Installed DoomKernel v3 on Sony 6.2.B.0.200

Very pleased with the proceedings thus far.

OC'ing the GPU gives some good 2D graphics improvements compared to DoomKernel v1

From my observations I'm not seeing this transition through to gains in 3D graphics.

Epic Citaldel returns 28-30FPS @ 1512MHz on high quality, where I would have expected better than 32FPS if it was to better an OC GPU on ICS

Running a 3Dmark test at 1.7GHz, an 320MHz GPU only gives a score of around 4000 where on a 1.7GHz OC GPU running ICS I was getting an Ice storm score of 4371

I did use DooMLoRDs fine small app to check I was on 320MHz GPU :D

Seeing really good (dear I say, unbelievable) improvements in the read I/O coming from the readahead setting.

Depending on the SDcard testing app, read verifies 20MB/s, 37MB/s and/or 50MB/s.

Writes are at 10-11MB/s.

This is consistently better than anything I ever 'gotten' on this device before. Top marks. :o

Battery life for me is great as seen on DoomKernel v1. As a benchmark of what the 'system' uses with no interaction we see the following.

It's not realistic given "nornal" use of course, but over a day at 9%, strongly indicates the system is not placing any excessive drain on the battery.

With improved/optimised governors in later DoomKernel versions, one would expect to better this battery usage.

Thanks again DooMLoRD for all your hard work.
[Sony Xperia S, Acro S, Ion] tOrNadO™:
I flashed this kernel in eXisTenZ ROM.. Its working great.. I was able to see a bit difference in the Benchmark results.. From 9000 to 9442 .. I also happened to see the ROM gettin a bit smoother as i use.. Will report about battery backup and other things after a couple of days.. Loved Dual recovery..

[MENTION=2784807]DooMLoRD[/MENTION] When i overclock the device i see the device getting heated up as i use.. Is it normal wen u overclock? :confused:

And can we expect Stamina Mode in the next release? :rolleyes:

Last but not the least, much appreciated ur work mate.. :cowboy:
[Sony Xperia S, Acro S, Ion] brown_89:
It's possible that this version (v03) makes vocal search doesn't working?
[Sony Xperia S, Acro S, Ion] malick186:
???

Can I flash this kernel in MIUI v5 ROM and some other JB roms or it is only for stock JB ROM??? :confused:
[Sony Xperia S, Acro S, Ion] akkiannu:
It's a kernel for stock ROMs. DooMLord is not gonna make it for custom ROMs not based on stock.
[Sony Xperia S, Acro S, Ion] Redstarr1:
Voice search works fine for me. Must be something else you changed.

It says in the OP that a stockbased Rom is a requirement. You know it's common courtesy to read before asking.

[Sony Xperia S, Acro S, Ion] Ned_Flanders:
I installed the Official Sony JB 6.2.B.0.200 ROM Pre-Rooted CWM rom and ran antutu benchmark (with stock kernel from rom) and got a score of 8941.

I have just flashed DooMKernel {JB}(v03)[20130608] and so thought i would try to retest the benchmark and the score was 8597.

Why the score lower?
[Sony Xperia S, Acro S, Ion] labrok:
Antutu is not reliable, for me one test says 7900 and the other one 9202, Cpu Floating point test is not giving accurate results.

how to oc gpu?
[Sony Xperia S, Acro S, Ion] davidbar93:
Read OP.

DooM ,I think fastcharge doesn't works. I only get 650-750MAH and I'm charging with original EP850.
[Sony Xperia S, Acro S, Ion] ishaan6698:
did not get it

---------- Post added at 06:09 PM ---------- Previous post was at 06:07 PM ----------

did not understand it
[Sony Xperia S, Acro S, Ion] nagug:
Kernel tuner is not working for me. unable to increase the GPU clock. its as if its locked. Any other tool suggestions?
[Sony Xperia S, Acro S, Ion] ishaan6698:
Yes exactly
[Sony Xperia S, Acro S, Ion] davidbar93:
OC manually with Terminal Emulator
[Sony Xperia S, Acro S, Ion] Redstarr1:
Well I'm using v3 and KernelTuner says Fastcharge works. I also tried it with that CurrentWidget and my result was fluctuating between 980 and 1080 mA for a 1200 mA charger. I think that's the full power my charger can deliver, it's already a few years old (my phone came without charger). At least that's more than 750 and there's always some fluctuation for chargers this size. I have proof for both:

CurrentWidget max result

KernelTuner: Fastcharge = OK

There can be a lot of reasons why your charger offers less current than what you're expecting. Do you have several devices plugged into the same socket? Might be some interference. Or the charger is ageing. What was the charge level of your phone when you were trying this? The higher the battery level, the smaller the current it draws. I don't think it's kernel related anymore.. I'm using stock .200, what rom are you using?

