beh stupid sorry for the double post
[LG Optimus 2x] Benee:
Do you found a way to switch between otg and normal usb mode?

When I tested it (wow nearly a year ago) I needed to switch between these modes while booting up. Never finished the patch to 100%.
[LG Optimus 2x] Harsh:
working on porting usb host driver, still waiting for my HOST/otg cable to be delivered, so have not tested myself anything yet.
[LG Optimus 2x] tr@p:
Can I use otg cable from Nokia C7?
[LG Optimus 2x] skylinegt77:
id say yes, since usb stuffs universal... :)
[LG Optimus 2x] Benee:
I abandoned the work on this because of some hardware limits. I have something in mind. Anyway still hope you succeed because otg would be neat, hehe.
[LG Optimus 2x] kickokim:
I have a standard otg cable, what should I do to test?
[LG Optimus 2x] Harsh:
download my host2 debug kernel. from previous link in last pages. Connect your OTG cable, and then connect your USB stick into that. While doing that keep logcat on, and if possible pass me logcat (paste it on pastebin, here only link please)

Can you connect mouse to USB host, and see it it works?
[LG Optimus 2x] kickokim:
Ok, I'll do that and send a dropbox link if it's ok.
[LG Optimus 2x] kickokim:
I can't get any logcat app to work... anyway nothing happens when I plug in usb flash drive.
[LG Optimus 2x] Harsh:
I guess I will have to ask benee on what he did to enable USB Host before booting up.

Can you connect mouse to USB host, and see it it works?
[LG Optimus 2x] kickokim:
Tried mouse, still nothing!
[LG Optimus 2x] Harsh:
Guys, today I will be going to Italy for week for holidays, so no new builds until I come back. I will post OC kernel before I leave
[LG Optimus 2x] baliriot:
enjoy your holiday Harsh, have fun! :D
[LG Optimus 2x] temasek:
Go enjoy yourself. Next month is my turn, going to Hong Kong with my family. :D
[LG Optimus 2x] hei1125:
Hong Kong is where I live in:).

I advise you visit the Peak to enjoy the awesome view of Hong Kong.

And also you may go to Ocean Park, compare to Disney Land I think Ocean Park is better.
[LG Optimus 2x] temasek:
Thanks

I'm pretty sure my children will love it. :)

Also India definitely on my list thanks to you sir!
[LG Optimus 2x] CarloIT:
Wonderfull idea "Bella vita party" in Venice :)

Sooner or later You have to come back :D
[LG Optimus 2x] Harsh:
OC version up, on my Google Drive, Mediafire and also on Dev-host.

Build build-OC-2505

same as stock 2205 + pmem disabled(Owain's suggestion, credits Benee)

[LG Optimus 2x] ciwek90:
Alright. Thanks mate. :D
[LG Optimus 2x] wapz:

[LG Optimus 2x] Harsh:
Back from Italy, it was nice. And driving felt awesome :D

here is new update on stock Kernel.

And you have already manage to get an update! Respect! :P
[LG Optimus 2x] tonyp:
OT:

Why is driving in Italy awesome?

I always thought people want to drive in Germany as it's the only European country without a tempo limit.
[LG Optimus 2x] Thief777:
@Harsh

You came OTG cable?? to test the host.

my cable was not working, waiting for when it's the other (
[LG Optimus 2x] Striatum_bdr:
Because Italian people drive worse than French :p
[LG Optimus 2x] tonyp:
That's possible? :D
[LG Optimus 2x] Harsh:
because I had Indian feel. In Italy speed limits are not to be followed, in germany they worry too much.
[LG Optimus 2x] skylinegt77:
in germany you have autobahns with no speed limit.

side note, i dont think any country can have worse drivers and car manufacturers than france... XD
[LG Optimus 2x] Striatum_bdr:
Bla bla, bla... :D
[LG Optimus 2x] tonyp:
Hehe :D

What I DO like when driving in france is:

a) the tempolimit (many fatal crashs in Germany because of this damn 200km/h+ drivers)

b) the fact that you don't have to change the lane when driving onto a highway - the leftmost lane will get "closed" instead of the new one. Nice idea!

