[FAQ] Olympus (Atrix 4G) Kernel 3.1 Project (a.k.a. Android 4.x Kernel)

[ego-T]

Yes, that happens sometimes. Not important if a reboot/battery pull fixes it.

True, I remember the first time it happened to me, it scared the sh*t out of me... Now it has appened a couple of times after a flash and i'm just "meh," xD

It looks like a "normal" thing but yes, it scared me too !

Thanks to both of you, I feel reassured now !

Epinter's CM 10.1 Impressions

Hi, first of all, as a noob that I am, I couldn't post on the main thread because I don't have privileges.

I just would like to share some observations about this room. I'm using the (2013-12-11) version with the gapps-jb-20131207.

It seems stable and smooth so far. Didn't experience any major bug. As I use it more for tethering my data plan, chat, check email and a little browsing; I think that is fair enough till now. Also I don't have anything to say about battery, cause as I use it plugged in the USB (tethering) most of the time , it is always charging.

Those of you that are experiencing problems with MTP, I could just see my ext-sd files , if I turn the debugging mode on. And if it is ON, I cannot tether. This doesn't happen in 2.3.6. Im using Mavericks.

I couldn't find the stock battery manager (if it does have one).
My search button does nothing:

This gapps package was cleaned (removed hangouts, googlenow and some other useless files). You will have to install googlenow and hangouts from PlayStore.

I could not find any Google Now on Play, I don't use it very much, just bother me that the search button doesn't do nothing
I could register (store) some fingerprints but not use them as a lock. But HERE you can use the fingerprint as a lock with third part app Data Defender.

And finally a suggestion. I tried to see the current filesystem and it seems to be ext3. Is there any way to make my internal storage ext4? Would you recommend that ? Is there any reason for not being implemented ?

That is really a awesome work, I would be glad to help in any way to improve this room!

Thanks.

Hi!
Welcome to the forums!

This kernel serves to at least 3 different roms (atrics -blur based-, cm9 and cm10.1) plus all those who derivates from these.

You were talking about cm10.1, just to clarify.

Battery manager, afaik cm10.1 doesn't have ither than stock android battery stats (settings -> battery).

Google now appeaes as google search on playstore.

Afaik, ext4 (or 3) isn't recommended for a flash based storage, due to the excessive stress out by the journal. I might be wrong, has veen a long time since I've messed with file systems. The performance of both is very close, anyway.

You can try the different kernels krystianp releases and report any bugs or regressions you find, attaching a logcat and/or a dmesg.

Yeah, that's not right. Traditionally, Blur-based ROMs have always been on ext3 while CM-based ones are (usually) on ext4. Linux on my laptop is on ext4 too even though it is on an SSD. If you look at your own phone I'm sure you'll find it is on ext3/4 as well. What other filesystem would you use anyway?
They both use journal btw.

 

[recurringintensity]

isn't that why there are features like trim?

I though so, I remember reading that somewhere on the internet. You could use ext2 or reiserfs

Thanks for your clarifications. I checked the battery stats (settings -> battery) and I thought that I would find the "battery economy" toggle button, or something like so.

I think for now I will test this kernel and make a list of bugs from now on. Where can I find the newest kernels that are released ?

So, since this kernel is ext4 capable, would you recommend to format the filesystem as ext4? I can notice right now it is ext3.

Up to you. Mine was on ext4 but I had some issues (old system, old kernel) so I switched to ext3. Other than that I don't really see any upsides or downsides of either, at least not when it comes to phones. It could depend on your usage pattern, for me there is no visible difference.

CM10.1 Epinter's Issues so far

It have been 2 weeks or so that I'm using CM10.1 epinter's room with the "stock" kernel. I mean stock is because I didn't upgraded it with the new kernels releases. I'm using the newest version of cm10.1 and its kernel from epinter's site latest version (2013-12-11).

Well so far the major issue that bothers me is the data signal drop after some time of inactivity (deep sleep). I did set up it for 30 min. So after this time I lost data connection (3G), and sometimes the radio connection as a whole, no signal at all.
When it happens I try to switch off, and on again; and doing so I can recovery the data mobile signal (3G). Sometimes I have to reboot. Ideally it should switch off on deep sleep and automatically switch on when you "activate" the phone again.

Also I noticed the tethering is kind of got worst now. It seems that the connection can't handle multiple tasks like: when I'm browsing and start doing other thing like streaming music, my ping gets a lot high. So much delay. It could be my carrier , but when I had the stock rom , it could manage multiple web navigation process.

