Custom kernel for M6Pro

[maakie]

If anyone wants to try this custom kernel for M6Pro, I'd be interrested in any feedback. Most things should work. It is for KitKat ROMs only.

Edit: Now with working GPS.

Features:


* Patched to 3.0.101
* Overclocked
* Voltage control (Set CPU voltage from SetCPU etc.)
* Dynamic FSYNC
* Added ROW scheduler
* Added Hotplug governor
* etc.

The CPU table is bigger than stock (1 entry more) and has too high voltage for 1.6 and 1.7 Ghz. The RAM table is no more visible with my patching tool.
What is "Row scheduler"?

I assume it will work for 1.7 and 1.8 roms even if your kernel is 2Mb smaller than the stock one...

ROW scheduler is an IO scheduler that favors read over write. It can be selected with apps such as SetCPU. I have used the kernel with RR 1.8. The smaller size is probably due to a smaller boot logo.

what about RAM frequency/voltage?
Why is no more visible on table 8 with overclockomatic script?

Rockchip has changed some values in the DDR freq/volt tables which makes overclockomatic not find it.

Not true for M6pro kernel!!!
Also on RileROM 1.8 stock kernel RAM Freq/volt are still visible.

Now I modded the script to see ram tables, that on your kernel is:
== Table 8 at offset 9322420 ==
MHz mV
200 925 1 DDR_FREQ_SUSPEND
300 975 2 DDR_FREQ_VIDEO
400 1100
500 1150
600 1200
700 1250
800 1300 256 DDR_FREQ_NORMAL


== Table 9 at offset 9322484 ==
MHz mV
200 950 1 DDR_FREQ_SUSPEND
460 1150 256 DDR_FREQ_NORMAL



BUT ON STOCK KERNEL IS:

== Table 8 at offset 10212716 ==
MHz mV
580 1300 1 DDR_FREQ_NORMAL

Did you use a stock kernel for M6pro to prepare your modded one?

The M6Pro stock kernel is built from older source code. I think it would be quite easy to modify the overclockomatic script to find the tables.

Iìm testing your kernel and I made some mod to reduce power drain.
I removed also 1.6Ghz (on my mod I left 1.4 and 1.7 and removed 1.6Ghz).
I set ram to [email protected] instead of [email protected]

The splash screen is really beautiful!

All seems working properly now.
I'm having some trouble with GPS though...

Question on Performance

Hello - Did you run an ANttu? What did you get?

Thanks

Antutu results are identical or a little bit less than my mod kernels (about 21.000 points).
I need to test a little bit more this kernel about battery duration I switched CPU governor to "hotplug" to make a more significant test.

The worst thing is that GPS is less sensitive (tested on 2 different pipo m6pro)

I've have updated the first post with a new version which has GPS working better.

[giouncino]

very good.
I will perform testing soon!

Giouncino, are you compiling kernels now?

[giouncino]

not yet unfortunately...
I still can only do some minor mods...

[rrileypm]

I was just trying to figure out what you are doing to improve GPS. By just adjusting voltages...or have you found a patch? Just PM me if you don't want to answer here.
