Develop Bugs

Skype and CM7

Hi everyone, my girlfriend has a Galaxy Gio and I just convinced her into installing a Custom Rom. Now, the problem is that I don't know wether it performs well with skype because we use that a lot. I am thinking of installing CM7 because of the customization possibilities. I hope there is someone who has already installed it and who can tell me it's bugs and how it performs on Gio. I am interested in battery life as well and I would like to know if you had SOD with it. But the skype part is really important. Thank you for your responses, have a nice day!

Use phiexz CM 7.2 rom, it has no bugs and its very fast & stable, i use it myself, i also have skype on it and it runs good without any bugs.

You know... phiexz has created his own web... -.-
The link is this one :
phiexz.com
I think that is down for maintance...
It is already on nightls, aroma installer and very more improvements ...
If i helped you... press the thanks button

Thank you both, I installed Phiexz's CM7 and so far so good both with skype and overall performance. One problem though, the battery drains much faster or it looks like it does. Any tips for improving this ?Besides that everything is good. Thanks for your help!

Wait for this site to be enable...
www.phiexz.com
The most recent update of cm 7.2 was in 10/7/2012...
I have been using that for a while... and battery does not drain.

I think he's testing/optimizing his ''cloudfare'' so his site can be reached while its offline, but having the download center mirror.phiexz.com or something would be nice when the site is online, but its says welcome new user and when you close the message it comes up again, not that you could download from a server that is down
its good he's doing maintenaince, atleast you know his site isn't a ''dead end'' , he's working on it.

Yes there is a good way for improving the battery live, when you are not using the phone, go to Cyanogenmod Settings - Performance - CPU Settings then put Min CPU to 122 and Max CPU to 320, then put the governor to POWERSAVE. Then when you use your phone put everything to normal.

powersave uses almost 100% the lowest minimum frequency, so setting 122-600 should be good

[KERNEL] AndromadusMod [CM10.1][27/04/13]

This is kylon's AndromadusMod kernel, originally for Saga / Desire S, but compiled by me from source for our Vision. Massive thanks to the Andromadus team and to kylon for his awesome mods. Built with the Linaro toolchain.
From kylon's original thread:
Code:
Only experimental [COLOR="Red"] (=)[/COLOR]
Features:
sync with Andromadus: Apr 17 2013

dynamic file sync (=)
UnderVolt / OverVolt
The kernel is already uved (post #3 )
vmstat, MM, shmem updated to linux 3.4
Tweaked gov and scheduler to work better on android
some optimizations here and there
expire time about each entry of scan results: 15 *Hz
force AC charger for unknown chargers(like carKit)
ck1 patchset
enabled clean cache
enabled zRam
NLS-UTF8
enabled power collapse to save battery(?)
Removed almost any debug message to improve the performances
USB OTG (=)
NTFS r/w (=)
CIFS (=)
Power saving when the wifi is off
More RAM for us
what i forgot..
Bugs:
Same as Stock Andromadus
USB otg: usb sticks are not working
Click to expand...
Click to collapse
I know USB otg definitely won't work, and at the moment I haven't used LZO kernel compression. I'm not sure if there will be "more RAM for us", being as the original kernel was for the Saga, which had more RAM in the first place. Other than that, all the visible changes, such as governors, I/O schedulers, OV/ UV, etc., appear to be working.
Downloads:
At the bottom of the post you can find the flashable zip, I have also attached the original Andromadus 3.x kernel (Original.zip) in case you want to revert, the only thing I've changed about this is I've added CPU idle PM support, this should help with battery life but it's nothing drastic, and other than that I've left it alone.

Great Job! ill for sure be testing this out!

Thank you so much, this kernel looks very promising, will definitely test it out.
Update: It doesn't feel as fast as the original kernel, however the Mod kernel does give me 1MB(one) of additional user accessible RAM.

This could be flash over the 10.1 Andro or on the 4.2.2 AOSP?
Thanks

It's originally for CM10.1, so I doubt it'll work with AOSP, especially due to the nature of the test builds (for this reason it's probably not compatible with build 20 or below either). That said, it's worth a try. I don't know if there are any mods of the AOSP kernel, I haven't got much experience so I probably couldn't mod it myself, but I'll look into it

Thanks for the feedback, I would try out some of the included governors, there's quite a few! I personally find dyninteractive more responsive and smoother than the default SmartassH3.

