[Skiboot] [PATCH 3/3] ipmi/wdt: Add ipmi watchdog timer support

Hi Ben,

The downside here is that we'd then have a periodic IPMI transaction,
which may introduce jitter. I'd prefer to leave it up to the OS to
enable - there's the IPMI watchdog in the kernel, which is capable of
handling this.

The downside is that the watchdog won't "watch" the period between OPAL
platform init (where we handle the first interrupt) and watchdog driver
init, but I think that's a reasonable compromise.

Cheers,


Jeremy
