From 68ffb01111500c769ceac055bdc2fb000322b2d7 Mon Sep 17 00:00:00 2001 From: Xenia Ragiadakou Date: Wed, 14 Aug 2013 06:33:56 +0300 Subject: xhci: trace debug statements related to ring expansion This patch defines a new trace event, which is called xhci_dbg_ring_expansion and belongs to the event class xhci_log_msg, and adds tracepoints that trace the debug messages associated with the expansion of endpoint ring when there is not enough space allocated to hold all pending TRBs.
