[Thunderbolt Android Development] froader:
Running BAMF 1.2 with the 1.9 kernel and I have noticed the best battery improvement thus far. Much better than 1.8.

I would like some clarification, just to make sure. The kernel is already designed to run at 245 with the screen off. I have been using Setcpu profile for screen off 245/245 ondemand. Is this profile basically duplicating what this kernel already does? If so I am just going to disable that profile.

Thanks for all the great work!

Noob here. Wondering how to get back to stock kernel once I flash this kernel.

Thanks for help guys.
[Thunderbolt Android Development] droidboy850:
Flashed this kernel. Went into rom manager to try to restore to a backup and now my rom manager won't let me go into clockwork recovery. What gives?
[Thunderbolt Android Development] sdorn77:
Either use a backup or download the stock kernel from ROM Manager.
[Thunderbolt Android Development] droidboy850:
Cool. I downloaded this kernel through rom manager and installed it on my rooted phone and it took away my root. Now I have to root all over. WTF!!!!
[Thunderbolt Android Development] sdorn77:
Try downloading the superuser app for sense in this forum and see if that restores your root.

Having the same problem. Not sure if it's the kernel or the latest rom because I'm not using the das kernel but I an using the 1.3 rom. My circle battery widget doesn't change either so it's not just the icon in the notification bar.
[Thunderbolt Android Development] droidboy850:
Didn't work. I'm so MAD.
[Thunderbolt Android Development] sdorn77:
Can you reboot into recovery and restore a backup? Even if ROM Manager wont reboot you into recovery you should be able to use adb to reboot into recovery or access recovery through fastboot.
[Thunderbolt Android Development] droidboy850:
Seems to be working... now how do I get the 1.9 kernel off and the stock one back on? Or will the 1.9 automatically be off since I'm restoring a backup?
[Thunderbolt Android Development] sdorn77:
It should be off after you restore the backup.
[Thunderbolt Android Development] droidboy850:
im on virus rom. Should i try flashing the kernel again?
[Thunderbolt Android Development] droidboy850:

was using the 1.9 kernel, and just as a FYI, i found something on the internet about

disabling the 4g to save battery. im not in s 4g area, so why not?

i tried it, and couldnt make calls, recieve calls, nada.

had to restore a backup previous to installing 1.9 to get calls back.

however... wow.. my battery life is WAY better.

There is an app in the market made by jcase called 4g lte settings. It will turn your radio for 4g on and off with only one step...
[Thunderbolt Android Development] droidboy850:
Thanks.

It says Battery_is_life and says adrnalyne.

Few questions. So if the kernel gets an update. I just go in and download it and then I can flash over this current version without removing it first? Is there an option to remove the kernel in rom manager? Also my quadrant score running Virus and this kernel has been varying between 1600-1900 when I run the quadrant. Is that about right? Thought i'd be seeing up in the 2000+ range.
[Thunderbolt Android Development] failsaf3:
Should be OK to flash over with future updates unless Adrynalyne instructs otherwise. I'm not running Virus so I'm not sure on the quadrant in regards to that ROM.
[Thunderbolt Android Development] droidboy850:
What if I want to try a different kernel? Can I just flash over this one?
[Thunderbolt Android Development] Gunthermic:
That Kernel breaks Wi-fi and such. Not a good one to recommend. IMO.

However i get what your meaning. So when gettting ROM's, you should ask the DEV for a Kernel only as well.. Without that,you must wipe and re-flash the ROM again?
[Thunderbolt Android Development] ddgarcia05:
I flashed the kernel but when I open setcpu it only shows the highest setting as 1024. I can't scale it up. What gives?

Quadrant score of 1189

Im on version 1 or 1.1 of the das bamf rom and this is the first kernel I installed besides the one that was first required when flashing this ROM.
[Thunderbolt Android Development] want a droid:
Could someone post up some tips on setcpu, governors/profiles, but mostly on "on demand" and "smartass" in what they are, what they do, and when to use them?

If not here in a pm?

