Nice work, I want to try your patches. But I have only one machine with
debug capability, I think I can use it as debug target. Can I use another
machine with usb 3.0 but no debug capability as the debug host?
BTW, I hacked a cable according to usb 3 s
ioctl to return all device capabilities.
Fix PATCH V1 bug: not waking sleepers on disconnect.
Correct sparse warnings.

I have a .config with CONFIG_PM disabled. I get the following
whenever compiling the xhci driver:
drivers/usb/host/xhci-pci.c:192:13: warning: âxhci_pme_quirkâ defined but
not used [-Wunused-function]
Looks like we just need to move xhci_pme_quirk() to be underneath

Out of curiosity, do you know why one must poll for output (rather than for
input)?
JDoes "writability" precisely mean that there's at least one
user-submitted URB that can now be reaped?

Can anyone point me to documentation that formally describes how it works?

I used usb cdrom emulation to play video dvd for my daughter, but I got below
error:
[dave@darkstar tmp]$ cat /mnt/sr1/VIDEO_TS/VTS_01_5.VOB >/dev/null
cat: /mnt/sr1/VIDEO_TS/VTS_01_5.VOB: Input/output error

all of them are arbitrarily
blocked. That lets each thread safely unblock each signal it cares about. So, I
aghree, there's no bug - just a bit of memory loss on my part.

- in our
case, that's only one of them - shouldn't the handling revert to the default
for that signal? Isn't it wrong that, when there are no signalfd file
descriptors open for a given signal, the signal still seems to stay pending
within the signalfd mechanism?
--
Dave Mielke
n the previous attempt is
delivered. Flushing the signalfd file descriptor before closing it resolves the
problem. I guess we all know a little bit more about signalfd now. :-_) Thank
you for bearing with me.

Just like the siginfo data has fields that must be left over from somewhere
else, might it be that the user urb is copied, without clearing the signr

What might it mean that ssi_addr is NULL? Is a non-user urb ever submitted
underneath that might be causing the notification?

The entire application (brltty, if you're curious) is a set of event handlers
that come and go as needed. The signalfd notification is appearing on the very
first call to poll() after the urb is submitted.
