Firmware generates events for global events or port specific events.
Driver shall subscribe for health status events from firmware on supported
FW versions >= 1.7.6.
Driver shall expose those under specific health reporter, two new
reporters are introduced:
- FW health reporter shall represent global events (problems with the
image, recovery mode);
- Port health reporter shall represent port-specific events (module
failure).
Firmware only reports problems when those are detected, it does not store
active fault list.
Driver will hold only last global and last port-specific event.
Driver will report all events via devlink health report,
so in case of multiple events of the same source they can be reviewed
using devlink autodump feature.
$ devlink health

reporter fw
state healthy error 0 recover 0 auto_dump true
reporter port
state error error 1 recover 0 last_dump_date 2024-03-17

$ devlink health diagnose pci/0000:b1:00.3 reporter port
Syndrome: 262
Description: Module is not present.
Possible Solution: Check that the module is inserted correctly.
Port Number: 0
