What is msm_thermal?
Kernel based 3-phase thermal control!
This replaces your /system/bin/thermald binary which is renamed by the installer to thermald_bck.
It will throttle your cpu speed to keep it cool and unleash it if the cpu has cooled down enough. (3 phases: low, mid and high)
Check /sys/kernel/msm_thermal/conf/ for the thermal configuration
allowed_max_high = highest threshold (phase 3)
allowed_max_low = remove the throttling if we cooled down to this (clr_thrshold)
allowed_max_freq = max frequency if throttled (limit)
[...]mid[...] = same as above, just for phase 2
[...]low[...] = Lowest threshold (phase 1)
check_interval_ms = how often shall we check? (sampling rate)
Default: 100ms (=0.1sec)
shutdown_temp = if we reach this shut down the device!
Default: 80°C
If you want to see msm_thermal doing it's job:
Code:
adb shell
cat /proc/kmsg | grep 'thermal'
What is msm_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not?)
This replaces your /system/bin/mpdecision binary which is renamed by the installer to mpdecision_bck.
Check /sys/kernel/msm_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (20000)
delay = time between checks (70)
pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
scroff_single_core = if the screen is off, don't plug in cpu1/2/3. Additionally: Unplug all cpus except cpu0 when screen is turned off (1)
enabled = enable(1) or disable(0) mpdecision. This does not affect scroff_single_core!
min_cpus = min cpus to be online, cannot be < 1. Default: 1
max_cpus = max cpus to be online, cannot be > 4. (if you set it to 2 and min_cpus to 1 you will basically have a dualcore) Default: 4
idle_freq = a value against that will be checked if a core +/- is requested. (486000)
If cpu0 is below that value and a core up of another cpu is requested, nothing will happen.
If any other cpu is above that value and a core down of that cpu is requested, nothing will happen. (otherwise it would now put down that cpu even though it is still working, which isn't what we want)
Hot plug thresholds (aka now it gets 'complicated')
This small formula calculates which value will be used: (number_of_cpus_online - 1) * 2
The result of this formula will be the nwns_threshold where a new cpu is hotplugged.
The result of this formula + 1 will be the nwns_threshold where a cpu is unplugged.
nwns_threshold_x = runqueue threshold, if this is reached cpuX will be hot/unplugged
twts_threshold_x = time threshold, this amount of time must have passed for the related action to be taken (hot/unplug)
Example:
One cpu is online.
(1 - 1) * 2 = 0 ergo:
nwns_threshold_0 = cpu1 will be hotplugged at this value
((1 - 1) * 2) + 1 = 1
nwns_threshold_1 = cpu0 will be unplugged at this value
Since we can't unplug cpu0 this is '0'.
Two cpus are online.
(2 - 1) * 2 = 2 ergo:
nwns_threshold_2 = cpu2 will be hotplugged at this value
((2 - 1) * 2) + 1 = 3
nwns_threshold_3 = cpu1 will be unplugged at this value
etc...
The default values are:
NwNs_Threshold: 12, 0, 25, 20, 32, 28, 0, 35
TwTs_Threshold: 140, 0, 140, 190, 140, 190, 0, 190
Where the position and function of the number equals the result of the above explained formula.
(all times are in ms)
If you want to see the mpdecision magic happening:
Code:
adb shell
cat /proc/kmsg | grep 'MPDEC'
mpdecision's input event boost, aka project butter
This will boost your min cpu speed if you touch the screen or press a button and gives you full control.
In those events the min cpu freq will be risen to a predefined value (look below) on every online cpu. This boosts overall reaction times and smoothness a lot. (works similar to the qcom mpdecision binary)
Configuration files:
[email protected]:/sys/kernel/msm_mpdecision/conf # ls
boost_enabled
boost_freqs
boost_time
All of them work like the usual sysfs files, except one special case:
boost_freqs will list all frequencies from cpu 0 to cpu x. Cpu 3 and any following cpu will share one frequency.
To change those frequencies echo the cpu number + the frequency in khz. To change the boost freq of cpu3 (and 4,5,6,7,8, etc) the echo would look as follows:
Code:
echo "3 1026000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
for cpu0:
Code:
echo "0 1026000" > /sys/kernel/msm_mpdecision/conf/boost_freqs
Defaults:
Code:
cat /sys/kernel/msm_mpdecision/conf/boost_freqs
918000
918000
702000
594000
How does sweep2wake work? Does it keep my phone awake?
Short answer: No.
Long answer:
Sweep2wake works with IRQs (Interrupts).
An interrupt can be best imagined as you doing something, like shopping at the local super market, when someone jumps in front of you and punches you into your family jewels. You will most certainly not just continue shopping.
In technical terms: An Interrupt interrupts the normal operation of a program and executes "special" code instead.
So if you touch your screen, an interrupt is send on which the touch driver reacts. That's it.
Since we have a capacitive touchscreen you also do not need to worry about any pressure onto the screen.
If you want to disable sweep2wake execute this command on your phone (adb shell or directly), you can also add it to an init.d script.
Code:
echo "0" > /sys/android_touch/sweep2wake
(echoing "1" activates it, which is the default setting)​Recommended governor?
Ondemand.​Why do I have no WLAN?
Due to this kernels very high optimization settings it is too big for our boot.img with WLAN included into the kernel, so it is built as a module. That means it needs to be inserted into the kernel upon boot up, which needs to be automated for maximum comfort.
The zip adds this to your ramdisk, if that fails for some reason the wlan module cannot be inserted.
if
Code:
adb shell lsmod
doesn't show this:
Code:
tun 14701 0 - Live 0x00000000
cifs 275399 0 - Live 0x00000000
wlan 2964650 0 - Live 0x00000000 (C)
Then something went wrong. (My fault)
You can test it by executing
Code:
adb shell
su
insmod /system/lib/modules/wlan.ko
Wait a few seconds and try to enable wifi and repeat the above lsmod command (should now show wlan).
If WLAN now works, I messed up.
Open a new issue in the issue tracker and it will be fixed asap.​Last release for 4.2.2?

