Re: [9001][KERNEL] SkyHigh V1.4d [Updated 06-04-12] [More fixes for SD Card issue]

@skywalker01 On a bit of a side note, i want to thank you for all of the long and informative posts you've written on xda. For me and many other users they are hugely clarifying and contained a lot of information and insights.

Since you dont have the time to full-on develop, might it not be an idea for you to write tutorials or other kind of explanatory threads? I've always seen your posts as really good to read small tutorials/explanations on how stuff works. Also, you're using a very attractive style of writing, which makes it easy to read for non-advanced users, but still informative for the more advanced.

Looking at the amount of thanks those 'explaining' posts of you have always been able to get, and the amount of knowledge you have and subjects you could write about, i think there will be many people interested in reading them!

1.5 kernel and you will become a legend

Man, I use your kernel from last year (1.4d), both on GingerRevenge and stock GB Rom). You did a hell of a job and I still belive that is room for more. There are not a lot of GB users? You're wrong! I have a few friends with S+ and all of them use your 1.4d kernel version. Why? Because they still use GB Stock Rom. They don't want ICS or JB custom made roms, they just want stability for their phones. Not everybody is nutts about JB or ICS, they want a fast and battery friendly phone. And your kernel help this wishes!

If you have a 1.5 version of your kernel, just give it to a few people from this forum for testing (I think that you will find a lot) and after a few weeks, when they can say that you have a bug-free kernel, you can relese your ULTIMATE kernel relese. Give the crowd what they want and you will become a legend(If you're not already a legend)!

PS: If you not want to work on this kernel,

maybe you will find someone to continue your work

! An apprentice or maybe more! Your choise!
[Galaxy S Plus I9001 Android Development] lontu:
Lets all I9001 Gingerbread users (also ICS/JB users have love for GB) please start appealing Skywalker for an update of the kernel here... :)

We may goto ICS/JB but always returns to GB for stability, battery life and performance..

AW: [9001][KERNEL] SkyHigh V1.4d [Updated 06-04-12] [More fixes for SD Card issue]

Hey skywalker!

I really really appreciate your work!

I am still using Gingerbread (mostly my own ROM or GingerRevenge which is a very good ROM )

So i would be very grateful if you would do the i9001 users a last favour. I can really understand your points and it must be depressing.

Although you are the best developer i've ever seen on this forum and it would be the greatest news of 2013 if you could release your 1.5 version.

Due to the support problem:

What if you would ask a moderator to close this thread and explaining your personal interrests in 1st post?

But nevertheless, I will always use Gingerbread cause ICS and JB is simply not fast enough! In no dimension they could be faster than GB on this phone!
[Galaxy S Plus I9001 Android Development] broodplank1337:
Ok, first of all thank you very much for your extended reply, I always learn a lot from your long and well explained replies. In my eyes you're a true developer!

GB isn't bad at all, atleast in gb everything works the way it should (fm radio and gps working fine), but the samsung layer on top of it kinda screws it up I think, also the reason why the didn't release ics for i9001, the TW framework would take to much memory... look at aosp, CLEAN and fast, my AOSP runs faster then GB stock roms from samsung, but I haven't planned planned any successful route in navigation since i switched to ICS, which kinda bothers me. although using a custom gb rom and your kernel makes things a lot better ;)

And I've studied the layer architecture once, but it was to long ago to remember. I did remember that dalvik actually is VM that runs on top of your android installation, and it converts it input to smali for faster processing (don't know if it actually does get faster by doing this), I think if they build the java interpreter natively it would boost the performance in general. (correct me if im wrong)

I didn't know that the intermediate layer was all about the device specific things, I assumed it had some preparation files for building the component, which is true, but didn't know the device specific values were hidden in there. Learned something new :).

I know the libs are highly hardware dependent, that's also the reason I used the CM9 libs in the first place, because they are the closest you can get to the AOSP libs, also I think it's a pity that samsung only released like 0.5% of their sources, if they included all libs building aosp would have been way easier.

And idd the device specific stuff is mostly in /external and /hardware, that's why I figured to use those folders from cm in the aosp environment, and it does improve the compilation process by loads, but still doesn't generate any working stuff. On the bright side, the Galaxy W (i8150), which is almost identically to the i9001 is getting official CM support, so that means this can become handy for me as well.

Thanks for the explanation about the layers, I didn't know there was a max of 1 level regarding communication.

