You and rusty, ha what a joke for me ;).

When I had written that I can be possible true with my 56 years and three heart attacks the last 16 month.

You can make good jokes but think about my heart CTXz ;).

Possible I can help too about kerneling.
[Galaxy Tab 4 Original Android Development] CTXz:
Wow... I feel sorry for you man...

I wish you the best for your health!
[Galaxy Tab 4 Original Android Development] mike2nl:
CTXz:

Thanks and no issue at all. In that moment I had seen things and I am thank full that I am still here to help and learn, so far possible ;). Nothing to feel sorry because I can make jokes too and i have fun. So let's go. Hey, Ho, let's go.....was that U2?
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Possibly

I found a file regarding the gpu , and it shows the freq steps and it is also identical to what's in clock pxa988.c. Maybe if I change that I will be able to successfully ad GPU oc!
[Galaxy Tab 4 Original Android Development] engine95:
Did you find it buried under /marvell/galcore/ something something?

That's where I've been trying things. But no luck yet.

Nice work! Keep pushing the limits! Antutu scores in 16000s
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Its getting better but I wonnt be completely happy till I see scores hitting 19000s or higher:D and to anyone curious bout GPU, me and [MENTION=1280108]engine95[/MENTION] are working on it hopefully we can figure it out here soon
[Galaxy Tab 4 Original Android Development] gammaxgoblin:
With all this positive momentum, maybe you can crack an aosp ROM too ;)
[Galaxy Tab 4 Original Android Development] gammaxgoblin:
Are you building off of the OD1 kernel?
[Galaxy Tab 4 Original Android Development] doctazz:
Great job! My games run faster now, even though this is only a slight bump from 1344. Hope you can OC the GPU effectively. That would really help some of the games I play run more smoothly, including Looney Tunes Dash. OCing the GPU would also help 2D video run better. Running this kernel on a recent Acheron ROM install. :)
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Gamma I actually need to do that lol and doctazz I'm glad to hear games are playing smoother, I'm trying to finagle with the GPU but man it is b**** its so hard to work with and It don't help when the GPU show a freq of 0. but me and engine95 are trying its only a matter of time before I/anyone will see significant changes and regarding the issue [MENTION=1280108]engine95[/MENTION] I went through es file explorer to see the GPU info and I don't know if it will help but its worth a try anyways both 3d and 2d max freq shows 416? Maybe instead of changing the gcshader and 3d alone we change all that uses that 416 freq and change that? I would try tonight but I got work in the morning.

[MENTION=6332061]beany23[/MENTION] I actually got 702 to boot up and show up. But it wiped out all the clocks. So I know I'm close. I'll just keep plugging along.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Was that from the files I was talking bout or how'd u do it?

And u say other clocks that won't show up? Sounds like all related to the CPU GPU and what not are in the same file that's y GPU now shows up but CPU doesnt? Try looking into clock.c. we need to see if the GPU runs either on the same rails as CPU or which PLL it is running off for e.g. its running on PLL1 like my max CPU rate it won't show cuz it on the same one so maybe changing it to like PLL2 or PLL3

---------- Post added at 03:49 PM ---------- Previous post was at 03:38 PM ----------

Also if we effectively oc GPU it also might oc the vpu as a side effect which hopefully will help with smoother cinematic scenes or videos in general
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Tomorrow

Tomorrow I'll post a new built min freq is 156 I have an issue with higher frequencies because they simply don't show up like the 156 and 208 steps do I'm trying for 104,208,312,416,520,624,728,832,936,1066,1170,1274,1376,and 1482. Give me a couple days max and I'll get it!
[Galaxy Tab 4 Original Android Development] The_Anomalist:

What was your original one?
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Its still a decent jump from original lol and can anyone point me in the direction for the sm t230nu kernel source? It would be nice to use my ir blaster
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Try vellamo for benchmark and tell me you scores its an app y'all prob heard of its pretty accurate compared to antutu
[Galaxy Tab 4 Original Android Development] engine95:
[MENTION=6332061]beany23[/MENTION] check this post and thread. I guess the one I found us the newest. I think it's the middle one of the 3.