What i DONT like:

a) highways are costly

b) Why do you keep blinking left while overtaking? That's strange.. hehe

c) no handbrakes while parking because you need to be able to push my car around? WTF dude :D

d) general driving style :p

We are waaaay OT - but this had to been said :D
[LG Optimus 2x] skylinegt77:
no handrakes? seems to me i broke the rules many times then... :D
[LG Optimus 2x] Harsh:
Guys still USB OTG not fully ported, so will not work. I am trying to port it from nvidia source, and implementing LG fixes into that, whole USB driver, but am unable to compile properly, so have to always fall back.
[LG Optimus 2x] reginickneo:
Oh gosh this is that I'm waiting for.
[LG Optimus 2x] Thief777:
I too am waiting)

already ordered usb hub and a couple of things.

[LG Optimus 2x] Najmuddin NP:
There's a bug.. turning off the soft key lights makes the phone un usable.. vadonka has fixed this in his kernel... ( using the latest stock ).
[LG Optimus 2x] Najmuddin NP:
USB tethering isn't working :(
[LG Optimus 2x] Harsh:
I know about this problem, but I do not intend to revert it back. It is due to led 2 step turn off.

I am aware, drivers still not fully fixed. Working on it.
[LG Optimus 2x] Harsh:
Sorry for double post. New build updated

Changelog:

build 1006 Stock & OC

Linux Version 3.0.34

Patches from NVIDIA for cpu control (power saving)

Lowmemory killer from linux 3.4 ported by vork (thanks benee)

download links in OP and also in my signature.
[LG Optimus 2x] Thief777:
how things are going with OTG Host?
[LG Optimus 2x] Harsh:
very bad. Porting drivers from kernel 3.1 nvidia source is not working good, always giving troubles.
[LG Optimus 2x] skylinegt77:
we bielieve in you :)
[LG Optimus 2x] Najmuddin NP:
Any advantage leaving that bug on?

Your OP mentioning USB tethering fixed.. Was excited to see a 3.0v having it fixed..:(
[LG Optimus 2x] Harsh:
Two step led shutdown is new implementation, and its good one.

So instead of turning away from it, better way would be to find solution screen responsiveness with led off new way.

And last time I checked usb tethering was working for me on windows.

And you always have wifi hotspot as backup :D
[LG Optimus 2x] RohanAJoshi:
Trying latest built..

.

in ur last kernel (including all ics kernels available) all core ie cpu0 and cpu1 are stay awake all time.

but in cm7 if the frequency of cpu0 goes upto 800mhz then only cpu1 gets awake and turns off quickly after need.

will this possible in ics ?
[LG Optimus 2x] kickokim:
That is one of the major differences between gingerbread and ics. I think ics handles multiple cores together (like on a modern pc os).
[LG Optimus 2x] Najmuddin NP:
With which kernel did u try tethering? Stock or OC ?

Wasn't working with latest stock..
[LG Optimus 2x] Harsh:
I always used stock. Will try it again later, as I do not use windows cant test it as i want.
[LG Optimus 2x] mkchan:
Hi sir just want to know if fast charging is included in your kernel...

Thnks!
[LG Optimus 2x] Najmuddin NP:
Do let me know after trying it out..:)
[LG Optimus 2x] Harsh:
Yes it is included, you need to know how to enable it, or easy use Owain's ROM.

My MacBook pro in Apple care right now, has graphics glitches, replace whole logic board including processor. I guess I should name myself gadget_breaker.

I will let you know if I test it.
[LG Optimus 2x] owain94:
You did break a mac!?

Really!?

I admire you!
[LG Optimus 2x] RohanAJoshi:
how to change vibrator strength ?

and how increase cpu speed at boot or by deafault ? ie not any program, cause at boot time cpu taking 600mhz speed. that causes slow boot.
[LG Optimus 2x] Harsh:
Vibrator strength patch is not included, so no increase there. And it should boot at 1ghz by default. What are you using to check this booting CPU frequency?
[LG Optimus 2x] kyanox:
Nice Kernel, phone seems snapy and no fc's so far. Will let you know how battery does.
[LG Optimus 2x] aragorn7:
@Harsh, any chance you would be willing to port your excellent kernel for the su660? I've been using your latest one on mine, and it's working great.

I imagine it's a matter of changing key assignments (the three buttons for the su660) and the partition table (su660 has 10 instead of p990's 9). I wish I knew how to do it myself but obviously don't, so I'm respectfully soliciting for your help!

