[Qemu-ppc] [PATCH v6 00/10] ppc/pnv: reworking the interrupt controller

[Cédric Le Goater]

Hello,

Here is a short serie adding support for the MMIO based Interrupt
Presentation Controllers (ICP) as found on a POWER8 system. 

The initial patches are mostly cleanups and small extensions to the
XICS framework. They provide a basic container XICS object that the
PowerNV machine can use to hold the ICSs and ICPs of the system. Last
is the PSI HB model which handles the external interrupt.


The next step should be IPMI support which adds a BT device on the ISA
bus and some device tree extensions to read sensors and FRUs. This is
relatively straight forward and most of the IPMI code has been
discussed already on the list. Then should come a PHB3 model to
include some PCI devices. This is big and it needs a few helpers in
the PCI core.

If you feel adventurous, you can grab kernel and rootfs images :

and give it a try. The full patchset is available here :

This is a wip branch.

Thanks,

C.
