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.

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.

What is tegra_mpdecision?
100% kernel based multi core decision! (should cpu1/2/3 be online or not, do we need the low-power/ninja core now?)
This replaces the stock nvidia hotplug solution.
Check /sys/kernel/tegra_mpdecision/conf/ for the configuration.
startdelay = time until mpdecision starts doing it's magic (20000)
delay = time between checks (130)
pause = if something else plugs in the cpu, fall asleep for 10000ms (10 secs)
scroff_single_core = Force low-power mode if screen is 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. (475000)
lpcpu_up_hsyteresis = minimum number of requests that have to be send in order to switch to low-power mode (4)
lpcpu_down_hsyteresis = minimum number of requests that have to be send in order to switch to g-mode (quadcore-mode). Overridden by a requested freq that is higher than the max supported lp-mode frequency. (2)
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
This will regulate when we switch to lp-mode, effectively replacing the quadcore g-mode core with the ninja lp-mode core.
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...
(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/tegra_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/tegra_mpdecision/conf/boost_freqs
for cpu0:
Code:
echo "0 1026000" > /sys/kernel/tegra_mpdecision/conf/boost_freqs
Defaults:
Code:
cat /sys/kernel/tegra_mpdecision/conf/boost_freqs
910000
910000
760000
620000
Recommended governor?
Ondemand.Why do I have no WLAN?
This kernel 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 = userinit (init.d) support.
The zip adds init.d support 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 14060 0 - Live 0x00000000
cifs 239646 0 - Live 0x00000000
bcmdhd 433083 0 - Live 0x00000000
Then init.d support is probably missing.
You can test it by going to /system/etc/init.d/ and executing 00wlan.
Code:
adb shell
su
. /system/etc/init.d/00wlan
Wait a few seconds and try to enable wifi and repeat the above lsmod command (should now show bcmdhd as live, you can execute 01cifs and 02tun too).
If WLAN now works, init.d support is missing.
You need to have busybox installed in order to be able to get init.d support going, this shouldn't be a problem for most people, since it is usually installed when rooting your phone anyway (and who does unlock but not root their phone? :/)
It does not matter if busybox is installed in /system/bin or /system/xbin, my script will detect the location upon flashing and patch the ramdisk accordingly.
If no busybox is found, the script will add init.d support to your ramdisk with the default location: /system/xbin/busybox. All you need to do is install busybox there and reboot your phone.

* Hello World *
What tweaks did you make to on-demand, if you don't mind me asking? The only thing I've noticed is that frequency switching seems to happen faster & more often.
Feel like flashing something tonight!

I mostly adapted it to work with the lpcore while the screen is on and also with special power saving setting while the screen is off.
The 2 phase frequency was changed to accomplish that.
It also applies a powersave bias while screen is off.
Additionally I changed the settings to allow faster scaling with less load. (70% > freq incr)
Source is currently being uploaded, but since I kept the history intact it is taking ages. You can look it up there in more detail once the source is up

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

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.

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.

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.

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.

Looking forward to trying this out! Looks awesome. Just out of curiosity is there any reason why this zip is so much larger than the zips for other kernels?

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.)

I have a Star S9500 with MTK6589 Cortex-A7 Quad Core @ 1.2GHz with PowerVR SGX544 Single Core.
I have the Kernel Source extracted from an Acer smartphone here: https://github.com/varunchitre15/MT6589_kernel_source .
In the MT6589_kernel_source/mediatek/platform/mt6589/kernel/core/mt_cpufreq.c file, in the line 127 has the code:
Code:
static unsigned int g_max_freq_by_ptp = DVFS_F1; /* default 1.2GHz */
If I change it to:
Code:
static unsigned int g_max_freq_by_ptp = DVFS_F0_0; /* OC 1.7GHz */
it changes from 1209000 KHz to 1703000 KHz, as in the line 70:
Code:
#define DVFS_F0_0 (1703000) // KHz
#define DVFS_F0_1 (1599000) // KHz
#define DVFS_F0_2 (1508000) // KHz
#define DVFS_F0_3 (1404000) // KHz
#define DVFS_F0_4 (1300000) // KHz
#define DVFS_F1 (1209000) // KHz
#define DVFS_F2 ( 988000) // KHz
#define DVFS_F3 ( 754000) // KHz
#define DVFS_F4 ( 497250) // KHz
I think I don't need to change de voltage as it is already set to the max supported by the Kernel.
I don't have problems with overheating or extreme battery drain, as I have the CPU Master Pro app and when the screen is off or he is overheating it sets to 500MHz x4.
I want to OC the GPU too, but I can't find the line to change te clock in the MT6589_kernel_source/mediatek/platform/mt6589/kernel/core/mt_gpufreq.c file.
I already built the Kernel in Debian OS succefully, but now I don't know how to put to .img to flash it!
Anyone can build the Kernel and publish it or just tell me what must I do?
EDIT: I just want to be able to play Real Racing 3 at 960p. I only get a great performance at standard FWVGA resolution and if I set 960x1708 @ 390 DPI screen the performance is very good except in Real Racing 3 and other graphical intense games.

