svn commit: r269615 - head/sys/dev/hptrr

John Baldwin jhb at FreeBSD.org
Tue Aug 5 23:47:27 UTC 2014


Author: jhb
Date: Tue Aug  5 23:47:26 2014
New Revision: 269615
URL: http://svnweb.freebsd.org/changeset/base/269615

Log:
  Various fixes to hptrr(4):
  - Use the existing vbus locks instead of Giant for the CAM sim lock.
  - Use callout(9) instead of timeout(9).
  - Mark the interrupt handler MPSAFE.
  - Don't attempt to pass data in the softc from probe() to attach().
  - Remove compat shims for FreeBSD versions older than 8.0.
