Hi all,
Last few months ago, VDUSE (vDPA Device in Userspace) [1] has
been merged into Linux kernel as a framework that make it
possible to emulate a vDPA device in userspace. This series
aimed at implementing a VDUSE block backend based on the
qemu-storage-daemon infrastructure.
To support that,
This adds vduse header to linux headers so that the
relevant VDUSE API can be used in subsequent patches.

This implements a VDUSE block backends based on
the libvduse library. We can use it to export the BDSs
for both VM and container (host) usage.
The new command-line syntax is:
$ qemu-storage-daemon \
--blockdev file,node-name=drive0,filename=test.img \
--export vduse-blk,node-name=drive0,i

Specify maximum possible APIC ID assigned for current VM session to KVM
prior to the creation of vCPUs. By this setting, KVM can set up VM-scoped
data structure indexed by the APIC ID, e.g. Posted-Interrupt Descriptor

footprint

Hi; in real hardware an SMMUv3 might be sat in front of any
DMA-capable device. Putting one in front of a PCI bus is common
but not the only use case. Does QEMU's SMMUv3 model handle that,
or is the implementation currently restricted to only handling DMA
from PCI devices?
I ask because for the Re

This patchset adds QEMU support for querying fd-based KVM statistics.
This allows the user to analyze the behavior of the VM without access
to debugfs.
However, instead of adding an ad hoc command, the new QMP entry point
can be extended in the future to more statistics provider than KVM

From: Mark Kanda
Gathering statistics is important for development, for monitoring and
for performance measurement. There are tools such as kvm_stat that do
this and they rely on the _user_ knowing the interesting data points
rather than the tool (which can treat them as opaque).

Add an HMP command to retrieve statistics collected at run-time.
The command will retrieve and print either all VM-level statistics,
or all vCPU-level statistics for the currently selected CPU.

Introduce a simple filtering of statistics, that allows to retrieve
statistics for a subset of the guest vCPUs. This will be used for
example by the HMP monitor, in order to retrieve the statistics

This can be useful when working on a feature or optimization that is

When writing a register from the TCTXT memory region (4th page within
the IC BAR), we were overwriting the Presentation Controller (PC)
register at the same offset. It looks like a silly cut and paste

We were somehow lucky: the TCTXT registers being touched are