From a thermal point of view: Yes.
But if you set a too high clock and your chip craps out because of too much voltage, that won't save it.
Overclocking is dangerous. It will never be safe, the thermal guard just makes it as safe as on any other phone.

Yes, because of sooooo many optimizations I pumped into the kernel it was getting pretty big, too big for it to fit inside the boot.img with the ramdisk. SO I had to remove stuff from the kernel and put it into modules (wlan,cifs,tun) which are inserted into the kernel upon boot.
You won't feel the difference but it enabled me to include these optimizations.
(the prima wlan module is 22megs or so... freaky big thing.)

[Q] Where is the source code for android cpu governors?

I want custom governors like ondemadx, smartass etc. But unfortunaely i can not find the source code. please guide.
You don't find the code for the governors where they usually are? ...at "linux/drivers/cpufreq/" that is? (Part of the kernel source code.)
They have a name pattern matching: cpufreq_*.c. For instance "cpufreq_powersave.c" or "cpufreq_smartass2.c".
Perhaps one need device specific kernel source code in order to get the governor sources, but I'd find that strange.
I am experimenting with custom governors on my nexus 4. So have cloned msm kernel from android source. This clone does not have ondemandx or interactivex or any of the custom governors in /kernel/drivers/cpufreq except the default ones like ondemand. Searched for some reliable sources for ondemandx.c and interactivex.c. put these files in /kernel/drivers/cpufreq/ and tried to build source as instructed
1)msm_kernel/drivers/cpufreq/Kconfig
config CPU_FREQ_GOV_ONDEMANDX
tristate "'ondemandx' cpufreq governor"
depends on CPU_FREQ
help
'ondemandx' - a "ondemandx" optimized governor!
2)msm_kernel/drivers/cpufreq/Kconfig
config CPU_FREQ_DEFAULT_GOV_ONDEMANDX
bool "ondemandx"
select CPU_FREQ_GOV_ONDEMANDX
help
Use the CPUFreq governor 'ondemandx' as default.
3) msm_kernel/drivers/cpufreq/Makefile
obj-$(CONFIG_CPU_FREQ_GOV_ONDEMANDX) += cpufreq_ondemandx.o
4) msm_kernel/includes/linux/cpufreq.h
#elif defined(CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMANDX)
extern struct cpufreq_governor cpufreq_gov_ondemandx;
#define CPUFREQ_DEFAULT_GOVERNOR (&cpufreq_gov_ondemandx)
. But unfortunately the .o files are not created. When i see in menucnfig-> cpu power management/ frequency scaling/ the ondemandx and interactivex are listed but like [ ] not like [ *]. i dont understand what wrong i have done.

