Subject: [PATCH 00/16] PCI, error handling and hot plug
Date: Fri, 31 Aug 2018 15:26:23 -0600 [thread overview]
Message-ID: <20180831212639.10196-1-keith.busch@intel.com> (raw)
This series is all about error handling and hot plug. It should get the
AER fatal handling much like how it was before where we don't always
tear down and re-enumerate the topology, but even better in taht it
won't trigger hotplug events to the extent possibe to suppress link
events that occur from the secondary bus reset.
Ports that do not implement an out-of-band presence detection mechanism
may still have their device removed on the DPC and AER error handling,
but at least error handling for non-hot pluggable ports won't experience
removals anymore.
Some of these are simple bug fixes, some are more complicated. Patch
11 fixes a long-standing issue where a RP detected fatal error never
restored the downstream bridges, making recovery of end devices below
those switches bound to fail after a secondary bus reset resets the
bridge's config memory and bus windows.
Comments welcomed!
Keith Busch (15):
PCI: Fix pci_reset_bus
PCI/AER: Remove dead code
PCI/ERR: Use slot reset if available
PCI/ERR: Handle fatal error recovery
PCI/ERR: Remove devices on recovery failure
PCI/ERR: Always use the first downstream port
PCI/ERR: Simplify broadcast callouts
PCI/ERR: Report current recovery status for udev
PCI/portdrv: Provide pci error callbacks
PCI/portdrv: Restore pci state on slot reset
PCI/pciehp: Fix powerfault detection order
PCI/pciehp: Implement error handling callbacks
PCI/pciehp: Ignore link events during DPC event
PCI/DPC: Wait for reset complete
PCI: Unify device inaccessible
