This will definitly disable CPUidle - and you are using a perf-opencsd-v4.11 kernel?
George was mentioning that he tried the upstream linux kernel 4.11. I am trying to enable the ETM on the 4.9 kernel coming from the AOSP on top of a build from AOSP master. I know that I will be on my own there.
So let me do a smaller step: I will try to enable ETM on the hikey running Debian with the kernel from https://github.com/Linaro/OpenCSD/tree/perf-opencsd-master.
I think one thing should meantion is ARM-TF has another fixing: https://github.com/96boards-hikey/arm-trusted-firmware/commit/543f1db7fd7e0a...
If you are using latest boot images, you should have included this change int ARM-TF. This change is merged into ARM-TF at last year, but just ensure this is not a block issue at your side.
