That happened to me too!! many times on the v17r7 the screen keep off and the leds on :confused: must restart the phone holding power.
[Galaxy S I9000 Android Development] zacharias.maladroit:
thanks for your feedback slyferx !

@all experiencing this issue:

this also happened with Neo 17 r5 ?

if yes - less often ?

what governor did you use ?
[Galaxy S I9000 Android Development] lycan_codex:
Hello Zach,

The recent v17 R7 seems to break the wired headset controls...is there any way to fix that??

I tried v16 too now. wired headset controls doesn't seem to work in that kernel vernel version too.

it works with stock roms.
[Galaxy S I9000 Android Development] zacharias.maladroit:
Hi lycan_codex,

just to make things clear:

with "stock roms" you mean samsung based roms such as Darky ROM ?

or cm7 nightlies with "stock" cm7 kernel ?
[Galaxy S I9000 Android Development] purpleraintoxicity:
I hade it to. A lot. In both r5+r7r7

Happend twice on r5. Lot more on r7. Usually in ondemandx at both
[Galaxy S I9000 Android Development] zacharias.maladroit:
that's really valuable information - thanks !

ok, so it seems there's less benefit in using ondemandX then

I'll see whether I can figure out an alternative
[Galaxy S I9000 Android Development] purpleraintoxicity:
Thanx! Ondemandx is excellent beside that..didn't want to doublepost so edited here:

On r7 got android od up to 70% out of the blew. Ckeaned catch and down to 13%

Now afer reflashing its 7%

My ohone stopped to go2sleep mode all of a sudden.

Again, catch,dalvik, fixed.,.

Two of them came w/out any reason
[Galaxy S I9000 Android Development] .:Crack:.:
Why wouldn't it boot? Oo

Samsung ROM's have the gps.xml in /vendor/etc/ too?

Edit\\ Read tthe thread before posting -.- Thanks for the answer Zach
[Galaxy S I9000 Android Development] krarvind:
you are correct, that was me misunderstanding/reading your question. Booting should be no issue but i can't say if this gps.xml will work in samsung roms as i don't have one.
[Galaxy S I9000 Android Development] slyferx:
yes on both, and i use ondemand governor, bfq/cfq io some UV and no OC.
[Galaxy S I9000 Android Development] mobidzid:
I jumped directly from Neo16, no such issues there. Ondemand only.

Hello zach,

I meant the original stock roms ike jvp , jvq and jvr roms.

Now, i am on MIUI 1.8.26 and use your kernel Neo 17 v7. apart from wired headset controls, everything else seems t work well for me.
[Galaxy S I9000 Android Development] montrealcityboy:
does the gps fix need to be reapplied every time we flash a nightly and/or kernel?
[Galaxy S I9000 Android Development] madd0g:
when flashing nightly
[Galaxy S I9000 Android Development] Kino87:
Uhm, looks like I have a problem with 17r7. With some apps when someone calls me the accept/reject call won't come up (I just have the vibration/sound and the home button won't bring me to the launcher, power button works as it should but locking/unlocking the screen doesn't solve the problem).

It happens every time with Sword Requiem, even if didn't happen in the past (kernel 9r5), and today happened even on the lock screen.

Tomorrow I'll try to flash a newer nightly and flash back NEO 9r5 to be shure it's kernel related
[Galaxy S I9000 Android Development] ShadedCyan:
Flashed NEO 09 redux V5 on Insanity, there seems to be artifacts in my videos and games and shadow around icons on my status bar. Anyone facing similar issues?

Oh, and somehow I can't undervolt with SetCpu anymore.
[Galaxy S I9000 Android Development] Overlord Pain:
I have always got a force close from SetCpu when trying to undervolt. How did you get it to work?
[Galaxy S I9000 Android Development] lycan_codex:
try using voltage control app from the market for UV / OC.
[Galaxy S I9000 Android Development] ShadedCyan:
Using PimpMyCpu works, but it doesn't offer as much features.

Anyone else? Graphical glitches in insanity?
[Galaxy S I9000 Android Development] Funnnny:
Mostly thing for the ROM works fine now, so it the time for some tweaking. It would be great.

As bilboa will stop the development soon, so you should go first or glitch kernel will do it better
[Galaxy S I9000 Android Development] Rezou:
I've just tested quorra r6+ INTERACTIVE, and it's the smoothest governor (and so the kernel too :p) so far.

