[Q] Any custom 5.1.x rom/kernel without throttling defect?

The title speaks for itself, are all the current 5.1 custom roms/kernels (non stock based) affected by the same throttling bug that allows only one core's frequency to be lowered instead of all four? It happens at least with cm12.1 (kernel) based roms.

[DEV request] Undervolt capable kernel

I've been a lurker on XDA for 6 years, but this is the first post, so I can't post in the development section. Is anyone interested in releasing a tweaked stock kernel that can be undervolted? That's free battery life improvements and cooler temperatures on the table that we aren't utilizing. Thanks.

http://forum.xda-developers.com/moto-maxx/development/kernel-bhb27-kernel-t3207526
or you're asking for another one?

Sorry, should have specified that I'm looking for a kernel compatible with the stock ROM, or in my case, Computerfreek's unlocked ROM for the XT1254.

^^ i second that motion, ive tried flashing BH's kernel on CF's rom and it does not work.

@baybutcher27 did Motorola release the source for their kernel?

yes.
https://github.com/MotorolaMobilityLLC/kernel-msm/tree/lollipop-5.1.1-release-quark
the job is not easy to make adaptation to stock kernel is need the kernel source for that ROM that one is for su44 but I don't believed that is 100% update in relation to the kernel that is on Su 44, some tings are odd to me when I look to the source but it must work. we can make that one to work on custom ROM, but to make it work on stock, is need a dev that have a XT1254 and are on verizon network and a lot of time.
Most change that I make work on custom can be ported to the stock kernel, so if a dev can do this it just need to check to my or any other msm or apq8084 device nexus 6, and samsung device that have apq8084 variant note 4 and S5 maybe others.
I can make my kernel boot on xt1225 5.0.2 stock ROM, but many tings don't work of course that kernel source is not made to xt1225 stock ROM but I can make it boot, so if a dev has a xt1254 and are on verizon may have more luck.

CM13 Snapshot vs CM14.1 Nightly

In your opinion, do you prefer CM13 (or marshmallow based roms) or CM14.1 (or nougat based roms) more? Which is better in terms of 1) performance/smoothness, 2) battery, and 3) features? Also, what kernel do you recommend with each version?

Kali Nethunter Quark/Droid Turbo

Has there been a ROM developed that is compatible with QUARK? Been trying a bunch of different ROM options and settled on Nethunter. Any and all help is appreciated.

There's tons of ROMs for Quark for like the past three years. Very confused by your question. Most are listed over in the OTHER Quark forum, because these forums were split about two months before the Droid Turbo got bootloader unlock. And the Droid Turbo users were tired of seeing active dev work they couldn't participate in. Even after bootloader unlock, most dev work was still posted over there -- with some here. With one exception (noted below) all these ROMs are compatible with all the Quarks.
Droid Turbo XT1254
Moto Turbo XT1225
U.S. Moto Maxx XT1250 (exact same device, same FCC ID as the Droid Turbo but sold by other carriers in the U.S. Verizon wanted to PRETEND they had an "exclusive" when they didn't.)
Moto Maxx XT1225 (sold in Latin American countries and India but has all the AT&T LTE bands)

One update: AOSP ROM has a new maintainer, @Hlcpereira, who is taking on that duty in addition to the Viper OS ROM. He's also started a fresh thread for that ROM. Updated link below.
We have SEVEN Nougat ROMS supported by maintainers compatible with all Moto Quarks (XT1254, XT1225, XT1250). And with the Quark Multi-ROM tool by prolific dev @bhb27 , you can try out more than one.

If you install them, they will still work, but there will be no future development. @bhb27 last gave an update to RR 6.X in March 2017, but you can still run it fairly safely if you install his up-to-date standalone custom kernel along with it. I was on RR 6.X until recently, and my wife's XT1225 is still on it. However, if you want Blueborne protection you need a current Nougat ROM with at least September 2017 safety patch.