[Galaxy Tab 4 Original Android Development] The_Anomalist:
Is that the kernel source? And plz do tell me how u did the 702 for gpu , I wanna see if it will shed light on y the CPU freq don't show anymore. It almost sounds like the changes needed are indeed in the same file
[Galaxy Tab 4 Original Android Development] engine95:
Yes.

Using those files I've told you about.

I got 416 and 702 to show in gpu. And it kills 156 and 312 GPU. But it also kills all CPU but 1066 and 1344.

The good news is, I was able to get logs and it all has to do with dvfs. What a pain in the @$$ that thing is!!

The bad news is, I need to start from scratch again because I've made so many changes that its just becoming a mess. And the changes I make, make no difference.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Ok dvfs u say, alright I guess part of the focus needs to be there since dvfs is changing stuff to were it totally knocks off all steps except 1066 and 1344. Also maybe checking out dvfs pxa1088.c starting at line 50 it shows max freq for gpu
[Galaxy Tab 4 Original Android Development] The_Anomalist:
[MENTION=1280108]engine95[/MENTION] ur right it does wipe clocks for CPU but what weird is now my GPU doesn't show at all and regarding CPU I got 1586 to show but 1378 728 832 520 416 don't show up but 104 208 312 624 1066 1482 and 1586 do. I want to add more but I can't figure out y they don't show up. They are all the same bit won't work
[Galaxy Tab 4 Original Android Development] engine95:
It doesn't make sense. I'm taking a break on it now. I bet I've spent more than 20hrs working on it and I'm no further than when I started.

It's got to be just the shader. But to even just change that kills other GPU. There's just no rhyme or reason.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I've noticed a few differences between the pxa 1088 board and the pxa 1l88 I'm going to se if that will make a difference. I seen a file (I got to find it again) that show things the pxa 1088 don't have like shader support (unless added in menuconfig) built in so I'm wanna see if it helps with our issue oh and there is a few differences that look promising so I'm just gonna give it a shot
[Galaxy Tab 4 Original Android Development] The_Anomalist:
No go

Well I've built the kernel as if it were a pxa 1l88 and it don't even finish compiling so that no good but there is some light at the end of the tunnel. There are 3 rails that have a set base frequency and increasing each past a certain frequency allows for more steps to be added but what's weird is the max stock frequency is 1482 which I change each time so I can use that freq as a common freq so it shows up but now I got it to were I can literally add frequencies ranging from 52 all the way up to 1586 which is awesome but its not really needed unless u would like for it to implemented into the build. I'm working on CPU more than GPU cuz the overall performance of the tab will be faster as many people don't use it for gaming and that I'm much closer to cracking the CPU than I am GPU. [MENTION=1280108]engine95[/MENTION] is way closer on that part than me plus working on separate tasks gives us both the opportunity to get 2 things done at once. I'm so sorry its taking way to long for a "perfect" build, I'm not stopping and I hope u guys feel the same :)
[Galaxy Tab 4 Original Android Development] doctazz:
beany23, go ahead and release a new kernel with 1586 when you can! That speed bump still helps a lot of games run smoother. As long as it's relatively stable, I'd love to try it. It's also great that you can add lower frequencies, as that helps save battery when the Tab 4 is idle for long periods. Please let us know when you have a new release. :)
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I will be working on it today so let's see what I can shell out
[Galaxy Tab 4 Original Android Development] theroadrunner:
Sorry if it's somewhere else in the 24 pages but I lost the IR blaster with the kernel. The blaster was iffy anyway and had to be restarted on occasion with the stock kernel
[Galaxy Tab 4 Original Android Development] CTXz:
This is because the kernel is based on the t230 edition instead of the NU version.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
sorry bout that

ok so i did as promised but left town for work for a few days so i couldnt post the build, but here it is underclock down to 56 and max overclock is 1586. enjoy!

