Hi,
It would appear here that normal coresight funnels appear between tpdm
and tpda devices. This is contrary to my understanding of your
hardware and the descriptions and conversations we had in patch 00/10
in this set.
trace path appears to be
tpdm_mm => funnel at 6c0b000 => funnel at 6c2d000 => tpda at 6004000 =>
funnel at 6005000 => rest of ATB
The documentation states that the TPDA is responsible for for
funneling and packetising - so why do we have extra funnels?
I have no way of knowing if that topology is right or wrong. Are the
funnels between tpdm and tpda actual coresight funnels, a component
that is register compatible with CS funnels but designed for the TPDM
/ TPDA transport, or the funnels are being used, but without driving
ATID from the sources.
It is difficult to review this set without better information on the
hardware represented.
Regards
Mike
