Long time lurker.. and probably my first post.

Firstly want to say a huge thank you for your efforts... your Kernel singlehandedly made my Sensation (which was a replacement for my many broken phones including sgs2) easily the best phone i've ever had.

Unfortunately, my sensation is now doing that weird unresponsive touchscreen issue. Touchscreen only works in 4EXT recovery and MIUI roms despite wipe/format/flash/digitzer calibration/ hboot upgrade/downgrade.... therefore i've moved onto an HTC Vivid/Velocity 4G.

I am willing to pay/donate (and i'm sure others there will be too) for you to port over to that phone.

***EDIT***

Oh btw... neither of your Kernels will allow wifi to turn on in MIUI ive tested r19/19.5 of the non-sense with and without BCM4329 as well as your sense based kernel... hence the extra reason i'm not staying with the sensation because the only rom that works cant use wifi :(

Please let me know what you think.
[HTC Sensation] Sultanxda:
The only complication is that I don't actually own the phone so I wouldn't be able to test the kernel on it. That basically means that I'd be working blind.

HOWEVER, it seems that Faux has a kernel there and from the looks of it the chipset in the HTC Vivid is the same as the chipset in the Sensation, so starting off might not be very difficult. Also, as you can see, I deeply enjoy kernel development :D

The verdict: I'll think about this and I'll try building a kernel for the Vivid and I'll PM it to you. If I am unable to build successfully or I encounter a complication of some sort then I will also mention that to you. I'd also like you to know that maintaining a kernel for a device I don't have is much more difficult than maintaining a kernel for a device that I do have so updates wouldn't be released as often as they are for my current kernels for the Sensation.
[HTC Sensation] dsp26:
Completely understand and don't want to hijack any further... happy to continue over PM :)

Just waiting on your aroma build now to test if the wifi works on MIUI as i'm selling the phone with MIUI

Slow Boot

First of all Thanks for your hard work in making such kernels available for us. Really appreciate your efforts.

I have flashed r19.5 and running Albinoman's CM10.1.

After flashing my phone takes around 30sec to boot. The HTC screen is present for 20 sec and 10 sec for CM animation.

Earlier with the Kernel provided in the rom it use to take not more than 10 sec to boot (Including HTC and CM animation).

Please suggest..!!

Edit: I updated to r20b5. But the boot is still slow.
[HTC Sensation] Sultanxda:
That's because of LZO compression. LZO compression makes it boot a little slower but the kernel itself runs faster.
[HTC Sensation] EfrainTrejo:
No more boot loops on r20b5. Running cm 10 nightly. :victory: :good: :)

So 2nd phase and else from intellidemand is in fact forking?
[HTC Sensation] Sultanxda:
In this case, Kernel Tuner is not the one at fault. I just checked and rq005 is right; 2nd phase frequency isn't there for Intellidemand. Today I'm busy so the new release will come tomorrow. Adding the 2nd phase frequency for Intellidemand is trivial and only takes a few seconds.

[HTC Sensation] CRACING:
Hello android1234567, There is a bad news. Temporary bootloops issue has started again after flashing r20. :(

I did a fresh install of albinoman887's Feb 15 ROM and your kernel r20.

And upon returning to r20b5, the issue gone away.

I also tried powerful mod reset on r20 but still have same problem.
[HTC Sensation] Sultanxda:
CPU bus bandwidth settings were changed; remove any automatic overclock you have set on boot. Previously, the bootloops were caused by a certain build flag, but r20b5 has the exact same build flags as r20.
[HTC Sensation] CRACING:
hmm, I haven't made any overclocks. Instead used whats recommended and default selected settings on r20 aroma. Also its my fresh ROM install. No cpu modification apps installed either. i.e android tuner

The difference I have noticed is, on all betas of r20 kernels except r20b5, I used to get many bootloops before the OS boots up (i.e 3 - 5 times) but on r20, I get two bootloops and then the OS boots up.

