Hey hardcore, what do you think about posting some sort of "roadmap" or "to do list" to prevent people from posting the same questions over and over again. It might keep this thread a bit cleaner if everybody can see, what's planned or not.

Just an idea ...
[Galaxy S I9000 Android Development] KennyLegend:
Very good idea
[Galaxy S I9000 Android Development] gsw5700:
Roadmap

I agree that this would be excellent, on the first page you could list the features/bug fixes included with each release and also any future planned features (with approx month if at all known, no pressure!).

You could also list "pending" requested features so we don't bombard you with repeated questions.

This would make the whole experience much more professional whilst provide excellent information for all users.
[Galaxy S I9000 Android Development] gsw5700:
Thanks for that - useful information

Could you also add the results for the "Semaphore Kernel JVH (CF-Root 3.2 + voodoo sound v9 + OC/UV + BLN)" kernel, that would be interesting...

(See General Section)

EXT2 is not as safe as EXT4 with the mount options HC uses. Speed is gained only by compromising safety so it is not a good option to use the much older EXT2.

hardcore,

Really loving you~~~~

Request for CIFS and color tuning.....

Hope that we can adjust the screen color temperature ourselves

Anyway, Thanks again.

I cannot work with my i9000 without SpeedMod already
[Galaxy S I9000 Android Development] gsw5700:
EXT2 etc

I think I read somewhere that EXT2 reads at about the same speed as EXT4 (using typical android I/O profiles) but EXT2 is twice as fast at writing. Would be great to have a option to convert to EXT4 and EXT2 (Use EXT2 if you are willing to run full fsck if FS crashes). I haven't really got a problem with that, if it means I have to run e2fsck or restore the phone every 6 months but get better performance, then so be it !

Another thought, not sure where the ext4 journals are, but is it possible to place them on faster SSD memory or other location so we have the safety of ext4 without so much of the write overhead???
[Galaxy S I9000 Android Development] elhennig:
IMHO instead of using such an old fs as ext2 it would be much better to start using btrfs, as this is going to be the default fs for linux in the future

Problem with kswapd0 eating up CPU !!!

Does anyone have system panel so they can report the amount of CPU that system process kswapd0 is using. This process on my phone (K15H-T4 on JVO) has currently used > 10 minutes, the next largest CPU consumer is events/o (36secs), the rest are taking a few seconds only.

I currently have 107Mb free RAM so wtf is the VMM doing...????

I have re-flashed K15H-T4 and its the same.

Next step will be to flash CF-root followed by K15-T4.

Any thoughts anyone...???

i want to share mines; (of course its not the most important thing but i dont believe its just useless and unnecessary, it may halp comparing different setting in same conditions)

all are quadrant (avarage of 3 times)and with jvh;

without lagfix / lagfix

cf-root 3.2 1050 / 1600

speedmod 1240 / 1503

fugumod(ext4) 1048 / 1037

semaphore(1200mhz)1211 / 1977

original 1058 / ---

hacks+ext4+stck1011 / 1597

seems like what speedmod does is a big improvement, even without the lagfix and overclock it gives a faster user experience.. but i still could not get used to sharpeness fix (the black texts are so thick) and the lag of beginning of the programs/games sometimes..

[Galaxy S I9000 Android Development] elhennig:
This seems to be a problem with GB. I had the problem, too (on Speedmod k15h, Voodoo kernel, DarkCore 2.6).

I truied to solve it by activating GPS oncew, calibrating the compass und switching GPS off again.After that procedure the compass worked well in different apps.

EDIT: After a while the compass did not work any more. I found that there seems to be a problem with the correct interpretation of the sensor data: Obviously a different axis is used for the compass in Gingerbread compared to Froyo. Strange enough this also happens with the compass in Google maps.

[Galaxy S I9000 Android Development] gsw5700:
I was just a comment about this kernel as the system process kswapd0 was killing my CPU eating up the battery. I have re-flashed the CF-ROOT kernel and used the Galaxy Tuner app to apply the mega RAM script tweaks and now all is well again (as long as bluetooth keeps working!)
[Galaxy S I9000 Android Development] LordVetinari:
I use Watchdog Light. I've had a couple of occurrences where it alerted me that kswapd0 is using more than 36% CPU. I can't recall the thread, but here's the instructions that I sent to a friend:

Above instructions were to prove the presence of the battery drain bug for JVK.

