Hi,

first, I know that RAM is separated to several parts, one for Android OS + apps and other for low level hardware, RIL, GPU, hardware acceleration, camera etc. No need for that kind of answers here, thank you :)

So, I know that on some kernels (on other devices) there is way to map more RAM to user by reducing GPU RAM, freeing some memory banks from camera etc.

In that case it is possible to have more available RAM for user and applications in trade for possible HD video stutter, worse 3D performanse and/or no HD video recording. Also, it doesn't mean that only GPU RAM banks can be decreased, maybe something other can be modified to free more RAM.

For example, HTC Sensation ROM has that kernel with more RAM but no FullHD recording.

Similar thing is with Optimus 2x ROM that gives 64MB of RAM more than stock values.

Xperia Ray (with ICS kernel in this case) also has 15 MB of RAM more than usual. Not a big improvement but still it is possible.

There are numberous cases with such modifications and tweaks (from Galaxy W, Galaxy S Plus, to Motorola Atrix, Galaxy S and so on...)

Our Xperias have 1GB of RAM from which 685MB is available on JB ROMs (on [MENTION=834547]letama[/MENTION] 's 4.3 ROM is 622MB), where with 3.0 kernel some ROMs have 715MB of user available RAM.) From one older (ICS for Xperia 2011), but still relevant Xperia blog entry there is one quote that somewhat explains one bit of that:

Also relevant:

Additional info

Because on CM based ROMs there is no Bravia Engine, some specific Walkman album and/or video features and big chunk of users (like myself) don't need fastest 3D performance nor 1080p (which is still lagging, well until .96 source code arrives. Minding that, is it possible that in .200 builds wrong memory mapping led to FullHD stutter?) but additional RAM would be precious for multitasking and having more apps open at the same time.

Unfortunately I am out of luck regarding some tutorials or explanation how to set up kernel and tweak its memory map (because I lack of Android development knoledge) but I hope someone out there like letama, RaymanFX, DoomLord etc. can help. It doesn't meant that they must do it but maybe give us "noobs" some directions how can we start and try to do it ourselves.

Sorry for long post, I didn't want it to became "another RAM thread" because it isn't. The more explanation provided the less confusion is present :) Thank you for reading it until end :)

[Sony Xperia S, Acro S, Ion] funky0308:
First of all - good topic :D

It's obvious there is a way to increase available RAM if you look OS version on one device with same hardware but just different OS.

In Gingerbread, ICS and then in JB.

If you just compare 211 and 96 firmware there's big change.

HD video (1080p) recording is great..

So I guess it's RAM mapping which should fix in custom ROM's

But for me it's not so important how many RAM I have free, I want my RAM to be occupied and fully working to get best performance.

But in some ROMs we could see 70MB of RAM free and terrible performances.

To close this - I think Sony did a great job with 96 firmware and that's good.

Only question stays for custom ROMs

It's question for developers who really built ROMs from the beginning and do everything alone.

We have few great guys here but I doubt they will join this conversation ;)

[Sony Xperia S, Acro S, Ion] letama:
Well, I don't have all the answers for this, but let me give you some hints:

In recent kernels (JB), memory allocation is handled by ion. ion is managing pools that are dedicated to specific tasks. Memory dedicated to each pool is defined by kernel, in board file for our XS (arch/arm/mach-msm/board-semc_fuji.c)

Here is what I have for mine:

#define MSM_ION_HOLE_SIZE SZ_128K /* (128KB) */

#define MSM_MM_FW_SIZE (0x200000 - MSM_ION_HOLE_SIZE) /*(2MB-128KB)*/

#define MSM_ION_MM_SIZE 0x3E00000 /* (62MB) */

#define MSM_ION_MFC_SIZE SZ_8K

#define MSM_ION_SF_SIZE 0x9000000 /* 112MB -> 144MB */

#define MSM_ION_CAMERA_SIZE 0x7000000 /* 80MB -> 112MB */

#define MSM_ION_WB_SIZE 0xC00000 /* 12MB */

#define MSM_ION_QSECOM_SIZE 0x300000 /* (3MB) */

...

Which are sony JB values except for SF and CAMERA that I had to increase for 3.4 (new drivers, consuming a bit more).

This is where you can play to try to get more free ram, but it will be difficult without impairing a function.

Regarding the 1080p issue, this has nothing to do with ram. With my same kernel and same memory allocation, issue is fixed with new sony camera blobs.
[Sony Xperia S, Acro S, Ion] switzerland92:
Thank you for your answer, it really helped me a lot :)

Is there any article or explanation for e.g. that is MSM_ION_SF_SIZE etc.? I realized for some stuff from context but most of that is unknown.

hi guys! i'm benz and i'm from the philippines. i just recently bought a mint xda2..i was wondering if you could help me with some of the basics. :D i don't know where to start! (this forum is so full of info!) since i'm beginning to experiment with upgrades in OSes, can you guys fill out something for me? thanks!

1. i noticed there is a WM2003SE OS and a WM2005 OS for the xda2. i was wondering what are the differences of this OSes?

2. it's possible for WM2005 to go back to WM2003SE (or even the default xda2 O2)?

3. when it comes to stability, is the XdA2JoJo.v3.2zS version the best for my xda2?

