Author: hselasky Date: Mon Oct 6 06:01:46 2014 New Revision: 272589 URL: https://svnweb.freebsd.org/changeset/base/272589 Log: MFC r272349, r272422 and r272479: - Fix XHCI driver for devices which have more than 15 physical root HUB ports. The current bitmap array was too small to hold more than 16 bits and would at some point toggle the context size, which then would trigger an enumeration fault and cause a fallback to the EHCI companion controller, if any. - Make sure we always set the maximum number of valid contexts. - Set default cycle state in case of early interrupts.
