I've searched the Legend subforum for setcpu and have come up with nothing relevant so here goes..
I'm looking for Legend-only SetCPU profile suggestions. I've found quite a few other forums with their own device specific profiles posted and I'm almost positive I cannot be the only other Legend & SetCPU user here.
Any suggestions would be appreciated!
I want to know too
I use these profiles;
Charging/Full 600/600 performance
Screen-off 480/122 userspace

But this is just downclocking because the legend default processor frecquency is 600MHz.¿¿How can we overclock the processor to i.e. 800MHZ??
I take no credit of these codes. All i did is create a patch against with the leo kernel tree.
cpufreq: interactive: New 'interactive' governor
New interactive governor.
This governor is designed for latency sensitive workloads, UI interaction for
example.
Advantages:
+ significantly more responsive to ramp cpu up when required (UI interaction)
+ more consistent ramping, existing governors do their cpu load sampling in a
workqueue context, the 'interactive' governor does this in a timer context, which
gives more consistent cpu load sampling.
+ higher priority for cpu frequency increase, rt_workqueue is used for scaling
up, giving the remaining tasks the cpu performance benefit, unlike existing
governors which schedule rampup work to occur after your performance starved
tasks have completed.
Existing governors sample cpu load at a particular rate, typically
every X ms. Which can lead to under powering UI threads when the user has
interacted with an idle system until the next sample period happns.
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down
to.
There is only one tuneable for this governor:
/sys/devices/system/cpu/cpufreq/interactive/min_sample_rate:
The minimum ammount of time to spend at the current frequency before
ramping down. This is to ensure that the governor has seen enough
historic cpu load data to determine the appropriate workload.
Default is 5000 uS.

2.6.32-sched-bfs-318.patch.zip: is the patch is downloaded from official BFS site.
oc_uv_ab.patch.zip : this patch includes under volt, overclocking (upto 1.3GHz, any frequency above 1.15G is unstable on some of HD2s) and audio boost.
how does it work?
Sounds great. Maybe someone can integrate this into a kernel?
thanks for this!!
How to apply patch
I could really use the audio boost. Is there anyway you could explain how to apply the patches. Or is it possible you could apply them and post the patched kernel files? Thanks.
Would this actually have an improving effect on the touchscreen being unresponsive from time to time?
Hello,
Would it be possible to add the newer versions for oc_uv_ab.patch and interactive governor or I just don't know how to use GIT to well?
I don't have too much experience with C++, PHP dev here , and I'd like to compile my own kernel from the official GIT + change the MAC of the build to my own HD MAC + maybe some other small changes (adjust max freq and such).
Thank you very much for your hard work.
Kind regards.

Introduction
This is a kernel for XT1572/XT1575 built from stock sources (marshmallow-6.0.0-release branch) with cherry picks from other kernels and some ports/mods done by me. It started as a personal build tailored to my preferences but just thought I'd share in case somebody might find it useful. My main goal is building the smoothest kernel I can get so performance is top priority.
This kernel is for stock ROM MPH24.49-18*
Disclaimer
Although I have experience with Linux kernels on desktops and servers this is my first Android kernel. I've been running this kernel on my XT1572 for a few days and seems pretty stable but that doesn't mean it's risk free. In fact I wouldn't dare to install it if you don't have a proper backup and some basic skills to deal with unexpected situations.

Donations
Although quite a deal of the important work has been done by the developers mentioned in the Credits section I spend many hours working on this. If you feel like helping me out I'd appreciate some tiny donations to cover some minor expenses.
Thanks to all of you who have donated, it's very much appreciated.
Profiles
One of the FAQ in most kernel related threads is "What are the best settings for .....?". This is the 10 million question since the usage pattern can be very different for each user. However, I understand less experienced users will appreciate some hints in this department, so that's why I'm posting some basic settings you can use as a starting point.
It's your job to further tune them to suit your needs. You should be able to modify these settings with whatever Kernel Control App you like the best, although not all settings are available in every app, in such a case tune those you can. The list is not complete (just the most importante settings) and is loosely based on Kernel Adiutor arrangement.
Please, keep in mind these are subjective values (based of personal preferences or popularity) and some people might like other settings for whatever reasons.

FAQ
I get random reboots, what is happening?
This kernel overclocks both clusters by default (a53: 1536MHz a57:2016MHz) and although this is very safe for most devices some CPUs are in the lowest spot of the binning spectrum and can't handle O/C very well. In such a case use a kernel control app (see the OP for references) to limit the maximum CPU frequencies, play with them until you find stable values for your device.
What are the best settings for battery life/performance/whatever?
That's hard to tell as every user is different. You can find some basic profiles in the OP you can use as a starting point. Notice the differences between then and build you own.
Why do some BIG cluster settings display N/A?
Why can't I change some settings on the BIG cluster?
If you get N/A or weird values when trying to change settings on BIG cores it means both are offline ("hotunplugged"). To work around this select "performance" governor, make your desired changes and then select you previous governor. You can also disable hotplug, make the changes, and enable hotplug again.
DoubleTap2Wake doesn't work sometimes. How can I get it to work all the time?
When device goes into suspend mode first tap is often missed (I suspect this is caused by Moto Sensor Hub). If you tap three times and get the timing right you'll probably make it work most of the time. As an alternative, Sweep2Wake works almost all the time
DT2W/S2W is acting weird or disabling itself
Make sure Moto Display is disabled. Open the Moto app, click on the stars in the top right corner, select Display and set to Off
Can I use this kernel in ROM X/Y/Z?
This is for stock ROM MPH24.49-18 only. It'll probably work on any stock based ROM but not guaranteed.
I use stock ROM but WiFi is not working
Due to some internal changes all modules had to be recompiled (WiFi included). In order to expose the new modules without modifying the system partition I had to implement a hack that requires root. Make sure you're properly rooted.
What's the deal with ZRAM?
ZRAM is a technique to increase memory available to the apps at the expense of CPU time. Memory space from apps not being used is compressed into a memory swap area and uncompressed on the fly whenever needed. As you can imagine this compress/uncompress process burns CPU cycles, potentially leading to worse battery life, lag and higher temperatures. Since this device comes with 3GB I can only think of one scenario where ZRAM can be beneficial: heavy multitaskers who care more about apps not reloading than battery life. For the rest of users enabling ZRAM doesn't make much sense in my opinion, and that's why it's disabled by default.
UPDATE: v0.10 includes an updated ZRAM driver that improves performance significantly. So much so that the benefits seem to outweigh the costs and it's been enabled by default.
What's the deal with KSM/UKSM?
Since many apps use the same libraries/resources it's very likely that at any given time there are multiple copies of the same data on different memory locations. KSM/UKSM tries to take advantage of that fact by scanning memory pages periodically and consolidating that multiple copies into a single shared copy. Much as like ZRAM it can have a good effect on heavy multitasking performance but at the expense of CPU cycles, and thus it's only recommended in the same scenario as ZRAM. Disabled by default
Ok, so do I enable ZRAM/KSM/both/neither?
I honestly think most users will be better off not using neither. If you feel like you need extra RAM I'd try KSM first, then ZRAM. Using both at the same time is overkill unless you are an ultra multitasker, in which case you should probably get a 4GB device anyway
How do I get WiFi on 6.0.1?
It's a modem version mismatch issue, you need to downgrade the modem. See this post.
Love to see more options! Thanks for sharing!!
Yeah this will be very good
Only One think that would be awesome try to implement the double tap to wake
Awesome! More custom kernels are always welcome are there many governors to choose from?

As I said on the OP my main goal is performance/smoothness, so I haven't specifically sought better battery life. That being said I'm getting about the same battery life as stock with better performance, that works for me.
Nevertheless, I'm very interested on how it works for other configurations and usage patterns.
@dirtyhank could you please add hotplugging to the kernel? Preferably one that allows you to select how many cores to run as well as which ones, as in run the two A57s and turn off the four A53s. Currently I'm running two A53s at 1.2Ghz and the remaining four cores are always off.
The screenshot is from Lolipop, and it is the only reason why I havent upgraded to MM. Turning off cores definitely makes a difference on battery life.
Also, if possible, adding a lower speed to the min speed. Will gladly test anything you thow my way. Thanks in advance.
Is there any chance for a CM13 version and a DT2W fork from elementalx?

Getting bootloop on TruePure rom 2.4. Anything I can try to avoid bootloops?
So I've been hearing Schedutil is the most balanced governor for Android phones cause it can handle battery and performance well.I searched it on internet and found some article about it that my brain can't understand.
Why is it better and how it works? Can anybody explain it to me or provide me some link where I can read about it?
Thank You
It's a CPU governor. Look inside here. This governor requires Linux kernel 4.7+.
I got problem with schedutil on oneplus 9, its the default governor and get low fps while gaming. Maybe is a bug with "games" app what should change to a better governor while gaming... it also have a "performance" option
This governor is quiet ****. Its like ondemand ramping up to max clock when not needed.
