pseries: Return the token when we register an RTAS call

The kernel will soon be able to service some RTAS calls. However the
choice of tokens will still be up to userspace. To support this have
spapr_rtas_register() return the token that is allocated for an...

spapr: Pass PowerPCCPU to hypercalls

Needed for changing cpu_has_work() argument type to CPUState,
used in h_cede().

pseries: Implement qemu initiated shutdowns using EPOW events

At present, using 'system_powerdown' from the monitor or otherwise
instructing qemu to (cleanly) shut down a pseries guest will not work,
because we did not have a method of signalling the shutdown request to the...

pseries: Remove XICS irq type enum type

Currently the XICS interrupt controller emulation uses a custom enum to
specify whether a given interrupt is level-sensitive or message-triggered.
This enum makes life awkward for saving the state, and isn't particularly...

pseries: Add support for new KVM hash table control call

This adds support for then new "reset htab" ioctl which allows qemu
to properly cleanup the MMU hash table when the guest is reset. With
the corresponding kernel support, reset of a guest now works properly....

pseries: Rework irq assignment to avoid carrying qemu_irqs around

Currently, the interfaces in the pseries machine code for assignment
and setup of interrupts pass around qemu_irq objects. That was done
in an attempt not to be too closely linked to the specific XICS...

pseries dma: DMA window params added to PHB and DT population changed

Previously the only PCI bus supported was the emulated PCI bus with
fixed DMA window with start at 0 and size 1GB. As we are going to support
PCI pass through which DMA window properties are set by the host...

pseries: Implement IOMMU and DMA for PAPR PCI devices

Currently the pseries machine emulation does not support DMA for emulated
PCI devices, because the PAPR spec always requires a (guest visible,
paravirtualized) IOMMU which was not implemented. Now that we have...

spapr: Add "memop" hypercall

This adds a qemu-specific hypervisor call to the pseries machine
which allows to do what amounts to memmove, memcpy and xor over
regions of physical memory such as the framebuffer.

This is the simplest way to get usable framebuffer speed from...

pseries: Add support for level interrupts to XICS

The pseries "xics" interrupt controller, like most interrupt
controllers can support both message (i.e. edge sensitive) interrupts
and level sensitive interrupts, but it needs to know which are which.

When I implemented the xics emulation for qemu, the only devices we...

pseries: FDT NUMA extensions to support multi-node guests

Add NUMA specific properties to guest's device tree to boot a multi-node
guests. This patch adds the following properties:

ibm,associativity
ibm,architecture-vec-5
ibm,associativity-reference-points...

pseries: Add partial support for PCI

This patch adds a PCI bus to the pseries machine. This instantiates
the qemu generic PCI bus code, advertises a PCI host bridge in the
guest's device tree and implements the RTAS methods specified by PAPR
to access PCI config space. It also sets up the memory regions we...

pseries: Implement set-time-of-day RTAS function

Currently there is no implementation for set-time-of-day rtas function,
which causes the following warning "setting the clock failed (-1)" on
the guest.

This patch just creates this function, get the timedate diff and store in...

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...

Delay creation of pseries device tree until reset

At present, the 'pseries' machine creates a flattened device tree in the
machine->init function to pass to either the guest kernel or to firmware.

However, the machine->init function runs before processing of -device...

Implement the PAPR (pSeries) virtualized interrupt controller (xics)

PAPR defines an interrupt control architecture which is logically divided
into ICS (Interrupt Control Presentation, each unit is responsible for
presenting interrupts to a particular "interrupt server", i.e. CPU) and...

Implement the bus structure for PAPR virtual IO

This extends the "pseries" (PAPR) machine to include a virtual IO bus
supporting the PAPR defined hypercall based virtual IO mechanisms.

So far only one VIO device is provided, the vty / vterm, providing
a full console (polled only, for now)....
