Definitely efficiency sky rockets doing this if you dont currently need the power of the A15 cores right now.

View attachment 2237429

As show via this screenshot the power draw at a7 ranges is incredibly efficient :)

Andrei what do you think of the new 5420 clocked now at 1.9ghz in the Note3? Seems this will be a good match for the S800 cpu. You mentioned you likely are not getting a Note 3, so will you look into attaining S5 instead or skip a gen? I know donations help determine what devices you may go to. I'm hoping we would see a GTS setup in GS5 and a newer build of Exynos than 5420.
[Galaxy S 4 General] AndreiLux:
I'll be very interested in the GPU benchmarks coming in. Especially since it appears that the S800 Samsung devices run the 330 at 550MHz. CPU you can deduct from the current 5410, i.e. still the fastest thing out there.

Samsung has a 5440 in the pipeline which should be released later in the year / early 2014 so that might end up in the S5. And you're right on about the donations (Especially on the 9500...); no point in spending on a device I don't want for personal use.
[Galaxy S 4 General] i9100g user:
First Note 3 benchmarks for Snapdragon variant are here

68Fps in Egypt HD and 26Fps in Trex HD

It looks like they are using the 8974AB then.
[Galaxy S 4 General] mw86:
Wow, thanks. I'll look at the info on 5440 :) and watch 5420 as it unfolds. I think I'll jump on the GS5 if we get the 5440 and hopefully enough supportive donations can get you on the platform as well. I switched from qualcomm chipset on GS3 and have not looked back thanks to your kernel for bringing the best of the Exynos out.

[Galaxy S 4 General] im4eversmart:
Very disappointed by this octa core variant, i bought it 3 months ago and now i wish i had bought the snapdragon variant instead. Im not saying implementing octa cores is not a good thing but people expected more from the i9500 version, personally i dont like to be played from samsung and release a phone for people to test, i mean i payed over 700 bucks for this phone so i expected it to be worth it, now im thinking of switching over to the nexus 4 and im sure im not going to get the octa-core version of the note 3 you know what they say , fool me once shame on you, fool me twice shame on me. Hopefully soon, samsung will fix the octa core thing and give people what they want.
[Galaxy S 4 General] matheus_sc:
Octa version have a better gamming performance, better battery life, only problem is cm, but always have this problem in exynos version.
[Galaxy S 4 General] Mushoz:
Heh, I'm slightly disappointed with my i9505 variant. Gaming performance is disappointing with some games. Especially the GTA series are pretty choppy. Unacceptable for current flagship models. I'm hearing that the Octa variant is faster in games.
[Galaxy S 4 General] karlesg:
Do you have any technical info what will be changed in 5440 compared to 5420?
[Galaxy S 4 General] mw86:
Not at all am I saying by this that benchmarks mean everything but the info can be taken with stance that most benches can be +/-10-20% each run on different personal setups. Regardless, the bench if a modernized one done proper does provide a way to judge atleast the raw power of the chipset. That said, i have to say there is no lack of power on this 5410. Efficiency could of been better with proper GTS as Andrei has shown in his posts. This still puts the 5410 top of the market.

Given a throttle I have tuned off of stock here is just a 100mhz boost to stock mhz.

At stock it still is getting 36k like this in Native score for stock 1.6ghz. 37k chainfire native score @1.7ghz. This chip is taking more heat than S600, I can't speak for S800 or others.

The power is great on 5410 just shame the two cpus cant work together :) on this current silicon.
[Galaxy S 4 General] iba21:
5410 could it be the test version for samsung?

I'm meaning about cluster migration..

the 5420 is not commercialized as hoped.. so.. it could have the same cm "issue".. or.. it could have the core migration.. and maybe 5440 will have the hmp.. maybe

I love this architecture but.. it's strange :what:
[Galaxy S 4 General] Szadzik:
I agree. This phones is crap and not worth buying, even though one of the fastest best performing devices on the market.
[Galaxy S 4 General] i9100g user:
New exynos coming?

Good news..

The video looks like the hmp..

8 tabs with 8 different action.. it seems like the 8 cores all turned on, all with 1 tasks, witch works eterogenly eachother

Probably the 5420 in note3 and galaxy tab10.1 will have the hmp logic!!

Probably the 5410 will have it too

GREAT NEWS
[Galaxy S 4 General] AvelonTs:
So the 5410 isn't actually crippled in the silicon as the early claims?

