But then I tested it ... I injected a UC error to memory - then did a simple byte write to the target line. This resulted in two banks logging errors:
[ 124.638045] poll: CPU54 saw ec00000000010092 in bank 7 [ 124.639006] poll: severity = 0 [ 124.647333] poll: CPU54 saw b800000000200179 in bank 3 [ 124.648322] poll: severity = 1 The bank 7 error reported as severity 0 because EN=0 ... so we took no action for it. The bank 3 error got past that hurdle, then through the next BIT(8) set indicates a cache error. Fell at the last check because ADDRV=0. I think the severity table entry for the "EN" check should have been skipped when calling from the CMCI handler. Then we would have seen severity=1 from the bank 7 error. It would have passed the other tests too (BIT(7) and ADDRV). -Tony
