need some info

so if we uv after installing this kernel do we have to uv all frequencies or just the top most one, moreover i can only set the lower most voltage in pimp but how do i check the range to make sure i am within 100 mv difference .. thnx
[G Tablet Android Development] tiger4j:
boltgd, I believe the settings listed in the 2nd post show the Max voltages. I'm guessing 1200 would be stock at 1.5 as the vertical table shows settings at 1300. So Max voltage (with 100 ov) are 1300, 1200, 1100, etc. I think that is correct.

Also, you should be able to set each frequency with its own UV.

I dont use SetCpu with this kernel. Download cpu master from the market and change the scaling governor to powersave. Then open PimpMyCpu back up and see if that works.
[G Tablet Android Development] ls430cw:
Just posted a 4638 on smart bench. Fastest I have pulled yet. Thanks for the great work!
[G Tablet Android Development] clemsyn:
I got second at 5700 ;) on antutu
[G Tablet Android Development] gkitab:
My market went to **** after flashing pershoots 1400. I fixed permissions and have done market fixes. So figured flashing clemsyns would give me more and fix market issue. Always looking to get most out of my electronics, so I would like to figure this out with clemsyns. Read about pimp my gtab and don't see what I'm missing. Why do I need another program to get it working if its made for pimp my. Do I have to do these extras or did I screw things up. Why did my market go to ****. Thanks for your help I appreciate it. Hope we can figure this out, thanks again for your help.
[G Tablet Android Development] TMYINC:
Im not sure why your market went to ****. Have you tried clearing your market data? Pimpmygtab is for setting voltages, cpu master allows you you to overclock and set a scaling govervor. Pimpmycpu wont work without a governor set. Im sure if you are running CM 7 you could set the governor under CM settings and not have to download cpu master. This kernel isnt compatible with setcpu so thats why it will not work. Hope this helps some. Good luck to ya.

strange.... I got 4900 on Antutu compare higher score using non-oc gpu

do I need to do anything for getting higher score?
[G Tablet Android Development] deltchon:
I am not seeing any improvements with the new kernel with gpu oc. Have it running at 1.5 ghz. It looks like the gpu is still running at stock for some reason. Does it need anything special?
[G Tablet Android Development] clemsyn:
Use smartbench and check your gaming index. You will notifpsyour gaming index go up with this kernel. Not sure why some benchmark don't go up, could be we are hitting their Max fps?
[G Tablet Android Development] dony71:
I go back and forth comparing performance between clemsynfroyo1.5pimpver2.zip and 1.5ver11gpuavpsystemocfroyo.zip

Testing with antutu, smartbench, quadrant .... all test shows pimpver2 has higher overall score

Game index in smartbench shows similar number

IO performance in antutu and quadrant which supposed to be higher when system bus oc appears not to be the case,

pimpver2 still shows higher number.

I'm confused now. Am I missing something?
[G Tablet Android Development] TMYINC:
Haven't had much time to try this out yet but I'm sure it will be awesome as usual. Thanks for all your hard work!
[G Tablet Android Development] Fredplex:
Clemsyn,

on that note, are you still working with a borrowed Gtab ?

What is your motivation to continue building these kernels for gtab when you don't own one? I (...and I'm sure the whole gtab community) am extremely grateful for your efforts and results.... I for one want to see you continue this and if it means throwing a few extra bucks into a pool to get you a GTAB helps that along I'll be the 1st one there...

...anyhow, I don't expect a response just was curious to know what keeps you building for gtab?

Thanks, FredT
[G Tablet Android Development] WattoDaToydarian:
I installed 1 .5ver11GPUavpsystemOCGingeer.zip on my gtab running VEGAN Ginger and my WiFi said error and wouldn't start, had to go back to Clemsyn1.5GingerMed.zip.

