3.8b3 does indeed not feel so smooth while sliding up and down in tapatalk or left right in tw launcher. Maybe it is just the "sensitivity" of the touch. But i believe it us just getting used to it thing.

Another observation i want to report is, that 3.7 never used cpu state 300 an 400 MHz. 3.8b3 does use these states.

Had a 100% to 98% battery usage in 4hours. No screen on. WiFi on. Average signal. But it is first cycle.

I'm using Omega 11.1

Thanks for your work.

so this mean you have a better battery life, but also notice a lag with beta3?
[Galaxy S III Android Development] korrel2008:
Sliding with tapatalk was alwys laggy.. My phone lost 12 procent in 7hours when i was asleep wifi always on and had some push for notifications from tapatalk whatsapp gmail and facebook, with lightflow on and led on in settings lightflow for 5min

I feel for myself that everything is fluid :thumbup:

Yes there is lag, but i also feel phone getting hotter when running MaxPayne, it did not get so hot with previous versions

Ok i reverted back to 3.8beta 1....i must admit... Less lag on tapatalk app :confused:

3.8beta4

3.8-beta4

38-beta4 is online:

Fix beta3 lag , adjusting pegasus tweak

AFTR+LPA as default

We can have IDLE or AFTR modes with LPA enabled or disabled. (Obviously it is not possible to have IDLE and AFTR together)

Values:

0: IDLE - clock is gated but power remains (does not eliminate any static power consumption)

1: AFTR - clock is gated, CPU core power removed, cache power remains - this eliminates a great deal of static power consumption - cannot be entered if second core is active

2: IDLE+LPA - IDLE + DEEP IDLE - also some parts of hardware are powered down

3: AFTR+LPA - AFTR + DEEP IDLE removal of cache power - cannot be entered if second core is active

Q. "What are these modes: IDLE, LPA and AFTR?"

A. Between screen off and deep sleep states, there are some idle modes supported by cpuidle driver.

They are IDLE aka Normal Idle, LPA aka Deep Idle and AFTR aka ARM Off Top Running. Race to idle by CPU is implemented for power management.

Q. "What idle modes are recommended for power saving? How do i change it"?

A. Recommended for power saving is to enable AFTR and LPA, ie value 3

Example:

echo "3" > /sys/module/cpuidle/parameters/enable_mask

I feel battery drain is still higher compare to previous version. I hour Maxpayne 90%-69%. Almost 30%. The one with v3.7 was 20-25% after 1 hour. Though still early, I will do more testing and let you know.

Also it runs hotter 41.4 degrees. Previously 38 degress
[Galaxy S III Android Development] harunjo:
beta4 have more agressive pegasusq setting, otherwise beta3 have more relax pegasusq...thats why beta4 is hotter than beta3

Glad to help testing this :) for now new idle state is working great :)

Too soon to check battery life but at least looks well for now :)
[Galaxy S III Android Development] baste07:
I find it hard conparing battery life.. screen usage.... it is what it is largely because of how we use it
[Galaxy S III Android Development] jothi2lingam:
Harunjo in v3.8 so smooth....Will revert to you about battery tommorow...Already in v3.7 got about 30 hours but heavy use in FoxHound rom..Great

Which modem are you using mate in FoxHound?

[Galaxy S III Android Development] samaxen:

[Galaxy S III Android Development] harunjo:
wow, i impressed my self..how about v3.8?
[Galaxy S III Android Development] jothi2lingam:
Yes harunjo me too..When after full charge, no wife & mobile data take some long time to drop battery percentage...But when in 50% its drops quit faster than full charge results..Its normal or any bug...So far my v3.7 results without playing any games...Just mobile data (on & off), camera, browsing ( whatsapp,viber,internet,facebook) phone calls. About 3.8 can let you tomorrrow cos i not yet full charge yet after install v3.8:good:

lol jothi fix your "wife" typo, thanks for info about romow rom.
[Galaxy S III Android Development] jothi2lingam:
Already did that before install 3.7..Nevermine i already did as you said at 3.8..Results tommorow
[Galaxy S III Android Development] harunjo:
so your wife really impact to your battery? seriously?

