xen: move Xen-testing predicates to common header

2009-11-04T16:47:24+00:00

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 Signed-off-by: Jesse Barnes

xen: honour VCPU availability on boot

2009-04-08T21:25:51+00:00

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.

cpumask: make Xen use the new operators.

2009-03-13T04:19:56+00:00

Impact: cleanup In particular, *map are deprecated, and you have to use the accessors as *mask are const. Signed-off-by: Rusty Russell To: Jeremy Fitzhardinge

xen: implement CPU hotplugging

2008-08-25T09:25:14+00:00

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.
