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*

I was struggling to find a working version of anx camera and even bsg was having issues with ultra wide mode, and I'm happy to say that, after installing okita kernel, all issues are gone. Now I can use both gcam and anx camera without any problem. :)

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I want to tell that Magisk Add-on is obsolete for now because it already merged into the kernel.zip as magisk service.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 :eek:

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
Code:
# Minimal exposure that will be added when exposure adjustment is active
/sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_min

# Enable/disable exposure adjustment
/sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_enable

# Maximum brightness threshold before exposure will be restored to the default state
/sys/devices/platform/soc/soc:qcom,[email protected]/msm_fb_ea_elvss_off_treshold

:crying: 2 kernels for aosp, 0 kernel for miui :rolleyes:
Yeah, unfortunately...

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 :eek:

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 :eek:
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 :eek: ).

    Breaking news.

    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) :)

    Good Bye :D

    Hello everyone!
    Unfortunately, I have to stop the development for Mi 9 SE due to device change

    The kernel sources for this device still available at my GitHub page if you want to fork or even just looking around.

    Thanks for all the support given and see you later :)
