So... Anyone out there played with /vendor/etc/perf-profile*.conf yet?
It appears we have 8 perfd profiles that something selects... And overrides any other CPU choices while perfd is enabled...
Thoughts?

I don't think I've ever bumped into the thermal.config...
I think perfd get a hold of the processor long before the thermal engine fires up

I think it uses both.
Definitely the thermal-engine.conf for heat throttling.
But the perf-profile is probably used and from what I can tell scaling up/down based on demand.
I modified them to take advantage of the overclock in my ElementalX kernel and tweaks thermal-engine.conf.
I now see the CPU go into the overclock frequencies more often. I hadn't even bothered looking in those files.
Great Find!!!!

There are some target loads. There are some ramp times.
If you are running ElementalX and are over clocked. Just adjust the frequencies to get the performance.
If you research thermal-engine.conf it will help understand these files.
Anyone out there know an 835 that has perfd that we could compare profiles?
I can't leave stuff alone...

Moin,
Is there any app that provides performance profiles like CPU-, GPU-clock speed etc? My old tf300 came with build in options for that :crying:

I mean something like a widget with Performance presets (yeah i should have said that ) so you can easily switch between them... for example
Code:
preset 1: CPU 1,5GHz to 1 GHz, GPU 400 MHz
preset 2: CPU 1 GHz to 380 MHz, GPU 200 MHz
etc.
franco.Kernel updater offers power modi based on which app you are currently running. It's not exactly what you were looking for, but I think this functionallity goes even further.
Also I think (I haven't used it in ~2 years) setCPU does offer some functionallity like this
Now that I understand the question: Is this even possible when we're talking stock/unrooted? (Just assuming, because OP asked for an app, not ROM)

No. Such a modification would need root access.
Thanks a lot! I will try SetCPU, because i don't want to manage the clockspeed for all of my apps in franco.updater
So I was wondering about the truth behind the risks of frying your cpu through overclocking or the chip itself degrading faster over time, and if there are such risks do they apply to a simple 2.5 ghz overclocking ?
There isn't any risk like that, unless you are using extremely high voltage, or are at terribly hot place.
I have tested all the overclockable kernels, and haven't found a single one which is steady at 2.6 or 2.8 GHz. Only Faux's kernel at 2490 MHz is stable.
Don't be scared, there's no risk.
PS: I personally use Performance governor by the way, so the CPU is always at max frequency, against all advice I keep using that for past three years, never had a problem, and you can understand where I live the temperature reaches extremely high in summer, so...

Now if you want more then flash one of those 2.6 or 2.8 GHz kernels, and do the test, and message me if Antutu finishes the benchmark even once

If you want higher you should try out Ultimate Kernel. Although it is removed from XDA, you can still find it on some foreign language site. It's the highest and most stable OC kernel I have used (3.0GHz).

Thanks a lot for the link mate. Downloaded and flashed v73, but I can't get it past the stock clock rate of 2265 MHz! I mean I have tried to set higher frequency than that in S Tweaks, even downloaded Trickstar, SetCPU, but the it'd just stuck at 2265 MHz! I can go lower than 2265 but not higher! Weird!

I think it comes with 2 apps for customization. You apply frequency on the first one and open the other and select apply changes. I'm not sure if it was this kernel or was it AEL. Lol. Anyways good luck. Maybe your ROM doesn't support a certain "stuff". I'm sorry but I really forgot about those terminologies. You can read up on the closed thread if you want. I'm sure you'll have a clue or on that link I gave you. *Google Translate ftw*
It is simple, tested on my nexus 6, just go to system/bin and delete mpdecision, then install an app that controls kernel, like kernel adiutor, raise min freq of cpu to 883000 mhz, then set apply on boot, reboot phone and enjoy lagfree and smooth super battery life

