Kowalski Kernel 1.9.1 Release

Hey guys,
it's that time of the week already :laugh:

Sorry for not posting public betas in the meantime but the work done this week has been quite hard and complicated. The way to a full 4.14 integration is getting simpler now and the results start to be really interesting. The new upstreamed and cleaned wifi driver is awesome and the schedutil governor from 4.14 really improves a lot over the older version (especially in our tickless kernel). All the other things are mostly support and tree-wide modifications. Slow and steady, right?

Version 1.9.1 release - Download here

* updated ion, binder and uapi apis to latest upstream versions
* backported schedutil governor from 4.14 with a subset of improvements tree-wide
* backported qcacld-3.0 from 4.14 msm nicobar tree and cleaned it up
​

As usual, have fun and enjoy :good:

Band Steering and FOD wakeup

Hey @pengus77,

please I have questin on wifi modul / wifi stack in your kernel. I have at home UniFi system with 5Ghz and 2.4Ghz and on all my devices (Nexus 10, Goole Chromebook, Nexus 5X,...) is working band steering good but Mi 9 SE is most of the time on 2.4 only (5Ghz signal is strong more then 2.4). Is there any "energy-saver" for better baterry live or problem is elsewhere?

crDroid 5.7 and FOD wakeup

I saw changelog from 21.8.2019 and there is: "FOD wakeup (works with built-in kernel only)". Can you do something about it?

Thanks

FOD Wakeup is not implemented in Kowalski (neither mine too in stable release) because the feature will conflict with the powersaving features that Kowalski have (where the panel is fully cutted down if dt2w is off)

@okitavera Ok it's good to know. Thanks

Kowalski Kernel b1.9.2

Quick beta just to share the latest and greatest updates from qualcomm to our beloved camera.
All works as supposed, so it's here for whoever wants to play with it until I release the next stable.

Download here

* merged tag LA.UM.7.8.r1-06900-SDM710.0 from caf (camera and sched updates)
​

As I said, this is just a small update on top of r1.9.1, so if you don't think it's worth it you can skip it and you'll get all the goodies in the next release.

Have fun

1.9.1 is working with XenonHD too

Is not in your last v7.2?

never

 

[vecino]

never

Ok I am testing your kernel now (7.2) and 5GHz holding well. Kowalski probably holds primary 2.4Ghz to save more energy. At least that's how I explain it to lay people.

that's because pengus77 using hardcoded WCNSS_qcom_cfg.ini just like krasCGQ's kernel (or maybe they're using the exact same file ? idk).

while my kernel is letting the ROMs (or vendor to be precise) uses their own configuration.
which is make it up-to the ROM itself whether they (or you too) want to support certain features or not (for example: channel bonding, tx-power, etc)

and besides, the coverage issue will have something to do with power usage.
if you have good 5 GHz and 2.4 GHz coverage in the same area, using 5 GHz is better as it will retrieve data much faster and let your phone's wifi go to deep sleep state faster vs 2.4 GHz.
but when coverage starts getting worse for the 5 GHz, and not for 2.4 GHz, you may want to switch to 2.4 GHz instead to save some juice.

FOD wakeup is workig now on http://svr4.ru/projects/grus/test/crDroidAndroid-9.0-20190826-grus-v5.7.zip with Kowalski kernel like stock kernel.

it's unofficial, anyone can put a feature in it as long as the source code is published.

 

[wyzga]

Anybody got working with PixelExperience?

 

[elpaablo]

i tested and it works fine

 

[kagazushi]

Actually seem even better than Okita on PE.

I've asked because after flashing it seems to boot, BT connects devices after while but... I can't see anything. Screen does NOT work at all.

Changelog:
- Fixed wifi driver config file loading
- Blu Schedutil fixes from upstream merged with 4.14 sched improvements
- Linux 4.9.190 merged from upstream
- Re-enabled minimal profiling for rom support (this one is a requirement from google apparently)

Kowalski Kernel 1.9.3 Release

Hey hey,
new week, new release. This one has been in the works for a loooong time actually (go look at the dev branch on my github to get an idea) but it's really starting to work as I wanted.
Brief recap of the changes between the last public beta and this one:

Version 1.9.3 release - Download here

* Implement display idle states and expose sysfs nodes to manage them
* qcacld-3.0: Add sme_power_save_api.h include
* Add toggle for disabling newly added USB devices
* sched: don't allow userspace to boost at will
* defconfig: disable misc device and rework a bit
* kernel: implement vDSO64 and vDSO32
* spi: increase timeout to make FOD more reactive
* Bump Linux version to 4.9.192

See, lots of cool things in there under the hood. First, as usual, lots of wifi love... second, FOD speed... third, compatibility with crdroid FOD... and more, lots more....

Let me know how it goes while I keep working on my lineage port. It's going to blow you away but hey, for now I keep it only for me and few selected testers. Want to give it a spin? Drop me a PM and I'll send you a link or a telegram message.

As usual, have fun !

[jay-em-ass]

Is there a way I can activate FOD with latest kernel on crDroid 5.8?
As soon as I flash version 1.9.3 FOD is not working any more.