Why don't you try to upload and share your compiled kernel (i.e zImage) with us, we can test it, and if it's really working, we can work on overclock gpu too..

I use Virtuous Ten Studio (VTS) you can search XDA for it. Quite popular as it unpacks boot.img, allows edits to ramdisk, and you can swap zimage and pack it back together into a new boot.img
Also, it de-compiles, de-odex, blah blah blah.... Pretty much a 1 stop shop. Runs in windows. Sure beats doing all it from a cmd window!

Ivan, I'm curious. You have a Star S9500 device. And you're using kernel source from an Acer smartphone???
Uhm, unless I am mistaken, you really shouldn't use kernel source from a different device, as the results could be bad. Unless the devices are identical and branded under a different name.
I also am searching kernel source for my ExPlay X-Tremer which uses the MTK6589 CPU.
Am quite interested in your results.

Hi
Well, sorry but you cant OC an Mediatek SoC, it doesnt use those freq-values. Its still an mystery how to do it on that brand. since they will never share the FULL sourcecode.
All you will be able to do, by changing that is to display an "value" it will be only Visual, And not actually overclocked.
So just stop wasting your time on that. Will never work
You can also ask varun his also an kernel developer with experience on the MTK platform. Still the answer will be the same.
On an side note, you just build an kernel that will only work on the original acer device, not yours. It doesn't work that way lol
Its not all JUST about having the same SoC, there are other things:
Alps, magnetic sensor, proximity, etc that you need to config on kernel boardconfig to work on your device.
For packing /unpacking, since this is an MTK device, the best tool is Bruno Martins pack and unpack scripts:

Exactly, not to mention trying to install a kernel meant for another device could have disastrous results...
As far as Full kernel source, I'm not even sure if the device manufacturers even have it. I suppose a lot of these devices are just "re-branded" clones, as I have been getting nowhere in answer on anything from Ex-Play, even citing GPL and such. "Somebody" has it, as 2 other ROMs (MIUI and Lewa) have 2 available ROMs, but I would guess they use the same zimage, considering they run the same OS version.
With the source, could check freq tables, and see if they use a speedo id that can be faked. But without current source, just don't know.

All the available kernel sources for the MTK platform can be found on my git:
https://github.com/dragonpt
And from varunchitre15 git:
https://github.com/varunchitre15?tab=repositories
As for OC, it was already tried in the past, yes after moding the kernel freq it shows OC values, but they are only Visual, MTK code is really weird.
About sourcecode, only some OEM's have release those, and it tooked ALOT of efforts for it (Petitions and so on), and all we got was the kernel source of course, and most of it it's NOT buildable (needs some fixs to compile).
As for my OEM, they said, they never got it, lol funny no?
This is one of the most ANTI-GPL, Closed Source Company i ever saw, in these last years...
Also Mediatek uses alot of Hacks on their code, i.e: the compiled zlmage needs an patch on kernel header to boot.

Thanks Mate. Yeah, looking over the sources, it's quite a mess in there! Tegra3 is so much more in order.
Will have to check my proc, and see which defconfig I use. Seems like a logical place to start. And talk about strange, they use only the Hotpug governor, although it seems several are available, but clearly they aren't set up for the device correctly as only Hotplug works, and the other configs have horrible performance.
Cheers

If you wanna start kernel compiling in this platform, the usuall config.gz wont work, if you are lucky enought you may find some old configs on kernel source code, then the "make oldconfig" should work, if the source doesnt have it then it will be an pain in the a## to compile.
Also some tips:
MTK kernels usually compile only with linaro toolchain 4.6.x or less, higher that this and its gonna be an mess with alot of compiler errors.
About the govs, yes on my tab(6589 soc) seems that the hotplug is the only one working ok, the other 2 govs seems that are only using the first 2 cores.
On the boardconfig, you can add several other govs, and IO,s, but i never add those, i may try that in the future and check if those extra govs work ok.

Thanks for the tip on the toolchain. I usually use Google's latest. Never installed linaro as I really haven't seen a lot of difference in other testing comparisons. Generates a bunch of errors, but usually on things not specific to my device. Sloppy programming I guess.My guess is it's up to the device manufaturers responsibility to clean up the code.

* removes min freq overrides from the ramdisk
* removes governor overrides from the ramdisk
* adds init.d support to your ramdisk (if not already supported)
* modifies stock ondemand settings
* add module insertion
Check the compare links for the rest

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.

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.
Best Nexus 5 kernel il now on N7 ! Awesome ! Thank's for this

Assume this is based on the new 4.4.1?

made for 4.4.1 means only usable on 4.4.1 or works on 4.4 too?
Will this brick my phone
Does Slimport work with this? I have had other kernels flick out after 5 minutes or so.

I can tell you that I am running it on Bruce's 4.4 odexed and is running brilliantly so far. Installed it early this morning and running great so far.

It should.
Give it a try, the install process make a backup of your current Zimage, if something goes wrong, just flash the uninstaller and your'll get back to your unmodified rom.
