-= How to convert to -device & friends =
-
-=== Specifying Bus and Address on Bus ===
-
-In qdev, each device has a parent bus.  Some devices provide one or
-more buses for children.  You can specify a device's parent bus with
--device parameter bus.
-
-A device typically has a device address on its parent bus.  For buses
-where this address can be configured, devices provide a bus-specific
-property.  Examples:
-
-    bus         property name       value format
-    PCI         addr                %x.%x    (dev.fn, .fn optional)
-    I2C         address             %u
-    SCSI        scsi-id             %u
-    IDE         unit                %u
-    HDA         cad                 %u
-    virtio-serial-bus  nr           %u
-    ccid-bus    slot                %u
-    USB         port                %d(.%d)*    (port.port...)
-
-Example: device i440FX-pcihost is on the root bus, and provides a PCI
-bus named pci.0.  To put a FOO device into its slot 4, use -device
-FOO,bus=/i440FX-pcihost/pci.0,addr=4.  The abbreviated form bus=pci.0
-also works as long as the bus name is unique.
-
-=== Block Devices ===
-
-A QEMU block device (drive) has a host and a guest part.
-
-In the general case, the guest device is connected to a controller
-device.  For instance, the IDE controller provides two IDE buses, each
-of which can have up to two ide-drive devices, and each ide-drive
-device is a guest part, and is connected to a host part.
-
-Except we sometimes lump controller, bus(es) and drive device(s) all
-together into a single device.  For instance, the ISA floppy
-controller is connected to up to two host drives.
-
-The old ways to define block devices define host and guest part
-together.  Sometimes, they can even define a controller device in
-addition to the block device.
-
-The new way keeps the parts separate: you create the host part with
--drive, and guest device(s) with -device.
-
-The various old ways to define drives all boil down to the common form
-
-    -drive if=TYPE,bus=BUS,unit=UNIT,OPTS...
-
-TYPE, BUS and UNIT identify the controller device, which of its buses
-to use, and the drive's address on that bus.  Details depend on TYPE.
-
-Instead of bus=BUS,unit=UNIT, you can also say index=IDX.
-
-In the new way, this becomes something like
-
-   -drive if=none,id=DRIVE-ID,HOST-OPTS...
-   -device DEVNAME,drive=DRIVE-ID,DEV-OPTS...
-
-The old OPTS get split into HOST-OPTS and DEV-OPTS as follows:
-
-* file, format, snapshot, cache, aio, readonly, rerror, werror go into
-  HOST-OPTS.
-
-* cyls, head, secs and trans go into HOST-OPTS.  Future work: they
-  should go into DEV-OPTS instead.
-
-* serial goes into DEV-OPTS, for devices supporting serial numbers.
-  For other devices, it goes nowhere.
-
-* media is special.  In the old way, it selects disk vs. CD-ROM with
-  if=ide, if=scsi and if=xen.  The new way uses DEVNAME for that.
-  Additionally, readonly=on goes into HOST-OPTS.
-
-* addr is special, see if=virtio below.
-
-The -device argument differs in detail for each type of drive:
-
-* if=ide
-
-  -device DEVNAME,drive=DRIVE-ID,bus=IDE-BUS,unit=UNIT
-
-  where DEVNAME is either ide-hd or ide-cd, IDE-BUS identifies an IDE
-  bus, normally either ide.0 or ide.1, and UNIT is either 0 or 1.
-
-* if=scsi
-
-  The old way implicitly creates SCSI controllers as needed.  The new
-  way makes that explicit:
-
-  -device lsi53c895a,id=ID
-
-  As for all PCI devices, you can add bus=PCI-BUS,addr=DEVFN to
-  control the PCI device address.
-
-  This SCSI controller provides a single SCSI bus, named ID.0.  Put a
-  disk on it:
-
-  -device DEVNAME,drive=DRIVE-ID,bus=ID.0,scsi-id=UNIT
-
-  where DEVNAME is either scsi-hd, scsi-cd or scsi-generic.
