[PATCH] ppc64: serialize reports of PCI errors

Browse source

07-eeh-report-race.patch

When a PCI slot is isolated, all PCI functions under that slot are affected.
If hese functions have separate device drivers, the EEH isolation event
might be reported multiple times. This patch adds a lock to prevent the
racing of such multiple reports. It also marks every device under the slot
as having experienced an EEH event, so that multiple reports may be
recognized more easily.
