Has anyone noticed problems with uvideo(4) in recent snapshots?
The issue I'm seeing is reproducible with video(1) - just run it and
wait. After some seconds or minutes no new frames arrive and video(1)
is waiting on poll(2). Larger frame sizes seem to decrease the time
needed to achieve this state. No errors are logged at all.
Our in-house video monitoring has used a variety of uvideo(4) devices
for some years and this behaviour was not apparent up to 5.6 or in snaps
dated 2nd September (i386 & amd64).
Now, we see this behaviour on all tested i386 and amd64 systems running
recent snaps, regardless of whether our code is using mmap(2) or
read(2) and/or select(2) or poll(2) and with any uvideo(4) device.
We don't have any xhci(4) hardware, and everything works fine again
if we roll back to 5.6 release.
Two dmesg below, the first from the last snap we tried that is known
to work (a machine in production) and the second from my laptop
running Sunday's i386 snap which exhibits this behaviour.
Can anyone else confirm this?
Thanks,
Percy.
