I just spent some time doing some miscellaneous tweaks to the smartassv2 gov on the new Lionfish kernel. I am extrememly battery conscious with this tweaking as i will soon be giving this EVO to my father who has to rely on in for business. I followed the info in a few other threads and thought I had what i needed to make the correct changes so I made them. I've noticed that after the changes I've made, the cpu scaling seems to be rather erratic, meaning it never really settles at low frequency. I don't know if this is due to the stock setting of the gov as i didn't check the scaling before hand or if it has to do with my changes.
my current settings are as follows
768000= awake_ideal_freq;
245000= sleep_ideal_freq;
499200= sleep_wakeup_freq
85=max_cpu_load;
70=min_cpu_load;
38400= ramp_up_step;(left at stock)
38400= ramp_down_step;(left at stock)
10000= up_rate_us(left at Stock)
20000= down_rate_us(left at Stock)
I didn't touch the rampup/down of the scaling intervals or anything, so i don't really understand why this is happening. And sugestions out there?
shameful bump....
If you're running Sense I wouldn't recommend that low of a main clock, and honestly if your dad knows nothing of rooting I'd unroot it, leave everything stock, and let him fair with it, wouldn't want the device bugging out on him after all.
SavocaFTW is right, you are way under, just use on demand it will be just fine, if you set the evo values to low the system gets whacked out bad.
I've been using newest lionfish 1.2 and V6 supercharger with setting #8. Tried it just for kicks and its been working great for battery life. Use System Tuner Pro. Don't use Set CPU. I use ondemand 768-245. One other you thing to do is use a file manager to navigate to the system/etc folder and scroll down until you find the init.post_boot.sh file and either delete it or move it to your sd card. This is the cause of most of problems i'm sure.
Is it OK to run these two together? Will I lose the benefits of this kernel by running SetCPU? Will changing the governor affect anything?
Since the governors on classic are default, it should work the same...
Just remember using profiles has setcpu polling to see the status of your phone...so that does gave a draw on the phone, not much in the overall scheme of things, especially if you already use it, you are used to it.
The concern usually occurs if using custom governors, example Smartassv2 and a screen off profile in setcpu would be constantly fighting each other..negating any benefits of either.
I also do recommend since you're using SetCPU to manage your governors, frequencies, etc to move/delete the init.post_boot.sh file and the reasoning for this is because this file outlines several parameters for controlling your cpu at bootup and some of those settings include, a pre-determined governors polling intervals, up/down thresholds and min/max cpu frequencies so without deleting/moving this file and using SetCpu in conjunction with it, unstability can happen in the background due to your phone constantly going back and forward with itself because of too many apps/scripts telling it to do different things. Now if you're not going to use SetCPU I recommend not to touch this file. You can reference this Post
Good call.. I always forget to mention that file, I dropped using setcpu a long time ago, lol..
Welcome to decimalman's kernel playground!
As the name suggests, dkp is a hodgepodge of features and tweaks that I wanted to play with. It should get excellent battery life without feeling sluggish. It doesn't come with its own tuner app, so pick your favorite. Personally, I like Trickster MOD and Kernel Adiutor, so I go out of my way to make things work in them. Most other apps should work, too.
Features:
Overclocking up to 2.1 GHz, but you'll need to increase your voltages to get there (if you can get there at all)
Underclocking down to 54 MHz, with stability improvements
Undervolting compatible with most apps
Fast charge without unplugging first
Glorious animations for the notification and softkey LEDs
Well-integrated erandom means you don't need CrossBreeder or Seeder (recent AOSP builds use ISAAC instead)
freelunch and tierservative governors for optimal battery life without sacrificing responsiveness
Automatic mpdecision and auto-hotplug are only enabled when needed
Adjustable minimum voltage for stability on finicky processors
Optimized UKSM to free up some extra memory
Code optimizations for size and speed
Compiler optimizations (-O3, LTO, and more) because faster is better

Be silly. We're here to have fun.
Installation:
Reboot to recovery. I recommend that one recovery...you know, the one that flashes zips? I forget what it's called.
Flash dkp. Optionally, rename and flash dkp-vmin-XXX.zip (see below).
Reboot.
Undervolting:
Undervolting on dkp is more complex than other kernels. Some processors get unstable at lower voltages, so (like the stock kernel) dkp keeps the processor voltage above 1150 mV by default. I refer to this limit as the minimum voltage. In order to undervolt, you'll need to lower the minimum voltage: if you use Trickster MOD or Kernel Adiutor, just disable "Override Minimum Voltage", otherwise rename dkp-vmin-XXX.zip to e.g. dkp-vmin-600.zip (which would apply a 600 mV minimum voltage) and flash it. If this causes instability (crashes, audio/video glitches, etc.), try using dkp-vmin-XXX.zip to apply a higher minimum voltage (somewhere between 950 and 1050 mV seems to work well for most people).

