...e is actually saved. This leads to possible nasty races when interrupts need to be injected after is_running is set to the next vcpu but before the currently running gic state has been saved from the previous vcpu. Use current instead of is_running to check which one is the currently running vcpu: set_current is called right before __context_switch and schedule_tail with interrupt disabled. Re-enabled interrupts after ctxt_switch_from, so that all the context switch saving functions don''t have to worry about receiving interrupts while saving state. Changes in v2: - rework the patch to run ct...

This patch implements cpu offline feature. Best Regards Haitao Shan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi all, I am having confusion regarding the way a newly created domain is allocated vcpu. Initially during dom0 creation alloc_vcpu is called to create vcpu structs for all the available cpu''s and assigned to dom0. But its not the case for domU creation. 1. So how will dom0 relinquish/share vcpu to/with a newly created domU. Does this happen as part of the shared_info page mapping??

This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between

Hi all, these are the remaining unapplied patches of the ARM HDLCD patch series. Changes in v7: - rebased on b61ed421d2c85b5b106c63f2c14f8aa162b282f0; - turn more printk and panic into early_printk and early_panic. Changes in v6: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795; - remove useless initializations to NULL in lfb_init; - more compact checks in lfb_init. Changes in v5: - move

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See

Hello everyone, this is the very first version of the patch series that introduces ARMv7 with virtualization extensions support in Xen.

First off, Apologies for the massive patch series... This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8 (AArch64) model. The kernel is the same one as I am currently using with the 32 bit hypervisor I haven''t yet tried starting a guest or anything super advanced like that ;-). Also there is not real support for 64-bit domains at all, although in one or two places I
