I just realised that if you do not overclock, the default frequency is 1015mhz , meaning if you don't overclock you are stuck with single core.

I think the frequency required for activation of 2nd core at 1040mhz is abit too high. can you please lower it to 900+mhz

Some of us do not overclock the device.
[LG Optimus 2x] Flix123:
An additional non-oc version would be great!

The 0.4 kernel is good, but are there really problems with 2nd core at 1200 mhz?
[LG Optimus 2x] shpapy:
Regarding 3) I cannot reproduce this here on my phone. The 2nd core works fine either with 1040MHz and 1216MHz if it is really needed (i.e. SystemPanel with a lot of scrolling up/down).

Regarding 8) I will look into that, but since installing is not as important as actually using the phone, it is not that high of priority (as for example BT and / or 50hrs lag).

As for BT: I'm pretty sure it does work now, although I don't have access to any BT device right now. So let's see how it turns out. :)[/QUOTE]

Hello All,

after 22 hours of usage these are my findings.

the B.T is working much better but still unstable. i can make couple of phone calls and afterwards the car kit disconnects but the phone still thinks its connected. only if another call is made he drops the b.t

if i leave the B.T in standby i.e. no calls, it lasts for 5-10 afterwards the link is broken.

the phone doesn't lag at the moment after 22 hours of usage, with previous kernel it would lag at 22 hours already, and after 40 a restart was mandatory.

i will keep monitoring him.

the 2nd core is working fine! @ 1200(the problem was with monitoring as i monitor via adb)

in regards of the installation of apps, i just mentioned it as a side note, imo it could take 2 hours to install something as long as it wont lag afterwards.

no doubt this kernel is way better than previous versions.

p.s. wifi and 3g are fine.
[LG Optimus 2x] shpapy:
update 2:

after 46 hours of heavy usage the memory leek seems to be fixed!!!!! i got 100Mb free memory and the phone works, yeh there are some minor noticeable lags but really minor ones, no app get stuck or something like that.

the B.T module is not functional.

2nd core works good as stated before.

also i tried now N.F.S and there are no lags (with N.F.S open i get about 35Mb free ram) and still all is o.k.

on idle (bg sync , 2 push mails accounts and some other stuff) -14Ma - 16Ma. so the drainage of the battery isnt the best in the world but still its fine with me as i have ext. batt.

update 3: 53 hours of usage all good!!!
[LG Optimus 2x] Dac0908:
Plays nice with Flexbomb R2, battery life still great. :)
[LG Optimus 2x] Dac0908:
Interesting. I'm not experiencing any slowdowns or similar problems when free RAM falls under ~100 MB, which inevitably happens sooner or later. It wasn't a big issue, just annoying - and happened on (I think) all ROM's and kernels so far. Glad to see that bugger gone :)
[LG Optimus 2x] krajova:
I am happy with the smoothness. Its amazing! I can't even bring myself to test ICS or anything else, since I can't run the kernel ...
[LG Optimus 2x] shpapy:
but there is the B.T bug so unless you dont use B.T i would recommend to switch kernels.

try this one

all is working 100%

[LG Optimus 2x] dr4go:
Thank you two. I'll try to work something out... Just to mention why there is no new update for such a long time: girlfriend, university, two jobs and hobbies.

Although... sadly...

- I really hate the sources they (Nvidia / LG) are providing us - that's also why I truely believe / feel so much more comfortable with CM9 now (using Owain builds). The motivation would probably be back if the sources would suck less the next time they are releasing something to the wild...

- and... there are so many talented developers active in developing kernels right now. I always tried to remain as close to the sources as possible and just picking a few valuable cherry picks... my eager when trying something the last two times ended up in reverting the whole thing after developing for more than a week per commit [not publicly released works].

[LG Optimus 2x] Lo_RaT_PeNaT:
dr4go, thanks for your work, we need developers like you who make it possible to improve our abandoned device, a question of your kernel, I noticed that there is some visible lag and with the lookscreen, any suggestions, to no time since froyo I think of that, a salute and thank you very much.