-
-* if=floppy
-
-  -global isa-fdc.driveA=DRIVE-ID
-  -global isa-fdc.driveB=DRIVE-ID
-
-  This is -global instead of -device, because the floppy controller is
-  created automatically, and we want to configure that one, not create
-  a second one (which isn't possible anyway).
-
-  Without any -global isa-fdc,... you get an empty driveA and no
-  driveB.  You can use -nodefaults to suppress the default driveA, see
-  "Default Devices".
-
-* if=virtio
-
-  -device virtio-blk-pci,drive=DRIVE-ID,class=C,vectors=V,ioeventfd=IOEVENTFD
-
-  This lets you control PCI device class and MSI-X vectors.
-
-  IOEVENTFD controls whether or not ioeventfd is used for virtqueue
-  notify.  It can be set to on (default) or off.
-
-  As for all PCI devices, you can add bus=PCI-BUS,addr=DEVFN to
-  control the PCI device address.  This replaces option addr available
-  with -drive if=virtio.
-
-* if=pflash, if=mtd, if=sd, if=xen are not yet available with -device
-
-For USB devices, the old way is actually different:
-
-    -usbdevice disk:format=FMT:FILENAME
-
-Provides much less control than -drive's OPTS...  The new way fixes
-that:
-
-    -device usb-storage,drive=DRIVE-ID,removable=RMB
-
-The removable parameter gives control over the SCSI INQUIRY removable
-(RMB) bit.  USB thumbdrives usually set removable=on, while USB hard
-disks set removable=off.
-
-Bug: usb-storage pretends to be a block device, but it's really a SCSI
-controller that can serve only a single device, which it creates
-automatically.  The automatic creation guesses what kind of guest part
-to create from the host part, like -drive if=scsi.  Host and guest
-part are not cleanly separated.
-
-=== Character Devices ===
-
-A QEMU character device has a host and a guest part.
-
-The old ways to define character devices define host and guest part
-together.
-
-The new way keeps the parts separate: you create the host part with
--chardev, and the guest device with -device.
-
-The various old ways to define a character device are all of the
-general form
-
-    -FOO FOO-OPTS...,LEGACY-CHARDEV
-
-where FOO-OPTS... is specific to -FOO, and the host part
-LEGACY-CHARDEV is the same everywhere.
-
-In the new way, this becomes
-
-    -chardev HOST-OPTS...,id=CHR-ID
-    -device DEVNAME,chardev=CHR-ID,DEV-OPTS...
-
-The appropriate DEVNAME depends on the machine type.  For type "pc":
-
-* -serial becomes -device isa-serial,iobase=IOADDR,irq=IRQ,index=IDX
-
-  This lets you control I/O ports and IRQs.
-
-* -parallel becomes -device isa-parallel,iobase=IOADDR,irq=IRQ,index=IDX
-
-  This lets you control I/O ports and IRQs.
-
-* -usbdevice serial:vendorid=VID,productid=PRID becomes
-  -device usb-serial,vendorid=VID,productid=PRID
-
-* -usbdevice braille doesn't support LEGACY-CHARDEV syntax.  It always
-  uses "braille".  With -device, this useful default is gone, so you
-  have to use something like
-
-  -device usb-braille,chardev=braille,vendorid=VID,productid=PRID
-  -chardev braille,id=braille
-
-* -virtioconsole becomes
-  -device virtio-serial-pci,class=C,vectors=V,ioeventfd=IOEVENTFD,max_ports=N
-  -device virtconsole,is_console=NUM,nr=NR,name=NAME
-
-LEGACY-CHARDEV translates to -chardev HOST-OPTS... as follows:
-
-* null becomes -chardev null
-
-* pty, msmouse, braille, stdio likewise
-
-* vc:WIDTHxHEIGHT becomes -chardev vc,width=WIDTH,height=HEIGHT
-
-* vc:<COLS>Cx<ROWS>C becomes -chardev vc,cols=<COLS>,rows=<ROWS>
-
-* con: becomes -chardev console
-
-* COM<NUM> becomes -chardev serial,path=COM<NUM>
-
-* file:FNAME becomes -chardev file,path=FNAME
-
-* pipe:FNAME becomes -chardev pipe,path=FNAME
-
-* tcp:HOST:PORT,OPTS... becomes -chardev socket,host=HOST,port=PORT,OPTS...