I tried both kernels on perf governor like i always do, and the Mod kernel i significantly slower, for me at least. I suspect that it's due to the LZO compression.
Anyway, it's good to see another kernel Dev, i really appreciate your work and i look for ward to your next release.

good work:good:
if you need help just pm me and i ll try to help you as best as i can (even if i m a still a noob xD )

He said this kernel is not using lzo and i don t think the kernel compression can affect the performances
it can only affect the boot/reboot/shutdown time
"more ram for us" is working because it is a generic tweak, every kernel/phone can have it

Thanks for pointing that out. I have reverted to the original kernel as the Mod kernel is really slow in comparison. The original kernel with the added CPU idle PM support has significantly increased my battery life.

That's interesting :silly: not gonna lie, I didn't realise it would actually make a difference. In menuconfig, under CPU Power Management there's an option for CPU idle PM, right next to the Governor bit.
I'm personally finding the kernel alright in terms of speed, I guess I could try the latest Linaro tool chain and/ or look into some other kernel stuff, although I'm hardly an expert

Also, just to point it out. I think you have accidentally packed the Original kernel inside the Mod package.
Anyway, i'm looking forward to your next release, this kernel looks very promising, i think it just needs to be polished.

Just to point out one more thing: I'm definitely getting stronger WiFi signal with the Mod kernel, I'm also getting less disconnects when using 802.1x networks.
I am gonna do a full wipe and try this kernel again, and hopefully i will get the speed advantage this kernel technically should offer me.
P.S would you be kind enough to compile the original kernel with CPU PM idle support and also force ac charge? Thanks SOOOO much in advance.

Haha no you don't need to, it's something I enabled in the kernel before compiling. You will only notice a difference when the device is sleeping, so try leaving your phone on (aeroplane mode if possible) overnight, and you should notice very small battery drain. Basically you don't need to do anything

[Kernel] [CM9 - RC2 & RC3] honeyx 7up 2.6.35 kernel [for better battery life]

Due to some requests via PM´s I decided to make my kernel finally public, but remember:
This kernel is a personal kernel for my private use, so it´s only containing the tweaks I´m also really using
It´s the older 2.6.35 kernel basing on latest 2.6.35 sources from Arco, so only use it with Arcos CM9 RC2 or RC3 or a custom ROM with 2.6.35 kernel
This kernel is not filled with a lot of governors and schedulers, but only the ones I´m also personally using.
I have made this kernel because non of the custom kernels worked stable for me in the past, even at stock voltages. With this kernel I´m able to run at extreme Undervolting rock solid.
So this kernel was created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So why I decided to tweak this older kernel rather than going with 3.x kernel?
- Because this kernel is giving me a much better battery life than the 3.x kernel, is running rock solid and also because I don´t really need the new features added into 3.x kernel.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered lcd voltage
- slightly lowered standby / deepsleep voltage
- Battery life extender
- Fixed 100% battery notification after charger unplug
- 377MB RAM
- NO-OP scheduler as default scheduler
- Lulzactive governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added 518, 633 and 902 MHz (new)
- screen off frequency set to 518 MHz max.(new)
- some more voltage tweaks
- no other compilation tweaks just to make the list longer
With this kernel and a new battery my SGW can last up to 7 days in standby. This is without WiFi and Mobile Data. With the stock kernel I got 3-5 days. It´s also working absolutely stable and smooth for me without any issues.
So if you run into some issues that are/were also discussed i the CM9 Bug report thread, don´t blame me for them.
other suggestions:
- enable KSM
- enable 16bit Dithering
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.
Just as a note. Should you encounter the white screen bug in some apps, this is because you whiped the cache in CWM Recovery after flashing the kernel. To fix this go into settings -> apps and delete data and cache of those specific apps.
Credits are going to:
- Arco (for his great work and sources)
- educk (for helping me doing the first steps)
- Christopher83 (for his great commits)
- ivendor (for his tweaks)
- Ezekeel (for Battery Life eXtender)
----------- 18.08.2013 -----------
- added frequencies
- incrased RAM
- lowered screen off frequency in Lulzactive
- some voltage finetunning

I have tested this before with rc2 and I have to say battery life was very significantly longer compared to hurtsky 2.5 + QAsR v2.3. However, the white screen issue persisted in 2 of the apps I used the most, namely boat browser and Gmail so I have opted out again. But if you guys don't care about white screen, do give this kernel a try

Yeah, kernel 2.6 is always better battery life... i recomended it
- screen off frequency set to 768 MHz

What mean of that ?
is we get trun off the screen it auto lock on 768Mhz ? it's not deepsleep any way CMIIW

This is the max frequency the clock might rise to if the screen is off but for example an app or a service awakes the phone from deepsleep. So it will not drain so much the battery if the phone gets awake for some reason and if you undervolt your cpu, you can reduce the consumption for such a case even more.
This is preset in the Lulzactive governor, which Christopher83 fixed to make this working, so it´s only related to this governor, which is also my default governor.

