[CLOSED]Okitavera's Kernel for Mi 9 SE - v8.4
- Thread starter okitavera
- Start date
- Status
Hi guys, 7.0 kernel is compatible with full treble CrDroid 5.7? I have flashed it but phone stuck on MI logo...
I'm now on full-treble crDroid 5.7
The ROM sometimes are gets "confused" even though it's boot (in dmesg, the kernel and ROM is booting but doesn't get into the bootanimation).
You can try to reboot manual if you're stuck on the mi logo.

I see good potential for XenonHD ROM. It's very fast and light. It's still experimental so there's no fingerprint and a few bugs (actually I've only found 1 so far, nothing important) but there are also features working out of the box (like SIM management) that don't work on crDroid. Now I'm trying to install a custom kernel. Kowalski is having issues. Let's try Okita and see how it goes.

Yeah... both kernels are having issues with XenonHD for now. But I'm still keeping the ROM.
Currently I'm on crDroid, but I will try XenonHD tomorrow (already downloaded).
As far as I know, krasCGQ are using highly reworked kernel.
So definitely needs more adjustment on my side to get my kernel works on his ROM too

So, XenonHD needs to read high brightness status to get their LiveDisplay to be working (unlike crDroid).
And unfortunately, my kernel don't have that feature, so I'll add that in the next release.
*going back to crDroid again XD*

Hi guys, just announcing that "phone is starting"-loop issues on XenonHD has been resolved and I upload it as 7.0-r2 because it only quick-fixes.
It doesn't change anything on crDroid, so it's unnecessary to update if you're on crDroid

Just unpack the rom zip, get the boot.img and flash it via fastboot. Also don't forget to flash dtbo.img too.
Hi there, is there V6.1 has any problem with xiaomi.eu 9.8.15?
I still using 9.8.1 because last time using 9.8.8 no sound output.

Hello everyone. kernel has been updated to 7.1, and here's the changelogs
Changelog 7.1
- Updated Wi-Fi Driver to latest wlan-cld3.driver.lnx.2.0.3.r6-rel
- Follows google recommended kernel timing (HZ=300, better UI/UX performance with little-to-none power impact)
- Keep boosting time a little-bit longer on wake-up scenarios to get better unlocking performance.
- Tuned input boost value again to get better cpu efficiency.
- Properly set up/down ratelimit value on schedutil.
- Disable unused delay when updating backlight.
- Reduce more debugging feature and removed unused logging to reduce tiny overheads.
Download
Notes
I want to tell that Magisk Add-on is obsolete for now because it already merged into the kernel.zip as magisk service.
So, better to uninstall it to avoid conflicted kernel-parameters

Can it be used on MIUI?
Hi everyone!
We got another important updates from CAF on the security departments and CPU improvement
Changelog 7.2
- Merge update from CAF (TAG: LA.UM.7.8.r1-06900-SDM710.0)
- re-Introduce Exposure Adjustment (kernel-level DC Dimming)
Download
Tunable sysfs paths for DC-Dimming

# Minimal exposure that will be added when exposure adjustment is active

# Enable/disable exposure adjustment
/sys/devices/platform/soc/soc:qcom,dsi-display@18/msm_fb_ea_enable
# Maximum brightness threshold before exposure will be restored to the default state

Yeah, unfortunately...:crying: 2 kernels for aosp, 0 kernel for miui
But what can we do anyways, xiaomi doesn't give a damn about the source code of this device anymore.
So better to move forwards instead just waiting and stuck in the past.
Besides, I don't use MIUI anymore since the first crDroid release, so it would be time consuming to switch back and forth between different system.
Hello everyone, just mentioning that kernel has been updated
Changelog 7.3
- Updated to linux-stable v4.9.190
- Merge latest blu_schedutil updates from engstk (blu_spark kernel)
- Reset CFQ to default io scheduler
- Re-apply aligned cost-data from the legacy kernel
Notes
You can still use maple if you want, I decide to choose CFQ as the default because I think it's enough for daily usage
Also, about cost-data, it already present before at the miui version, I just forget to add it back when re-base the kernel.
The difference between previous cost-data and the v7.3 is : reduced slight battery cost, but with little-to-none performance regression (tested on UIBench, still pretty good ).

Intro
Okitavera's kernel is a custom kernel based on CAF Kernel with specific patches from Xiaomi.
Aims to provide stability, security, and other benefits from having a regular patches from Linux Stable, CAF, and Google.

- Exposure Adjustment (DC Dimming)
- AVB and SafetyNet bypassed
- KCAL, KLapse, Vibration control, and Sound control
- Check GitHub commits for more
- TL;DR : The best custom karamel (arguable)
Compatibility (v8.4)
- AOSP-based custom ROM (Pie)
- MIUI 10 and 11 (Stable or Weekly. Pie, NOT THE Q)
Downloads
Zach said this link should be bigger and as you can see he's right
Installation
- Backup your dtbo and boot partition.
- Flash the kernel.zip file via twrp

Xiaomi already publish the Mi A3 (or Mi CC9, CC9 Meitu, whatever you named it, Xiaomi) Kernel source code.
It basically uses the same base as ours, and after some hours of inspection,
me and @pengus77 got a few things from Mi A3 and Mi 9 source code that can be ported to fix several issues on this device (like the brightness, fod, etc)14Hello everyone!
Here's the update notes for v4.5
Changelogs
- Upstream kernel to 4.9.185 (android-linux-stable)
- Allow enforcing deepest cluster idle state selection
- Use power efficient workqueues on the vmstat and audio-kernel
- hardcode dirty_expire_centisecs to 30s (https://android-review.googlesource.com/c/platform/system/core/+/938362)
- Add IPA_RM12 and IPA_WS to the default block list (thanks to @pengus77 for more wakelock block list)
- Updated Goodix GT9886 firmware from MIUI Dev
- Cleaned-up unused touchscreen driver
Notes
I can't fix the short brightness bugs on MIUI Dev yet, so lmao yeah. - Merged patches from :
