This is what remains of yesterday's VFIO groups patchset that is
considered still useful, but wasn't yet ACKed (I've pushed the 5 that
were ACKed). In addition, I found a few more bugs in the
virPCIDeviceList handling and have included patches for those. There
are a couple of these that would be really nice to get into 1.0.7, one
in particular which is new functionality, but has 4 prerequisites:
The most important patch here from a functionality point of view is
PATCH 05/12, which adds the <iommuGroup> element to the output of
"virsh nodedev-dumpxml". This is essential for users/management
applications to have adequate information to know which devices need
to be detached from host drivers. (Unfortunately, all of the patches
prior to 05/12 are required for 05/12 to cleanly apply.)
The other new patch that I've been told is important is 08/12, which
supresses reset of PCI devices that were/will be assigned using VFIO -
apparently the vfio driver already resets the devices when
appropriate, so having libvirt do it is just redundant. (In order for
08/12 to operate reliably, 07/12 is required, and in order for 07/12
to apply, 06/12 must also be applied).
If someone ACKs any of these patches prior to DV cutting the first rc
and I don't respond on IRC (not sure what my schedule is in the next
12 hours :-), please feel free to push any of them you like, as long
as you push them in order with none missing from the middle.