[LG Optimus 2x] dr4go:
Thank you for the nice words. :) I've also noted the visible lag in the lockscreen - still not sure why that happens, but I will try to figure that out.

I already began the v0.2 developement and it should be available soon. I'm still not sure which way to go regarding the swap thingy though... I'm currently fiddling around with it.

I really dislike compcache - so don't expect me to implement that as default option. So I'll probably add a swapfile... opinions?

How big should the additional swap be? First I thought to go with 512MB, then I thought to go with 256MB - now I believe the best to go with either 384MB or 448MB. What do you think? :)

Lastly a personal opinion: I can't find any reason why anybody should or would abandon the device. Yes, of course nVidia wasn't (and still isn't) fast in the developement of the Tegra 2 Android / Kernel stuff, but imho this device is currently one of the best if you also respect the value you get for the price.

Thank you all for the warm welcome.

[LG Optimus 2x] Lo_RaT_PeNaT:
first, I totally agree, we have one of the best devices on the market, just missing the final push, I'm sure it came, my opinion is that 384 mg would be enough, although it would go to a higher figure but would begin to test out there. A greeting and thanks again
[LG Optimus 2x] shpapy:
Sorry but why swap? It's slower and lowers performance

Also you can the results spica has with it. thanks for the kernel I'm Using it and its great never had a crush or boot or stuck or anything simply works from the get go. I'm also plying many games ( big holiday sale these days) and everything runs very smooth
[LG Optimus 2x] hakankarani:
I agree p990 is still one of the best available in the market.
[LG Optimus 2x] dr4go:
Why? It's simple:

- Compcache reduces RAM performance (obviously, because the data needs to be compressed/decompressed when accessed the memory)

- But more importantly: Compcache eates your battery faster (also obviously, because it needs more cpu when accessing the memory).

So I'll either go for swap or no swap/compcache at all. Because I like to use the 512MB of RAM I have at no additional cost at all.

That said I also find battery more important than the swapping performance. But we will see how it turns out. :)

For those who want to enable compcache I will provide my kernel with the "swap notify" patch.
[LG Optimus 2x] shpapy:
thanks for the details ,

what ever you will implement i will test :-)
[LG Optimus 2x] Striatum_bdr:
Just to give info, with compcache 371 MB no OC, I have 5400 with Antutu so the same as without cache.

Can't say for battery.
[LG Optimus 2x] blakki73:
The same for me. I can say with precision that for me battery life has not changed with swap.

"Good job drago, please still develope your kernel in this way. Don't take care to people that write a kernel just to make a good quadrant score . I tested your kernel with hell rom (20o based) and i reached 24 hours of hard testing without any reboot and i still have 50% of battery remaning. I also have a very good ram management without any poroblem."

ps: little adding by me

I also tested your kernel and it works very well, i can't say anything about battery life but i can sure tell you that OC/OV settings work very well. Pimp my cpu not also well, i had a galaxy s2 and tegrak app is better. Thank you! (ps: please if you will add nice features like caching and ram compression can you please insert a menu or an app to enable/disable them? because i had very bad experiences with ram compression and maybe my needs are different from yours :D)

you are the best!
[LG Optimus 2x] dr4go:
Updated first post to v0.2. This version should have been the first release though. :D It should be a lot better than v0.1.

Thanks for the feedback regarding v0.1.
[LG Optimus 2x] el_charlie:
Please help me out,

If I only install the kernel, do I get compache????

Explain that.

I know that using the swap enabler, er, enables SWAP, but I don't know about compcache.

What do you recommend???

I do play and do multitask a lot.

Cheers!
[LG Optimus 2x] dr4go:
@ ryaneu: Have you already had the chance to test a few schedulers? Thanks for the feedback.
[LG Optimus 2x] dr4go:
No, you don't get compcache. I added just the support for the needed notification mechanisms if anybody wants to enable / play around with compcache.

I'm not sure regarding the swap thingy, yet... I didn't had the chance to give it a good testing in the last three days. But you can always easily activate / deactivate the swapping mechanisms with the provided zip files.

