[Qemu-devel] [PATCH 09/22] introduce CPU hot-plug notifier |
Date: |
Fri, 5 Apr 2013 16:37:01 +0200 |
hot-added CPU will be distributed to acpi_piix4, rtc_cmos and icc_bridge
Signed-off-by: Igor Mammedov <address@hidden>
---
v2:
* move notifier to qom/cpu.c and call it from CPUClass.realize() on hotplug