So when in screenoff the phone only maximum can use CPU clock at 768Mhz
Yeah i get it. .thx for explain it

I think arco might be able to help you fix the white screen. Long back skull kernel experienced the same and acro helped him to fix it.

Uhm, well I´m not sure this is exactly the same because Keff (Woohooo..) is modding the 3.x kernel for CM10. But thanks for the suggestion. I will aks Keff first to not to bother Arco in the first place. It will be for sure interesting what caused it for him.
Just to clarify some things about the white screen bug. The one I described in my first post is not the real white screen bug, but only what happens to some apps after whiping the cache in CWM Recovery. This can easily be fixed like described above and will not bother you anymore.
The real white screen bug came all of the sudden (without whiping anything before). So for example you opened facebook, everything was fine, but a few minutes later by relaunching facebook you got a white screen. The procedure to get rid of this was the same as I already mentioned but with the difference it happened again after a while.
So well I have had this issue with facebook too in the past, but it´s gone and now even not happening after whiping the cache in CWM Recovery. It´s not gone because I updated the rom (still using RC2), but because facebook updated their app.
Edit:
I already found what you was talking about. It´s called the white noise issue where you get a white screen by turning the screen on, so it´s not the same.

Mind you: This is battery saving rom. It is meant to have low game performance. It MUST have a lower gaming performance than those v3.0 kernels. If you want gaming, this is not for you.

Yes, this is a battery saving kernel, but why should it have low gaming performance? Just because it´s optimized for low consumption in standby and because you can undervolt it? It´s like you were comparing an older Pentium4 against an Intel Atom CPU and saying the Atom must be faster because its newer. Or by comparing a Atom against a 286 CPU and saying the 286 will be faster than the Atom because the Atom is more battery friendly.
Sure, it´s not optimized to get the highest scores in benchmarks, but the games I´m playing once in a while are running totally smooth.
The newer releases of CM9 might be of course faster in games, but not just because of the 3.x kernel, but also because Arcos ocessionaly is updating the GPU drivers.

Thank you for correcting my ignorance. :laugh: Maybe I'll give the kernel a try and tell more about that

Honeyx, I hope you continue to develop and share this kernel in the future because I decided to start everything over from scratch because of your work here. I love this kernel. I get so much better battery life now. If you would ever consider adding Lionheart in the future, I would be very grateful. Is there any way to add Row or does it require kernel 3? Thanks again!

I may add some tweaks in the future, but this may take a while till I have some spare time to test them. About adding other governors...well I tested a lot of them but finally decided to use Lulzactive because it was the most battery friendly governor in the one hand and because there is also the Lulzactive app you can use to tweak it to your needs. So for example tweak it that way it behaves like for example Lionheart. I also tested the ROW scheduler but it wasn´t as stable as I presupposed to be. So the best compromise between stability and performance was to use the noop scheduler. It´s nearly as fast as the row but way more stable.

LoL. I´m quite sure with extreme undervolting you can still save some battery juice even while playing action games on this device. Beside this it´s not the CPU or GPU that consumes most, but the display and its backlight LED´s.

it is for battery saving but for me its not good to play with games cuz playing for like 40-60 minutes consume 60% battery ? lol
thats quite alot and might burnt up my battery life.

So did you thought it will consume just as much as being in deepsleep????????? The kernel is tweaked to consume less in deepsleep and in daily use but not to consume less in games. Beside this it´s not the CPU nor the GPU that consumes most, but the backlight LEDs in your screen. So even by undervolting and underclocking it will still drain a lot if playing games.
There is no and will not be a magical Kernel that is using witchcraft to reduce the consumption of the LEDs, exept someone compiles you a kernel which turns out the LEDs completely, if you can with a complete dark screen.

