2011-07-08usb_register_port(): do not set port->opaque and port->index twiceJes Sorensen1-2/+0

2011-07-05usb: Replace device_destroy bus op with a child_detach port opHans de Goede1-2/+0
Note this fixes 2 things in one go, first of all the device_destroy bus op should be a device_detach bus op, as pending async packets from the device should be cancelled on detach not on destroy. Secondly having this as a bus op won't work with companion controllers, since then there will be 1 bus driven by the ehci controller and thus 1 set of bus ops, but the device being detached may be downstream of a handed over port. Making the detach of a downstream device a port op allows the ehci controller to forward this to the companion controller port for handed over ports.

2011-07-05usb: Add a register_companion USB bus op.Hans de Goede1-0/+31
This is a preparation patch for adding support for USB companion controllers. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-07-05usb: Move (initial) call of usb_port_location to usb_fill_portHans de Goede1-0/+1
Cleanup / preparation patch for companion controller support. Note that as a "side-effect" this patch also fixes the milkymist-softusb controller not having a port_location set for its ports. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-bus: Don't detach non attached devices on device exitHans de Goede1-1/+3
This causes an "Error: tried to detach unattached usb device " to be printed, this can happen when deleting ie a usb host qdev, which did not get attached (because a device matching the filter never got plugged in). Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-bus: Add knowledge of USB_SPEED_SUPER to usb_speed helperHans de Goede1-0/+1
Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb: cancel async packets on unplugGerd Hoffmann1-1/+4
This patch adds USBBusOps struct with (for now) only a single callback which is called when a device is about to be destroyed. The USB Host adapters are implementing this callback and use it to cancel any async requests which might be in flight before the device actually goes away. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Avoid this warning from OpenBSD linker: LINK i386-softmmu/qemu ../usb-bus.o(.text+0x27c): In function `usb_get_fw_dev_path': /src/qemu/hw/usb-bus.c:294: warning: sprintf() is often misused, please use snprintf() Signed-off-by: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-24usb core: add migration supportGerd Hoffmann1-0/+16
Yes, seriously. There is no migration support at all for usb devices. They loose state, especially the device address, and stop responding because of that. Oops. Luckily there is so much broken usb hardware out there that the guest usually just kicks the device hard (via port reset and reinitialization), then continues without a hitch. So we got away with that in a surprising high number of cases. The arrival of remote wakeup (which enables autosuspend support) changes that picture though. The usb devices also forget that it they are supposed to wakeup, so they don't do that. The host also doesn't notice the device stopped working in case it suspended the device and thus expects it waking up instead of polling it. Result is that your mouse is dead. Lets start fixing that. Add a vmstate struct for USBDevice. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-12usb: zap pdev from usbportGerd Hoffmann1-2/+1
It isn't needed any more. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-12usb: rewrite fw path, fix numberingGerd Hoffmann1-42/+26
This patch rewrites the firmware path code to use the physical port location tracking just added to the qemu usb core. It also fixes the port numbering to start with "1" in the firmware path. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: add port property.Gerd Hoffmann1-4/+22
This allows to explictily set the physical port where you want to plug the usb device. Example: -device usb-tablet,bus=usb.0,port=2 With explicit port addressing qemu can and will not automagically add USB Hubs. This means that: (a) You can plug two devices of your choice into the two uhci root ports. (b) If you want plug in more that two devices you have to care about adding a hub yourself. Plugging a hub works this way: -device usb-hub,bus=usb.0,port=1 Use this to add a device to the hub: -device usb-tablet,bus=usb.0,port=1.1 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: keep track of physical port address.Gerd Hoffmann1-3/+23
Add a path string to USBPort. Add usb_port_location() function to set the physical location of the usb port. Update all drivers implementing usb ports to call it. Update the monitor commands to print it. Wind it up in qdev. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: add speed mask to portsGerd Hoffmann1-1/+2
Add a field to usb ports indicating the speed(s) they are able to handle. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: create USBPortOps, move attach there.Gerd Hoffmann1-2/+4
Create USBPortOps struct, move the attach function to that struct. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb descriptors: add settable strings.Gerd Hoffmann1-0/+1