Whoever disables fsync is a maniac. It is not in this kernel and will never get in. That's my totally honest opinion.
Using a no fsync, or 'dynamic' fsync kernel is the equivalent of jumping from a skyscraper with nothing but a napkin.

I figured it wasn't supposed to work so I didn't report it so I flashed slimkat

Need help of kernel experts.

Hi,
I'm using YU Yureka Plus YU5510A with 64-bit octa-core Snapdragon 615 processor running CM13 snapshot.
Coming to the point, I want to change the default cpu governor and I/O scheduler and default min frequencies.
I tried adding init.d script for governor and I/O scheduler:
Code:
[B]#!/system/bin/sh
echo 'ondemand' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
echo 'ondemand' > /sys/devices/system/cpu/cpu4/cpufreq/scaling_governor
echo "noop" > /sys/block/mmcblk0rmpb/queue/scheduler
echo "noop" > /sys/block/mmcblk0/queue/scheduler[/B]
And I tried editing build.prop
Code:
[B]ro.min_freq_0=200000
ro.min_freq_4=200000[/B]
But these Scripts doesn't works at all
everything reverts back to
Governor = interactive
I/O scheduler = cfq
min cpu0-3 freq = 960000
min cpu4-7 freq = 800000
P.S: The device just ignores the minimum frequencies edited in build.prop while using "interactive" governor and "cfq" I/O scheduler and keep running the device at
min cpu0-3 freq = 960000
min cpu4-7 freq = 800000
and even manually No-frills CPU Control the device ignores the min frequencies and continues to use the default frequencies mentioned above.

I want to report to the administrator. that you swore in this status! Be the decent person!
I flashed this kernel.
Few things to note :
1) Big Cluster only clocks to 2184Mhz, unlike the 2.3Ghz that has been posted.
2)GPU OC goes till 1.1Ghz, not the 1.3Ghz that has been posted.
3)No voltage and Power level control for the GPU, as posted by the OP.
4)Schedutil has been removed and replaced with the default hmp governors: interactive, performance , powersave ......
5) No voltage control for CPU.

If you can't handle a swear word (in any language) I might suggest getting off xda?

Thanks for repot
I have used this kernel for the past week and a half.
I use my tab for media consumption like Youtube, Netflix.
I don't play any games on my tab.
I've been using the Legion OS GSI along with this kernel, and it has been the best I have ever experienced on this device.
Battery backup is great.
The screen on time is great. I get anywhere from 8 to 10.5 hrs, during media consumption.
Responsiveness is good, though I do have the little cluster set to performance and the big cluster on interactive.
Overall, this kernel + LegionOS GSI = amazing combo for this tab.
I would love it if the other features mentioned in my earlier post (which are in the OP but not in the kernel ) were finally added, but even as it is , this kernel is pretty good.

Nice
i tried to flash on a stock rom (rooted unlocked) but it doesn't works. bootloop for me.
does anyone try it yet?
i'm using an sm-t510
Hey guys just a quick question:
Is it good for gaming? Does this focus on battery life or performance more?
Pls reply I've been searching for a week now.
this still under development? or abandoned?
Link for download is not work
can someone repost the kernel? link is broke.