Im not expecting anything from ur kernel, im glad that u shared ur kernel taht could last longer than arco's stock kernel.
I was just giving up my comments about ur kernel that i have used for 2 months , Not complaining and whining lol.
I am sorry and thanks for sharing ur kernel , keep it up. :fingers-crossed:

[Kernel] [CM9 final] honeyx 7up 3.0.x kernel [Silky Smooth & Battery] 02.09.2013

ZOHAN makes your hair...emmm Kernel silky smooth .
Well, since it became popular to add something like " for better battery life" I´m renaming my Kernel into Silky Smooth now
There are 2 versions now. First one is the pure kernel and the secound one with Turbo Boost included. (Credits are going to delta-roh)
Orginal thread: http://forum.xda-developers.com/showthread.php?p=37905307
SGW discussion thread: http://forum.xda-developers.com/showthread.php?t=2400120
Created with stability and battery life in mind. Each modification was tested separately, so everytime I added a tweak or a new feature, I tested the new kernel for a couple of days before adding the next one.
So what it has included:
- UV and OC options
- lowered WiFi voltage
- lowered LCD voltage
- slightly lowered standby / deepsleep voltage
- Battery life eXtender
- Fixed 100% battery notification after charger unplug
- 378MB RAM
- ROW scheduler as default scheduler
- Lulzactive Governor as default governor
- tweaked Lulzactive for battery life and smoothness
- added new frequency - 518MHz
- added new frequency - 633MHz
- added new frequency - 902MHz
- Screen Off frequency set to 518 MHz max. in Lulcactive Governor
- Dynamic Read-Ahead
- Dynamic Dirty Page Writeback
- CK3 tweaks (Credits to Con Kolivas) - adapted by Christopher, hurtsky and me
- LowMemoryKiller management of not killable processes - credits to christopher
- with and without Turbo Boost Mod
- no other compilation tweaks just to make the list longer
I didn´t test this kernel for how long it can last in StandBy / DeepSleep max., just for stability, how well the tweaks are working and how well the consumption is dropping in DeepSleep, but since the results are very similar to the ones by using 2.6 kernel, they also should be quite similar in this kernel. However with the new added 518MHz it will consume less in Screen Off Mode if the phone is active. So for example while making calls.
The max. Screen Off frequency is the maximum frequency your device can clock to while the screen is turned off. It´s a kind of limitation to lower the consumption.
other suggestions:
- enable KSM
- enable 16bit transparency
- disable CPU rendering
- greenify your apps
If you follow these suggestions, your ROM should run absolutely smooth without the need for other tweaks.
To use Battery Life eXtender:
Use RootExplorer and go to: '/sys/class/misc/batterylifeextender'. Change the value in 'charging_limit' for example to 90 (default 100). This will set a limit for the capacity to which the battery will be charged. So in this example the battery will be charged to 90%.
----------------------------------------------------
After flashing the kernel whipe your cache and dalvik cache and fix permissions.

Just in case you are getting random reboots with this kernel this is because your device doesn´t like the lowered voltages for DeepSleep /Standby. In this case use the kernel below insteed. It´s the same kernel but just without this tweak.

This is really heavy usage, so I´m not sure it will make a lot of difference even if you are undervolting. Most of time your screen is on and so the phone kept awake but it´s the backlight that is draining most.
It´s just there is no tweak for the backlight LEDs to make them consume less exept reducing the brightness, so may I ask if you feel any difference even under such a heavy usage?
I doubt that as the kernel is tweaked for Deepsleep / Standby but will of course consume as much as other kernels under full load.

Ok., let me say that I have use another kernel before with same time testing (about 3 hours and 30 minutes) and my battery drain so fast.
Honestly this kernel is good for battery saver because I have problem with my battery health..

this kernel compatible with cm9 rc2 or rc 3?
or use the EOL version one ?

It´s kernel 3.0.x so more likely for the EOL and as the title says it´s for CM9 final.

how much memory on this kernel?

GPS not working well or totally not working on this kernel.. please fix. TQ

For me it´s working well and I didn´t do any changes to it, so everything is like in the stock 3.0.82 kernel regarding this. It´s just you have to wait up to 15 minutes after activating GPS the first time after changing kernels to get a GPS fix.
I of course tested GPS before launching this kernel. It took me a while to get the first GPS fix but after this it´s now fixing immediately. However If you are using Greenify and are hybernating your Google Services, this could be the reason for not being able to get a fix.
Btw, this has been already discussed in the CM9 bug report thread. There are also some solutions to get it working.
http://forum.xda-developers.com/showthread.php?t=1598056&highlight=gps&page=299
But I also suggest to not to hybernate Google Services in Greenify as some apps require it to get a GPS fix. Once the Google Services got greenyfied those apps can´t get a GPS fix, even if you restart Google Services. So in this case remove Google Services from the list in Greenify and restart your device.

