ECC memory of BMC

[Will Liang (梁永鉉)]

Hi Andrew,


Thanks for your response.


We have also found EDAC driver.

What we want to do is to record the ECC events to SEL.


we are considering to create new dbus and a service.


Do you have any suggestions?


BRs,

Will

Well, for what it's worth a kernel driver has been submitted upstream and is
queued for the 5.1 merge window:

https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/commit/?h=for-next&id=9b7e6242ee4efcd7f9ef699bf1965e3a5343f216

The patch does say it needs bootloader support though, and I'm not exactly
sure what that involves. I've added Stefan to Cc, maybe he can provide some
insight.