That list above is in no particular order, except 6.X RR has the most recent update.
_________________________
These two below are listed separately because they are mostly for the XT1254/XT1250, while the ones above are for ALL Quarks (XT1254, XT1225, XT1250). @iiWoodstocK's ROM will run on any Quark, but it's just stock Motorola Brazilian XT1225 Marshmallow ROM with CMDA build prop added and @bhb27 custom kernel so wi-fi worked... No other tweaks. So, the only advantage to XT1225 users is it can be installed via TWRP. For XT1254/XT1250 users however for MONTHS it was the ONLY stock Marshmallow ROM available which would run on their phones. There was no Verizon VoLTE, but it had everything else.
MARSHMALLOW - OTHER:
@computerfreek274 has now released a Marshmallow ROM for the Droid Turbo XT1254 (it will also work for the XT1250, of course) based on the Verizon's belated Marshmallow firmware. He has debloated it, tweaked it. It has Verizon voicemail app, Verizon VoLTE (only works on Verizon), Verizon Wi-Fi calling (only works on Verizon), some volume boost, and battery saving tweaks. It is still under development -- unlike those Marshmallow ROMs above. There's also a "non-Verizon" version (without Verizon apps) of his ROM posted in that thread, but again it's just for the XT1254 (and XT1250) as it is based on Verizon's Droid Turbo stock firmware. Do NOT try to install it on an XT1225!

You can also install a Marshmallow stock ROM released by Motorola for the Brazilian Quark. @iiWoodstocK adapted it so it runs on ANY Quark, including the XT1254 Droid Turbo or XT1250 U.S. Moto Maxx (clone of the XT1254). It will use YOUR radio, whatever you have installed.

I didn't include it in the Marshmallow list above, because while technically it is a custom ROM, the only "customization" was to allow it to be flashed via TWRP and to allow it to be used on ALL Quarks: XT1254/XT1250/XT1225. Otherwise, it's pure Motorola Marshmallow stock which was officially released for a Quark phone.

Custom Kernel to increase battery life with original or GPE firmware?

Hello,
I have 2 HTC M7 with slim rom 7.1.2. build.2.0 and GAPPS pico. One of them is S-OFF with GPE firmware (6.04.1700.19). Clean install via TWRP, no further apps installed, so far. Both phones lose about 1.5%/h battery in stand-by - thus more than twofold compared to stock firmware+rom, before.
Can anyone tell me, what are the reasons for this higher battery consumption? Forums on custom roms mostly give information that battery consumption will be improved with custom rom.
I think of installing a custom kernel to improve battery life. Where can I find a compatible kernel to my custom rom and different firmwares? Or would it be sufficient to install a kernel tweaking tool (eg. kernel toolkit) to adjust settings for the current kernel? In Slim Rom, kernel information is 3.4.113-g9776217([email protected]) (gcc version 4.9 20150123) prerelease).
Thank you very much.

There is only one custom kernel for N Roms and this one doesnt have any improvment for battery or kernel tweaks, there is no way to extend the battery life except for dont use gapps. You will get the best battery life with gpe rom and elementalx kernel, but this is android 5.1, but this is the only way to underclock the cpu/gpu with all adroid versions higher like 6.x undervolting allways caused system instability. If you want to have a bettter battery life with android 6.x or higher the only way is to use nanomod microg (or the new name of this magisk module "nanodroid") instead of gapps. It will replace everything what google services do for you with opensource programms, you will be able to use your google account as usuall and being able to use the play store but without the high battery drain gapps are causing. If you want to know more about this you can read everything here https://forum.xda-developers.com/htc-one/help/tips-standby-time-t3661814

Thank you, I will try it. As I have seen this should still allow for using paid apps from play store if needed.
Though I don't understand why battery consumption with custom rom nougat is that higher than with stock rom lollipop. I also tried clean installing custom rom without any GAPPS, but battery drain in standby and with flight mode was still considerably higher (0.9%/h) than in stock rom incl. Google services and no flight mode (0.5%/h)?

Hm, now I have
- 1 M7 S-off, GPE firmware, Slim rom 7.1.2 build 2.0 + microG
- 1 M7 S-on, HTC firmware, Slim rom 7.1.2 build 2.0 + Gapps pico,
- 1 M7 S-on, HTC firmware, HTC stock rom.
So far, no further apps running, GPS, NFC and bluetooth deactivated. Hourly battery drain in stand-by is almost identical on phones with slim rom (1.5% per hour) - and more than twofold compared to stock rom (0.6% per hour). Since I have tried several custom roms before, I noticed that other Android M+N roms (lineage, AICP, xenon, tesla) all have battery drain comparable to slim rom.
Seems to me that there is no way to get low standby battery consumption with a custom rom Android M/N. Within a 16 hour day I loose about 15 percent battery more than with stock rom Android L only due to standby. Am I the only one with this issue (or the only one interested in this)?

If you have identical battery drain on both devices with slim rom (one with gapps one with microG) there is definitivly something wrong on your side. Every user i have ever read from using microG said the same about better battery (about 10% more at the end of a day compared to same rom with gapps). And for me it was the same, with aicp and gapps i had only 15% at the end of a day, with aicp and microG i had about 25% left.
