[CLOSED][KERNEL][Affinity Kernel][OP5/5T][OOS/Custom][4.4.178][6 Apr] - OnePlus 5T ROMs, Kernels, Recoveries, & Other Dev

Introduction:
Affinity Kernel is a custom kernel based on the latest Stable Linux 4.4 release from kernel.org.
This kernel is developed with performance and great battery life in mind offering some goodies cherry-picked from other popular kernels such as Flash Kernel, ElementalX, blu_spark, Boeffla Kernel, Sultan Kernel and Franco Kernel.
The kernel is always up to date with mainline linux kernel and is regulary updated with the latest fixes.
The goal is to provide a butter smooth experience, simmilar to what you get with the latest Pixel devices.
Affinity Kernel is based on the official kernel source released by OnePlus.
Code:
/*
* Your warranty is not void (Thank you OnePlus!).
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this kernel
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

Installation:
Before you install the kernel, make sure you have
a backup of boot partition in case something goes wrong!
If you are coming from stock kernel:
Reboot into TWRP
Flash the Affinity Kernel.zip
Reboot
If you are coming from another custom kernel:
Reboot into TWRP
Dirty flash your rom or restore boot backup if you have any
Reboot recovery
Flash the Affinity Kernel.zip
Reboot
Updating:
Just flash the latest Affinity Kernel build over the previous one
Downloads:
{Mod edit}
On ROMs like Dirty Unicorns, WLAN won't work because the wlan module is required
to load on device initcall rather than late initcall like other ROMs do. There's a workaround for it but
it breaks WLAN on all ROMs that have the module built inline or the CAF way

I'll take this one

---

And this one

---

Thanks for the work, ill give it a try.
2 thing that bugs me are:
1- isnt restoring stock boot.img removes custom recovery and replaces it with stock one?(had that problem before)
2-is the kernel(pie) eas or hmp?

---

finally:good:

---

Thank you for your working on this kernel !
I have a problem with the least one. It's an eas kernel. My oneplus 5t restart it's os staying oneplus log more than 1 minute.Using r19 kernel spends about 30 seconds.
Is thit normal?
thank you.

1. Yes but it's better to do a backup of boot that has Magisk installed so you don't have to reflash TWRP
2. Since r20 it's EAS based

Haven't seen such behaviour yet, some users reported that it works perfectly on both 5 and 5T.

If I'm coming from a kernel like bluspark, I must flash the stock boot img first, correct? Where can I find this?

Kernel is good. Only thing i saw was cpu clocks wouldnt go down less than 800mhz and 500mhz.
Solid, liquid smooth, clean. For me it is better than RZ kernel

Minimum frequency is 518 and 806 because Qualcomm did it so people follow it

Hello
Are you using greenify or any other tweaks of that kind.
Thanks

Affinity Kernel r21 is up!
Since r21, Affinity Kernel is available for custom ROMs as well. Should work well with every ROM except of OmniROM and TreskMod (which is Pixel-like OmniROM)
because Omni has its own way of loading the WLAN module so WiFi might be most likely broken. Anyway, you may also notice that on some ROMs that have EAS baked in, Affinity Kernel
default settings are not getting applied. That's because the ROM has its own post boot init script that overwrites my settings, not a big deal.
Here's the changelog:
Upstreamed to Linux 4.4.176
Support for custom ROMs
Some touchups for init script
Added O3 GCC optimalization
Readahead improvements
A bunch of kgsl improvements (adreno driver)
devfreq improvements
