pseries: SLOF PCI flag day
Currently on the pseries machine the SLOF firmware is used normally,but we bypass it when -kernel is specified. Having these two
different boot paths can cause some confusion.
In particular at present we need to "probe" the (emulated) PCI bus and...

vmstate, memory: decouple vmstate from memory API
Currently creating a memory region automatically registers it forlive migration. This differs from other state (which is enumeratedin a VMStateDescription structure) and ties the live migration codeinto the memory core....
pseries: Populate "/chosen/linux,stdout-path" in the FDT
There is a device tree property "/chosen/linux,stdout-path" which indicateswhich device should be used as stdout - ie. "the console".
Currently we don't specify anything, which means both firmware and Linux...
pseries: FDT NUMA extensions to support multi-node guests
Add NUMA specific properties to guest's device tree to boot a multi-nodeguests. This patch adds the following properties:

pseries: Correct RAM size check for SLOF
The SLOF firmware used on the pseries machine needs a reasonable amount of(guest) RAM in order to run, so we have a check in the machine initfunction to check that this is available. However, SLOF runs in real mode...
pseries: Fix initialization of sPAPREnvironment structure
Since we added PCI support to the pseries machine, we include a qlist ofPCI host bridges in the sPAPREnvironment structure. However this listwas never properly initialized it. Somehow we got away with this until...
pseries: Add partial support for PCI
This patch adds a PCI bus to the pseries machine. This instantiatesthe qemu generic PCI bus code, advertises a PCI host bridge in theguest's device tree and implements the RTAS methods specified by PAPRto access PCI config space. It also sets up the memory regions we...
pseries: Correct vmx/dfp handling in both KVM and TCG cases
Currently, when KVM is enabled, the pseries machine checks if the hostCPU supports VMX, VSX and/or DFP instructions and advertisesaccordingly in the guest device tree. It does this regardless of what...
pseries: Under kvm use guest cpu = host cpu by default
Now that we've implemented -cpu host for ppc, this patch updates thepseries machine to use the host cpu as the guest cpu by default whenrunning under KVM. This is important because under KVM Book3S-HV the guest...
pseries: Support SMT systems for KVM Book3S-HV
Alex Graf has already made qemu support KVM for the pseries machinewhen using the Book3S-PR KVM variant (which runs the guest inusermode, emulating supervisor operations). This code allows gets usvery close to also working with KVM Book3S-HV (using the hypervisor...
pseries: Allow KVM Book3S-HV on PPC970 CPUS
At present, using the hypervisor aware Book3S-HV KVM will only workwith qemu on POWER7 CPUs. PPC970 CPUs also have hypervisorcapability, but they lack the VRMA feature which makes assigning guestmemory easier....
pseries: Add device tree properties for VMX/VSX and DFP under kvm
Sufficiently recent PAPR specifications define properties "ibm,vmx" and "ibm,dfp" on the CPU node which advertise whether the VMX vectorextensions (or the later VSX version) and/or the Decimal Floating...

pseries: Refactor spapr irq allocation
Paulo Bonzini changed the original spapr code, which manually assigned irqnumbers for each virtual device, to allocate them automatically from thedevice initialization. That allowed spapr virtual devices to be constructed...
pseries: use macro for firmware filename
For some time we've had a nicely defined macro with the filename for ourfirmware image. However we didn't actually use it in the place we'resupposed to. This patch fixes it.

pseries: Implement hcall-bulk hypervisor interface
This patch adds support for the H_REMOVE_BULK hypercall on the pseriesmachine. Strictly speaking this isn't necessarym since the kernel willonly attempt to use this if hcall-bulk is advertised in the device tree,...
pseries: interrupt controller should not have a 'reg' property
The interrupt controller presented in the device tree for the pseriesmachine is manipulated by the guest only through hypervisor calls. Ithas no real or emulated registers for the guest to access....
pseries: More complete WIMG validation in H_ENTER code
Currently our implementation of the H_ENTER hypercall, which inserts amapping in the hash page table assumes that only ordinary memory is evermapped, and only permits mapping attribute bits accordingly (WIMG==0010)....
PPC: Enable to use PAPR with PR style KVM
When running PR style KVM, we need to tell the kernel that we wantto run in PAPR mode now. This means that we need to pass some moreregister information down and enable papr mode. We also need to alignthe HTAB to htab_size boundary....
PPC: SPAPR: Use KVM function for time info
One of the things we can't fake on PPC is the timer speed. Sowe need to extract the frequency information from the host andput it back into the guest device tree.
Luckily, we already have functions for that from the non-pseries...
pseries: Add a phandle to the xicp interrupt controller device tree node
Future devices we will be adding to the pseries machine (e.g. PCI) willneed nodes in the device tree which explicitly reference the top-levelinterrupt controller via interrupt-parent or interrupt-map properties....
spapr: proper qdevification
Right now the spapr devices cannot be instantiated with -device,because the IRQs need to be passed to the spapr_*_create functions.Do this instead in the bus's init wrapper.
This is particularly important with the conversion from scsi-disk...

pseries: Increase maximum CPUs to 256
The original pSeries machine was limited to 32 CPUs, more or lessarbitrarily. Particularly when we get SMT KVM guests it will bepretty easy to exceed this. Therefore, raise the max number of CPUsin a pseries machine guest to 256....
Make pSeries 'model' property more closely resemble real hardware
Currently, the qemu emulated pseries machine puts"qemu,emulated-pSeries-LPAR" in the device tree's root level 'model'property. Unfortunately this confuses some installers and ybin, which...
Place pseries vty devices at addresses more similar to existing machines
Currently the qemu pseries machine numbers its virtual serial devicesfrom 0. However, existing pSeries machines running pHyp number them from0x30000000.
In theory these indices are arbitrary, since everything necessary for the...
pseries: Abolish envs array
Currently the pseries machine init code builds up an array, envs, ofCPUState pointers for all the cpus in the system. This is kind ofpointless, given the generic code already has a perfectly good linked listof the cpus.
In addition, there are a number of places which assume that the cpu's...
Delay creation of pseries device tree until reset
At present, the 'pseries' machine creates a flattened device tree in themachine->init function to pass to either the guest kernel or to firmware.
However, the machine->init function runs before processing of -device...
