PEG VC0 VT-d Fetch Grant Count (PEGVC0GNTCNT)
The arbiter will continue to grant PEG VC0 VT-d fetch as long
as the grant count value in this field is greater than zero.
DMI VCp VT-d Fetch Grant Count (DMIVCPGNTCNT)
The arbiter will continue to grant DMI VCp VT-d fetch as long
as the grant count value in this field is greater than zero and
there is no higher priority VT-d fetch request. Arbitration will
switch to PEG VC0 VT-d fetch request if the grant count
corresponding to PEG VC0 VT-d fetch is greater than zero and
the VT-d fetch request corresponding to PEG VC0 stream is
available.
DMI VC0 VT-d Fetch Grant Count (DMIVC0GNTCNT)
The arbiter will continue to grant DMI VC0 VT-d fetch as long
as the grant count value in this field is greater than zero and
there is no higher priority VT-d fetch requests. Arbitration will
switch to DMI VCp or PEG VC0 VT-d fetch requests if the grant
count corresponding to those VT-d fetch is greater than zero
and the VT-d fetch requests corresponding to those streams
are available.
