| |
Please condider the following patch for inclusion. This patch contains implementations of the PCI Hotplug and I/O Slot DLPAR Drivers for PPC64 RISC Platform Architecture. The patch is made against kernel version 2.6.3-rc2.
The PCI Hotplug module allows the runtime addition/removal of I/O adapters on a PPC64 machine. Due to firmware restrictions, hotplug operations must be initiated by userspace tools. These operations are initiated using interface files located at: /sys/bus/pci/pci_hotplug_slots/<bus_name> Development contact for this module is Linda Xie (lxie@us.ibm.com).
The Dynamic Logical Partitioning Module allows the runtime movement of I/O Slots between logical partitions. An administrator can logically add/remove PCI Buses to/from a PPC64 partition at runtime. These operations are initiated using interface files located at: /sys/bus/pci/pci_hotplug_slots/control/ Development contact for this module is John Rose (johnrose@austin.ibm.com).
Due to the size of the patch (~1730 LOC), I have posted it at: http://www-124.ibm.com/linux/patches/misc/ppc64-pci_hotplug-dlpar_drivers-2.6.3-rc2.patch