http://www.mediafire.com/download/ex22xvztb3m7ldy/4.0.zip
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I noticed that the lag is due to lower frequencies which is related to the dvfs in dvfs pxa1088.c I'll see if I can fix it
[Galaxy Tab 4 Original Android Development] doctazz:
I'll give it a try. To alleviate the lag in the lower frequencies, try limiting the the low end to 156 or higher. Just a guess. Use Kernel Toolkit or some other CPU control app to do this. Might hold off until after Thanksgiving dinner/cleanup though! :)
[Galaxy Tab 4 Original Android Development] doctazz:
OK. Just tried it as the ham's not ready yet! :) Yep, definitely a laggy kernel. Tried various settings, including setting the governor to ondemand. Even tried performance... No luck keeping it as fast and responsive as the 1482 kernel. :( Back on that one right now.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
thank u for the feedback I will try limiting the min freq to 156 to see if it helps with the lag also dropped down from 1586 back to 1482 to see if that is also part of it. while iI think about it I might have missed adding into the voltage table as well
[Galaxy Tab 4 Original Android Development] The_Anomalist:
might be getting somewhere [MENTION=4623568]doctazz[/MENTION] I found out that the source u found has the pxa 1l88 defconfig file but when I try to build iit shows that theree is something with the battery files that keeps it from building. once I get it to build more than likely shader support will be added that's y it shows up as zero when looking at it but once the pxa 1l88 is built it should show up ( theoretically). and one more thing plz help me find out which pll's the GPU is running off of as well as what rail it depends on.

[Galaxy Tab 4 Original Android Development] Justray:
Thanks a lot to all who made this possible!

So far so great, this little device sure needed some boost I use it manly to write/read and emulators. All ran well but PSone, at native resolution runs smoothly but at 720 HD graphics this device just can't handle the awesome. Now it behaves waaay better but still need to thinker some GPU OC.

Thanks for making this device last an extra year before updating!
[Galaxy Tab 4 Original Android Development] The_Anomalist:
yessssss!

ok first of im sorry i havent been online lately been really busy and well i have done it gpu overclock to 832! but as [MENTION=4623568]doctazz[/MENTION] said it wipes out all other clock except 1066 and 1344 and all of the gpu clocks except 624 and 832 which i have really good hunch its because of what PLL they all run on. also i tried antutu even though it was laggy and holy crap! the graphics shot up tremendously. im feeling mighty confident that we might see close to 1 GHZ for the gpu! the reason being is that i didnt alter nothing related to voltage for the gpu so changing it slightly would be enough thats why i say 1 ghz. im very close and now have the confidence again to show the true power of this tab.

---------- Post added at 02:01 AM ---------- Previous post was at 01:43 AM ----------

this is so u can get an idea of what its capable of. it will be a little laggy but u can run dead trigger or antutu to see the graphics detail, which will be laggy but u can noticeably see the difference in quality. p.s. dead trigger dont run to bad either.

[Galaxy Tab 4 Original Android Development] doctazz:
Tried it last night (1/1) and it was laggy. Tested it with several games, including Looney Tunes Dash and Revolt classic. The games ran slower than the standard or 1482 kernel.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Ya that was expected it was just to see a look a the difference in graphics also if u want check under sys/device/platform/galcore to see what the GPU max is

---------- Post added at 06:26 PM ---------- Previous post was at 06:14 PM ----------