I read on anandtech that the cci-400 bus is actually functional but bugged and disabled ...
[Galaxy S 4 General] AndreiLux:
Deciphering the marketing shenanigans they probably want to describe core migration in that video, probably also the "evolution" hinted by their Twitter. They will NOT release HMP on the 5420 simply due to it being to early in terms of software and kernel.

The 5410 is dead and nothing will change that.
[Galaxy S 4 General] iba21:
But 8 videos is turned on... :(

Are you sure?

Anyway core migration is good too
[Galaxy S 4 General] Degrated Shadow:
The 5410 is dead u say. What does that exactly mean for us i9500 end users? Does that mean 5410 will never have the HMP we thot we would when we bought the phone?

Or samsung experimented on us with this crap load of 2 quadcores?

or does that mean have opengl es 3.0 support less plasticky crap that is not fixable on the software side by even third party developers.. and Did we pay 600 bucks for falsely advertised phone?

only reason I ever thot about getting this phone has a processor that was fastest out there ATM and supposedly it was most battery efficient.. perhaps in first few days I did feel so it was. In a few weeks I come to know I didnt get fully function big.little octa core just a pair of two quadcores? Did samsung just fool us?

or is it still doable?

I do not mean to be rude. I just ask these things because although my experience is good (except for the aosp support) I kind of like to get what I thought I will get when linux kernel patched for hmp arrives and not being experimemted over by this crapsung..

Thats the first reason I bought this.. was I better off with a nexus 4 or a i9505 or a S4 LTE-A??
[Galaxy S 4 General] AvelonTs:
I'm new to this forums but from what i've read so far u have created one of the most renowned kernels around here which leads me to the conclusion that u are actually a very good developer ... so why you decide to develop for a dead SoC instead of the snapdragon one?
[Galaxy S 4 General] Tears for Fears:
Perhaps because that's the one he owns?
[Galaxy S 4 General] mashaal95:
Trust Andrei ;)

You're right buddy...Samsung duped us with this phone! But dont think that this is the end of the road for us, because we have Official CM coming up very soon ;)

Plus, even though its running without HMP, the performance is amazing! The i9505 users also dont get the Wolfson DAC which we all know produces better sound than the Qualcomm DAC :)

Also, we have Andrei who is regularly providing us with new features through his legendary perseus kernel !

This phone will get better, just have patience :)

(P.S 4.3 is coming...so we should be seeing some rather irritating issues being fixed by Sammy :D)
[Galaxy S 4 General] Degrated Shadow:
Although your post assures me.. but my question is will we ever be able to get dirty on that HMP. Because as far as I know if it started working our phone would have even more battery than that freaking droid maxx..

I mean hey I only need one a15 and 3 a7s online.. 3 a7s at highest frequency are supposed to consume less than a single a15 right?

If that logic is ever implemented I agree the switching would become noitceable(hardly though). That would be the only adverse effect against we getting an awesome battery life.
[Galaxy S 4 General] Tears for Fears:
AndreiLux has already said many times that the silicon itself is crippled, so there's no possible way to get it working.
[Galaxy S 4 General] AndreiLux:
It will never have HMP.

To be frank Samsung didn't fool nobody because they never publicly specified anything about how the chip works. But essentially yes the product isn't what it was supposed to be. It's an industrial product failure and I'm pretty sure Samsung felt the financial repercussions of having to outsource most of their device SoCs this generation.

Because when I bought the phone I didn't uncover the story, that and that I'm not interested in Qualcomm for now. And since I'm not made of gold, I kept on going with what I have.

The end result compared to the 9505 is still the same though. It still has better average battery advantage over the S600 while having a disadvantage in high load situations.

Of course I'd recommend an S800 device over any of these right now (The G2 looks amazing) in this moment of time. We've yet to see a 5420 in practice.
[Galaxy S 4 General] Degrated Shadow:
What's the exact problem for not having HMP? Perhaps FSB like thing in the SOC? Or battery can not give that heterogenous output?

Lets say the SOC does not constrain us on enabling HMP.. how would you proceed? By inventing the logic itself or directly porting it from a newer exynos SOC.

And as is SOC will constrain as what would be needed on hardware side to enable it?

Every question I ask is just out of curiosity bro.. I hope I'm not bothering or irritating you
[Galaxy S 4 General] iba21:
Simply, 5410 seems to be the test chip.. maybe the video witch i post is directed to the 5420.. maybe..

