      XDMA: Mark engine as not running when stopping after timeouts · cf3611e0
      Jessica Clarke authored 
      Unlike engine_start, which sets the engine's running field itself,
engine_stop instead requires its callers to clear the field. However,
not all of them do, and notably the timeout handlers do not, meaning
that after a request times out and we stop the engine we never start it
again, causing all future transfers on the channel to hit the software
timeout.

Instead, set running to 0 inside xdma_engine_stop to mirror engine_start
to both fix the bug and prevent future ones creeping in.

      xdma_thread: fix cpu node bug · 7fc246ee
      Julien authored 
      The number of threads is arbitrarily set to 8 and we iterate over 8 cpus
without knowing if we really have 8 cpus. This causes a call to
cpu_to_node with an index that is out of bound, thus returning an
undefined number, which crashes later when calling
kthread_create_on_node.
Fix this by iterating over the online cpus stopping when reaching the
number of threads that is specified.

      Fixes a design error revealed by running on aarch64. · d1f334b1
      Bryce Hathaway authored 
      Simply put, you cannot call wait_event_interruptible_timeout while
holding a spin_lock. The reason the driver got away with this on
x86 is because the hardware is somehow fast enough so that the
condition is never false and hence no scheduling ever needs to
occur.