Thanks guys
[Thunderbolt Android Development] rayzryd266:
I second that request - please
[Thunderbolt Android Development] failsaf3:
It's been stated in the OP and several times throughout the thread that this is not an OC kernel.
[Thunderbolt Android Development] htowngator:
So can you install this with just a simple rooted phone or do you need a custom rom first?
[Thunderbolt Android Development] CBMC:
Should be fine installing through clockwork with a stock rom.
[Thunderbolt Android Development] ddgarcia05:
Yes, but does this apply if you flash a custom kernel from rom manager? If not, that would be my point. I flashed a custom kernel and i got nothing.
[Thunderbolt Android Development] pinhead875:
This thread is for Adrynalyne's 1.9 kernel. 1.9 is the version number of his kernel, IT IS NOT OVERCLOCKED. It doesn't matter if you flash this custom kernel in Rom Manager, it's not overclocked. It has other modifications from the stock kernel that make it better than stock. But it is NOT overclocked. If you want an overclocked kernel, find one on another thread, or on Rom Manager (rom manager>download rom>MrBobrowitz>das_bamf kernel 1.2ghz OC).

Hope this helps. :)
[Thunderbolt Android Development] corenojoe:
Kernels are for more than just overclocking.
[Thunderbolt Android Development] JFMFT:
This is a fantastic kernel! Hats off to the dev on this one.

Sorry to the folks who want overclocking. If you read carefully, you'll see it says there are no oc slots (meaning no overclocking). I'm sure there will be TONS more Kernels coming out in the next few weeks and months... so hold tight, most of them will have overclocking.

My battery life, by the way, is a bit better with this kernel after about half a day of use. I'm at 40% when normally by this time of day I'm at 10-20%.

Now I'm just as happy with my Thunderbolt as I am my Xoom. Thanks Adrynalyne for your hard work!
[Thunderbolt Android Development] ryanstfl:
sexy! that is all.
[Thunderbolt Android Development] jayhammy:
I LOVE this kernel. Definite speed improvements,etc. The only issue I see is that the GPS doesn't lock on for a VERY long time--like 10-15 minutes.
[Thunderbolt Android Development] adrynalyne:
That won't be related to the kernel, I'm afraid.
[Thunderbolt Android Development] v4npro:
Nevermind.
[Thunderbolt Android Development] jayhammy:
Interesting. Well, it only happened on the 1.9 kernel. The 1.8 worked fine. And now the 2.0 kernel works fine. I guess it's moot now because it's fine with 2.0!!
[Thunderbolt Android Development] :
Just to clarify since the last one didn't say this.

It's supposed to say

Installed 2.0 over 1.9, in setcpu I dont have a setting for smartass now. Just leave on ondemand?

setcpu is a program...smartass is one of the options under cpu govener... some people like ondemand,well there is 7 options,one other being smartass...hope that helps...
[Thunderbolt Android Development] RafficaX:
so with using this kernel, do we need setcpu even? seems like smartass handles it all and removes the need for setcpu if you dont use any other profiles besides screen off.
[Thunderbolt Android Development] jlevy73:
Correct, it's actually preferred not to use setcpu with smartass (if it's set as the default) as the two can conflict with one another.
[Thunderbolt Android Development] :
Does smart ass save battery when the screen is off?

Can someone also confirm what its supposed to say for kernel version under the software information settings. Please.

[Thunderbolt Android Development] feedhead:
From adrynalyne in BAMF thread ...

"Some notes about smartass governor:

Phone sleeps at 245mhz min/max.

On wakeup, ramps to 576mhz.

At 60% cpu load ramps to full speed.

At 30% cpu load, ramps down.

Setcpu profiles can and will conflict. i recommend using a different governor if using setcpu.'
[Thunderbolt Android Development] adrynalyne:
Keep in mind those are for a different kernel but that's the general idea.
[Thunderbolt Android Development] rayzryd266:
Just to clarify - you recommend deleting setcpu if it's already installed while using this kernel, so there is no conflict - right?
[Thunderbolt Android Development] Ovrclck:
Thanks man!

Is 2.0 included with 1.3.2? I'm sure I'm going to get this answer in like 20 seconds on IRC but still... HOW DO YOU LIKE MY SIGNATURE?! :D
[Thunderbolt Android Development] droidboy850:
Wow idk if my phone is frozen or what. I'm runing Virus ROM and the 2.0 Kernel and today I went from 8AM-Midnight with heavy texting/you tube watching/tethering/ and an hour of phone calls. It seemed like the battery would just not drop down. I could watch 15 minutes on youtube without the battery dropping 1%.
[Thunderbolt Android Development] CBMC:
Are you using the extended battery? I have noticed, that the meter doesn't drop much until I do a reset. Then it catches up with my battery. Might very well have to do with the phone not having "learned" the battery yet. I have read severel people with this problem (especially with the extended battery).	Someone said that it calibrated after a few charges. I got my extended battery the same time as these kernels started coming out, am willing to bet that it is something with the battery not being calibrated and not the kernel. I will post back in a few days if the calibration gets better.
[Thunderbolt Android Development] adrynalyne:
No.