Personally I´m using these:
Code:
Freq. mV
245760 775
368640 825
518400 900
768000 950
806400 975
1024000 1025
1113600 1050
1209600 1075
1305600 1100
1401600 1125
1516800 1175
1612800 1225
1708800 1275
1804800 1325
It will also run stable for me by reducing each by -25mV. Just added 25mV to each for more stability.

Thanks for the great kernel, I personally haven't noticed much of a difference on standby with wifi on, but there is quite a difference when you're using the device, thanks again! :good:

Thanks for the feedback. Well about WiFi this is another story. While testing the consumption with WiFi on I honestly couldn´t see any difference between running WiFi at stock voltage or by undervolting it the way all the kernel modders are doing it.
It looked to me like this tweak isn´t lowering the consumption like it expected to be. Therefore I applied some more tweaks you can´t find in the Commits to lower the consumption while WiFi is enabled. The difference is not huge, but now it indeed consumes a little bit less. Beside this my tweak is a dynamic one and depending on the signal strenght.

this kernel is really impress me,.fast and smooth and really better battery life especially the 3.0.x kernel.
i dunno if this is just me but i have to report this,.
sometimes my phone just turn off by itself when i'm using it, both 7up kernel are the same.
is there anyways to fix this?

Hm well I´m not sure. Would need to know your exact setup to better estimate this. Did you install both roms the prstine way? Are you using any other tweaks, mods, themes or scripts?
I´m using Arcos stock CM9. There I´m using Apex launcher and the only mods I did is disabling CPU rendering and replacing the SMS/MMS app with the modded one. Additionally I replaced the Clock App with one that offers a digital Clock widget and swapped the SDCards, but that´s all about it.
It´s of course possible the tweaks in the kernel are somehow interacting with other tweaks, mods, themes or scripts. That´s why i cherrypicked all the tweaks I added into this kernel and skipped the ones that were causing troubles when combined together.

pristined as always,.
no mods, no themes, no tweaks and no scripts
only cm9 stock + 7up.
hmm..on 3.0.x got 2x turn off by itself. 1. while using Path, 2. while using Line..
i dont remember when my phone turned off when using 2.6..

Ok. I just forgot to ask if you are undervolting or orverclocking your device. However I will build you a test kernel without the slightly lowered voltages for Deepsleep and Standby because this is what comes into my mind what could cause you the random reboots. Kernel 2.6 has less tweaks than other kernels are having exept this one. In 3.0.82 kernel I tweaked them even a bit more. So maybe your device doesn´t like this.
I will PM you this test Kernel when I´m done, so hopefully we can narrow down this issue you are hiving.

Grand rebooting frequently

My Grand is rebooting frequently after installing carbon rom and nebula kernel
When I run any game, It starts to reboot. This happens even , when the screen is off.
That's why I reverted back to cm11

It's not because of ROM man.... It's kernel who giving random reboots.. U really should read at least few pages of it before flashing brother ... It's under development... Hope we get a stable kernel (nebula kernel ) soon.....
Till then.. Just use pre included one in ROM
Hope i helped

Nebula kernel is really unstable, I suggest you not flash it if you're planning to use it as a daily driver. Carbon/CM11 default kernel is already snappy, but if you want more governor/IO scheduler/overclocking more than 1.3 GHz then try k2wl's evolution kernel.
It still doesn't have KSM (kernel samepage merging) which is supposed to lower the RAM usage, but I think all AOSP-based ROMs are already very low on RAM usage.

Well holidays are already over, so I guess he's now busy with work/school/college. Devs are just regular guys...
The KSM feature isn't that much of a different anyway... What I'm hoping to see in next version is more frequency steps... as of now it is 312-600-800-1200-more but it should be better if like this: 100-200-312-400-500-600-700-800-900-1000-1100-1200... Hahaha maybe I'm asking a bit too much.

Why would anyone want to drop as low as 100 Mhz if 312 is good and battery saving??

Yes I think it will... because there are some apps that sync in the background (such as Google apps) even when the device is asleep. With the current frequency steps it is either Deep Sleep (no CPU activity at all) or 312 MHz... and I think 312 MHz is still too high for only background app syncing while asleep... just my 2 cents. :silly:
But I imagine people who use conservative governor will have a hard time using 100 MHz as the minimum frequency... because the governor scales the freq so slow, the phone will lag a lot longer when waking up :silly:
