?? Sure.. do you know how multicore works?

a single core can compile the complete ui as fluid as necessary.. the lagghiness is caused by a wrong settage of the governor.. i'm explaining.. governor chose what freq is necessary to complete a charge.. if freq is too less, you have lags.. if is too high.. it's increase poeer consuption for nothing..

4 cores doesent means more power, but only, 4 cores :D

The advantsges of multicore is when you have a lot of parallelizzable threads, as you shoud know, a single thread isn't parallelizzable, but,, you can compile MORE THAN ONE with out of order executions.. it means, more cores = more parallelizable works..

Games needs fast cores.. since those has BIG threads unparallelizable..

P.s. is unusefull to force on the 4 cores.. you aliment 4 cores for nothing ;)

depends on what governor

Nope

Yes, I switch to performance governor and set it to max only when doing benchmark test and playing 3D video games and I just keep it to pegasusq and set it to full range (min: 200 max: 1800) in the rest of the time.

And there is no problem when doing Quadrant Professional Benchmark test since I can have a value of 7600 something nor with Vellamo (value of 699) and I only have problem when testing with Antutu since everytime I push the frequency to max and set governor to performance the frequency of 1.8Ghz only last for about a minute before it turns down to 800Mhz so everytime when the test reaches to the end I always have a poor benchmark value compare to the score of a Note 2 in the chart.

Same thing with playing 3D games, after about few minutes, I can see that the graphic becomes laggy.

I know a little bit how Multi Core system works, but not much! All I know that this phone has four cores and I would like to see them enabled rather than disabled. I also know that when I used Perseus (past tense) it lagged like hell in comparison to Stock kernel. I did change the settings back to like stock, which removed lags around 60-70 % but not all.

However, the term 'lag' and 'fluid' differs from person to person, some people say Android is super fluid, and iOS is laggy, well you can bet I am not one of them :rolleyes:

Could some one attach the perseus 32 here I need it ver6 badly
[Galaxy Note II Original Android Development] iba21:
Ok.. one question as an answer.. why turn on 4 cores if it isn't necessary? all L1caches + core's units will be alimented for nothing.. same performance with more battery drain :D

The lagghiness is caused by a bad governor settage.. if you want i can share you my values.. but.. i cant create a package right now.. if you know how to put a script in init.d folder, i'll give you MY setting.. and sure.. i can create those as your specific values.. with a faster hotplug or/and a better ramp up of the core

P.s. no i cant autochange values.. it's possible but script will be loaded for total of the time, so, it will block the standby condiction with an increasing of wakelocks "istructions"

Ubderstand?

---------- Post added at 11:28 AM ---------- Previous post was at 11:24 AM ----------

Dont know why cores comes back to 800mhz.. probably thermald values.. so.. when cpu goes to an high freq, system force a lower freq to prevent a phisical damage of the chip..

Probably you donc't read the correct value with the app.. the correct is readed only by the matherboard, and sure, it has a root access over any operations!

I can see how this will be a very stupid question, but can I use the CWM zip and install the kernel from TWRP? I prefer the TWRP recovery so I don't want to change to CWM just to install this. And since I'm on a different computer, can't install the drivers and such for tar flashing.
[Galaxy Note II Original Android Development] Old faithful:
I would sure love to see USB Mass Storage Mode reinstated as native in the next version of the kernel. IMO, it's the biggest problem with Android 4.1.1 and on so far. I truly cannot fathom what Android OS architects were thinking when they removed this basic functionality. I mean, removing direct, reliable, non date-changing file transfer between the device and a PC? If I hadn't found a hack to allow me to do that, I would have returned the device.

I am already frustrated with the tyrannical file save locations paradigm and am constantly struggling to find where the apps or the OS hides MY files (that includes settings and every personal stuff I create from the device), I hate having to spend so much time hunting for my personal files and moving them to folders on my own choice on my external sd card...

Anyway... If that's not determined by the kernel and I'm completely off topic here, don't hesitate to correct me ;)

[Galaxy Note II Original Android Development] Meowdib:
Mine wouldn't get past installing the zip. Trying toggling the verification. Meh. I found Philz CWM and it worked great. Glad you got it installed.

Edit: Now that I think about it, it ended up being a corrupt download, but I couldn't mount my storage from TWRP correctly, so I had to use CWM.

I've set my GPU script up perfectly, however it only works when I manually execute it via script manager.

I've moved it into the init.D folder as Omega supports it. I've set the permissions to: RWX - RX - RX.