I recommend not using profiles with it.
[Thunderbolt Android Development] adrynalyne:
bamf has its own kernel.

[Thunderbolt Android Development] want a droid:
Thanks adrynalyne
[Thunderbolt Android Development] blaine07:
I really almost feel like 1.9 was a little smoother. I'd say battery was almost a little better on 1.9 too but that's not exactly fair to make judgement on without a few days use. I do know that when I woke up this morning my phone was crawling & I had to restart it. I'm afraid if I'd had alarm set it might not have went off.

Very anxious to see where this kernel goes, because its certainly on the right path!

Thanks for the hard work, sincerely!

Not sure what happened last night but I turned my phone off while getting ready for bed and then back on when I got in bed, but out of nowhere i was stuck in a bootloop.

Ended up in cwm, tried rebooting from there and after it showed htc screen it would flash a blue screen then go black.

Eventually flashed my stock rom backup which was annoying.

Any one have any idea what happened?

It does but I do not use stock MMS, I use handcent and it work fine on everything else.

I think 1.9 had better battery life than 2.0 by 15-20%
[Thunderbolt Android Development] catalyst11:
I thought I was getting better battery life on 1.9 as well. Another thing I noticed is that on SetCPU, it doesn't go below 768mhz when I just let it sit there even though my Min is set to 245mhz and on smartass. Could this by why battery life is worse?

Any updates coming soon? I liked 1.9 due to battery life. 2.0 runs perfectly but I think the battery is better on the other one.

Any other kernels with good battery life? I care more about battery life than overclocking

Hmm, had to restore SetCPU for allowing to change the governor, but it works now, thanks.
[Thunderbolt Android Development] shaddix2:
is it necessary to use setcpu to set the governor to smartass or does this kernel use it automatically? I don't particular want to install setcpu as I read it doesn't really do anything if you have a good kernel.
[Thunderbolt Android Development] spimonkey34:
Looks like it is set to smartass by default so setcpu would only be necessary to change governors.
[Thunderbolt Android Development] spursrchamps2007:
can someone explain the difference between ondemand (which is what i used on my OG droid) and smartass. Now i did find a post on it in the xda forums

smartass (Best explanation i've found paraphrases to: based on interactive, but better.)

nteractive

The 'interactive' governor has a different approach. Instead of sampling the cpu

at a specified rate, the governor will scale the cpu frequency up when coming

out of idle. When the cpu comes out of idle, a timer is configured to fire

within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer

fires then we assume the cpu is underpowered and ramp to MAX speed.

If the cpu was not 100% busy, then the governor evaluates the cpu load over the last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down to

So is it somewhat like ondemand just better it sounds.
[Thunderbolt Android Development] nosympathy:
well anyone who tells you setcpu doesn't do anything is full of crap.

you do need setcpu to change the governor, and then you can set profiles and so forth. I always set it to only allow my processor to run at 245Mhz when the screen is off, this saves insane amount of battery.

also when we finally have a kernal you can overclock with, you will need setcpu to do so.
[Thunderbolt Android Development] davezaff:
did you flash through clockwork and select the wipe check box?
[Thunderbolt Android Development] Nikolai2.1:
So I take it over clocking won't destroy battery seeing as it's under volted?
[Thunderbolt Android Development] nosympathy:
this kernal doesn't allow you to overclock.

Install went perfect on your 1.2 ROM, AWESOOOOOMMMEEE!
[Thunderbolt Android Development] Nikolai2.1:
just kidding i saw that now lol sorry guys
[Thunderbolt Android Development] shaddix2:
The reason given was that a good kernel already downclocks the cpu when the screen is off. Could be wrong though as I don't even remember where/when I read it.

Before this kernel I never got above 1900 from quadrant.

FYI: The first quadrant score after flashing this kernel showed 2005. The next run showed 2178 and the third run was 2145. using the default governor (not sure what it i set to).
