Do i need to setup swap again after installation of new kernel?

Re: [KERNEL][CM10/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

Using kolo10 with cm10.1 on old boot loader - very smooth and for the first time phone feels faster than cm 7.2 stable. Sweet

Sent from my LG-P990
[LG Optimus 2x] FatherJony:
This is by far your best kernel mate, i can't thank you enough for your work! I/O is unbelievably fast and zram is finally useful. I checked the later with a swappiness of 90 to test the efficiency of snappy and it lives up to the name indeed, the difference with the older algorithm is night and day.

The new lmk's behavior is excellent so far. It seems to adapt according to the current running processes, and the system is fast and responsive even when free ram is fairly low.

It's kind of ironic that some nice addition to our phone come from Qualcomm. They used to be like nVidia with OSS, but they are constantly changing for the better, while nVidia is steady as a rock ;). Since i vote with my wallet, my next phone will have a snapdragon even if there are faster platforms out there by that time.

Is the conservative governor more battery friendly than dyninteractive?

Congrats on the new kernel mate, they just keep getting better and better. 010 is absolutely amazing.

Faster and at the same time better battery life = :D
[LG Optimus 2x] pengus77:
Hehehe true, Qualcomm really came out to oss in a totally unexpected way, but hey they did a great job. I had to spend quite some time to adapt their stuff to the 2.6.39.4 kernel, but it was definitely worth the effort. The new lmk is indeed adaptive, and calculates the oom values based on the active load. Glad you like the snappy zram and hope you enjoy the new interactive governor too... well aside that, tons of other subtle things and fixes happened and i think now it's reached a quite stable base to build on...
[LG Optimus 2x] natalya:
Nice stuff again!

Pengus, do you personally use Interactive or dyinteractive CPU on the newest kernel? :D
[LG Optimus 2x] hugoqueiroz94:
Pengus77, i need to install the new kernel and the std module?
[LG Optimus 2x] brugobo:
Read last few pages, he already answered that question.

He uses Dyninteractive governor and ROW I/O with 1024 readahead. You can install "Trickster MOD" app to adjust readahead and it will stay on reboots.
[LG Optimus 2x] pengus77:
You don't have to... but i suggest you do :)

About the std module, only if your router has problems with the PSP Fast mode, or if you need more reception power :)
[LG Optimus 2x] besho2222:
actually, he did switch to the "interactive" governor in the latest kernel, cause it's faster and more responsive (according to OP) :)
[LG Optimus 2x] pengus77:
Yes, i switched to interactive as "default governor" because apparently users want FAST and SPEEDY instead of stable and battery friendly. I personally use Dynamic Interactive because i like responsive and battery wise :)

Anyway i already explained this a few pages back after the release post. Go read the whole thing :)

Re: [KERNEL][CM10/ICS - OLD/NEW BL][010 - 2013/01/19] Kowalski Kernel

so this kernel is working constantly on 1000mz ?
[LG Optimus 2x] hugoqueiroz94:
If i install the psp module i need to activate using terminal emulator or is automatic?
[LG Optimus 2x] icyeye:
just interested, should we leave zRam at 18% - default or we can chose 26% ? ty
[LG Optimus 2x] pengus77:
No, it's actually using all the frequencies correctly, unlike the stock kernel handled by obsolete governors and nvidia crap...

No, if you install the psp module you'll make the PSP Full mode persistent. If you use the terminal the mode won't stick after a reboot.
[LG Optimus 2x] pengus77:
Whatever you like, you can also disable it totally :)

If you are on a CM rom though, the defaults are set in the build.prop, so i suggest you remove the line that forces 18% zram and manage it yourself in the performance menu ;)
[LG Optimus 2x] natalya:
Straight awesomeness, looking forward to that one :D
[LG Optimus 2x] Raum1807:
Really nice work with the 010 kernel.

I changed a lot around zram too last few days and I am testing my latest setup since.

Here is what I did basically:

algo changed from lzo to snappy

CONFIG_ZRAM=m

num_devices=2

swapon /dev/zswap0 -p 10

swapon /dev/zswap1 -p 10

swapfile enabled additionally with -p 100

Are you using two zram devices too now? Improves performance a bit on dual core machines.

Wanted to write about these changes next week but if you are already using the same set-up it is kind of useless to introduce.

Just let me know!
[LG Optimus 2x] pengus77:
No, one device only because my kernel in idle turns always off the 2nd core and i don't want to introduce any kind of overhead and task switching when suspending/resuming... and LOL telepathy ? :D
[LG Optimus 2x] bliizzz:
For me at 3.0v the device goes off i think my battery is worn out ,does your device turn off?
[LG Optimus 2x] SLS197:
Yes, seems that the scaling factor is wrong. The same behaviour when the first cm10 nightlies came out. Most of the apps expect mV but get back V.
[LG Optimus 2x] Andy HOT:
It happened to me too..also 3.0 barcelona ko:))
[LG Optimus 2x] kekks:
Even mine shows 3mv. Tony cm0.1 & pengus 120kk
[LG Optimus 2x] extreme79:
mine too.