Goodies:
dkp doesn't come with its own splash screen. However, the dkp installer (i.e. the install zip) is smarter than you think, and can apply a custom splash screen for you. Here's how:
Create a folder on your internal storage named "dkp"
Copy a PNG image into the directory, and rename it "splash.png". Alternatively, copy an RLE image (i.e. from a flashable custom splash screen zip) and rename it "splash.rle". Ideally, the image should be roughly 1280x720 to begin with, since it won't be resized.
The image will be used as your splash screen whenever you flash dkp. Reflash to apply initially.
mikedavis120 has put together a how-to video that covers tweaking dkp for optimal battery life. If you're new to dkp, take a look! He also put together a zipped collection of apps that will come in handy while tuning dkp. It also includes a flashable zip, "dkp-debug_v1.zip". After flashing it, running
Code:
su
dkp
from a terminal emulator will collect lots of useful debug information that will make it much easier for me to track down the issue you're having. :good: mikedavis120 recommends installing SuperSU (included in the zip) instead of what's included in you ROM.
sysfs:
It's possible to adjust all the settings available in dkp without using apps. Because they show up as files, settings can be adjusted with file managers, terminal emulators, adb and initscripts. Here's the most interesting files inside sysfs:
/sys/devices/platform/mipi_samsung_oled.513/lcd/panel/panel_colors (not available on newer AOSP builds): display tint (0 = very red, 2 = default, 4 = trinity colors)
/sys/class/misc/gammacontrol (only available on newer AOSP builds): various color controls. See this post for details on enabling Trinity colors on builds that use these controls.
/sys/devices/system/cpu/cpu<N>/cpufreq/UV_mV_table: voltage table
/sys/devices/system/cpu/cpu<N>/cpufreq/scaling_...: scaling_governor is the governor, scaling_min_freq and scaling_max_freq are the minimum and maximum frequencies, scaling_available_governors and scaling_available_frequencies show the available governors and frequencies
/sys/kernel/dkp/force_fast_charge: fast charge
/sys/kernel/dkp/link_core_settings: when linked (the default), frequency settings and some governors are automatically copied to the other core
/sys/kernel/dkp/vmin: minimum processor voltage in mV
/sys/kernel/mm/uksm/run: activate UKSM
auto-hotplug tuners:
These show up in the governor settings for any governor that doesn't do its own hotplugging. They only take effect when using auto-hotplug, so you'll probably need to disable mpdecision in Trickster.
hotplug_intpulse: when set to 1, automatically turns core 2 on whenever the screen/buttons/whatever is pressed. Default is 0.
hotplug_sampling_periods: number of samples to use for average number of running tasks. Default is 15.
hotplug_sampling_rate: number of 'jiffies' (currently 1 jiffy = 10 ms) between each sample of running tasks. Default is 20 (0.2 sec).
hotplug_enable_one_threshold: the average number of running tasks required to turn core 2 on, multiplied by 100. Default is 125 (1.25 tasks on average).
hotplug_disable_one_threshold: the average number of running tasks required to keep core 2 on, multiplied by 100. Default is 250 (2.5 tasks on average).
freelunch/nanolunch tuners:
freelunch and nanolunch aren't materially based on other governors, so their configuration is quite different than other governors. There's lots of tuners, since I haven't really decided on an ideal tuning. I encourage experimentation! I'll explain a bit of how these governors work before actually listing the tuners.
Generally speaking, there are two modes: in "normal" mode, sampling is done occasionally and frequency is generally increased slowly; in "interactive" mode, sampling is done much more quickly, and frequency increases much more quickly. "Interactive" mode ends after several samples of very low usage. The idea of a "hispeed" frequency is used in lots of governors, and it refers to the frequency that the CPU will jump to when more CPU usage is needed; generally, it's a generous estimate of how much CPU will be needed. Here, the hispeed frequency is adjusted on-the-fly, increasing when more CPU is needed and gradually decreasing when the CPU is idle. In "interactive" mode, the hispeed frequency is kept fairly high so that everything will feel snappy.
Hotplugging is taken care of in the least complicated (and in my opinion, most reasonable) way possible: if core 1 is using lots of CPU, and there are several tasks running (in other words, if it's likely that core 2 will have something to do), core 2 is turned on; if either core isn't doing much except using power, core 2 is turned off.
sampling_rate: the usual
hotplug_up_cycles: number of consecutive heavily-loaded samples before core 2 is turned on
hotplug_down_cycles: number of consecutive lightly-loaded samples before core 2 is turned off
hotplug_up_load: number of running tasks required to bring core 2 online
hotplug_up_usage: number of used CPU cycles (in thousands per second) required to bring core 2 online
hotplug_down_usage: number of used CPU cycles (in thousands per second) required on both cores to keep core 2 online
overestimate_khz: number of CPU cycles to overshoot usage by in "normal" mode
hispeed_thresh: if CPU usage is within this many cycles (in thousands per second) of the maximum frequency, frequency will be increased to the hispeed frequency. Generally, hispeed is pretty low in "normal" mode, and fairly high in "interactive" mode.
hispeed_decrease: when the CPU is sitting idle, the hispeed frequency is decreased by this amount each sample (this isn't ideal, but it works)
interaction_hispeed: the initial hispeed frequency when switching to "interactive" mode
interaction_return_cycles: number of consecutive lightly-loaded samples before returning to "normal" mode
interaction_return_usage: number of used CPU cycles (in thousands per second) required to stay in "interactive" mode
interaction_panic (nanolunch only): when set to 1, allows aggressively jumping past the current hispeed frequency under some circumstances
interaction_sampling_rate/overestimate_khz: equivalent to the "normal" versions of the tuners, these take effect in "interactive" mode

