[PATCHv3,00/10] PCI error handling

Message

Keith Busch Sept. 18, 2018, 11:56 p.m. UTC

This version is reduced in scope from the previous. The more ambitious
handling from the previous version exacerbates other pre-existing
deadlocking issues that are taking some time to fix.

This is mostly a reduced set from v2, but slightly reordered. There is
one prep patch that fixes the bridges pci state when it is initially
saved, and one AER patch that fixes a use-after free.

Keith Busch (10):
  PCI/portdrv: Use subsys_init for service drivers
  PCI/portdrv: Restore pci state on slot reset
  PCI/AER: Take reference on error devices
  PCI/ERR: Use slot reset if available
  PCI/ERR: Handle fatal error recovery
  PCI/ERR: Always use the first downstream port
  PCI/ERR: Simplify broadcast callouts
  PCI/ERR: Report current recovery status for udev
  PCI: Unify device inaccessible
  PCI: Make link active reporting detection generic