Maybe you should be less arrogant to ask for thanks in huge letters in your signature, if you're only going to have to ask help for trivial matters. Check this to see how you use Terminal Emulator (you have to enter those codes in Terminal Emulator). But it works just fine for me with Kernel Tuner. You can test compatibility in Kernel Tuner, my results are shown above. It says GPU 2D overclocking = OK as well, but there's only one preset, so you can really only overclock GPU 3D (the TE guide also only speaks of 3D overclocking ...)
[Sony Xperia S, Acro S, Ion] Chris_Castro:
stamina

From what I could investigate, Doom would have to modify ramdisk to have stamina fully functional (aside the thread in the theme's section):

init.sony.rc, add at the end of the file:

# Native helper for SuperStamina

service xssm /system/bin/xssm

class main

socket xssm stream 0660 root system

Then Kernel would have stamina "support" but not UI. Then you should go to stamina thread and follow subsequent steps.
[Sony Xperia S, Acro S, Ion] tOrNadO™:
Well.. I did try the one present in the Themes section.. Its just a hpyo.. Only UI i guess.. It does nothing.. I mean only Stamina Mode.. Eco mode worked fine.. And i was merely curious about Stamina Mode is gonna come or not in DooMKernel.. ;)
[Sony Xperia S, Acro S, Ion] brown_89:
Sorry i know that maybe i'll go ot, but can you look at my problem i have posted here http://xdaforums.com/showthread.php?t=2316688 because this problem happened when i flashed the v03!!

Hey doomlord.. Will you implement minimum cpu frequencies down to around 30 mhz?
[Sony Xperia S, Acro S, Ion] Anicane:
Does someone have the fastboot binary files ? i can't find, i wanted to flash this kernal via fastboot.
[Sony Xperia S, Acro S, Ion] Felimenta97:
Pro tip: Formatting on TWRP recovery doesn't work, so you will have problem restoring stuff. I had to flash dual boot kernel to restore all the stuff. Stick to the CWM for now.
[Sony Xperia S, Acro S, Ion] d_ave:
I also have problems with Fastcharge - Kernel Tuner says it's off. Any ideas?

View attachment 2029744
[Sony Xperia S, Acro S, Ion] m1st3r1:
I think people are mistaking fastcharge and fast(er) charging. fastcharge is the ability to draw around 1000 mA when connected to USB (or it's called force AC toggle) this feature is kinda dangerous and doesn't always work (Google yourself).

Fast(er) charging is the ability to take more amperage from bigger amperage output charger. Stock kernel has this feature already, and unless the dev modified this feature in kernel (like first version of Nova kernel back in the days), this feature will always on (provided that you have bigger amperage charger output)
[Sony Xperia S, Acro S, Ion] d_ave:
OK, that's clear, but how come the genuine EP850 rated @ 1500mA is delivering only 750-850 top?
[Sony Xperia S, Acro S, Ion] ajeenkyabirodkar:
Is the value for 300 MHz = 300000000 in GPU OC?
[Sony Xperia S, Acro S, Ion] m1st3r1:
read the first post.. just extract the kernel.elf and flash it via fastboot.

here's what other user said:

it's not fastcharge though, but stil fast(er) charging is working.