Disabling in a kernel app will accomplish the same thing. The reason you are seeing a change in battery life is because of the 3 second input boost of MPD. Most of the custom kernels have a generic touch boost driver that is set to 1 second or less to take the place of the mpd boost and increase battery because of the decreased boost time.
MPD works great for some people and not for others. It is greatly dependent on your usage habits. For my typical usage, with mpd on, I average 6-7 hours of screen on time. If you are a gamer, where you are constantly touching the screen, mpd will adversely affect your battery life because of the constant boost.
As a kernel developer, I definitely would not recommend deleting the mpd binary. I would suggest trying a couple of different kernels and/or configurations to accomplish the same results.
lol.. seriously? i guess thats one reason that ive disabled mpdecision for the last 3+ years on whichever nexus i was on, but not the main reason
How can I turn mpd off on ex kernel manager
you don't need a kernel app to disable it BTW. all kernel apps do is provide a ui for you to use. it can be done via a terminal emulator app.. type,
su(press enter)
stop mpdecision(press enter)
and that's it.
I'm using kernel auditor and in the CPU hotplug section the first listing is mp decision. Is that what needs to be disabled?
OK, silly question.. do you know what mpdecision does? do you know what disabling mpdecision does?

@simms22 good point here. This is good for everyone to know. If you disable mpd without a replacement, you risk all cores not coming back online after deep sleep. Mpd doesn't actually control hotplugging, it controls input boost and onlining of cores.

and that's exactly why I disable mpdecision, so I can have all 4 cores active at all times.

A replacement such as Zen, Mako, Blu_Plug, etc.
Also, (just an FIY) Zen isn't really a hotplug (it keeps all four cores active at all times, unlike Mako, Blu_Plug, etc). It's still lumped in there for some reason.
I highly recommend disabling MPDecision. You know what MPDecision stands for, right? MakePoor Decisions

Some kernels come with it already removed. Check the features section of the original post in the Elemental X thread or try searching the thread.
I can say from experience that Kernel Auditor doesn't give you access to all of the adjustments in Elemental X. Some features are only accessible through the official Elemental X app, so it might be there, but you can't use Kernel Auditor to adjust it.

The way the clock frequencies are done on this phone, the kernel has no control to overclock.
I asked the developer of ElementalX and also checked to see if thermal-engine existed.
No dice. No overclock.
Only GPU overclocking
So there in no known method of overclocking either Snap 845 or 855 CPUs, right? (i mean throgh software/kernel)
I've never seen the point of overclocking especially with latest chipsets

Is not possible, the CPU frequency tables are stored inside something called "TrustZone", basically the bootloader, and no one outside of Qualcomm has the ability and the tools to control or make changes in that area of the processor.

This means not only that we can not overclock (and this must also mean voltage table is ..off the table), but also we can not "set" a certain min/max frequency, right? Let's say i want to have a min/max of 2.8 ghz, it can't be done through kernel

Actually you can. It requires a Kernel that supports Overclocking. As of now there is no Kernel for the 6T that supports CPU Overclocking. Smurf has GPU OC but not CPU. Besides, the 845 is already a beast so I dunno why would you want to OC
I think me and more features will be driven by the chipsets themselves and will use a Trust Zone not accessible from the kernel (like widevine).
What is sure is that many CPU clock parameters are not accessible, that's why only GPU OC is present. This have been discussed in different kernel threads.
And the real question is why OC on those fast CPU, just to empty faster the battery and warm the phone in winter?

Isn't related to root or unroot, It's a limitation set at a lower level, lower than the operating system or the kernel.
You can modify the ramdisk to set the Max/Min frequencies, but those values must be within the stock values of the processor, I mean, you can't create a new frequency, you should use one that already exists.

Oh, so min/max can be adjusted? That's something at least. Sometimes the CPU assesses wrongly the speed needed to properly run an app (a very CPU heavy one) so restricting the CPU to lower the frequency provides the best performence possible on that hardware.
And yes even a powerful Soc like 845 and even 855 are pushed to the limits by certain apps.

Yes and no, OOS applies boosts from the userspace, I mean that although you limit the frequency of the processor, in certain circumstances that limit can "break" (I don't use custom roms on this device, so I don't know about it, but probably the same thing happens).
This is interesting. I want to look. Into tz and see what I can find
