[GPL]2.6.29.6 BFS Kernel V6 Update 10/17/10

[Decad3nce]

Its something about the Interactive CPU governor on certain phones. Probably the ones that cant go past 768 for some reason. I set it to performance and on demand it works great but when you dont have setcpu installed or when you do and set the speed but still use the interactive gov, then it starts to lag and eventually freezes to where the phone is unusable and have to pull the battery out.

It may be because the task(waking) is being scheduled prior to the interactive cpu governor being able to ramp up the cpu. Which would also hold true when it comes to cpu intensive tasks.

I'll have conap revert the default state of the interactive governor for the next release. We'll also push a CFS based kernel with all these updated goodies.

CFS + interactive cpu scheduler is absolute sex.

Well put lol. And that sounds good, but either way great job on this both of you! I'm using it with normal settings on demand but everything is still so much smoother.

Though I have to say.. I've patched up the BFS on my heroc branch to .318(and .330 locally) and it seems to be a bit more 'stable' with interactive. I'll have to add in the stuff later for desirec(eris).

There's probably that one small difference that makes everything go wrong

Looks like interactive was fail in jumping from 480 to 768, I had the same problem recently on the heroc BFS builds with interactive cpu governor. It's something that I'm also looking into.

If you can recreate this with is a dmesg output and a logcat, it would be fantastic.

At boot my phone runs normal for a min then starts to lag badly. I switch governor to ondemand then back to interactive and it works beautifully again. Do The same thing if it starts to lag again. For the boost this kernel gives its definitely worth the occasional glitch.

Again, thanks so much, decadence and conap. Decadence, you don't even have an Eris and are doing this for us. You're a great man for that and we all appreciate it more than you can know.

i can get the logcat, how i go about getting the dmesg?

 

[Decad3nce]

i can get the logcat, how i go about getting the dmesg?

adb shell dmesg > dmesg.txt
(after you recreate the problem, if you can manage that before the 'reboot')

 

[grimjeeper]

adb shell dmesg > dmesg.txt
(after you recreate the problem, if you can manage that before the 'reboot')

the dmesg file was to big for the forum i'll see what i can do

i got the logcat while it was being slow but it never rebooted it just righted it self if it's not good i'll get another

Interactive seems to end up going south for me. I switched to on demand and it's working very well.

You should be able to snip a lot of the output. It's likely that only information right near the very end is needed. Decad3nce can clarify how far back is needed...

By the way my Bluetooth stereo headset synced with my phone just fine running this kernel. Watched and listened videos on YouTube for a couple hours last night, all with audio running thru my Bluetooth headset. Also used wifi, AND GPS last night and both seemed to work fine on my and my wife's eris. So far so good.

Every now and then and at boot it super lags, but switching governor back and forth to ondemand and back to interactive always fixes, then its back to glorious speed and smooth usage.
Thanks!

Sorry if I missed the answer to this, or if there is some obvious factor i am missing, but is this usable with 2.1 roms?

If so, does the use of the backport of the bluetooth(from .34), mean that it would alow for voice dialing in 2.1?

Or god forbid reliable BT sync?

Bluetooth works fine.. fully and completely functional for me. Reference my post above. Synced with Bluetooth stereo headset as well as computer, and my wife's Eris for file transferring. All worked beautifully. Used for hours without even a single glitch.. and synced with 3 diff devices with absolutely no problems.

you are on froyo, I asked if the kernel works with 2.1

 

[Decad3nce]

Should work.

Updated the kernel to bfs 318 and changed default governer to OnDemand for those that were having some issues after running it for a while. Updated first post with new link.

 

[Decad3nce]

Might be also good to mention that the update to .318 kills most of the 'lag' with interactive cpu scaling(as long as your scaling_min_freq isn't too low).

It's probably still better to stick with ondemand ftm; there's other bugs that needs squashing.

I love you.
