[Qemu-devel] [PATCH v9 00/11] target-arm: mach virt and -cpu host support

[Peter Maydell <peter.maydell@linaro.org>]

This patchset combines the 'virt' machine definition and
-cpu host support patchsets I've posted previous versions
of. I think these are now ready to go in once 1.8 opens
up; review appreciated.

Changes since previous versions:
 * added in -cpu host patchset, since it really only makes
   sense with mach-virt
 * rearranged virt address space a bit to allow space
   for a reasonable sized boot flash device and possible
   PCI window if a PCI controller model ever becomes possible
 * fixed bug where we weren't starting secondary CPUs in
   "PSCI power-down" state (by adding a CPU property which
   lets the board specify that the CPU starts powered down)
   [thanks to Giridhar Maruthy for tracking this down]
 * includes a KVM header update against current mainline
 * includes (previously RFC'd) patch which provides defines
   of some kernel KVM constants we can use even if not CONFIG_KVM
 * put the KVM CPU type into the CPU object rather than having
   a silly 'QOM object type => constant' lookup table
 * put dtb 'compatible' string into CPU object rather than
   having the board model need to know about it
 * abstracted out the "create a scratch vcpu for querying
   for capabilities" code; this is currently only called in
   one place, but the abstraction will be needed for 64 bit
   KVM ARM support

Mostly this is cleanup and streamlining which I noticed
was either possible or necessary in the course of putting
64 bit KVM ARM control on top of this patchset.


The kernel patch to get the PL011 to work is still needed
(Christoffer tells me he's working on getting a proper fix
done for this):
