    [PATCH] UHCI: Reimplement FSBR · 84afddd7
    Alan Stern authored
    This patch (as683) re-implements Full-Speed Bandwidth Reclamation (FSBR)
    properly.  It keeps track of which endpoint queues have advanced, and
    when none have advanced for a sufficiently long time, FSBR is turned
    off.  The next TD on each of the non-moving queues is modified to
    generate an interrupt on completion, so that FSBR can be re-enabled as
    soon as the hardware starts to make some progress.
