battery life is one of the key things... in this respect... you get better battery life... mainly because when your freq changes... your volts being pulled is lower.... so everything you do, is running at the same speed... but taking less battery... then you run into other schedulers using them can speed up the processing of tasks and such... so with that short and incomplete explanation.... you get the same or better performance from a so called "stock" kernel, with better battery life... which in phone terms is a huge piece of the pie... next being performance in requested to using it as a smartphone for games and development...
[EVO 4G Android Development] thedudejdog:
yes... that's pretty much what i'm looking for, exactly. now i'll have to test this a few hours then write a script to echo after each boot
[EVO 4G Android Development] BlueHarford:
oooo, sooo loooooooowwwww.. sooo risky... hope it boots LOL.

mine wont boot below 925
[EVO 4G Android Development] cheflarry:
My phone went haywire with 1.0.1. Could not even flash back 1.0.0 and run correctly. Had to nandroid back.
[EVO 4G Android Development] thedudejdog:
I had to bump it up to 825. sometimes takes a long-press on the power button to wake it up. haha

I don't plan on making it permanent that low, but it's fun to think about.
[EVO 4G Android Development] BlueHarford:
what rom are you using?
[EVO 4G Android Development] thedudejdog:
cm7 nightly 30
[EVO 4G Android Development] teomorell:
I just tried 1.0.1 on CM7 RC2 and the screen sensitivity went very erratic. Almost impossible to use Swype. I had to rollback to my backup. I'm using 1.0.0 now.
[EVO 4G Android Development] Seagrizzly:
For some odd reason I am not finding the havs file in the sys/devices/... folder. Why would this be?
[EVO 4G Android Development] beastmods:
anyone running 1.0.1 without any issues?

wondering if i should flash?

people with issues what hardware evo are you running?
[EVO 4G Android Development] thedudejdog:
to quote the post someone quoted from ziggy's site...

Taken From Ziggys site:

sysfs VDD Interface Usage:
Hybrid Adaptive Voltage Scaling (HAVS):”<freq> <min_vdd> <max_vdd>”
echo “128000 850 900″ > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels_havs
[EVO 4G Android Development] swaze:
Yep zero issues.

Sent from my HTC Evo running CM7
[EVO 4G Android Development] Seagrizzly:
I figured it out, I had to be booted into the rom to change the level's but every time I boot in it doesn't stay up long enough for me to change them. Is there a way to write a script to do this on boot?
[EVO 4G Android Development] thedudejdog:
did you set them too low? lol just reflash the kernel. there are scripts to do it I'm going to get one set up tomorrow if I have time.
[EVO 4G Android Development] blackroseMD1:
No issues here on 0003 hardware.
[EVO 4G Android Development] mkc90:
I dnt understand the kernels ?? Can somebody tell me which kernal I can flash with the royal liquid rom?
[EVO 4G Android Development] Circaflex:
any chance we see that no havs kernel before tomorrow?
[EVO 4G Android Development] LifeInTheGrey:
You don't understand the kernels because they mainly speak in code.

You can try flashing any of the kernels, but I recommend 1.0.1 cfs. If you get screen tearing, or experience sudden locust swarms, the kernels may not work with that rom.

I have spoken.
[EVO 4G Android Development] BlueHarford:
Lol
[EVO 4G Android Development] adma84:
will you guys be releasing a froyo build for these latest goodies? I had to leave CM7 because of GPS
[EVO 4G Android Development] twiz0r:
I don't think they are

swyped from my cyanogenized and gingerbreaded EVO
[EVO 4G Android Development] adma84:
bummer, I am just going to hold tight until GPS is fixed I guess.
[EVO 4G Android Development] xjackofall:
Have you done the ## fix in a sense rom? I had issues with GPS as well but that fixed them right away.

TeamWin's innovation replaced my laptop with this EVO
[EVO 4G Android Development] Seagrizzly:
If you get a chance hit me up with the script that you end up making, I can't get it to boot stock most of the time, so I can't adjust them because the phone doesn't stay up long enough for me to type in the commands.
[EVO 4G Android Development] drdrewdown:
dont feed the troll bro
[EVO 4G Android Development] adma84:
Wait. I am a troll for just asking about a CM6.1.2 kernel???
[EVO 4G Android Development] adma84:
And I did try it but it doesn't seem to stick with my 003 EVO; so I am just going to wait it out at this point, thanks though
[EVO 4G Android Development] luisrcastillo:
That's a Froyo ROM so you need to flash a Froyo kernel

We are not building Froyo kernels anymore as all AOSP ROMs have moved to Gingerbread
[EVO 4G Android Development] adma84:
thanks for the heads up
[EVO 4G Android Development] bbedward:
Unofficial Builds:

