    firewire: ohci: pass correct iso xmit timestamps to core · 31769cef
    Jay Fenlason authored
    Here is the final set of patches I used to get ffado to work with the
    new firewire stack.  With these patches, I was able to start ardour
    and record from and playback to my PreSonus Inspire1394 from a
    (mostly) Fedora 12 system.

    Until now, firewire-ohci exposed only the transmit cycle of the last
    transmitted packet at each isochronous transmit complete event.  This
    made it impossible for FFADO (FireWire audio drivers in userspace) to
    synchronize audio-out streams.  The fix is to store the timestamp of
    each packet in the iso xmit event.  As a bonus, the transfer status is
    stored too.
