Hi George,

Looks like that ARM-TF patch was precisely what I was missing. :)
When I set the bits that patch sets, I can now get Hikey to fully boot with OpenCSD's Linux branch 4.11+ETMs, and can capture perf traces like so: perf record -e cs_etm/@f6404000.etr/u --per-thread -- ./foo
Could you please send a patch or more explanations with what is needed? I still have not figured out how to use the arm-tf patch that Leo pointed out.
Thanks, Sebastian
