Using the (legacy) qemu-kvm git master repository which does not have these patches (not sure which patch is causing assert specifically yet). Using a Logitech QuickCam Pro 9000 and starting a Windows VM will crash when the device is detected. Crash in log: qemu-kvm: /builddir/build/BUILD/qemu-kvm-1.2.0/hw/usb/hcd-ehci.c:2018: ehci_state_fetchqtd: Assertion `0' failed. 2012-09-19 15:36:04.011+0000: shutting down I only came to this conclusion after noticing at least in Fedora that 1.2.0-rc1 did not have any of the EHCI and USB redirection patches added. So by using the -rc1 spec file w/o the patches I can use Qemu/KVM successfully w/ webcam and no asserts. I have also installed: usbredir-0.5-1.fc18.x86_64 Thanks, Shawn. ^ permalink raw reply [flat|nested] 31+ messages in thread

This is caused by a recent change to fix a memory leak inside the ehci codes interrupt ep handling, together with: // TODO Windows does not seem to ever set the MULT field The above windows bug (not setting the MULT field is against the spec), causes ehci_state_execute() to exit without even executing the packet once, which leaves the packet in an uninitialized state. And when fetchqtd then later on sees there already is a packet in flight for the ep queue, it barfs on it not being initialized. I already had looking into the windows MULT issue on my to do, so I've just bumped it to the top :) Unfortunately I cannot reproduce what you are seeing even though I do have a logitech pro 9000 to test with myself. I've tried with both a 32 bits windows XP as a 32 bits windows 7, what guest OS are you running? Besides not being able to reproduce I've written what I believe is a fix for this. I'll post that to the list right after this mail. Can you test qemu build with the fix added? And please also set the usb-redir device's debug parameter to 4 and send me the generated qemu log ? This will allow me to see not only the assert is gone but that also the interrupt ep is working properly... To set the debug to 4 use ie: -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,debug=4 Do this for all the usb-redir devices on your cmdline!

When you say disable the usb-redirection device, do you mean removing the host redirection, and selecting the cam for redirection in a spice client (ie remote-viewer) instead, or... ? Can you please try, disabling host-redirection, then connecting to the vm with remote-viewer and then selecting the cam from remote-viewers UI?

If I keep usb-host and add usb-redirection it shows those errors. Your patch however did fix using host-usb alone. I don't have a setup that can let me use usb-redirection unfortunately.

Why not? Looking at your qemu cmdline you are using spice. Hmm, I guesss you may want to keep the device redirected when no client is connected? Anyway, if you could remove the host-redirection temporarily and try with spice usb-redir and collect logs that would be great. If you don't have time for that, that is ok too, then I'll consider this issue resolved. Regards, Hans ^ permalink raw reply [flat|nested] 31+ messages in thread

I assume usb-redirection for devices *not* on the same machine as the running VM?

I consider the issue resolved solely on usb-host issue vs any regressions with usb-redirection itself which I never used/tried. However, if someone can point out how you can test this, I can do this also. Thanks, Shawn. > > Regards, > > Hans ^ permalink raw reply [flat|nested] 31+ messages in thread

You are running Fedora-18, right? Can you please try using either kernel 3.6.0-0.rc6.git0.1.fc18.x86_64 or an F-17 kernel, most Fedora 18 kernels have various debugging options enabled causing significant additional latencies in the network stack.

Hmm, this likely is caused by too high latencies in your system, which are caused in turn I believe by you running an F-18 kernel which has various debugging options enabled inside the kernel which can cause significant latencies. I've spend 1.5 days tracing this very same issue down in the past. So please first of all make sure that you're running a kernel without debugging options enabled, either the latest F-18 build from koji: http://koji.fedoraproject.org/koji/buildinfo?buildID=358570 or an F-17 kernel, almost all the F-18 "rc" kernels have debugging enabled and thus cause significant latency issues. If you can reproduce this with a kernel without the debugging options, then we can investigate this further. Regards, Hans ^ permalink raw reply [flat|nested] 31+ messages in thread

