2012-03-13usb: the big renameGerd Hoffmann1-1408/+0
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. Host adapters are prefixed with "hch-" now, usb device emulations are prefixed with "dev-". Fixup paths Makefile and include paths to make it compile. No code changes.

2012-03-07usb: add USB_RET_IOERRORHans de Goede1-0/+1
We already have USB_RET_NAK, but that means that a device does not want to send/receive right now. But with host / network redirection we can actually have a transaction fail due to some io error, rather then ie the device just not having any data atm. This patch adds a new error code named USB_RET_IOERROR for this, and uses it were appropriate. Notes: -Currently all usb-controllers handle this the same as NODEV, but that may change in the future, OHCI could indicate a CRC error instead for example. -This patch does not touch hw/usb-musb.c, that is because the code in there handles STALL and NAK specially and has a if status < 0 generic catch all for all other errors Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-15qom: Unify type registrationAndreas Färber1-2/+3

2012-02-10usb: Set USBEndpoint in usb_packet_setup().Gerd Hoffmann1-6/+7
With the separation of the device lookup (via usb_find_device) and packet processing we can lookup device and endpoint before setting up the usb packet. So we can initialize USBPacket->ep early and keep it valid for the whole lifecycle of the USBPacket. Also the devaddr and devep fields are not needed any more.

2012-02-10usb: USBPacket: add status, rename owner -> epGerd Hoffmann1-2/+2
Add enum to track the status of USBPackets, use that instead of the owner pointer to figure whenever a usb packet is currently in flight or not. Add some more packet status sanity checks. Also rename the USBEndpoint pointer from "owner" to "ep". Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2012-02-10usb: kill USB_MSG_RESETGerd Hoffmann1-7/+3
The USB subsystem pipes internal reset notifications through usb_handle_packet() with a special magic PID. This indirection is a pretty pointless excercise as it ends up being handled by usb_generic_handle_packet anyway. Replace the USB_MSG_RESET with a usb_device_reset() function which can be called directly. Also rename the existing usb_reset() function to usb_port_reset() to avoid confusion. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-10usb-uhci: implement bandwidth managementGerd Hoffmann1-7/+22
The OS is allowed to make the UHCI Controller run in circles. That is usually done to serve multiple connected USB devices in a robin-round fashion, so the available USB bandwidth is evenly distributed between devices. The uhci emulation handles this in a very poor way though. When it figures it runs in circles it stops processing unconditionally, so it usually processes at most a single transfer desriptor per queue, even if there are multiple transfer descriptors are queued up. This patch makes uhci act in a more sophisticated way. It keeps track of successful processed transfer descriptors and transfered bytes. Then it will stop processing when there is nothing to do (no transfer descriptor was completed the last round) or when the transfered data reaches the usb bandwidth limit. Result is that the usb-storage devices connected to uhci are ten times faster, mkfs.vfat time for a 64M stick goes down from five seconds to a half second. Reason for this is that we are now processing up to 20 transfer descriptors (with 64 bytes each) per frame instead of a single one. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-02-03qdev: register all types natively through QEMU Object ModelAnthony Liguori1-42/+54
This was done in a mostly automated fashion. I did it in three steps and then rebased it into a single step which avoids repeatedly touching every file in the tree. The first step was a sed-based addition of the parent type to the subclass registration functions. The second step was another sed-based removal of subclass registration functions while also adding virtual functions from the base class into a class_init function as appropriate. Finally, a python script was used to convert the DeviceInfo structures and qdev_register_subclass functions to TypeInfo structures, class_init functions, and type_register_static calls. We are almost fully converted to QOM after this commit. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

These are various small stylistic changes which help make things more consistent such that the automated conversion script can be simpler. It's not necessary to agree or disagree with these style changes because all of this code is going to be rewritten by the patch monkey script anyway.

2011-12-12Remove unnecessary casts from PCI DMA code in usb-uhciDavid Gibson1-10/+7

2011-11-01usb-uhci: Use PCI DMA stub functionsDavid Gibson1-11/+11

2011-10-13usb: fix port resetGerd Hoffmann1-1/+1
commit 891fb2cd4592b6fe76106a69e0ca40efbf82726a removed the implicit detach before (re-)attaching in usb_attach(). Some usb host controllers used that behavior though to do a port reset by a detach+attach sequence. This patch establishes old behavior by adding a new usb_reset() function for port resets and putting it into use, thereby also unifying port reset behavior of all host controllers. The patch also adds asserts to usb_attach() and usb_detach() to make sure the calls are symmetrical. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-09-19pci: interrupt pin documentation updateMichael S. Tsirkin1-1/+1

2011-09-07usb: claim port at device initialization time.Gerd Hoffmann1-5/+6
This patch makes qemu assign a port when creating the device, not when attaching it. For most usb devices this isn't a noticable difference because they are in attached state all the time. The change affects usb-host devices which live in detached state while the real device is unplugged from the host. They have a fixed port assigned all the time now instead of getting grabbing one on attach and releasing it at detach, i.e. they stop floating around at the usb bus. The change also allows to simplify usb-hub. It doesn't need the handle_attach() callback any more to configure the downstream ports. This can be done at device initialitation time now. The changed initialization order (first grab upstream port, then register downstream ports) also fixes some icky corner cases. For example it is not possible any more to plug the hub into one of its own downstream ports. The usb host adapters must care too. USBPort->dev being non-NULL doesn't imply any more the device is in attached state. The host adapters must additionally check the USBPort->dev->attached flag.

2011-08-04usb: use iovecs in USBPacketGerd Hoffmann1-21/+17
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>

2011-07-05usb: Replace device_destroy bus op with a child_detach port opHans de Goede1-8/+10
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.

This was done with: sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \ $(git grep -l 'qemu_get_clock\>' ) sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \ $(git grep -l 'qemu_new_timer\>' ) after checking that get_clock and new_timer never occur twice on the same line. There were no missed occurrences; however, even if there had been, they would have been caught by the compiler. There was exactly one false positive in qemu_run_timers: - current_time = qemu_get_clock (clock); + current_time = qemu_get_clock_ns (clock); which is of course not in this patch.
