[Sony Xperia S, Acro S, Ion] DooMLoRD:
there were some prominent changes in the .96 kernel sources so i suggest you use this on .96 firmware only!
[Sony Xperia S, Acro S, Ion] Felimenta97:
Hmm... I see... Well, I will try it to see how it goes. Make a backup just in case ;)
[Sony Xperia S, Acro S, Ion] DooMLoRD:
currently Xperia Z and the Xperia SP are my daily use phones so i am depending on you guys for reporting any issues on this kernel release!

please do keep giving feedback!

feature request are welcome!

dont ask for ETA though ;)

regards,

DooMLoRD
[Sony Xperia S, Acro S, Ion] Lunatiic:
Just waiting for Niaboc to release the new ExistenZ so I can test the kernel. I'll report anything I can find :D (but I hope it's as stable as v5 Haha)
[Sony Xperia S, Acro S, Ion] MclarensARC:
Kernel instalation okay, good jod dom! You are a legend!
[Sony Xperia S, Acro S, Ion] Felimenta97:
Just installed this over v5 running eXistenZ v2.

As DooM said, got problems with WiFi modules. Except for that, it seems to work fine...

Even on a phone that hasn't had a clean install for months, it is running perfectly. Huge performance with IntelliDemand governor, but still keeping the processor at low clock during no user interaction, and 2nd core is finally working perfectly.

This, coupled with eXistenZ Ultra that should come in the next few days, will make the Xperia S shine on all its glory again, so we call all throw it at everyone's faces haha

So, tl;dr: DooM, works perfect (WiFi isn't your fault).

Best kernel ever made to Xperia S EVAR!!

DooMKernel V6

....and we're back. :o

Installed DooMkernel v6 as an .elf as I'm to slack to install CWM recovery when the Kernel installs it for you anyway.

As [MENTION=2784807]DooMLoRD[/MENTION] states, the CPU clocking issue appears to be history. [Little happy dance moment]

WiFi working well on stock ROM with DooMKernel v6

I use SetCPU and have Kernel Tuner installed and they all mirror each others settings.

One thing I do note, in SetCPU the clocking frequencies are duplicated so we see the frequency listed twice 192,192,384,384....1728,1728

This is true for all listed frequencies and both min and max MHz

Doesn't appear to create a problem, it just makes setting frequencies in SetCPU...'cluttered' and 'cumbersome'

The following are two AnTuTu v4.0 benchmarks.

Stock 6.2.B.1.96 score 12732 [performance/noop] @ 1512MHz

DooMKernel v6 6.2.B.1.96 score 14153 [performance/noop] @ 1728MHz GPU 3D @ 320MHz
[Sony Xperia S, Acro S, Ion] Felimenta97:
Doom. Running it really good. It is flying, but for some reason I only got 5500 on AnTuTu. I know benchmarks doesn't say much, but... I've been getting that lately, It isn't applying the settings to the second core... It might be the CPU sleeper app I'm using... Unninstalling it to try again...

Seems second core only goes unitl 810 Mhz...

EDIT: After unnistalling it, second core now turns on, but it doesn't change frequencies based on the governor... The CPU control app built into eXistenZ ROM doesn't seems to be working...

EDIT 2: Seems like the app I'm using to monitor the actual frequency isn't working... Gonna have to find other.

EDIT 3: According to SetCPU, the CPU is jumping back and forth between 1728 Mhz and 192 Mhz quickly. Ondemand and scheduler cfq... Does't seem to increase as needed. At deadline seems better. I still need to avaliate that...
[Sony Xperia S, Acro S, Ion] alexander_sirakov:
Bravo DooMLoRd! I have a queston- why using SetCPU the frequencies are doubled? I mean there are TWO 192 MHz frequencies, TWO 384 and so on ...

"...[ how to install my kernel ] (via recovery)

download the kernel package update.zip

save the package update.zip to sdcard (of phone)

reboot phone and enter recovery

flash the kernel package update.zip

reboot phone and enjoy the kernel

download the kernel package update.zip

save it on c:\ and extract the kernel.elf from the package

save the kernel.elf to the folder containing fastboot binary

[Sony Xperia S, Acro S, Ion] BobbyManifesto:
I've got doubled frequencies aswell
[Sony Xperia S, Acro S, Ion] LLy_BosHi:
I also experienced that

All set cpu apps messed the cpu freq

I've been testing with no frills cpu, antutu cpu, and others

And yes, in no frills cpu settings the freq list is doubled

Hmm.. When I tested opensemc kernel or pac stock kernel the default max freq is come 1.672 on SL (follow the SL cpu stepping)

In this kernel is set 1.5 same as S default so I need to set manualy via some set cpu apps
[Sony Xperia S, Acro S, Ion] moe18:
Hi doom thanx for kernel

Im having issues with cpu frequency, the. Same as in the last post, freq are going at max and min fast, but almost al time is at max. here a screen.

