Wow, bring it on!

What i would be interested in is whether battery consumption is therefor increased or if it remains the same? Either way, i hope this gets the attention it deserves. It doubles the fps, this is crazy!

nvidia is not involved in this project according to linaro website

the dev in the video mentioned they were only developing for ARM processors.. .. looks like the wait begins

99,99% of all Android devices are ARM. Intel has just ported it to x86 but there has never been a worlwide release of an Intel-Android phone yet, so it makes a lot of sense to keep it on ARM. Needless to say that the HOX is ARM-based too. No need for sad faces...

basically if u use custom rom which is based on AOSP, AOKP & CM9 your in luck because these developers can use this now,
while sense have to wait for htc to update... thus us <---- right?
personally i dont see if happening anytime soon

Not happening on tegra just because Nvidia is a bad company and will not release any source for their drivers and so therefore there's no way to port the timizations over.

Wouldn't google have to implement this into their source or can this be done via kernel update from htc ?.

I would guess less battery usage. It goes faster because the code is better optimised and therefore fewer instructions to achieve the same goal.

I don't think the ABI is affected by these changes, so it should be possible to build the kernel and still use the prebuilt nVidia binary drivers.

as you can see in the users feedback opf this ROM lots of GPU acceleration issues
on the linaro website FAQ
its actually said they dont support Nvidia processors since NV didnt join the program
anyway ill keep my eyes on that ROM

To be fair I think nvidia will keep a close eye on this and work that has worth they will use internally, so its not all bad. It does however mean a long wait until users see anything from it though

Most likely nvidia would like to release the source but can't because of non disclosure agreements with 3rd parties. Anyway acoording to the video most optimization is to the cpu so even on sense we could soon see some of the optimizations on custom roms.
Also a while ago I build custum RPM packages on Mandriva, when building on Mandriva by default it uses strict aliasing and many packages refused to build but adapting the code to compile was relatively easy, even for someone like me with little to no experience in coding.

This would do really, really great on the one x.
How hard is it to port the toolchain to tegra3?

Linaro+Overclocking+JB=???

I can bet that the ppl who created Linaro will find errors in JellyBean.
What do u think this would mean if you were to Over clock the Nexus, have a JellyBean, and have a version of it in the form of Linaro???
Would it be like having a crazy fast phone on steroids???

I get the impression that you aren't familiar with what Linaro really is. It isn't about finding errors in Android. It is about (in this case) modifying Android to take advantage of newer GCC compiler flags. It was never about finding errors in Android.

2) No. I tried Linaro and over clocking on ICS. The results were very minute. In fact, the only thing I noticed is that the recent apps button launched faster. That was it.

From what I have read the entire rom/kernel needs to be compiled form the Linaro TC in order to see the true benefits. Most roms just have bits and pieces baked into them.

Yeah me too. But when I clocked up to 1.4GHz on Franco and Ran Linaro, it was faster then a non linaro Rom on 1.2GHz.
Since JellyBean exceeds this, imagine how much faster it'll be.

Well, GNU/Linux is an open source project that is constantly evolving. Due to its OSS nature, there are constant changes from multiple sources. These changes bring things such as new features and in this case, improved performance. Some of these performance improvement have been made to compilers. However to take advantage of these compilers, flags have to be set in the source. Think of a flag as an optimization. However, if the code isn't coded to work with these optimizations, additional changes must be made. Thats what Linaro has done. They modified Android to accept compiler flags for gcc 4.7.x. Android is designed to be compiled with gcc 4.4.x.
There are some caveats to this. If not all of the code is ready for the optimizations, things can break. Some flags can destabilize an application.
Think of Linaro's optimizqations as bleeding edge. If you play with bleeding edge, you will bleed somewhere. Things will break at some point. This is the nature of the beast.
As a point of reference, most Linux distros are not bleeding edge for this very reason. Ubuntu uses old stuff by the time a new release rolls out.
Linaro handles several projects. In fact, Ubuntu uses Linaro GCC in their repos.

Thank You!!!

Lineage for this device?

As the title states. Now that we have root and an unlocked bootloader do you think lineage is will make its way to this device?

Not a fan of lineage code.
We need a aosp rom like Purefusion.

We need Kernel source from Motorola first. They are dragging their feet like always. Without kernel source, we can't get a 100% working TWRP for custom roms to flash

Agreed. We need them to drop source code like they said they would.

Looks like I may be getting this phone instead of the Note 8. Come on Motorola......release that source code.

Kernel source was given by Motorola. There is my git with the edits for a regular machine running GCC 4.9 to build a kernel that boots and works.

