2011-06-14virtio: compat event idx supportMichael S. Tsirkin
Disable event index for compat machine types. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-06-14usb-uhci: fix expire time initialization.Gerd Hoffmann
expire_time must be initialited when the guest activates the usb scheduler, not at device creation time. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14hw/usb-ohci.c: Implement remote wakeupPeter Maydell
Implement the wakeup callback in the OHCI USBPortOps, so that when a downstream device wakes up it correctly causes the OHCI controller to come out of suspend. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14hw/usb-ohci.c: Ignore writes to HcPeriodCurrentED registerPeter Maydell
HcPeriodCurrentED is read-only, but Linux writes to it anyway; silently ignore this rather than printing a warning message. (Specifically, drivers/usb/host/ohci-hub.c:ohci_rh_resume() writes a 0, in at least kernels 2.6.25 through 2.6.39.)

2011-06-14usb-bus: Don't detach non attached devices on device exitHans de Goede
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-ehci: itd handling fixes.Gerd Hoffmann
This patch fixes a bunch of issues in the itd descriptor handling. Most important fix is to handle transfers which cross page borders correctly by looking up the address of the next page. Luckily the linux uses physically contigous memory so the data used to hits the correct location even with this bug instead of corrupting guest memory. Also the transfer length updates for outgoing transfers wasn't correct. While being at it DPRINTFs have been replaced by tracepoints. The isoch_pause logic has been disabled. Not clear to me which propose this serves and I think it is incorrect too as we just skip processing itds. Even when no xfer happens we have to clear the active bit.

2011-06-14The USB tablet should not claim boot protocol support.Kevin O'Connor
The USB tablet advertises that it supports the "boot" protocol. However, its reports aren't "boot" protocol compatible. So, it shouldn't claim that. Signed-off-by: Kevin O'Connor <kevin@koconnor.net> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14Fix USB mouse Set_Protocol behaviorKevin O'Connor
The QEMU USB mouse claims to support the "boot" protocol (bInterfaceSubClass is 1). However, the mouse rejects the Set_Protocol command. The qemu mouse does support the "boot" protocol specification, so a simple fix is to enable the Set_Protocol request.

2011-06-14usb-ehci: drop EXECUTING checks.Gerd Hoffmann
The state machine doesn't stop in EXECUTING state any more when async packets are in flight, so the checks are not needed any more and can be dropped. Also kick out the check for the frame timer. As we don't stop & sleep any more on async packets this is obsolete. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb: cancel async packets on unplugGerd Hoffmann
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.

2011-06-14usb-ehci: fix error handling.Gerd Hoffmann
Set the correct bits for nodev, stall and babble errors. Raise errint irq. Fix state transition from WRITEBACK to the next state. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: fix offset writeback in ehci_buffer_rwGerd Hoffmann
Two bugs at once: First the mask is backwards, so the it used to keeps the offset and clears the page address, which is not what we need when we update the offset. Second the offset calculation is wrong in case head isn't page aligned. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: multiqueue supportGerd Hoffmann
This patch adds support for keeping multiple queues going at the same time. One slow device will not affect other devices any more. The patch adds code to manage EHCIQueue structs. It also does a number of changes to the state machine: * The state machine will never ever stop in EXECUTING any more. Instead it will continue with the next queue (aka HORIZONTALQH) when the usb device returns USB_RET_ASYNC. * The state machine will stop processing when it figures it walks in circles (easy to figure now that we have a EHCIQueue struct for each QH we've processed). The bailout logic should not be needed any more. For now it is still in, but will assert() in case it triggers. * The state machine will just skip queues with a async USBPacket in flight. * The state machine will resume processing as soon as the async USBPacket is finished. The patch also takes care to flush the QH struct back to guest memory when needed, so we don't get stale data when (re-)loading it from guest memory in FETCHQH state. It also makes the writeback code to not touch the first three dwords of the QH struct as the EHCI must not write them. This actually fixes a bug where QH chaining changes (next ptr) by the linux ehci driver where overwritten by the emulated EHCI. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: add queue data structGerd Hoffmann
Add EHCIQueue struct, move the fields needed to track the queue state into that struct. Pass the new struct instead of ehci state down to functions which handle the queue state. Lot of variable references have changed due to that without an actual functional change. Replace fetch_addr with two variables, one for async and one for periodic schedule. Add functions to get and set the fetch address. Use EHCIQueue->usb_status (old name: EHCIState->exec_status) directly in ehci_execute_complete instead of passing around the status using a parameters and the return value. ehci_state_fetchqh returns a EHCIQueue struct now. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: trace buffer copyGerd Hoffmann

2011-06-14usb-ehci: improve mmio tracingGerd Hoffmann
Add a separate tracepoint to log how register values change in response to a mmio write. Especially useful for registers which have read-only or clear-on-write bits in them. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: trace port stateGerd Hoffmann
Trace usb port operations (attach, detach, reset), drop a few obsolete DPRINTF's. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: trace state machine changesGerd Hoffmann
Add functions to get and set the current state of the state machine, add tracepoints there to trace state transitions. Add support for traceing the queue heads and transfer descriptors as we look at them. Drop a few DPRINTFs and all DPRINTF_ST lines, they are obsolete now. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2011-06-14usb-ehci: trace mmio and usbstsGerd Hoffmann
This patch starts adding trace support to ehci. It traces updates of the status register (USBSTS), mmio access and controller reset. It also adds functions to set and clear status register bits and puts them in use everywhere. Some DPRINTF's are dropped in favor of the new tracepoints. No change in behavior. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2011-06-12virtio: correctly initialize vm_runningJason Wang
Current vm_running was not explicitly initialized and its value was changed by vm state notifier, this may confuse the virtio device being hotplugged such as virtio-net with vhost backend as it may think the vm was not running. Solve this by initialize this value explicitly in virtio_common_init(). Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-06-12virtio: guard against negative vq notifiesStefan Hajnoczi
The virtio_queue_notify() function checks that the virtqueue number is less than the maximum number of virtqueues. A signed comparison is used but the virtqueue number could be negative if a buggy or malicious guest is run. This results in memory accesses outside of the virtqueue array. It is risky doing input validation in common code instead of at the guest<->host boundary. Note that virtio_queue_set_addr(), virtio_queue_get_addr(), virtio_queue_get_num(), and many other virtio functions do *not* validate the virtqueue number argument. Instead of fixing the comparison in virtio_queue_notify(), move the comparison to the virtio bindings (just like VIRTIO_PCI_QUEUE_SEL) where we have a uint32_t value and can avoid ever calling into common virtio code if the virtqueue number is invalid.
