2014-01-16usb: add support for microsoft os descriptorsGerd Hoffmann1-0/+2
This patch adds support for special usb descriptors used by microsoft windows. They allow more fine-grained control over driver binding and adding entries to the registry for configuration. As this is a guest-visible change the "msos-desc" compat property has been added to turn this off for 1.7 + older Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-11-05qdev: Drop misleading qdev_free() functionStefan Hajnoczi1-3/+4
The qdev_free() function name is misleading since all the function does is unlink the device from its parent. The device is not necessarily freed. The device will be freed when its QObject refcount reaches zero. It is usual for the parent (bus) to hold the final reference but there are cases where something else holds a reference so "free" is a misleading name. Call object_unparent(obj) directly instead of having a qdev wrapper function.

2013-01-10Make all static TypeInfos constAndreas Färber1-1/+1
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-07usb: Add an usb_device_ep_stopped USBDevice methodHans de Goede1-0/+8
Some usb devices (host or network redirection) can benefit from knowing when the guest stops using an endpoint. Redirection may involve submitting packets independently from the guest (in combination with a fifo buffer between the redirection code and the guest), to ensure that buffers of the real usb device are timely emptied. This is done for example for isoc traffic and for interrupt input endpoints. But when the (re)submission of packets is done by the device code, then how does it know when to stop this? For isoc endpoints this is handled by detecting a set interface (change alt setting) command, which works well for isoc endpoints. But for interrupt endpoints currently the redirection code never stops receiving data from the device, which is less then ideal. However the controller emulation is aware when a guest looses interest, as then the qh for the endpoint gets unlinked (ehci, ohci, uhci) or the endpoint is explicitly stopped (xhci). This patch adds a new ep_stopped USBDevice method and modifies the hcd code to call this on queue unlink / ep stop. This makes it possible for the redirection code to properly stop receiving interrupt input (*) data when the guest no longer has interest in it. *) And in the future also buffered bulk input.

2012-11-08usb: split packet result into actual_length + statusHans de Goede1-8/+5
Since with the ehci and xhci controllers a single packet can be larger then maxpacketsize, it is possible for the result of a single packet to be both having transferred some data as well as the transfer to have an error. An example would be an input transfer from a bulk endpoint successfully receiving 1 or more maxpacketsize packets from the device, followed by a packet signalling halt. While already touching all the devices and controllers handle_packet / handle_data / handle_control code, also change the return type of these functions to void, solely storing the status in the packet. To make the code paths for regular versus async packet handling more uniform. This patch unfortunately is somewhat invasive, since makeing the qemu usb core deal with this requires changes everywhere. This patch only prepares the usb core for this, all the hcd / device changes are done in such a way that there are no functional changes. This patch has been tested with uhci and ehci hcds, together with usb-audio, usb-hid and usb-storage devices, as well as with usb-redir redirection with a wide variety of real devices. Note that there is usually no need to directly set packet->actual_length form devices handle_data callback, as that is done by usb_packet_copy() Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

This can be used by usb-device code which wishes to process an entire endpoint queue at once, to do this the usb-device code returns USB_RET_ADD_TO_QUEUE from its handle_data class method and defines a flush_ep_queue class method to call when the hcd is done queuing up packets.

2012-06-18qdev: Convert busses to QEMU Object ModelAnthony Liguori1-8/+17
This is far less interesting than it sounds. We simply add an Object to each BusState and then register the types appropriately. Most of the interesting refactoring will follow in the next patches. Since we're changing fundamental type names (BusInfo -> BusClass), it all needs to convert at once. Fortunately, not a lot of code is affected.

2012-06-18qdev: Move bus properties to abstract superclassesPaolo Bonzini1-1/+1
In qdev, each bus in practice identified an abstract superclass, but this was mostly hidden. In QOM, instead, these abstract classes are explicit so we can move bus properties there. All bus property walks are removed, and all device property walks are changed to look along the class hierarchy instead. We would have duplicates if class A defines some properties and its subclass B does not define any, because class_b->props will be left equal to class_a->props. The solution here is to reintroduce the class_base_init TypeInfo callback, that was present in one of the early QOM versions but removed (on my request...) before committing. This breaks global bus properties, an obscure feature when used with the command-line which is actually useful and used when used by backwards-compatible machine types. So this patch also adjusts the global bus properties in hw/pc_piix.c to refer to the abstract class. Globals and other properties must be modified in the same patch to avoid complications related to initialization ordering.

2012-04-17usb/vmstate: add parent dev pathGerd Hoffmann1-1/+16
... to make vmstate id string truely unique with multiple host controllers, i.e. move from "1/usb-ptr" to "0000:00:01.3/1/usb-ptr" (usb tabled connected to piix3 uhci). This obviously breaks migration. To handle this the usb bus property "full-path" is added. When setting this to false old behavior is maintained. This way current qemu will be compatible with old versions when started using '-M pc-$oldversion'. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Reorganize usb source files. Create a new hw/usb/ directory and move all usb source code to that place. Also make filenames a bit more descriptive.