How much less is less?
If you build it they will come.... ("Field of Dreams" movie line) Seriously, though, I do wonder if giving up stability and features is worth it for minimal gains in performance/benchmarks? Motorola's take on Android is already bare-bones compared to Samsung! With Lineage, it's slightly easier to theme, true, but Substratum suffices for many individuals on stock. I haven't tried Substratum yet, because I don't like dark themes. Don't get me wrong, I want Lineage to succeed! The more open-source options the better! But, is it worth it for the principle, or modest increase in speed (maybe)? Bugless and not losing any features, I would run Lineage; so, we'll see, because it will come in due time.

Totally correct. Our device is so close to stock it's ridiculous. We pretty much have a pixel phone with slower updates and mods. Which I'll take over the boringness of a pixel. Yes substratum would be pretty cool but I know things are coming we have a kernel being updated to the latest kernel version available. We're testing twrp right now and have it 95% working and now we have twrp and magisk and an updated kernel all going at once things are coming along slowly but I feel they will pick up soon

Yes, they were released. Kernel builds fine. For AOSP stuff we need vendor files. We are piecing things together. All builds have failed so we haven't even had a chance to see if it boots.
Why hasn't a kernel been fully released? (Besides the upstreamed one in the custom ROM section) because of encryption not working right in TWRP, you'd lose root when flashing as TWRP can't put the ramdisk back correctly hence no root.

Somebody should start Lineage. I would do it if I had enough experience but I don't yet. Huge tasks like LTE not working, etc., can arise depending upon the particular phone....
The attached screenshot illustrates the dynamics quite well. I was initially mildly surprised by the Lineage developer's response to someone, "When you start paying me." But, for some developers who devote lots of their time to Lineage, I suppose the questions can become tiresome. Every developer is different, of course, and it is a global scale endeavor.

any thoughts on android go?

Just heard about Android GO. Is there any thought to building it for Galaxy Nexus? With the frustrations of no root for my g6 I've been playing around with my old Nexus device. I've never built a room before but am more then willing to learn or help.

I also would think this may be a really good thing for our devices, seeing that there has now been Unofficial LineageOS 15.1 builds already being made for First Gen Android One Devices. I would also be willing to learn and test out developments, however I would probably still leave it to the professionals like @Android-Andi, @Ziyan, @nailyk, @osm0sis and @amaces.
I am positive that with a combined effort we all could make our "retro" android device, bang up to date with Oreo Go, which may also help improve speed due to memory improvements that have been made in Oreo Go. I also wouldn't be surprised if one of the mentioned above isn't already in the process of doing this.

I have not time at all (for that device) and am not good enough at kernel tasks.
If someone is able to port HWBinder on our 3.0 kernel I guess being able to help on a few things. If I get some time one day, I will try to backport it from 'my' Sony 3.4 one.

Binder and other backports are not the deal breaker for Oreo on K3.0 (see our UA staging trees). The problem is lack of usable (and public) DDK UM blobs, which is much harder, if not impossible to fix. Also, the availability of Go GApps is more important than building a Go ROM.

Gapps are not important for me
I though the graphic driver was open source ?
Sorry for noob question, but I do not know the omap world...

I dunno if this would help any of our wonderful developers, however I just seen this "Oreo Low-RAM Property Mod" basically giving Oreo an Android GO style update. If I could build it all myself then I would, however I don't actually know where to even start.

Great job! Seems good so far

Added a kernel space blocker to don't allow execution of magisk root optimizers such as LawRun
What does that mean you can't root with magisk? That's ironic because yesterday I was talking to someone who said the makers of hentai OS don't like root or twrp.
To that I say you guys do understand most of us would rather be rooted stock than on some nonstock rom without root?
It's actually sad when open source coders make a rom and want to say you can't root because it messes it up and we can't fix it so no root. That is what we do at XDA.

Those are not "optimizers" they are doing worse for your device. Then you are the one that complains "x kernel its bad" just because you used one of those "optimizers" that made it bad. However no one forces you to flash anything .

I don't need to flash custom kernels it's built with stock source code, so it's stock kernel with a gesture or something added but generally speaking they don't perform better or have better battery life. They certainly don't do both battery and performance better than the guys that wrote the stock kernel source could do.
You guys get carried away on Xda. We appreciate anything to contribute but most developers don't do it for free they make money with donations I've seen them get thousands of dollars. That is their hope to it's only I do it for me and no one else when things don't work right.

If someone can produce a kernel that can beat a benchmark score of 713000 on AnTuTu I will be more than happy to try it.

If you think antutu benchmark matters or any other score in any benchmark it means you don't really know much. The only benchmark to ever matter is UIBENCH jitter test. Where's stock kernel its garbage at as well as any other stock kernel by any manufacture not just xiaomi. The smoothness its not even comparable. Benchmark scores do not matter at all your phone can perform much better including gaming while having a lower score in benchmarks.

I understand that Benchmarks aren't everything but it does give us a guide to go by. For example I have a S10 lite ultra and it has SD 855 gets about 489k and the Poco f3 got 713k and it does work a slight bit faster side by side opening apps and doing stuff. It's only on XDA that you hear people talking about it means nothing.
Let's not get carried away if people on Xda could build a better kernel than xiaomi or Samsung or whoever they would have to know how to write code and they don't. Xiaomi isn't waiting for their kernel source it's the other way around. You can't use Xiaomis kernel source code and than claim you have made it better performance and battery. Because I've been flashing roms and kernels now on like 20 different devices for 4 years and it never makes a big difference. The best thing a developer can do is make permissive for Samsung kernel. That truly adds something that isn't there already.
No the truth is if there are ways to say something is better or not on Android phones that doesn't show favorable results to whatever someone has built than it's looked at like crap because we don't like the results. You guys try to speak down to people like you don't know crap about anything if you think that matters. Really, I see Amd, Samsung, Google, Intel, pretty much everyone using benchmarks to show their products being 30 percent better. They probably don't know real development.
I'll tell you what what does that jitter test for and you give me your best custom kernel to show it? I'm on EU rom.
It's like best rom? Everyone is different and it depends. No everyone wants the same thing.
Stability, performance, battery there's really nothing different. The only thing that is different is if someone wants pixel rom to mimic pixel devices or OnePlus rom or Samsung one ui rom. Don't get me wrong I enjoy tweaking my devices but is anyone with A/B slots and super partition able to restore device with twrp?

Just today I seen casnova post a screenshot of Geekbench which is weird because he probably didn't realize it doesn't matter Benchmarks. But his was 900s single core and 3300 multiple core so I quickly ran Geekbench to and I scored almost the exact same thing.
Here's why I say this stuff because the so call developers on XDA have took all the fun out of it. Your not developers you take other people's work and slap your name on it while changing as little as 1 thing or sometimes nothing. Your compliers or something like that not developers. You guys belittle noobs because xda allows people that complie code to talk down to newbies who want to ask questions but the truth is that actually makes them look bad because they don't know the answer most of the time. ETAs aren't allowed because developers don't actually know if they can fix anything or if they can build again.
All of the rules are stupid and make no sense unless you make it so people have to act like developers aka compliers are someone special. Who's so smart and just does things to be nice and the donation link.
It's to the point where I just want to see all the new members stop kissing ass and tell the developers your not a developer unless you have a degree or work for a software company but if you did you wouldn't be on Xda.

The xda developers have gone to far, you guys have gotten big heads puffed up chest and think your hot stuff. It's ruined xda completely and it's not a helpful website anymore it's thousands of threads of it's already been answered search the post, nice rom dev even before they flash it. Now if you ask about a feature the doesn't work they just blow you off. That means threads are pointless for information on the software.

Guys, would it work on ArrowOS 12? Can it be flashed via sideload?

I'll tell you what what does that jitter test for and you give me your best custom kernel to show it? I'm on EU rom.
It's like best rom? Everyone is different and it depends. No everyone wants the same thing.
Stability, performance, battery there's really nothing different. The only thing that is different is if someone wants pixel rom to mimic pixel devices or OnePlus rom or Samsung one ui rom. Don't get me wrong I enjoy tweaking my devices but is anyone with A/B slots and super partition able to restore device with twrp?

First of all you have literally no clue on how a kernel works and what those modules do. There is no such thing as "building a better kernel than xiaomi, samsung, etc", no one would be ever able to make a kernel from scratch. The kernel itself firstly comes from Linux where's for our case on snapdragon Qualcomm modifies it and releases sources for each SOC then it goes to the specific manufacture that wants to create their phone and has to add the necessary code in order for their phone to work with the components they chose and usually they try to "tweak" the kernel which is literally doing worse 90% of the time. Qualcomm has a lot of stupid implementations baked into the kernel such as pl, hispeed, WALT, which are the reason the jitter its horrible with stock kernel, instead following mainline which is the best thing to be done. Benchmarks are useless because they are made to run on based on what usually the phones ship with, they are not designed to measure properly the performance of a phone therefore i have a lower score with my kernel but surprisngly jitter its 10 times better on "my' kernel, as well as normal usage and gaming too. I don't care what other devs posted about benchmakrs, i dont think my name is "casnova" or whatever, i dont talk for them i'm letting you know how it work. Also regarding "Your not developers you take other people's work and slap your name on it while changing as little as 1 thing or sometimes nothing", why dont you check github? why do you even talk without knowing what its really happening? its funny how people complain about dumb stuff, as i explained you that blocker its meant for people like you to not use x,y,z modules then to complain that the kernel is bad just because you used some random "tweaking" module and it underperforms. I don't think anyone forces you to donate, as well as barely there are any people donating, also i dont see where i ever asked on my kernel donations or anything, he's free to have a donation link in case everyone likes his work. Regarding using other's work, ever wondered why there is a thing called open source?, why wouldn't i use someone's great work in order to improve the kernel? i should do everything myself because you say so LOL. Please stop being delusional, before you ever write something on xda or anywhere else think twice. Im not here to beef with anyone i was explaining you why they block those "optimisers" that you are talking about, however you started talking about a lot of totally different things than what i said. Also if its that easy why don't you do it yourself and make your own kernel, by your analogy those "optimisers" would be bad too because how they can make a better job than qualcomm, samsung,oneplus blablabla LOL? You dont even know what they actually do. You share a lot of missinformation and you should stop. Have a nice day, i don't even know why i'm even arguing with someone like you, i wont reply to any of your answers after this.

First off I have made a couple of custom roms , twrp, and no I haven't made a kernel because it doesn't matter. For instances overclocking used to be a huge deal and now you don't see that ever. It's because it never did anything you could over clock it and if you watch your CPU in a kernel app like kernel auditor or Ex manager it would run at the stock frequencies much like the CPU does now if you try to lower clock speed or max it out. I'm aware that a kernel makes the hardware on the device work mainly the CPU and GPU and every OEM has to add their source to fit it. Here's how I know it's bull crap, now developers are saying kernel is enforcing and made with this tool chain as if the kernel isn't built with enforcing from the get go on stock like that's some feature they added. Me personally not worried about security I still prefer Permissive and yes I know it weakens security but in 5 years of doing this I have never heard of anyone hacking an Android phone. Even with the source code provided it's still difficult to make changes so I don't think people who could do it are going to waste their time. The monthly security patch is not a big deal it's funny that everyone thinks that is great when next month they will tell you last months security patch has security flaws like every month before it. So basically no patch has ever been secure.
If real features were added like double tap to sleep gesture
Color display RGB control
Sound modification so you can add gain on speakers, ear piece or headphones
Those days are gone because no one knows how to do it anymore on new software. Also most kernels say better performance and battery but neither the performance is any better nor does the battery last longer so I don't see how those claims are made. Wait I know because on Xda you can claim anything and everyone just says buttery smooth and long battery life thanks Dev. Before they even flash it.

I built 3 roms for 3 of my devices and I didn't start calling myself a developer because I had to get the vendor blob, kernel source, and lineage files from someone. I really think everyone just builds something or makes a flash able zip with a shell or script in it and immediately starts calling themselves a developer. I have owned the Poco f3 for a couple of weeks now and the TWRP thread is a waste of time. In the opening post it says backup and restore because they just copied and pasted the Normal twrp page. But than you search and almost nothing is being said about restore and you ask and no one will answer you and it's because it doesn't work and no one wants the devs feelings to be hurt. Well that's lovely but the point of a help thread is to discuss problems and solutions but it's became pointless the only thing threads are for is to say thanks for the software and to tell everyone that they don't spoon feed noobs to look it up and thats just stupid again that is why the Google search takes you to xda and that thread because you looked it up. Twrp would be able to backup and restore if xiaomi or Samsung made it because they would know how to make it backup slot a or active slot and restore it to inactive slot or whatever slot it needs to be because that's real development. I'm not trying to be a **** but it's gotten stupid I don't even bother looking through threads anymore because it's a serious waste of time because no one can say anything that might upset the person who made it. Well than don't make it I don't really care

a good kernel, I use it for Xiaomi.eu stable

Can i use this kernel for gaming ?

When I install stock miui, next LOS and my apps , every time I have different results with kernels. I do not understand how it is possible to have always different results for the same software for next tries.
It is third installation of all in my poco f3 and after testing some kernels, this one is a winner and consumes only 0.15% battery every hour during the night. Thank you for the kernel v2.
Edit.
The installation of this kernel reinstalled default LOS recovery. When I installed TWRP and again rooted the result was killed. I see 0.56% during night and this is worse result than own LOS kernel has. I lost a time for this kernel I afraid.