and dont forget that your phone takes some amperage to for some stuffs.. so try charging in 2G mode and data (& roaming) disable. better still try charge it in airplane mode. it'll definitely take more amperage. well, unless the electricity in your place is sucks and/or your charger (or the cable) is broken.. :)

yeah.. it's 300 x 10^6 Hz,, :D
[Sony Xperia S, Acro S, Ion] jhodax:
Question

... this kernel has some kind of improvements in battery life or is only focused in overclock everything?, I am sick with the battery of the Xperia S...
[Sony Xperia S, Acro S, Ion] RHBH:
In this zip there are the fastboot, adb and fastboot usb drivers.
[Sony Xperia S, Acro S, Ion] Redstarr1:
Oh I've found it, you still have to enable it in Misc (if you're using Kernel Tuner). That doesn't change anything for the current of my charger though, it's still around 1,1 A. If you add my power consumption (forgot to take that in account), the total power is quite a bit above what my charger is qualified for. When connected to USB, I only have about 0-200mA charging current (fluctuating a lot! But I'm using a rather long wire) without Fastcharge enabled (the power usage of the phone when not connected was around 200-300mA, so if you add that up, you get to 500). With Fastcharge enabled, results are pretty much the same (I might have to reboot?). But from what I know of motherboards, regular USB connections can't provide more than 500mA. Nowadays you have motherboards with a few high power USB 2.0 connections for charging tablets and phones, but mine is a bit older. So I'm thinking if you want to notice this, you need a pretty new pc, and I don't know whether laptops even have high power USB connections.

Odd thing is that Kernel Tuner also says that Vsync is off (isn't that part of Project Butter?).

Try a different power socket. Do you share a socket with several devices? Also if possible try doing this in a different room (on another power circuit) or even in a different house.
[Sony Xperia S, Acro S, Ion] ajeenkyabirodkar:
Just want to report that I'm still facing the flicker issue while pulling down the notification bar even on 300 MHz GPU OC with performance governor (as suggested by some users) and GPU rendering active. Everything else is top notch, keep up the good work, Doomlord. \m/
[Sony Xperia S, Acro S, Ion] tOrNadO™:
This kernel stuff is a lot of headache.. Isn't it? Lot of guys are interested in Fastcharge.. I happened to see USB charging has improved drastically.. Previously when connected to USB, it used to charge very slowly.. Like 1% in 2-3 mins atelast.. Now i see it charging like its connected to the charger... That's Faster Charging i guess.. :silly: And i was able to overclock GPU, but only 3D as u can see the SS.. I am not able to overclock 2D.. Its acting as though its locked to that frequency... :confused: And FastCharge can be turned ON by going to Misc in Kernel Tuner.. Its a good app.. And there's another main problem, when i overclock the CPU, i am able to see the phone getting more heated up.. It isn't the case with 1512mhz.. Doesn't any prob occur? :confused:
[Sony Xperia S, Acro S, Ion] guidoido004:
It may be something wrong with voltages, maybe they're too high. But for some reason I can't UV... Never managed to do so in dooms kernel...
[Sony Xperia S, Acro S, Ion] chevo21:
I have succesfully UV almost all (high) frequencies by 125mV since v01 (low frequencies cant UV less than 775mV)
[Sony Xperia S, Acro S, Ion] guidoido004:
there must be something wrong with Fauxclock then, will report to the dev and see if he know about this issue... thanks to the info.

NTFS Support.

I just connected an NTFS usb drive through OTG, it says filesystem unknown.

Any idea why ?
[Sony Xperia S, Acro S, Ion] m1st3r1:
It's because the kernel doesn't support/read ntfs format/file system (and I haven't find any kernel that support ntfs too).

Well, u can easily download paragon ntfs & hs in play store which can mount ntfs perfectly.
[Sony Xperia S, Acro S, Ion] aniket_:
I know the kernel doesn't support NTFS. But if you trace the quotes back(http://xdaforums.com/showthread.php?p=42191688#post42191688), you'll see that I requested him for the support. He said, it would be present in v2. Hence, the question!

And, kernel support is always better for me than an app ! :cyclops:
[Sony Xperia S, Acro S, Ion] Redstarr1:
There's no mention of NTFS in the features or changelogs (see OP). Doomlord might have said he'd implement it, but probably didn't get around to it yet.
[Sony Xperia S, Acro S, Ion] hdc:
Hello,

can I flash this kernel on this ROM?

