Hey Pengus, why do you think LG is incapable of making a good ROM for the P990? Do you think that the Tegra is too difficult to program, or are the LG developers just incompetent? Just want to know if I should avoid Tegra or avoid LG :p
[LG Optimus 2x] stonebear:
Avoid LG.
[LG Optimus 2x] tonyp:
LG just didn't care. There's e.g. still lots of stuff tagges as "todo" in the final kernel source..

I think they just didn't want to spent money on it, as they couldn't make profit with it.

GB took them more than a year, with a giant hackfest of a kernel - ICS took even longer and as we see the kernel still isn't complete.

They pushed out the 2x to be the first dual core device - but overall it's been a disaster, with loads of problems from the beginning - which resulted in a huge price drop - they certainly didn't like that.

Their recent answer to the 2x debacle is quite another approach - they lock their bootloaders to prevent custom ROMs (see Optimus 4x, Optimus G).

So yeah, avoid LG by all means. They're not worth your money.

But - I wouldn't recommend Nvidia either. We all know Linus famous comment about Nvidia now, and it is true:

Their open source support sucks balls. (SAMSUNGS as well btw!).

Personally I hope the next Nexus phone will be from Sony with a qualcomm chip :fingers-crossed:
[LG Optimus 2x] stonebear:
Yea, me too. It seems Sony are playing fair - going by the XDA videos I have been watching recently (with that guy with the beard). :)

Ok,after two days I can say this is an amazing work by the dev. It's quite GOOD the ridiculous % of battery missed in idle state.

What a wonderful work getting the way of put the modem in idle state with no support of LG and with your own hands,it's honestly amazing.
[LG Optimus 2x] imayoda81:
locked bootloaders are ****, agree

but this phone was great piece of hw and remember it was born with 2.2 and now officially has 4.0 (and more from dev efforts)..

nvidia understood that finger very well, i'm confident we'll get better support for next tegra devices (linus was disapointed for optimus support that was simply none for years)

had one htc in my hands (X+) and have to say still nothing special after 2 years.. qualcomm is playing well and even LG is switching to that brand but... hell, i've been with this phone for 2 years now and still rocking (all thanks to those like you supporting this piece of crap)

we buy games, cars, phones and even food that is full of bugs and not yet ready to hit the streets... but we still buy it, so why they should change their behaviour ???????

Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

Food full of bugs?? Uargh, I thought it's just full of horse.

on topic: no, I don't think nvidia understood the finger, they didn't really change anything apart from doing some smart blog entries.

the only thing they will listen too is less sells, which isn't happening currently.

I have an unusual problem, when I put the phone on Silent profile, it shows the icon on the status bar but it doesn't do what it should... when I receive a call in silent mode, the phone rings! :eek: and when I use the Vibration profile again the phone rings the same way only this time along with vibrating... it is the same with almost all the sounds and notifications like emails, messages and so on... (quite embarrassing if you are sitting in a big quiet library room like I was at the time :D:silly: only thing I could do is to turn all the individual volumes down one by one to make it less disturbing when I'm in library)

I was trying to back up my phone earlier, but every time I turned on USB storage it would either fail or reboot my phone. I can't get a log for it atm, tried it a few reboots ago now, but its probs related to the fact I swapped internal and external sds.

This app causes problems? Look this:

I got this with stock kernel just now. So, it's not an app problem, it's on kernel. And I know it's because ramhack. That's why I just asked for a version w/o rh. And if I'm asking too much, I'm sorry, just thought that what I'm asking was not so big deal and other people could like to have a 100% functional phone with this awesome pengus work.

Wow, I'm sorry, I didn't see your post before quoting myself.

It's not an app problem, it's because the ramhack. Try it with default kernel and see it for yourself. Btw, if you want to compile a kernel w/o rh and need a tester, I'll be happy helping in any way.

Tried this app too and it works if you choose any other resolution than 8Mpix. With 8Mpix, the app crashed, status bar crashed, and eventually phone hot rebooted (well, sorta).

I guess it's not wise/efficient to mod the kernel if one app needs some modifications for it to run properly. I for one can live with the fact that my phone runs more smooth, even though I cannot use some app that fits my needs just perfectly.

Have you tried Camera360? Some nice HDR features... :)

Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

I reported BSODs earlier and I think I figured out the root cause. Sometimes when I unplug my phone at work, I get a static shock between my finger and the usb port. I can't believe I never made the connection until yesterday. It explains why the BSODs happen mostly at work. I guess the voltage spike causes the hardware to freak out.

BTW, the kernel is absolutely great, I was about to throw my phone out the window before this kernel :)

[LG Optimus 2x] pengus77:
Uhm, does it really find the stations ? Can you provide a logcat and a dmesg please after you try it ? If it does initialize the fm receiver then it's most probably an audio routing problem. And that one i can fix in the kernel.

Hi!

I woudn't say it's the ramhack since ramhack wasn't a problem with the HDR camera when I was using CM7.2 with symbi0sis-kernel - and I tested up to 48MB-ramhack...

Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

Mr.pengus, can we have the stable version w/o ram hack just like the old day. If we want ram hack just use terminal to key in the value we want. Just like what vadonka did for the kernel. Just a suggestion. :)
[LG Optimus 2x] swifer_lf:
or maybe do it via kow@lsky manager app.....
[LG Optimus 2x] louiscypherbr:
Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

Lol, that's why you're not getting trouble with hdr camera. It only happens with ramhack kernels at 8mp.

