When Firmware First is enabled, BIOS handles errors first and then it makes them available to the kernel via the Common Platform Error Record (CPER) sections (UEFI 2.11 Appendix N.2.13). Linux parses the CPER sections via one of two similar paths, either ELOG or GHES. The errors managed by ELOG are signaled to the BIOS by the I/O Machine Check Architecture (I/O MCA). Currently, ELOG and GHES show some inconsistencies in how they report to userspace via trace events. Therefore, make the two mentioned paths act similarly by tracing the CPER CXL Protocol Error Section.
