But those benchmarks dosent really prove that oc does not make your phone faster...the games are better with oc on my grand imo:p
[Galaxy Grand Duos i9082 Android Development] naufalhadyan:
Well then maybe you will do just fine with version 0.9. ;)

I personally get around 3-4 reboots a day with OC to 1797 MHz on version 0.9 (SmartassV2, SIO). Too little performance gain for the added instability... It's better to have more frequency steps between the regular frequencies rather than adding more OC frequencies IMO...
[Galaxy Grand Duos i9082 Android Development] k2wl:
I will add more frequency steps with oc in next version. But be care full what you choose. ..

thanks for testing out. I didn't know my kernel can achieve that much:laugh:

you are right. I am gonna add more small frequency steps with more oc in next version with more performance tweaks.

Can anyone test. How much free ram there? Is it more than before?
[Galaxy Grand Duos i9082 Android Development] naufalhadyan:
Amazing scores :silly: I don't really trust benchmarks to measure real performance but that's a pretty tweaked phone you got there. :D

Free RAM is the same as before when using version 0.9 and 1.0. There's probably a little difference but even if any, I can't notice it. RAM usage on idle is consistently around 300-350 MB (with CM11 it can go as low as 270MB). Do you ask this because of the kernel samepage merging? It doesn't make much difference...

if yes, then there is more to this problem.

PM me logcat. i will look into it.
[Galaxy Grand Duos i9082 Android Development] CoolDevelopment:
No,it has something to do with changes I made to my kernel. I was thinking it could have something to do with memset pacth for linaro, but the problem is probably zRam, which is not enabled in your kernel.
[Galaxy Grand Duos i9082 Android Development] k2wl:
i think its color banding issue definately.

because in old days, and still i am a proud owner of LG optimus p500-one phone:good:, when we are trying to fix ICS for or phone, this kind of pictures were common, it is called as colorbanding.

is it that.?

[Galaxy Grand Duos i9082 Android Development] naufalhadyan:
Does OTG even work on Grand?
[Galaxy Grand Duos i9082 Android Development] jayc137:
The S2plus (which has the same board aka capri) has OTG working.Not much research has been done about the OTG issue on grand.Some say the hardware doesn't support it.
[Galaxy Grand Duos i9082 Android Development] k2wl:
I think mainly our framework doesnt support it.

its in kernel already.

now its in rom part, which has to notify it.
[Galaxy Grand Duos i9082 Android Development] jayc137:
So you mean to say the hardware doesn't support it ?
[Galaxy Grand Duos i9082 Android Development] k2wl:
Nope i mean , our software doesnt support it yet...
[Galaxy Grand Duos i9082 Android Development] tekkenl0rd13:
As far as I know, OTG is hardware related and it has extra pins for the data.

And if it can be enabled through the I rom(software) i think [MENTION=3117667]pawitp[/MENTION] can and will be enabled it for a long time.
[Galaxy Grand Duos i9082 Android Development] k2wl:
Have you seen our kernel source ? our baffin board file, clearly mentions OTG capabilities. So i dont think samsung devs are fools who kept code for OTG in kernel.

even our device kernel config had enabled OTG.....
[Galaxy Grand Duos i9082 Android Development] jayc137:
So what should be the problem acc. to you ?
[Galaxy Grand Duos i9082 Android Development] k2wl:

I do not get much time to stay on a custom kernel as I am always flashing a new version of RR every few hours. Testing stuff. But whenever I do stay on a build for some time, I flash your kernel.

[Galaxy Grand Duos i9082 Android Development] iceyhotguy:
k2wl, first and foremost, thank you for the frequent updates with the ever-improving kernel.

A couple of things,

- I tried modifying several features of VM and systcl but they don't seem to be writeable while using evolution kernel (checked with both v1.2 and v1.3) while they are easily modified using stock CM11 based kernels. For example, values like writeback_centisec, dirty ratios are not writable while overcommit_ratio and vfs_cache_pressure are easily modified in evolution.

- In recent versions you mentioned you have self optimized the KSM feature, and in the apps it says Ultra KSM detected. I trust your judgement on the values implemented but I can't seem to able to access the values used through apps. I've been reading about kernels so I'm curious what values/settings are best suited.

- Lastly, no offence, but the OP says

While I get xenon92 might have suggested it to you personally and this is your way of thanking him, but there should be credits to h0rn3t as well, the developer of the Performance Control app - http://xdaforums.com/showthread.php?t=2444376

Gonna try the v1.4 now, thank you :good:
[Galaxy Grand Duos i9082 Android Development] naufalhadyan:
Not a problem dude, none of us here speak english as our first language (except maybe Darian71) so even the worst grammar from Google Translate is acceptable, as long as it being understandable. ;)

Gonna download and test version 1.4 now~
[Galaxy Grand Duos i9082 Android Development] k2wl:
values like writeback_centisec, dirty ratios are hard coded. thats why.

i will revert the changes if you guys want it back.

i will update the post. for h0rn3t.

thanks for pointing out.

Evolution kernel 1.5v have bluetooth issues if flashed on the latest Ressurection Remix 02142014 build.
[Galaxy Grand Duos i9082 Android Development] iceyhotguy:
1. You are quoting me instead of the developer :p

2. While posting problems faced, please describe the problem occurring as best you can in detail and always get a logcat so the developer can address the issue properly and quickly.

3. I'm flashing RR now to confirm, will report back.

How to take and report a logcat:

All you have to do,

1. Get an app like Catlog - https://play.google.com/store/apps/details?id=com.nolanlawson.logcat

2. Run it, grant root permission, it'll start reading logs immediately

3. Press option and select Record

4. Re-create the problem

5. Go to notifications, and press the Catlog icon to stop recording and save the Catlog to a file

6. Upload the text file here for the dev

Hi [MENTION=943196]k2wl[/MENTION] using the kernel for 2 days now I have some observation if u allow:what:

And i dont think it requires logcat. Just for info,

First is battery is more discharging than the previous build and unknowingly battery is going down. I used map for 1 30 hours continously my battery came down from 70% to 14%.

Second is i tried using different performance meter's but the performance was not that in previous build { i tested personally, may differ user to user)

Third is charging time has increased compare to previous build.

For time being I have reverted to 1.4 build which i think is stable :D
