From ee6847d19be16c789b8bd4e553b7cd6701ba1245 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 15 Jul 2009 13:43:31 +0200 Subject: qdev: rework device properties. This patch is a major overhaul of the device properties. The properties are saved directly in the device state struct now, the linked list of property values is gone. Advantages: * We don't have to maintain the list with the property values. * The value in the property list and the value actually used by the device can't go out of sync any more (used to happen for the pci.devfn == -1 case) because there is only one place where the value is stored. * A record describing the property is required now, you can't set random properties any more. There are bus-specific and device-specific properties. The former should be used for properties common to all bus drivers. Typical use case is bus addressing, i.e. pci.devfn and i2c.address. Properties have a PropertyInfo struct attached with name, size and function pointers to parse and print properties. A few common property types have PropertyInfos defined in qdev-properties.c. Drivers are free to implement their own very special property parsers if needed. Properties can have default values. If unset they are zero-filled.
