4.1.8 bfs vs cfs

running Fresh 3.1.0.2, setCPU 998 max 128 min conservative scaling w/ no profiles.

Idle Battery life (screen off) with 4.1.8 bfs was pretty bad, switched to 4.1.8 cfs and seems to be much better.
[EVO 4G Android Development] StormCell:
Warning!

SetCPU almost fragged my EVO! Installed the new Fresh. Rebooted. Installed the new .8 bfs netarchy. Wiped cache and Dalvik both times. Used AmonRA's recovery. Everything was great until I went into setcpu and cranked up the speed just a tad above 115200. FREEZE! REBOOT! It took 3 tries before I could get into setcpu and disable it before the phone froze. Damn, shazam. My EVO shouldn't react so negatively should it? Does setcpu need updating?
[EVO 4G Android Development] infamousjax:
Not even close to bricking. You could just boot right into recovery and flash the ROM again to fix the CPU clock.
[EVO 4G Android Development] PlankLongBeard:
Thought is be post 4000... :) in the thread!

Bfs update¦

It works much better than cfs. I see it as conventional vs aggressive. Bfs seems to be more aggressive in resolving processes as cfs is more casual. The battery life is yet to be determined cause they're all too good to differ.

[EVO 4G Android Development] tatnai:
on demand scales up much more quickly, while conservative takes a little more load (don't know if that is the right terminology) before the cpu scales up. I noticed the difference easily looking at setcpu info and watching the number scale up and down. noticed a definite difference in small amount of lag present with conservative. I use on demand for some profiles in setcpu, and conservative for others, depending on whether the profile is geared towards max battery saving (my low battery profile, for instance) or optimal performance (normal use, charging).

[EVO 4G Android Development] kronik420:
I'm sorry to be such a noob but what is the difference between

- BFS (as of 4.1.7)

- CFQ (as of 4.1.8)

thank you which one is better
[EVO 4G Android Development] StormCell:
Ha. Yeah, I started to hyperventilate a little but I knew what the issue was it was just a matter of getting to it. I have read and read and read until my eyes bled but I don't recall seeing anything about unchecking set at boot. But hey it's great advice!

But why is it some evo's can overclock more than others?

[EVO 4G Android Development] netarchy:
CFQ is completely fair queueing, and is NOT in any of my kernels. What you meant to type there was CFS, completely fair scheduler.

As for the difference, the 2 schedulers have different approaches to queueing/handling tasks set to the cpu. There are enough major differences between the two that I made 2 kernel builds, one for each, so people could decide what works best for them.
[EVO 4G Android Development] emulatorx:
Made it to 16 hours of mild usage ..finally at 2% left..applause!
[EVO 4G Android Development] scottspa74:
@ emulatorx

Man, how the hell do you get these times?!

I tried 4.1.8cfq last night (I been on 4.0 for a while) and got atrocious batt life so far. I was 100% charged at 11am this morning, so I pull it off charger, and by 5:30pm down to 10% . That's with 2.5 hrs no use, and a lot of browsing first 4 hrs. 3g browsing only. What I would consider average usage, for me.

Are you using setCPU, and any particular settings/profiles?

I'm using nets stock 2.2, and (obviously) his kernel.

Thanks. Need better battery.
[EVO 4G Android Development] ZombieReagan:
What is your uptime vs sleep time? That kind of battery life sounds like an app is keeping your phone awake.
[EVO 4G Android Development] Mecha2142:
The latest Fresh-compatible version of the bfs kernel is causing my phone to do some weird things in regards to starting up. Namely, it hangs at the splash screen indefinitely until I do a battery pull; at that point, it starts up like normal. I've rebooted five times so far with the exact same results.
[EVO 4G Android Development] enigmatl:
I love what all the developers are doing with the kernels. But now, the developers are starting to give choices. But, these choices are tough even for non-noobs. I imagine that CFS and BFS are explained SOMEWHERE but I couldn't find it. Now, I didn't spend an hour but I did scan the thread.

So, what is CFS and BFS? What are the implications of chosing one or the other? Thanks in advance to anyone who can provide information.
[EVO 4G Android Development] barnacles10:

BFS

newer version

this kernel doesn't let me connect to my wi-fi as well as not letting me scan for blue tooth devices more then once and twice if I'm lucky beyond that i hit the button scan for devices and never does. Wi-fi same thing i hit connect for wi-fi says connecting then goes back to disconnected once or twice it said getting ip then it went back to disconnected. to see if it was kernel i went back to stock kernel and it scanned blutooth and wi-fi with no problem. Don't know if this is happening to others. :confused::confused::confused::confused::confused: 4.1.7 & 4.1.8

p.s can someone post version 4.0 dont know where to go to find the older kernels.
[EVO 4G Android Development] netarchy:
I'm unable to reproduce this behavior. Which 4.1.8 kernel was this on? the bfs or cfs? Did you wipe cache/dalvik cache?

