Linas Vepstas 25c4a46f0e [POWERPC] pSeries: EEH improperly enabled for some Power4 systems ... It appears that EEH is improperly enabled for some Power4 systems. On these systems, the ibm,set-eeh-option returns a value of success even when EEH is not supported on the given node. Thus, an explicit check for support is required. During boot, on power4, without this patch, one sees messages similar to: EEH: event on unsupported device, rc=0 dn=/pci@400000000110/IBM,sp@1 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2 EEH: event on unsupported device, rc=0 dn=/pci@400000000110/pci@2,2 etc. The patch makes these go away. Without this patch, EEH recovery does seem to work correctly for at least some devices (I tested ethernet e1000), but fails to recover others (the Emulex LightPulse LPFC, most notably). Off the top of my head, I don't remember why some devices are affected, but not others. The PAPR indicates that the correct way to test for EEH is as done in this patch; its not clear to me if this was in the PAPR all along, or recently added; if it was there all along, its not clear to me why this hadn't been fixed long ago. I suspect only certain firmware levels are affected. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>		18 years ago