Also, when I checked the speed it was set to 1000000 as the max with 1500000 as the limit when before it was 1500000 as both.
[G Tablet Android Development] phdeez:
Maybe someone else can chime in (Short of converting to ext3, are there any other options? Is ext3 even an option for the internal memory?) ? I understand clemsyn (along with all devs) are busy... So I appreciate any feedback.
[G Tablet Android Development] SoNic67:
Internal SD memory probably needs to stay like it is.

Unless the bootloader knows about the NTFS, there is no way to load the kernel (where the NTFS support resides).
[G Tablet Android Development] Mrhorology:
Any reason why I keep getting "Service call failed" in quad?? Smartbench works now, but quad doesn't work.
[G Tablet Android Development] clemsyn:
Yup, still working on the borrowed Gtab :) I used to own one but then I had screen issue with the first one and I replaced it, then had the some issues with the second one. I guess I just had a bad batch coz this Gtab has been working great so far. Anyways, I really would like to see the most on what this Gtab can do. I will be returning this in a day or two so I would like to release my Final version before then.
[G Tablet Android Development] clemsyn:
Make sure you clear the data of PimpMyCPU and restart after installing version3. Or you can uninstall PimpmyCPU and then reinstall.
[G Tablet Android Development] phdeez:
Thanks for the response... but I'm actually talking about the 13GB partition (mmcblk3p1) that is created after installing CWM & partitioning to 2048MB, so the "rest" of the internal memory is set to /sdcard (~13GB?). Take a look at my pastie.org link for the entire output... but here's a snippet:

# df -h
Filesystem Size Used Available Use% Mounted on
...
/dev/block/mmcblk3p2 1.8G 76.9M 1.6G 4% /data
/dev/block/mmcblk3p1 13.1G 67.7M 13.0G 1% /mnt/sdcard

# mount
...
/dev/block/mmcblk3p2 on /data type ext3 (rw,nosuid,nodev,relatime,errors=continue,data=writeback)
/dev/block/mmcblk3p1 on /mnt/sdcard type ntfs ([b]rw[/b],relatime,uid=0,gid=0,umask=00,nls=iso8859-1,errors=continue,mft_zone_multiplier=1)
#

Since ext3 is recognized upon boot and supports >4GB, I think I have to format the /mmcblk3p1 as ext3 (like mmcblk3p2 which is /data). But, I was hoping for a direction on using ntfs for ease of use.

My gTab boots and operates fine, just "right now" I can't use /sdcard (which is 13GB of the internal memory) even though mount shows the partition as RW, not RO.
[G Tablet Android Development] gkitab:
Thanks very much for explaination. Ive cleared cache and davlik cache. Yes cleared market data and force stop, then clear Google services framework and force stopped, Rebooted, still fC on market. Is there a way to obtain an apk for CPU master, or Is it a paid app, while I figure out wtf my market is doing. Thanks for the guidance.
[G Tablet Android Development] TMYINC:
You can get CPU master free off the market. There is a paid version but the free one does what you need. For the market issues. have you tried running fix permissions in rom manager or in clockworkmod recovery?

Edit: Just realized you can't download from the market, so unable to get cpu master lol. Sorry, Im half asleep. Let me see what I can find for ya.

Edit #2: Check your inbox. I sent you a PM.
[G Tablet Android Development] gkitab:
I've tried yesterday to fix permissions with Rom manager, jrummys root tools that I use on my Droid x, and also jrummys Droid oc app that I use on my x has fix perms to. Tryed all that again today also.

I'm gonna try via market on browser.

Thanks.
[G Tablet Android Development] clemsyn:
Market issue is related to the build.prop. I think google guys did something. There is a fix to edit the build.prop somewhere. I have incorporated the fix in my next combo and it's working. Will release the combo tomorrow.
[G Tablet Android Development] TMYINC:
Check your PM's first. ;)
[G Tablet Android Development] TMYINC:
Sweet! Sounds good man, and thank you. I dont know much about that kind of stuff but I was thinking about looking at the fingerprint ID or whatever. Not sure if that has anything to do with it or not. Just making stuff up as I go lol. Excited for your next release!
[G Tablet Android Development] gkitab:
Thanks to both you guys. I think I should be on my way tomorrow when I tinker. Not Donna get into now. Gotta go get some zzzzzzzzz.

