Are you saying that our p990 coud be smoother than a gnex?! Are you serious? If it's true you will become my god!
[LG Optimus 2x] pengus77:
Just hinting that at the moment i'm running a set of tests and "apparently" we just leave the gnex in the dust on all fronts (including ram, yeah) lol

P.S. On cm roms we'll never get the crazy antutu/quadrant scores that may come out on ics... the proprietary LG stuff in the stock rom is way more optimized that what we have, but hey, can't have everything right ? :)
[LG Optimus 2x] pengus77:
Zram active or not ? Do you have swap installed ?
[LG Optimus 2x] pengus77:
No, the modules are not designed to shut down wifi at all. The default behaviour is to enable cam mode and a 1:3 dtim skip ratio when the screen is off, while the conservative module enables psp mode in the same situation and with the same 1:3 dtim skip ratio. When active they both use cam mode, which is also known in broadcom-land as pm_fast mode, and that should be supported 100% by all manufacturers.

Just a few questions: your router uses openwrt ? Is it in N or G mode ? 5 or 2 Ghz ? 20 or 40 mhz ?

And i want to clarify one thing..yesterday i said screen did not automatically sleep...well..actually it sleep after intended time...but when charging..it doesn't..is it intended too?after aprox 12 hours using i can clarify that battery life is very good indeed..performance sometime have small lag when typing after wake up...but i think it's still acceptable..considering i have 'ram eater' apps...:(

OK, this night wiped data, chace, dalvik.

Reinstalled your kernel for old BL (but not re-flashed PA zip).

No heavy battery consumption due to CPU to 1GHz every few seconds.

[LG Optimus 2x] svein01:
Probably some application that kept a wakelock on the display. The fact that it worked now suggests to me that the kernel implementation works as intended. I could be wrong, but situations like this (and the question posed by someone a few posts ago, asking if screen could be kept on during flash video playback) - in my understanding, anyway - depends entirely on how the individual apps implement their wakelocks (ie, requests to keep the device awake and not go to sleep). The kernel will just respond to these requests and act accordingly.

I'm sure someone with deeper knowledge will correct me if I'm wrong :)

Thank you for your work.

I try your kernel in DJango 1.2 but wifi don't work.

I read other users have the same problem.
[LG Optimus 2x] FatherJony:
Zram is set to 18% in build.prop so i don't think that setting it in Android has any effect. You could always comment the relevant line out (put a # in front of it and save your build.prop) before disabling it in the settings. The line is:

persist.service.zram=18

You can find the build.prop file inside the system directory. I also think it's unlikely that zram would cause reboots, it's considered stable and a part of the mainline kernel, but then again, it might create conflicts with something else so you never know.
[LG Optimus 2x] x_justin:
Yeah I have the same problem. When I walk away from home, it disconnects from wifi:confused: When I turn off the router, it disconnects too:fingers-crossed: No just joking, I think it is because pengus adjusted the power levels of the wifi module a bit to make it more energy efficient. However, for me it keeps connected even with a very low signal. Have you enabled the option to avoid networks with bad signal, in the advanced settings?
[LG Optimus 2x] Ferrum Master:
I can confirm, wifi automatcally avoids poor networks.

Re: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][011p4 - 2013/02/03] Kowalski Kernel

Hi guys.

One question..

The "tx power" and the other wifi settings on kowalski manager how can we use them for better results

For example: a large or small tx power number?

Awake power manager--on or off

Psp power saving mode--on or off
[LG Optimus 2x] Rayman96:
Odp: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][011p4 - 2013/02/03] Kowalski Kernel

lower tx power if your u are near to your route. psp is saving battery mode but no one every router like it. I enable power management when awake.

Sent from LG 2X using Tapatalk 3 Beta
[LG Optimus 2x] massimo69:
Well the answer isnt that simple, it all depends on your router.

I for example use power tx 19, Awake on and psp on.

the best solution is to test with your router. If pings dont go trough when the phone is in deep sleep then turn off PSP. Same goes for the other settings. Test and try to find the best TX power that suits your router.
[LG Optimus 2x] bree1:
R: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][011p4 - 2013/02/03] Kowalski Kernel

tx power influences the strength of the signal only during transmission and no reception. used to conserve battery power only when you use the phone as a WiFi hotspot. It has nothing to do with the distance from the router and saving battery while receiving.

[LG Optimus 2x] massimo69:
I believe that to conserve wifi hotspot power you have the hotspot power management. SInce it is a radio I assume that the tx power of the antenna will affect both transmission and reception. ;)

[LG Optimus 2x] Buccio:
Ops so sorry guys, i don't know this. Now i've understood :)
[LG Optimus 2x] FatherJony:
Vsync has always been supported in the p990 kernel and in every other tegra2 device. What the new kernel is lacking in order to get the full project butter experience is triple buffering. Triple buffering is a technique that increases framerates when vsync is in use at the cost of some added memory consumption and input lag.

