Hi Iwona,
I've done some testing of these patches on my AST2500/E-2778G OpenBMC
platform -- I had to do a small bit of hacking to add support for
INTEL_FAM6_KABYLAKE, but with that in place the newly-added code for the
8.8 format seems to work as it should. Thanks!
In poking at it a bit further I encountered some sub-optimal behavior
w.r.t. to host power state transitions and timeouts though --
essentially, if I ever hit a timeout in aspeed_peci_xfer() (for example
on a read of a hwmon tempX_input file after an unexpected host
shutdown), it seems to get stuck in a state where even if the host comes
back online, all attempted PECI transfers continue just timing out.
(Rebooting the BMC seems to resolve the problem.) This also happens if
I remove the peci client device via the 'remove' sysfs file, shut down
the host, and then do a rescan via sysfs while the host is off (i.e.
another operation that times out).
Let me know if there's any other info that would be helpful for
debugging.
Thanks,
Zev
