Suggested by Alex Williamson.
If you plan to assign a GPU to a virtual machine, but that GPU happens
to be the host system console, you likely want it to start out using
the host driver (so that boot messages/etc will be displayed), then
later have the host driver replaced with vfio-pci for assignment to
the virtual machine.
However, in at least some cases (e.g. Intel i915) once the device has
been detached from the host driver and attached to vfio-pci, attempts
to reattach to the host driver only lead to "grief" (ask Alex for
details). This means that simply using "managed='yes'" in libvirt
won't work.
And if you set "managed='no'" in libvirt then either you have to
manually run virsh nodedev-detach prior to the first start of the
guest, or you have to have a management application intelligent enough
to know that it should detach from the host driver, but never reattach
to it.
This patch makes it simple/automatic to deal with such a case - it
adds a third "managed" mode for assigned PCI devices, called
"detach". It will detach ("unbind" in driver parlance) the device
from
the host driver prior to assigning it to the guest, but when the guest
is finished with the device, will leave it bound to vfio-pci. This
allows re-using the device for another guest, without requiring
initial out-of-band intervention to unbind the host driver.
---
I'm sending this with the "RFC" tag because I'm concerned it might be
considered "feature creep" by some (although I think it makes at least
as much sense as "managed='yes'") and also because, even once (if) it
is ACKed, I wouldn't want to push it until abologna is finished
hacking around with the driver bind/unbind code - he has enough grief
to deal with without me causing a bunch of merge conflicts :-)
