[PATCH 0/4] powerpc/powernv: PCI Surprise Hotplug Support

This series of patches supports PCI surprise hotplug on PowerNV platform. Without the corresponding skiboot patches, this feature won't be enabled and workable. * The skiboot patches can be found in below link (PATCH[01/16): https://patchwork.ozlabs.org/project/skiboot/list/?submitter=6392

[PATCH 1/4] powerpc/eeh: Allow to freeze PE in eeh_pe_set_option()

Function eeh_pe_set_option() is used to apply the requested options (enable, disable, unfreeze) in EEH virtualization path. The semantics of this function isn't complete until freezing is supported. This allows to freeze the indicated PE. The new semantics is going to be used in PCI surprise hot r

[PATCH 3/4] powerpc/powernv: Unfreeze PE on allocation

This unfreezes PE when it's initialized because the PE might be put into frozen state in the last hot remove path. It's not harmful to do so if the PE is already in unfrozen state. Signed-off-by: Gavin Shan --- arch/powerpc/platforms/powernv/pci-ioda.c | 12 1 file changed, 12 inser

[Patch V6 0/8] powerpc/devtree: Add support for 2 new DRC properties
