Add health reporters for RVU NPA block.
NPA Health reporters handle following HW event groups
- GENERAL events
- ERROR events
- RAS events
- RVU event
Output:
#devlink health
pci/0002:01:00.0:
reporter hw_npa_intr
state healthy error 0 recover 0 grace_period 0 auto_recover true
auto_dump true
reporter hw_npa_gen
state healthy error 0 recover 0 grace_period 0 auto_recover true
auto_dump true
reporter hw_npa_err
state healthy error 0 recover 0 grace_period 0 auto_recover true
auto_dump true
reporter hw_npa_ras
state healthy error 0 recover 0 grace_period 0 auto_recover true
auto_dump true
#devlink health dump show pci/0002:01:00.0 reporter hw_npa_err
NPA_AF_ERR:
NPA Error Interrupt Reg : 4096
AQ Doorbell Error
#devlink health dump show pci/0002:01:00.0 reporter hw_npa_ras
NPA_AF_RVU_RAS:
NPA RAS Interrupt Reg : 0
Each reporter dump shows the Register value and the description of the
cause.