Disabling vsync would improve the lowest framerates, but it would also introduce allot of screen tearing, so IMO it's not worth doing.
[LG Optimus 2x] Ximo F. Verde:
Found tonyp's mention on the issue http://xdaforums.com/showpost.php?p=36895554&postcount=2687

He says:

'70% of project butter? More like 0%.

We don't have vsync (at least not the new 4.1 vsync timing), no 60Hz and I think no second backbuffer for triple buffering (and thus are only double buffered).

So all in all none of the JB 4.1 features.

It's not a low memory isse but an issue of missing updated binaries.

I think we'd need new hwcomposer and gralloc blobs as the ICS hwcomposer we're using is outdated and probably doesn't support the new apis. (Maybe the headers would suffice, I don't know).

As we do all know the probability of LG releasing updated binaries there won't be Project Butter on the P990.

The chance of Nvidia helping out goes to zero as well..'

In the same thread (a page later) you mentioned that fps should match the display's refresh rate. As far as i know this is not the case since we r talking about 60fps and if im not mistaken the screen's refresh rate is 72Hz.

A few months ago i joined a discussion regarding the refresh rate/fps matching suggestion, still cant figure out if this is valid for this discussion..
[LG Optimus 2x] FatherJony:
The comment about matching fps with screen refresh rate was an oversimplification to make the post more accessible. In reality, to avoid tearing the next frame should not follow the previous frame to the screen buffer sooner than the screen's refresh rate. So if your screen has a refresh rate of 72Hz and the following frame rushes to the screen in a time shorter than 1/72 sec you will get tearing. So you don't have to match the screen refresh rate, you just have to wait for it. Still, since fps drops bellow 60 are perceivable by the human eye, it's also desirable to have a constant 60 fps for a smooth experience.

Btw, we do have vsync, that's why there is no tearing in ICS and CM10-10.1. I haven't looked at extended vsync so i don't know what more it adds to the table but as long as there is no tearing vsync works.

[EDIT]

I am not sure about the 72Hz refresh rate for the p990 screen. It might be true with Froyo and gb, but i am almost certain that in ics it's set to 60Hz. What leads me to this guess is that spreading 60 frames to 1/72 moments a second should produce stuttering, and while there was plenty of that in gb, it's minimal in CM10 and mainly the product of frame rate drops due to cpu time sharing or complex animations.

[EDIT2]

I didn't look at the code so i can't be certain, but after reading a little bit i think that by extended vsync Google meant that the vsync timing was also extended to the CPU via that 1/60sec heartbeat. Correct me if i am wrong, but i doubt this is a special driver feature (it's probably implemented in the framework).
[LG Optimus 2x] Miwer:
I must say, I like GSam Battery Monitor better (formerly Badass Battery Monitor) - I think it's easier to read, and it can also show apps and kernel wakelocks (number of wakelocks and for how long) and a lot of other stats.

I also have a wifi drain issue. With the phone sleeping, suddenly it just starts draining - no wakelocks or anything else keeping the device awake. I usually notice it, after I turn on my phone, and check the graph. Funny thing though - the drain stops as soon as I turn it on.

Only wifi is on - phone is in flight mode, as I currently don't have a SIM card installed.

Using PA build 4 and kernel 11p4, bb V30a, new bl

PSP on, Hotspot PM off, Awake PM off, TX pwr 12dBm

I have not made a logcat/dmesg/last_kmesg, sorry (also lumberjack hangs on exporting dmesg) - I'm just waiting for the next release of ROM and kernel, but if anyone have a suggestion as to testing conditions and when I should make what kind of log, that would be great.

Known bug is that wifi drains a lot when it disconnects from the AP (goes out of range) and stays on. I suggest you disable wifi when you're around. Also, as another battery-saving hint, disable in the wifi advanced settings the "Network Notification" thing. It'll keep scanning aggressively when in suspend.

About 3G, it's a drainer on all phones guys... on this one even more. CM doesn't really support all RIL messages yet and there's nothing i can do about that in kernel-space.

[LG Optimus 2x] Miwer:
Yeah - I think that is part of my problem. I have noticed drain problems when leaving home/work, however it can't be the only thing, because I sometimes experience it even when I'm in the same location, suddenly the drain just starts until I turn it on - I will see if I can somehow make an illustration of the problem and some logs.

The app called Sentry (available in Play store) is supposed to disable wifi, when not in range, and enables it again in set intervals to see if there's a connection, and leave wifi on if there is - if not, turn it off again. Seems to be working ok, but I disabled it for now, in order to test this problem a bit more.

Great tip - I have disabled it now, and will see if things improve :)