With ondemand I was used to get ~33fps, and now with interactive I have around 56 fps (OC @ 1.3Ghz).

The phone feels noticeably snappier/faster with this INTERACTIVE quorra r6+ ;).
[Galaxy S I9000 Android Development] TheNikkoMan:
R6+ non-interactive was really laggy in the beginning, but after some hours of standby, it's smooth again :D thanks zach
[Galaxy S I9000 Android Development] bungknees:
thanks for you reply Zach, awesome kernel. everything is working SWEET. I'm gonna take your advice and try interactive for a while and see how that goes.
[Galaxy S I9000 Android Development] ImraanK:
Nope..all apps seem to working Zach..

I flashed back to interactive 6+ before going out( I have them on my SD card :p )...made a few calls.... phone was snappy... locked it and put it away.. needed a number from my phone so took it out, unlocked...lag is back, took a good few seconds to open the contacts app...

I find that sometimes locking and unlocking cures the lag..

Thanks for the awesome kernal btw :)
[Galaxy S I9000 Android Development] zacharias.maladroit:
@all:

lol - you guys are killing me ;)

I thought the kernel was fubared ^^

why didn't anyone mention this problem earlier in this reproducible way (tap tap revenge 4) ? :p

for reference (anyone who is facing similar problems):

this lag was (most) probably caused by the sampling down-factor change in the ondemand governor

I reverted that commit & commented the change out with the sampling rate and now it's back down again at 35000 [was set to 300.000 for more frequent checking]

I tested it with conservative & ondemand governor:

there should be (hopefully) no lags anymore

interactive is a wholly different beast :rolleyes:

thanks !
[Galaxy S I9000 Android Development] zacharias.maladroit:
Changelog:

- fixed short-term & long-term lags with ondemand governor

- no change with interactive

- conservative + conservative; ondemand + conservative governor

edit:

there might still be some small micro-lags but this is currently quite hard to troubleshoot :(

not sure if they will never happen with the other kernels
[Galaxy S I9000 Android Development] ImraanK:
Quick question .. is it fine to adjust the governor via setcpu or pimp?
[Galaxy S I9000 Android Development] zacharias.maladroit:
sure, but it will get overwritten

by the 90screenstate_scaling script

so if you want to change your governor more often

then remove that script from

system/etc/init.d

:)

Hi,

anyone got led notification working with miui rom ?

edit: found that I needed to disable wake up from sms settings to have the led working ^^
[Galaxy S I9000 Android Development] darjan86:
Great kernel Zach I think this is the most promising cm7/miui kernel, but still can't understand how a low-end 2d game like doodle dash lags(hick-ups) A LOT and almost all 3d games are smooth as ice. I've tried both new kernels and the result was same even with 1,3 oc
[Galaxy S I9000 Android Development] thunderteaser:
Zach, congratulations for your efforts! quorra 6+ v2 is simply amazing and it's the first time it finds my mobile network immediately! :)
[Galaxy S I9000 Android Development] fackamato:
Has anyone compared this kernel to the Glitch kernel on CM7?
[Galaxy S I9000 Android Development] pcboyy:
Yes. But the results are vary on each device.. some ppl like Glitch. But i prefer zach's especially interactive kernel :)
[Galaxy S I9000 Android Development] fackamato:
If you're not using OC or UV the results are not going to differ between different devices of the same model. (using the same ROM and settings)

What is better about Zach's?
[Galaxy S I9000 Android Development] vukandric:
I just didn't lost not a single percent of battery after an hour of sleep! Sounds great, will report tomorrow to see how will it go later! Thanks! :)

Edit: I am on newest conservative kernel, without oc/uv (forgot to do that :D)!

Edit2: I did OC to 1.2 and UV! :D where is my brain... lol :)
[Galaxy S I9000 Android Development] zacharias.maladroit:
it's an issue of the game - the sound effects are not optimized

specifically the shooting and other SFX effects,

music is fine

I tweaked the kernel with pretty strict timings and other settings but it still didn't "fix" it / help

try playing it

- with all sounds off (music off, SFX off) [ok]

- only music [ok]

- only SFX [BAD, lags]

so something needs to be optimized in that game, the framework it was built with, etc.

try to contact the author - if you like - whether he can fix that

besides that it's a nice game :)
[Galaxy S I9000 Android Development] darjan86:
I have been playing this game on all other cm7, stock and custom kernels flawlessly, only on your kernel I got that problem :S
[Galaxy S I9000 Android Development] Funnnny:
The Glitch kernel is unstable for me, glitch for neocore test.
[Galaxy S I9000 Android Development] fackamato:
Really? Are you on I9000? Were you using OC/UV? I'm curious as to why it would be unstable. What ROM?

