Tested for several days the following combinations of governors

- big: interactive_pro, interactive

- LITTLE: smartmax, interactive, blu_active

With smartmax, fluidity is little worse than by default interactive - meaning eg choppy scrolling or (much easier to observe) uncomfortable text editing due to late reactions.

With blu_active fluidity is better than by default - but one must concentrate hard to observe small differences in faster touch reactions

Corresponding battery consumption results were not consistent and distinctive enough for a verdict beyond a statistical margine

Under Phone manager / Launch, Kernel Adiutor must be manually given Auto launch and Secondary launch permissions.

Still, sometimes upon (re)boot, Kernel Adiutor did not apply requested On boot changes - I had to disable and re-enable CPU / On boot option in Kernel Adiutor and reboot to enforce* the chosen governors

This also affected battery consumption tests because I became aware too late that default governors were running again instead of my intended ones.

Didn't test with the paid EX Kernel Manager to conclude if intermittent failures to apply custom governors were due to Kernel Adiutor or the kernel itself

PS: Do not lower Min Frequency for BIG (from default 807 to 470 MHz) - it will undoubtedly negatively affect fluid scrolling (initial 470 MHz is not enough for instant scrolling in eg browser, just after screen unlock or after a few seconds of idle)

[MENTION=7786725]zgfg[/MENTION] on EXKernel Manager, the bug on Kernel Aduitor is not present. You can change both clusters to what ever available and settings can be made to apply with boot.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
I

Thanks, using now EX Kernel Manager, it works - few comments:

- With Battery monitoring enabled I had annoying notification that EX drains battery, hence disabled monitoring battery (using GSAM Battery Monitor anyway)

- In Phone Manager, Launch, EX must be moved to manual with all three options (Auto and Secondary launch, Background) enabled.

Third option (Background) seems unnecessary (CPU changes must be applied on boot) but without, when I didn't unlock the phone (PIN) quickly upon booting, EX failed to apply changes

PS: Now using blu_active for both big and LITTLE.

Fluudity is ok although I'm not sure how it reflects the battery (better or worse - anyhow, but minimally)

Reason: I was monitoring in live how CPU frequencies scale up/down and it seems that blue_active scales down faster than default interactive (also faster than interactive_pro) when load scales down.

When load scales up, all three scale up practically immediate

[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Are you flashing with TWRP for Oreo from HWOTA7 thread, and by selecting to flash to the Kernel.

Also, although you are on RR, you must know what was your stock Oreo build number, eg b535 or b539, and to flash the corresponding ECO kernel and/or the corresponding stock kernel

It works as it doesnt changed anything. B539+B540 using same security patch.

Stock got compiled with latest working upstream 4.4.166 and should be up soon as UBER is done. More should come after fixing issues on higher sources.
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
b540 has Security Patch Dec 5, b539 was released by the end of Nov and (must have) had November Security patch (maybe sec patches don't differ much)

Do ECO Kernels b535 (or newer b539/b540 builds) work with b535 Patch02?

Also, b539 ECO Kernels work with b540 upon its OTA patch (before OTA patches all worked fine, but asking now if Huawei enforces Android Verified Boot and if it checks the authenticity of Kernel)?

Edit:

- Tested (old, from Nov) 4.4.162_11.18.18_lin_B535 and it works fine with b535 Patch02

- Tested 4.4.171_01.19.19_lin_B539-B540, got a bootloop with b535 Patch02

- Compared MD5 hashes of stock kernels from b535 and b535 Patch 02, they differ (interestingly, hashes of stock ramdisk for b535 and b535 Patch02 coincide)
[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] dkionline:
1st, its same huawei practice to patch all devices again. It needs simply a dm-verity patched ramdisk, no kernel issues on that side. If there was any, i would know it before any other.

2nd, avoid patches and use new builds instead of useless updates.

Month ago I had manually installed b540, happily using newest ECO kernels available at the time:

https://xdaforums.com/showpost.php?p=78541407&postcount=75

But later I had to reinstall AL10c00 and then sticked with what was latest officially pushed by OTA: b535 with Patch02:

https://xdaforums.com/p9/developmen...ta7-p9-eva-t3820849/post78721851#post78721851

However, yesterday evening received OTA updates for b540 and its Patch02:

https://xdaforums.com/showpost.php?p=78763850&postcount=1405

Hence now back on official b540 and using your latest ECO kernel v4.4.171_01.19.19_lin_B539-B540, all fine

PS: OTA patches 02 are now official/pushed by Huawei, enforcing DM Verity, hence one must patch Magisk with both Preserved Encryption and Preserved AVB - and everything works fine :)

EDIT: THIS THING IS SICK! I just tried a race in Asphalt 8 and...My framerate went up by a lot. I don't know how much, but certainly it doesn't feel like 20 FPS anymore, even on High in the middle of Tokyo.

This kernel is so awesome, thanks for your work. I just hope I don't get SoD or anything like that. Custom kernels tend to fail sometimes for some reason.

I see that this kernel has EAS by looking at the kernel/sched/energy. c and kernel/sched/fair. c Nice!

[Huawei P9 ROMs, Kernels, Recoveries, & Other Devel] zgfg:
Probably will work - P9 and P9 Plus shared the same stock Kernel for b535.

Btw, once I flashed a custom Kernel for Honor 8 to P9, and it worked.

Have ready your P9 Plus b537 stock Kernel, to flash from TWRP in case of problems.

See the answer on AndroidHillfe how to extract stock Kernel.img by Huawei Update Extractor from update.zip, and/or to dump it by dd from Terminal Emulator or ADB shell.