That's weird because 416 should not be showing because all clocks for wiped out except for 624 and 832 on GPU and all clocks on the CPU except 1066 and 1344. the kernel I just posted was to give u a taste of whats to come.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
This is frustrating. I can't seem figure out why the clocks dissapear, I've tried switching pll's but it still doesn't show up and the fact that it should work even as is. I tried 7 builds today with no positive results. Clocks still don't show up and max doesn't appear now. I could use help finding out which Pll will work. There is a few to work with pll-624, pll2, and pll2p. The pll2 and pll2p are also running the 1066 but yet again wipes out the clock. I need help plz so we can make this one monster of a tab. I seen a tablet over clock kernel for a device (forgot device) with GPU over clocked all the way to 984! This is something I wanna see but I need help.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Hello fellow members I got bad news. My computer crashed while building the latest kernel and it now doesn't even want to turn on nor does it make any sounds. effin blows cuz now development will be at a standstill :(
[Galaxy Tab 4 Original Android Development] doctazz:
OUCH!! :( Hope someone can step in and give you a PC to work with. Have you made any progress with the GPU overclocking?
[Galaxy Tab 4 Original Android Development] The_Anomalist:
I hope so I have a friend with a computer that he is willing to let me have but I gotta see if its even capable of building. And yes I have, I noticed the pll1-416 clock will not handle that frequency at which I set the 832 step. But when I try using pll-624 step and increase it I get clock wipes for all that run on that pll. The gpu clock doesn't show up still which sucks but what I've noticed so far is that even when trying to switch gpu freq it does work even though the clock shows "0" for all the freqs steps. Now I need to find the code related to showing the gpu clocks which is going to be hard because of the fact that anything could be causing it to not show up. It could be "userspace" or it could be "sysfs" I'm not sure yet.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
OK finally got a new computer. Will start building tomorrow since I have to configure things to my liking.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Guess I'll start some builds today since I configured things faster than I thought. If someone can do me a favor and try to find devices where the gpu don't show up so I can see if I can try the same strategy as they did so I can try to get the gpu to show up. [MENTION=4932679]decimalman[/MENTION] said that the gpu freqs should show up but not where apps expect them so maybe it's just a couple lines of code hopefully.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Anyone got any ideas for governors? Added freelunch and asswax governors from decimalmans dkp kernel
[Galaxy Tab 4 Original Android Development] The_Anomalist:
There's a few things I can do to show gpu freqs and I'm now currently building kernel adituor so it knows where to find the frequencies also I need to add some attributes to kobject so different kernel tuning apps can also find it.
[Galaxy Tab 4 Original Android Development] The_Anomalist:
Does anyone here have experience with Android studio? I'm trying to also build device control since it show the gpu section which would make it easier but I keep getting build errors. Kernel adituor builds just fine but has a more Complex interface.

Not really since it use a completely different processor so things are a bit difficult. As far as I know I'm the only one working on the kernel and development is at a stand still since cm doesn't really work to well with the tab :(.

I wish there was man but this tab is very very very difficult to work with that's y ppl decide to stop working on it but me well I can't give up not yet this was my first ever kernel and I can't leave a project unfinished but I'm trying and I will succeed just in due time.

---------- Post added at 06:46 PM ---------- Previous post was at 06:36 PM ----------

Unfortunately that kernel is fairly stock and uses the same frequency as ctx's kernel so it's not that different
[Galaxy Tab 4 Original Android Development] fen_nyc:
Beany, if you believe you've reached the performance threshold then don't burn yourself out- particularly since this tab isn't too popular (I still don't regret buying it) & your progress has already swallowed a PC. We appreciate your persistence & releases thus far! :good:

[MENTION=6584695]CTXz[/MENTION], thank you for the kernel tweak! I flashed 4.0 with no issues however, on the Settings > General > About Device... the kernel is listed as "3.10.0+"

Is this correct?
[Galaxy Tab 4 Original Android Development] CTXz:
The 3.10 is the linux kernel version where mine is only a numaration for my builds
[Galaxy Tab 4 Original Android Development] The_Anomalist:
The thing is that I haven't even come close to even topping out this kernel there is still a lot of things that can be added like more freq steps,inteliplugs,gpu overclock and whole bunch of other things but what makes it hard is that it doesn't use a snapdragon board or an enxyos, so it's quite difficult. The performance threshold I believe is not even close to being topped off. I could easily further overclock the CPU but ppl want gpu overclock and be able to show the gpu's frequency steps but it's just not easy. I cannot simply stop I'm must finish this thing. I WILL NOT QUIT.

[Galaxy Tab 4 Original Android Development] johnnyb47:
So I think I bricked the tablet (SM-T230NU). Flashed the 4.0 version of the kernel, along with Prism Barebone ROM. On first system boot Android would start "optimizing apps", but would reset after the 8th-9th app and start over from where it left. After all apps were optimized, the tab keeps playing the boot animation for hours until the battery dies.

Also tried installing the Acheron ROM, and the default kernel linked in the original post of this thread (via TWRP), then downloaded the latest SamMobile version and flashed it with Odin. No luck, though, the tab does the same thing at every reinstall.

Any ideas?
