...ext 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 introducing a gic_running internal variable. Signed-off-by: Stefano Stabelli...

Hi, I want to try Xen on ARMv8 Simulator. Can you please provide guidance?. I am looking for information about sources, build and procedure to launch Xen on ARMv8 Thanks & Regards Vijay

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.

Hello, This is the second version of this patch series. I only implement the VPF context switch support for arm32 and add dummy function to avoid compilation on arm64. I have switched the order of the patch because the old second one can be applied alone and the patch are cleaner :). For all the changes see each patch. Cheers, Julien Grall (2): xen/arm: don''t enable VFP on 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

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.

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
