PBDMA is stalled and s/w is expected to execute teardown.
clear_faulted_error: host is asked to clear fault status when no fault has been asserted.
eng_reset: An engine was reset while the PBDMA unit was processing a
channel from a runlist which serves the engine.

Context TSG teardown procedure:
1. Disable scheduling for the engine's runlist via NV_PFIFO_SCHED_DISABLE.
This enables SW to determine whether a context has hung later in the
process: otherwise, ongoing work on the runlist may keep ENG_STATUS from
reaching a steady state.
2. Disable all channels in the TSG being torn down or submit a new runlist
that does not contain the TSG. This is to prevent the TSG from being
rescheduled once scheduling is reenabled in step 6.
3. Initiate a preempt of the engine by writing the bit associated with its
runlist to NV_PFIFO_RUNLIST_PREEMPT. This allows to begin the preempt
process prior to doing the slow register reads needed to determine
whether the context has hit any interrupts or is hung. Do not poll
NV_PFIFO_RUNLIST_PREEMPT for the preempt to complete.
4. Check for interrupts or hangs while waiting for the preempt to complete.
During the pbdma/eng preempt finish polling, any stalling interrupts
relating to runlist must be detected and handled in order for the
preemption to complete.
5. If a reset is needed as determined by step 4:
a. Halt the memory interface for the engine (as per the relevant engine
procedure).
b. Reset the engine via NV_PMC_ENABLE.
c. Take the engine out of reset and reinit the engine (as per
relevant engine procedure)
6. Re-enable scheduling for the engine's runlist via NV_PFIFO_SCHED_ENABLE.

CTX_STATUS_SWITCH: Engine save hasn't started yet, continue to poll
CTX_STATUS_INVALID: The engine context has switched off. The
preemption step for this engine is complete.
CTX_STATUS_VALID or CTX_STATUS_CTXSW_SAVE: check the ID field:
* If ID matches the TSG for the context being torn down, the engine
reset procedure can be performed, or SW can continue
waiting for preempt to finish if id is not being torn down.
* If ID does NOT match, the context isn't running on the engine.
CTX_STATUS_LOAD: check the NEXT_ID field:
* If NEXT_ID matches the TSG of the context being torn down, the engine
is loading the context and reset can be performed
immediately or after a delay to allow the context a chance to load and
be saved off, or sw can continue waiting for preempt to finish if id
is not being torn down.
* If NEXT_ID does not match the TSG ID or CHID then the context is no
longer on the engine.
SW may alternatively wait for the CTX_STATUS to reach INVALID, but this
may take longer if an unrelated context is currently on the engine or
being switched to.
