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 pci/0000:b1:00.3: 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 last_dump_time 09:29:29 auto_dump true $ devlink health diagnose pci/0000:b1:00.3 reporter port Syndrome: 262 Description: Module is not present.
