This is rework of in-kernel XICS on top of [PATCH 00/11] pseries: migration
and QOM support + compile fix patch + XICS migration fix patch.
Migration from XICS to XICS-KVM and vice versa works.
In this series, XICS-KVM inherits from XICS. I do not really see the point of
adding one more
From: David Gibson da...@gibson.dropbear.id.au
Recent PowerKVM allows the kernel to intercept some RTAS calls from the
guest directly. This is used to implement the more efficient in-kernel
XICS for example. qemu is still responsible for assigning the RTAS token
numbers however, and needs to
The upcoming support of in-kernel XICS will redefine migration callbacks
for both ICS and ICP so classes and callback pointers are added.
This adds a cpu_setup callback to the XICS device class (as XICS-KVM
will do it different) and xics_dispatch_cpu_setup(). This also moves
the place where
Currently RTAS and hypercalls are registered in the XICS class init
function. The upcoming XICS-KVM will inherit from XICS but will use
another API to register RTAS tokens with KVM so registration has
to move from the class init function (common for both XICS and
XICS-KVM) to the _realize function
From: David Gibson da...@gibson.dropbear.id.au
Recent (host) kernels support emulating the PAPR defined XICS interrupt
controller system within KVM. This patch allows qemu to initialize and
configure the in-kernel XICS, and keep its state in sync with qemu's XICS
state as necessary.

With this patch QEMU handles qAttached request from gdb. When QEMU
replies 1, GDB sends a detach command at the end of a debugging

The default value for qAttached is 1 on system emulation and 0 on user

Change -numa option like following as Paolo suggested:
-numa node,nodeid=0,cpus=0-1 \
-numa mem,nodeid=0,size=1G
This new option will make later coming memory hotplug better.
And this new option is implemented using OptsVisitor.
