'tag' is just an abstraction to identify the command
from the driver. So we should make that explicit by
replacing 'tag' with a driver-defined pointer 'hba_private'.
This saves the lookup for driver handling several commands
in parallel.
'tag' is still being kept for tracing purposes.

The original config was making harder to maintain custom config files
with virtio drivers install enabled. So, rather than doing a whitelist
of OSs, just make a not very strict blacklist, just to help users, and

This patch is simple, put in a different commit so it can be more easily
shared between guest and hypervisor. It just defines a named constant

This is per-vcpu, and using the kvmclock structure for that is an abuse

Hi guys,
On an effort to make KVM autotest better and more useful for our target
users (KVM developers), we are expanding documentation and writing
articles on how to get some commonly asked test jobs running (I plan on
get this going at least for some weeks).
So here is our first KVM autotest ti

This patch removes the 8 byte length limit on ioeventfds.
The consequences are that any write in the provided region
which is contained entierly by the region and matches datamatch
(if specified) will trigger an event.

The new flag specifies whether reads from the address specified
in the ioeventfd will raise the event like writes do.
The read value will be the one passed in datamatch.

The new flag allows passing a connected socket instead of an
eventfd to be notified of writes or reads to the specified memory region.
Instead of signaling an event, On write - the value written to the memory
region is written to the pipe.
On read - a notification of the read is sent to the host,
