Subject: [PATCH] arm/virt/acpi: Build CPUs AML with CPU Hotplug support
|
|
|
|
Support of vCPU Hotplug requires sequence of ACPI handshakes between Qemu and
|
|
Guest kernel when a vCPU is plugged or unplugged. Most of the AML code to
|
|
support these handshakes already exists. This AML need to be build during VM
|
|
init for ARM architecture as well if the GED support exists.
