Hi! be sure the honor is shared.
Thanks for your answer,
I see you not only speak Korean and English languages with ease but also I2C at least
Yes the absence of any sign of documentation about mDNIe forced to use the reverse-engineering approach ^^ as I had no experience in Kernel development a few months ago it was a lot of trial and error.
Now Samsung have given a little details in their new source code release about mDNIe controls, which is definitely a move in the right direction.
I'll try to get the doc for this chip.
I agree the first Voodoo sound implementation was crude, that's why I never activated and rewrote it from scratch for the release.
You're a much more experienced kernel and embedded developer than me!
Come on, don't be so shy, I'm just a rookie compared to you
See ya!
I saw voodoo home page few month ago.
At that time, I did'n t know who are you. (I just know your name gitweb a month ago)
Now, you are famous in korea. many people are waiting voodoo kernel.
but, most people don't know about voodoo kernel.
(as I know, korea voodoo kernel is stock kernel, but, initramfs is from voodoo)
Frankly speaking, It is not true that I saw your code carefully. (maybe 1-2 hour)
but, I feel you make a ceaseless effort.
Although, I didn't use your code. This is from your inspiration and motivation.
If I didn't see voodoo home page. I may could not think this application.
so, A half of this application is yours
I don't have plan to improve the functionality. If application is complicated, It needs more maintainance and bug fixing effort. (It is beyond my hobby)
This application does not work, when kernel version is changing.
At that time, I should recompile the module. so, I want to keep simplicity.
Detailed technical note and register that I used is already in my homepage.

It's 6.AM In korea. I'm so sleepy. I am anxious tomorow.
p.s)
I am poor at english. It is nearly translation. (^^)

성의는 고맙지만 한국분들은 여기에 안 오셨으면 합니다. 여기는 외국사람들을 위하여 만든 공간입니다. (그래서, 한국분 한테는 안알렸습니다.)
또, 지나친 관심이 좀 부담스럽네요.
dowkim10 Korean are welcome on XDA i think, as everybody on the planet!
but yeah it works better in English
but yeah it works better in English
Thanks for the app.
Just a tiny issue on the saving of the Sound Profile.
When u save the current settings over and over again to the SAME profile name, the app does not override the profile but created a NEW profile with the same name.
For example:-
1. Save Current Settings to profile --> STANDARD
2. Save Current Settings to profile --> STANDARD (note - same name as #1)
3. Load Profile, u see 2 STANDARD profile name.
Hope this can be fixed.
But all in all, it works fine!

Thank you for your information.
I already know this things When I add profile feature(save,load,delete)
But, you can delete first STANDARD by delete button easily.

This application is made for enhancing or changing some feature for galaxy S
Requirement
1. machine
galaxy S (all variant)
2. version
Froyo (kernel 2.6.32.9)
3. rooted phone*
(*After checking "use with unrooted" option, you can remove rooting)
Feature
1. IO scheduler change
It can change CFQ(default) to deadline for some block device.
This change affect response time of disk IO.
(If you are using the application which handle many small files. You can feel better responsive reaction)
2. LCD color adjustment
(Test version)
This can be helpful to adjust so blue or yellow LCD.
3. Sound (3D, Hardware Equalizer)
It affect all system sound. so, If you change some parameter, all system sound(music, movie, radio..) will be affected.
How to test.
When you are hearing the music, As soon as changing the parameter, you hear different sound.
4. Memory Manager
Because It is controlled by kernel and android framework, It is more powerfull and efficient then memory killer.
for more info visit this link (thank to androcheck)

5. Over Clock (1.2Ghz)
OC feature is harmful to your phone. so, I put some restriction for preventing abuse.
(OC kernel user do not use this feature. I didn't consider OC kernel. and, I don't know about OC kernel)
6. Firmware(kernel) writing
you can write kernel(zImage) directly. and. can enter into recovery,download mode via this app.
7. use this app with unrooted
(Fort this. you must check "use with unrooted" option. before unrooting)
8. Bad block check (for ext filesystem)
If There are bad blocks on your ext filesystem. You can experience lag,abnormal app exit,slowness
9. key(Button) remaping Feature added
Volume Up,down key can be remapped to other key. (This is tested on M110S)
10. Touch gesture
It can map total 6 key button with Touch gesture.
11. Orientation Fix (especially Landscape mode)
It is helpful to view Landscape lying
How to download
search with this keyword on the market (galaxy tuner or d.w.kim)
Technical note
* LCD color and Sound function is accessing chipset resister directly.
* because, I don't have mDnie(LCD), wm8994(Sound) datasheet. I could not implement many feature.
* all system changing is volatile. so, If you reboot your phone. all system state is identical to original state
* OC function in this app change governor(performance, conservative..) policy. so, consider changing governor policy from like set cpu app
* running without rooting is a little tweak. It still require root privilege.
* more detail technical note