CFS GB noHAVS: http://downloads.zen-kernel.org/zendroid/SZ-1.0.1-UnOfficial-SVS-signed.zip

CFS FROYO: http://downloads.zen-kernel.org/zendroid/SZ-1.0.1-UnOfficial-Froyo-signed.zip
[EVO 4G Android Development] fixxxer2008:
im sorta confused, why are there two different threads for this kernel?
[EVO 4G Android Development] bbedward:
One of them is for unoffificial SBC-Free builds
[EVO 4G Android Development] fixxxer2008:
so this thread has sbc built in?
[EVO 4G Android Development] bbedward:
Yes, we stopped doing non-sbc builds a few releases back.
[EVO 4G Android Development] fixxxer2008:
whys that if i may ask?
[EVO 4G Android Development] itlnstln:
For FroYo, BCBlend (v7 SBC) is probably the best available kernel. Anything 2.35 and up is GB-centric and may not be totally compatible with FroYo (Bluetooth is a good example).
[EVO 4G Android Development] mwielgosz:
There was simply too many builds to have to look after. To make the load easier, they stopped making noSBC versions because there wasn't a large userbase in comparison to the SBC version. Now I maintain the noSBC, which I need to update tonight
[EVO 4G Android Development] bbedward:
In the case of MIUI, Anything above 2.6.35 caused bluetooth issues. In the case of CM6 and other AOSP roms that were froyo-based, the only issues on GB kernels that i'm aware of are wifi and the mass storage driver (which we have a Kconfig option for -- CONFIG_GINERBREAD -- on our git) - so the 2.6.38 on the previous page should be fine for froyo. But can't say how good or bad it will be as I havent tested it, but it should be equal to the normal 1.0.1
[EVO 4G Android Development] fixxxer2008:
yeah im not a fan of sbc, even though the battery does drop quicker without it. i did notice 1.0.1 is alot slower than 1.0.0 is. it's like night and day on my evo.
[EVO 4G Android Development] locozildjiangodx:
1.0.1 CFS makes my phone restart randomly... 1.0 CFS was amazing...gonna flash 1.0.1 BFS to see what happens...

EDIT: BFS Works fine but is noticeably more choppy. going back to 1.0
[EVO 4G Android Development] cjh6386:
he's calling you a troll because this kernel has never been developed for sense roms...
[EVO 4G Android Development] fixxxer2008:
same here, 1.0 is amazing.
[EVO 4G Android Development] Smoke314:
I'd just like to say the svs version of 1.0.1 cfs is working great no reboots or FCs. Everything works, it was posted a page or two back.
[EVO 4G Android Development] bbedward:
The reason for the random reboots and slowness on *some* phones is a decrease in the starting voltage from 925 to 900mV, at least that's what I believe, there could be another cause for the issue. I raised the voltage back up to 925.

Or an error with the build bot, The versions I built for myself and others seems to have no issues.
[EVO 4G Android Development] beastmods:
quick link?
[EVO 4G Android Development] aimbdd:
1.01 is running great here. so far
[EVO 4G Android Development] bbedward:
There's no new release yet, it's just in git.

Can't say for sure thats the random reboot cause, but it's most likely. There's not much pressing in the update from 1.0 to 1.0.1 anyway unless you had issues with SBC (most people didnt seem to have issues on 1.0)
[EVO 4G Android Development] drdrewdown:
its actually b/c the workaround that fella suggested actually works, but the individual he replied to is unwilling to accept it.

its not important anyhow. cheers
[EVO 4G Android Development] jtadeo:
anyone having issues with turning off wifmax on cm7rc3?

wimax just gets stuck on "turning off"
[EVO 4G Android Development] Big-O-Devil:
Up,up, and away super EVO... great work...
[EVO 4G Android Development] adma84:
And I thought we had moved past our differences. I have tried it, it just doesn't stick for me. I want it to work and I am really, really glad it works for you. I just really need GPS and have to pursue other options in the meantime...I really wasn't trying to raise any old issues, I was just asking if we were going to have Froyo builds moving forward. I apologize if that request somehow seemed like trolling. :confused:

Thank SZ team for your work, I get crazy battery life on the 0.1.2 SBC kernel
[EVO 4G Android Development] bbedward:
My GPS is hit or miss for me after trying the fix twice, so I don't blame you.
[EVO 4G Android Development] timothydonohue:
maybe i understand things wrong here, but this kernel is actually 2.6.37.2, not 2.6.38.2, right? i only read the last 50 posts, but checking the site, this seems to be correct, making the thread title a little misleading.

