Hi Arnaldo, Will,

are there any comments on this series?


Hi Ganapatrao,

Is it possible to have vendor sub-folder in tools/perf/pmu-events/arch/arm64
folder (like arm64 device tree files)? We (HiSilicon) want to add support
for our hip08 SoC, and I don't think "hip08" or "<internal code name for
core>" are good arch sub-folder names.

at present the directory structure is in-line with as done for x86 and powerpc.
there can be separate patchset to have directory hierarchy as
suggested by you, if every one agrees on it!

Fine.

BTW, Shaokun has a json file for our hip08 platform waiting, based on this current patchset. We can send it now if anyone wants to see another arm64 json.

Much appreciated,
John



I am not sure if this way discussed before, but the changelog does not
mention it. And I think that we had the same location for thunderx2 in v1
series.

We should also consider that in theory the events could change per SoC using
the same custom ARMv8 custom implementation.

Thanks,
John