(I'm sure you posted this in the Glitch thread so the author of the kernel knows about the issue)
[Galaxy S I9000 Android Development] JohnstonF:
Tried code name butterfly yesterday...my phone kept freezing and shutting down. With and without OC/UV...

Sent from my GT-I9000 running cm7 nightlies
[Galaxy S I9000 Android Development] zacharias.maladroit:
Neo 17 r8 is available on IRC !

(server on 1st post on 1st page)

go get it while it's still newly hatched out :)

this should hopefully correct some hangs, lockups, instabilities, etc.

I'm getting graphical issues after flashing the kernel. ( I'm on Insanity)

I've attached some screenshots about the issue..
[Galaxy S I9000 Android Development] siky_dude:
Can you point them out..i can't see them.

I'm not familiar with that game....don't know the standard colors.
[Galaxy S I9000 Android Development] ShadedCyan:
I attached a proper image (While using stock kernel)

In the second image you can see some artifacts in the river this happens mostly on black colors.

Another wallpaper, look at sky in the attached picture. I'm not sure how to describe it, the patches there.

The attached pictures AREN'T AS clear as it supposed to be. Wait, the screen capture function sucks
[Galaxy S I9000 Android Development] ShadedCyan:
Here. See if you can make it out
[Galaxy S I9000 Android Development] slyferx:
@zacharias.maladroit that is great news mate, but u will create an stock color for this version too? with the last kernels r5/r7 (stock color) the colors are great for me, but with vc not :( can u make it please?
[Galaxy S I9000 Android Development] mobidzid:
@zacharias.maladroit: is it ok to use 'ondemandb' in screenstate_scaling script for active state?
[Galaxy S I9000 Android Development] DerTeufel1980:
What did you change here? I've seen, the values from UV_MV_table still aren't copied to frequency_voltage_table.

Yes of course. There's no difference between selecting this in an app or a script.

ps: grüsse aus kassel ;)
[Galaxy S I9000 Android Development] moteb:
thanks zach another great work ..:)

regard
[Galaxy S I9000 Android Development] paratox:
thanks for the new testing kernel! :)

+1 on stock color version!

when will we see zach kernels with fugu base? :D

would love to test one!
[Galaxy S I9000 Android Development] zacharias.maladroit:
those graphical issues or "glitches" are caused by voodoo color in combination with low brightness +/- screen filter

I'm still working on this new kernel - the master branch isn't up-to-date yet

so it will probably take a few more days (or hours) until it's ready (with stock colors)

besides that the UV & frequency table doesn't seem to be finished - bear with me here

I'm pretty new to this OC/UV stuff and more and more understanding how it works

but stay assured it'll be fully functional soon

Hi mobidzid,

of course :)

ondemandb was meant to be a substitute for the tweaked ondemand governor

so ondemandb ("battery efficient" - basically it's stock ondemand)

should offer comparable or better battery runtime to cm7 stock kernel

[I read your complaints about worse battery runtime and this should solve those issues]
[Galaxy S I9000 Android Development] zacharias.maladroit:
some test builds might appear in september

but I'd rather fully concentrate on other things right now (study, personal things, etc.)

besides that it needs some heavy testing for that new kernel base

yes - that's right, I'm doing several tests prior to posting the test-builds on IRC

doublepost - sorry !
[Galaxy S I9000 Android Development] lippol94:
To enable ondemandb.. do I need to add this line in the screenstate_scaling script?

AWAKE_GOVERNOR="ondemandb"

??
[Galaxy S I9000 Android Development] siky_dude:
Yes..you do.
[Galaxy S I9000 Android Development] DerTeufel1980:
hi,

what exactly does down_differential do? is this the same like down_threshold?

edit: found it: down_threshold = up_threshold-down_differential ;)

is down_differential tuneable?
[Galaxy S I9000 Android Development] zacharias.maladroit:
it seems to help avoid the frequency jumps during workloads with frequency spikes and thus smoothen the experience

haven't tested the effect on real world practice due to lack of change

give it a try & report :)

is that meant to be serious ?

just google for it and then change the knobs ;)

that's why I added it - so, simple answer: yes ^^

even the kernel documentation is lacking information

I'm not here to fill in all the blanks :(
[Galaxy S I9000 Android Development] siky_dude:
I have a problem...previously flashed fugu 1166 i think and i couldnt instal anything...

