Okitavera's Kernel for Mi 9 SE - v8.4

[okitavera]

I tried with 84hz, the animations and transitions between apps is stuttering, it's like the phone itself can't keep up with it.
Turning down to 74hz, that problem are still happening.

Also I tried with 64hz, it works quite well. but the battery consumption isn't normal.

Can you write a guide to how mod the dtbo img for change display HZ? We are searching to do this on Mi9 to try lower HZ like 75 for example. Ask this because 84 cause a green tint really awful. Thanks

I don't directly modify it, but building from the kernel source.
It already explained in https://source.android.com/devices/architecture/dto/partitions#mkdtimg

Hello everyone!

Here's the update notes for v3.0

Changelogs

- Remove xiaomi's memory management and restore it to the default Linux/CAF changes (zram, vmalloc, lmk).
- Remove unused xiaomi's package runtime info, manual watchdog invocation and other minor changes.
- Now this kernel uses compiled dtbo.img from the source code itself, thanks to @faust93 for the patch.
- Merged Qualcomm Atheros WLAN modules (LA.UM.7.8.r4-01000-SDM710.0).
- More tweaks on the CPU big cluster battery costs.
- Reduced the GPU idle timeout for earlier low-power state.

Just tried it with the latest revolutionOS rom and it is not fully compatible mate ! This kernel breaks fingerprint sensor on the rom unfortunately.

Revolution OS is based on the same dev version of xiaomi.eu. When and if it will work on one,it will work also on the other.

Read topic please, new roms after 9.5.30 breaks fingerprint with okita kernel, because Xiaomi developer not updated kernel source on GitHub.

Alright,but thx for new build

Well, technically it works on miui dev as well. Just need to be enabled by hands first:
echo 1 > /sys/devices/virtual/touch/tp_dev/fod_status

Wait, so everytime the phone's boot, we need to re-enable it ?
Just like that ?

Right, perhaps we could leverage magisk with simple module for that.
But it's interesting what they have changed in dev so that it does not work by default.
My assumption is that they have changed sysfs fod naming in the new kernel (from fod_status to something else, could be checked on dev with default kernel if /sys/devices/virtual/touch/tp_dev/fod_status is still there) or have reimplemented sensor enable logic somehow. Also it would be nice to compare hal diffs (grep fod_status /vendor/lib64/hw) between old and dev miui to get more understanding.

Yeah, i'm not a huge fan of additional init script (that's why my kernel don't have a ramdisk changes) though.
So maybe we can fix it through the module itself.

Anyways, Thank you for the information, absolutely helpful.

Finger print issue on xiaomi.eu dev with this kernel are gone? I think do not respond FP on switch off display.

Can I use latest Magisk?

Many thanks dev
