well.. i was the member witch opened the threads about hmp test over exynos 5420..

and, i suppoused samsung chosed to release hmp for our note3, but, i'm thinking it won't do it for our phone.. why?

i find the core migration code, probably it has some glitches, probably not, why samsung doesen't add it to our note3????

because off it uses the CCI interconnection? because it shouldn't work good? I'm suppousing samsung won't release hmp to preserve that feature for gs5 or note4

as videos, you can see the hmp working over the 5420, not over the note3, so, hmp is real working, it works over 5420, and, why samsung is not releasing it?

http://www.samsung.com/global/busin...eterogeneous_Multi_Processing_Capability.html

read the last line of the first post.. avaible to customers in Q4 2013.. well.. i'm not an english motherlenguages, but, customers for me is who BUY the product.. i bought the 5420 in the note3, so, i'm one of those customers

we are at an half of december, so, last 15 days of those Q4 of 2013..

WHERE IS THE HMP????

and now i see samsung had the CORE MIGRATION coded in gune..

i thought samsung doesen't want to compile the core migration to spend all budget to release hmp as soon as possible.. but.. now i find a core migration code..

thus.. we have the best mobile chip ever in that WORST settage

thanks samsung.. thanks for all

Guys, I whats the problem, I flashed v3.0.1 Normal IKS-Core.

All good, performance is AWESOME except RANDOM REBOOT....

Especially on full load....

All settings default.... I only test with Antutu for stability and Order&Chaos Online game....

Could anyone please help me? And what I must provide to get help? last_kmesg log?

---------- Post added at 09:05 PM ---------- Previous post was at 09:00 PM ----------

The CCI interconnect is fully working in 5420 (Note3)....

It WAS broken in 5410 (S4)..

So I assume that Samsung's being ****ty for not providing real driver to activate that...

Its like HMP hardware is there, but we will not activate it, buy S5/Note4 instead.... More to prove of concept than reality...
[Galaxy Note 3 Exynos Android Development] iba21:
cci needs kernel code to be share datas on each caches of the 2 clusters
[Galaxy Note 3 Exynos Android Development] Crescendo Xenomorph:
That's why I said that the hardware is there but no driver/kernel code to activate it....

Shame on Samsung....

[Galaxy Note 3 Exynos Android Development] iba21:
Well i'm tring right now :D

do you see system kernel works as core migration? do you see the "mix" of A7 and A15 cores too??

---------- Post added at 06:36 PM ---------- Previous post was at 06:19 PM ----------

MAYBE CORE MIGRATIONS IS WORKING!!! :eek::eek::eek::eek::eek::eek::eek:

YOU ARE A GREAT!!

i'm loking to the cpu sage.. and.. sometimes X cores is/are to 650mhz (maxfreq of cortexA7) and other to higher freqs (cortexA15)

it means there are X cores with is/are at cortexA7 and the other to cortexA15

man I LOVE YOU

finally we could have core migration to our SoC.. i really hope i'll not have that cortexA7 issue as i had with other versions of your kernel

well.. i'm testing and i'll share my experience

p.s. i know how exy 5420 works, but, really i didn't realize that you talket about core migration.. i have doubt about samsung, so, i think they won't release core migration or HMP for owr note3 only for commercial use.. that why i didn't understand, and, posted those links..

well.. you are a great

---------- Post added at 06:39 PM ---------- Previous post was at 06:36 PM ----------

i see the b.L_core_stat are glitchy

i'm meaning the sysfs in folder

/sys/devices/system/b.L

well core migration seems is working good.. really good, even if i see there is only the A15 turned on + the 2 caches

[Galaxy Note 3 Exynos Android Development] kadiremrah:
thanks and ...

iba21 first thank you for your fast response.

I want to ask you one more thing. I was using goodhanry kernel and try to install PowerS v.3 pekaka kernel. System UI is crashing over and over. How do you switch between kernels any cleaning script or it is ROM fault.

Thanks,
[Galaxy Note 3 Exynos Android Development] pekaka:
may note3 use cluster,note4:)use core,so leave these bugs,haha
[Galaxy Note 3 Exynos Android Development] iba21:
It's normal.. you have to WIPE system dalvik and cache(no data).. reinstall original rom + patches.. and after that you could install the new kernel

Why? Modules ;)

---------- Post added at 08:29 PM ---------- Previous post was at 08:13 PM ----------

As i suppoused.. min temperature of the cpu is incresed due to second cache operating.. now with core migration all 2 caches are on and are direct connected with the CCI

Traduct.. cortexA7 has a 512kb of L2 and cortexA15 has 2Mb of L2.. now.. all 2 are still on, and works in the same time.. so.. it has a LITTLE more consuption by low tasks..

BUT.. middle and high tasks now could use the benefit of cortexA7 if the single core cluster hasn't the necessity of more power.. traduct.. less consuption and less heat by using the phone!