just checking, bc cm7 rc3 is 2.6.37.4

i'd be willing to bump up, but backwards may cause problems. i've already tried flashing this over this rom, and it seemed to cause a few issues. of course, naturally i flashed about 5 things at once, lol, so i can't say for sure....
[EVO 4G Android Development] bbedward:
No it's actually 2.6.38.2, the updater-zip hasnt been updated so when you flash it it will say 2.6.37-ck or something like that - but check the git it's actually 2.6.38 ;)
[EVO 4G Android Development] rockenrooster:
1.0.1 is working great so far, but for some reason when my charge says 100% AND I am plugged in AC power, my CPU gets pegged at 100% CPU usage and phone gets really slow. Other than that its fantastic. Any thoughts?

cm7 rc3

SZ 1.0.1 Cfs GB
[EVO 4G Android Development] soundwavedj:
+1 on extreme sluggish behavior at full charge. Only while plugged in tho
[EVO 4G Android Development] BlueHarford:
YEA well i cant even run 1.0.1 becuase of random reboots :-p... get in line!!!! ;-) jk

We're hammering brandon... best thing to do is send a logcat to issues.savaged-zen.org
[EVO 4G Android Development] wrich73:
For me using SetCPU profiles fixes this..... I am using a "charging" profile 1113/245 with interactive scaling and I am not encountering any sluggishness.

I use smartass 998/245 normally with no screen-off profile.
[EVO 4G Android Development] Lento10:
The only thing I noticed with 1.0.1, it bootloop on the splash screen, It vibrates twice rather than once. The screen looses sensitivity while is charging. Everything else works well,
[EVO 4G Android Development] LifeInTheGrey:
I wanted to check this thread to see if anyone had experienced the same problem before submitting it as a bug ...

Has anyone experienced high sensor usage? My battery was draining oddly (still fantastic, like 30 hours, but down from normal and dropping in odd segments), and I checked sensor usage in Spare Parts and it had really high consumption by both Android System (about 75%) and Dialer (100%). Just wanted to see if anyone else experienced this on 1.0.1 CFS, because I'm checking my system settings and apps as well.
[EVO 4G Android Development] drdrewdown:
1.0.1 is working fine for me. can't say any of what you mention is occuring for me.
[EVO 4G Android Development] ro_bro:
I'm on the Deck RC6 ROM (2.3) and I'm seeing high sensor usage on my camera, like 60% when it's off. I'm also seeing 100% partial wakelock on Google Services I'm going to flash back 1.0 to CFS to see if that resolves it.

I might go back to Tiamat 3.3.3 if that doesn't work out.
[EVO 4G Android Development] drdrewdown:
chances are the kernel will have ZERO effect on your issues.. Go.Od luck tho
[EVO 4G Android Development] BlueHarford:
If you had issues

Re-download from the mirror!!!

I did some inspecting with Chris, our buildbot was stuck 4 commits behind, so leave it to say... things wernt perfect in the last build... my random reboots have stopped.

If you had any issues, please re-download from the mirrors as they have been updated with the latest commits, and re-flash... If you still have problems please post logcat in a issue at issues.savaged-zen.org... if there is already an issue open on your problem plesae just star it rather then creating a duplicate issue.
[EVO 4G Android Development] ro_bro:
The weird thing is that other users of Deck are not experiencing the same issue and getting great battery life, so I just deduced there must be something w/ the kernels.
[EVO 4G Android Development] drdrewdown:
often times this is the case. however check what the guy above you posted. maybe it'll help!
[EVO 4G Android Development] ro_bro:
Thanks, will try.
[EVO 4G Android Development] LifeInTheGrey:
Do what I normally do to check if it is rom-based or kernel-based ... reflash the rom, which will install the stock rom kernel. Let it run for a few hours and see if you experience the same issues. I'm rocking the SZ rom, so the stock kernel is the same, but I'm going to try the new 1.0.1 and see if that fixes it. If not, I will try flashing CM.

In truth, its not a huge impact on battery, but it is a slight drop and all bugs must be squashed! If it turns out after testing that it appears to be kernel-based, I shall formally submit it.
[EVO 4G Android Development] BlueHarford:
If its ROM based please submit it too, as we're trying to knock out those bugs too!! :D
[EVO 4G Android Development] LifeInTheGrey:
Haha of course, I was referred to the gentlemen who was using a non-SZ rom. I suppose I can try flashing a non-SZ kernel (heaven forbid) over the SZ rom and see if I experience the same issues. It seems wrong, though.

