The FMA team would like to have an interface to disable
fast reboot on panic in case of terminal machine check error:
================================================================
Subject: Re: Fast Boot & FMA
Hi,
I discussed this with Scott Davenport and Joe Erwin last week.
As part of our co-ordinated host/SP diagnosis efforts we
should be making some suggestions here. I believe the
intention will be to avoid fast boot for any panic
resulting from a terminal machine check exception,
so that firmware can see the register state at reset and
perform diagnosis there, too. We will avoid clearing
registers as we read out the data, so leaving it all there
for firmware to see. We'd need an appropriate hook
to call during panic flow to request a full reset rather
than fast boot - not sure if that already exists today?
Cheers
Gavin
