Treat xenstore UUID for domU's like MAC addresses for virtual network
interfaces -- can be set by user in domU configuration, but is
generated randomly by default.
Separate the validity checking of the page frame in 2 chunks.
give a more accurate error message, and don't call pfn_to_page before

Rev8517 (Reduce locked critical region in __enter_scheduler()), enable
interrupt now before context switch. Then arch specific context_switch
stub needs to disable interrupt itself.
Adding __init__.py file to remove build warning.
It turns out the hg export command does not include zero
size files in the generated diff and this was overlooked.

This patch make xm reboot/shutdown work for vmx doamin.
xm reboot fails due to two issues:
1. no mechanism to change XendDomainInfo.info to trigger domain reboot
2. ioemu blkif parameter is missing during reboot, thus device model recreation will fail.
This patch fix these issues by
1. introducing a xswatch to monitor the control/shutdown node. once fired, it will change the XendDomainInfo.info to trigger domain reboot
2. saving the ioemu blkif parameter in xen store just like DomU does.
The present pud_offset_k implementation runs the value read through
the m2p translation process twice. With that removed, it can then
also be simplified.
Allow disabling the tx checksums on the xen loopback
interface, which is used for the virtual interfaces of dom0 instead
of netfront/netback.
I need to issue ethtool -K eth0 tx off to work around a bad checksum
problem, which has been reported for domUs a few months ago. I'm
bridging dom0's eth0 to a domU where I do NAT to a different virtual
interface. Without this change, I get lots of packets with bad
checksums.
Having /usr/bin/xsls conflicts with xsls as distributed in scalapack
(http://www.netlib.org/scalapack/). It should probably be xenstore-ls
a) for namespacing and b) to match up with the other xenstore commands
better.
Remove the spin on VCPUF_running from context_switch().
It doesn't work because we already set VCPUF_running
locally, and the scheduler should not pick another CPU's
VCPUF_running VCPU anyway, since it mustn't modify the
processor field.
Instead just add a simple assertion to the scheduler to
ensure the scheduling algorithm is not picking an
inappropriate VCPU.
Remove the free_vcpu() interface I added in the preceding
changeset. It makes no sense, since an allocated VCPU
cannot be freed at any arbitrary point because individual
VCPUs are not refcounted.
Instead extend free_domain() slightly so it really does do
the reverse of alloc_vcpu() for every allocated VCPU.
Interface name changes:
1. do_createdomain -> domain_create
2. domain_destruct -> domain_destroy
Arch-specific changes:
1. arch_do_createdomain -> arch_domain_create
This function now takes a domain pointer, not a VCPU
pointer! Initialisation of VCPU0 must happen in
alloc_vcpu_struct().
2. free_perdomain_pt -> arch_domain_destroy
This function must undo the work of arch_domain_create
TODO: arch_domain_create() refactoring is not completed
for ia64.
Arch-specific per-vcpu info should be initialised to zero
when allocating a new vcpu structure, not copied from
CPU0's idle VCPU. Especially now that the idle VCPU itself
is dynamically allocated.
This should fix assertions people have been seeing in
getdomain_info_ctxt() relation to IOPL in eflags.

Introduce a locking protocol for acquiring the 'scheduler
lock' on a particular VCPU. Since this requires acquiring
the approrpiate per-CPU lock, we must re-check the VCPU's
current CPU binding after the lock is acquired.
Fix up the way we initialise and set the NMI heartbeat
timers. Also, compund updates to APIC ICR and ICR2 registers
must be done with interrupts disabled to ensure local
atomicity.
Debug keyhandlers for triggering an NMI and examine current NMI state.
Add 'N' keyhandler to dump the current per CPU NMI counts and the
current NMI mask/pending status.
Add 'n' keyhandler to trigger an NMI by sending an IPI. For some
reason the destination shorthand for self is not valid when used with
the NMI delivery mode so we send the IPI to our own APIC ID
explicitly.

Ensure watchdog remains disabled unless enabled on the command line.
Bail out of setup_apic_nmi_watchdog() early if watchdog is not
enabled. Is the watchdog is disabled then increment
watchdog_disable_count to prevent it ever becoming enabled.
Unconditionally call setup_apic_nmi_watchdog() from setup_local_APIC()
so that the above is guaranteed to have occurred before the first call
of watchdog_enable().

Add a new timer operation kill_timer(). Effectively the
'opposite' of init_timer(), it marks the end of a timer's
lifetime. After this call the timer will not be pending,
its callback handler will not be running, and future calls
to set_timer() will silently fail.
Update copyright on domain_page implementation. It's been
rewritten from scratch a couple of times now and it's safe
to assert that the original Linux heritage was deleted
long ago.
Re-enable per-cpu cache on map_domain_page(). Fix the
offending caller that broke the vcpu cache (writable
pagetable code kept a mapping outstanding until flush,
which could occur on a different vcpu).
Adds a check to vtpm_manager and vtpm Makefiles to verify openssl and
gmp dev files are installed. If files are missing, Makefile exits with a
message indicating that these tools will not be built, rather than an
error, which prevents Xen from building.
8604:a51fcb5de470 introduced a discrepancy between the declaration
and definition of xc_linux_save(). In particular the argument for
the suspend pointer to function was null in one and int in the other.
On inspection, int seemed to be correct, so I went with this.
I also fixed up a few other cosmetic discrepancies.
Fix cpu_affinity memcpy() (bytes not longs!) add add a better
affinity map sanity check to avoid blowing up Xen if no
online cpu is included in the map.