3mv @27%

cm10 pengus77 rom - 120 kernel - v30b bb - new bl.
[LG Optimus 2x] black_mamba99:
I really don't care whether it shows 3mV or something else as far as the battery drain is being displayed correctly.

Earlier I had to look for the voltage in hidden menu to get the correct reading because of fluctuating readings.

[LG Optimus 2x] x_justin:
I agree, results are great! Now on TonyP's PA12, which is a great rom, but battery life is not impressive. I have no strange wakeups, but it just is a little better then it used to be. On ICS, battery life is AMAZING! (but I like to leave ICS however, hope PA or CM10 gets more battery friendly soon:D).

Look at this, 2 hours of screen on time, made some calls, played a lot on the phone and ONLY 3,5% / hour average consumption! WOW:good:

Pengus, your kernel is getting popular in various ICS threads, where people report the same great battery results.

See this screens I posted on DMX:
[LG Optimus 2x] mrjeff:
Hidden menus ?

First of all I want to thank Pengus and TonyP for their hard work and determination. KK120 rocks and my battery life and smoothness have never been better !!

Thnks a million guys !!

Out of interest, does someone know if there are more hidden menus, especially any related to USB ports. USB stopped working on my phone except for charging which is a pain in the a**.

Also, is the idea of getting Vodoo sound back on the phone totally dead? I think one of the weakest spots right now is the sound (otherwise it is getting close to perfect).

Pengus said he has no interest whatsoever in reviving a project which was messy to get to work even on GB. The github is messy full of dirty fixes so i do believe he said no.
[LG Optimus 2x] Nardocf:
Sorry for the offtopic:

My usb was like this but i send to lg and they fix it without any charges. So, if your phone is on warranty try this. Dead usb is real pain indeed :( .

I apologize for his answer, next time we will give you a long and detailed answer within 2minutes.

[LG Optimus 2x] sangriaman:
Hi tony. I´ve been using foruns and xda for way too long to start pointless fights with anonymous smartass guys, even less with great developers like you.

Seen too much of this things happen, to care, really.

But the funny thing with this "phenomenon" is that it's never the asked person that gives that answers (as you can see here - that person was polite and very helpful). It´s always someone that gets pissed off.

And another funny thing is that they dont have time to help, but they do have time to post fabulous posts.

And BTW, dont presume that i want someone to reply out right away.

Eventually, when i get to a pc, I WILL google it myself, if someone couldnt help yet.

Why do you need a pc to google something, when u got an android? U could just open your browser, tap search and type something like "viper audiomod android" read it, do it, and its done, u need some sustain to do it?

hiya Pengus77

with my first Device, a Samsung Galaxy SII, i use a very good Kernel, called Dorimanx 9.14. In this i have a function, thats mount intern and extern SD-Card automatically, i dont must use any app was mount automatically. And here i can use it with PC AND Device at the same time. Its realized in Kernel

With the P990 when i mount SD-Card, i can use only one at the same time. It is technically possible, that we can integrate automount with access to both SD-Card in p990 too?

Its just a idea, but i think this is a great idea...
[LG Optimus 2x] remygo:
i experienced yesterday a 0% shutdown at 14% ... but couldnt reproduce it and didnt happened again.

why do i get low battery info at 14% and 4% instead of 15 and 5?
[LG Optimus 2x] tavoc:
if you connect your phone with MTP then you will have exactly this behaviour.
[LG Optimus 2x] pengus77:
UMS is not supported by Google, neither by me. MTP is the right way and now also Linux can access it. No real need to stick with UMS at all.

I'm seriously thinking to actually disable it (as on AOSP) because it creates more problems than it solves.
[LG Optimus 2x] bliizzz:
Hey penguss, just wanted to ask should I give logs about this or you are aware of the bug, the device shuts down automatically after 50%,and won't start until a battery pull:(.

And yeah battery is shown 3.0v is this normal or is the battery worn out ?(tried using the multimeter shows 3.8~4.0v

Edit: cm10.1 unofficial v60, kk120
[LG Optimus 2x] massimo69:
Would you mind stating rom and kernel in your post? With the information you gave we can only guess that you really need tr@p to sort out your problem.

On another note, yesterday I got an N4 :D. I will not be leaving you guys as this community makes me feel @ home. I ll be helping out developing, well if tonyp and pengus77 let me, as I will be keeping my p990 as a backup. I am the official spoiler :D.

