Not yet, not sure what exactly to do ... will have a look if I can spare some time whis WE.

Hi Yank555! Finally getting about to post in your forum. Alas, distractions everywhere.
I've been really fond of your Slim builds, running them since early May without issue, until now. Back to stock temporarily as the 26.06.2015 build seems to be cause of my device overheating. I run the stock kernel as is and the only "mod" I use is a Layers theme. Apologies for not providing logs rather than suppositions. I understand little help can come from guessing. Just curious whether I'm the only one with the heating issue, 50°~C generally.

I was using active display without adaptive mode, color calibrating to a Night hue as I always run brightness at 0%; sans ambient or adaptive control for battery life. I'm usually screen on & multitasking more oft than not. While on the 26.06 build, I noticed my screen "rippling" black/grey tones neath the surface, and although screen tearing upon app switching is largely reduced if not altogether gone, the GPU is notably stressed so I have to shut off the device for it to cool.
BTW, I'm using Slim mini GApps and auto-restored a relatively condensed amount of user apps from Play. 127 total system/user apps while optimizing.

Some last question that will likely sound dense: How is it debugging mode is automatically enabled even though Dev Options, from my perspective, is not visible nor user activated from tapping the build number? Is it due to SELinux being set permissively by default? Sorry, I have security concerns, am awfully green with Linux, and been watching too many DefCon vids :shock: Trying to find the best means of securing against remote shell injections & unsolicited client - e.g. ssh, telnet - tunneling. Reduced to one device and I can't read/learn fast enough. Can't remember the 2-3 lines right now but I'm sure the "?? debugging=disable" + "setenforce=1" can be init scripted to persist across boots.
May flash your updated kernel with a few config changes. See if it helps. Thank you for sharing your work and time!

This depends on what runs at 50 degrees, CPU, battery ? Battery, would not be good, CPU, np, can easily handle more than that under load.

Could you try an older build that worked for you ? As I pretty don't see what could have been added between the 26th and the ~12th build (I'm not so sure about the dates, but those should be around the last 2 repo syncs where stuff would have been added by Slim, builds in between only have super minor changes, either a few gerrit picked functionalities or stuff coded myself.

This far more sounds like some app update gone wrong and causing high cpu load. Try using tools like 3C Toolbox to check what is causing CPU load and check if CPUs are constantly running at high freq.

Adaptive display has no impact on GPU stress, but going 'below 0' or very dark makes the display colors turn kind of pink or so, that's just like that, nothing bad that would cause damage.

Gapps are unrelated, esp. if you've used the same as before. If not, just try with the one that previously worked, I still use some from early april. 127 apps are not that many, me it's about double that :D

Because I set it to enabled in my boot.img, you need it to adb stuff when connected to usb, so unless you don't trust the PCs you're connecting your device to, there's no worries there, that thing is called 'USB debugging'.

SELinux is enforcing on bootup and set to permissive after boot, because some root apps don't work as expected when it's enforcing (granted app devs could fix that by fixing their app to properly work with enforcing, but well, there's one I use often so I can live with it).

Just reflash my kernel and change that setting in Aroma.

But you should be far more cautious with app permissions than with SELinux !

What you install and grant access to is far more likely to be a security issue in the first place than a permissive SELinux ! 3-4 Android versions back there was no SELinux at all and it was not an issue.

Also consider one last thing, SELinux is an NSA Security Extension, so security is a relative thing :D

Using security loopholes will not be avoided by SELinux status as that is using security flaws inside the system and by that can gain access to different SELinux profiles, this needs fixing in the sourcecode, and Android devices, esp. custom ROM are rather applying more than less such fixes. Ex. some 'big' kernel related issues are generally patched in 1-2 days by kernel devs, OEMs don't at all if your device doesn't get an update, or months later if it still does.

Telnet and such stuff would require daemons to be installed to actually answer to such remote connection requests ... but here we are back at square one, what you install is up to you, install dubious stuff, and you could be exposed even with SELinux being enforcing, esp. if it's root apps ;)

So the first responsible for security is the enduser, whatever you install and grant access and/or root to could stab you in the back ;)

Hey yank just stoping by to show some support!

Keep up the good work on your ROMs and kernels, your kernels especially kick serious butt!

Keep us updated if you have anything planned for Android M!

Yank my friend, i will be getting the nexus 5x when it releases.
I was wondering if you will be getting that phone as well?
Your kernel is still thus far the one to beat imo.

Still hesitating ... like the idea of 5.7" and 128Gb ... but hate to lose wireless charging ... dunno if 5X will still sport that.

If I feel really insane at some point might even go for both ... kind of Nexus addicted by now :D