-
-* telnet:HOST:PORT,OPTS... becomes
-  -chardev socket,host=HOST,port=PORT,OPTS...,telnet=on
-
-* udp:HOST:PORT@LOCALADDR:LOCALPORT becomes
-  -chardev udp,host=HOST,port=PORT,localaddr=LOCALADDR,localport=LOCALPORT
-
-* unix:FNAME becomes -chardev socket,path=FNAME
-
-* /dev/parportN becomes -chardev parport,file=/dev/parportN
-
-* /dev/ppiN likewise
-
-* Any other /dev/FNAME becomes -chardev tty,path=/dev/FNAME
-
-* mon:LEGACY-CHARDEV is special: it multiplexes the monitor onto the
-  character device defined by LEGACY-CHARDEV.  -chardev provides more
-  general multiplexing instead: you can connect up to four users to a
-  single host part.  You need to pass mux=on to -chardev to enable
-  switching the input focus.
-
-QEMU uses LEGACY-CHARDEV syntax not just to set up guest devices, but
-also in various other places such as -monitor or -net
-user,guestfwd=...  You can use chardev:CHR-ID in place of
-LEGACY-CHARDEV to refer to a host part defined with -chardev.
-
-=== Network Devices ===
-
-Host and guest part of network devices have always been separate.
-
-The old way to define the guest part looks like this:
-
-    -net nic,netdev=NET-ID,macaddr=MACADDR,model=MODEL,name=ID,addr=STR,vectors=V
-
-Except for USB it looks like this:
-
-    -usbdevice net:netdev=NET-ID,macaddr=MACADDR,name=ID
-
-The new way is -device:
-
-    -device DEVNAME,netdev=NET-ID,mac=MACADDR,DEV-OPTS...
-
-DEVNAME equals MODEL, except for virtio you have to name the virtio
-device appropriate for the bus (virtio-net-pci for PCI), and for USB
-you have to use usb-net.
-
-The old name=ID parameter becomes the usual id=ID with -device.
-
-For PCI devices, you can add bus=PCI-BUS,addr=DEVFN to control the PCI
-device address, as usual.  The old -net nic provides parameter addr
-for that, which is silently ignored when the NIC is not a PCI device.
-
-For virtio-net-pci, you can control whether or not ioeventfd is used for
-virtqueue notify by setting ioeventfd= to on or off (default).
-
--net nic accepts vectors=V for all models, but it's silently ignored
-except for virtio-net-pci (model=virtio).  With -device, only devices
-that support it accept it.
-
-Not all devices are available with -device at this time.  All PCI
-devices and ne2k_isa are.
-
-Some PCI devices aren't available with -net nic, e.g. i82558a.
-
-To connect to a VLAN instead of an ordinary host part, replace
-netdev=NET-ID by vlan=VLAN.
-
-=== Graphics Devices ===
-
-Host and guest part of graphics devices have always been separate.
-
-The old way to define the guest graphics device is -vga VGA.  Not all
-machines support all -vga options.
-
-The new way is -device.  The mapping from -vga argument to -device
-depends on the machine type.  For machine "pc", it's:
-
-    std         -device VGA
-    cirrus      -device cirrus-vga
-    vmware      -device vmware-svga
-    qxl         -device qxl-vga
-    none        -nodefaults
-                disables more than just VGA, see "Default Devices"
-
-As for all PCI devices, you can add bus=PCI-BUS,addr=DEVFN to control
-the PCI device address.
-
--device VGA supports properties bios-offset and bios-size, but they
-aren't used with machine type "pc".
