My bad wasn't thinking straight - I did notice NTFS / exFAT SDcards aren't able to read on r68 (or the others as well) but saw in the post that it should support it. Is it just not on the 8T? Fine work BTW I like your nice clean GitHub repo :)
Be sure to have OTG on, there's a toggle on the OOS ( I turn it on on kernel loadup, but just to be sure).
Also depends on the card reader, some refuse to work (had that situation on other devices). I have a cheap 1$ usb2 adapter I connect via OTG and works fine.
Lastly depends on the ROM support to mount filesystems and storage (vold stuff and so on). You may mount via terminal if rooted, like linux.

Thanks, I like all the things clean and simple :)

It's probably my carrier branded OOS as I can read older formats just not NTFS/ exFat. Thanks for your kernel and quick reply! I'll likely try mounting from Termux later to see if it can bypass the ROM.

Ugh... you were right vold stuff won't let me mount the card (said something like "unsupported"). Guess I'm stuck on another format card for the time being. At least my USB stick works.

Are there any frequency-voltage or frequency-energy tables that I could look at? Or a way to monitor CPU core voltage?

I've tried looking through the source to find them but I haven't had any luck

blu_spark_r74 release

New build is up :highfive:

This kernel is tested for the 8 Pro and 8T variants which I have, regular OP8 in OOS 11 is said to be working fine by some users.
You can use FKM download kernel feature, just import the links bellow in the app :highfive:
FKM download configs: oos | custom


Changelog:
  • Build with Google Clang 11.0.5 + LLD linker
  • Couple build improvements
  • CAF updates: scsi/ufs
  • f2fs: set ioprio of GC kthread to idle, Demote GC thread to idle scheduler class
  • printk: fix invalid-free on devkmsg_write(), use buffer from the stack space
  • defconfig: remove some cruft
  • Add A11 custom ROM variant
  • Latest Magisk v21.1 mandatory for root in A11 (beta atm)


Keep in mind: I will give no active support for custom ROMs (including OOS based ones).
I am mostly interested on debugging stuff in stock stable OOS (with logs and reproducible steps to replicate the issue).

Nice work bud. I have OB4 and after flashing this kernel and reboot I thought my Launcher got broken. It was just a blank screen and nothing worked. Even navbar was dead. But after another reboot it works fine. Not sure what caused that. And yeah happy to see first custom release for A11.

    Alright! Not the first time i see someone ranting against butter. Is it that bad? The only bad thing i noticed is that bluetooth was wasting too much battery. Which is a no-no to me.
    You are free to use whatever on your phone. Just don't complain after.
    If you use extras like that, you will get no support from me.
    It's in OP, people should read that before posting on a kernel thread talking about derps when using random crap that promotes ultra performance/infinite battery.
    Tired of this mumbo jumbo, users should know better.

    Works wonders on op8.
    Went "back" to A11 after some issues on A10, and even though i do like to try different kernels, i somehow always end back to this one. Ty for keeping it updated and always great / fast respons, really do appriciate you're work & time mr. @eng.stk

    Good to see you here eng.stk, your kernel is awsome, just replace my OP6T today.
    I have a feature request, can you help to to add battery idle functionality to your custom kernel? I use ACCA to limit my battery since OP6T, it will be useful if the kernel support battery idle.
    It does work with ACCA. Using it for 2 months already.

    Just a thought because I know it's no longer being developed.. By any chance did you flash that Butterlimits thing? If so, try uninstall updates to Google play services and reinstall. It's been known to cause location issues
    Removing the latest update of google play services did the trick!!! Thankx!!!

    Btw, did not use Butterlimits....

    DOWNLOAD KERNEL ZIP
    FKM download configs: oos | custom
    (No mirrors please)​


    Setup and troubleshoot: To install just flash the zip on a stock setup with either TWRP or autoflash kernel app.
    If you come from other kernel or have any issues, you should restore your stock boot.img or dirty flash your ROM before flashing blu_spark zip to avoid problems. Also uninstall or clean data of any kernel control app you're using.
    If you are upgrading between blu_spark versions, just flash the kernel zip.

    About bugs and reports: don't bother to post if a log isn't ready or without steps so the behavior can be replicated. I only active support stock OOS ROM with NO mods whatsoever (apart from root). That includes NO support if using xposed, Magisk with added modules, etc.
    If you're using custom ROMs (including stock based ones) and OOS Open Betas you're much on your own. I'm mostly interested on debugging stuff in stock and stable OOS.
    Also try not to spam the thread with OT. There's threads for all kind of stuff, use them.

    Going back to stock: This kernel installer doesn't change your filesystem. You can backup your boot.img with TWRP or kernel app before flashing blu_spark if you want to go back to full stock or just dirty flash your full ROM.
