Adding Machine Check Exception Logging support to the Linux kernel
In my previous post, I mentioned how the mcelog utility can be used to detect hardware problems. Mcelog relies on the /dev/mcelog device being present, which requires the kernel to be built with the following options:
CONFIG_X86_MCE=y
CONFIG_X86_MCE_INTEL=y
CONFIG_X86_MCE_AMD=y
CONFIG_X86_MCE_THRESHOLD=y
To enable these, you can select the following options once you run ‘make menuconfig’:
[*] Machine Check Exception
│ │ [*] Intel MCE features
│ │ [*] AMD MCE features