Hi Jopps
I can share you my settings in vm manager, they are not fully optimized but much much better then the stock settings here on all areas on the phone(cpu, memory, io score, 2d and 3d quadrant score).
I am running stock 2.2.1 image and the latest firmwares from Samsung and Voodo kernel
VM settings:
SWP:100(old value) new value(67)
VCP:122(old value) new value(128)
DEC:14(old value) new value(15) going under 13 slows down the phone a lot and going higher then 15 slows down the overall performance on the phone a lot + it uses more battery then. So a value between 13 and 15 is fine here
DWC:10(old value) new value(18) more description text on this and the other values are coming
DRA:5(old value) new value(100) setting this to 100 tels the phone to put larger dirty page values in system memory, something that makes the phone a lot snappier and the performance and battery is also positively affected
DBR:6(old value) new value(14) not sure how to describe what this is, but to low value here drops the performance down drastically and to high also does that + to high uses a lot more battery. I think that 14 is a good combination of performance vs battery usage (this value and some of the others can be changed if i find better values in the future).
Application cache settings:
FA:10MB
VA:15MB
SS:25MB
HA:40MB
CP:50MB
EA:70MB
With these settings my phone is very responsive and stable and are using little battery
But which settings that are best varies from phone to phone and the applications environment after all!
But give these settings a try and see if you are happy with them :-D
Updated 05.04.11 with better values for better performance and batter saving.2Hi dowkim10, this is interesting work.
I thought a lot about how to design the Voodoo sound driver and the consequences of the design chosen.
I took a different approach than yours: coding also a new driver, not as an independent .ko but using hooks in the actual source of the sound drivers to stay portable.
I believe a few limitations of the design you use are :
- It will be hard to add improvement like the microphone input auto-gain I prepare for the next version.
- Same thing for the FM radio bass solution
- Next to impossible for the upcoming audio jitter issue resolution
- Pretty hard and encumbered for adjusting other various input/ouptut gains/levels here and there
As kernel modules, like the scolor.ko and ssound.ko have a lot of power, in theory everything is possible but Galaxy S devices have so much different versions that implementing a module overriding some functions from the actual driver without breaking anything on a device or another will probably lead to very dirty code and headaches to maintain.
I thought of implementing everything using the wm8994_write dynamic register rewrite technique described here, also by inserting .ko modules like you do.
But here is what's in Voodoo sound source code:
https://github.com/project-voodoo/l...-voodoo/Kernel/sound/soc/codecs/wm8994.c#L215
https://github.com/project-voodoo/l.../Kernel/sound/soc/codecs/wm8994_voodoo.c#L270
By sniffing sequences of register address / value pairs, you should be able to recognize some patterns and add custom changes into it to extend your implementation.
But again, quite a dirty design
Good think of course it's the awesomeness of not requiring a custom kernel.
Of course my approach requires to publish every single piece of Kernel work as GPL and convince a lot of kernel developer to apply these patches, including eventually Samsung and Google.
But it's how I like it
As you distribute and insmod .ko modules, you're not forced to release source for them, but I advocate for Open Source.
Also, you will find a lot more code and ideas you will be able to re-use in the next Voodoo sound versions, about how to handle the parametric EQ and avoid saturation, and a lot of things like that.
Again, GPL will be a lot preferable.
bug report: mDNIe settings you use are lost after running Video player, Camera application (every app sending new mDNIe settings affecting the color response)

Hi,
I just wanted to share my VM settings.
I am using this settings and it is really working very well and snappy, they are almost 100%perfect tuned now;-)
Have fine tuned these over almost 3 weeks have tested all values from lowest to highest values!
VM file cache setting:
*SWP=32(Chose a low value her to use the system memory instead of file buffer from internal file system for applications, that is minimum 10X slower) But you must have enough free ram to get it working good.
This setting makes the phone respond a lot more better!
Don't chose something under 25 because that will have the opposite effect, etc no free ram at all and the phone gets slower and lags a lot.
*VCP=63(It is for cleaning up unused application cache a value about 60 is best here) Have tested it up in about 115 a value like this cleans to much of the cache so it must load for exempel all the content in android market every time and makes the phone slower but frees up resources.
Setting this value to low will make your phone slow and laggy!
*DEC=16(Don't know exactly what this is for but think that it has something to do with the cleaning of unused file buffers on reading sequences)
This one works fine booth with low and high values, but you will get much more stable and faster reading time when you keep it one place between 15 and 20 With this value i get minimum 8mbs on SD card read speed test and maximum so much as 11mbs.
*DWC=19(Don't know exactly what this is for but think that it has something to do with the cleaning of unused file buffers on writing sequences)
This one too works fine booth with low and high values, but you will get much more stable and faster writing time when you keep it one place between 15 and 20 here to With this value i get minimum 5mbs on SD card writing speed test and maximum 9mbs.
*DRA=32(This ratio value tels the system to keep larger file cache in system memory if a higher value) This value makes the phone booth read and write much more stable and speedy, and makes the phone snappier if tuned right!
A value between 30 and 35 is best here, you wont win any speed on setting this higher even if you set it to max value.
The only thing the will happen then is slow down on the read and write speed and hangups when writing and reading things.
*DBR=34(This ratio tels the system to clean up large dirty pages i think)
This value also has something with the stability of the phone when writing and reading files, like the value above.
Keep this to in the range of 30 to 35.
But it works best on 34 have i figured out
Setting all of the above settings as i have described here has almost tripled the speed on my phone in some situations, and has also made the phone boot up ready in 50%less time. So it uses 30secounds less time before it is ready when cold rebooting it.
And the gaming performance is incredible also the performance in bigger programs
And for those that also wants my low application memory settings here they are:
FA=10MB
VA=15MB
SS=25MB
HA=45MB
CP=50MB
EA=70MB
These memory settings are final and optimal for my phone
Also setting these values makes your phone faster and more responsive then before.
I am using a custom kernel Voodo lag fix newest version so i have 40mb more ram then normal on this phone, so if you are not running this kernel you may have to lower these settings a little bit to keep the phone smooth and stable.
My phone is very responsive and stable with these memory settings
Hope my values helps someone with choosing right values and explains some what they are for.
I will keep updating this post if i find out that some of the values isn't perfect tuned, i can say that the last two values(DRA and DBR) are optimized completely to the limit.
And all the other values aren't far away from that to
And BTW don't be afraid to ask me if you have questions to any of the above
