X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~162^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c5bc152bc399ae7ec8ac5227762e4320d0fd2d1c;p=sdk%2Femulator%2Fqemu.git

spapr_pci: emit hotplug add/remove events during hotplug

This uses extension of existing EPOW interrupt/event mechanism
to notify userspace tools like librtas/drmgr to handle
in-guest configuration/cleanup operations in response to
device_add/device_del.

Userspace tools that don't implement this extension will need
to be run manually in response/advance of device_add/device_del,
respectively.