Will this execute on bootup?

I've changed the steps, to allow smoother transitions. Before, on default steps it was staying in the lower range as nothing was taxing the GPU. This was evident during certain games, there were slowdowns. I've also changed the voltages following the instructions in the first post.

N7105 support

AndreiLux,

thanks soooooo much for being the first XDA developer to support the N7105. I have one from Portugal and i realy hope that in the future more ROM and Kernel developers follow your example!!

Again, thanks so much!!

By the way the last version 25.3 is working very very well!!

I overclok mine to 1700Mhz and the GPU to 733Mhz and the phone flies!!!!!!

P.S: i made a simple script (gpu.sh) to change the default values to overclock. But even so i need to run it manualy in each reboot. How to put this echo commands in init.d? I cant find init.d in /etc

[Galaxy Note II Original Android Development] garyd9:
I think it might be useful to isolate the problem. This isn't a problem related to fast dormancy. I see the same thing on my device with that app - it's either a sqlite issue or a file I/O issue.

For some reason, when sqlite tries to open the database file with a stock firmware, it works (even if the file doesn't exist) while the same operation fails when Perseus is the booted kernel.

Why would the kernel impact that? Not sure... At the lowest level, file i/o is controlled by the kernel. However, Perseus is based on the stock source, so it SHOULD work the same as stock (and I didn't notice any changes to the file i/o code in the commit log for perseus.) It might also be a permissions thing set up in the ramfs (doesn't seem likely.) Not sure.

I don't have JB on my i9300, so I can't check the same operation with the current Perseus kernel on there - but it works fine running the last ICS persues kernel.

Strange, huh?

It's also not a major problem as people generally don't go toggling fast dormancy on and off all the time. Set it with a stock kernel, flash perseus, and be done with it. It's just really odd that this would impact only a single program...

Take care

Gary

[Galaxy Note II Original Android Development] notegalaxy:
What did you set your up threshold and down differential to? The first post says it shouldn't be higher than 99-up threshold. But default values are 90 and 10. 99-90=9. This makes no sense. Am I missing something?
[Galaxy Note II Original Android Development] AndreiLux:
It works for me on the I9300 on JB, and what most of you already know, what is basically the same kernel. Also somebody in the general forum here reported that it worked. I don't even touch sqlite or anything i/o related, so I have no idea.
[Galaxy Note II Original Android Development] Suicidal Chicken:
I use 70 up and 15 down differential. I'd suggest checking the meaning of the phrase (Don't mean to be condescending, it's beneficial to figure it out yourself.)

The up threshold is the percentage of load. If it's 99, it wont ever scale up; which is why it's not advised.

I am currently using it, plugging the male usb connector to the HTC wall charger. Still doesn't seem to charge..
[Galaxy Note II Original Android Development] lainemac:
That might be because that charger is only 1 amp instead of 2.
[Galaxy Note II Original Android Development] Aumkar:
The Note II wall charger is rated at 2A. HTC will be lower. Also, the USB cable matters for charging. Samsung is very finicky about it's cables, and the stock cable that comes with the phone is able to deliver the current, while cables such as the blackberry stock cable can't.

That is interesting cuz I have been using the HTC wall charger to charge Note II. But it doesn't work with the OTG cable.
[Galaxy Note II Original Android Development] Aumkar:
It may charge, just not very well. My Griffin travel charger barely charges the phone. USB 2.0 on my desktop is a whole different story. Maybe it's cuz I'm using the phone, but the cable definitely matters.

[Galaxy Note II Original Android Development] iba21:
some free informations about chargers

1) phones has a chip witch controls the ampere charged

2) phone's chip decides the ammount of ampere, that's to prevent any damage of the battery.. why? Battery is a BOMB!

3) the better condiction is with original charger with original cable.. the impedence of the cable changes the ammounts of ampere, so, chip decrease those

4) don't know why you would use an otg camble to charge the phone.. it's used to connect usb objs

5) if you don't use the original charger, the other ones will have a slow charge, 2A output too.. why? Chip sees the ramp of the voltage of the output is different than the right, and do his magic

6) voltage charge is not linearry, if you have a li-ion battery, charge needs to change his output voltage as fast as needed with a correct logic witch is increase the speedness of the charge.. sure.. chargers are ELECTRONICALLY.. not as the older chargers

so.. when you don't use the official charger + official cable, you could have a slower charge

P.s. note2 battery has 11Wh.. Htc one has 8.5Wh.. you understand why we need more amperes!
