From c5bc152bc399ae7ec8ac5227762e4320d0fd2d1c Mon Sep 17 00:00:00 2001 From: Tyrel Datwyler Date: Thu, 7 May 2015 15:33:56 +1000 Subject: [PATCH] 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.
