[Qemu-devel] [PATCH 1/5] introduce powerdown_notifiers |
Date: |
Wed, 29 Aug 2012 19:02:43 +0200 |
notifier will be used for signaling powerdown request to guest in more
general way and intended to replace very specific
qemu_irq_rise(qemu_system_powerdown) and will allow to remove global
variable qemu_system_powerdown.
v2:
do not make qemu_system_powerdown static,
