Subject: [PATCH] docs: update description of virsh nodedev-detach --driver
option
--driver can now be used to specify a specific driver to bind to the
device being detached from the host driver (e.g. vfio-pci-igbvf), not
just the *type* of driver (e.g. "vfio" or "xen", which are unnecessary
anyway, since they are implicit in which hypervisor driver is in use)

Subject: [PATCH] node_device: support binding other drivers with
virNodeDeviceDetachFlags()
In the past, the only allowable values for the "driver" field of
virNodeDeviceDetachFlags() were "kvm" or "vfio" for the QEMU driver,
and "xen" for the libxl driver. Then "kvm" was deprecated and removed,
so the driver name became essentially irrelevant (because it is always
called via a particular hypervisor driver, and so the "xen" or "vfio"
can be (and almost always is) implied.
With the advent of VFIO variant drivers, the ability to explicitly
specify a driver name once again becomes useful - it can be used to
name the exact VFIO driver that we want bound to the device in place
of vfio-pci, so this patch allows those other names to be passed down
the call chain, where the code in virpci.c can make use of them.
The names "vfio", "kvm", and "xen" retain their special meaning, though:
1) because there may be some application or configuration that still
calls virNodeDeviceDetachFlags() with driverName="vfio", this
single value is substituted with the synonym of NULL, which means
"bind the default driver for this device and hypervisor". This
will currently result in the vfio-pci driver being bound to the
device.
2) in the case of the libxl driver, "xen" means to use the standard
driver used in the case of Xen ("pciback").
3) "kvm" as a driver name always results in an error, as legacy KVM
device assignment was removed from the kernel around 10 years ago.

Subject: [PATCH] util: permit existing binding to VFIO variant driver
Before a PCI device can be assigned to a guest with VFIO, that device
must be bound to the vfio-pci driver rather than to the device's
normal host driver. The vfio-pci driver provides APIs that permit QEMU
to perform all the necessary operations to make the device accessible
to the guest.
In the past vfio-pci was the only driver that supplied these APIs, but
there are now vendor/device-specific "VFIO variant" drivers that
provide the basic vfio-pci driver functionality/API while adding
support for device-specific operations (for example these
device-specific drivers may support live migration of certain
devices). All that is needed to make this functionality available is
to bind the vendor-specific "VFIO variant" driver to the device
(rather than the generic vfio-pci driver, which will continue to work,
just without the extra functionality).
But until now libvirt has required that all PCI devices being assigned
to a guest with VFIO specifically have the "vfio-pci" driver bound to
the device. So even if the user manually binds a shiny new
vendor-specific VFIO variant driver to the device (and puts
"managed='no'" in the config to prevent libvirt from changing the
binding), libvirt will just fail during startup of the guest (or
during hotplug) because the driver bound to the device isn't exactly
"vfio-pci".
Beginning with kernel 6.1, it's possible to determine from the sysfs
directory for a device whether the currently-bound driver is the
vfio-pci driver or a VFIO variant - the device directory will have a
subdirectory called "vfio-dev". We can use that to appropriately widen
the list of drivers that libvirt will allow for VFIO device
assignment.
This patch doesn't remove the explicit check for the exact "vfio-pci"
driver (since that would cause systems with pre-6.1 kernels to behave
incorrectly), but adds an additional check for the vfio-dev directory,
so that any VFIO variant driver is acceptable for libvirt to continue
setting up for VFIO device assignment.

Subject: [PATCH] util: probe stub driver from within function that binds to
stub driver
virPCIProbeStubDriver() and virPCIDeviceBindToStub() both have
very similar code that locally sets a driver name (based on
stubDriverType). These two functions are each also called in just one
place (virPCIDeviceDetach()), with just a small bit of validation code
in between.
To eliminate the "duplicated" code (which is going to be expanded
slightly in upcoming patches to support manually or automatically
picking a VFIO variant driver), this patch modifies
virPCIProbeStubDriver() to take the driver name as an argument
(rather than the virPCIDevice object), and calls it from within
virPCIDeviceBindToStub() (rather than from that function's caller),
using the driverName it has just figured out with the
now-not-duplicated code.
(NB: Since it could be used to probe *any* driver module, the name is
changed to virPCIProbeDriver()).

Subject: [PATCH] util: rename virPCIDeviceGetDriverPathAndName
Instead, call it virPCIDeviceGetCurrentDriverPathAndName() to avoid
confusion with the device name that is stored in the virPCIDevice
object - that one is not necessarily the name of the current driver
for the device, but could instead be the driver that we want to be
bound to the device in the future.

Subject: [PATCH] util: use "stubDriverType" instead of just "stubDriver"
In the past we just kept track of the type of the "stub driver" (the
driver that is bound to a device in order to assign it to a
guest). The next commit will add a stubDriverName to go along with
type, so lets use stubDriverType for the existing enum to make it
easier to keep track of whether we're talking about the name or the
type.
