From 5a2223ca26b1a34e131b5b9a63599d9426d2c25c Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Sun, 26 Jan 2014 12:31:27 +0200 Subject: pcihp: reduce number of device check events PIIX created a made-up value for the UP register since it was read by guest 32 times for each interrupt. There's no reason to do this for the new PCIHP: register is only read once for each interrupt, so clean up code by making read act as an interrupt acknowledgement: the new UP register clear on read. In this way we cut down the number of bus rescans by a factor of 32, and drop a bunch of code that's now unused. Signed-off-by: Michael S.

However it limits this only to PCI devices and prevents from generalizing hotplug code. So add similar field to DeviceClass so it could be reused with other Devices and would allow to replace PCI specific hotplug callbacks with generic implementation. Following patches will replace PCIDeviceClass.no_hotplug with this new property. In addition expose field as "hotpluggable" readonly property, to make it possible to read its value via QOM interface.
