Nope, didn't touch any voltages at all, just changed those two :)
[Galaxy S 4 i9500 Original Android Development] Chuck Bartowski:
I have 1,9 GHz stable.

Voltages:

From 800 MHz to 1600 MHz all frequencies: -75 mv.

1800 Mhz: -25 mv.

1900 Mhz: untouched
[Galaxy S 4 i9500 Original Android Development] Xphoid:
curious about your default voltage values,,,, and while being stable ie did you try to cf bench? and still no reboots or SOD?

Yes I did, and that guy is a moron and doesn't know what the hell he's doing. He's shown no evidence of the cores running together, he's claiming idiotic clockspeeds (2.8GHz when it's just 2x1.4GHz??!), and his benchmark scores match exactly the what the A7's alone are getting which simply states that he never ran the 8 cores.

lil' bit off topic but ya all seen this yet? http://www.sammobile.com/2013/07/23...-5-octa-soc-based-on-arm-mali-t628-mp6-cores/

Looks promising... still not a word about CCI or IKS/scheduler and all that bs they pulled with 5410...

also if I remember correctly all the newer mali 6xx are supposedly really power hungry which is why nobody's using them in their SOCs - if so pairing it in 6core config with cortex A15 and brokenass clustersswitching might not be a good idea...

Yes because I had given you the script with 750mhz as the up step level L yours was scaling properly. When this was lower than the max mhz set I think is where it caused the scaling issues.

I had this on a build between 6.1-7.1 but I had done plenty of benching so I don't know where it popped up. When i'd swioe all recents away it would fix it sometimes so it seemed I/o kept the cpu alive. Only once did I have to reboot to return to normal. Lot of times setting max mhz below that and back to normal max solved it too. Current kernel I have not ran into this. I will post back if I do.

[Galaxy S 4 i9500 Original Android Development] Alberto96:

[Galaxy S 4 i9500 Original Android Development] iba21:
And ondemand-sec is similar as pegasusQ??

It was the best governor ever for battery saving.. and now samsung doesen't write it for his new phones???
[Galaxy S 4 i9500 Original Android Development] Xphoid:
I really don't have any clue about pegasus... this is my first sammy... but with AndreiLux's touch, everything is awesome here...
[Galaxy S 4 i9500 Original Android Development] mw86:
Basically because our cpu has powergating, we don't use hotplugging in the traditional sense. Since we don't use hotplugging, we have no use of PegasusQ, a hot plugging governor.
[Galaxy S 4 i9500 Original Android Development] iba21:
PegasusQ is not only an hotpluggher governor, but, it has a conservative logic mixed with an ondemand..

I don't understand what you mean as powergating and with the traditional sence.. the real thing is.. qualcomm use mpdecision, nvidia uses cpu quiet, samsung uses pegasusQ..

If you have some more infos about it.. how to chose the hotplug of the core in this new big.little?
[Galaxy S 4 i9500 Original Android Development] mw86:
I had a qualcomm chip and i know of mpdecision. This chip when there is no load on a single core of 4 in a quad core cluster will take no power as it power gates the core instead of qualcomm hotplugging it has to do with the highK metal gate. No need for hotplugging cores with a governor or sevice as the android os controls it in the sense that no load on the core it's powergated.

You can disable cores but it's pointless according to Andrei and I agree. http://xdaforums.com/showthread.php?p=41595848 there is even an apk in there to disable them instead of command but again no need to have less cores available. We don't need to try to hotplug ourselves it does fine job stock.
[Galaxy S 4 i9500 Original Android Development] iba21:
Wait.. WHO chose to powergate a core.. the kernel? The firmware? The modem?

You are saying there isn't an hotplug logic.. but.. the phone do it with the powergating.. ok.. so.. linux (kernel) has 4 cores (double), it has some tasks to compile, he use all of 4 cores (if parallelizzable or if tasks are in different threads), ok, a normal OS has an huge ammount of tasks, it means, 4 cores are nothing as that ammount, so, all cpu are always turned on.... ??

If you have a datasheet about it.. i could be so thankfully.. because.. that was the governor hotplug logic: look at the ammount of tasks, if core_n is more than an ammount of freq, governor says to logic driver to turn on the next core..

And the same as the opposite.. that's to help the main core with some helps from the newer cores..

Don't know if i'm saying it as simply as possible..

But.. i really want to know how this "new" (??) Function work.. who chose when powergate and why?
[Galaxy S 4 i9500 Original Android Development] mw86:
Some of the terma i used may not have been used fully correctly, I'm no pro :).

If you have not read this thread, I would start here on the Original Post of the thread. Andrei put together an incredible read on the entire function of the chip and even debunks myths on it's function.

http://xdaforums.com/showthread.php?p=39172453

All i was saying is for this cpu Pegasusq isn't needed and somehow the power gate is a form of hotplug bit we don't need to control hotplug, any core on the big or little quad core cpu which is active which does not recieve a thread to work on gets hotplugged/powergated meaning no load on that core there is no power being used. This cpu doesn't need as much in the line of hotplugging as per say a qualcomm cpu. So i don't know exactly the logic involved in the power gating but it's as simple to my knowledge as no load on a core in am active cpu cluster then no power drawn on that core.