Thanks!
[Sony Xperia S, Acro S, Ion] guidoido004:
It run only with Sony's stock out based on it. Not in aosp. ;)
[Sony Xperia S, Acro S, Ion] brown_89:
I think this kernel is only for stock jb,i'm sorry!
[Sony Xperia S, Acro S, Ion] element800:
No , you need to be on Sony 's stock Jellybean.
[Sony Xperia S, Acro S, Ion] m1st3r1:
maybe, this is your answer:

it's the same with this kernel (doomkernel) without rom support, it cant do anything.

searching around:

http://xdaforums.com/showthread.php?t=1724078 or just use the app i mentioned earlier.

maybe i was wrong, but afaik, the default 3.x kernel is already capable to read ntfs, that is as long as the rom support it. it's different than exfat.
[Sony Xperia S, Acro S, Ion] glenkocco:
just flashed v03 and i noticed that i always have cpu1 on max freq (1728), while cpu0 is on stock 1512.. i hoped that the fixes worked :crying:
[Sony Xperia S, Acro S, Ion] FenrirMX:
That's a big, fat lie. I've used my NTFS formatted external HDDs on my phone using stock. Which, of course, has no kernel or ROM support for it.

Just make sure you're rooted and get an NTFS app.
[Sony Xperia S, Acro S, Ion] cities516:
Kernel Tuner > Settings > General > Prevent Changes from other app

But this will keep CPU1 on, so I disable it.
[Sony Xperia S, Acro S, Ion] m1st3r1:
excuse me.. i think you're misunderstood or something. how do u know there's no kernel support? read that thread again. even the 2.6.x kernel android has already supported reading ntfs (but not write), so the implementation in the rom (hence, rom support, and like i've said, just use the app) is different. so, what i meant is: android kernel 2.6 - 3.x has already support read ntfs, but they need rom support (we can called it driver, etc), that thread (ntfs-3g) or that app are the "driver" hence they're rom support..

i hope you're understand.. :)
[Sony Xperia S, Acro S, Ion] mred88:
does the mount usb in cwm ok on this kernel?
[Sony Xperia S, Acro S, Ion] DooMLoRD:
it depends on how much charge u currently have... i have noticed that on some devices after 85% the charging slows down...

yes it will be implemented in next release...

i will add support for it in kernel ramdisk but is there any port that actually works?

yes thats fastcharge... it forces to draw 1000 mA if the connector supports it...

i have tried to incorporate features with which both kind of users, the ones who want battery life and other who want performance, will be catered to... try it out yourself and keep tweaking till u get the sweet-spot for ur device and ur usage...

i will added 2D O/C in next release...

overclocking WILL cause heating issues...

ODD.. i will check up with one if i can find a NTFS usb stick...

its been enabled in v03:

https://github.com/DooMLoRD/android...mmit/b3f7b4e98af0c397f59cfaacfb106b14362b3ff2

not yet... i will fix it soon...

BTW any improvement on the GPU o/c front?
[Sony Xperia S, Acro S, Ion] nagug:
As expected gaming with GPU OC uses more battery. Otherwise no issues. Battery usage overall has increased with processor OC to max and GPU OC to max. But not to an extend worth complaining. So that is ok. Probably right Governor + scheduler would address that.

Overall fine. Looking forward for next release.

One quick question...(jumping the gun here...) Do I need to reset my clock settings for GPU and CPU before I upgrade the kernel?
[Sony Xperia S, Acro S, Ion] DooMLoRD:
shouldnt matter as kernel ramdisk will reset the clocks anyways ;)
[Sony Xperia S, Acro S, Ion] hololodilolo:

[Sony Xperia S, Acro S, Ion] Chris_Castro:
Stamina

i will add support for it in kernel ramdisk but is there any port that actually works?

We don't know yet. But, AFAIK ramdisk is the missing piece. If that doesn't work, then we will have to dig deeper.

Anyway, thank you for enabling support!!!

DooM ,I really can't understand why I have lags when GPU OC'ed to 320Mhz. Also on 300Mhz.

What is the problem? Also flashed JB FW again now and flashed the kernel ,but the problem still exists.