Thanks in advance!
[LG Optimus 2x] Harsh:
Will look into it. It should be not so difficult I guess. kernel config change mostly.
[LG Optimus 2x] ykin:
I have tested your kernel with miui v4. The touch screen was lag unfortunately.. so I could not test further.

I faced the same problem with vandoka's beta kernel and miui v2 before.

Thanks for your effort. :)
[LG Optimus 2x] der.einstein:
Hi there,

I hope HARSH will be back soon! Thanks for your fantastic development.

Please, don't give up on USB OTG/host!

Cheers...
[LG Optimus 2x] uber_:
Awesome work my friend! Realy good job! :)
[LG Optimus 2x] Thief777:
I also really need OTG host)
[LG Optimus 2x] Harsh:
I will not give up on that. Well keep trying
[LG Optimus 2x] bliizzz:
Hey usb storage isnt working...

M currently on egb build 5
[LG Optimus 2x] Harsh:
For ums you need Rom support. Try owain's Rom. It would work on that.

[LG Optimus 2x] Harsh:
It's causing unexpected problems in compiling. Will try it more, but currently just setting up compiling and updating to latest Linux version
[LG Optimus 2x] Spineshankumb:
Don't worry Harsh your Kernel is really beautiful ;)....So had you some results with OTG? or nothing?
[LG Optimus 2x] fuxmen:
Recomenn any program to control CPU on this kernel or just use ICS settings ?
[LG Optimus 2x] imayoda81:
bug

i think i've found a nasty bug.. latest oc at least on owain's latest

last night i was enjoying some music in Apollo.. then i reallized phone was very very hot (was set to 1200MHz).. in performances cpu settings actual frequency was stuck to 1200 and never going down..

opened terminal and looked for a stuck process eating cpu time but (as phone was very responsive) nothing was over normal cpu usage..

tried then to kill everything but cpu clock was still stuck at maximum..

uptime was about 24h and dmesg told nothing strange than usual cpu shutdowns and usual touch bla bla..

a full reboot fixed that..

:O
[LG Optimus 2x] Harsh:
Hi guys, here I got something to ask from you all. I have two kernels with exact same source, just bit change. Can you all test and let me know which performs better in real life tests. Battery and performance both. And dont go by date, one is compiled 5 days ago, which i tested for 5 days and its ok, and other I compiled here.

Finally a new kernel :D

1607 it's very snappie, thanks Harsh!
[LG Optimus 2x] ykin:
Harsh-kernel-1607-P990 is very nice. :fingers-crossed:
[LG Optimus 2x] aragorn7:
@Harsh:

As an attempt to provide a more "objective" analysis of what you requested (i.e. comparison of 3.0.36-1007 vs 3.0.36-1607), I did a small experiment using AnTuTu benchmark v.2.8.3 on my o2x su660.

How the test was done:

Scores are AnTuTu custom test for just database IO

ROM: owain94's Domination #80

Lagfix patch applied

Test was performed five times, fresh after each reboot to remove any influence from caching effect. I observed that repeated testing after a single boot led to artificially higher numbers (data not shown). I was interested in baseline performance.

All IO scheduler were set to sio, except where indicated with asterisk were set to vr.

Earlier kernels (your 3.0.34, wkpark's 3.0.8) were added in the test as reference

Results are as following (average ± SE, n=5):

Some conclusions I drew:

Both versions of 3.0.36 kernels had slightly better IO performance than your previous 3.0.34 (~7% higher score)

Both versions of 3.0.36 kernels had IO performance that were not statistically different from each other

As expected, OC versions consistently had higher scores

vr scheduler consistently had better IO performance than sio scheduler (at least in 3.0.8-wkpark kernels; ~9% higher score)

Final comments:

Obviously, it depends on how much faith one puts on the benchmark. But based on this, it does seem clear that both versions of 3.0.36 are improving the performance (at least in IO). If people are indeed observing better performance from 1607 than from 1007, I am guessing it's not IO related.

An interesting side suggestion -- could you consider adding vr IO scheduler in your future versions?

Anyway, hope this helps you in your development. Appreciate all that you're doing for us all!
[LG Optimus 2x] tonyp:
Impressive work aragorn.

