[Qemu-devel] [PATCH v3 03/10] acpi, mem-hotplug: Add acpi_send_gpe_event() to rise sci for memory hotplug. |
Date: |
Thu, 26 Feb 2015 09:16:45 +0800 |
From: Tang Chen <address@hidden>
Add a new API named acpi_send_gpe_event() to send memory hotplug SCI.
Doing this is because this procedure will be used by other functions in the
next coming patches.