Are you running a custom rom? If so, which one?

4.0.x kernels are on the first post, under the 4.1.x builds.
[EVO 4G Android Development] cctaylor410:
That's pretty high for awake time. After a full day of use I usually have 6 hours or so. Something is definitely keeping your phone up. I know with my phone it will sometimes get hung up syncing when i first boot up. I then have to manually cancel sync. It was killing my battery and keeping my phone awake. I still cannot figure out why it does that but it doesn't seem effect anything once its canceled. BTW using profiles in setcpu makes a bug difference, mine are all set to conservative. The most important one is probably setting a screen off profile to 245max and min, 128 max min caused problems for me, ie it would only ring once for a call and was slow to wake up.

[EVO 4G Android Development] TorxT3D:
i must be missing something with setcpu.

running the bfs kernel, and bumped setcpu up to 1150 (performance)

and my quad scores are the same as non-oc'd.

linpack also barely break 35

made sure superuser is allowing setcpu

is there something wrong i missing?

i guess its not as simple as sliding the slider up to 1150, must be some other options i need to adjust.

had no lockups or reboots at 1150 and quad reports it being the current speed(under system information stats)
[EVO 4G Android Development] netarchy:
Did you re-detect frequencies with setcpu?

Are you running any profiles with stock settings set? (they will override anything you set for global min/max)
[EVO 4G Android Development] martijua:
On 4.1.8cfs, my setcpu info tab time in state always says null. Cleared cache, dalvik, reflashed...uninstalled/reinstalled.....same result. If i install 4.1.2 setcpu info tab time in state shows time for the different frquencies. Anyone else experience this or have any solutions?

[EVO 4G Android Development] Rippley05:
Using EViO and BFS .8 kernel

Everything seems to function well....just sucks on my battery =\

Maybe I'll try the CFS but it just seems like every 2.2 RoM doesn't offer anything close to 2.1 as far as battery life. It even dropped about 35% overnight with the screen off ... I'm using setcpu but I'm using the profile Calkulin set up for the king kernel...which wasn't really any better on my battery

Not to be rude, but these people showing 24+ hours of battery just aren't using their phones IMO...

[EVO 4G Android Development] freeza:
I decided to try FroYo yesterday and am having regrets all around. Everything about FroYo is just not what I expected. 2.1 seems to just work much better for me. My battery literally drained while it was being charged. WTF? it drained so much that my phone shut off and the charging light was blinking for ten minutes before it would come back on again. How is this possible while being charged? DONT KNOW. NEVER Happened on 2.1 that's for sure. Too bad no devs wanted to stick with 2.1 basically forcing me to upgrade with the times. The phone just feels stuttery, so little that you barely notice it, but i do, especially in comparison to 2.1. example: pulling down the notifications bar, swiping from screen to screen in LauncherPro, swiping in text messages. MMS hasn't been working right since I put FroYo on this phone. Random error messages for both sending and receiving. Market isn't downloading stuff correctly and gets stuck on 100%. What the hell is up with FroYo? Horrible experiences so far.
[EVO 4G Android Development] xHausx:
Sounds like you have a process somewhere hogging your cpu, you may have an app that isn't acting right on it. Froyo for me was a massive improvement over 2.1 as far as how smooth it runs and battery.
[EVO 4G Android Development] freeza:
Trying to narrow it down right now lol. I'm using Fresh 3.1.0.2 so maybe something is amiss with that ROM.
[EVO 4G Android Development] barnacles10:
When something like this comes up, and we have multiple multiple people running this Rom without the problems you described, then it has to be something 3rd party, or user related. 2.2 focuses on speeding things up, and the benchmarks show it. Were you running a modded kernel on 2.1? Are you not now? I have none of the issues described above. Not saying you don't, but I am saying its not froyo.