Tried different cpu apps, all of them shows the same

[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
XPERIA LT26i DooMLoRD Kernel V1

My XPERIA LT26i is now going off like a frog in a sock. Brilliant. :D

I installed the DooMLoRD Kernel v1 on the 6.2.B.0.200 leaked JB version as I'm having problems loading the Sony released 6.2.B.0.200 ROM, but I notice with the new kernel (as documented), CWM is back to v6.0.2.7 from CWM v6.0.3.2, so maybe worth another attempt to get an official version loaded.

I too see the double CPU max frequency in SetCPU. Doesn't seem impact anything that I've noted at the moment.

With the Overclocked GPU it does run VERY hot gaming with HDMI to a big screen.

In the past I used RaymanFX Elite GPU overclock kernel.

There is a noticeable improvement with the GPU overclocked as seen in Epic Citadel benchmarks.

So, I'd like to see the GPU overclock option, but maybe like RaymanFX did and have GPU overclocked version of kernel and a non-GPU overclocked version. Unless it can be discretely turned off/on. Just a thought and only based on my limited experience and not wanting to offend.

Using SetCPU you can create a profile to change the max frequency and governor when temperatures gets to high to help manage temperature.

BUT WARNING, most aftermarket batteries disable any temperature monitoring and that includes Mugen Power batteries. Doh!!!

Probably not good form, but thought I'd include a Kernel v1 AnTuTu to give the punters an idea of how DooMLoRD is improving performance for us. Go you good thing.

Sorry to be so chipper, but now both my XPERIA S(LT26i) and my XPERIA X10i have the same boot logo. :laugh:

It's so cute, I like it.
[Sony Xperia S, Acro S, Ion] davidbar93:
Wow ,really nice score bro. My Best with DooM's kernel is 9021.
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
Looking at the same stats in SetCPU.

Over time I am seeing the 1728000 frequency decrease and the 192000 frequency increase using SetCPU.

I did a whole bunch of benchmarks using performance governor at 1.7GHz which explains my CPU frequency.

Just while writing this post the 192MHz frequency has increased by 4% and the 1.728GHz frequency decreased by 3% and my new max of 1.6GHz is now taking on the upper frequency load.

Using 1.6GHz as max set and now both 1.6GHz and 192MHz are the dominant frequency using ondemand governor.

I don't really worry at this stage as DooMLoRD will release Governors better suited to a dual-core CPU at a later release.

CPU Spy is noting an increase in the sleep state over time (33% and increasing) so I don't see an issue when we're only dealing with 'old' standard governors with additional governors coming soon. ;)

Just my thoughts.

[Update regarding CIFS]

I see we're going to disable CIFS or we have disabled CIFS.[??]

What is/was the thoughts behind disabling CIFS.

I have used it extensively (even though CifsManager is getting a bit problematic on ICS and beyond with permissions on the remote node)

Neutron Music player has builtin access for my NAS music library, as does BSPlayer Pro for videos and now also Root Explorer v3 so it's not the end of the world, but was going to look at the whole CIFS thing in conjunction with EDS AES-256 encryption app and remote NAS TrueCrypt files.

[Sony Xperia S, Acro S, Ion] ernie100ya:
Thank you for the hard work [MENTION=2784807]DooMLoRD[/MENTION] !

And in my understanding, to root it just flash this http://xdaforums.com/showpost.php?p=42005929&postcount=3

Is that right? :fingers-crossed: Since it doesn't contain root access in this kernel (I think)

The performance is really amazing, I got 9209 on Antutu without overlocking and cleaning my apps !:highfive::good:

[Sony Xperia S, Acro S, Ion] FenrirMX:
Yes.

Be patient, it will come.
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
That's what I did.

Before installing DoomKernel v1 I had root access.

I installed DooMKernel v1 from CWM recovery with the zip located on my /sdcard.

Checked and noted I didn't have root access anymore (SetCPU application told me I no longer had root access).

Rebooted into CWM recovery and install the zip file from /sdcard contain SuperSU and Busybox that you have refereed to...

After successful install, rebooted and I had root access again.
[Sony Xperia S, Acro S, Ion] Chris_Castro:
I know it will come. The thing is that I've seen a thread about stamina for ion, and it is said that a kernel tweak is necessary for full functionality for xs. Since Doom is working on the kernel, I thought I could ask. I think this is a major feature for our beloved device.

[MENTION=2784807]DooMLoRD[/MENTION] v6 seems to be good.. I am on stock .96 deodexed.. After flashing the kernel, on the first boot my phone didn't charge(not even on USB).. Reboot again and charging worked fine.. And no problems with Wifi or anything.. Getting good benchmark results with intellidemand governor.. Also i would suggest 30mhz and some more before 192mhz underclock and 1.7ghz is enough OC to let the phone stay safe.. Ofcourse, you will know if there is something wrong with too much underclocking like 30mhz.. And i found an issue, GPU OC worked only for 3D i.e 320, but 2D stays in 200 doesn't go to 266mhz.. Is it only me or anybody else?? :confused: If its the issue in the kernel, i guess u will fix it in v7.. Also suggest some more governors.. BTW Great work mate.. :)
[Sony Xperia S, Acro S, Ion] DooMLoRD:
Dynamic File Sync:

The dynamic sync control interface uses Android kernel's unique early
suspend / lat resume interface.

