After updating to 1.5.0, Spectrum shows me that it's not supported with this kernel. You probably did something wrong again, but Spectrum is not working.

I reinstalled Magisk and everything seems to be working just fine.

Patching the ramdisk in combination with magisk seems like being playing lotto on this device. Sorry but i don't see any way atm to make this more reliable. Same story with the customs ROMs atm. Only recommendation atm. Flash until it boots.

governors

Where to find info about this governors ? and whats the difference between shedutil vs helix_shedutil vs smurfutil ? which is the best for battery saving in theory :)
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
Several posts up you find a short description. In theory smurfutil should be most battery friendly as it combines the load based frequency ramping and the limited frequencies in suspend mode. Explained in the OP too.

What are you talking about? :confused:
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
I've not found a kernel having helix_schedutil that is based on 4.9.x sources. Only 4.4.x. The 4.4.x implementation is not working with a 4.9 kernel. You've to make some changes. But the heart of helix_schedutilt, get_next_freq, is helix_schedutil like for sure. You're Team Helix member, right? And because of that my thought was that you maybe could review the code. I'm mostly sure that i've transfered everything that makes it helix_schedutil, but well it's always good to have other people having a look at it.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] ZeroInfinity:
I was the one who created it (as with all the governors created for Helix Kernel), with some ideas given by [MENTION=5736502]Kyuubi10[/MENTION] and [MENTION=5060769]Mostafa Wael[/MENTION] . Unfortunately, all my previous schedutil based governors are deprecated, but you are free to do whatever you like with them. As for porting them to 4.9 sources, the function with get_next_freq is enough, that's pretty much the only part we've changed (as well as the code for adding more tunables near the bottom section of the source file.).
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
Thanks [MENTION=4388232]ZeroInfinity[/MENTION] and your Team for coming back to me and for your permission to use your governors as 4.9 ported versions. That's the reason why working on Android topics makes that much fun!!!

Sorry for not keeping the original commits, i'm still learning how to use git like a pro.

Tunables and get_next_freq are present and well all governors are working without issues.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:

[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] szakes1:
So, you say that Spectrum might not work randomly and it would show me that the kernel is not supported, right? You suggest me to flash the SmurfKernel until Spectrum works?
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
Yes, that seems to happen sometimes with the custom ROMs. No idea why, i'm using the same method to inject files into the ramdisk Franco is using. For Spectrum modifying the ramdisk is the only working method. If you want to use Havoc you have SmurfKernel included now, no need to flash it.

Gesendet von meinem ONEPLUS A6003 mit Tapatalk
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] szakes1:
I found out something. The SmurfKernel included in Havoc OS doesn't work with Spectrum, only after flashing the SmurfKernel.1.5.0.lineage.zip (I didn't test the other versions), Spectrum seems to work. I have no idea why it happens. That's why I flash SmurfKernel over already included SmurfKernel.

Your included kernel in Havoc OS just doesn't work with Spectrum. I did 2 clean flashes to test it out. Only after flashing the kernel manually, Spectrum start working.

I have no clue whether it is your kernel's issue or the ROM's.

By the way, is there any way, where I can customize the kernel to drain a little amount of battery while idling? The problem is; when I leave my phone on a desk for a whole night, the battery drains about 13%. Is there any way to avoid that? I remember your Xiaomi Mi Mix ROM, the Resurrection Remix ROM and the kernel there didn't drain even a single percent during night.
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] marko94:
for me idle drain during night is max 5-6 %
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
The kernel is not draining 13% over night. An app or service is draing 13% over night. I would use the known tools to investigate what is keeping your phone awake and drains your battery.

Checked my phone, 86% deepsleep, 4% awake, 10% screen on. Betterbatterystats is a good one, or Wakelockdetector. You definitly have something on your phone going mad. The kernel is just doing what the system wants. It is never the reason for excessive battery drain.

what do you mean by CRC control? (cyclic redundancy checks?) if so how do we disable it (for better performance)?

also can you please give the option to disable FSYNC completely?

currently flashing every kernel, so far smurfkernel has got my attention, smoothest experience so far so i will use it as my daily driver.

thank you for your work, where can we donate? :D
[OnePlus 6 ROMs, Kernels, Recoveries, & Other Devel] pappschlumpf:
Yes, crc off is faster. Your description is correct ;)

For a fsync disable switch we have no need with using dynamic fsync. If screen is on fsync is off and if device goes to sleep fsync is on. The kernel has non blocking fsync too which means that even an fsync on wouldn't be a remarkable performance hit.

I also notice a bunch of wake locks being blocked by default in ex elemental kernel manager

can you leave these enabled and give users the option to disabled them please, I just don't see other devs blocking wakelocks by default

Hi.

I'm new in the OP6 and also with that kernel. But I heard papaschlumpf did a pretty good job with it, so I wanna try.

I've read the thread, but still I'm lost when it comes to the download of the right zip file.

Those 4 different named files, which is the right one to choose for the havoc rom I'm about to flash.

I'm missing a bit more information in the OP to make more clear what flex and not flex mean.

I assume the files with custom in the name are for lineage based ROMS, like havoc, right?

Would be great if one can help me out here.

Thx
