From: Gonglei <arei.gong...@huawei.com>
ATCH 1 and PATCH 2 are bugfixes. PATCH 3~7 add a description
field in both ObjectProperty and PropertyInfo struct.
The descriptions can serve as documentation in the code,
and they can be used to provide better help. For example:
Before this patch series:
$./qemu-system-x86_64 -device virtio-blk-pci,?
virtio-blk-pci.iothread=link<iothread>
virtio-blk-pci.x-data-plane=bool
virtio-blk-pci.scsi=bool
virtio-blk-pci.config-wce=bool
virtio-blk-pci.serial=str
virtio-blk-pci.secs=uint32
virtio-blk-pci.heads=uint32
virtio-blk-pci.cyls=uint32
virtio-blk-pci.discard_granularity=uint32
virtio-blk-pci.bootindex=int32
virtio-blk-pci.opt_io_size=uint32
virtio-blk-pci.min_io_size=uint16
virtio-blk-pci.physical_block_size=uint16
virtio-blk-pci.logical_block_size=uint16
virtio-blk-pci.drive=str
virtio-blk-pci.virtio-backend=child<virtio-blk-device>
virtio-blk-pci.command_serr_enable=on/off
virtio-blk-pci.multifunction=on/off
virtio-blk-pci.rombar=uint32
virtio-blk-pci.romfile=str
virtio-blk-pci.addr=pci-devfn
virtio-blk-pci.event_idx=on/off
virtio-blk-pci.indirect_desc=on/off
virtio-blk-pci.vectors=uint32
virtio-blk-pci.ioeventfd=on/off
virtio-blk-pci.class=uint32
After:
$./qemu-system-x86_64 -device virtio-blk-pci,?
virtio-blk-pci.iothread=link<iothread>
virtio-blk-pci.x-data-plane=bool (on/off)
virtio-blk-pci.scsi=bool (on/off)
virtio-blk-pci.config-wce=bool (on/off)
virtio-blk-pci.serial=str
virtio-blk-pci.secs=uint32
virtio-blk-pci.heads=uint32
virtio-blk-pci.cyls=uint32
virtio-blk-pci.discard_granularity=uint32
virtio-blk-pci.bootindex=int32
virtio-blk-pci.opt_io_size=uint32
virtio-blk-pci.min_io_size=uint16
virtio-blk-pci.physical_block_size=uint16 (A power of two between 512 and 32768)
virtio-blk-pci.logical_block_size=uint16 (A power of two between 512 and 32768)
virtio-blk-pci.drive=str (ID of a drive to use as a backend)
virtio-blk-pci.virtio-backend=child<virtio-blk-device>
virtio-blk-pci.command_serr_enable=bool (on/off)
virtio-blk-pci.multifunction=bool (on/off)
virtio-blk-pci.rombar=uint32
virtio-blk-pci.romfile=str
virtio-blk-pci.addr=int32 (Slot and function number, example: 06.0)
virtio-blk-pci.event_idx=bool (on/off)
virtio-blk-pci.indirect_desc=bool (on/off)
virtio-blk-pci.vectors=uint32
virtio-blk-pci.ioeventfd=bool (on/off)
virtio-blk-pci.class=uint32
v3 -> v2:
1. add a new "description" field to DevicePropertyInfo, and format
it in qdev_device_help() in PATCH 6 (Paolo)
v2 -> v1:
1. rename "fail" label to "out" in PATCH 1 (Andreas)
2. improve descriptions in PATCH 3 (Paolo, adding Signed-off-by Paolo in this
patch)
3. rework PATCH 5, set description at qdev_property_add_static(),
then copy the description of target_obj.property. (Paolo)
4. free description filed of ObjectProperty avoid memory leak in PATCH 4.
Thanks for review!