I cant beleve i have core migration

Many tanks.. please share a link.. i'd want to pay you a beer!!
[Galaxy Note 3 Exynos Android Development] pekaka:
another,the whole initramfs is different(I use stock kernel),so must be running new kernel from the beginning of the ROM
[Galaxy Note 3 Exynos Android Development] iba21:
Yes right.. the better way it to reinstall the original rom (with it's own kernel) and install your over it
[Galaxy Note 3 Exynos Android Development] zeyadhan:
great work pekaka
[Galaxy Note 3 Exynos Android Development] kadiremrah:
Rom

I think it is caused by ROM. I installed VN Rom after Sytem,Data,Cache,DalvikCahe format and install the kernel same faults agaim. Sytem UI crash faster than pressing OK. :)
[Galaxy Note 3 Exynos Android Development] P30SiNa:
I have a question.

Core Migration == HMP?

Or they are different?

and with this core migration thing can we expect heat up while doing heavy works?

Thanks.
[Galaxy Note 3 Exynos Android Development] iba21:
Hmp= 8 core indipendently each others..

Core migration = 4 core mixed at a pair of (1 A7 and 1 A15)

Cluster migration = 4 cores, OR 4 A7 or 4A15

Now we have core migration, so, we can mix A7 and A15.. ex.. now we could have 2A15 and 2 A7

Hmp is different.. all cores are indipendent.. so.. it's possible to have only 1 core on.. 0 (zero) too.. to 8..

Hmp is better than core migration.. but it needs a more difficult code.. i'm meaning.. developers has to rewrite all linux scheduler to implement the hmp

Core migration is a newer better code over cluster migration

So.. cluster is the easyer code.. only 2 cluster

core is better than cluster.. 4 core mixed

Hmp is the best, but it needs a very huge kernel modify!

Well.. core is good to because, in normal usage, 4 a15 cores at 1.9ghz are too mouch..

For ex.. i'm writing this on the phone.. as i can see.. with cluster migration i always had an 1.6ghz of cpu sage of each 4 cores.. now i have 1 core at 1.6 and other 3 at 650mhz

You have to know 650mhz is the maxfreq of cortexA7.. so.. now i'm using 3 cortexA7 and 1 A15 over the 4 A15 of the past!

It's better!
[Galaxy Note 3 Exynos Android Development] P30SiNa:
Nice explanation man! Understood perfectly.

Thanks :good:

Maybe we can expect an official core migration update later for our Note 3 from Samsung. Hope so!

But anyway... developers are doing it and that's good
[Galaxy Note 3 Exynos Android Development] iba21:
The real goal should be to have hmp.. why?

For ex.. now you have 4 cores on..

With hmp kernel can turn on 1A7 and 1A15.. so.. 2 cores.. indipendent.. from 0 to 8.. absolutely mixed.. and sure.. kernel could run a task into A7 core, if performance is too low, move to A15..

That's the best over the best..

I don't think samsung will release hmp soon..

Where were samsung when it could compile the core migration???
[Galaxy Note 3 Exynos Android Development] pekaka:
I had managed to build special kernel , no freqs,I get rid of all freqs and running ok!,check only 0 MHZ,but can running,instesting and don't know why is working?
[Galaxy Note 3 Exynos Android Development] iba21:
I don't understand what you sad but.. if you are meaning the 0mhz.. it's because big.little uses power gating tech..

In more words.. chip areas auto shuts down if kernel doesen't need it..

So.. if kernel chose to switch one core to 0mhz.. this core auto shuts down

Sure.. it's a scheduling logic.. so.. scheduler may have the possibility to put 0mhz on a core

That's why hmp could shut down all cores.. simply.. scheduler doesen't assign tasks computation to cores..

I don't think it's possible to use it with core migration..

At last we could have 4A7 on at minfreq.. not less than those..

The old way uses hotplugghing logic.. the kernel hotplug send to cpu driver to shut down the core..

Now it's completely automatical as like a C state in x86 cpu

So.. no tasks computation in a core = core turned off

[Galaxy Note 3 Exynos Android Development] kadiremrah:
Maybe implementing sched_mc with aggressive mod (2) can help power consumption.

Like iba21 said cpu temp is always high (near 50 celcius)

But a perfect show off to samsung.. :)

Go on your good work pekaka.

.
[Galaxy Note 3 Exynos Android Development] iba21:
well the BASE temperature is little more.. about 1-2 degreese..

when you get 50 celsius.. with cluster you should get about 65 or more ;)

4cortexA15 at 1.9ghz reaches about 75-80 celsius..

so.. 50 is absolutely normal in normal/heavy usage

not when you write a text on whatsapp

anyway it seems it has a good battery usage.. about 10% for 1h of screen on in writing + some facebook

it's better than my old note2 :laugh:

many thanks pekaka!

Over night response is same as stock kernel. Only 17mA usage which means %0,6 per hour.
[Galaxy Note 3 Exynos Android Development] iba21:
It's good

What do you think about the power consuption in normal usage?

