[KERNEL] M-Kernel [MOVED]
- Thread starter Metallice
- Start date
- Status
After some more tinkering, I've found that I could hit 600MHz gpu with a bit more voltage and gaming performance improves noticeably. I'm guessing that Franco's kernel must ramp up voltage automatically. I'll do some experimentation to find the lowest stable voltages for my N7, but anyone know of a thread where other folks have shared their settings?
Thanks,
PMS
-Can someone provide me with the default tuneable values from TouchDemand governor?
-Also I need the file under /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table
Thanks in advance.

Thanks in advance.
Correct. Unlike other kernels, m-kernel does not automatically raise the core voltage to pre-determined fixed values when you increase the GPU frequency. Instead I let you to set the GPU voltage yourself with TricksterMod.
Sorry Metallice, my enquiries are to set proper values for other device,
recently in a kernel for the one x, it was implemented the Touchdemand governor, and I wanted to know
some nice values for the governor knowing your kernel already has a good time with it.
Also, I asked for the UV table to know the default values that you are using for each cpu frequency, for test purpouse.
Well no duh this kernel has a good time with it. It's a modified ondemand governor that I made for this kernel and device.
Currently I have the TouchDemand defaults set to (going down the list in TricksterMod) - 5, off, on, 0, 2, 20000, on, 4, 475000, 1000, 0, 98.
Voltages
/* Cpu voltages (mV): ________800, 825, 850, 875, 900, 912, _ 975, 1000, 1025, 1050, 1075, 1100, 1125, 1150, 1175,
CPU_DVFS("cpu_g", 4, 2, MHZ, 550, 550, 770, 770, 910, 910, 1150, 1230, 1280, 1330, 1370, 1400, 1500, 1600, 1700),

Thanks! for the uv table,
Also, under touch min cores I put 2, also added 2 steps to touch floor freq, and downed threshold to 95. I think this will eat battery, but I'm getting an amazing UI speed that neither interactive can match...
But I want something from this, I wanted the governor to mantain touch_min_cores like "max" cores (like, use only 2 cores, no more than that!)... but if only 2 cores can't handle the threshold (Like if you open NFS, epic citadel, or MHL) just ramp it to max 4 cores, like if the governor worked as hotplug
What do you think about it?

Hey Metallice,
Just wondering how long does your battery last on your setup?

I dunno. I don't really obsess over that unless I'm specifically looking at it for tweaking touchdemand for example.
Hmm... looking at it today... 5hrs 6min screen on time, 30% left.
Working on a new OP for mr1... Finally got a simplified feature list/changelog... Need to clean it up some haha.
Probably forgot a lot of things too.

Re: [KERNEL][3G+WIFI][4.2.2] M-Kernel - a37
I'm guessing that's with the recommended settings?
P.S: Is this based off of Motley? So if Motley adds something (that somehow this doesn't have) it appears in this kernel?

No. And no it is not. It's exactly the same.

@Metallice
Are those the features for the upcoming a38? If so, then that's a HUGE improvement.

25650How would you guys feel about me closing this thread and starting a new one in Android Original Development? It technically belongs there anyway, and I wouldn't mind reserving a couple more posts in the beginning for a FAQ and other stuff. Hopefully to stop any more "Why is my min stuck at 340MHz?!?" and others like it36Working on a new OP for mr1... Finally got a simplified feature list/changelog... Need to clean it up some haha.

23Now, on to my status with this -
As a quick fix, I will revert this patch for the next build. This should hopefully solve all issues with a33 including, but not limited to, SODs, reboots, and increased battery drain in LP1 (too little voltage, but not little enough to cause freezes/reboots, has been shown to actually cause increased battery drain as compensation).
Unfortunately I haven't been able to whip up a quick fix for a couple reasons.
For one, I have other responsibilities. I had a Physics midterm early today and had to spend time reviewing and studying. Also, my father purchased a new HDTV (very nice one, super jealous) and I had to help him go pick it up and transport it, unpack it, remove the old, gigantic, heavy as f---, rear projection DLP HDTV, set up/secure/mount the new one, situate all the cables with the FIOS box/DVD/AV receiver/Surround sound, reprogram the universal remote, set up the new smart tv capabilities with the internet and their internet video services, update the TV software, set up the 3d and 3d glasses, and teach them all how to use the new stuff.
Second, my computer broke. The graphics card started acting up, kept getting messages about it failing and successfully restarting until it no longer would successfully restart. Tried uninstalling/reinstalling drivers and the whole kitchen sink, but the card was dead and there was no way around it. Aren't laptops with their all-fused components wonderful? To be honest four years is a decent run for a cheap 4-yo HP. Anyway, I need a computer for school so I got a new one as an early birthday present.
So I have a new computer now. First of all it's a macbook so I'm going to have to learn how to use OSX for one thing and get everything set up, and I'm going to have to re-make my kernel build environment from scratch which will take some time.
So hang tight please!