Actually I will be running a lot of tests in the next few days regarding battery usage in different situations so we can get a good benchmark to start with.

I know you mentioned Xperia ZL... what do you say about Xperia ZR? It's powerful as Xperia Z/ZL with smaller 720p screen. Seems quite good to me. ;)
[LG Optimus 2x] massimo69:
I do have to mention that hardware wise and speed wise with the same amount of official support the p990 would be as good as any device if not better. (Forget Ram) screen here is awesome p990 i mean. :D

I am using v30a. As far as app goes, check in the settings not to get updates too often. I set my apps to get updates every 4 hours. Check weather updates too, everything that needs internet access. Another very important thing is the quality of signal. Our phone will drain a massive amount of battery if the signal isn't good.

do you want to know when the thing without UMS gets really messy ???

When you have to recover some deleted files using a pc.. mtp isn't supported at all for surface scanning.

(got crazy on a lumia wp7.5 to have some important files back for a friend that deleted them earlier.. impossible task)

Don't know if there are some utilities in userspace for android.. for wp there are not :)
[LG Optimus 2x] SLS197:
Hi,

it is the same way flashing the a rom. Make sure you download the correct zip for your bootloader.

flash the zip file with TWRP or CWM recovery.

Just to be save, wipe dalvik cache and cache before rebooting.
[LG Optimus 2x] Kyrandialegend:
Use just external SD card to save docs/pics/...etc, so when you need to get data back the extSD card id ready to be inserted in a PC card reader. UMS not really needed IMHO.
[LG Optimus 2x] imayoda81:
you have to do things before (people starts thinking only after problems occur) and not any phone has external sd card.. ext card is one of those things that they are trying to cut off from devices. Just look at the nexuses.

Cutting UMS is a big industry mistake, that's what i think :)
[LG Optimus 2x] MetaIIica:
I think that too [MENTION=301201]imayoda81[/MENTION]

I think MTP or PTP are absolutly crap. When you use UMS, so we have all options from your own explorer and the filehandling is better than MTP or PTP
[LG Optimus 2x] Anurag pandey:
+1

That's why i always use UMS from twrp
[LG Optimus 2x] machoman1337:
Hey pengus, afraid I won't have a chance to enjoy 100p6 as I've finally upgraded to a Nexus 4. Anyways, have a beer or something on me ($6.77 CAD = 5 euro), and hope the next release turns out well. Grazie for all your hardwork especially the CM10 rom :)

to above: Yes, UMS is faster than MTP or PTP too, also it's compatible with car stereos. MTP is annoying, the only advantages are that you don't need to manually toggle it on when you plug into a PC, and the phone isn't locked out of the files when plugged in.
[LG Optimus 2x] imayoda81:
not to mention that MTP is somewhat a M$ standard and on linux i still have some weird beahviour accesing files all the time (many times folders are empty and tree is incomplete missing many files and folders until reconnection) :)

Experimental Release

Hey guys, managed to get some time in the last couple evenings :p

121 is up and happily ready for download. Changes are few, but notable:

1) Battery voltage reporting is fixed, so hopefully you won't see anymore the 3mV thing and it will display the real value ;)

2) I spent quite some time trying to add a light sensor to the rom itself and i actually managed to have it working, but the work is not worth the result. Apparently there is something fishy going on and my sensor kills the other ones, so i switched point of view and went back to the kernel side. We now have a real working auto brightness directly in kernel space ! But i wasn't happy about that alone, so i implemented a sysfs interface to alter the auto bri table directly from user space :D

To see the current alc table:

cat /sys/class/backlight/aat2870-backlight/device/alc_table
0 = 9
50 = 10
100 = 12
130 = 13
160 = 14
200 = 16
250 = 18
300 = 19
400 = 21
500 = 23
650 = 25
800 = 28
1000 = 32
1400 = 39
2000 = 43
3000 = 60

Where the values on the left are the light sensor LUX values, and the ones on the right are the ALS brightness values. The sensor values are fixed, while the ALS allowed values go from 5 to 70.

To overwrite the auto bri table:

echo "9 10 12 13 14 16 18 19 21 23 25 28 32 39 43 60" > /sys/class/backlight/aat2870-backlight/device/alc_table

There must be exactly 16 values in the string, separated by a space, and must be within the 5-70 range. The kernel will default to the hardcoded table if the values are wrong...

wfd is already working on a new kowalski manager that will add a nice ui to change the auto bri table... soon... very soon... ;)

Well then, have fun. It's all up in the XDA FileServer folder linked in my signature ;)

[LG Optimus 2x] pengus77:
