Hi! Can you add CPU overclocking to 1700 Mhz pls ?
This is the normal frequency for Snapdragon 616.
And... It would be cool if you change CPU frequencies to nice numbers (200, 400, 600, 800, 1000, 1200, 1400, 1600, 1700)

And yet... Can you add GPU overclocking (if it's safe), I saw GPU overclocking to 700 Mhz in ZPX Kernel.
Thanks for the best kernel :)

that OC in GPU doesnt give xtra performance but overheat my phone. kudkernel give better performance in gaming based on my experience...

I'm agree: GPU OC is not good idea.
But CPU OC may be very useful for single-core games and applications without overheat (because this CPU support this frequency by default).

I won't add CPU nor GPU overclocking support, but I may add GPU underclocking support if possible.

Xiaomi should have a better reason on choosing to lock our performance cluster's speed to only 1.5 GHz (or more accurate: 1497 MHz, 1497600 Hz).

I don't want to expect more on this phone other than a phone that's suitable for my everyday use with moderate gaming.

Modifying values of these are practically impossible.

PS: The only combo of that 'nice number' can only I see on Exynos 5410 chipset.

i think its not a bad idea to offer OC on the CPU. u can set the default cpu clock at 1.5 n let the user decide wether they want to increase cpu clock or no :D just a suggestion :good:

Finally, I'm coming back for real into Redmi 3 kernel development!
I was busy and it takes me full two weeks to work into kernel, especially after rebasing it over new LineageOS kernel. Some features you wanted to see might not here, but some of them may return in the next version. Sorry if you feel like I'm disappointing you.

Brief changes:
  • Kernel that you might know as KudKernel, is now Chtolly Kernel. Old KudKernel builds however, are still archived for those who need them.
  • Rebased and updated CAF base to LA.BR.1.2.9_rb1.18.
  • Updated Linux kernel base to 3.10.106.
  • Updated WLAN (prima) driver to lnx.1.0.c4-00036.
  • Compiled using GNU GCC 7.1.1 toolchain.
  • Properly optimized for Cortex A53 CPUs.
  • Removed core_ctl.

For full features of the new kernel, take a look at the revamped OP.
Enjoy!

Okay, enough discussion about my anti-piracy check. I've decided to keep my anti-piracy check inside my init script, but I'll improve it a bit to include as many apps as possible.

I'm detect high cpu load (one core at 90-100%, other cores at 0-2%) on crDroid ROM (unofficial, last version).
Kernel version: chtolly-r7-ido-20170617
Can you check this issue on other ROMs ?

I'm currently testing my changes on my device, but as far as I see, it's not happening on mine. I'll double-check it once I'm back to the release kernel.

    • Swipe flash button.
    • Enjoy KudProject release!

    [SIZE=+1]Uninstallation[/SIZE]​
    Just flash stock boot.img from your ROM, or just dirty flash your ROM. Re-apply systemless mods that you've.

    [SIZE=+1]The end of Chtolly/KudKernel era[/SIZE]​

    16 stable releases, 6 under KudKernel and 10 under Chtolly Kernel. 6 months of Nougat kernel journey, actually doesn't enough but sad to say I've to mark release 16 as the End of Life of my Nougat custom kernel lineup under these names. This last release only includes Blueborne vulnerability fix at kernel side, nothing major, nothing minor.

    However, last release doesn't mean that I'll be leaving development, I've something behind to work with, two devices, which isn't an easy task. I'm currently rebasing current ido kernel and working on mido kernel bringup. I've to balance them both, but I need to keep my principal of avoiding unnecessary things. My next kernel lineup will be probably 75% for Oreo.

    See you soon!
    Albert (Kras).

    [SIZE=+1]Known Issues[/SIZE]​
    • HDR in some camera apps might not work.
    • For some reason, pstore files are generated even when there's no kernel panic on previous boot.
    • A random reboot might be expected during usage, but it's fine because nothing I can really do on this since LineageOS stock kernel has the same problem.

    [SIZE=+1]To-Do Lists[/SIZE]​
    • None yet.

    [SIZE=+1]Removed Features[/SIZE]​
    • System V IPC support
    • CPU boost
    • dev/mem support
    • conservative, userspace, and powersave CPU governors
    • All TCP congestions except westwood, cubic, and reno
    • Parts of debug and tracing stuffs
    • Everything else marked as disabled in this commit

    Hi,
    Kernel release 14 is now available to download.
    This version onwards will now include doubletap2wake support for FocalTech panels (thanks to flar2 for wake gestures driver, and ariafan for porting it to Redmi 3). Kernel is now compiled with GCC version 7.2.1. Enjoy!

    Regards,
    Kras.
