2010-04-23Make qemu-config available for toolsKevin Wolf
To be able to use config files for blkdebug, we need to make these functions available in the tools. This involves moving two functions that can only be built in the context of the emulator. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-03-16qdev: convert setting device properties to QErrorMarkus Armbruster
2010-03-16qdev: Hide "ptr" properties from usersMarkus Armbruster
Users can't set them, so qdev_device_help() shouldn't list them. Fix that. Also make qdev_prop_parse() hide them instead of printing a meaningless "has no parser" error message. Their value means nothing to users, so qdev_print_props() shouldn't print it. Fix by removing their print method. Their only use is dirty hacks. Document that.
2010-03-09qdev: Catch attempt to attach more than one device to a netdevMarkus Armbruster
Guest device and host netdev are peers, i.e. it's a 1:1 relation. However, we fail to enforce that: $ qemu -nodefaults --nographic -netdev user,id=net0 -device e1000,netdev=net0 -device virtio-net-pci,netdev=net0 -monitor stdio QEMU 0.12.50 monitor - type 'help' for more information (qemu) info network Devices not on any VLAN: net0: net=10.0.2.0, restricted=n peer=virtio-net-pci.0 e1000.0: model=e1000,macaddr=52:54:00:12:34:56 peer=net0 virtio-net-pci.0: model=virtio-net-pci,macaddr=52:54:00:12:34:57 peer=net0 It's all downhill from there.

2010-03-09qdev: Improve diagnostics for bad property valuesMarkus Armbruster
Property "vlan" reports "failed to parse" even when the value parses just fine, but the result doesn't name an existing VLAN. Similarly, properties "drive", "chr" and "netdev" misleadingly report "failed to parse" when the value doesn't name an existing host device. Change PropertyInfo method parse to return an error code, so that qdev_prop_parse() can report the error more accurately.

2010-02-03Revert "qdev: Add help for device properties"Markus Armbruster
This reverts commit 2ba6edf0dd740166632df80caa85992b20791a68. The commit has two issues: * When it runs from the monitor, e.g. "device_add e1000,?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-02-03Revert "qdev: Add help for property value"Markus Armbruster
This reverts commit 922910ce42d15bdb7c2347436b1b5798b5401de4. The commit has four issues: * When it runs from the monitor, e.g. "device_add e1000,mac=?", it prints to stderr instead of the monitor. * Help looks to callers just like failed device creation. This makes main() exit unsuccessfully on "-device e1000,mac=?". * It has an undocumented side effect on -global: "-global e1000.mac=?" prints help, but only when we actually add an e1000 device. * It does not work for properties that accept the value "?". We need to do this differently. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-26qdev: Add help for property valueStefan Weil
When called with property value "?", a help text will be printed (instead of an error message). This is useful for command lines like qemu -device e1000,mac=? and is already standard for other command line options. A better help text could be provided by extending the Property structure with a desc field. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-01-26qdev: Add help for device propertiesStefan Weil
When called with property "?", a list of supported properties will be printed (instead of an error message). This is useful for command lines like qemu -device e1000,? and was already standard for other options like model=?

2010-01-11qdev: add bit property typeMichael S. Tsirkin

2009-12-18qdev: improve property error reporting.Gerd Hoffmann
Add a error message in case we fail to parse a qdev property. Also make qemu not abort() in case setting a global property can't be set. This used to be a clear programming error. The introduction of the -global switch changed that though, so better exit instead (after printing the new error message).

2009-07-16qdev/compat: compat property infrastructure.Gerd Hoffmann
This add support for switching devices into a compatibility mode using device properties.

2009-07-16qdev: rework device properties.Gerd Hoffmann
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.