The good thing is you don't know anything about 5420.. so.. it could have the cluster migration, the core migration, even the hmp.. nothing is sure till look at a note3 kernel source code

anyway 5410 seems quite good.. it has the "bad" migration logic but, in a normal use, most of the time is spent on A7 cores, witch it has a better power efficiency than qualcomm (in theory)

of the 5420 will have the core migration, it could be even a good thing.. and sure.. with hmp it will be the best over the best

Btw, as i think, in my opinion, exy will be even better for multitasking, cos all cores are still avaible for linux, that's what not happens with qualcomm version, witch has the old hotplug logic..

Power gating is a good way to change to exy..

Sure, you are a dev, you see the chip doesen't do what it should do..

so, for you the exy is incomplete -> failure..

And it's normal..

In my opinion.. i got a lot of qualcomm cores.. and the bad thing is always the same.. /system/bit/MPDECISION

The hitplugghing logic is chosed by a SCRIPT writed in c++

It's not a governor hotplug.. it's a script.. and it's not so good as what should do..

My esperience, with that script hotplug is dinamiccaly and, too slow.. it means core0 will go to maxfreq everytime, other cores will hotplugged at maxfreq, it means max power consuption everytime.. maybe for nothing

That was the stupid qualcomm's logic

One big coder, showp-1984 renamed mpdecision as Make Poor decision..

Qualcomm's asyncronius advantages are deleted by the mpdecision strange logic..

so.. qualcomm has his daemons too

and, i really hate hotplug, it creates lags for nothing.. time spent to the scheduler to give to the new kernel the tasks.. it's better if the schedule always have 4/8 cores always "on".. as my opinion

---------- Post added at 08:36 PM ---------- Previous post was at 07:46 PM ----------

Simply.. do nothing.. it's impossible to get a core migration or hmp witout the source and experience of samsung/linaro coder.. why?

Samsung knows how works theyr chips.. and sure.. only samsung can create the correct "drivers" of the kernel

hmp is a scheduling code.. it means someone has to rewrite the linux scheduler with more code witch can find the 2 different architecture, and, move the correct tasks in the correct core.. and sure.. it may have a double DVFS system witch has to work parallely, since 2 arch has 2 dvfs "table", and so, those chose 2 different frequency/voltage alimentation

As i sad.. 5410 is a test chip.. that's why it's sold only in some place..

The 5420 maybe will fix the cache coercy, maybe will have the hmp, maybe not, maybe it will have the core migration

Anyway, for me the big little logic is better than old hotplugghing

Linus (the coder of linux) chose it too since from kernel 3.6 there is the own compatibility with big.little

And linus is not stupid.. it means big.little has good feature
[Galaxy S 4 General] AndreiLux:
A test chip is a chip which is not meant to enter mass production. The 5410 is a proper chip which has a bug.

Why do you know what I don't know? The 5420 will ship with IKS on core migration, fact.

Bullcrap. The only thing needed from Samsung is a working MCPM backend which we already have on the 5420. Getting HMP working is a matter of upstreaming the kernel core to 3.11 and that's it. I'm talking about the 5420 here as that's just a matter of software, not 5410 where it's physically not possible.
[Galaxy S 4 General] iba21:
well, i apologize about my last post, i REALLY think no-one has news about 5420, since there aren't infos about it.. i tryed to search those anywhere.. always the same 2 things..

if you know more about 5420, very well, i love this arch.. i'm glad to see the 5420 will have the core migration over the cluster one.. it's a really good thing since i'd want to buy the note3..

And i'm glad to see the upgrading on hmp is quite "simple".. it means, probably, maybe, in near future 5420 will have hmp too.. maybe..

Only one question.. MCPM is stil working in the 5420 kernel? Because, if it's trye, as i can understand, the only thing between core migration and hmp is the upgrading on 3.11 source.. right?

Btw as you can see i'm not a kernel dev.. my other were only suppositions, since i'm a radio speaker, not a linaro coder ;)

It's a good thing, for me, if you confirm the 5420 will have the core migration.. it's good for my use (i have a pure multitasking use, no gaminig, only a lot of apps, lot of web pages, simultaneus, every pages opens one tasks, a better multithreading arch will increase the multitasking experience.. so.. for me it's better.. for a gamer user.. all knows that games need high freqs.. not all game's tasks are parallelizzable, so, a faster core is better, intel turbo mode docet.. for those people, sure, qualcomm should be better.. )

Anyway many thanks for your answers.. i'd want to have your kernel in my future note3 exy, but, i don't think it will be possible

You are the first witch added the body bias settage, only one electronic knowledge knows what is (as i know since i studyd electronics), and, i'm using your kernel on note2, it's already the best ever tryed ;)
[Galaxy S 4 General] thekoRngear:
According to this discussion context, I want to know this: Samsung was forced to out 5410 with CCI disabled. They did not demo it in their S4 presentation. Now the 5420 which has a fully working CCI and supposedly an effectively improved version of 5410 my question why samsung again this time chosen not to demo it in their note 3 presentation and why we are hearing that 5420 octa is having production and overheating difficulties?
[Galaxy S 4 General] AndreiLux:
Not sure at this point. Maybe they're re-spinning and tweaking the process node to be competitive to the S800 (TSMC has a process advantage at this point with HPm). It didn't enter mass-production yet.

