Interesting. Would it be possible to allocate more ram to application use without compromising performance elsewhere and/or core features? For example could we sacrifice video recording and reclaim some ram?

That's a bit of misunderstanding from what I have gathered. Supercharger author DOES have an unfortunate teenager style of presentation but the substance seems to be rather well thought out. If you can look beyond the "wroom wroom" stuff. Not many things are "bulletproofed", rather the system is pretty dynamic down to how the memory parameters are defined. The current task gets priority and so do "recent apps", which get no boost at all in stock. You can also tune the process more towards multitasking or single app performance.

Main complaint is that with the odex stock ics the process is fairly cumbersome. I guess I could put up my supercharged stock ics + your kernel in dropbox in ready to flash package.. Can flashtool actually read phone firmware to a ftf file?
[Sony Ericsson Xperia Neo, Pro] 1stichiban:
great idea!

That would be highly appreciated!! Thanks in advance!
[Sony Ericsson Xperia Neo, Pro] Riyal:
Go ahead pack it up and upload :D

And regarding the salvaging of RAM I am afraid it's somewhat possible but unstable. DoomLord on the Doomkernel already tried salvaging at least 2mb of RAM from the camera and it became almost unusable already. So even if I managed to salvage some memory on those dedicated stuffs it probably won't be much. Anyways I implemented Compcache on the kernel which compresses memory data. That way we would have more extra RAM on the device than normal usage. The Ultima ICS already has Compcache support but I haven't uploaded the neccessary module for it to work yet.

Info regarding compcache:

http://code.google.com/p/compcache/

I have integrated v5 of compcache to Ultima Kernel just FYI.
[Sony Ericsson Xperia Neo, Pro] hazzik:
riyal please answer this. :(
[Sony Ericsson Xperia Neo, Pro] Barleyman:
How can I dump the phone firmware?

The instructions I have seen for taking a copy of the "phone" firmware were actually for reflashing the firmware from sony and copying the temp files..

I don't think my setup should be copied before it's a "little" bit more stable, though.
[Sony Ericsson Xperia Neo, Pro] Barleyman:
About compcache.. We don't have multicore numbercrunching CPU, I wonder how much lag we get from the compression. Is it possible to switch it off to see how much effect it has? Sysctl?
[Sony Ericsson Xperia Neo, Pro] RiCi12:
The biggest problem on compressing virtual memory of process is about uncompress it: you would spent time on this task. 512 mb of ram i think are enough now, we must focus on "take off somethins for kernel and stock rom". It's a bit difficult, i know, but it's the only way (that does not reduce overall performance) to gain some mb of ram!

IMHO!

I think riyal has made a great job! ;)

Boot-1.1.IMG seems to break GPS?
[Sony Ericsson Xperia Neo, Pro] Riyal:
Hi! Sorry I am not familiar with using titanium backup so can't really assist you with this one. However have you tried fixing the su binary permissions? Or probably try replacing it with some other su binaries.

Could anyone confirm this? As far as I know kernel doesn't have anything to do with GPS. The driver is located in the ROM itself so I don't think the kernel have anything to do with it. Anyways what do you mean by "break"? Does it totally not working? Or does it not lock or something else?
[Sony Ericsson Xperia Neo, Pro] 1stichiban:
Porting to PRO

Hi, i saw your post regarding porting of custom roms between xperia 2011 devices.

Sounds quite interesting, may be i'll try to give it a shot based on your "hints". Although of course if a CWM flashable zip is available it would make things pretty sweet :)

Thanks for sharing :cool:
[Sony Ericsson Xperia Neo, Pro] Barleyman:
Not lock and totally not working sound pretty much the same :cool:

Widget switches to "on" but no notification satellite icon and no lock. Does it work for you? I was driving to work with 2.3 test kernel running and it worked. I flashed 1.1 and on my way back no lock.

I guess this could be side effect of supercharger but does anyone have working GPS?
[Sony Ericsson Xperia Neo, Pro] Zolox7:
Oh great thanks
[Sony Ericsson Xperia Neo, Pro] Barleyman:
It seems compcache is not actually running, is it?
[Sony Ericsson Xperia Neo, Pro] hazzik:
Video lags every minute same as music anyone experience this?
[Sony Ericsson Xperia Neo, Pro] Riyal:
@barleyman

Cant confirm that since we have a very weak gps signal here. But try testing it on a clean rom. I tried testing gps and got 3 sattelites locked.