BTW; you still awake? its 2 am there I suppose. :p
[HTC Sensation] Sultanxda:
Did you install the kernel right after doing a fresh ROM install? Install TamCore's kernel, let the phone boot up completely, reboot to recovery, then flash my kernel.

Nothing significant changed between r20b5 and r20, otherwise I would've made an r20b6.
[HTC Sensation] CRACING:
No, because I know flashing the kernel right after flashing the ROM causes bootloops. So I let the ROM boot after flashing, then return back to recover and flash the kernel.

Ok I will try TamCore kernel.

I see
[HTC Sensation] CRACING:
Unfortunately it didn't helped. Of course TamCore kernel didn't had that issue but after flashing r20, the issue started again. :(

I have uploaded a video here.

Re: [KERNEL][LINARO][JB&AOSP ICS][FASTEST][3.0.64][Aroma] Sultan kernel [r20 2/15/201

I cant make your kernel to work with albinos's rom.... settings wont stick.

Edit. I flashed it with a clean rom installation and now it works.

Edit1. How do i change color depth to 32bits? i saw it in kernel tuner.

Edit2. I also saw in kernel tuner the option of turning on/off USB OTG, i thought it was working by default.

Edit3. Glad to see you used the modified script i sent you with Readahead cache size option.

r2.5 released!

Thank you to everyone who tested the r2 series and helped me find a suitable L2 cache frequency (it's now set at 1.62GHz, ALL the other kernels have it at 1.566GHz ;) )! Now all of us should be able to overclock the CPU higher than with any other kernel for the Sensation (if you can't then your max frequency should be more stable now)! There is also a 1.836GHz flavor now! Enjoy, and be sure to give feedback on how it runs!

We'll see how it runs for everyone else. I'm sure if you run Antutu a few more times you'll score even higher ;)
[HTC Sensation] snakebiteex:
awesome kernel.. super fast..

but one thing that prevents me from staying with it is the lack of zram or swap support..
[HTC Sensation] Sultanxda:
Thanks for your feedback. I'll add it in r3 which will be coming out very soon (it'll be built once the number of voters in the poll reaches 100). R3 will feature the 3 winning CPU governors and zram/swap support.

[HTC Sensation] Sultanxda:
r3 kernel

Ok, everybody. I've already created the r3 kernel and tested it and it works but I can't release it until the poll reaches 100 voters. R3 has swap support, zRam support, CIFS support, TUN/TAP support, Intellidemand, Ondemand, and Badass (everything except for the CPU governors and swap support are modules so they won't slow down the kernel and make it huge). Those 3 CPU governors may change according to how the poll ends up. The release of r3 is up to you guys, so be sure to vote!

after installed pure jb rom(not booted), i installed your kernel .not boot show splash logo next reboot splash logo. not boot old version is no problem. r2.5 had a problem. i tested other kerenl(dk,tamcore,bruce.frank) no problem.
[HTC Sensation] Sultanxda:
Let it boot first then reboot to recovery and install it. Also, use the 1.512GHz r2.5 version if you're saying that r1 and r1.5 didn't have any problems.
[HTC Sensation] Sultanxda:
r3 released

I'm releasing r3 of my kernel because with only 11 votes to 100 it is impossible to change the ranks of the 3 winning CPU governors. R3 features swap support, zRam, CIFS support, TUN/TAP support, Intellidemand, Ondemand, and Badass. Thanks for voting!

My goal for r4 is to make the kernel even lighter since the addition of those CPU governors made it bigger. R4 won't be released as fast as the other kernels were because I have school this week. Does anyone here use USB OTG?

When I tried using Kernel Tuner it caused the same problem for me :confused:. Uninstall it, reboot your phone, and install Android Tuner for free from the Play Store.

EDIT: The problem Kernel Tuner caused for me was that it shut down core1 and I couldn't turn it back on/change any of its settings. Don't know whether or not that's the problem you're having.
[HTC Sensation] ardom:
Yup that's my concern. I followed your instructions. Installed android tuner. At the first few minutes it is working then maybe after 10 mins i noticed a slowdown. Then i checked my 2nd core its offline again. I wonder what could be causing it to act up like that?

