Hi Mike, Suzuki
[...]
Please look at the CoreSight components specification 3.0 (ARM IHI
0029E) Section B2.1.2 which describes the Unique Component Identifier
(UCI).
As mentioned above this consists of a combination of bits from
multiple registers, including PIDR4.
Ok got it now, thanks for clearing the doubt. I will go ahead with
this method to identify QCOM impl and post a patch.
Looking some more into this, since we have this limitation only on
specific replicator on very few QCOM SoCs, rather than having a blanket
workaround for all QCOM, we were thinking it would be better to have
this workaround based on a firmware property something like
"qcom,replicator-loses-context" for those replicators with this
limitation and then set the drvdata->check_idfilter_val based on
this property.
Thanks,
Sai
