[Powerpc-utils-devel] [PATCH 0/4] drmgr: PHB unplug fix-ups for QEMU-based PHB hotplug

[Michael R. <md...@li...>]

The following patches address a number of issue that arise when unplugging
PHBs from a QEMU/PowerKVM pSeries guest. Most are due to minor differences
in how PHBs are allocated in QEMU (lots of empty PCI slots) vs. PowerVM
(1 slot per PHB, generally pre-populated with a device).

The last patch is to simplify automation of PHB unplug/hotplug in
rtas_errd, which currently relies on numerical DRC indexes for
PCI/LMB hotplug (patch not yet posted, as it relies on these changes),
as well as for parity with current drmgr functionality with PCI/LMB
command syntax.

QEMU patches for PHB hotplug are available here:

There are still in review, but the powerpc-utils bits are not expected to
change and follow the same format as PCI/LMB.
