Binary patched kernels for Pipo models

[rceccleston]

rceccleston , these results are simply put : AWESOME for a tablet of this price range !!!
If ur tablet is stable and fluent, batt drain is ok and temp is ok , then i would smile from here to the moon i think

Your are welcome to flash the kernels I have posted.

All kernels have successfully produced Antutu scores and passed the Antutu stability test.

My M6 has been more stable at these higher clock speeds, due to a better power supply, than my CX-919 clocked at [email protected] GPU@800Mhz RAM@DDR800.

I have an 8 amp power supply on route for my CX-919

I own a M6Pro so is it even possible to use ur kernel ?


giouncino : I'm going to install the 1.7/600/720 Low voltage now and do some tests.

No, You can't install a kernel for M6 not pro.

I'm curious about stability on your tablet of my low voltage kernel! Thank you!

PS: I think that stock GPU voltages are too high (based on my early tests lowering GPU voltages)

Antutu : 19038
RAM speed : 1051 ( i dont get it anymore. Previous test with 1.7/600/720 was 1116)
Stab test : ok , graph between 90 and 85 but between 30 and 35 a jump from 90 to 80 and back to 87, thats not so good....
Nenamark 2 : 54.1 fps

very good, so can be considered generally stable. You're probaly at the lower limit for your freq/voltage. Try using it for a while (if you want), I think you can see the decrease of battery consumption.
a drop of up to 200-250 points (total) I think can be considered normal and due to interference of other Android or apps processes still running. So I don't think you have to be worried on a drop of 65points for ram test.

If you run Antutu for five time you will have 5 different results!

The voltages itself, as far as I know, couldn't be responsible for performance drop: if there is something wrong the benchmark crashes or the test is aborted.

I found disabling the WiFi connection helps produce more consistent results.

kernel m7pro?

hey guys..

first of all i really appreciate your work here. this is way too complicated for me.
i have an m7pro using rileyrom 2.1.1

is it possible to swap the configuration of your m6(pro) kernel to a m7pro kernel?

i am dreaming of antutu showing me a 20000+ :-)

shall i upload the stock kernel for you?

Re: Binary patched kernels for Pipo models

I'm pretty sure I included one of these kernels in my ROM. Check the RILEYROM in the kit.

[herrjemineh]

There is no working kernel with more than stock cpu clock..

Am Ende ist alles gut, und wenn nicht alles gut ist, dann ist es auch nicht das Ende...

Giouncino,

Kernel 1.7/600/720 low voltage performs well :

Multiple tests on Antutu (at least 5 test on random usage time) :
HD mode : between 19300 and 19450
Normal mode : between 20140 and 20350

But : Antutu stability test : graph jumps arround between 90 an 75. Once I had a jump from 89 to 76. Now thats a deep dip ! Tablet did finish all the tests thow.
With the first 1.7/600/720 kernel with voltages at 1.375 CPU , 1.3 on RAM , Antutu scores are a tad higher (not significant and maybe have nothing to do with voltages) but the stability test are way flatter.
No more jumping between 90 and 75 but more between 90 and 80 and never a dip or jump higher than 5 points at a time.

One strange thing:
In normal mode with 1.7/600/720 low voltage kernel : Antutu stability test is WAY flatter.
Graph stays between 90 and 85 ! Also mem speed is up by 100 - 150 points.
What has the display mode to do with the mem speed or stability of the Antutu test ?

On both kernels, with my dialy work, no problem whatsoever !
All is working fluent and stable... for me, the 1.7/600/720 low voltage is already a winner kernel !

...but nothing app is crashed, and I think it's the most important thing.
I suppose that in normal use you will see at least a little bit improvement in battery duration...

I'm thinking to prepare as soon as possible (and obviously test) the profiles you can see in the attachment.
Tell me what you think.
SoC RK3188 Freq-Volt parameters preview.zip
My target is to have a ratio 1:2 between CPU and RAM, because on PC this kind of relation is one of the best. I can assume it is also valid for tablets.... I'll test it very soon.

I'm now testing the "GPU powersave" setup (with CPU in balanced mode), It seems stable but I haven't enough time to test it.
I'll probably need to increase GPU voltages a little bit to be really safe...(My wife is using the tablet now, and I cannot be sure if everything is really working well...)

I' think that as soon as these 3 releases are ready and a little bit tested, Randy could include them in the next "RileyRom editions". Isn't it Randy?

My antutu score now with the 1.7/600/720 low voltage is already in the range of 19300-19450 so i'm not entirely shure that your balanced profile with 1.7/666/852 is only going to hit an estimated of 19300.
Why the RAM so high ? Isnt that a bit too high for the specs of the RAM?
I also tested you previously posted [email protected]/600/[email protected] kernel but it didnt complete the Antutu test and even frooze my tablet....3x in a row..so thats a no go for me.

Ok, I missed that point. But I'm not sure what froze your tablet: CPU or RAM (i think the RAM, because the CPU with so high voltage is generally stable...)

Probably you're right about the RAM frequency...
I'll give you news as soon as I'll get my hands again on my tablet!

Hello giouncino

I ve flashed your low voltage kernel but it doesn't start and freeze on bootlogo...

My CPU si not so lucky like yours!

I wait for your "Turbo" release that seems to have parameters I prefer the most.... :-)

Thanks for your great job!

Thank you Claudio,
I'll keep in mind your tablet's behaviour as soon as I'll release the 3 profiles: I think I'll release 3 more profiles with 25-50mV more on every frequencies, to allow "not lucky" tablets like yours to use my modified kernels profiles (keep in mind that even with 50mV more the CPU/GPU are still undervolted by at least 25mV, so it will be safe to use).

I'm now testing the "Balanced" profile with the following modifications:
I had to rise by +25mV the two lowest GPU frequencies (133Mhz and 200Mhz) to avoid rare little artifacts presentation.
I had to decrease memory frequency to 800Mhz/1.25V (I'll checheck if I can decrease RAM voltage a little bit more). At 852Mhz the tablet doesn't boot at all... My dream of 1:2 ratio between CPU and RAM is definitely broken...
I think it's important to decrease RAM voltage as much as I can because RAM remains ALWAYS at that fixed frequency: so, battery duration is affected irrespectively of tablet computational load. Ram power consumption as far as I kwon is nearly 500mW at rated speed/voltage.

My antutu score is now 19500points. I'm going to do other more tests today and then I'll go to test "turbo" mode (with RAM set to 800Mhz for the reason above).

With general use, all 3 profiles can increase battery duration.
