From 84afddd7ac58adad00cb0e50d0af25fcf825668b Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 12 May 2006 11:35:45 -0400 Subject: [PATCH] UHCI: Reimplement FSBR 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.
