qdev: register all types natively through QEMU Object Model

This was done in a mostly automated fashion. I did it in three steps and then
rebased it into a single step which avoids repeatedly touching every file in
the tree.

The first step was a sed-based addition of the parent type to the subclass...

spapr: convert to QEMU Object Model (v2)

Signed-off-by: Anthony Liguori <>

v1 -> v2
- use QOM to check for the default console

pseries: Populate "/chosen/linux,stdout-path" in the FDT

There is a device tree property "/chosen/linux,stdout-path" which indicates
which device should be used as stdout - ie. "the console".

Currently we don't specify anything, which means both firmware and Linux...

pseries: Remove hcalls callback

For forgotten historical reasons, PAPR hypercalls for specific virtual IO
devices (oh which there are quite a number) are registered via a callback
in the VIOsPAPRDeviceInfo structure.

This is kind of ugly, so this patch instead registers hypercalls from...

pseries: Use Book3S-HV TCE acceleration capabilities

The pseries machine of qemu implements the TCE mechanism used as a
virtual IOMMU for the PAPR defined virtual IO devices. Because the
PAPR spec only defines a small DMA address space, the guest VIO
drivers need to update TCE mappings very frequently - the virtual...

pseries: Refactor spapr irq allocation

Paulo Bonzini changed the original spapr code, which manually assigned irq
numbers for each virtual device, to allocate them automatically from the
device initialization. That allowed spapr virtual devices to be constructed...

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...

spapr: prepare for qdevification of irq

Restructure common properties for sPAPR devices so that IRQ definitions
can be added in one place.

Place pseries vty devices at addresses more similar to existing machines

Currently the qemu pseries machine numbers its virtual serial devices
from 0. However, existing pSeries machines running pHyp number them from
0x30000000.

In theory these indices are arbitrary, since everything necessary for the...

Implement PAPR virtual SCSI interface (ibmvscsi)

This patch implements the infrastructure and hypercalls necessary for
the PAPR specified Virtual SCSI interface. This is the normal method
for providing (virtual) disks to PAPR partitions.

Add a PAPR TCE-bypass mechanism for the pSeries machine

Usually, PAPR virtual IO devices use a virtual IOMMU mechanism, TCEs,
to mediate all DMA transfers. While this is necessary for some sorts of
operation, it can be complex to program and slow for others....

Add PAPR H_VIO_SIGNAL hypercall and infrastructure for VIO interrupts

This patch adds infrastructure to support interrupts from PAPR virtual IO
devices. This includes correctly advertising those interrupts in the
device tree, and implementing the H_VIO_SIGNAL hypercall, used to...

Add (virtual) interrupt to PAPR virtual tty device

Now that we have implemented the PAPR "xics" virtualized interrupt
controller, we can add interrupts in PAPR VIO devices. This patch adds
interrupt support to the PAPR virtual tty/console device.

Implement TCE translation for sPAPR VIO

This patch implements the necessary infrastructure and hypercalls for
sPAPR's TCE (Translation Control Entry) IOMMU mechanism. This is necessary
for all virtual IO devices which do DMA (i.e. nearly all of them).

Implement sPAPR Virtual LAN (ibmveth)

This patch implements the PAPR specified Inter Virtual Machine Logical
LAN; that is the virtual hardware used by the Linux ibmveth driver.

Implement PAPR CRQ hypercalls

This patch implements the infrastructure and hypercalls necessary for the
PAPR specified CRQ (Command Request Queue) mechanism. This general
request queueing system is used by many of the PAPR virtual IO devices,
including the virtual scsi adapter....

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)....
