Subject: [Qemu-devel] [PATCH v2 31/31] pc: ACPI BIOS: make GPE.3 handle memory hotplug event on PIIX and Q35 machines
Date: Tue, 20 May 2014 17:15:34 +0200 [thread overview]
Message-ID: <1400598934-31921-32-git-send-email-imammedo@redhat.com> (raw)
In-Reply-To: <1400598934-31921-1-git-send-email-imammedo@redhat.com>
also make handler edge based to avoid losing events, the same as
it has been done for PCI and CPU hotplug handlers.
Signed-off-by: Igor Mammedov <imammedo@redhat.com>

v2:
* use memory hotplug crtl located under PCI0