@hazzik

Not experiencing that on my device. In fact the only issue im having with ics is opening a flash video on default browser. But other than that nothing.
[Sony Ericsson Xperia Neo, Pro] Snoe II:
can the ics kernel work with cm9 ?

thanks ..

:)
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
It has been said a lot of times.

CM ROM works only with CM Kernel.
[Sony Ericsson Xperia Neo, Pro] Snoe II:

btw , thanks for the response ..

[Sony Ericsson Xperia Neo, Pro] hazzik:
Sorry noob question but what is this?
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
It's called features and/or changelog, and you don't have to repost it all again. It makes people waste bandwidth.

It will mark changes or features on the Kernel/ROM.
[Sony Ericsson Xperia Neo, Pro] hazzik:
Ooops sorry my bad. How do i install it? Thru cwm update from zip?
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
Read the instructions on the first post.
[Sony Ericsson Xperia Neo, Pro] hazzik:
Isnt that for wifi module only?
[Sony Ericsson Xperia Neo, Pro] 1stichiban:
i tried the link for Ultima ICS but it seems to be broken.

[Sony Ericsson Xperia Neo, Pro] Riyal:
Sorry forgot to update the 1st post :D

The latest one is on the quote

Update: Also new version is coming. Has another optimization added so it should be a little bit faster than the current.
[Sony Ericsson Xperia Neo, Pro] hazzik:
theres no rom for ultima ICS?
[Sony Ericsson Xperia Neo, Pro] Riyal:
Not yet. I need to have at least a decent/stable kernel before making a ROM.
[Sony Ericsson Xperia Neo, Pro] Barleyman:
Riyal,

You've been avoiding my questions re:compcache ;)

I DID go to the github page and rtfm. I can't find any of the processes or tools they mention. It's not compiled as a kernel module either.. So.. How to load/unload/change parameters of compcache?
[Sony Ericsson Xperia Neo, Pro] Riyal:
I didn't say I included the compcache on this kernel version I just said I compiled it as module and am currently trying it. I didn't add it here as it's not yet stable enough. Doomlord's kernel has compcache support integrated but I want to make one as a module so we could avail some other options like adding multiple devices rather than just zram0. Anyways I fail doing that at the moment :D
[Sony Ericsson Xperia Neo, Pro] hazzik:
I guess ill wait for it ultima gb seems unstable to me.
[Sony Ericsson Xperia Neo, Pro] mrezat:
I have problem with archive rar file...

i put it in my sd card and when i try to install it from cwm it stopped and make error...
[Sony Ericsson Xperia Neo, Pro] Riyal:
Download it again. You probably had a corrupt download
[Sony Ericsson Xperia Neo, Pro] mrezat:
thank riyal...

when u add overclock ability to ics kernel?
[Sony Ericsson Xperia Neo, Pro] hazzik:
Noob question can i use ultima ics kernel to ultima gb rom?
[Sony Ericsson Xperia Neo, Pro] Dexxmor:
It has overclock support, you can up to 2.0GHZ

No, only for stock ICS or ICS MIUI
[Sony Ericsson Xperia Neo, Pro] hazzik:
i flashed ultima ics kernel to ultima gb and it seems working and stable to me.

ill just test the battery life.
[Sony Ericsson Xperia Neo, Pro] naveen88:
@Riyal

Good work dude, thanks. :)

I am using your ics kernel v1.1 with stock ics 4.0.4 mk16a rom. It has been buttery smooth till now. I have enabled smoothass governor alongwith deadline I/O with overclock to 1.5ghz. Will let you know soon how the battery behaves. :)

Edit:- Just to confirm that GPS is working without any problems for me as I have seen other users reporting that GPS doesn't work.

PFB the steps which I used to flash your kernel:-

1) Flash Ultima ICS v1.1 via fastboot mode

2) Enter recovery and do a full wipe+dalvikcache wipe+wipe battery stats

3) Switch off phone and open flashtool in pc

4) Select official SE 4.0.4 ics firmware, exclude kernel and select no final verification.