I assume u are using avpsystem of kernel

can u compare with pimpver2 kernel?

my comparison shows pimpver2 has higher score

this does not make sense cause avpsystem kernel has gpu and system bus oc
[G Tablet Android Development] SoNic67:
Yes, I am using the avpsystem kernel. And yes, the video is not faster in this benckmark. I didn not install the pimpver2 yet, I have obtained with the pearshoot kernel at 1.4GHz:

AnTutu score: 4651. CPU Integer 1555, CPU Float 1482, 2D graphics 211, 3D graphics 200.

Now, I cannot be 100% sure that that bench uses the HW acceleration in Tegra2...
[G Tablet Android Development] onesikpuppy:
Ok, can't figure out what I'm doing wrong. I'm running Vegan-tab ginger with the ginger kernel from the OP but when I try to run Pimp my CPU I get "Error, sorry you are probably using an unsupported kernel..."

Download CPU master from the market and set governor to powersave. Its a free app.
[G Tablet Android Development] sonkey:
Hello All

I was wondering, I upgraded to the newest Kernel.

What settings should I use for the lowest voltage for each selectable frequency in pimp my Gtab?

I was able to use the ultra low voltage kernel from before.

Any advice?

Also what is the difference in using powersave or performance settings for the govenor in Pimp my Gtab

Thanks, Rob
[G Tablet Android Development] clemsyn:
If UV worked well for you then the ranges for UV was 700mv - 1175mv.
[G Tablet Android Development] kodakeos:
so many versions!!! Aaaghh!!

What do i need to use Pimpmytab with this Kernel for gingerbread with the newest kernel?

pimpmytab.apk and avpocginger.zip?
[G Tablet Android Development] clemsyn:
Yes, make sure you install the kernel first and then PImpmyGtab.
[G Tablet Android Development] Blades:
This GPU oc bumped my graphics benchmarks @1.0ghz above #s I was getting at 1.7ghz with no changes made to avp/vde/system or gpu. It does work. Now, the next thing to tackle is getting the external memory controller, memory controller, and finally the memory itself to 800,400,400 respectively.

That should put some pep in the gtab step.

Oh and antutu bench for me was top 10. WOOT! I want gtab to be #1. Muhahahaha
[G Tablet Android Development] clemsyn:
Thanks to you re: GPU OC'd..anyways, just let you know. I think rouguecat54 got the top score since I shared to him our sacred 1.7 ghz kernel :)
[G Tablet Android Development] TMYINC:
Hey I want that sacred kernel! lol
[G Tablet Android Development] 1loudsvt:
yeah i want that sacred kernel as well or directions on how to do it myself lol
[G Tablet Android Development] clemsyn:
Voltage limits and steppings on my 1.7 is way above nvidia's so I dare not release it. I'm testing it on this Gtab that I also don't own (with approval from owner) and to be honest, its working great (with a little mod). If you really want to risk it, then PM me your email and I'll send it your way.
[G Tablet Android Development] Fredplex:
So what do you think you'll land on as your final release wrt freq? seem to recall that you got it pretty stable and not too hot at 1.6 ?

(ignoring froyo / GB difference) you have have 2 streams of your OC'd kernel. One with CPU OC'd to 1.5 and the ability to dynamically tweak voltage (via pimpmyCPU) and a 2nd with all of the 1st PLUS OC'd sys bus and GPU - does this about cover things?

If so I am wondering which direction you are leaning towards? keeping both or getting the 2nd stable enough and sticking with that....

for general activities I have not seen much of a difference with the AVP/GPU OC'd kernel but for gaming with accelerated drivers at play this edition of the kernel I'm sure has a clearly seen benefit. (although I believe I read a comment from Blade saying he achieved some max with the AVP/GPU OC'd kernel.