-
-For machine "isapc", it's
-
-    std         -device isa-vga
-    cirrus      not yet available with -device
-    none        -nodefaults
-                disables more than just VGA, see "Default Devices"
-
-Bug: the new way doesn't work for machine types "pc" and "isapc",
-because it violates obscure device initialization ordering
-constraints.
-
-=== Audio Devices ===
-
-Host and guest part of audio devices have always been separate.
-
-The old way to define guest audio devices is -soundhw C1,...
-
-The new way is to define each guest audio device separately with
--device.
-
-Map from -soundhw sound card name to -device:
-
-    ac97        -device AC97
-    cs4231a     -device cs4231a,iobase=IOADDR,irq=IRQ,dma=DMA
-    es1370      -device ES1370
-    gus         -device gus,iobase=IOADDR,irq=IRQ,dma=DMA,freq=F
-    hda         -device intel-hda,msi=MSI -device hda-duplex
-    sb16        -device sb16,iobase=IOADDR,irq=IRQ,dma=DMA,dma16=DMA16,version=V
-    adlib       not yet available with -device
-    pcspk       not yet available with -device
-
-For PCI devices, you can add bus=PCI-BUS,addr=DEVFN to control the PCI
-device address, as usual.
-
-=== USB Devices ===
-
-The old way to define a virtual USB device is -usbdevice DRIVER:OPTS...
-
-The new way is -device DEVNAME,DEV-OPTS...  Details depend on DRIVER:
-
-* ccid            -device usb-ccid
-* keyboard        -device usb-kbd
-* mouse           -device usb-mouse
-* tablet          -device usb-tablet
-* wacom-tablet    -device usb-wacom-tablet
-* host:...        See "Host Device Assignment"
-* disk:...        See "Block Devices"
-* serial:...      See "Character Devices"
-* braille         See "Character Devices"
-* net:...         See "Network Devices"
-* bt:...          not yet available with -device
-
-=== Watchdog Devices ===
-
-Host and guest part of watchdog devices have always been separate.
-
-The old way to define a guest watchdog device is -watchdog DEVNAME.
-The new way is -device DEVNAME.  For PCI devices, you can add
-bus=PCI-BUS,addr=DEVFN to control the PCI device address, as usual.
-
-=== Host Device Assignment ===
-
-QEMU supports assigning host PCI devices (qemu-kvm only at this time)
-and host USB devices.
-
-The old way to assign a host PCI device is
-
-    -pcidevice host=ADDR,dma=none,id=ID
-
-The new way is
-
-    -device pci-assign,host=ADDR,iommu=IOMMU,id=ID
-
-The old dma=none becomes iommu=off with -device.
-
-The old way to assign a host USB device is
-
-    -usbdevice host:auto:BUS.ADDR:VID:PRID
-
-where any of BUS, ADDR, VID, PRID can be the wildcard *.
-
-The new way is
-
-    -device usb-host,hostbus=BUS,hostaddr=ADDR,vendorid=VID,productid=PRID
-
-Omitted options match anything, just like the old way's wildcard.
-
-=== Default Devices ===
-
-QEMU creates a number of devices by default, depending on the machine
-type.
-
--device DEVNAME... and global DEVNAME... suppress default devices for
-some DEVNAMEs:
-
-    default device      suppressing DEVNAMEs
-    CD-ROM              ide-cd, ide-drive, scsi-cd
-    isa-fdc's driveA    isa-fdc
-    parallel            isa-parallel
-    serial              isa-serial
-    VGA                 VGA, cirrus-vga, vmware-svga
-    virtioconsole       virtio-serial-pci, virtio-serial-s390, virtio-serial
-
-The default NIC is connected to a default part created along with it.
-It is *not* suppressed by configuring a NIC with -device (you may call
-that a bug).  -net and -netdev suppress the default NIC.
-
--nodefaults suppresses all the default devices mentioned above, plus a
-few other things such as default SD-Card drive and default monitor.