[HTC Sensation] Sultanxda:
That's weird. Might be another application too. I noticed this behavior with BatteryStats as well. As far as I'm concerned, those are the only 2 applications this happens with.

EDIT: Oops, I forgot to tell you to try forcing all CPUs online using Android tuner. In Android Tuner go to settings, active tweaks, boot settings, choose Force all CPUs online, select init.d script, and then reboot your phone.
[HTC Sensation] allenfoxtc:
For Edit: You need be more specific : Which settings not work, kernel or system-performance ?

Take a look at init.d script. You used the same number for readahead.

Also one question, does it change a lot using 32bits color depth? And what is the usb otg option in kernel tuner for?

Enviado desde mi Sensation usando Tapatalk 2
[HTC Sensation] Sultanxda:
*facepalm* I'm stupid, however, that doesn't affect actual usage, they're just the instructions.

As for 32-bit color depth, I believe the deepest color depth I saw in the kernel's configuration was 24-bit, but I might be wrong; I look into that to see if setting 32-bit in Kernel Tuner makes a difference. As for the USB OTG option in Kernel Tuner, I have no idea :eek:
[HTC Sensation] Sultanxda:
r20.5

I've uploaded r20.5 with the bootloop fix. The bootloops were being caused by the boost and zipalign binary files in /system/bin

In r20.5 I've removed those two binary files and all versions (even the no aroma version) will automatically delete those two binary files for you, so you won't get any more bootloops.

EDIT: Nevermind, I tested it once and it worked but now I tested it again and it isn't working :mad:

EDIT2: Nevermind, I tested it 5 times and it's working... I am so confused :confused: I'll leave r20.5 up for now. Please tell me if you still encounter bootloops.
[HTC Sensation] CRACING:
No, I'm S-OFF :p

I don't think it only happens when rebooting from power menu. It also happens on power on (after power off) and also rebooting from recovery.

Ok no problem, I will try the r20.5 and let you know how it goes. :)

Thanks...

[HTC Sensation] Sultanxda:
I've attached a test at the bottom of this post; please install it and tell me whether or not the bootloops persist.

If you get constant bootloops, simply remove the battery and reinsert then power on. Because the boot loop issue doesn't seems to occur on power on.

Sorry but still has same issue. r20.5 as well as r20.5 test 1.

Another thing I have noticed is, normally there will be vibration upon boot up but the kernels that have boot loop issues, won't vibrate upon boot up. Also you were right, boot loop issue occurs upon rebooting only. I think there is a problem with turning off system and turning on but I have zero knowledge in android kernel and functions.

Do a powerful kernel reset then install the aroma version again and in the aroma set your max CPU frequency to 972MHz. Make sure that if you have a CPU control application installed that you set the max freq to 972MHz. If your phone boots up with this then I know what's wrong.

Hi android1234567,

I switched to your kernel 2 weeks ago when I started using albinomans CM10.1 build...

Last version is stable again.

The battery life is great but I have one question regarding that mpdecission-bug and the min voltage of 800mV... I'm using -75 uv but it doesnt stick below 594MhZ...

I was on Viper 1.6.x before with bricked 1.4 and it was quite stable even with -100mV. Any chance for a fix?
[HTC Sensation] Rajan_96:
There is no fix for that, undervolting will vary between ROMs and Kernels, you just have to deal with it.
[HTC Sensation] .hEiMDaLL.:
Yeah, I know that uv varies with every rom and kernel.

Maybe I should change my question a little... What kind of bug is/was that? I'm just curious and as I mentioned before: badass with 750mV instead of 800mV was perfectly stable here before.

The 2nd CPU core would be forced offline indefinitely (until rebooting) if the 192MHz frequency was set to a voltage lower than 800mV and if your min freq was set to 192MHz.