Now flashed neo and the problem persists.
[Galaxy S I9000 Android Development] Zatta:
Just flash latest nightly again and you are fine.

Than proceed to fugu 1184 if you dare, its in the stable folder, not in the experimental/ testing.

edit: is this the correct thread for this?

Tapatalked u see
[Galaxy S I9000 Android Development] DerTeufel1980:
alright, as I supposed, it is not tuneable. And it is not tuneable by default, so this is why I was asking, if it was made tuneable by you.
[Galaxy S I9000 Android Development] siky_dude:
Okay...thanks :)

Why didn't i think of that..
[Galaxy S I9000 Android Development] zacharias.maladroit:
it IS made tunable

wade through the settings via console or wait until I'm ready with finishing stuff and posting the source

so you guys could go through the commits then :)

[Galaxy S I9000 Android Development] Kino87:
Coming from neo 9r5 to neo 17 (r5/7/8, it's all the same) I've noticed a pretty big performance (arround 10-20% i'd say, depending on the application) drop in 3d rendering. on NEO 17 is the gpu overclock eneabled? If yes what can be the reason for the performance drop?
[Galaxy S I9000 Android Development] siky_dude:
No performance drop man...you are just holding it wrong :D

If you are using ondemandx, yeah..of course you will see a performance drop.
[Galaxy S I9000 Android Development] burner07:
Hey Zach super release ... can you recommend any good settings for supercharger script beta 1 version?>
[Galaxy S I9000 Android Development] extralife:
Really, that's not true.

... using tapatalk
[Galaxy S I9000 Android Development] Kino87:
There is a performance drop ;) Used ondemand back than and using ondemand right now, same configuration with init scripts and tweaks.. anyway won't get any better changing the govenor/scheduler (tried ondemand, ondemandx, smartass, even performance).

Just FYI with neo 9r5@1500mhz I get ~3300 on Smartbench 2011 for gaming performance, with neo 17r7 ~3000@1500mhz. Same story with every other benchmark (antutu, quadrant, and I've noticed some little performance drop even with relatively simple games as angry birds rio)
[Galaxy S I9000 Android Development] zacharias.maladroit:
actually it should work

currently not enough time to test

Hi PatcheZ,

afaik that was the case in the past (if I remember correctly)

not sure if anything changed meanwhile (did the timer get removed ? - didn't compare the implementations from the beginning with now)

well, some seem to prefer mega1 - other mega2 (if it's still applicable),

so it's about choice whether apps get closed faster or not

for me it's more laggy ;)

well, I could tweak the kernel like there's no tomorrow and you'd get even higher benchmark results but it would be unusable due to stability issues

I'm sure I could also tweak it more & still maintain stability but I'm lacking time to run extensive tests
[Galaxy S I9000 Android Development] kobik77:
Had it too with the latest version.

All defaults, so no UV/OC, ondemand and etc.

It started on incoming mail notification and the LEDS turned on. From there it was exactly as you described.
[Galaxy S I9000 Android Development] siky_dude:
Really, that`s true...ondemandX scales up slower than regular ondemand thus more lagg o_O
[Galaxy S I9000 Android Development] extralife:
r7 & ox wasn't laggy to me

r8 & ox ...hmm, seems different

... using tapatalk
[Galaxy S I9000 Android Development] zacharias.maladroit:
ok, so it's a little less smooth (I observed that too)

but that's to be expected - I lowered the optimization flags to graphite only (prior to that more optimizations)

to increase stability

not sure if those issues some experienced with waking up are caused by UV, other settings

or optimization flags
[Galaxy S I9000 Android Development] kobik77:
Zach, just remember that mobidzid had this problem on the previous version before you did these changes.

That is unless you're referring to changes on earlier versions :)
[Galaxy S I9000 Android Development] Kino87:
I don't really understand much about kernel compilation, flags and so on, but people lamented stability problems with NEO 9r5?

I used it for quite a long time (jumped Neo 15/16, so I used NEO 9r5 from it's born to the release of NEO 17r5) and it was as stable as the newest NEO 17r5/r7 (I didn't test r8 enough, but I guess it's more or less the same: no crash unless overclock over 1,4ghz).

