Avoid a NULL dereference for a mismatched encoder type, hit when probing state for all encoders. This is a band aid to prevent the OOPS as the right fix is "probably to swap the psr vs infoframes.enable checks, or outright disappear from this function" (Ville).

If the execbuf is interrupted after building the cmdparser pipeline, and before we commit to submitting the request to HW, we would attempt to clean up the cmdparser early. While we held active references to the vma being parsed and constructed, we did not hold an active reference for the buffer pool itself. The result was that an interrupted execbuf could still have run the cmdparser pipeline, but since the buffer pool was idle, its target vma could have been recycled. Note this problem only occurs if the cmdparser is running async due to pipelined waits on busy fences, and the execbuf is interrupted.

Since GM200, SORs are no longer tied to a specific connector, and we allocate them instead, with the assumption that all SORs are equally capable. However, there's a 1<->1 mapping between SOR and HDA pin widget, and it turns out that it's possible for some widgets to be disabled... In order to avoid picking a SOR without a valid pin widget, some new rules need to be added. Signed-off-by: -

[Why] Whenever we switch between tiled formats without also switching pixel formats or doing anything else that recreates the DC plane state we can run into underflow or hangs since we're not updating the DML parameters before committing to the hardware. [How] If the update type is FULL then call validate_bandwidth again to update the DML parmeters before committing the state. This is basically just a workaround and protective measure against update types being added DC where we could run into this issue in the future. We can only fully validate the state in advance before applying it to the hardware if we recreate all the plane and stream states since we can't modify what's currently in use. The next step is to update DM to ensure that we're creating the plane and stream states for whatever could potentially be a full update in DC to pre-emptively recreate the state for DC global validation. The workaround can stay until this has been fixed in DM. Signed-off-by:

While the current locking/serialization of the global state suffices for protecting the obj->state access and the actual hardware reprogramming, we do have a problem with accessing the old/new states during nonblocking commits. The state computation and swap will be protected by the crtc locks, but the commit_tails can finish out of order, thus also causing the atomic states to be cleaned up out of order. This would mean the commit that started first but finished last has had its new state freed as the no-longer-needed old state by the other commit. To fix this let's just refcount the states. obj->state amounts to one reference, and the intel_atomic_state holds extra references to both its new and old global obj states.

With the advent of preempt-to-busy, a request may still be on the GPU as we unwind. And in the case of a unpreemptible [due to HW] request, that request will remain indefinitely on the GPU even though we have returned it back to our submission queue, and cleared the active bit. We only run the execution callbacks on transferring the request from our submission queue to the execution queue, but if this is a bonded request that the HW is waiting for, we will not submit it (as we wait for a fresh execution) even though it is still being executed. As we know that there are always preemption points between requests, we know that only the currently executing request may be still active even though we have cleared the flag. However, we do not precisely know which request is in ELSP[0] due to a delay in processing events, and furthermore we only store the last request in a context in our state tracker.

When we push a virtual request onto the HW, we update the rq->engine to point to the physical engine. A request that is then submitted by the user that waits upon the virtual engine, but along the physical engine in use, will then see that it is due to be submitted to the same engine and take a shortcut (and be queued without waiting for the completion fence). However, the virtual request may be preempted (either by higher priority users, or by timeslicing) and removed from the physical engine to be migrated over to one of its siblings. The dependent normal request however is oblivious to the removal of the virtual request and remains queued to execute on HW, believing that once it reaches the head of its queue all of its predecessors will have completed executing! v2: Beware restriction of signal->execution_mask prior to submission.

In order to be valid to dereference during the i915_fence_release, after retiring the fence and releasing its refererences, we assume that rq->engine can only be a real engine (that stay intact until the device is shutdown after all fences have been flushed). However, due to a quirk of preempt-to-busy, we may retire a request that still belongs to a virtual engine and so eventually free it with rq->engine being invalid. To avoid dereferencing that invalid engine, we look at the execution_mask which if it indicates it may be executed on more than one engine, we know it originated on a virtual engine and may still be on one.

Since the removal of the no-semaphore boosting, we rely on timeslicing to reorder passed inter-dependency hogs across the engines. However, we require preemption to support timeslicing into user payloads, and not all machine support preemption so we do not universally enable timeslicing, even when it would correctly preempt our own inter-engine semaphores. Since timeslicing and semaphore priority deboosting is now disabled on Broadwell/Braswell, we have to follow suite and not use semaphores.