5) Connect phone in pc in flashmode

6) Flash the firmware

7) Enter into recovery mode and flash wifi modules

8) Power on the phone and done!!!
[Sony Ericsson Xperia Neo, Pro] hazzik:
how did u overclock?
[Sony Ericsson Xperia Neo, Pro] naveen88:
I used No-frills cpu control to overclock. You can find it in play store.
[Sony Ericsson Xperia Neo, Pro] krish225:
Battery Report??

How is the Battery status? please please let me know in Detailed way
[Sony Ericsson Xperia Neo, Pro] sj8023ld:
hey,I llike your kernel very much , could you share your kernel source with us ?
[Sony Ericsson Xperia Neo, Pro] Barleyman:
Wrt gps, I'm pretty sure it would've worked ok if I had rerun supercharger again as it does some manipulations on android guts. Deodex, deassemble, modify, assemble and odex again.. This really begs for diff-based approach.

About performance. You have stock ics rom with no tweaks? What kind of sdcard you do have? I had really bad performance here. I have aggravated it by batch transferring apps to sdram with titanium backup which does not respect sdcard limitations. Hence for example chrome had awful lag.

My card is 16GB class 10. Very fast for large file transfers and utterly sucks for small files. I wonder if reformatting it with ext2fs would help..

I installed the latest CM9 FW and there's really dramatic difference in speed. Everything is now snappy as it should be! I may revert back to stock + ultimate kernel to see if returning some key apps to internal memory does help significantly.
[Sony Ericsson Xperia Neo, Pro] naveen88:
Yup I haven't done any tweaks and I also use 16gb lass 10 transcend sdcard with 4gb of free space left. I had also used chrome beta and didnt find any sort of lag. have you overloaded your sdcard?

Overall I am satisfied with this kernel. Will be trying out other governors and let you all know how the phone fares :) PFB battery usage details below:-

After 17h 19m of medium usage with about 45 mins of browsing via wifi, bravia engine and gps on all the time, battery has come down to 10%. Below are the usage details:-

Screen = 43%(2h 23m)

Android system = 17%(4m 55s)

Voice calls = 10%(17m 26s)

Cell standby = 9%(17h 18m)

phone idle = 8%(14h 58m)

mediaserver = 8%(3m 59s)

where's my water game = 6%(31m 45s)

Screen brightness was set to around 45%. You can find cpu overclock details in my signature.
[Sony Ericsson Xperia Neo, Pro] Barleyman:
Chrome started working ok after I moved it back to phone. There is unreasonable lag getting sdcard mounted initially and doing anything on sdcard in general. I made sure all resident-type apps are in internal memory and it helped with big lag spikes.

However, CM9 does not have the sdcard issue and its much faster for me with same clocks (1.6GHz) and governors (ondemand, deadline). I don't think its kernel related, there seems to be a problem with lag in stock rom in general. I had it with no tweaks too.

Waiting for that cm-compatible ultimate kernel :D
[Sony Ericsson Xperia Neo, Pro] nandakalyan:
Same here....kernel runs fine for CM9....temple run almost crashed twice since I usually put it on the SD card but otherwise everything looked great. Off and on issues with network connectivity but not sure if its because of the kernel...Ultima Ultima...Go Riyal!!! :good:

[Sony Ericsson Xperia Neo, Pro] 1stichiban:
hi,

did you use the ff:

fastboot flash boot boot-1.1.img

if yes, boot image should still be the Ultima ICS kernel :) even after a reboot.

Can you integrate cm7.2 125 with Ultima ROM?

I found a few bugs to cm7.2:

- not loudly loudspeaker

- Fm radio and HDMI is not working

- save brightness less perfect

but I found several advantages:

- faster and lighter

- lots of free ram

if you could combine the two rom the above would be perfect ...

one more, can you change the splash screen with another image?

thanks
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
Ultima ROM and CM are 2 different ROMs.

