vr-mode on HiKey960

Hi guys.

I'm working for a client that would very much like to run the hikey960 in vr-mode in order to get minimum latency. In this product the latency from input to screen (HDMI) is the deal breaker.

This means that I need to run at least Android 8.0 (probably 8.1) with "TARGET_USES_HWC2" set. Apparently HWC2 contains some hardware-specific parts, but as far as I can tell, there is still no HWC2 available from HiSilicon.

I see that efforts are still focused on android-hikey-linaro-4.9, which is a bit disappointing. Backporting again are we?

Currently I am using tip on AOSP and android-hikey-linaro-4.9. What (and where) is the status for vr-mode with hw support for hiKey960? Anyone knows more about this?