And another prbolem that I got is that "Media" keeps awake all the time and it drains my battery. Tried to flash clean rom again and again but it still exists. [MENTION=2784807]DooMLoRD[/MENTION]

For all those with problems with overclocked GPU, hei1125 had lots of problems with this: http://xdaforums.com/showthread.php?t=2031064&highlight=1+51&page=92 so he then removed GPU overclock.

I also have "Media" sucking a lot of battery juice. Packages are Download Manager, DRM Protected Content Storage, Media Storage and Downloads. Very odd.

Thanks DooMLord for all your hard work!
[Sony Xperia S, Acro S, Ion] Redstarr1:
Maybe you should properly read "how to evaluate battery life". The first day on a fresh rom/kernel says absolutely nothing, give it a few days. How are your social network services set up? Are you constantly syncing? Give us a log or something, or just the proper name of the service you're talking about, because I don't see Media anywhere in BetterBatteryStats on my phone. And since I don't have any "media" wakelocks, and I'm on v3, I'm guessing it's not a kernel related problem ;).

If you sync and push a lot of stuff with your phone, your battery is bound to suffer, just saying, don't blame it on kernels or roms.
[Sony Xperia S, Acro S, Ion] davidbar93:
This happens even after 3-4 cycle charges ,so I didn't wrote this because it happened after 1 full charge. I'm not using social apps ,only Facebook & Instagram and they are hibernated with Greenify. I use most of the day only Wifi ,not 3G(maybe 10 min in a day). I'm not syncing at all.

"Media" contains:

"DRM Protected Content Storage"

"Download Manager"

"Media Storage"

"Downloads"

And it has the "Downloads" icon that show up in the appdrawer. Also "Android System" has about 24-30 wakeups and drains my battery too. I can't understand it - On ICS I didn't had this kind of problem ,it's really bothers me.

I will try to set caps with an int.d scrit and report back.
[Sony Xperia S, Acro S, Ion] Dr Goodvibes:
I upgraded to 6.2.B.0.211 ROM without any problems.

Installed stock kernel and CWM, again without problems

Installed DooMKernel v3 on 6.2.B.0.211 ROM and all performing well without any noticeable issues at the basic user level.

I did note, that I was no longer able to get the same 'high' scores(9801) in AnTuTu and consistently seemed to be 200 points lower at around 9600, with only one peak at 9700. AnTuTu is just an indicator and we should NOT read to much into this, given DoomLoRD has indicated a DooMKernel bespoke to 6.2.B.0.211 ROM is yet to be released.

GeekBench on .211 gives a lower scores too, which I'm starting to think that .211 may not have the raw grunt of .200, with or without DoomKernel.

I have now upgraded to DoomKernel v4 and in general user terms, the kernel exhibits no 'operational' problems on 6.2.B.0.211 ROM that I have noted.

A couple of things I noted in 6.2.B.0.211 ROM.

HDMI via a HDMI switch and HDMI over a HDMI-DVI cable connection now works.

In 6.2.B.0.200 ROM (Only ever tested with DoomKernel v1/v3 installed) HDMI in the two cases above, HDMI connection would be detected every time, but only show a 'snowy' picture or nothing at all.

Tested again with 6.2.B.0.211 ROM and then 6.2.B.0.211 ROM and DoomKernel v3 and in both cases HDMI works.

I'd written off HDMI over anything but a direct connection, but it appears Sony may have 'tweaked' something to get HDMI via switch and DVI cable working. HDMI on 6.2.B.0.211 ROM with or without DoomKernel seems to noticeable lag on mkv (H.264,AC3) 720p movies.

A 1GHz CPU with PowerVR SGX540 gives a much better HDMI output image... go figure.

I note that the second CPU on both DooMKernel v3 and DooMKernel v4 places it's max freq at 1728MHz, even when set to 1620MHz.

I am using Google Play SetCPU to manage CPU frequencies and governors.

I note that in SetCPU the frequency level percentages only shows a use up to a max 1620MHz, but it doesn't show both CPU and my guess is, it's only monitor the first CPU.

I am using Kernel Tuner to view the CPU frequencies as seen below.

I have a max CPU set at 1620MHz and a min set at 192MHz. So, it's almost as if the second CPU is track some default setting of 1728MHz- 384MHz.

As usual, my thanks goes to [MENTION=2784807]DooMLoRD[/MENTION]
