Using the QMP GHESv2 API requires preparing a raw data array
containing a CPER record.
Add a helper script with subcommands to prepare such data.
Currently, only ARM Processor error CPER record is supported, by
using:
$ ghes_inject.py arm
which produces those warnings on Linux:
[ 705.032426] [Firmware Warn]: GHES: Unhandled processor error type 0x02: cache error
[ 774.866308] {4}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 1
[ 774.866583] {4}[Hardware Error]: event severity: recoverable
[ 774.866738] {4}[Hardware Error]: Error 0, type: recoverable
[ 774.866889] {4}[Hardware Error]: section_type: ARM processor error

[ 774.867801] {4}[Hardware Error]: error_type: 0x02: cache error
[ 774.867962] {4}[Hardware Error]: error_info: 0x000000000091000f
[ 774.868124] {4}[Hardware Error]: transaction type: Data Access
[ 774.868280] {4}[Hardware Error]: cache error, operation type: Data write
[ 774.868465] {4}[Hardware Error]: cache level: 2
[ 774.868592] {4}[Hardware Error]: processor context not corrupted
[ 774.868774] [Firmware Warn]: GHES: Unhandled processor error type 0x02: cache error
Such script allows customizing the error data, allowing to change
all fields at the record. Please use:
$ ghes_inject.py arm -h
For more details about its usage.
