remoteproc: create a 'recovery' debugfs entry
Add a 'recovery' debugfs entry to dynamically disable/enable recovery
at runtime. This is useful when one is trying to debug an rproc crash;
without it, a recovery will immediately take place, making it harder
to debug the crash.
Contributions from Subramaniam Chanderashekarapuram.
Examples:
- disabling recovery:
$ echo disabled > <debugfs>/remoteproc/remoteproc0/recovery
- in case you want to recover a crash, but keep recovery disabled
(useful in debugging sessions when you expect additional crashes
you want to debug):
$ echo recover > <debugfs>/remoteproc/remoteproc0/recovery
- enabling recovery:
$ echo enabled > <debugfs>/remoteproc/remoteproc0/recovery