@harsh iirc he's waiting for a SU660 version, do you still have that on your table? :)
[LG Optimus 2x] fuxmen:
is this a good idea to use setcpu with this kernel?
[LG Optimus 2x] eyronic:
On the safe side, it's better to use the one on the settings to change the frequencies than using an app.
[LG Optimus 2x] fuxmen:
but how can I limit screen off freq?
[LG Optimus 2x] eyronic:
It's automatically done by the kernel. The screen off freq is always the lowest freq. I think. XD
[LG Optimus 2x] fuxmen:
Dont think so, because 216mhz is to low to for example: playing mp3, recording trip with sports-tracker, and lot more stuff when screen off. But anyways It's don't bother me if battery life would be good :)
[LG Optimus 2x] Harsh:
Thanks. That's really good comparison. And sure will add vr in future. Thanks.
[LG Optimus 2x] Harsh:
No kernel for SU660 is not in works. But i guess they(SU660 users) can use Harsh kernel or any other kernel with Owain's latest ROM, with hybrid bar enabled.

EDIT: sorry for double post
[LG Optimus 2x] aldyu:
Hi Harsh, why's there's no ramhack in your kernel?
[LG Optimus 2x] Harsh:
Its already there same as default CM kernel (32 MB). It is just not adjustable, because its a stock kernel, which should boot on all devices, and run all possible games.
[LG Optimus 2x] ykin:
I was using the kernel 1607 and was perfect until tonight.

I was recharging my phone and I found the screen became very lag suddenly.

Although I've flashed the kernel 1007 and wiped cache and dalvik-cache, the problem persisted.

I faced this problem with miui v2 and Vadonka's kernel before. The problem's gone with LG Star driver patches.
[LG Optimus 2x] aldyu:
Never encountered any lag using kernel 1607 with xxMrHyde's latest rom.
[LG Optimus 2x] Harsh:
Updated new kernel build-1907, NO-OC

Changelog:

Linux Version 3.0.37

Improves SIO scheduler for flash storage.

Added V(R) I/O Scheduler. (select if from AnTuTu CPU Master)

other various fixes (thanks to vork[benee] and faux123)

@ykin

I never had lag problems, could you check how many apps were you running? or some other programs must be leeching up your memory.
[LG Optimus 2x] ykin:
I have tried your new kernel build-1907, but it still has the same problem for me...

Thanks anyway.
[LG Optimus 2x] ppp0941:
I used both 0620 and 0719 kernel in owain's 80 kang

and they are both very lag in scrolling

problem solved when using javis v7...
[LG Optimus 2x] rzlatic:
to resume: quite a lot random hot reboots with both 1607 and 1907 in the past few days since release. 1006 is still a piece of rock compared to later versions.

anyhow harsh, you're doing an excellent work we all appreciate! :good:
[LG Optimus 2x] Harsh:
Reboot issue should be fixed in next release. But lag issue I can't fix as I don't experience any. My scrolling is super smooth and all runs great.
[LG Optimus 2x] ykin:
Please could Vadonka give a hand on the screen lag issue.. :rolleyes:
[LG Optimus 2x] mo8175:
I don't have any lags on Paranoid Android.
[LG Optimus 2x] punyategar:
Sorry for noob question guys.

Having flashed the kernel, how do you use usb mount storage?
[LG Optimus 2x] Harsh:
If you are using Owain's rom, when you connect usb it should come up as in gingerbread, easy as that. Else just go to settings/storage and from menu select usb connections, in there tick on mass storage.
[LG Optimus 2x] flat__line:
Thanks for the great kernels.

A question though: I found the phone dead after letting it charge for the night (had to remove battery to restart it). Is this kind of problems due to the kernel, the ROM (this case NOVA 1.1) or both?

Thx,
[LG Optimus 2x] TjekDig:
Since Owain's 80, I had quite a few hot reboots with 1006 OC. 1607 reduced the number of hot reboots and so far I've only had two with 1907. (one just after installation and one when stressing maps and navigation)

Rock on!

...
[LG Optimus 2x] punyategar:
Thanks. Im on paranoid android by tonyp. I'll do that.
[LG Optimus 2x] slebit:
Will cpu spy ever work with this kernel?
[LG Optimus 2x] Harsh:
@slebit Yes. It will work. Need to ask benee about that patch, will apply it later.