And idd it's theoretically impossible to compile it in a working state for the i9001.

Also I don't know what CM exactly did to get it working, I think they first collected a lot of hardware and external libs then rewrote the framework (I really don't know to be honest). Could you give me a push in the right direction?. I thought about some ways, but I don't know what is the most effective, for example I spend the whole weekend on some small part that actually isn't going to make a big difference after all, wouldn't like that to happen.

Thanks in advance, and thank you for all your help skywalker01, you're great! :D

AW: [9001][KERNEL] SkyHigh V1.4d [Updated 06-04-12] [More fixes for SD Card issue]

Holy moly. Thats a true story there skywalker!

Lets see if i can get you to release v1.5.

Look. Just as you told, before soneone can develop things like a Kernel or Rom he.must learn how to do it, right? How everything is connected together, how it works and he must know what every single line of code means, thats the only way to "translate" it to another "language", right?

This takes years of learning and a lot of practice.

What i can say about that: I will never ever be able to translate it. Not even the first sentence. Its just too much for me. Its a rediculously long book to learn and i have no time for that.

And this is where Developers like you get in the game.

You already know how to translate. You can and you did it. So why not releasing it? Imagine someone finds out how to translate the language of mayas, he woukd translate it for himself and tell people he has translated it, but he wouldnt release the translation?

You know? There are alot of GB users, even if they arent here ( maybe its because everything went to cm9/10 over here. Maybe yiu can change the way it is over here. Its your decision. I think you should release it. But its in your hands.

So, im using the kernel as Beta tester now for 2 Days. Its stable and fast. Battery drain is almost like Stock kernel, but i think thats the OC feature.

I didnt found any bug. Everything works as it should.
[Galaxy S Plus I9001 Android Development] hiej:

beta test in progress

so i have succeeded insetting up the testing condition. As base i decided to take Ginger Revenge v 1.3.0 [Final RC2]

The system is running now for about 2 hours and testet a lot of functionalities so far. The system is very smooth i played around with some settings like cpu frequency (oc set to 1.8 GHz, governor set to SmartAssV2)

Tested so far:

Wifi

2G / 3G / 2G/3G

Cam ;) works as supposed

GPS - pretty fast

And there is a huge empty space for apps to be executed.:good:

I will report if there are new findings. :D This Evening i can tell you more about battery and if the car charging dock is "now" recognized by the awesome SkyHigh V 1.5 BM

Stay tuned.....

Hello everyone, I wanted to know if it was possible to set the clock speed of the CPU to 1.4GHz on boot without having to resort to some app, how can I do? (Kernel skyhigh 1.4d)
[Galaxy S Plus I9001 Android Development] skywalker01:
Thanks for all the offers to beta test SkyHigh V1.5, IMHO we have enough testers now.

So I'm officially closing the application for beta testing and ask anybody who didn't qualify yet not to ask anymore, from now on I won't accept additonal testers.

To all beta testers:

1. there is a confirmed bug with BT (finds no other devices) and I will look into that at the weekend

2. there is possibly a problem with cpu scaling while using ondemand governor (only min and max scales are used). I'm waiting for some logs to confirm or refute this but anybody can also test that for himself and report the results/logs to me.

@Skywalker

Again something that makes my brain burn.

Maybe you know that the GPU drivers from Galaxy W should be faster than ours? But they clearly arent.

Maybe they are better for Benchmarks like nenamark, but when it comes to Gaming (heavy games like mc3/4l) the drivers that come with XXKQM are more performant. I will make some more test with FPS Meter ( wich shows the current fps onscreen like fraps on pc)

Im very happy with v1.5 its very stable and you can make it from a Hardcore Gaming kernel to a Battery Saving kernel with only 1 App and 2 klicks. I love it.

AW: [9001][KERNEL] SkyHigh V1.4d [Updated 06-04-12] [More fixes for SD Card issue]

Im testing the kernel now for more than a good week, i think apart from the Bluetooth problem, its ready for release! :)
[Galaxy S Plus I9001 Android Development] SGS+_User:
Any changes with the gaming performance ?
[Galaxy S Plus I9001 Android Development] skywalker01:
OK, here are the findings of the V1.5 beta testers so far and the results of my verification:

1. BT doesn't find any devices

- bug confirmed, code analysed and bug FIXED

2. ondemand governor suspected to work incorrectly; only min and max frequencies are assumed to be used

- UNCONFIRMED; works perfectly on my device; please reinstall kernel and check again

3. EGL libraries that come with SkyHigh V1.4d (OUTSIDE the kernel, included in CWM install package) seem to be laggy - especially on action games like mc3 and 4

- UNCONFIRMED; though I don't play any such action games I've compared the EGL libraries of 4 different stock ROMs now:

i.