While screen is on, file sync is disabled
when screen is off, a file sync is called to flush all outstanding writes
and restore file sync operation as normal.

anyone else has similar issues?

2D: 200 MHz

3D: 266 MHz

overclocking can lead to artifacts

i will develop only for devices which i have: Xperia Z, SP, T, S [soon Xperia Z1]

kernel is patched to use .96 kernel sources so i cant guarantee that it will work on older firmwares...

no use of 30MHz bin.. will cause issue while waking up...

will now increase OC above 1.7GHz since the 2nd core is fixed..

2D is not yet overclocked.. i will add 2D O/C soon...

no use of having tons of CPU governors... just a few good ones are enough...

next up i will add some more I/O schedulers, etc...
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Yes mate.. I had forgotten about it.. When i had set min freq to 30mhz, phone's illuminating light only lit, but screen didn't wake up the 1st time, i had to press the power button again as if i were to lock the screen and again wake it.. And i guess performance governor has some problem.. Even my phone heats up with 5 mins in hand playing games like NFS MW or even Candy Crush Saga.. It wasn't there in Stock.. May be it has something to do with voltage in Performance governor.. U might wanna take a look at it again..!!

EDIT: If it helps, i have given Benchmark results of 3 different config.. 1st is Stock kernel's(CPU0-Ondemand,CPU1-Conservative), 2nd is DooMKernel(Same governors) and 3rd is DooMKernel(Performance for both CPU cores).. U can see the big difference..
[Sony Xperia S, Acro S, Ion] jfxperias:
Yes, the performance is not good for benchmark and hardware... I don't know why he exist...

[MENTION=2784807]DooMLoRD[/MENTION]

The big default is the frequency double and cpu0 in max and use process at 100% on Sio and Ondemande... Why???
[Sony Xperia S, Acro S, Ion] DooMLoRD:
thermal scaling... the CPUs are getting throttled down because of heating up... do the same test when the device is not heated up and then you will see results yourself...

performance is decent...

freq double showing is got to do more with the way the apps "see" the tables... not really a major issue...

u must ahve something running in background...
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Yes i waited for the phone to cool down and then tried it.. That's the maximum i could get.. Although Ondemand governor never lets the phone heat up.. Performance governor does let the phone heat because CPU cores keep running [MENTION=218088]Max[/MENTION] freq set most of the time.. :/
[Sony Xperia S, Acro S, Ion] DooMLoRD:
i got above 14k in Antutu while testing on performance governor...
[Sony Xperia S, Acro S, Ion] tOrNadO™:
I'll try once more after some time of Deep Sleep.. May need some time for the kernel to settle down.. Will report what happens next.. :p
[Sony Xperia S, Acro S, Ion] jfxperias:
Yes it's true...

=================================

No, my use process bloc at 100% when I put Sio... After reboot same history, 100% with cpu0 in max...

And my cpu goes from 41 degrees to 49 degrees ... just by putting Sio... because the cpu0 is in max constent... and yes the double frequency is not a bug major but he is very embarrassing:(...

:D sorry for my bad English :D

Thank you very much for your hard work DooM
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Finally found the bug.. It was Antutu benchmark's bug.. 3D GPU score was 0 whenever the 3D testing started to crash after 2 seconds.. That's why i was able to get low scores like 8000 or 9000 odd.. Because 3D score was 0.. So nothing wrong with DooMKernel, i personally tested it on Stock kernel(LB and UB) different phones.. I mean both are SXS.. One mine, another friend's.. Kernel is great.. Thank you [MENTION=2784807]DooMLoRD[/MENTION].. :D
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
I saw the same ~9000 AnTuTu score twice when I was OC'd at 1728MHz [performance/deadline] and GPU 3D at 320MHz.

In my case it was because the AnTuTu v4.0 3D test dropped out before completing.

You could see it start the 3D graphics test and displayed a few seconds and then dropped back to circular progress wheel, then moved on to I/O test, before completing with score of approx 9000.

In graphics tests like Epic Citadel and 3Dmark, I'm seeing the CPU temp get up to 44C, but it's not exhibited any thermal step-down to date.

I have seen this in the past using RaymanFX ICS OC CPU/GPU where heat scaled back the processor, but I think this was above 48C.

The day time temperature is currently 11-16C outside at the moment.

[Sony Xperia S, Acro S, Ion] denslife16:

Battery good thus far

I'm doing a 24hr battery test. I have my phone charged to 100%. I'll leave it without touching it and thus, will have the system/background(my background) use.

Anything beyond this is purely user activity and/or user preferred configuration. I'll be slightly miffed if I get 11% battery loss in 24hrs.

Just had a wee peek and I have lost 5% after 13⅔ hrs :fingers-crossed:

And that's with a stock ROM, bloatware removed, DoomKernel v6 plus battery monitor, email with 6 accounts, WhatsApp. plus a few others.

I haven't even started tooling around with build.prop and etc yet. :cowboy:

I read Stamina mode is a candidate to be added to help manage battery use for those who are having problems,

I would suggest DooMLoRD and the other contributors are spoiling us. :)
