Currently, my HP server that I use to build the Kernel is FF:
[ 3.783803] GHES: APEI firmware first mode is enabled by APEI bit and WHEA
_OSC.
I didn't try to disable FF on its BIOS. Not sure if it is even possible.
Still, EDAC is working there using sb_edac. As I pointed before, one of the
MC channels is not being detected, but I don't use it on this machine.
Except for that, EDAC seems to be working fine there:
$ ras-mc-ctl --layout

I didn't try to inject an error, as I'm not sure if EINJ feature is
enabled on this BIOS. Probably not.
At least on this machine, I very much prefer to use sb_edac driver.
As I explained earlier in the previous thread, I just don't if the
BIOS would be doing the right thing for CE, as I don't know its
internal algorithm.
Also, as I'm maintaining the EDAC userspace tools (rasdaemon),
I would really love to get a few CE error reports there from time to
time, as it could be used to check if rasdaemon is doing do the right
thing to them.
So, I very much prefer to not have any threshold at all there at BIOS.
Thanks,
Mauro
