Subject: [PATCH V8 0/8] Add architecture agnostic code to support vCPU Hotplug
Date: Tue, 12 Mar 2024 01:59:52 +0000 [thread overview]
Message-ID: <20240312020000.12992-1-salil.mehta@huawei.com> (raw)
Virtual CPU hotplug support is being added across various architectures[1][3].
This series adds various code bits common across all architectures:
1. vCPU creation and Parking code refactor [Patch 1]
2. Update ACPI GED framework to support vCPU Hotplug [Patch 2,3]
3. ACPI CPUs AML code change [Patch 4,5]
4. Helper functions to support unrealization of CPU objects [Patch 6,7]
5. Docs [Patch 8]
Repository:
