I'm on EW JET 2.1.B.0.1 Xkernel.X2.77e , on 20072011 zkernel maybe modified by Erick., BB .54

down to 50 % after 11 hours of usage on 3G

display ON time is 2h 45mins

brightness set to 60% through out

40-50 sms texted

browsed xda on wifi n HSPDA

downloaded some apps from market

played around with UI n ADW themes

signal reception is very good and not draining battery at all, idle standby has significant efficiency

reasonably smooth and no lags at all , no reboots or wlods at all

only thing i wish in this kernel is highest frequency to use 1250 mV (even if its 998 or less, cos don't wanna use setCPU again n forever ) and better undervolting like doomlord's v02e voltages probably
[XPERIA X10 Android Development] zdzihu:
Hi n4naveen,

For now, stability > performance.

Still, as soon as the kernel gets 100% stable, I will be pushing voltages to the lowest possible :)

Cheers,

z
[XPERIA X10 Android Development] n4naveen:
I never faced any kinda reboot/WLOD/lag with all your kernels

I've used

22062011 modified by azuzu for froyo on WB CM 6.1.3 006v with .67 BB

14072011 modified by doom for froyo on WB CM 6.1.3 006v WITH .67 BB

and now 20072011 on erick ROM with .54 BB

interactive gornvernor is very effective, i think you may also implement the "smartass" governor which is even better AFAIK

I felt like stock kernels and that's why i'm looking for best voltages :-D, anyways i will wait , Thanks for the reply. :)
[XPERIA X10 Android Development] Carlo_WPG:
Just installed the failsafe. I'll test it out over the next few hours to see if I get reboots. I still haven't installed SetCPU - just haven't had much time at work today - might have to wait until the weekend at this point.
[XPERIA X10 Android Development] zdzihu:
As soon as we manage to port undervolting via userspace (which is WIP now), you will be more than happy :)

Cheers,

z
[XPERIA X10 Android Development] n4naveen:
sounds really cool :)

hope you will also have a look at "smartass" governor if its better

Bug report for zkernel 20/7

Playing music via Bluetooth on headphones lags at every 2 seconds... its like playing and pausing every 2 seconds.. can confirm this bug because after switching back to zkernel 14/7 there is no such bug
[XPERIA X10 Android Development] Mayazcherquoi:
I've only had two random reboots with your 20/7 fail-safe kernel since I installed it (last night, around 16 hours ago). I also wasn't doing any very processor intensive work.

Z kernel 20072011

ROM CM7 7.0.3

Testing now for nearly a day, using setcpu set to interactive using highest and lowest frequencies i have had no reboots and battery life for cm7 is above what i usually get, i have done away with screen off profile because i tend to agree with z in there is no point as your phone is asleep anyway. Response time is fast, screen off animations are fast, playing 1080 hd videos through youtube work flawless with no lag, overall a great stable kernel.

I will today do some testing on the failsafe kernel and see if there are any differences in performance and stability with that one.

Great work as usual Z, thankyou.:)
[XPERIA X10 Android Development] baz@gmx.co.uk:
@ Z, both 2007/failsafe have given me reboots. 2007 - while screen was off.

Failsafe, twice just after boot completed.

have had to re-flash as normal kernel started to also :eek:

[XPERIA X10 Android Development] riginal:
20072011 was doing pretty good with interactive then I installed an app called osmonitor & messed everything up, osmonitor has the ability to set governors too & it was ondemand by default, So I changed it to interactive but the "getting stuck on a freq." issue returned & no matter what I did, I removed that app, changed the govenor in setcpu to ondemand & it worked fine but changing back to interactive had the same old getting stuck issue

I went ahead & installed the failsafe version & at first I had terrible freezing issues but wiping cache & dalvik cache solved it so I guess maybe it was a rom issue?

anyway but still in failsafe on interactive mode, freq. gets stuck too, no matter what I do, But other than that it's stable & I haven't had any reboots or wlods yet( a few hours)

I'll flash another rom & try it on them too

20072011 failsafe

After 24 hours, the failsafe version on stock 2.1.B.0.1/bb .67 had no reboots at all, using SetCpu OnDemand governor, seems as a real, daily usable one. Battery life slightly better than on stock kernel, and lacks of lags.

Thanks Z! :)
[XPERIA X10 Android Development] jon08:
Sorry if this was already asked but what is the difference between the normal and the failsafe version?

Thanks :)

Been running the fail safe version since it was posted. Happy to report that I have had no reboots at all. My unit does not like OC for some reason. Running happily along.

Report:

on zkernel 20072011 i tried bb .67 from yesterday, 3g very fast and it was working ok until middle today, then got 4-5 reboots in 2 hours so flashed back to bb .54 and no more reboots.

Now just flashed the failsafe kernel and will see if it will be stabile, more reports to come.

Z kernel 20072011 Failsafe

ROM CM7

Have been testing all day and found screen freezes have happened at least 3 times all involving the phone waking up and attempting to either open or begin using a app those being browser, xda app and player pro, i had governor set to ondemand.I have not had any screen off reboots and battery was about my normal usage compared to other kernels with no noticable improvement.
[XPERIA X10 Android Development] zdzihu:
Hi guys,

So I spent some time testing 2007 series, and here's what I found out:

- first of all, 95% of users are not affected with this probem (whyyy :confused:)

- there's no random crash/wlod... it's not random at all, only happens after unlocking the screen

- it happens regardless of overclock/undervolt/min-max frequency used

- it happens only with interactive governor

Can anyone confirm they experience the same problems? If that's confirmed, it will be easier to address the issue :)

Cheers,

z
[XPERIA X10 Android Development] colossus:
Hi Z,

would it not be a good idea for you to set up some setting/profles we can use in setcpu that those wanting to test can use so we are all using the same frequencies etc, seems to me we are all using differant profiles and governors, could you post some guide lines for us to use.;)
[XPERIA X10 Android Development] riginal:
Hi Z

My report on Cobrato's gb is in previous page

so now I'm on Achotjan's 2.2 aosp rom, I flashed the latest kernel version(not the failsafe one) & deleted those troubling lines in hw_config & I noticed that in interactive this time I have the opposite issue of getting stuck, the freq just jumps from one to another & never becomes fixed, even if I kill all the apps in background & don't even touch the screen, it just keeps jumping, Ondemand works fine though

No reboot or wlod in interactive mode in both roms
[XPERIA X10 Android Development] Eustachy_Kapusta:
i'm using 20072011 failsafe with cobrato's miui 1.7.15 and i didn't have any wlods, reboot etc. there was some lag but it isn't something big, but i can't set governor to interactive as it stuck at one freq, so i changed it to ondemand and it's working great
[XPERIA X10 Android Development] mohdameer:
hey z,

i am using the 2007 normal kernel, no crashes, however, most of my problems are during restarts. it takes ages, and sometimes reboots a couple of times. seems like restarting after wiping dalvik cache
[XPERIA X10 Android Development] viewdetails:
For me, the reboots are started while the device was on the desk and locked (and I noticed, the SE bootscreean suddenly appears), later twice, it was unlocked and in use, but not in the moment, when I unlocked the screen. The governor was ondemand (set at boot), and there were no profiles defined in SetCpu, caches were wiped before install.

The same settings applied now on failsafe, and there were no reboots since I flashed it. :D

Edit: maybe the ondemand causes the issue on normal kernel?
[XPERIA X10 Android Development] hurstov:
@z

Got 2 X10's, One running 2007 standard on 2.1, one running 2007 standard on CM7. The 2.1 rom is flawless mate. not missed a beat, no reboots, perfect. But i'm gettin the stuck at one frequency(SAOF:D) on CM7. Do i need to delete those lines or is that just for froyo? No reboots tho!

Cheers dude!:)

Edit: both using interactive profiles. if i use on demand all profiles are available
[XPERIA X10 Android Development] bharadwaj1991:
+1, exactly what happens with me. after i unlock the screen after it has been in deep sleep for a while...the phone gets stuck and freezes..i have to pull the battery out. i even set the minimum to 245mhz...and it is happening less now..but still there.

Z kernel 20072011 Failsafe

seems stabile, no issues at all since install about 6 hours ago, tried to stress the phone

just to get it to reboot or wlod, but nothing yet.

[XPERIA X10 Android Development] Carlo_WPG:
I've been using the failsafe version of 2007 for the past 24 hours or so and no reboots. I've even messed the hell out of my link2SD settings (was playing around with the second partition in GPARTED :p) and I have not observed a single reboot of any sort - Just the expected FC's from the apps that were no longer linked properly on the SD Card due to my messing around (fixed via reinstalling the affected apps).

So far for me the 2007 failsafe seems to be the most stable. It has had some laggy moments with the Live Wallpaper I'm using, but that's nothing new. Had no lag with the previous kernel, just reboots and loosing the SD card. I've also noticed a very long bootup time, but I'm not to worried about this as the phone works well and I'm saving on battery so I can't complain :)

Phone Info:

model:X10a

Firmware: 2.1-update1

Baseband: 2.1.67

Kernel version: 2.6.29-zKernel-20072011

Build: 2.1.1.A.0.6

Network: Rogers (Canada)
[XPERIA X10 Android Development] Mayazcherquoi:
Running stock 2.1 with baseband 67, I can confirm all of the above (the system crashing/rebooting after unlocking the screen). I am using the fail-safe kernel.

Also, after I first installed this kernel, the interactive governor wouldn't scale. But after the first reboot (which, I didn't do, it crashed itself..), the interactive governor was scaling. Also, unsure if this matters but I'll state it anyway, I've set the maximum frequency in SetCPU to 576MHz for the past day, otherwise Interactive will always seem to scale to 998MHz...

Also, if possible, please implement off-line charging! I almost had another experience (see aforementioned posts by me with a link) that would of almost left my phone dead (fell asleep with a phone call on via 3G [turned off after 376 minutes], with WiFi on, and woke up after 6 hours of sleep with 3% battery [from a full 100% 6 hours earlier!]).

Regards,

Mayazcherquoi.

[XPERIA X10 Android Development] Mayazcherquoi:
What just occurred now: after 40-odd hours of uptime, I got hit with a crash and from then on a boot loop. Happened while locking the device after closing Handcent SMS.

EDIT: Taking out battery does not help at all.

EDIT2: Turns out it was SetCPU... It was stuck on a maximum frequency of 245MHz. So, before it could start on system boot, quickly went to the application drawer and set the maximum frequency to 998MHz. I doubt this, but, could SetCPU be the root of our crashing problems?

[XPERIA X10 Android Development] Nikhil_007:
Hi z. Used z kernal 20072011 for like 2 days before giving up on random reboots. Switched 2 goto's kernel since then well ur observations r totally correct. Felt the same way. The way I think is if u set out to 19mhz clock speed. Sleep of death r more common (phone never wakes up, but reboots). And sometimes if there is a sms or mail & I rush into opening a screen without giving 1-2 sec, it gives a wlod.

Another interesting observation, may b it just happens with me, I get more wlod while waking up phone by pressing power button, but if I press home key its less vulnerable..it sounds stupid but don't know y. I am using WB 008.1. Rom.

Also I think goro's kernel gives less wlod. (around 1-2 a day) may b he has added something, or may b messed with something. U can confirm with him.

May b my review is of some help here.

IF and only if you can't find the info your looking for in the above thread, if you search this very thread, you will find very crude instructions of how I got things to work. As I said my instructions are crude at best and not the most ideal. The information in the sticky thread mentioned by Doom (Found at the top of the X10 Developers forum - you really can't miss it) should contain all the information you need.

Cool z! Excellent. I will play with it ..

Is it possible to have the "Stop app via long-press" to kill the foreground application ? Although I understand that normally people use the same apps and thus is more efficient to have them in memory ready to go, I just hate Skype :) and I want phone to be responsive, not to start cleaning whenever I decide to start other apps. I know I won't use skype anytime soon.

If we can't have this android cyanogen behavior, I will have to create a kernel module that just kills the PID of the app that you write to a sysfs file and then a small Activity that waits for long back press.

I hope is doable ..

Should we use the audio stuttering fix with this kernel or is it fixed?
[XPERIA X10 Android Development] zdzihu:
Stuttering is not kernel related, it's a ROM problem.

That would require decompiling and hacking SEMC framework. Or writting an extarnal app.

Install the old xRecovery (the bad one for 2.3.3, 0.3 from latest Flashtool(not 0.3GB!))

Download xRecovery_0.3_GBready.zip and put it on your sdcard (dont install it now)

Reboot into xRecovery from Flashtool

Write this with adb shell (USB debug and unknown sources on)

rm -r /sdcard
mkdir sdcard
chmod 777 sdcard

and then flash xRecovery_0.3_GBready.zip, reboot and flash kernel, it should work
