Question about hotplugging: Is it really intentionally disabled.
Manually disabling a single core in Kernel Adiutor works just fine, why are they kept on all the time?

Hotplugging is unnecessary from a power saving perspective. The cores don't need to be offline to go onto a low power state.

But the big.little architecture depends on extremely low latency. Hotplugging just slows things down with no benefit.

Offlining cores with KA will only be temporary, eventually the thermal daemon or something else in the system will put those cores back online. Just like with hexacore mode in my app.

I have no idea what's going on with he reboots. Enough people have reported them that I have investigated, but I've come up with nothing. And as I've mentioned, my wife's 5x is running completely stable. She ran for 20 days straight without restarting the phone.

Other than Google's changes, I haven't made any changes to the kernel for quite some time and everything was definitely stable up until March. I suspect something with the March update caused a problem, but only for some people. Not sure if it's hardware, software, kernel or system.
It's not happening on April update so you might want to take credit for it. Just sayin'.

It seems most of the reboots have been on PA, it might have been ROM related, but the April update seems to have helped

I've had no issues at all with your kernel. Been on stock for quite a while. Switched over to pure nexus about a week ago. I'm not having any issues these people are having. Maybe they're flashing over an already custom kernel? I backed up stock on mine and restore boot.IMG each time I flash a new ROM/kernel.

Great work though. Definitely my favorite

Nope. Stock rom, stock kernel.. random reboot. Stock rom, 1.11.. random reboot, PN stock kernel and 1.11 random reboot. Now it didn't happen often but it happened perhaps once or twice a week or maybe more. But on the April update I've not had a single reboot no matter the rom, kernel or activity. Flar's wife didn't have reboots on the March update either so it's probably something in the chipset that make it bonkers? I have no idea but I certainly agree, great kernel.

@flar2 Is it feasible implement " Double tap to show ambient display"?

Sent from my Nexus 5X using Tapatalk
Wouldn't that be similar to double tap to wake in terms of battery drain?

It would still have the same drain as regular doubletap. The other problem is that ambient display is handled outside the kernel. I think you would have to hack the sensor library, which is a closed binary, to modify it.

What does wake function timeout do? When does it disable the wake gesture?

Sent from my Nexus 5X using Tapatalk
I'll take a stab at it. I believe the timeout is when no further input will be detected. The shorter the time period, the less battery drain. There is also an option, at least the last time I looked at it, the if you turn off the screen via the power button the dt2w function is disabled immediately.