They don't work together.
[Sony Ericsson Xperia Neo, Pro] Riyal:
Update

New kernel release later :)

Also regarding Ultima ROM ICS. I still don't find it neccessary since mostly all of the mods for ICS is applicable to the current stock ROM. I think this negates my past intention on making Ultima GB since the mods on the GB ROM isn't quite very compatible with Xperia Pro.

In fact with Xperia Pro stock ROM you could flash thiniliac's Xperia S transformation pack and you almost got a fully custom ROM.

Anyways after the kernel matters I will resume my work with the patcher. Plus I am watching closely with CM9.0 progress if I find it stable and feature pack enough then perhaps that would make me consider making an Ultima ICS kernel for CM and probably make Ultima ICS ROM for CM.

So as of right now I'm all eyes on 2 projects. The FreeXperia ROM and the Paranoid ROM as those two seems to grab my attention the most.
[Sony Ericsson Xperia Neo, Pro] 1stichiban:
Hi thanks for your update.

B-)

Looking forward to testing the next release.

Thanks for all your hardwork.
[Sony Ericsson Xperia Neo, Pro] zephyr83:
I hope to see soon a rom with linaro "mod" :D
[Sony Ericsson Xperia Neo, Pro] mrezat:
Yes... With flashboot
[Sony Ericsson Xperia Neo, Pro] Riyal:
I got a decent port of this last year ago. But it's not on android but on my n900 device which runs maemo OS. Since multibooting on that device is as easy just like on a desktop PC. I am just 4 months old with android so I am not yet that pro with this kind of stuffs so my answer would be... "I'll try" :D

Also I still have ideas on implementation like porting uboot for our Xperia phones. Hopefully :D
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
You'd need to base it off the CM Kernel instead of stock, and we'd need more someone who provides a Stock Rom more than a modification of CM.

Also, Paranoid Android is already being ported.
[Sony Ericsson Xperia Neo, Pro] Riyal:
I won't base it on either stock or CM kernel it has it's own arm kernel to begin with. Perhaps I might start as a chroot environment. The drivers are the real pain on these kind of development.

Also I am just eyeing paranoid ROM. Which means I might make the same concept of it but not port it. :)

It was made for another android device porting it would just break some of it's features it's better making a whole new one instead which is purposely made for our device.
[Sony Ericsson Xperia Neo, Pro] RamEsRock:
So a new ROM based on other qualities huh. Keep up the work.

(You don't need to talk to me about "arm kernel" or "chroot environment"... I don't know what those mean, lol. I just know how to flash kernel/ROM xD).
[Sony Ericsson Xperia Neo, Pro] N2A:
I've flashed your kernel this morning onto the MIUI ROM that was released here - http://xdaforums.com/showthread.php?t=1699647 - which was working fine. All seems to boot okay and function, except now it no longer goes through the "Preparing SD card..." process, and showing my apps off my MicroSD. I noted in some earlier posts that you said you'd disabled the script for sd-ext, but I'm guessing that's for an actual ext3/4 partition rather than just the standard ICS external app installs to a FAT32 card.

If I missed something obvious, please do tell me (I hate asking unnecessary questions, and I'm pretty sure I've trawled the thread where relevant and checked the MIUI thread too), and I know it doesn't help that it's a non-stock ROM to start with, but could you give me any pointers as to what I'm missing? Some sort of mount command somewhere perhaps?

Oops, never mind, turned out they'd just hidden on other screens and reappeared elsewhere. Not sure how that one had happened! Keep up the good work ;-)
[Sony Ericsson Xperia Neo, Pro] nosedive:
got JJHybrid working here with riyal's kernel.

are you interested? i'm not sure if it's bugfree but hey, two pair of eyes are better than one :)

looking foward to your new kernel release.. i wonder if automatic backlight is kernel or ROM?

Paranoid Android is one of the most interesting projects here.. i hope for a real port for xperia pro.. unfortunatly these are based on CM so i guess there might be changes needed for your kernel.. the most bad stuff about fxp kernel is battery life.. i'm trying fxp builds since fxp122 and battery life is about 60% less than with sony ICS - this is far from well working.. and there are other bugs that need to be ironed out so i hope it will get better otherwise they shouldn't call it RC's :(

Kernel Update(ICS)

V1.4

Lot's of optimizations and fixes on pointers

Network tweaks on kernel side

Added some more implementationf of Xperia Ultima kernel gingerbread

Stripped debugging feature on WIFI modules. (Should regain alot of space on /system partition)

Altered OOM settings to regain more RAM.

