New Revision: 326152
URL: https://svnweb.freebsd.org/changeset/base/326152

Log:
  amd-vi: fix and extend definition of Command and Event Status Register (0x2020)
  
  The defined bits are the lower bits, not the higher ones.
  
  Also, the specification has been extended to define bits 0:18 and they
  all could potentially be interesting to us, so extend the width of the
  field accordingly.
