The attached patch cleans up the parsing of /proc/xen/balloon that
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.

Adds a new device interface to xend/xm similar to the one for ioports
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/20573
http://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.

Consolidate xc_ptrace and xc_ptrace_core
* xc_ptrace
- Merge xc_ptrace_core into xc_ptrace
- ATTACH now reads the data argument. If non-zero then
a corefile is being debuged. Otherwise a thread has
been attached to. This allows xc_waitdomain_core() or
xc_waitdomain() to be called as appropriate in
subsequent xc_ptrace() calls.
* xc_waitdomain
- Rename xc_waitdomain (xc_ptrace.c version) __xc_waitdomain
- Rename xc_waitdomain (xc_ptrace_core.c version) xc_waitdomain_core
- Create xc_waitdomain (in xc_ptrace.c), a wrapper for __xc_waitdomain
and xc_waitdomain_core.
Consolidation seemed difficult but ctxt needs to be
passed into xc_waitdomain_core or made global.
Alternatively, xc_waitdomain_core could be moved into xc_ptrace.c,
but this seems messy.
* map_domain_va
- Rename map_domain_va (xc_ptrace_core.c version) map_domain_va_core
- Have it accept ctxt, like xc_waitdomain_core
* myptrace and myxcwait (linux-xen-low.c)
Removed, call the now generic xc_ptrace() and xc_waitdomain() instead
When calling xc_ptrace ATTACH, if a corefile is in use, a fd will
be passed, otherwise a pid. The fd part is important, as this
is saved internally in xc_ptrace_core.c, and passed to xc_waitdomain_core()
as neccessary. Pereviously xc_waitdomain_core() received a pid and
thus could not open the corefile.

libxc: xc_ptrace cleanups
General Cleanups
* Use { after if consistently in xc_ptrace.c and xc_ptrace_core.c
(But not in xc_ptrace_core() which should be removed shortly)
* Remove duplicate code and centralise around xc_ptrace.h
* Avoid ifing values covered by case in xc_ptrace()
- PTRACE_GETREGS, PTRACE_GETFPREGS and PTRACE_GETFPXREGS are grouped into
a single case, and then with the exception of a call to FETCH_REGS(),
different code is executed based on ifing the values covered by the
case. The PTRACE_GETFPREGS and PTRACE_GETFPXREGS code is actually a
duplicate. This patch breaks the code out to two different cases.
Error Handling
* Eliminate FETCH_REGS macro as it forces several functions
to have an otherwise uneeded error_out label, mittigating
any code savins.
* Rework error handling in xc_ptrace().
- Remove FETCH_REGS as above
- Make sure that all dom0 errors are caught
- Make sure errno is always set on error
* Eliminate gotos in xc_ptrace_core.c that do nothing but return

Change the way that reboot-timeouts are handled. Rather than refreshing the
list of domains each time XendDomainInfo.refresh is called, and spawning
threads for each shutdown still in progress, we watch the control/shutdown
node and spawn just the one thread immediately. When the daemon starts (say
after a crash) all domains are checked for entries in the store indicating a
reboot in progress.
This avoids a large cost on the store and in threads when the list of domains
is refreshed. This happens every time the server is queried, so the cost can
be quite high. It's especially a high cost when using xm shutdown -a -w --
this operation should perform a lot better now.
