[Qemu-devel] [PATCH 08/11] spapr_events: add support for dedicated hotplug event source

2016-10-12 Thread Michael Roth
Hotplug events were previously delivered using an EPOW interrupt and were queued by linux guests into a circular buffer. For traditional EPOW events like shutdown/resets, this isn't an issue, but for hotplug events there are cases where this buffer can be exhausted, resulting in the loss of hotplug