By changing the kernel, don't you just make the issue harder to reproduce? I mean Linux isn't real-time so any kernel can show latency spikes and it's a show-stopper if iso transfers stall instead of just dropping some packets. There will always be a race between the call to USBDEVFS_DISCARDURB and the URB completing. IMHO the handling in usb_host_stop_n_free_iso() is buggy. How about dropping the "killed" and "free" variables and calling async_complete() and g_free() unconditionally? Johannes ^ permalink raw reply [flat|nested] 31+ messages in thread

This race is well known already handled correctly, the real problem is the "ehci warning: guest updated active QH" message, which most likely indicates that the guest has hit the doorbell (IAAD) in the EHCI controller, and then has not gotten an IAA interrupt within a certain amount of time triggering its IAAD watchdog (some real EHCI hardware is broken wrt delivering IAA interrupt) causing us to not see an unlinked qh as unlinked, and then later on triggering the "warning: guest updated active QH" message. This is unavoidable when we get too large latencies, the ehci hardware simple was not designed to be virtualized, anything but actually.

OK, thanks for this explanation. I haven't much clue about qemu but isn't the issue that qemu delivers timer irqs to the guest (for EHCI_HRTIMER_IAA_WATCHDOG) while failing to handle the IAAD -> IAA interrupt generation? (via qemu_bh_schedule -> ehci_advance_async_state -> ehci_raise_irq, why does ehci_raise_irq() not call ehci_update_irq() for USBSTS_IAA?) If that cannot be fixed, have you tried talking to the Linux EHCI driver maintainer if the EHCI_HRTIMER_IAA_WATCHDOG timeout (10ms) can be increased or skipped entirely for non-broken hw? (Linux commit 26f953fd884ea4879 suggests it's only for VIA chips) Thanks, Johannes ^ permalink raw reply [flat|nested] 31+ messages in thread

We need to throttle the interrupt generation inside ehci both per the spec, and because otherwise we may trigger: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=361aabf395e4a23cf554cf4ec0c0c6963b8beb01 Which is present in all but the very latest linux kernels. > If that cannot be fixed, have you tried talking to the Linux > EHCI driver maintainer if the EHCI_HRTIMER_IAA_WATCHDOG > timeout (10ms) can be increased or skipped entirely for non-broken hw? > (Linux commit 26f953fd884ea4879 suggests it's only for VIA chips) AFAIK Shawn is using a windows guest, so the fact that he is seeing the "ehci warning: guest updated active QH" warning, suggests that windows is using a watchdog too, also the messages about cancelling the isoc stream suggest that windows is actively stopping the stream from the webcam, at which point there is little the redir code can do to recover. This could be caused by timeouts caused by the latency spikes from the debug kernel... We do our best to make the whole usb-redir code and ehci emulation as proof as possible against latency spikes, and some of the patches from my latest patchset may help there, but in the end, esp. for isoc devices, the code will always be sensitive to too large latencies.

OK, I read up on the EHCI interrupt threshold and found how ehci_frame_timer() calls ehci_commit_irq(). I agree it is hard to fix. I wonder if it would be sufficient if qemu would guarantee ehci_frame_timer() runs before sending the timer irq that triggers the IAA timeout, but I guess it depends on what the guest processes first. I also wonder if this is not a generic problem for all emulated hw if the driver uses some timeout? Thanks Johannes ^ permalink raw reply [flat|nested] 31+ messages in thread

Yes it likely is, because the emulated timer interrupt will try to make up for time lost when the vm was not running (in either hypervisor or guest mode), while as hw emulation code which has been pre-empted for what ever reason my simply need some more actual running time before it can complete the task as hand, at which point the timeout will trigger sooner then the hw emulation can handle the task ... Note that with the EHCI emulation we also can have the 2 (guest and hw-emulation time) get out of sync in the other way. When we got behind in processing frames on the periodic schedule compared to "real-time" we would catch up too fast, causing the guest to see large jumps in the frindex register, which it does not like. So all of this really is a precarious balancing act, and to get back to the subject of the thread, the latency spikes some of the kernels debugging options can cause, can upset the balance...