XXKPU (01.12.2011); original I9001 EGL libraries, same as in even older stock ROMs

ii.

i8150 EGL libraries supplied with SkyHigh V1.4d: all 5 EGL library files are different to all i9001 versions; significantly better performance in all benchmarks; although I don't recognize any considerable differences in everyday use, neither in positive nor in negative way

iii.

XXKQM (30.10.2012); only 1 library is slightly different to the original 2011 stock ROM distribution files (e.g. XXKPU), the 4 others are completely identical; also can't recognize any differences in everyday use

iv.

BUKPC; 100% identical to XXKQM, NO difference at all

Conclusion

: So all the talk about EGL libraries seems to be rather unimportant. Therefore I decided NOT to release any EGL libraries with V1.5, but only an optional library pack with the i8150 libraries (because these are the only ones that have at least significantly better performance in benchmarks).

This means for V1.5 that everybody can decide for himself if he wants to use the EGL libraries that come with his ROM or the i8150 libraries or even any other versions that he will just install himself.

Regarding the BT fix I will send new links to all beta testers later. Please recheck any found problems with the new versions. There shouldn't be any other differences than in BT functionality particularly since I only made some changes in the BT driver code.

Happy bug hunting,

[Galaxy S Plus I9001 Android Development] Rhonin86:
First impression new bugfixed V1.5

First report after flashing the new bigMem - variant....

the underlying GB Rom is Ginger Revenge v 1.3. Things i have tested so far:

1) BT - works for me - connected to a colleague's phones without problems :good:

2) GPS - works - first fix lasted longer as expected but the next fix was very quick

3) Ondemand - behaviour couldn't be confirmed by me - there are more frequencies used then only the max and the min frequencies

4) WLAN works too without problems.

5) Videos in max. resolution are not possible as expected - 720 x 480 work !

[Edit]~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

6) Alarmclock works also ( important for waking up from "real deep sleep" )

7) Charging with the original car charging craddle is possible - though carmode isn't activated :good:

8) During the night i switched to airplanemode and the powerconsumption decreased to nearly zero :good:

Screenshots will follow after using the phone under daily coditions....

9) For gamers (not me) Temple Run 2 could be played without any lags.... tested 1.4 GHz and 1,8 GHz !

I have attached some screenshots of antutu scores - with SmartAss2 Governor and NOOP io-scheduler 245 -1800 MHz

Cheers and have fun with the infos.....

Tested version 1.5 for a entire day and all works perfectly, great battery drain thanks also to use extreme undervolt settings.

Tested BM version for a day and 1/2, with this also no issues at all.

I'm not a gamer so i cannot put opinions on this matter, I've tested only Temple Run2 for some minutes and with the 01/Feb update of this game there's no lags at all also setting graphic quality @ maximum. (ondemand/sio 245/1401 Mhz).

I'm not sure but using stock i9001 graphic drivers TR2 runs smoothly than using i8150 drivers.

(Some people that uses my rom asked me original i9001 drivers cause of some glitches or lags on some games using i8150 drivers, same people reported me that with stock drivers problems was solved and/or phone runs better).

About 720p recording, I'm able to do it also with BM version, recorded videos plays with some very micro lags on phone, but they are played smoothly when imported on PC.

I've only one request for Skywalker: set default max clock to 1.4 GHz, phone runs fine also with this frequency and imho if someone needs more power he can do overclock as option, so at least for me for normal phone usage 1.4 Ghz is good.

Of course there are. You are so wrong and also offending once again. Mounting a device is always a command. It doesn't matter if you execute the command via shell or menu or whatever. And the mounting COMMANDS in CWM are actually called extended commands to be precisely, just look at the source code.

Well, did you look in the FeaMod thread, that's the piece that causes the trouble, isn't it ?
[Galaxy S Plus I9001 Android Development] skywalker01:
No, everything is perfect, 4000-4100 is a normal benchmark result with stock ROMs. Custom ROMs have additional tweaks outside the kernel to get even better results. You won't get these higher values with plain stock ROMs.
