Btw, here's how the rough MCE TP trace_mce_record() looks like:
mcegen.py-2715 [001] .N.. 1049.818840: mce_record: [Hardware Error]: CPU:0 MC4_STATUS[Over|UE|-|PCC|AddrV|UECC]: 0xf604a00006080a41
[Hardware Error]: MC4_ADDR: 0xbabedeaddeadbeef
[Hardware Error]: Northbridge Error (node 0): DRAM ECC error detected
(CPU: 0, MCGc/s: 0/0, MC4: f604a00006080a41, ADDR/MISC: babedeaddeadbeef/dead57ac1ba0babe, RIP: 00:<0000000000000000>, TSC: 0, PROCESSOR: 0:0, TIME: 0, SOCKET: 0, APIC: 0)
Basically, the userspace daemon will consume the error string (after
it's been massaged into looking prettier and smaller :-)) (1st arg)
and dump it to some logs, and use some of the MCE fields to do error
collection and thresholding/ratelimiting/whatever.
While at it, I'm also looking very critically at the fields SOCKET,
APIC, TSC (we have walltime) for I'd like to drop them. Also, MC4 should
be MC4_STATUS btw.
To be continued...