In either case I don't think they'll be competitive against Qualcomm until next year on 22nm.
[Galaxy S 4 General] Degrated Shadow:
Are you crazy? All I asked was how he would proceed and what would we need even if on hardware side..thats all. Who do you think you want to teach scheduling to? I knw just as much about it I need to know. But you will need the logic understood before knowing. Knowing a thousand people with thousand minds the logic can be different.. once he gets the logic scheduking is matter of time while someone atleast tries to get the 3.6 kernel up.

And simply doing nothing is not an option. If I am gonna improve my phone which I'm gonna use for 3 years then I'm gonna improve it in any aspect I can. You dont want something done please stay out of this.
[Galaxy S 4 General] iba21:
Maybe those are only rumors

The only thing you can know is, 5410 has issues, but it seems doesn't have heating problems.. qualcomm 600 (s4 and one) has HIGH heating issue due to it's own fucchin governor logic..

Don't know the qualcomm 800 and exy 5420 til someone can try it

P.s. i hate overheat.. i hate to grab an hot phone
[Galaxy S 4 General] AvelonTs:
It doesn't have heating problems? hardly ... it does have just as the qualcomm variant and in early firmwares it was considerably worse ... also i didn't do many test about it but in my experience with the one it runs cooler than any gs4

[Galaxy S 4 General] samep:
A little OT on the Samsung phones getting hot in the pocket with battery drain... check to see if your phone is staying awake. If so, do a xda search for sudo sdcardstuck; you'll find a bash flashable mod by SenseiSimple. Running the command in Terminal Emulator will scan your sdcard for media files and identify any hanging during media scan which will cause heat and battery drain. A picture I took with my phone started causing this and had me swapping batteries every few hours until I scanned and found the caper.

Back on topic; looking to upgrade this year: the Snapdragon 800 may be a suitable alternative. The OP suggested the LG G2; looks to be a good and solid design but I'm also looking at the Note 3.

Sorry, if that's OT; there's been some good info by the OP and others exchanged here. The Note 3 release may have revived some interest in the Octa 5420.

The iPhone 5 is another phone that gets hot; my wife doesn't like using it without the plastic protective case.

[Galaxy S 4 General] arvin2212:
How did you do it? I tried flashing the zip file and then installing the terminal app from playstore. Tried 'sudo' but it said command not found. What should I do?
[Galaxy S 4 General] samep:
If you flashed it, you should have the included Terminal Emulator. You can type sudo sdcardstuck. If all else fails, use a root browser to move sudo to /system/bin and sdcardstuck to /system/xbin. Set permissions to 0, 2000, 0755. Then try Terminal command.

Prerequisites: bash and busybox which should be included in a custom rooted ROM.

Apologies to OP for OT.

So this essentially means no improvement for 5410 while owners of 5420 can enjoy their lives ? Nice to know. Atleast I am glad to hear that note 3 is getting true big.little implementation. Only if they could fix the cci in 5410.

Lucky me I did not have a clue how this is supposed to work so as long as the phone is fast I will be happy ;)
[Galaxy S 4 General] krabman:
Yeah, I missed it if they said anything other than it would be a big little configuration in this phone. Not sure if this is just his hopes (possibly) getting dashed? Considering the rushed nature of this phone and the fact that its their flagship device until at least the note 3 and beyond if you look at non giant sized devices I'm pretty confident that there will be some updates. I have to admit that I have been thinking of canceling my order. Phones are getting pretty good nowdays and I have no complaint whatsoever about my sgs3 so the improved battery life was one of the main draws of this phone for me. Without that I think the scales are starting to tip back towards waiting for the N5. Mulling this over as I type...

[Galaxy S 4 General] cmd512:
Really considering canceling my 9500 order and just going with the 9505. With more and more devs leaning towards the Snapdragon and what looks to be minimal battery gains on the octa, really makes the 9500 seem like the wrong choice...

He is the one who is very very enthusiast and devoted to optimize the exynos 5410. We are waiting for more of his clarification regarding big.little which is implemented in the S4 which seems running

He is more worried in the development purposes.
