UPDATE! Version 2 is OUT for Testing!

I´ve fixed the error on Camera and yet we have some extra FREE RAM!! Also I tested my Version 2 Kernel with the Official Release and it´s working ROCK Solid with no lags or whatever...

Grab the version 2 in 2nd post!

Please provide feedback as soon as you can.

Jimbo!

i'm amazed by this, now only waiting for final version sources and your kernel :)
[Xperia Arc Android Development] jimbo77:
Thank you for Testing!

Can you please share what your settings are? What Scheduler, Governor, Frequency?... What ROM are you using, so others members can also compare?

I'd really appreciate if you could provide a litle more detail on the feedback so I can improve what's not working as it should.

Thanks!

Jimbo
[Xperia Arc Android Development] gen_scheisskopf:
Kernel works very good.

However after every reboot governor is always Ondemand (should be conservative- set using SetCPU). Maybe setting Conservative as default would be a good idea?

Also could you enable lowest cpu clock (127 MHz iirc)?

[Xperia Arc Android Development] jimbo77:
Try VR or SIO... Both of them work good for me...!
[Xperia Arc Android Development] snuupy93:
jimbo77 - the link with modules update is gone... where I can get the modules, beacause, without them my wi-fi can't work, write "Wi-fi turning on....." and END... this is it... please, give a link to this modules.
[Xperia Arc Android Development] drew261920:
thanks im now using ur kernel conservative VR OC at 1.6 :D if i max it to 1.9 will it drain battery faster?

---------- Post added at 03:23 PM ---------- Previous post was at 03:22 PM ----------

i know its already included?
[Xperia Arc Android Development] snuupy93:
No, I don't think so, bluetooth, working fine, but Wi-Fi...
[Xperia Arc Android Development] jimbo77:
WiFi is compiled within Kernel, no need for Extra modules. I've removed the link since it isn't needed anymore, it was useful for V1 only. You probably come from DoomKernel, if so you have to flash Doom's stock WiFi Modules for your WiFi to work my friend :)

I don't think so, but I just found a F!@##$ bug with Conservative that will not allow the phone to go beyond 900MHZ (It will still be really smoth though you won't even notice it is running at that speed...), It's totally fixable and will be updated for next release ahhhh!! I thought this was going to be the final good Bug-Free Version :( :( :(

Anyway try using other governors like ondemand for the moment if you find Conservative "Slow" for the time being...
[Xperia Arc Android Development] drew261920:
whats ur kernel before flashing arc knight? do u wipe caches? because when i flash it wifi works no problem
[Xperia Arc Android Development] snuupy93:
Ohh thank you!

SECOND: will not allow the phone - YES, but after that, the phone says is it allowed, and in the superuser icon we can see the no frill CPU (I use) is allowed.. I overclocked my Xperia ARC to 1.6ghz sucssesfully.

I flash to DoomLord modules, but without sucsses, now im flashing brand new ICS and try again...
[Xperia Arc Android Development] drew261920:
hmm.. i dont find it slow? ..how to know that it cannot go beyond 900MHz? well ok ill wait for the fix :D its ok jimbo stay :cool:
[Xperia Arc Android Development] jimbo77:
Download CPU Spy (Free on Market) and it will tell you how much time the phone spends in each frequency... There you can see when using conservative governor the phone can't go beyond the 900MHZ even you OC'ed it to 1.6 GHZ..

It feels smooth, like running at higher frequencies... Sorry for that! :(
[Xperia Arc Android Development] drew261920:
its ok ill try :) ill use ondemand at the moment when conservative is not yet fixed :D

---------- Post added at 03:58 PM ---------- Previous post was at 03:55 PM ----------

jimbo cpu spy shows that 1.6mhz runs on conservative
[Xperia Arc Android Development] jimbo77:
That could be because you switched to Ondemand so if the phone goes even for 1 sec to Ondemand it will be shown there.

Hmm you're using Conservative or Ondemand? Why don't you test like for 2 hours using CONSERVATIVE only and do your regular stuff, play music, some games, etc... and then tell me if the phone can get up to 1.6GHZ...