2010-04-02usb-bus: fix no paramsTeLeMan1-1/+1
After commit 702f3e0fb52c124c07f215426eeadb70a716643f, the params is nerver NULL. It should check *params instead of params to determine whether the params is empty. Signed-off-by: TeLeMan <geleman@gmail.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-03-17Avoid crash on '-usbdevice <device>' without parametersJan Kiszka1-1/+3
Many usbdevice_init implementors assume params is non-NULL. Signed-off-by: Jan Kiszka <jan.kiszka@web.de> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-03-16error: Replace qemu_error() by error_report()Markus Armbruster1-2/+2
error_report() terminates the message with a newline. Strip it it from its arguments. This fixes a few error messages lacking a newline: net_handle_fd_param()'s "No file descriptor named %s found", and tap_open()'s "vnet_hdr=1 requested, but no kernel support for IFF_VNET_HDR available" (all three versions). There's one place that passes arguments without newlines intentionally: load_vmstate(). Fix it up.
2010-02-25Fix -usbdevice crashPaul Brook1-0/+3
If -usbdevice is used on a machine with no USB busses, usb_create will fail and return NULL. Patch below handles this failure gracefully rather than crashing when we try to init the device. Signed-off-by: Paul Brook <paul@codesourcery.com>
2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster1-1/+1
Device names with whitespace require quoting in the shell and in the monitor. Some of the offenders are also overly long. Some have a more convenient alias, some don't. The place for verbose device names is DeviceInfo member desc. The name should be short & sweet.

2009-12-12qdev: Separate USB product description from qdev nameMarkus Armbruster1-1/+1
Using the qdev name for the product description makes for inconvenient qdev names. Put the product description in new USBDeviceInfo member product_desc. Make usb_qdev_init() use it. No user or guest visible change, since the value is still the same. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-12-12qdev: Rename USBDevice member devname to product_descMarkus Armbruster1-5/+6

2009-10-30usb: make attach optional.Gerd Hoffmann1-1/+2
Add a auto_attach field to USBDevice, which is enabled by default. USB drivers can clear this field in case they do *not* want the device being attached (i.e. plugged into a usb port) automatically after successfull init(). Use cases (see next patches): * attaching encrypted mass storage devices. * -usbdevice host:... Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-10-30usb core: use qdev for -usbdeviceGerd Hoffmann1-0/+47
This patchs adds infrastructure to handle -usbdevice via qdev callbacks. USBDeviceInfo gets a name field (for the -usbdevice driver name) and a callback for -usbdevice parameter parsing. The new usbdevice_create() function walks the qdev driver list and looks for a usb driver with a matching name. When a parameter parsing callback is present it is called, otherwise the device is created via usb_create_simple().

2009-10-07New qdev_init_nofail()Markus Armbruster1-1/+1
Like qdev_init(), but terminate program via hw_error() instead of returning an error value. Use it instead of qdev_init() where terminating the program on failure is okay, either because it's during machine construction, or because we know that failure can't happen. Because relying in the latter is somewhat unclean, and the former is not always obvious, it would be nice to go back to qdev_init() in the not-so-obvious cases, only with proper error handling. I'm leaving that for another day, because it involves making sure that error values are properly checked by all callers.

2009-10-05usb: hook unplug into qdev, cleanups + fixes.Gerd Hoffmann1-8/+49
Hook into DeviceInfo->exit(). handle_destroy() must not free the state struct, this is handled by the new usb_qdev_exit() function now. qdev_free(usb_device) works now. Fix usb hub to qdev_free() all connected devices on unplug. Unplugging a usb hub works now. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-09-12Fix sys-queue.h conflict for goodBlue Swirl1-16/+16
Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896, f40d753718c72693c5f520f0d9899f6e50395e94, 96555a96d724016e13190b28cffa3bc929ac60dc and 3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file. Revert the previous hacks. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2009-09-09qdev/usb: make qemu aware of usb busses.Gerd Hoffmann1-4/+136
Move usb code from vl.c to usb-bus.c and make it use the new data structures added by qdev conversion. qemu usb core should be able to handle multiple USB busses just fine now (untested though). Kill some usb_*_init() legacy functions, use usb_create_simple() instead. Kill some FIXMEs added by the first qdev/usb patch.