Impact in which way harunjo...What have to fix now:confused:
[Galaxy S III Android Development] harunjo:
who knows:D..i tought maybe your wife sucks your battery too much :D
[Galaxy S III Android Development] ongchonghian:
harunjo, i had a run with v3.8. I found that my phone is always warm to the touch. Not sure if it's due to AFTR+LPA. Other than the warming effect, didn't notice much difference between v3.7 and 3.8 in terms of usage and battery consumption so far.

It's a little uncomfortable to have that warm feel in your trousers, esp in a tropical country. So its back to v3.7 it is for me ;)
[Galaxy S III Android Development] harunjo:
ong..thanks for report .

fyi v37 is using idle+lpa.

edit: with v3.8 my phone temparature is normal..and drain idle is also good.

i also same like you live in tropical country.

warm phone is bad sign..something wrong with your phone, maybe you can trace your wake locks..
[Galaxy S III Android Development] jothi2lingam:
Hahah..ok I try & see the results in v3.8
[Galaxy S III Android Development] ongchonghian:
i see..hmm...my wakelock stats from betterbattery seems fine to me. The warm phone effect only happens in v3.8; my phone don't warm up too much with v3.7 and v2.6p (yeah, these 2 versions are my fav lol).

Regards,
[Galaxy S III Android Development] harunjo:
ok at least you still have your favorite version Lol.

i am test v38 using idle+lpa here.
[Galaxy S III Android Development] PacketJ:
I'm testing 3.8 and will report back tomorrow
[Galaxy S III Android Development] AndreiLux:
AFTR isn't as useful anymore as it was on the S2 due to the static leakage, here the faster residency and transition times of simple Idle clock gating plus the advantage of not having the cache flushed outweigh any advantage. It does not even enter AFTR due to the multicore system and always having some CPU online, if that description is correct (I wonder who came up with it).
[Galaxy S III Android Development] jothi2lingam:
V3.8 whole night from 11.30 night to 7am battery drops to 5% only with deep sleep (no wifi & data)
[Galaxy S III Android Development] MuertoKo:
Meaning AFTR should be pointless and better using IDLE?

For now at least AFTR works as good as IDLE from user point of view :)

Btw can anybody link me to thar ROM that is using this kernel? The one mentioned some posts ago, can't find it and looks interesting :)
[Galaxy S III Android Development] harunjo:

was running 3.7 for the longest time, just flashed to 3.8 over the weekend..

and this morning tried 3.9b1, somehow 3.9b1 felt smoother for me, more like 3.7. important thing battery life still ok, battery not warm and exfat working!
[Galaxy S III Android Development] samaxen:
Checking 3.9Beta1 so far looks good will report about battery tomorrow. :good:

Trying the the new modem LH1, one thing i have noticed about this modem, the wifi speed is a lot better than DXLG2, reverted back to Wanamlite v2.2 , as the internal2external script doesn't work properly on Foxhound
[Galaxy S III Android Development] harunjo:
actually 3.9b1 is fixed for 38..warm issue.

now time for v39beta2 for my experimental work

Should i wait for the 3.9 or flash the 3.8?? Im using wanamlite v2.2
[Galaxy S III Android Development] samaxen:
You can try v3.7 which in my opinion was the best or 3.9b1 is also very good.

why using aftr+lpa?

thanks for notice korrel..

yes you are correct..thats also my reason moved to idle+lpa..download v39beta1 for idle+lpa

btw thanks for your corection

yes i noticed that..i will research about it later.

i am interested with ROW scheduler

but row have been design for JB i think.

I do not expect any changes at all, to be honest. The change number of the fw is the same as XXBLG8 and XXBLG9.

This commit updates the kernel LZO code to the current upsteam version

Speaking of old "parches" lying about, the below fixes a real problem if

Root task group bandwidth replenishment must service all CPUs, regardless of

where the timer was last started, and regardless of the isolation mechanism,

lest 'Quoth the Raven, "Nevermore"' become rt scheduling policy.

Bro checking 3.9b3. Noticing lags in some games and drastic drops in benchmark. I guess disabling arch power is not advantageous
[Galaxy S III Android Development] harunjo:
nope i think that not because arch power but because i was tweak pegasus to less aggressive..see change log..

did you also had lag experience with beta2?

and also benchmarking is for performance kernel..this kernel objective is for battery performance..

i am still trying this beta3 for about 2 hours..play some game, lag was not noticed in my case..maybe other can share their experience with 39beta3?

thanks for your report samaxen

well let see for the battery performance..