4. I don't know about you guys, but my GSM signal for SUN seems to be reaaaaally lagged everytime. is this affected by the rom? (i'm using the latest O2 upgrade).

finally an OT question:

when converting a DivX movie to play for my xda2, how big will the file usually be?
[MDA II, XDA II, 2060 ROM Development] Robson:
some inputs to your questions...

1. i noticed there is a WM2003SE OS and a WM2005 OS for the xda2. i was wondering what are the differences of this OSes?

ans: one big difference from the original os to the 2003se is the ability to switch from portrait to landscape mode easily and without kinks. before this rom came out a bunch of chaps (including me) tried using software like jslandscape or nyditot for landscape mode. for the 2005, it takes the 2003se even further by adding a whole lot of enhancements. xda2jojo and buzz and toenailed did some very amazing work in bringing that rom to the xda2. and chances are they're still working on making it even better.

2. it's possible for WM2005 to go back to WM2003SE (or even the default xda2 O2)?

ans: downgrading from 2005 to 2003se is possible and has been done by myself and other people as well. for the original os, as long as you have a copy of that rom then it should be possible...though most chaps i know either stayed with se or 2005. btw, 2005 rocks!

finally an OT question:

when converting a DivX movie to play for my xda2, how big will the file usually be?

ans: i use divx; when i converted my dvd of spiderman2 for ppc use the resulting file was around 130mB. i think it depends on the movie length...to be safe you would probably need a 256mB card at the very least for one movie/dvd

cheers
[MDA II, XDA II, 2060 ROM Development] benzxi:
thanks for your inputs! other differences in WM2003 from 2005?

how "buggy" is 2005 for the xda2 anyway?

[Asus Transformer TF700] comomolo:
Hello,

My tablet is unlocked and I am a CROMI Roms user. I have flashed my tablet many other times as the CROMI version will go up without any problems.

I allways select the stock kernel. However, in the last version I installed (CROMI 5.0 Beta1), I selected the Hundsbuah OC kernel (3.2). During some days, I performed some tests changing the governor, frequencies and volts. At the final, I did not like this kernel as the tablet was very hot all time (even at low frecuencies), so I decided to remove this version, flashing the next version available: CROMI 5.0 Beta3

This time, I selected the stock kernel in the Aroma installer. After the installing, I rebooted the tablet. However the system stops in the boot animation and start again from the beginning (loop). After several reboots, the tablet was showing the initial screen with the logo of ASUS (the one where you can read that the device is unlocked) and re-boot again. I do not see any more the animation screen.

I am able to enter in the recovery (TWRP 2.5.5) so I have tried to restore the backup (in fact several backups with different versions that I was stored in the micro-sd) and all of them fails while the restauration of the data partition. I mean, the restore set the 3 partitions (system, data and boot) to the original status. The system partition was restoring ok, but when arrived to the data partition I received an error message and restore process failed. All times happend the same with all backup files that i tried to restore.

I also tried to flash other new ROMS and versions without successfull. It is allways showing the same boot loop after flashing.

Could someone help me or give me any idea of what can i do before I get the tablet to the technicall service?

Thank you so much in advance.
[Asus Transformer TF700] sbdags:
It's an easy fix but you will lose your data. Your /data partition has become corrupted.

To fix it go into TWRP and go to wipe. Choose the Format Data button.

Then you can reflash CROMi-X but don't choose Hunds kernel I am releasing a safer version later today.

Obviously make sure you have a ROM.zip on the external SD card before you do this.

Try stock deodexed Rom.

But whatever u do,do it with battery abv 50% or you will brick your device.. It is not a hardware or battery issue. So even if u buy a new battery, u can use it till it ends and then buy another one.there's no point in it. Use an external charger to charge the battery, or u can use an adaptor and boost the battery( if u know what u r doin).

Nice Tutorial how ever you can Ship S-On a device from Ship S-Off with a simple adb command.

The command to use is just simply

echo -e 'at@simlock=7,1\r' > /dev/smd0

this command worked on my HTC wildfire when i first tried it after i used a XTC Clip to S-Off that device and i also used the same command on the Desire HD and it also worked on that.

lee boycott have mentioned about this method on the forums, http://xdaforums.com/showthread.php?t=2185167

I mentioned it on another forum as well, http://goo.gl/mxklnz (Mods if this link is not allowed let me know)

So its a case of simply typing

adb shell

su

echo -e 'at@simlock=7,1\r' > /dev/smd0

sync

Then reboot and there you have it you have S-On

But this method will keep the Super CID unless you change the CID before using above command.

Try This

I have the same problem with my g-sensor so I tried this way and it always work with my HOX , as long as you have a car charger

-the idea is to overheat your HOX , keeping at active all the time

-You need your battery to be around 50% not more than that , as you need to give it a chance to charge

-I open my data connection + map + navigation + screen on brightest available and on all the time + and connect it to car charger

the phone will heat up fast within 5 minutes

-once you feel your device is hot enough do a restart (fast boot way works for me )

-once your device is on back try to run your camera to see if your g-sensor is back

-and once its back dont turn your device off or restart it as the g-sensor will go back offline and that including flashing a new ROM

-I have use g-sensor debug from play store to check my g-sensor all the time , once you turn it on it will recognize it as Panasonic 3-axis Acceleration sensor with numbers running up and down , but if the g-sensor is off ill will show nothing