So far it's my major complaints . But totally worth it! :good:

Now I'm thinking to flash the latest kernel available but I have some questions:
1) The latest kernel means that it's "better", in a way that a lot of bugs were solved or that can happen new others ? Cause, despite those 2 bugs I pointed out, I really like the system and it appears to me very stable. I hear a lot of people having worst issues than mines, so ...

2) How can I help the developers ? Is it enough to send the dmesg, or something else?

3) Where can I find the change logs for the kernels ??

Thanks a lot and sorry for any "noob" behavior .

First, why are you reporting issues of a kernel compiled in December? As you said, you're not using the latest version, so how do you expect to solve that issues using an old version? Install the latest from here https://www.dropbox.com/sh/npbgtozd4w0ahiv/VIA6JjSf4l and see the changes by yourself, In the latest build the users are reporting that data drop is solved but as this is an Alpha version you may have overheating issues, bad baterry life and others.

Try it by yourself and report back about your experience with the latest version.

If you want to help, Krystian left a spreed sheet to report bugs. Search for it in the Dev Thread.

First of all, this isn't meant to be used as daily driver.

1)Yes and yes, a lots of bugs has been solved, tje most important is being adressed now, tje mobile data drop. Modem drop shouldn't be an issue (afaik). Also, there might be some bugs, depending on your panel settings and other related to audio issues during calls.

2) Whenever you find some of those bugs, (mainly data drop) get a logcat of the radio (in the development thread are the instructions).

3) Afaik, nowhere, sometimes krystianp does a little explanation on what we might expect, but each release is a little adjustment based on the reports of the previous release

Yeah, I'm aware about this. But still better than running 2.3.6

I am not using the latest kernel because, as I said, I think this one still very stable despite the issues that I pointed out. So, I'm afraid to use the latest kernel and then it happens to have more bugs than the previous one.

But I will use it anyway, so I can contribute with reports.

 

[ravilov]

I disagree. I'm still on 2.3.x and I don't see any problem with it. But that's just me.

Can you spell "backup"?

 

[DuM4ll3]

I disagree. I'm still on 2.3.x and I don't see any problem with it. But that's just me.

Sure, I can understand you, there is no problem. But the "problem" that I see on 2.3.x is that I cannot use the most of my hardware, I mean, I cannot install the newest apps. The things just become so much better from 4.0 and above, like the UI and the user experience as a whole. That's why I wanna help the developers and try to learn a little bit by myself, cause like them, I do believe that Atrix still has a little of hardware power to run the newest OS. :laugh:

Can you spell "backup"?

Yeah, sure thing! I do every time before testing a new thing. And it is so easy with cwm recovery. :good:


Now, I'm curious about the fact that I can store fingerprints but I cannot use it as a lock. Could you say something about this ?

Thanks.

Well, its Moto's fault for leaving us at 2.3.6. They had the ability to move us forward, officially, but got 90% complete before giving up. Yes, unofficially they did bump us to 4.0.4, but we had to do all the kernel work with some help from Moto. Its taken us nearly a whole year since the first public release of the kernel for us to have a nearly beta (if not fully beta) stage kernel. Think of how far Moto could have gotten if they put the time and effort in (4.0.4 build was from Aug 2012, unofficially released early Oct 2012).

Android is designed to get better with each release, that is why things are so much better on 4.0 and up ROMs. The app support is being focused on those 4.0 and up android versions. GB still has a good grip on being actively used (i think its around 25%?), so there's no saying goodbye to app support for 2.3.6 just yet.

The issue with the latest and greatest is the libs as far as data goes. We pushed the limits to 4.2.2 and still function, but 4.3 is where it started to fall apart. What we need is a breakthrough on this issue to get up to 4.3 or even 4.4. I mean breakthroughs are possible, just look at the droid x. That thing was GB supported to 2.3.4, and CM developed to 2.3.7 (GB) and 4.0.4 (ICS). Then, myself and a team pushed for the creation of a 4.4. I dropped out due to a fried laptop and work related issues, but the development continued. A month ago 4.4 was released, and they're working on tweaking it for data (seems to be a common issue). So yes, breathroughs do happen. But someone needs to take charge and just build it. Fully developed kernel or not, its probably possible (droid x took defy's CM11 kernel and is tweaking it for their CM11). If there are any other issues, we won't know until we build and try it out.

Battery drain

I don't know if this will help but I found out using battery doctor with "screen off power saving" on the latest kernel fixes battery drain when screen is off, I lose abt 1% an hour... This is on cm10.1

Make a call and navigate on internet?

Hi,

I do not if it is kernel related or not.

When I make a call my data connection is disabled and I am not able to navigate on internet. Do you have the same behaviour?

 

[andresrivas]

Yup, i do recall having the exact same behavior on my old nokia 5130, though
