From 28df36a13a3b0b792d9df64f8db8a392df5e0b35 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Fri, 6 Feb 2015 14:55:51 +1100 Subject: pseries: Make the PAPR RTC a qdev device At present the PAPR RTC isn't a "device" as such - it's accessed only via firmware/hypervisor calls, and is handled in the sPAPR core code. This becomes inconvenient as we extend it in various ways. This patch makes the PAPR RTC a separate device in the qemu device model. For now, the only piece of device state - the rtc_offset - is still kept in the global sPAPREnvironment structure. That's clearly wrong, but leaving it to be fixed in a following patch makes for a clearer separation between the internal re-organization of the device, and the behavioural changes (because the migration stream format needs to change slightly when the offset is moved into the device's own state).
