Subject: [PATCH v1 0/4] Implement CPU hotplug on Arm
Date: Thu, 18 Sep 2025 12:16:32 +0000 [thread overview]
Message-ID: <cover.1758197507.git.mykyta_poturai@epam.com> (raw)
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.
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
