Hi Folks :
I am trying to write a virtio driver and towards this end I am looking at
the qemu code. I am a little confused about a few things. Unfortunately,
the few comments in the code does not make it clear for me. So I am
wondering if any kind person on this mailing list would be able to help.

We generally have BDF granularity for devices, so we just need
to make sure devices aren't hidden behind PCIe-to-PCI bridges.
We can then make up a group number that's simply the concatenated
seg|bus|dev|fn so we don't have to track them (not that users
should depend on that).

An IOMMU group is a set of devices for which the IOMMU cannot
distinguish transactions. For PCI devices, a group often occurs
when a PCI bridge is involved. Transactions from any device
behind the bridge appear to be sourced from the bridge itself.
We leave it to the IOMMU driver to define the gr
Trying to move beyond talking about how VFIO should work to
re-writing the code. This is pre-alpha, known broken, will
probably crash your system but it illustrates some of how
I see groups, devices, and iommus interacting. This is just
the framework, no code to actually support user space driver

Several info commands rely on the 'mon_cpu' field in the Monitor

Sometimes, when having lots of VMs running on a RHEV host and the user
attempts to close a SPICE window, libvirt will get corrupted json from
QEMU.
After some investigation, I found out that the problem is that different

I had asked this question a year ago and I managed to have a temporary work
around for doing a single 64bit read/write operations but now I'm looking for a
more complete solution.
Is there anyway we can prevent Qemu breaking up 64,128 and 256bit XMM or YMM
instructions into smaller chunks and h