The two kernels had about same overclocking capability (I guess newer kernel are more stable, but to have a rock solid phone I can't go over 1,4ghz with both kernels, with higher frequencies the phone crashes anyway after some time, just some minutes of difference).

Not that great difference as user experience (Neo 9 sometimes seemed slower, sometimes faster.. I guess the kernel by itself was a little bit faster but the governor setup wasn't as aggressive as in newer kernels. The only big difference, as reported before, is with 3d apps that lose about a 10-20%fps depending on the test/situation).

Even battery life was comparable, the newer kernel is better but I guess it's because of the newer optimizations like the screen undervolt and not for the compilation flags.

If my phone was/is stable with more aggressive optimization could it be because of a lucky chip? or maybe who had problem, if anyone had problem, had some bad component in his phone?.

If so

, could it be possible for the final releases (not test ones obviusly) to release an high performance and an high stability version of the same kernel? As I said I don't really know much about compilation even if I've been an Arch Linux user for about 3 years, but I guess you shouldn't change the code at all, just set some parameters differently on the compiler. Is it a lot of work? (Just asking, I don't really know)

To be honest I'd rather push my phone hardware to the limit with an highly optimized kernel that crashes at 1,2ghz than being able to UV/OC like a mad but needing to get to 1,3ghz to have the same performance of the said kernel at stock frequencies (Just to say, I don't expect that any optimization could make for a so big difference in terms of performance, was just an example)
[Galaxy S I9000 Android Development] montrealcityboy:
I am on r8 and when setting governor to performance it gets stuck on 800mhz. I am oc to 1300mhz. Not sure how to reproduce it exaclty but last time it happened was after a reboot. Im back on ondemand and it seems to be working as intended.
[Galaxy S I9000 Android Development] moteb:
small help here..:)

i have neo 17 r8..

How can I make sure that the governor is ondemandb

because it doesn't showed in voltag control & pimp my cpu apps :(

do i have to install any script or something :confused:

again a big thanks to you zach ..
[Galaxy S I9000 Android Development] siky_dude:
Delete data in applications-manage-pimp my cpu.
[Galaxy S I9000 Android Development] moteb:
thanks silky..for your help..:cool:

but still Shows ondemand..not ondemandb..:D

now what..:rolleyes:

btw..it is really great kernel i like it so much..

my rom is miui galnet chameleon r2

my cpu setting like this:

1000 Mhz ===> 1200v

800 Mhz ===> 1125v

400 Mhz ===> 950v

200 Mhz ===> 825v

100 Mhz ===> 825v

never been better stable & smooth

I appreciate your efforts Zach

I wish you the best
[Galaxy S I9000 Android Development] slyferx:
Okey mate we will w8 for the stock colors like ur prev versions :D i loved that :o
[Galaxy S I9000 Android Development] BusterSG:
does ondemandb setup has better battery efficiency than ondemand ?
[Galaxy S I9000 Android Development] mobidzid:
@BusterSG: as you see it is basically the same as 'ondemand' in stock CM7. And yes, it is supposed to be better for battery, but with slightly worse performance.
[Galaxy S I9000 Android Development] dupel:
Time for feedback on r8. So far stable. As battery efficient as r7 (very good).

AnD I would say as smooth - while scrolling in browser can be sometimes a bit jerky (tiny bit), the scrolling in xda app improoved.

All in all satisfying.

What I observed, probably system tweaks script is to blame, since a few versions back I have too much free ram (around 90-100). Which I'd say way too much wasted ram. 40-60 is enough for this phone.
[Galaxy S I9000 Android Development] DerTeufel1980:
tryed again to echo into the file: down_differential, but nothing happend.

I've recognized, that this file is placed under:

/sys/devices/system/cpu/cpufreq/ondemand, but it is not placed under:

/sys/devices/system/cpu/cpu0/cpufreq/ondemand

maybe, this is the problem?

Everything else is working fine. thank you Zach
[Galaxy S I9000 Android Development] BusterSG:
opps "better for battery" sounds sweet but "slightly worse performance" sound so errm.. i will keep to ondemand then
[Galaxy S I9000 Android Development] bexem:
I've only some lag in launcher and/or when I must star any app... This is why I set SavagedZen as CPU Governor (and noop as I/O)... I want battery life...(not uc to 800Mhz) Ok, I can't say nothing about the battery life, but if I can improve...

For the rest, the kernel is awesome!