I'm running JVH with K15H-T4, but I experienced it with previous K15H's and CF-Root 3.2 as well.

HTH,

[Galaxy S I9000 Android Development] gsw5700:
kswapd0 eating CPU!

Thanks for that, are you seeing any problems now with kswaps0 eating CPU?

I've moved back to CF-ROOT (on JVO). kswapd0 and other system processes are now taking very little CPU. I did apply Jewe's RAM script which may have helped.

[Galaxy S I9000 Android Development] LordVetinari:
;)

Someone posted the instructions on the [Ramad]'s thread by someone. I emailed it to a friend and as such it was easier to copy and paste my email than to find the original post. You may call me lazy.

I've just re-flashed my image as I broke my phone so badly that it couldn't send/receive SMS'. I've had kswapd0 spike about 5 times since I flashed JVH when it came out.

[Galaxy S I9000 Android Development] gsw5700:
Hi, agreed, but will be intereresting to review how they work. I've reflashed K15H-T4 and have applied Jewe's memory settings via Galaxy Tuner. I've enabled monitoring from system panel so will get back with the findings later today. Looking at composite CPU and RAM over last 20 minutes, phone is ticking along with VERY low CPU and 100Mb free ram! Also, nice to get working bluetooth again..

If you are using setcpu that could cause the issue you were having, its bad enough on a kernel that supports OC but on a kernel that doesn't support OC it will thrash your cpu.

Thanks for the awesome work.

After hesitating to try custom kernels for almost a year, finally I did it and everything went so smooth.

I wonder why I did not do yet. It seems to be in the right hands.

I would definitely donate something for this awesome work, once I get back to earning (have been jobless for almost a year :( ).

For now please accept my sincere thanks.

[Galaxy S I9000 Android Development] Hrithan2020:
Are you able to use Galaxy Tuner. I thought , it was not compatible with the GB kernels? Or is there a fix?
[Galaxy S I9000 Android Development] gsw5700:
You can use GT to make the changes but only for the mameoty settings and default scheduler. Incidentally, the default settings in 2.3.4 (which is really smooth/fast) are:-

swp 60

vcp 100

dec 10

dwc 20

dra 20

dbr 5

fa 10

va 16

ss 24

ha 40

cp 44

ea 48

up_threshold = 50
[Galaxy S I9000 Android Development] LukeSP:
SO, Does the speedmod compatible with 2.3.4 firmware?

@hardcoce

would you advise disabling journaling in this kernel ( of course after conversion to ext4).

Are the returns worth the hassle and risks (I have read, its minimal risk of losing data).
[Galaxy S I9000 Android Development] corgar:
maybe create a list on what left:

tun.ko, cifs support

bln support

other filesystem support

no journaling fs in cache partition to save 4mb space

init script support

tweaks support ( needed? )

color temperature support

maybe other kind of cpu governor type

ipv6

the bold are a must have i guess
[Galaxy S I9000 Android Development] gtda:
i just did a fresh jvp, flashed speedmod k15H-T4

first quadrant was 1300, did a second one 1717, highest ive ever had on my phone

now for all the cool mods to be made and ill be a happy sgs owner :)

thanks again hardcore, still loving ur kernels
[Galaxy S I9000 Android Development] gsw5700:
You can lose data if you pull the battery, but this may only happen a few times a year, well worth the risk if you can have better performance all year round via ext2 or (ext4 with no journalling). as long as we have fsck we can normally fix the issue and you can still restore from the last backup, up to you really, so faster with slight risk, or slower with much less risk. Would be great to have the option...

[Galaxy S I9000 Android Development] andip71:
Very well said!
[Galaxy S I9000 Android Development] zacharias.maladroit:
k,

just let him do his thing then - he'll releases source / patches anyway, I won't bother him anymore

I'd however prefer broken-out patches ;)

@hardcore:

do your magic & take time for your next kernel blockbuster :)
[Galaxy S I9000 Android Development] pennzoilgtr:
ok, this do sounds make sense. but isn't it was design this way where after it was full charge, the phone will be using the power from main until you plug out the charger so as it resume on battery?

i guess its not really a hinderance for some other users

but as comparing to froyo its so much difference.

my brother is using a custom 2.3.3 on his htc HD2 and it don't have such feature, and his phone is running great without a problem. he had his phone plug in as long he is at home.
[Galaxy S I9000 Android Development] btje:
Ow come on and go cry at home. When hardcore has a stable version i bet he will share. What would you like to do with buggy code?
[Galaxy S I9000 Android Development] SamHaLeKe:
kerel, I'm sure HC will release it when his new kernel is released first.
[Galaxy S I9000 Android Development] rschenck:
I agree completely.

This kind of fineshmecking and focus on the letter rather than the spirit of GPL encourages all kinds of backstabbing and whining between devs and their supporters here.

Rather than allowing open source to foster cooperation such thinking just makes it all a junior high school pissing match.

We have already lost too many talented devs over this kind of behavior.....STOP IT.

and yes, I know....you are just trying to enforce a rule, the rationalization of every small minded bureaucrat....but it is a rule that XDA itself explains is an unenforceable suggestion. Grow up.
[Galaxy S I9000 Android Development] renaud:
Unfortunately it's not true. hardcore doesn't always release source in time.

As soon as there is a release it is mandatory to release the sources. What hardcore does right now is illegal. You cannot release a binary without sources for the linux kernel.

He saw my posts, choose to ignore them instead of releasing. Don't tell me it's hard to release, all you need is to make a tar of your source, so it takes less than 10m, there is no excuse.
[Galaxy S I9000 Android Development] renaud:
He released a kernel, releasing source is not an option.
[Galaxy S I9000 Android Development] .Slane.:
It's first TEST kernel version with first release 2 days ago, we always had sources for nearly all versions for Froyo Kernel. Have you ever ask for Samsung the release of pre-JPM kernel sources ? Let have a stable release of K15A and Hardcore will as usual make available the patch against Samsung release. Indeed githut is a more convenient way to expose source, but nothing in GPL make it mandatory.

I hope having nearly the same logo than OpenBSD for your kernel doesn't mean that you like Theo de Raadt and his "Copyright fundamentalism".
[Galaxy S I9000 Android Development] renaud:
Obviously, yes, that's not an option, if it's that buggy, he must not release it. If you think it's too buggy, just don't release and you must not release source. If he judged this stable enough to release, source _must_ be released.

Let's do a comparison. If samsung releases many roms, but never releases any source claiming it's too buggy, would you allow them not to release? no.. So why would it be different for hardcore?

GPL is GPL, if you don't like it, don't use it. I release most of my code using BSD licenses, but I still comply with GPL when there is a need.
[Galaxy S I9000 Android Development] andip71:
Come on. Relax and have a beer... or five.

GPL... yes. But lets keep realistic now. As soon as it is stable you will get the sources.

Until then... what about improving your fugu kernel instead?

Cheers

Andi
[Galaxy S I9000 Android Development] renaud:
Leaks are illegal and not released by samsung, so they are not under any obligation to release source sinc they did not distribute it outside.

Theo de Raadt is difficult, but he helps opensource quite a bit, even if you don't understand it.
[Galaxy S I9000 Android Development] renaud:
Thanks for the suggestion of improving my kernel, I will.

Being stable or not doesn't mean you are not forces to give out source. Especially as hardcore probably use some of my code.
[Galaxy S I9000 Android Development] rschenck:
Maybe he can't until he gets Hardcore's sources. That sort of cooperation when done openly is part of the reason for open source. Add that possibility to the fact people seem to be having a lot of trouble with fugu over in the ROM Kitchen thread, and another possible reason for his urgency presents itself.
[Galaxy S I9000 Android Development] KennyLegend:
I agree.

Sent from another GALAXY
[Galaxy S I9000 Android Development] :
Is it too much asked to have the GPL discussion in a separate thread or via personal messages. This tends to go on for pages and pages and clutters the thread of the actualy subject.
