2011-08-04usb: use iovecs in USBPacketGerd Hoffmann
Zap data pointer from USBPacket, add a QEMUIOVector instead. Add a bunch of helper functions to manage USBPacket data. Switch over users to the new interface. Note that USBPacket->len was used for two purposes: First to pass in the buffer size and second to return the number of transfered bytes or the status code on async transfers. There is a new result variable for the latter. A new status code was added to catch uninitialized result. Nobody creates iovecs with more than one element (yet). Some users are (temporarely) limited to iovecs with a single element to keep the patch size as small as possible. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-07-08usb-hub: remove unused descriptor arraysGerd Hoffmann
Somehow they where left over when converting the hub to the new usb descriptor infrastructure ... Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-07-05usb: Replace device_destroy bus op with a child_detach port opHans de Goede
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: Make port wakeup and complete ops take a USBPort instead of a DeviceHans de Goede
This makes them consistent with the attach and detach ops, and in general it makes sense to make portops take a port as argument. This also makes adding support for a companion controller easier / cleaner.

2011-05-26usb: add usb_handle_packetGerd Hoffmann
Add a usb_handle_packet function, put it into use everywhere. Right now it just calls dev->info->handle_packet(), that will change in future patches though. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-05-26usb: Pass the packet to the device's handle_control callbackHans de Goede
This allows using the generic usb_generic_handle_packet function from device code which does ASYNC control requests (such as the linux host pass through code). Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-26usb: update config descriptors to identify number of interfacesBrad Hards
Previously we relied on the .bNumInterfaces, but that won't always be accurate after the introduction of grouped interfaces. Signed-off-by: Brad Hards <bradh@frogmouth.net> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

It isn't needed any more. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: keep track of physical port address.Gerd Hoffmann
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 Hoffmann
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: hub: remote wakeup support.Gerd Hoffmann
This patch makes the usb hub handle remote wakeup requests from devices properly by updating the port status register and forwarding the wakeup to the upstream port. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: rework attach/detach workflowGerd Hoffmann
Add separate detach callback to USBPortOps, split uhci/ohci/musb/usbhub attach functions into two. Move common code to the usb_attach() function, only the hardware-specific bits remain in the attach/detach callbacks. Keep track of the port it is attached to for each usb device.

2011-01-11usb: create USBPortOps, move attach there.Gerd Hoffmann
Create USBPortOps struct, move the attach function to that struct. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: move remote wakeup handling to common codeGerd Hoffmann
This patch moves setting and clearing the remote_wakeup feature bit (via USB_REQ_{SET,CLEAR}_FEATURE) to common code. Also USB_REQ_GET_STATUS handling is moved to common code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: move USB_REQ_{GET,SET}_CONFIGURATION handling to common codeGerd Hoffmann
This patch adds fields to the USBDevice struct for the current speed (hard-wired to full speed for now) and current device configuration. Also a init function is added which inializes these fields. This allows USB_REQ_{GET,SET}_CONFIGURATION handling to be moved to common code. For most drivers the conversion is trivial ad they support a single configuration only anyway. One exception is bluetooth where some device-specific setup code runs after get/set configuration. The other is usb-net which actually has two configurations so the the code to check for the active configuration has been adapted. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb: move USB_REQ_SET_ADDRESS handling to common codeGerd Hoffmann
USB_REQ_SET_ADDRESS handling is identical in *all* emulated devices. Move it to common code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-01-11usb hub: use new descriptor infrastructure.Gerd Hoffmann
Switch the usb hub driver over to the new descriptor infrastructure. It also removes the nr_ports variable and MAX_PORTS define and introduces a NUM_PORTS define instead. The numver of ports was (and still is) fixed at 8 anyway. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2010-12-11Introduce fw_name field to DeviceInfo structure.Gleb Natapov
Add "fw_name" to DeviceInfo to use in device path building. In contrast to "name" "fw_name" should refer to functionality device provides instead of particular device model like "name" does. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-12-12qdev: Replace device names containing whitespaceMarkus Armbruster
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 Armbruster
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>
2009-10-05usb: hook unplug into qdev, cleanups + fixes.Gerd Hoffmann
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>
2009-09-09qdev/usb: make qemu aware of usb busses.Gerd Hoffmann
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.
