[PATCH v2 0/4] Implement CPU hotplug on Arm

Posted by Mykyta Poturai 5 days, 11 hours ago

This series implements support for CPU hotplug/unplug on Arm. To achieve this,
several things need to be done:

1. XEN_SYSCTL_CPU_HOTPLUG_* calls implemented.
2. timer and GIC maintenance interrupts switched to static irqactions to remove
the need for freeing them during release_irq.
3. Enabled the build of xen-hptool on Arm.

Tested on QEMU.

v1->v2:
* see individual patches

Mykyta Poturai (4):
  arm/time: Use static irqaction
  arm/gic: Use static irqaction
  arm/sysctl: Implement cpu hotplug ops
  tools: Allow building xen-hptool without CONFIG_MIGRATE
