_modes() call.) Finally, we already have eerily similar code in place to find the downclock mode for DRRS that seems like could be reused here. Back to the drawing board. Note: This is a hand-crafted revert due to conflicts. If it fails to backport, please just try reverting the original commit directly.