That will help me a lot for debugging and trouble shooting :D

Thanks!
[Xperia Arc Android Development] drew261920:
ok :D im on conservative 1.6mhz when i switch to 1.9 it doesn't show on cpu spy. then i switched on ondemand then it shows then i switch again on conservative and choosing 1.8mhz and cpu spy shows that 1.8mhz conservative is used.. u need to change on ondemand first before conservative :D ill try conservative for few hours then ill report to you :)

[Xperia Arc Android Development] jimbo77:
Yeap conservative is buggy at the moment but I'm working in a fix right now.

Please use another Governor for the time being while I fix the conservative one...

my report: laggy when playing asphalt 6 HD in stock rom. after checking, you use 50000 sampling rate right? i change it to 20000. for ondemand governor, you set it up-threshold to 60 if i not mistaken, and power-save bias to 0. i change it to 95,35 for smoothness, and 95,95 for save battery. check this.

1.901 GHz not a stable Bro just restart or phone heating, almost 70% charge my phone, when i set the cpu control 245MHz to 1.901 GHz just restart and batter come to just 1% (Your Kernel is Monster or something BIG) first u clear the battery drain Problem.

[Xperia Arc Android Development] jimbo77:
I'm sorry I can't keep updating two versions at the same time. There is a Thread the Iris (Iridaki) created a while ago where she explains how to modify Ramdisk of kernel including change the boot logo to one of your liking.

Thanks for the testing and tip, I checked the link and also investigated a little and found it can help for performance, not sure for battery since the CPU will jump to higher frequencies more frequently. Anyway I've updated my Ondemand sources and changed what you suggested to see what's the impact of the changes.

Well, If you have an ARC (LT15) i wouldn't even recommend going beyond 1.4GHZ! Remember our Phone (LT15) comes with a 1GHZ Processor. so if you are pushing it to 1.9GHZ it means the power consumption and the heating will be also increased by 90% . It can REALLY harm your device if you do so constantly!

Higher frequencies (Above 1.6GHZ) are more useful for ARC S (LT18) owners since they are pushing their CPU around 20% more.

For me it is stable running at 1.2GHZ (LT15).

@ALL: Conservative bug has been fixed but I'll push new version tomorrow or Monday Night probably I need to do some test in some changes done not only to conservative, but also to Ondemand, changed the Memory Allocator, removed some debug options... meh some minor changes that can impact on performance but i need to test first and then I can share :)

[Xperia Arc Android Development] snuupy93:
Do you update v7 and the processor speed is 1ghz again or is it 900mhz like last time?
[Xperia Arc Android Development] jimbo77:
The problem is with Conservative Governor, if you choose Ondemand for example the phone can go beyond the 1GHZ (Up to 1.9GHZ if you wish). I've fixed such issue but i won't release the updated Kernel until Monday Night since I'll be busy the weekend and will have no time to test properly if it's fixed or not :)
[Xperia Arc Android Development] ascariz:
did you change the voltage? can u post here list of your voltage that you used for each cpu level? just wanna take a look. tq in advance..

Any clue.

ArcKnight v7 & Arconium 2.2

-works smooth, downclocked always to 800 MHz (I don't need more)

-there is no battery drain- ATM 30h since charged and still 40% left (and yesterday phone did a lot of BTS switching- business trip)

Programs that are likely to cause problems/battery drain or just don't work:

-SetCPU- it's not able to set governor on boot, sometimes doesn't set min/max clocks. Also caused system instability on my Archos Gen9 101 tablet (ICS 4.0.3). Not sure if it's responsible for battery drain but still it doesn't work right, use NoFrills Cpu Control instead.

-CurrentWidget- for sure causes battery drain. It seems to prevent CPU from going to deep sleep (constant power usage- 20-30mA or more instead of 6-7mA; measurements taken from battery chip directly so they are quite accurate). Uninstall if you have it.

-QuickBattery- widget doesn't refresh (but this might have been caused by CurrentWidget or SetCPU), one of replacements- Circle Battery Widget

USB-OTG

Hello,

thank you for your advice.

I didn´t know that there is any usbstorage module.

What is the right way to get the module working?

I guess:

Open Terminal

Type su

Type insmod /system/lib/modules/usbstorage

To get the module on every boot working i have to write it in a init.d script?

How to do that?

ArcKnight Kernel - V8 is OUT - Grab it in 2nd Post

Changelog:

[*]Reverted to Previous Conservative Governor Source - I need more time to fully implement the Smart Toogle into that, there is a problem with frequencies...

[*]Ondemand Governor tweaked once more based on recommendations from Ascariz (http://xdaforums.com/showpost.php?p=25406771&postcount=206). I made it 95/35 for smothness...

[*]Added Back Ext4 and NTFS File Systems support.

[*]Reworked Voltages table to match the original one (V1 Kernel)

[*]Added Full Support for user to contron VDD Levels through Sysfs interface...

[*]Fixed InteractiveX issue where the CPU couldn't go beyond 1GHZ, now it can go up to 1.8GHZ but need testing and confirmation from you guys...

[*]'Disk-On-Chip Device Drivers' Changed to "OneNand" - More info about OneNand http://www.businesswire.com/news/ho...sungs-OneNAND-TM-Flash-Supported-QUALCOMM-MSM

Regarding OneNand I need feedback from you guys, It could be placebo effect but my phone feels smoother than before.. Since OneNand improves read/writes speed from/to disk...

IMPORTANT

For Better user experience and feedback purposes it is recommended to use Conservative and Governor and CFQ as IO Scheduler, also if you are using and SD-EXT make sure to format it as Ext2 since it will provide you more speed and faster access to your applications and data stored there.

BTW guys I'm having such a hard time compiling new kernel version since my main computer broke and now I'm stuck with a Intel Pentium 4 (3.0 GHZ) with 1GB of RAM and when running Ubuntu from VMWare it runs with ony 512mb (So damn Slow) so if you wanna help me to upgrade (at least my RAM memory) don't hesitate on donating for the cause :D
[Xperia Arc Android Development] gen_scheisskopf:
Maybe adding ext2 fsck on boot would be a good idea? Just in case
[Xperia Arc Android Development] jimbo77:
That could be useful! I'm gonna add it by next version, it is just a small change on the init.rc file from Ramdisk to execute e2fsck.

[Xperia Arc Android Development] Tarzan-:
Jimbo thanks for your commitment with your kernel. I have come back to your kernel and its been working great for me.

A question, I'm not really a hardcore android user, you can say above average user, you reckon I should upgrade my kernel to your V8 (jeez I get goose bumps saying V8, coming from an Aussie lol) or just V7 is sufficient ?

Thanks
[Xperia Arc Android Development] jimbo77:
I'll said yes. Since it has small bug fixes with both Ondemand and Conservative. In V7 the Conservative Governor was misbehaving and causing the CPU to stay lock at lowest frequencies (around 900MHZ) and doesn't allowing it to sleep properly. So V8 will give you more stability and Battery life plus I've added Voltage control so you can now lower voltages for each freq and extend a little bit your battery life by consuming less power for each cpu freq.
[Xperia Arc Android Development] Tarzan-:
Cheers for replying.

I have read first 3 posts and couldn't find best practices/settings for your kernel, could you please post settings for both performance and battery for curious users like us.

I always carry my charger so I need best performance with no lags.

P.S What kind of ram you looking for ? I have 4GB (2 GB each DDR ram) if needed pm me. :)
[Xperia Arc Android Development] jimbo77:
I've using CFQ as IO Scheduler and Conservative as Governor, but if what you need is smoothness go with Ondemand as your Governor and OC the Phone up to 1.3GHZ (If you own an LT15) or 1.7GHZ if you own and LT18, don't go beyond those freqs since it can really harm your phone...

Also using EXT2 as SD-EXT increases the performance of apps stored there with Link2SD...

Regarding the RAM i need a DDR2, I can tell you is really a Pain in the *** to compile using 512MB RAM in VMWARE player lol...
[Xperia Arc Android Development] Coolgoly:
Jimbo I have a question for you.Voltage in deepsleep is the same used at 122MHz(lower cpu freq.)or not?

Thanks for the voltage management,now I can undervolt to my custom table,750mV@122MHz\1200mV@1500MHZ.
[Xperia Arc Android Development] peacekeeper38:

@jimbo77

I found a great thread regarding

Kernel Governors, Modules, I/O Schedulers, CPU Tweaks, AIO App Configs

It also says that

"

Q. "Best I/O Scheduler?"

A.There is nothing called "best" i/o scheduler. Depending on your usage environment and tasks/apps been run, use different schedulers. That's the best i can suggest.

However, considering the overall performance, battery, reliability and low latency, it is believed that

SIO > Noop > Deadline > VR > BFQ > CFQ,

given all schedulers are tweaked and the storage used is a flash device."