Is it possible they are left over from a previous kernel? Because I can def tell the difference usually and seems like it does.
Either way, advise when its updated. This governor seems solid so far.

dkp is based off clean CM source, so it shouldn't have been merged already.
I've got test builds compiling now, and the 3.4 builds will be up shortly. Flashing the trinity-colors test build and this zip will enable trinity colors. You can toggle it with
Code:
su
echo X >/sys/class/mdnie/mdnie/trinity_colors
where X is 0 to disable or 1 to enable.
Edit: and sorry for taking so long to respond.
Edit 2: 3.4 builds are up. http://d-h.st/7Ae
Thnx for this kernel

Maybe I was just seeing things, had just watched jurassic park in 3d.
New "test" build flashed as well as the file to enable it. Thanks for the addition. It's very hard to go back to normal once you've been smurfed depending on your display.
Only issue i'm having ATM is the ability to change the voltage table. My phone doesn't handle undervolting as well and i run a minimum of 950 baseline, if not 975. One of my normal apps wasn't able to set the voltage at all. I'm trying to use performance control which I don't like. It crashes trying to set the voltage on boot but at least I can go in and manually set the values on boot and they stick.
One last question, since this is your kernel, what scheduler do you recommend pairs well to freelunch? What would you use for performance and what would you use for batt?

Answered my own problem. I installed trickster as mentioned in OP and all voltage settings stick no problem with no issues.

Personally, I don't like trinity colors, but I definitely understand the appeal. I merged this into 3.0 and 3.4, so it'll be standard from here on. I'll add a link to the enabler zip in the OP as well.
What app would you normally use? I'll try to support it, since I already provide several voltage interfaces. I didn't realize performance control was crashing (I'm not a fan either, so I only lightly tested). I recently installed Trickster and liked it, so I've been going out of my way to support it. It's also really easy to write support for, so that's a bonus for me.
As for schedulers, I'm not fussy. I've never exhaustively tested performance and battery life, so I don't have a preference and usually run noop or deadline. However, I've had nothing but bad results with ROW (phone never deep sleeps, and I haven't looked into why).

good to know. Trickster mod works fine and you mention it in the OP and it's at no cost in the play store. I wouldn't worry.
I was using an app called kernel tuner because some others would only set 1 core to the governor and not both. I checked that trickster does indeed set both cores to freelunch so once that figured out I removed kernel tuner. Kernel Tuner also has the options for profiles which can be toggled in tasker for varies states. freelunch so far hasn't needed any changing so not worried about it at this point. just as an example, some governors would be better for screen on/off and tasker could switch these to edge out battery life.
The voltage app i was using is simply called voltage control. Kernel tuner doesn't do a nice job of voltage changes. But since trickster does both governor and voltage adjustments well. i'm using that with no problems now.
Thanks for the morfic, having a way to toggle it works well for people. it's as simple as a script so there's that.

I meant to test Voltage Control but Google wasn't letting me download anything. It's a common app, so I'll try to get it working regardless. Kernel Tuner doesn't currently work well with freelunch, and tends to hang when it's trying to read settings in the CPU screen. Otherwise, it's a nice app. I didn't realize it had Tasker support (I use Llama).
I've added a few extra bits to the cpufreq core, so governors that need to be set on both cores (like freelunch) will automatically apply to both cores regardless of what app is used. cpufreq will even enable and disable mpdecision depending on whether a hotplugging governor is running (though Trickster won't show that it's disabled).
I owe ktoonsez for the toggleable trinity colors. I slightly rewrote his patch, but it's still largely his code. It's my policy that anything that not all users will want should be optional and easily configurable.
Edit: I think I've got Voltage Control fixed. I should be able to get Kernel Tuner working without too much work. I haven't even looked into Performance Control yet.

well good job so far. batt life has been top notch. minimal drain in use and my over night idle drain was only a few %. I have things setup to disable wifi when sleep and also turn off mobile data when wifi is connected. A bit over the top but every bit helps.
:good::highfive:
I know I've been grilling you today but...
Kind of curious what the new tunables do. I haven't touched anything since it's working so well but there is always that part of me that wonders what adjust parameters will do. Is there any kind of reference for this governor that could indicate that type of info?
Does your kernel support faux sound app?

Yes. 3.0 and 3.4 both have support.
As for tuneables, I've been meaning to post a writeup but haven't gotten around to it. You're not the first to ask about it.
