Introduction
This is Zest Kernel. It's an optimized kernel for our device which includes a few nifty features. Built, on every security update, you'll have the best of the best. Features will be listed below and shared, to the most of my ability, across all my supported devices. This isn't just my kernel it's yours too - request any features you like and I'll try to add them in. However, I'm also busy with studies so please don't ask for dumb stuff.

Possibly the fastest kernel for our device, here's an AnTuTu benchmark from a fellow user on BLOD (four cores only):

Gpu can be overclocked with this kernel?

No, would you like that though? I can try include in the next release.
Personally, I find GPU Performance Profiel to be sufficient. You can enable in a Kernel Manager I advise FKM (franco kernel manager) as my kernel supports his performance profiles.

---

It looks really interesting, will test it right now.
For feature request I will ask only one thing : more battery as it's the main problem of this device , the next must come after.
Thanks for your work and be brave for your studies!

Yes, i would like that, for gaming. I prefer only the overclock, not a performance profile

---

Update released! Bug fixes and cleaned up some code.

---

Any chance to add sweep or double tap to lock screen? thx

---

Is it OC by default or just possible to OC. Would rather appreciate if on default clocks as default.

Aaand, thanks a ton for giving more hope and support for our beloved Bull.

Well there's more than one factor when gaming, CPU also counts. I was advised by @frap129 not to OC the graphics as it'll cause too many hearing issues. The OC'd CPU may improve your gaming.

I can try in the next beta update however personally I strongly dislike this feature.

The OC clocks are set if you use the performance profile within the governor. But during the normal (balanced) profile the only OC bit is maximum clock speed. This can of course be overrided via a Kernel Manager but I'd advise for it to be left.
And, your welcome ?

First of all, just want to thank you for this kernel. Seems to be running extremely well so very nice job on this. Much appreciated :good:
I have 2 questions/requests:
1. I noticed that in the little cluster ""hispeed_freq" is set to 0. I just wanted to confirm that this is correct since I've never seen this set to 0 before in any profile that I can recall.
2. If you haven't already, could you please add disable force encryption to the kernel? I didn't see this listed in the posted features. Thank you.
Thanks again for this kernel. Really liking it a lot so far

1) Yeah, it's meant to be like that. My kernel uses a Franco-style governor profile with my own changes for performance. There are many different ways to use governor profils and this style uses input as a base to up the CPU.
2) I believe forced encryption is disabled already, I can add it to the features list. For me it's more of a security flaw than a feature though, lol.

---

@LazerL0rd - One question. By "smoother LED notifier" do you mean the LED animation that jollakernel has which starts sloooowly from nothing to the right color? I'm asking because I dislike jolla's (and Shadow Kernel's) implementation. I like it as shown in this video which is how past kernels such as Phasma had it.

Yeah I never understood why you would want to not use encryption. Benchmarks even show there is no real life advantage in speed so you just lose security.

Maybe there is a real life battery drain using encryption.

I couldn't find the commit for Phasma's one but if you could provide it for me I'll have a look. I have mine based off jolla's one but I changed it a bit to be less slow.

Very small extra drain with the ARM optimizations I have in my defconfig (and so do quite a few other kernels). FBE (file-based) uses a bit more on the first unlock but then after it's fine. The battery drain isn't noticiable.

Another update today! This time it's coming with audio driver improvements, tell me what you think!
Sorry for the delay in adding requested features, I'm trying to build my kernel for a few other devices so time is short atm. They're coming soon though

Awesome. Just added IceSound this morning so perfect timing.
Thank you.