For those insisting that it's an issue: it works on stock kernels, and even on custom ones without ramhack, so why do you believe it's an app issue, and not a kernel fault? A really stable kernel shouldn't get reboots by app that never cause trouble with stock kernels, even more if this app doesn't have root access.

Camera360 hdr feature is fake. It's via software changes in picture, while true hdr requires that camera takes 3 pictures (1 over, 1 normal and 1 underexposed) and process them together to make 1 picture with light and dark places not over /underexposed respectively. It's a very intensive process, that uses a lot of processor and for sure video memory. That's why it freezes on rh kernels.

Again, I respect fully the choose of our dev to not release a non rh version, but as some others, I would love to have this version, and it's not a request of a new feature but a no-feature, which I believe it's easy to get.
[LG Optimus 2x] BS86:
and why should someone take interest in fixing an issue, that happens with an app, thats main existance is to make smartphone users feel like they are professional photographers?

If you are so interested in HDR-images, buy yourself a digital single lens reflex camera, thats the main equipment for taking good images. Not a crappy mobile-cam. And thats what it is, although the images taken by our P990 are quite good.
[LG Optimus 2x] LarsPT:
Jesus... the guy is only asking if it would be possible for pengus to release a non ramhack version of the kernel... why are you all so eager to dismiss the need for it? Who cares if the app is crap or not? It's just a simple request that pengus can very well say "sorry, it's too much work and I'm busy with other stuff" or "sure, I can to that for stable releases, it's not that big a deal". Why all the fuss about it?

EDIT: To BS86... and it's not fixing an app. No one is asking anyone to fix anything. Only for a non ramhack version. Me personally I would love the old rh script to let everyone decide how much ramhack they want. Not that it makes such a difference to me, as everything I use is working fine, but it's a nice feature to be able to control that.

I remember I had that same pb looong time ago when using the free version of HDR Camera+ on the official LG GB ROM. Since I bought the full version and upgraded to ICS then to JB, I never had this problem again.

So, for me it's not related to Kowalski Kernel.
[LG Optimus 2x] tonyp:
Re: [KERNEL][CM10/CM10.1][stable: 100p3 - exp: 110] Kowalski Kernel

The problem is that the new bootloader doesn't properly support the command line.

We had tested a rh script ages ago which set the ramhack amount via the command line (like vadonkas kernel), it didn't work well.

There might be another possibility to set it via the misc partition, that's one of many points on pengus long list :D

I remember also I saw many problems related to "program crash" in the release notes of this prog.
[LG Optimus 2x] LarsPT:
It simply means you can try it at your own risk, but whatever happens there's no point in reporting the problems/bugs, because they won't be fixed for ICS.
[LG Optimus 2x] brugobo:
Unprivileged userland being able to crash the kernel or force a reboot is a pretty serious security issue. It is not something to be ignored imo.

I have downloaded HDR Camera and launched an adb shell while runing it. I managed to get a live kmsg dump during initial system instability and following "hot reboot" (I was not asked for SIM pin code and I am still 3G connected, weird). adb shell kmsg dump kept working at all times even during "reboot".

Steps:

1. Installed HDR camera.

2. Configured size to 8mp as reported by others.

3. Exited app and relaunched.

4. System instability during initial preview, did not even try to take a pic. Whole system UI was blinking and unresponsive. HW buttons turned vibration feedback on when pressed (therefore detected) but had no effect. Power button worked, even displaying power off dialog. System spontaneously rebooted after a couple of screen off button presses.

I reckon the app is exercising a nvidia driver bug (nvrm_avp) so it is going to be a messy bug to fix in kernel if that is true. See attached kmsg and this quote:
[LG Optimus 2x] brugobo:
The messages "Full compaction triggered" + "Relocated 0 chunks" indicate the kernel is trying to allocate video memory and failing. An app should not be able to trigger this and kill the system, just fail and get a forced close imo. I wish I knew more about Android internals :(
[LG Optimus 2x] pengus77:
Interesting, seems from the logs that Spirit doesn't actually sets the sound card in fm radio mode. I'll investigate more but i reckon it's an easy fix (even if it means simply adding a switch to kowalski manager to do so for the near future).

Can't use terminal commands (to set the kernel command line) on the new bl. We tested and got terribly unpredictable results. I'm investigating a new common way to set the rh value that will work equally on new and old bl. This is not on the priority list now, so i'll work on it when i get the time. For now, i'm not compiling 4 versions of the kernel (old/new bl - with/without rh), so it's with or without rh and i prefer with it.

I stopped supporting ICS for various reasons: First, it's old and we're moving towards 4.2.2 compatibility. I don't care supporting 4.0.4 also because 4.1.2 works fine. Second, it's filled with LG proprietary crap and i'm not keeping the bugs in the kernel just to be compatible with it.

Thanks, this is interesting and i'll look into it in kernel space. If the AVP addressing is somehow affected by the carveout reduction, i'll see if i can move the entry point of the AVP buffer dynamically at boot depending on the carveout cut.

Yep, definitely trickster writing something nasty to sysfs. It's causing crashes in the interactive governor and/or the cpufreq core driver. Not nice at all.

Could also be a concurrency of settings from 2 different apps. Are you using something else to set the voltages/frequencies in conjunction with trickster ?
