This patchset adds trace event support for FW-First Protocol Errors. Reworked the patchset to reuse the work item written by Ira for handling CPER events. I understand this patchset also schedules the cxl_pci driver to look at potentially "non-device" errors as Terry's port error handling patches are under review. However, I'm also fine to just confine it until FMLD as of now. Looking for feedbacks here.