Currently I have swapping enabled - just FOR testing. I just invested my time in the creation of v0.2 and the new installing scripts (also for the zips), because so more people can test and provide useful feedback.

Not sure if I will leave it enabled or disabled, yet. ;) Probably more information regarding that in the new year. :)
[LG Optimus 2x] carburano:
Great! New kernel...

Sunday evening I will start building DjangoManouche 0.4!!!

Thanks man!
[LG Optimus 2x] el_charlie:
Well, I just flashed it and also the SWAP enabler.

So far, so good, but it's too early to say it for sure.

I'll give it a day or two. My nandroid is there just in case xD.

Cheers!

Something to add:

Pimp my CPU asks me to delete a file. I've never used the app before on that ROM (I'm pretty sure). Do I need to delete the file???

That means the kernel is overclocked by default???

Please answer that.
[LG Optimus 2x] el_charlie:
I've found a bug.

The battery information shows the values wrong. They are multiplied by 1000.

For example the fully charged value should be 4,2 volts (4200 mV). Now it shows 4200 volts (4200000 mV).

See the screenshots.
[LG Optimus 2x] KillerbeeNL:
+1 ... high current voltage :D

using the 0.1 version for a couple of days and not a single reboot or BSOD

battery performance is normal so not complaining about that.

for me stability is number 1
[LG Optimus 2x] KillerbeeNL:
with 0.2 i lost data connection?

maybe it is my provider but right after installing new kernel I lost it.

is default clock setting at 1400 MHz?

device was getting hot and I had to pull battery.

reverted to 0.1
[LG Optimus 2x] ilos:
same for me i got : unknown baseband on stock froyo v10d
[LG Optimus 2x] dr4go:
If you want to specify other options than those provided by the zip file you will have to delete it, yes.

I thought, that it was clear with the previous changelog line ("Changed min/max cpu frequencies"), that other frequencies are used. So yes, it is overclocked. Refer to the updated changelog.
[LG Optimus 2x] dr4go:
Right you are... Refer to v0.2a. ;) Thanks for the information.
[LG Optimus 2x] dr4go:
Where do you see this message regarding the "unknown baseband" thingy? Do you also have the stated problem with v0.1 of my kernel?

Are you, KillerbeeNL, also using a froyo version?

Strange that I never saw this message / I never had any data connection loosing problem. Maybe the v20L sources aren't 100% compatible with Froyo - some of the other kernels out there still use a v10E as base with some backported source updates.
[LG Optimus 2x] KillerbeeNL:

[LG Optimus 2x] rexren:
A little bug?

The battery indicator lost almost 40% power after rebooting the phone.(from 60% to 20%):confused:

Both happen on v0.2 and v0.2a.
[LG Optimus 2x] el_charlie:
I finally deleted the OC file and with Pimp my CPU crated a profile with 1100 to have a little OC but maximize battery life.

I must say that on idle, the power consumption I'd pretty low. When going to sleep the phone was on 100% and after waking up I only lost 1%.

Of course when using it the battery drops because of the OC.

I don't have issues with wifi or mobile data.
[LG Optimus 2x] shpapy:
I flashed the new version without the swap patch and no oc lets see how it works previous kernel had memory leaks as I posted previously
[LG Optimus 2x] dr4go:
Do you have the link to thread somewhere lying around? Would be interesting to read.
[LG Optimus 2x] dr4go:
Honestly... there is no way I could think of a kernel could accomplish such a behavior. Although there was a bug with the battery mAh displaying in v0.1 and v0.2 the battery indicator shouldn't have taken note of it.
[LG Optimus 2x] dr4go:
Still more information needed as I don't have any single problem with the data connection and / or wifi. Especially if you use a Gingerbread ROM everything should work just fine (I've also tested a few Froyo ROMs without a single glitch).