Edit: I flashed the new 1.0.1 CFS about a half hour ago, and sensor usage has gone way down. I'll continue to monitor it, but so far it looks good.
[EVO 4G Android Development] tubazeppelin:
*edited for stupidity*
[EVO 4G Android Development] drdrewdown:
your question is worded SO weird.

where else are you downloading from if its not the mirror?
[EVO 4G Android Development] LifeInTheGrey:
It could actually have been a number of things. 0.1.2 was still running on the .37 kernel, and since 1.0.0 runs on the .38 kernel, some of the permissions may have been disturbed. Whenever I flash a new kernel of any type, let alone an upgrade in version, I always run Fix Permissions because it just kind of resets the way the applications interact with the system as a whole. Usually any battery drain issues I have evaporate after that, so my advice is to give that a try before resorting to 0.2.1. It was a great kernel, but .38 is pretty sweet. ;)
[EVO 4G Android Development] tubazeppelin:
WOW just realized how dumb that was. I've literally been looking at the same spreadsheet ALL day so no wonder I'm a little spacy.

Anyway of course I downloaded from the mirror (DUR). I'll give 1.0.1 another show after a redownload. OOF I need to go home...
[EVO 4G Android Development] drdrewdown:
hahah glad it wasn't just me :D

i'd say give it a shot for sure!
[EVO 4G Android Development] tubazeppelin:
Well in a more real-question I've read HERE that SBC kernels are teh bad and you shouldn't use them because they'll fry your battery. Wondering if that makes any sense here or have they ironed out all the trickle-charge issues?

Is that article just a red herring and am I missing out on like 3401235123 mFlops because I'm staying away from SBC kernels?
[EVO 4G Android Development] LifeInTheGrey:
Basically, in some of the earliest builds there were reports of a couple batteries frying. It turned out that these were cheap Chinese batteries (not official ones from Sprint) and in the months since the debate was raging, no further reports were made. Conversely, the benefits of MUCH longer battery life and bleeding edge performance have been enjoyed by many many users since this kernel first arrived.

Long story short, the issue was put to rest in the public eye long ago, and many (myself included) swear by SBC now.

I have spoken.
[EVO 4G Android Development] drdrewdown:
its actually a really large debate. you can google it until your sick if you wish.. but please dont start up a new war lol

you can make the choice for yourself after researching what it does & what effect/risks there are.

personally i love the ~10% extra battery life..
[EVO 4G Android Development] fixxxer2008:
liking this kernel soo far. 1.0 is being great for me. ive been off charge since 6pm last night and i still have 70% left. :D
[EVO 4G Android Development] juancaperez2000:

edit: i got bootloops
[EVO 4G Android Development] drdrewdown:
nope, what rom?
[EVO 4G Android Development] jtadeo:
can this happen due to SBC kernels?

http://www.snopes.com/horrors/techno/cellcharge.asp
[EVO 4G Android Development] LifeInTheGrey:
Haha did you read it? I mean... it basically points out the flaws in the story. And notice the lack of mention regarding SBC... REALLY doubting that was the cause.

In short... that can theoretically happen to any phone with any kernel.

I have spoken.
[EVO 4G Android Development] asafegous:
What is the difference besides kernel number? Where van I find the changlog?
[EVO 4G Android Development] BlueHarford:

I have spoken.
[EVO 4G Android Development] BlueHarford:

[EVO 4G Android Development] rebosxl:
Although I don't use this kernel because of the lack of NO HAVS support, to all the ppl talking about SBC kernels TRY IT FOR YOURSELF! I have been using a SBC kernel for month now and letting it charge overnight and my PHONE HAS NOT CAUGHT FIRE! Its not even warm -_-.

[EVO 4G Android Development] krypticide:
Flashed RC4 then 1.0.1 CFS because BFS was giving me periodic lag. Had to battery pull du to being stuck on boot animation, but has been working flawlessly since. Maybe I should have tried CFS a long time ago.

[EVO 4G Android Development] bbedward:
1.0.1 had bfs 370, which was pulled from ck's mirror because of lag bugs and other bugs, so for bfs 1.0.0 is your best bet (or 1.0.2 when it's out)

Even with original salvage kernel 1.6 miui won't connect to hidden networks i tried several times. I'll just flash cm7 build 5 and use no sbc cfs havs version and see if it works

EDIT: i'm trying with stock cm kernel first and then with salvage-zen maybe
[EVO 4G Android Development] andnad:
Been running the cfs havs no sbc froyo with miui on wifi for about two hours, along with some texting and calling and it's still at the 76% where I flashed it at. But I'm having some issues, the wake-up is slow, it won't work with usb connection either, and the screen rotation doesn't work. I know the last one is expected but just wanted to report it is still there.
[EVO 4G Android Development] halorin:
In terms of overall speed and smoothness, I haven't found anything better than 6.1.2 with the Savagezen beta. The CM7 nightlies are coming along, but the scrolling isn't as smooth. I get like 53-54fps with mid 2's stdev with the cm6/savagezen combo.

That and not everything is working 100% with the GB roms just yet.
