+Configurable sysfs parameters for the x86-64 machine check code
+===============================================================
Machine checks report internal hardware error conditions detected
by the CPU. Uncorrected errors typically cause a machine check
from /dev/mcelog. Normally mcelog should be run regularly from a cronjob.
Each CPU has a directory in /sys/devices/system/machinecheck/machinecheckN
-(N = CPU number)
+(N = CPU number).
The directory contains some configurable entries:
-Entries:
-
bankNctl
-(N bank number)
+ (N bank number)
+
64bit Hex bitmask enabling/disabling specific subevents for bank N
When a bit in the bitmask is zero then the respective
subevent will not be reported.
