                 APEI output format
                 ~~~~~~~~~~~~~~~~~~

APEI uses printk as hardware error reporting interface, the output
format is as follow.

Where, [] designate corresponding content is optional

All description with * has the following format:

field: ,

Where value of should be the position of “string” in description. Otherwise, will be “unknown”.

All description with # has the following format:

field:

Where each string in corresponding to one set bit of
. The bit position is the position of “string” in description.

specification version 2.3 or later, section Appendix N: Common
Platform Error Record.
