SysBus EHCI was introduced in a hurry before 1.3 Soft Freeze. To use QOM casts in place of DO_UPCAST() / FROM_SYSBUS(), we need an identifying type. Introduce generic abstract base types for PCI and SysBus EHCI to allow multiple types to access the shared fields. While at it, move the state structs being amended with macros to the header file so that they can be embedded. The VMSTATE_PCI_DEVICE() macro does not play nice with the QOM parent_obj naming convention, so defer that cleanup.

Due to the way devices are addressed with xhci (done by hardware, not the guest os) there is no packet when invoking the set-address control request. Create a dummy packet in that case to avoid null pointer dereferences. Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

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.

Before this patch uhci would process an unlimited amount of frames when behind on schedule, by setting the timer to a time already past, causing the timer subsys to immediately recall the frame_timer function gain. This would cause invalid cancellations of bulk queues when the catching up processed more then 32 frames at a moment when the bulk qh was temporarily unlinked (which the Linux uhci driver does). This patch fixes this by processing maximum 16 frames in one go, and always setting the timer one ms later, making the code behave more like the ehci code.

Re-arrange how we process frames / increase frnum / report pending interrupts, to avoid a 1 ms delay in interrupt reporting to the guest. This increases the packet throughput for cases where the guest submits a single packet, then waits for its completion then re-submits from 500 pkts / sec to 1000 pkts / sec. This impacts for example the use of redirected / virtual usb to serial convertors. Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

I tried lowering the time between raising an interrupt and rescanning the async schedule to see if the guest has queued a new transfer before, but that did not have any positive effect. I now believe the cause for this is that lowering this time made it more likely to hit the 1 ms interrupt threshold penalty for the next packet, as described in my "ehci: Use uframe precision for interrupt threshold checking" commit. Now that we do interrupt threshold handling with uframe precision, futher lowering this time from .5 to .25 ms gives an extra 15% improvement in speed (MB/s) reading from a simple USB-2.0 thumb-drive. While at it also properly set the int_req_by_async flag for short packet completions. Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Before this patch, the following could happen: 1) Transfer completes, raises interrupt 2) .5 ms later we check if the guest has queued up any new transfers 3) We find and execute a new transfer 4) .2 ms later the new transfer completes 5) We re-run our frame_timer to write back the completion, but less then 1 ms has passed since our last run, so frindex is not changed, so the interrupt threshold code delays the interrupt 6) 1 ms from the re-run our frame-timer runs again and finally delivers the interrupt This leads to unnecessary large delays of interrupts, this code fixes this by changing frindex to uframe precision and using that for interrupt threshold control, making the interrupt fire at step 5 for guest which have low interrupt threshold settings (like Linux). Note that the guest still sees the frindex move in steps of 8 for migration compatibility. This boosts Linux read speed of a simple cheap USB thumb drive by 6 %. Changes in v2: -Make the guest see frindex move in steps of 8 by modifying ehci_opreg_read, rather then using a shadow variable Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

ehci_fill_queue assumes that there is a one on one relationship between an ep and a qh, this patch adds a check to ensure this. Note I don't expect this to ever trigger, this is just something I noticed the guest might do while working on other stuff. The only way this check can trigger is if a guest mixes in and out qtd-s in a single qh for a non control ep.

This is not allowed, except for clearing active on cancellation, so don't warn when the new token does not have its active bit set. This unifies the cancellation path for modified qtd-s, and prepares ehci_verify_qtd to be used ad an extra check inside ehci_writeback_async_complete_packet().

The spice_server pointer is a global variable and vm_change_state_handler() therefore does not use its opaque parameter. The vm change state handler is added with a pointer to the spice_server pointer. This is useless and we probably would not want 2 levels of pointers.