Thanks... FredT
[G Tablet Android Development] Blades:
Well system bus may be important in getting memory freqs to Tegra 2 250 3D level.

I use 300mhz avp/vde. I want to try to get everything up to t25/ap25 spec. That means 400mhz ddr, 400mhz gpu. Already at 450mhz gpu, but it didn't seem to make any difference versus 425mhz. In fact, something could be limiting the gpu clock as we have no way of checking if its reaching its max-clock other than consistently higher gpu performance. But everything lines up on the code side of things.

But yeah, there's no reason why we can't run these at Tegra 250 3D specs, its the same thing.

http://en.m.wikipedia.org/wiki/Nvidia_Tegra

That reminds me, I forgot to check the disassembly pics and see whats what with our RAM. Perhaps we need more voltage

Clemsyn Is Doing an Awesome Job

Just wanted to post here since I finally can, check out this post called Dirty :D

http://xdaforums.com/showthread.php?p=13356276#post13356276

Yes, clemsyn sent me his kernel, and I have the honor of being able to show how good it is. Check out this site:

http://www.antutu.com/software.php

His kernel has allowed the G-Tab to break the 6000 mark on this benchmark.

My highest Quadrant score has been 2741 to date.

In Smart Bench, I posted a 4189 for productivity

and a 3502 for Games.

This is an awesome kernel!!!!

Due to PM requests...I will go ahead and release the 1.6 ghz and 1.7 ghz kernel on this post for froyo and gingerbread. Pls be advised that I do not recommend such voltages (but has been working great for this Gtab at 1.7). Also, I have rolled back the wifi drivers.
[G Tablet Android Development] SoNic67:
Can they have the voltage cotrolled with Pimpy?
[G Tablet Android Development] clemsyn:
yes it will, please use it to try to undervolt as much as possible with stabilitily in mind ;)

Im missing something... I flashed 1.7 and cleared dalvic and cache. I can't set the voltage higher than 1.4 and I don't see that init.d file to edit. Running cm7 (and before you say it, I asked and Clemsyn said it would work even though its not froyo). Ideas?
[G Tablet Android Development] austontatious:
Figured it out. Setcpu doesnt seem to support the frequencies. CPU master fixed it. I flashed back to 1.5 to have wifi back but didn't notice any stability issues at 1.7

[G Tablet Android Development] nitefallz:
Going to try 1.6. 1.7 freezes on me sometimes at full voltage.
[G Tablet Android Development] clemsyn:
If you installed pimpmygtab before, make sure you uninstall it before installing the new kernel, then reinstall pimpmygtab. Then open it and tweak accordingly, then make sure you save the tweaked voltages to profile and save it to boot at the current profile.
[G Tablet Android Development] nitefallz:
Did this a few times, didn't seem to like 1.7 at all. 1.6 seems to be running good.
[G Tablet Android Development] SoNic67:
This happend to me too. It won't be stable with 1.7GHz, but works at undervoltage at 1.5 and regular voltage at 1.6... For now I settled at 1.5 (for battey life).
[G Tablet Android Development] clemsyn:
1.5 ghz is definitely the max speed that I noted at Nvidia kernel stuff so most device should be able to support a max of 1.5ghz at 1250mv for tegra. 1.6 - 1.7 is not within the speed so I really consider these the overclock speeds.
[G Tablet Android Development] SoNic67:
Yes. I got it running at 1.5GHz with 1175mV - I think is awesome.
[G Tablet Android Development] roberto188:
Unstable

As others have posted, at 1.6 and 1.7 ghz my tab froze several times. 1.5ghz is rock solid though.
[G Tablet Android Development] racketier:
Anyone have any suggestions as to the best way to lower voltages using Pimpmycpu and then test for stability?

