Build 20180411 (April 11, 2018)

Catch up to voidKernel r10

r10 (08.04.2018):
Linux 3.10.103
Attempted to fix baseband issues with Magisk installed
Various minor kernel updates for LZ4 routines, BT, display etc.

Linux 3.18.104 from voidKernel commits.

Converted Adreno Idler to State Notifier.

Changed the initial GPU freq to 133MHz. This allows Adreno Idler to idle on the lowest frequency of 133MHz, instead of fluctuating between 216MHz - 320MHz.

Fixed Impulse governor.

Under the hood changes such as tuned tcp_westwood.

MiNT Kernel is now available to Stock ROM users!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] manan001:
Bro I would be happy if stock varient would have doubletap to wake.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] GamingDevilsCC:
I didn't remove it, so it should! However, you'd have to enable it with an app like Kernel Auditor or EX Kernel Manager.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] manan001:
Finally thank you very much i flashed it on stock. It does have double tap to wake. No issues with 5ghz WiFi connection. Activated impulse gov and some other tweak now will full charge and provides tou feedback. Thank you very much for providing kernel for stock.. hope you continue supporting t

For stock as well with eaqul custom kernel features.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] gougous3:
I've been investigating our device on the battery department and found yankactive and intelliactive governors to be the most balenced ones in terms of "battery performance ratio" (specially yankactive as it tends to use the lower frequencies of the spectrum). I seriously think that you should consider them for the next release.

Same goes to the Lazyplug CPU hotplugging driver which carries a different view of how hotplugging should be done, with modern efficient SoCs such as ours in mind.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Fractals:
this please more governors more freedom, also new hotplug will be good

I'm on a MetaPhoenix kernel right now. Do I have to dirty flash Stock ROM and then apply this kernel or is flashing stock boot img enough? Because right now, when I dirty flash this kernel over MetaPhoenix, it's not booting (I get past entering decryption PIN, but when the boot is ending, it restarts over and over)
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] oreo27:
So what's the installation procedure for this particular Kernel? Magisk then this? Or this then Magisk?

Edit - Flashed Magisk then this Kernel. Working now. Will test and provide feedback.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] siba01:
How sweep works? Thanks!

edit:

The ability to slide your finger from the back button to the recent apps button to turn the screen on, and swiping from the recent apps button to the back button to turn it off.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] radogost:
Try to reflask Magisk and than flash Mint. If still bootlooping I think you will need a wipe. And are you sure you've downloaded version for stock roms?
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] matcho13579:
Thanks for the suggestion, but it didn't help. I also tried to flash stock boot image, didn't help either. After that I went for a dirty flash of the stock factory image and now it's working just fine.

I assume that the possible cause of this is that the MetaPhoenix is (AFAIK) using different Wi-Fi module (and possibly other modules as well) which are incompatible with this kernel.

Whatever, now it's working :)
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] DeviceIK3:
Very good kernel. Thank you:good:
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] goofball2k:
You should always flash the stock kernel (or the whole rom if you don't have just the kernel) when switching in between kernels. Even though they may be based on the same sources, there are differences and I do believe most of the kernel dev's assume you're on the stock kernel before you flash their kernel.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] DeviceIK3:
Please add sound control.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] matcho13579:
True that.

I was basically expecting that I have to dirty flash ROM before switching kernels, I just wanted to know if the system would boot without it or not. So I went dirty flash kernel - flash stock boot before flashing Mint - dirty flash ROM before flashing Mint

Thanks for a bit of insight. Helpful stuff!
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Dasseem:
What might be the suitable IO scheduler for balanced battery- performance you reckon, trying Noop, read its good for flash based storage and battery life. Any other suggestions.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] manan001:
Its .105 kernel released hope to get update soon with new governs.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] gougous3:
IO schedulers have a very minimal impact on battery life and Noop, although a fine scheduler, can be caught lacking (performance wise) under tight situations so I'd recommend you to go with Maple or BFQ instead.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] Dasseem:
Thanks for the info, changed back to maple.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] GamingDevilsCC:
Was it a clean flash? How did you enable dt2w? (Through Kernel Auditor or?)

I'll be looking into this.

Yes ot was a clean flash inwas isong kwrnel auditor
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] methuselah:

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] matcho13579:
I'm having the same issue. I enabled DT2W in Kernel Adiutor (there are actually 2 options for DT2W in there - half and full - but both behave the same) and whenever I touch Recent Apps or Back capacitive button (HW ones, not SW), phone instantly wakes up. I had no such an issue with Meta Phoenix kernel, so you might try to check the implementation of DT2W in there (just a suggestion)
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] manan001:

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] caveiramix:
Great news!

Any preview on maximum configurable speeds?

The usual +200mhz on the CPU and +50mhz on the GPU seem a bit short.

I remember overclockable kernels on the original ZTE Blade, we could pick any speed, until it crashed, depending if the SOC was a good bin or a poor bin.

I had mine on 714Mhz, up from 600. 750Mhz would crash sometimes.

Anyway, thanks for your work.

Added GPU overclocking & correctly implement CPU overclocking with higher voltages? (These WILL use more battery. I do not recommend the higher voltages as overvolting uses more power, and reduces the lifespan of your device.)

Changed default governor to Relaxed. Relaxed is based on chill (which is based on conservative), and has been altered in order to achieve more gradual frequency boosting providing battery life benefits.

[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] gougous3:
I don't think that CPU overclocking would help much, at most, underclocking and/or undervolting instead. GPU overclocking, on the other hand, would be a more valuable feature considering that it's the weakest point of our SoC.

PegasusQ (or Nightmare) and lionheart CPU governors would be a nice addition as well. Same goes to the Zen and Maple IO schedulers.

And if you want to go down that route, CRC check deactivation, SHA256/SHA512 crypto algorithms, power efficient workqueues, HZ1000...
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] caveiramix:
I don't mean to get into your business but I guess you could take a look at Stormguard Kernel for the Redmi Note 4. It supports OC and it's also a snapdragon 625. And maybe some other stuff you can borrow too.
[Xiaomi Mi A1 ROMs, Kernels, Recoveries, & Other De] gougous3:
Overclock is not working, the frequencies are not being used somehow. The CPU either stays at 652 or 2016. I don't know if it is a reading problem but it stays at the oc frequencies for like a second on a limited number of cores.

And the new GPU frequencies are not being shown.

When you flash this kernel on slot a, you cannot update apps that has obb files in play store.. same issue with void, extreme and metaphoenix kernels. You cannot delete the obb file using third party file manager like es file explorer. However, you can update it by moving obb file outside of Android/obb folder. Moving it to external storage will not move the folder of the obb file, it will be copied. You can delete permanently the folder with obb file by using twrp file manager .

Issue does not occur when custom kernel was flashed on slot b.
