file. If that is not specified, then xm will pass the XAUTHORITY
environment variable back to xend instead. This is not sufficient,
since it is possible that XAUTHORITY is not set at all. This doesn't
cause a problem for most X apps, because xlib will use the fall-back of
$HOME/.Xauthority. But the viewer is started from xend, which almost
certainly doesn't have a reasonable HOME variable.
We fix this by always passing some value for
XAUTHORITY. In order of preference, that value is:
1. Use the value from the config file, if specified.
2. Use the value from the XAUTHORITY env variable, if set.
3. Use $HOME/.Xauthority, if HOME is set.
4. Look up the user's home directory via getpwuid, and append
"/.Xauthority"

dom0. This allows you to bind devices to the backend driver *after*
dom0 has booted. You are no longer required to specify the devices to
hide on the kernel command-line. Using the bind/unbind driver
attributes (see /sys/bus/pci/drivers/pciback), you can specify which
devices that the PCI backend will seize. There are three new driver
attributes in that directory:
slots - lists all of the PCI slots that
the PCI backend will try to seize
new_slot - write the name of a slot here
(in 0000:00:00.0 format) to have the PCI
Backend seize the device in this slot
remove_slot - write the name of a slot here to have
the PCI Backend no longer try to seize a
device in this slot
Note that writing to new_slot/remove_slot does not actually change
whether the PCI Backend is actually bound to the device in that slot or
not. Instead, it tells the PCI backend which slots it should be
interested in. The sysfs attributes "bind" and "unbind" (which are
common to all drivers, not just the PCI Backend) must be used to
actually add or remove a device from the PCI backend driver. Note that
the syntax for specifying a device to bind and unbind is very strict (do
not append a newline).
For Example:
# Add a new slot to the PCI Backend's list
echo -n 0000:01:04.d > /sys/bus/pci/drivers/pciback/new_slot
# Now that the backend is watching for the slot, bind to it
echo -n 0000:01:04.d > /sys/bus/pci/drivers/pciback/bind
# Unbind a PCI network card from its network driver
echo -n 0000:05:02.0 > /sys/bus/pci/drivers/3c905/unbind
# And now bind it to the PCI Backend
echo -n 0000:05:02.0 > /sys/bus/pci/drivers/pciback/new_slot
echo -n 0000:05:02.0 > /sys/bus/pci/drivers/pciback/bind
Unfortunately, Linux makes it possible to remove (unbind) a PCI device
from the PCI backend while that device is attached to a driver domain.
It is also possible to unload the PCI Backend module while a PCI
Frontend is attached. DON'T DO EITHER OF THESE ACTIONS. This patch will
output warnings if you do try and do these. Be aware that while access
to the configuration space of the device has been revoked, the driver
domain can still access the I/O resources of the device as they have not
been revoked (although I *hope* to explore adding support for this
soon). Before unloading the module or unbinding a device, shutdown your
driver domain.
These patches also convert a few function and variable declarations to
static (no sense in polluting the global namespace with local function
names) and rename a few structures in drivers/xen/pciback/pci_stub.c.

occurs in xend. Currently, the parsing is hard-coded; it expects that
the desired number is on the first line. My patch is more robust; it
lets values be retrieved by a label. It also exposes a few functions to
retrieve the current allocation and the target allocation.
By abstracting this a little better, I'll be able to address a few
other issues in subsequent patches. Mostly, this allows for better
error checking and guidance for the user. For example, by exposing
get_dom0_current_alloc(), we can (elsewhere, in a later patch) calculate
how large of a VM could potentially be started. This is useful, as it
lets simple VM-creation GUIs guide the user towards reasonable memory
values for new VMs.

where an interrupt (irq) can be specified in the configuration file
and permission to bind to that interrupt will be given to a driver
domain.
This functionality could be used when trying to give a legacy device
to a driver domain. For example, by specifying the i/o ports and the
interrupt of your serial controller, you can use this patch to put a
serial port in a driver domain. This was discussed briefly on
xen-users in regards to using an external modem in a domU:
http://article.gmane.org/gmane.comp.emulators.xen.devel/20573http://article.gmane.org/gmane.comp.emulators.xen.user/8754
Also adds the ability to specify irqs on the xm command-line when
creating a domain (the following examples show a serial port being
given to a domU):
xm create serial-dd irq=4 ioports=03f8-03ff
or in a flat config-file:
irq = [4]
ioports = ['03f8-03ff']
or in an SXP config file:
(device (irq (irq 4)))
(device (ioports (from '0x03f8')(to '0x03ff')))
The ioports functionality is already in xen, but this patch also fixes a
bug with it that I assume cropped up due to changes in xend since it was
submitted ('dev' doesn't exist in iopif.py, returning 'None' seems to be
the solution).
Also adds some in-line documentation in tools/python/xen/xm/create.py
to be more accurate regarding adding pci devices and i/o ports on the
command-line.