Currently enjoyed new release, Linux 3.0.38, probably not reboots fixed.

http://www.mediafire.com/?uozce3kh8dge2rq
[LG Optimus 2x] slebit:
Just installed your 3.0.38 kernel. Working nice so far.
[LG Optimus 2x] coolacrille:
Thanks for this kernel. I was very close to giving up on ics because of soooo much lag. Then I tried this :) Alm ost no lag at all since flashing this kernel.
[LG Optimus 2x] fuxmen:
Try ParanoidAndroid :) Heaven't seen such smooth rome out there :)
[LG Optimus 2x] bech5:
Tanks for this great kernel Harsh!

A few issues though; GPS is very buggy, well, basically it is not working at all in 1907. It works fine in 1607. Don't know what has changed. So i reverted back to 1607. The overall smoothness also seems better in 1607 for me, 1907 seems a bit more buggy/laggy.

The boot time seems a little slow. Out of all the ICS kernels, Spica's by far has the fastest boot time. What is different about the boot-up process in his kernel? Would it be something that could be improved in this kernel?

The battery life is excellent though! :) The 1607 seems to be an otherwise really good fit for me so far with Nova HD 1.1.0. (1006 won't even boot for me, so can't say anything about that).

Cheers! ;)
[LG Optimus 2x] Harsh:
My friend you got very sensitive O2X :(.

1006 should probably boot up on every devices which could boot up previous versions of my kernel, or those which can boot versions later than 1006. Mate you should try 2107, here is link. http://www.mediafire.com/?uozce3kh8dge2rq.

PS: GPS works perfect(lock under 5 seconds) for me, maybe you need to check ril, I use GPS navigation on Owain's 80 with my kernel on daily basis, as O2X is my primary phone.
[LG Optimus 2x] bech5:
Tanks man. Running 2107 now... so far everything is running smooth, no bsod and the GPS is working again. My O2x does appear to be a bit sensitive. I cannot boot up with benee's kernel either. But at least it seems to be sensitive in the sense that it's either running pretty much flawlessly or not running at all! :cyclops:

[LG Optimus 2x] Striatum_bdr:
Yes using it too and didn't report but some random BSOD during normal use still occur with 21 version.
[LG Optimus 2x] tonyp:
Don't you think harsh will tell you when he has news about OTG?

Every page the same question over and over again. You have no advantage of asking him every 2 days, but you're risking to annoy him too much to continue working on that.
[LG Optimus 2x] Harsh:
Guys usb otg hit roadblock as we using old drivers in 3.0.y kernel.

And currently have to develop android app for university project, and i don't know anything about app devlopment so learning it these days.

And me using same 2107 no reboots yet since day i compiled, but i don't listen to music either so don't know. Will check it, good if you can put logcat app running when listening music. Amd get me logcat if anything strange happens.
[LG Optimus 2x] flat__line:
2107

Very smooth experience using 2107 with NOVA HD (virtually no lag with apex or go,

heavy multitasking memory profile) but

found phone shut down (phone was left sleeping)

seems hard to reboot (also to recovery: it shuts down and I have to start it up)
[LG Optimus 2x] jalal.mustafa:
can i install this kenal on my SU660?
[LG Optimus 2x] Harsh:
Only if you are running owain's rom with hybrid bar. You will need to use on screen buttons if you install this kernel
[LG Optimus 2x] TheBo:
i'm reporting too a huge battery drain while on idle...I fully charged my phone during the night and now I'm working , from the 7 AM (unplugged at 100% battery) till now I just woke up the phone 5 times just to see if there are calls or messages and the battery is now gone to 8% after only few hours .

Used to see if there were any wakelock and did not find any, just the system stats says "awake all the running time". (the screen was off). Hope it helps:good:

-------------------------EDIT---------------------------------

Confirmed it was a Kernel related issue.... back to normal with a different Kernel, no system changes nor apps uninstalled
[LG Optimus 2x] Gjot:
It's possible to make a 48MB RamHack on the OC kernel? How can I do??? Thanks
[LG Optimus 2x] Harsh:
Only way to do it, is by compiling kernel yourself from source. 32mb its already there in my compiled kernel.
[LG Optimus 2x] Nova163:
Hey Harsh,

My phone is pretty slow, especially when launching applications, and I can't seem to figure out what's causing it. Freeing up more memory doesn't help at all, and using the OC version doesn't change anything either. Is there anything I can look at?

Thanks!
[LG Optimus 2x] xstokerx:
is there anything in this kernel thats broken