It's strange.. i got about the same ammount of hours than the cluster migration, but the temperature of the cpu is lower :what:

I never go over 40celsius in normal usage
[Galaxy Note 3 Exynos Android Development] karthickkatta:
Nice kernel what about the random reboots
[Galaxy Note 3 Exynos Android Development] iba21:
No one random reboot..

I'm using the normal version to see if it has a lower battery draining.. maybe powersave could have issues

Just test! :D

Anyway i repeat no one reboot.. never.. and no issues at all.. i'm meaning my femouse issue witch turns off the cluster migration to cortexA15

After about 20hours (no reboot) never ever had one reboot/one "mechanical" issue
[Galaxy Note 3 Exynos Android Development] kadiremrah:
perfect.

No problem. No reboot. Perfect performance.

Normal version iks core has 5 celcius cooler cpu over usage.

And normal version can go over 85 celcius on load. I think termal id has changed.

As seen on screenshot over 85 celcius max freq. Locked [MENTION=4149147]1.8[/MENTION]Ghz when on previous kernel cpu temp does not go over 75 celcius. This version is good for squizing more performance from cpu before thermal id slowdown cpu.
[Galaxy Note 3 Exynos Android Development] iba21:
Did you try the powersave version?
[Galaxy Note 3 Exynos Android Development] aegeuss:
Guys, I had a random reboot too, in normal version; it seems we need a tough beta testing process for stability; may be too much default undervolting, I don't know. I am back to Henry's kernel, which I am fine with 75 mv UV, I did not have any problem with it.

[Galaxy Note 3 Exynos Android Development] kadiremrah:
PowerS

Used PowerS version over night. And come to Normal this morning.

Normal Version 5~10 celcius cooler.

PowerS Version getting ~500 point more on Antutu

Get no problem with PowerS version.

I see that on normal usage iks core use 70mA more current than stock kernel.

Could you change the minsampling rate of conservative governor from 100.000 to 50.000?

It should be easy foy you.. opem the conservative.c value and change the value in the varius place of the file.. if you give me the conservative.c file i'll do it for you

I'd want to use conservative with a faster ramp down.. as i can see.. interactive is good due to it's 20ms of refres over 1.7ghz

So.. faster ramp down

But.. while high navigation, as like more web pages at the same time, cpu goes to 1.9ghz and increeses too mouch the cpu temperature

[Galaxy Note 3 Exynos Android Development] iba21:
There aren't any touch boost in interactive.. simply, if cpu usage go over an ammount of %, it goes to maxfreq.. simply :D

It's to prevent a saturation of the core.. so.. max performance

You may change to ondemand if you would have a slower ramp up

Yes it should be fine. However, there's always risk with what apps you installed and with how you configure your device as far as the stability is concerned.

[Galaxy Note 3 Exynos Android Development] iba21:
I'm using the powers and i never ever had reboots..

With normal version.. 1

Heatness.. my cpu is cooler than cluster migration.. so, in theory less power consuption.. but i still do about 1% 3minutes of screen on.. too les for a note!

P.s. with cluster migration the cpu energy consuption was similar..

For the rest.. core migration works perfect

I advise to all of you to wipe all, reinstall the rom, and after that reinstall the normal version

@pekaka.. are you quite sure core migration is really working?

i'm meaning, when core goes to 650mhz, does it the cortexA7 really? Because i'm starting to think that it's in real the cortexA15.. why?

I have a very strange consuption, and, as i can see, the most freq used in my day is 250mhz, the second is 650mhz, don't understand why it has that high consuption in normal load

if i open the b.L stats, in b.L_core_stat i see always 1111 over cortexA15.. i suppoused it was a bug, but, and if it's real?

in b.L_info all values are at 0

if it's real, that's a probably way to understand why of that hight consuption with stupid tasks..

do you have any idea?

anyway when i come back (this evening) i do a benchmark test to see if it's real.. installed the cluster migration and run the benchmark at 650mhz fixed.. if benchmark is symilar as the core migration, cortexA7 is really working

LITTLE TEST.. i did a stress test with maxfreq of 650mhz and cluster migration.. and i couldn't go over 45 celsius.. now i test the same.. cpu goes over 55 celsius!!

as i sad, for me the 650mhz is in real the CORTEXA15

that's why of an hight battery drain in low tasks.. and that why phone is ALWAYS so fluid.. ALWAYS.. that's what i saw right after the installation!
[Galaxy Note 3 Exynos Android Development] kadiremrah:
power consuption

I want to say core.migration has high consuption but i dont have a clue because MK2 Roms reported has high consuption. So i have full wipe and flash criskelo mk1 and night datas are good. Down to 11 ma from 15ma over night. But it is too early to say something. Because after full wipe i have to wait battery to calibrate (i also delete battery stats).

650mHz found is strange and can be true.