And by the way: Happy new year to all of you! :)

Is there any reason to cap the overclock at 1.4GHZ? I'd much prefer to be able to set my phone to 1.55/1.6Ghz.
[LG Optimus 2x] Stefan Gündhör:
I'd even prefer 2.0 Ghz :D:D:D:D:D:D

Man this isn't a PC, this is a phone :rolleyes: I think above 1,4 GHz will likely cause instability (seen this in spica's kernels with 1,5 GHz capability), but I guess dr4go can tell u better.
[LG Optimus 2x] Mungulz:
I don't understand this argument? if it was just a phone then why aren't we all using Nokia 3315s? It's about making the best use of what you have, and 1.55ghz furthers that belief in my opinion.

I don't recall any instability with Spicas 1.55hz kernel, but I may have been lucky. Besides, how am I supposed to show up Galaxy S2 users in bechmark competitions at only 1.4ghz?? :D
[LG Optimus 2x] Stefan Gündhör:
Nokia 3310 is still the best phone in the world :D

Ok for getting high benchmark results I can understand this but it's kind of a sham all this xtra high overclocking, because for everyday use you won't OC your phone to 1,6GHz as you would have to recharge it every few hours.

And then the high results @1,6 GHz are quite pointless, as you won't get this performance in everyday use running lower frequencies...
[LG Optimus 2x] PAIIITET:
dr4go

What do you think, what the optimal parameters are needed, if I use the swap?

/proc/sys/vm/swappiness 60

/proc/sys/vm/vfs_cache_pressure 25

/proc/sys/vm/dirty_ratio 10

/proc/sys/vm/dirty_background_ratio 5

Now I use the swappiness=60 and a heavy load swap takes about 25-30 mb
[LG Optimus 2x] dr4go:
Actually no. There is no reason. I didn't have time to invest on frequencies / voltages, yet. So I only took the latest settings of imperticus' NeoBlaze kernel.

Regarding OC: With my HTC Desire HD were 1.92GHz possible. But as gueste already said: This wasn't ever my default setting for everyday use...

But please also don't forget, that my old phone was a singlecore Qualcomm processor. I have no clue how high we can go with the nVidia Tegra 2 dualcore cpu.

We'll need to figure that out. ;)
[LG Optimus 2x] dr4go:
You could also wait for the next version of my kernel. :D
[LG Optimus 2x] dr4go:
Already waited for this question. And I have a very interesting / informative article for you: http://www.imoseyon.com/2011/01/sysctl-tweaking-for-faster-longer.html (read also the follow up)

Personally I have only experience with swappiness and vfs_cache_pressure. And I would lower the vfs_cache_pressure indeed to ~20.

Regarding swappiness=60: that is WAY too high. Even on desktops I would never leave that default value. But if you consider, that the SD card is slower than hard disks you really should lower the swappiness by a whole lot. I'd also start with 20 or even lower.

The higher this value is, the more the swap is used. And... WE don't want that. It's simple as it is... For background apps and stuff like that, sure... why not? Otherwise it really will decrease your performance.

EDIT: Also refer to: http://www.imoseyon.com/2011/04/why-swap.html Not everybody is the same opinion... ;)

what do you think so we enable the swap?

thanks.
[LG Optimus 2x] KillerbeeNL:
so I installed v0.2a all is very smooth but it overclocks my phone @ 1.4 gHz by default so I edited the volt-scheduler to set it @ max 1015000 Hz (stock speed) for better stability and battery life.

I do not care for overclocking and Antutu showoff to other users with same or different phones :D

make an GOOD impression to others by playing games etc. without sudden reboots and bad battery life to Samsung/iPhone/HTC users with a rock stable kernel like this and they will envy you :D

@dr4go maybe release a stable stock speed kernel for other users who do not want to edit the volt.. file

also different kernels with 1100mhz an 1200mhz to serve users who want to overclock a little should be on some users wishlist :D

Great work dr4go !!
[LG Optimus 2x] dr4go:

Yeah, i passed the 50 hrz now with 2 days on batt.

i don't have any kind of monitor installed on the phone ,just monitoring with my eyes on purpose to see behavior.

i havent changed anything from the version that you provided besides gps tweaking and diffrent build.prop so i really think this version is quite stable even with the OC to 1.4 and the UV that you have pre-set.

i haven't tested out GTA since i don't own it but NFS runs very smooth and same goes for shadowrun.