My battery has dropped 3 percent in the past 3.5 hours almost on kings kernel. That's great battery. I would say try to flash again and careful restoring apps from 2.1 if thats what you're doing.
[EVO 4G Android Development] freeza:
Trust me, I'm not one of those people that likes to report random usage patterns that doesn't happen to most people. Maybe Sprint and the market (looks like the market WAS having an issue) were both having problems coincidentally as I was upgrading to FroYo. I was using netarchy's 3.7.5 kernel with FroYo JIT on Eclair with perfect results. Upgraded to FroYo to try it out and I was charging my phone via the computer, so maybe it wasn't enough to keep up the juice and it completely died. I was on a call while it was charging on the computer. This never happened on 2.1 so, I didn't expect it to on 2.2. Anyway, I am running 4.1.8 and have been since I installed Fresh ROM. Not to say that FroYo is running slow or anything, just small quirks i'm noticing. Maybe it's with all the changes in the kernel. conservative vs ondemand that i'm used to. IDK, but I do notice that the market has been acting funky since yesterday and i've read that Google had a massive outage, so maybe my issue with downloads stalling at 100%, never starting, and being stuck at authorizing has something to do with Google. Also, maybe my MMS issues are on Sprint's end. All I know is, I haven't been able to send or receive one successful MMS since I started. I made sure to wipe at least twice before going to FroYo, and have decided to start over from scratch so there are really no 3rd party Apps to blame at this point. I'll just have to do more research before being one of those FroYo haters for no reason :-P
[EVO 4G Android Development] HondaCop:
+1

I've been running Fresh 3.1.0.2 on Netarchy's 4.1.8 for the past 48 hours @ 1.22Ghz with absolutely NO PROBLEMS! ROM is VERY snappy, no lags whatsoever.

Battery drain is insanely slow and performance/stability is like butter.

My setup is simple thus leaving out too many things which can lead to problems.

NO setCPU

Juice Defender/Ultimate Juice

Overclocking via Ultimate Juice @ 1.22Ghz.

That's about it. Rock solid for 48 hours with HEAVY USE (surfing, installing/uninstalling apps/gaming/you tube). Last night I was able to get about 4 hours of HEAVY use NON-STOP on a full charge before it dropped to 15%. This included playing 1 1/2 full seasons on Baseball Superstars 2010, watched about 5 you tube videos, etc etc.

This is where you can really judge battery life. Yes, it would be easy for me to leave my phone on and idle and get at least 24 hours of battery life, but that's not what I bought this phone for. Like I said, I was at extra work last night and used my phone for 4 straight hours and HEAVY use on 1 full charge. This to me is OUTSTANDING!

For those having problems, I HIGHLY recommend you do a COMPLETE FULL DATA/CACHE/DALVIK WIPE. NO DOUBT ABOUT IT. Do a complete wipe and start from scratch.

BTW, I am NOT heavy on benchmarks because they really don't represent real world usage, but this is what I am currently getting:

Gears: 55FPS

FPS2D: 54 avg...7 stdev

Quadrant: 1507

Neocore: 31.2
[EVO 4G Android Development] barnacles10:
I can tell you this. You might notice a different between those governors. On demand is just that, on demand. It will ram your cpu to max when its called upon at all, where conservative might scale to just 728 when you open an app, or swipe screens. So that might be where your slight stall you've described comes from. Try setting the governor back to on demand if you're not a fan, but the idea is saving that battery. Market has also been having issues, yes.
[EVO 4G Android Development] xHausx:
It might be worth a try to reinstall all the google services, I just had a problem with them a few days ago myself. My market wouldn't install apps, random FCs of google services, phone ran like crap, etc

[EVO 4G Android Development] datajosh:
Just tried this using 4.1.8 BFS and while on the very first jump it didn't respond, it did fine from that point on.
[EVO 4G Android Development] Biofall:
I've been thinking about it, and I think there isn't anything wrong with my battery life. I'm getting the same eight to twelve hours of light use spattered with heavy use that I've gotten on my stock 2.1 the day I got my phone. The only difference now is I torture myself with battery watching. Also I have this damn SetCPU to underclock to save battery life, and I'm sick of that. I'm going to remove all of my setCPU profiles that lower my voltage depending on my battery. Then I'm going to change my governer. I'm on king right now, so there are like ten, but I think I'll keep it on conservative, and if I feel laggy, I'll try interactive. I don't remember the numbers exactly, but I think I get unstable around the 119, so 115 is for me.

With these changes, I guess I should say, my battery life might go down to six hours of medium usage.

[EVO 4G Android Development] Rippley05:
I switched to the CFS kernel and so far it "appears" less laggy... no clue on battery life but it was pretty bad on the BFS kernel ...maybe would have gotten 8 hours with normal use... compared to about 20 with the same usage on my 2.1 rom/kernel setup.

No biggie tho, before that I was using one of the first 4.XXX netarchy kernels and got anywhere from 12-16 hours so I'll go back to that if needed.