Here's what I'm currently trying:

1. Pick a frequency to test. I usually start at the highest (1.5ghz for me)

2. Use SetCPU to make the Max and Min frequencies the same (1.5ghz in this example)

3. Stress test using SetCPU or PimpMyCpu for a few minutes

4. Lower voltage by one increment

5. Stress test again

5. Repeat steps 4 and 5 until having a lockup or issue, then returning to the last known stable voltage

6. Start over at step 1, picking a lower frequency

If anyone has any suggestions to speed up this process, or to ensure stability besides just using the stress tests I'm all ears.
[G Tablet Android Development] Blades:
Discovered a few new tweaks and such..

Thats 4562.. btw.. anyone know of a decent screen shot app?

Also got an average of 5200-5225 for productivity score on smartbench.. games score is at 2500+.. running VegaNB5.11 (Android 2.2).. For some reason the gb roms are scoring pretty damn high (~2800) - i think thats mostly because they run the benchmark in an itsy bitsy window. heh.

also discovered something.. slightly or possibly alarming.. I use a simple script to change my frequency limits when needed.. takes 2 arguments.. displays values before and after changes.. so it was 1400mhz max,216mhz min..

did this while i was logged into my tablet via ssh term.. I pressed enter and began to rotate the device shortly after (to generate some sort of CPU load). below is the command and resulting output

/sys/devices/system/cpu/cpu0/cpufreq/ # cat cpuinfo_cur_freq && sleep 1 && cat cpuinfo_cur_freq && sleep 1 && cat cpuinfo_cur_freq && sleep 1 && cat cpuinfo_cur_freq && sleep 1 &

nice huh? Is it reliable? eh.... maybe.. I should probably do that again but also check the status of cpu1.. (cat ../../cpu1/online).. just did.. it stayed offline the whole time.. made it go online (echo 1 > ../../cpu1/online).. same thing.. violating the scaling_max_freq whenever it pleases..

now I'm not using this kernel exactly.. its my own.. and I initially had the OC stuff from pershoots kernel and then began modifying to my crazy goals (like OCing the GPU and the video decoder engine - vde). So this could be my doing..

But, if anyone is wondering.. feel free to check the cpuinfo_cur_freq under moderate load with scaling_max_freq set less than cpuinfo_max_freq..

Dual Cores

Does this kernal utilize both cores? When I use cpu master it says 0 next to cores.
[G Tablet Android Development] nitefallz:
I don't see anyplace that says "Cores" but under cpu info it says cpu 0, some info, a blank line, then cpu 1 I think

Ethernet Support

Please excuse me if this is a dumb question.

I am trying to get the Ethernet connection on my G Tablet dock to work but I'm not sure if the support comes from the Kernel or the ROM.

I have tried some changes recommended in a post to add some settings for the eth0 device without any luck.

Any ideas?

Thanks.
[G Tablet Android Development] Blades:
Type dmesg | grep -i SMSC

Point of that is to check the kernel log for any mention of the USB Ethernet driver smsc95xx.

[G Tablet Android Development] Blades:
Ok that means the kernel has support, so its just a matter of following those instructions. If you have wifi off, certain apps will give you **** about no connection.. the browser says it cannot load the page because there's no internet connection... and then loads it.. only says that once.
[G Tablet Android Development] pgonza02:
Just tried it again and I think it connects OK but it does not get IP, etc.

Is there something like ipconfig to get an idea if it's getting an IP address on each interface?

Thanks.
[G Tablet Android Development] Blades:
Yes. ifconfig, but the version on VEGAn b511 is linked to 'toolbox', its ****. Replace it with a symlink to busybox ifconfig and you're good to go.

Script:

#!/system/xbin/busybox sh

busybox mount /dev/block/mtdblock3 /system/ -o remount

cd /system/bin

mv ifconfig ifconfig-old

ln -s /system/xbin/busybox ifconfig

The interface may be down, so upon docking... bring it up.

ifconfig eth0 up

Also- there's always your router's web interface (provided that its the dhcp server on your network).
