Hi All,
When we moved from the spicevmc device (which directly implemented a virtio
serial port) to doing spicevmc as a chardev backend we lost the notification
of the guest opening / closing the port to spice server. This causes the
server to not fall back to server mouse mode when the agent insi
Some frontends know when the guest has opened the "channel" and is actively
listening to it, for example virtio-serial. This patch adds 2 new qemu-chardev
functions which can be used by frontends to signal guest open / close, and
allows interested backends to listen to this.

On ppc machines with hash table MMUs, the special purpose register SDR1
contains both the base address of the encoded size (hashed) page tables.
At present, we interpret the SDR1 value within the address translation
path. But because the encodings of the size for 32-bit and 64-bit are

This patch adds a "pseries" machine to qemu. This aims to emulate a
logical partition on an IBM pSeries machine, compliant to the
"PowerPC Architecture Platform Requirements" (PAPR) document.
This initial version is quite limited, it implements a basic machine
and PAPR hypercall emulation. So fa
On pSeries logical partitions, excepting the old POWER4-style full system
partitions, the guest does not have direct access to the hardware page
table. Instead, the pagetable exists in hypervisor memory, and the guest
must manipulate it with hypercalls.
However, our current pSeries emulation more
For a 64-bit PowerPC target, qemu correctly implements translation
through the segment lookaside buffer. Likewise it supports the
slbmte instruction which is used to load entries into the SLB.
However, it does not emulate the slbmfee and slbmfev instructions
which read SLB entries back into regis
Traditionally, the "segments" used for the two-stage translation used on
powerpc MMUs were 256MB in size. This was the only option on all hash
page table based 32-bit powerpc cpus, and on the earlier 64-bit hash page
table based cpus. However, newer 64-bit cpus also permit 1TB segments

This adds emulation support for the recent POWER7 cpu to qemu. It's far
from perfect - it's missing a number of POWER7 features so far, including
any support for VSX or decimal floating point instructions. However, it's
close enough to boot a kernel with the POWER7 PVR.

On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations. On logical partitions
under a hypervisor, many of the RTAS functions require hypervisor

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.

This patch adds infrastructure to support interrupts from PAPR virtual IO
devices. This includes correctly advertising those interrupts in the

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.
This patch implements a mechanism for bypassing TCE translation, tre
This patch implements the infrastructure and hypercalls necessary for the

Shared-processor partitions are those where a CPU is time-sliced between
partitions, rather than being permanently dedicated to a single
partition. qemu emulated partitions, since they are just scheduled with
the qemu user process, behave mostly like shared processor partitions.

The slb_lookup() function, used in the ppc translation path returns a
