Add self pause ability, which is required by vcpu0/dom0 when running on a AP. This can''t be satisfied by existing interface, since the new flag also serves as a sync point.

Keir: Not sure from when, at least now hvm_do_resume is double invoked in both 1: arch_vmx_do_resume from schedule_tail, and 2) vmx_asm_do_vmentry of ASM code for both x86 32 & 64 bits. I am wondering if the #1 is a redundant, can u have a double check? thx,eddie _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

...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 ctxt_switch_from with interrupt disabled, rather than introd...

Hi, I''m a PhD student trying to add some load balancing code to the credit scheduler in order to fit some specific necessities. I''m trying to understand the credit scheduler code and I don''t quite get in which part of it a pcpu starts running a vcpu. I need to keep track of when a vpcu starts running in a cpu and when it stops. Any hint on that? I think that it would

Hi all, this patch series introduces support for runstate_memory_area on ARM. The first patch moves VCPUOP_register_runstate_memory_area to common code, while the second one add VCPUOP_register_runstate_memory_area to the whilelist of vcpu_op hypercalls supported on ARM and properly updates the runstate_memory_area during vcpu context switch.
