Currently if the Foundation model is running ARM Trusted Firmware then the kernel, which is configured to use spin tables, cannot start secondary processors or "power off" the simulation. After adding a couple of labels to the include file and splitting out the spin-table configuration into a header, we add a couple of new headers together with two new DTs (GICv2+PSCI and GICv3+PSCI). The new GICv3+PSCI DT has been boot tested, the remaining three (two of which existed prior to this patch) have been "tested" by decompiling the blobs and comparing them against a reference.How different are these from the ones hosted in [1] ?They look like they were either independently written or diverged a long time ago. The existing kernel DTs describe hardware absent from the ARM TF ones and vice versa.OK.quoted
With specific reference to PSCI it looks like my patches could perhaps be improved by adding idle-state support.Yes I know.You want a v3 with it added?
No, that's fine. I have pushed this already [1] with Mark's ack for now. We can add it later after some testing, not urgent. -- Regards, Sudeep [1] https://git.kernel.org/sudeep.holla/linux/h/for-next/juno -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
