2009-11-04xen: move Xen-testing predicates to common headerJeremy Fitzhardinge1-0/+1
Move xen_domain and related tests out of asm-x86 to xen/xen.h so they can be included whenever they are necessary. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-04-08xen: honour VCPU availability on bootIan Campbell1-10/+30
If a VM is booted with offline VCPUs then unplug them during boot. Determining the availability of a VCPU requires access to XenStore which is not available at the point smp_prepare_cpus() is called, therefore we bring up all VCPUS initially and unplug the offline ones as soon as XenStore becomes available.

2009-03-13cpumask: make Xen use the new operators.Rusty Russell1-2/+2
Impact: cleanup In particular, *map are deprecated, and you have to use the accessors as *mask are const. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> To: Jeremy Fitzhardinge <jeremy@xensource.com>

2008-08-25xen: implement CPU hotpluggingAlex Nixon1-0/+90
Note the changes from 2.6.18-xen CPU hotplugging: A vcpu_down request from the remote admin via Xenbus both hotunplugs the CPU, and disables it by removing it from the cpu_present map, and removing its entry in /sys. A vcpu_up request from the remote admin only re-enables the CPU, and does not immediately bring the CPU up. A udev event is emitted, which can be caught by the user if he wishes to automatically re-up CPUs when available, or implement a more complex policy.