Compiled with additional flags for better implementation and performance of processor & GPU driver

Added full support for loop device. (Now you can mount images on the phone) sample project here - http://xdaforums.com/showthread.php?t=1585009

Increased VMMaxReadAhead

Added SHA256 encryption support for ICS

Workaround & created a new implementation of config_netfilter _xt_match_owner because old one conflicts with qtaguid. Kernel should support Apps like Droidwall, Orbot and any firewall programs fully now.

[Sony Ericsson Xperia Neo, Pro] Riyal:
I will be working on CM ROMs if all the features are already working. I am willing to fix those bugs specially the one in battery life.

And true ROMs like paranoid depends on CM kernel so before I work out on ROMs like that you all should wait first for me to make a CM kernel first. :)

The only leaked jellybean ROM for now was just a system image from SDK. Although we could have it I don't think anyone would be interested in it. ROMs from SDK are just super stripped versions to the point that no one would appreciate it that much yet. I think it should just be composed of a web browser, phone, messaging, and some basic android stuffs and bloatwares :D
[Sony Ericsson Xperia Neo, Pro] naveen88:
I had already installed ICS kernel v1.1. Should i just flash v1.4 again or flash it and then do full wipe?
[Sony Ericsson Xperia Neo, Pro] Riyal:
Just flash it. Wiping/factory reset is only for ROMs as you need to rebuild dalvik cache for some conflicting apps and stuffs.
[Sony Ericsson Xperia Neo, Pro] MrMmmkay:
Could it be that there is an battery drain in this Kernel (1.4)?

Phone was fully loaded over night, after 6 hours the battery is down to 72%, it was just in my pocket, not one minute in use.

Wifi is set to deactivate in standby, bluetooth is on, but not connectet, Autosync is on. OC to 1,5ghz, but locked to max 368mhz with phone off, smartass2, deadline, undervoltet to 750mV on the lower frequenzies.

On my Xperia Play the drain is much smaller with same settings :(.
[Sony Ericsson Xperia Neo, Pro] cccs1:
wifi didn`t turn off in standby, that`s the reason for your battery consument

so if they fix this, battery will be ok
[Sony Ericsson Xperia Neo, Pro] MrMmmkay:
Ok, that would explain the drain. So i hope that this will get fixed soon :)
[Sony Ericsson Xperia Neo, Pro] Riyal:
WIFI management is not related to kernel the ROM itself handles it. So can't do anything about it. What WIFI modules does is only let phone have control on using the WIFI hardware that's just it.
[Sony Ericsson Xperia Neo, Pro] MrMmmkay:
Thats bad :(. So we can only wait till sony brings an official update? Till then i just deactivate Wifi manualy, or i have a look at greenpower, i think that app can hadle that too.
[Sony Ericsson Xperia Neo, Pro] Riyal:
By the way just to be sure could you try reflashing back to stock and monitor WIFI? I just wanna be 100% sure of what I said. If it's not happening on stock ROM I'll try to look into the problem.

[Sony Ericsson Xperia Neo, Pro] Riyal:
That should not be. I am currently using the latest kernel I uploaded here and with an overnight stats of 8% in 10hours. So probably the issue is with the ROM now. Or anybody here experiencing battery drain?

Yup, I am also experiencing the same issue. Battery drain in v1.1 was more less compared to this version.

Btw....any comments on the jelly bean link for galaxy nexus i posted earlier? Is it possible to port it to xperia pro?
[Sony Ericsson Xperia Neo, Pro] MrMmmkay:
I am using the stock rom without any tweaks except your kernel and wifi modules.

The Xperia Mini Pro of my girlfriend runs with the same settings as my pro and has ~88% after 6 hours, also costum kernel and ics stock without tweaks. Mini pro has smaller screen, but afaik also smaller battery ;).
[Sony Ericsson Xperia Neo, Pro] Dexxmor:
Possible is all, but the driver's for the pro must be portet to JB, and this is really hard.