I since the last 2 updates I get a wakelock with wlan-rx-wake and have had to go to wanam's kernel. Is anyone else experiencing this?
[Galaxy S 4 i9500 Original Android Development] iba21:
No ok.. you thinked i was talking about the switching between two architectures! Eheh

PegasusQ has a coded logic witch whose when hotplug or not a core.. it send an hotplug command to the cpu driver, and that do the other

A7-A15 switch is "passive", is controlled by the driver, and sure, the internal hardware of the chip..

System sees this octa core as a normal quadcore since OR you aliment an A7 or an A15..

sure.. the other will be shutted down

I was searcing infos about that because pegasuQ seems to be the best governor for performance and battery saving balance, why?

Simply, cpu quiet and mpdecision has a DINAMICALLY choice.. translate.. always at maxfreq.. but.. why to put core at maxfreq if you can compile the same with 2 cores at less freq??

You have to know more freq more voltage.. more tension MORE AND MORE power usage..

So.. it's better to aliment 4 cores at 500mhz than 1 core at 2ghz.. the teorical compute power is the same, but 1core at 2ghz needa a lot of voltage to be stable..

That's why i chose samsung..

Htc always uses ondemand governors.. i has a lot of htcs.. my last.. oneX.. i got a good feeling at the last mounths.. when i used the SMARTMAX governor (an intellidemand + conservative logic) + showp's mpdecision.. so.. i create a fake pegasusQ..

Translate: from 2h30 to 4h of screen on with the same cpu and the same usage.. why?

If cpu always go to maxfreq even if load is not high, you are losing energy FOR NOTHING..

And battery consuption is all in a mobile phone.. so.. performance logic is not.good for a daily use phone :p

Don't.know but.. a krait 400 or an exy octa with pegasysQ should be the best ever, you can set all as you need, and there are some features (asincronism in qualcomm and companion in exy) with could decrease the consuption in slow tasks.. but.. don't know why samsung didn't compile it in its new phones :what:

It should be possible to rewrite it for the new phones.. but.. it's a long long work for one person..

[Galaxy S 4 i9500 Original Android Development] AndreiLux:
Power-gating is done per CPUIdle instead of a separate mechanism. There is no hot-plugging.
[Galaxy S 4 i9500 Original Android Development] iba21:
Do you have any datasheet or manual to understand it?

I could be difficult to understand but.. what's the difference from powergating and hot unplugghing? It seems the same..

Even, if there isn't a code witch hotplug/unplug the core, who chose when is necessary to use 1 core and when 4 cores?

I understand probably there isn't an hot unplug command to the driver, and the mechanic is "passive".. core auto shuts down if it doesen't have anything to do.. but.. someone (kernel) has to send to it the assembly infos of a tasks.. so someone has to chose when and where send that tasks onto that core.. or not? ;)

It's strange but.. seems really a good idea.. no more script or hotpkugghing logic?
[Galaxy S 4 i9500 Original Android Development] MuertoKo:
It just doesn't switch any core off
[Galaxy S 4 i9500 Original Android Development] iba21:
Yeah.. but i want to know how to.. not only the final effect..
[Galaxy S 4 i9500 Original Android Development] MuertoKo:
If I'm right, and I may not be, you just can't switch them, it's not built to be able to switch off cores. You can simply search for bibliography about this chip and how it works, there's plenty out there, hotpuligging is dead (Andrei actually said something like that in some post some time ago?)

I guess Andrei won't waste his time trying to explain this off-topic until you actually look like having read a lot (at least I would).

Anyway hope you get a better answer than mine but it's the safest (not easiest) way to proceed.
[Galaxy S 4 i9500 Original Android Development] AndreiLux:
I already said it above, CPUIdle is in charge of the policy. Hotplugging is a convoluted and shítty software method to remove a component from the system. The 5410 migrates interrupts to other CPUs and has a special C2 boot mode where it can resume work as it was. Powergating is now a normal idle state.
[Galaxy S 4 i9500 Original Android Development] iba21:
But.. last question.. with the powergating chip disable all the core's area, or, it possible to "shut down" only one area?

Ex.. if in use only the FPU/neon, shut down the alu area... ??

I understand it's a good thing coded in the hardware lf the chip.. chip auto chose when aliment or not the core, so, no more mpdecision or cpu quiet or similar.. :D
[Galaxy S 4 i9500 Original Android Development] mw86:
In simple terms is a core is idle it's not using power. This happens on idle all the time and even 3cores could be powergated of 4 active cores. It's fast efficient and warrants no explanation as it just works and cannot be modified, it's behavior that is.

Mpdecision you should give up the term, it was used on my previous phone, a qualcomm chipset... you will not find that on this phone and a hot plug governor would only mess up thw unique way this chip runs. This chip's features bring it to the present and future in tech and all those old methodology of hot plugging are just that... old and outdated. Andrei gave the clearest answer.

These posts should be in the discussion thread not Andrei's development thread. But as Andrei stated in past, no REAl development being done here by anyone but him... so these off topic posts will make no difference where they are as Andrei then has to follow two threads of nonsense. :/ He really doesn't have time for that working on several kernels constantly and for some phone's he doesn't even own.

Join in the discussion thread if looking to post about the inner workings of this chipset. Save the space for legit kernel development questions and inquiries. Hassam, Xphoid and many others participate in that thread so you will get answers just the same there.
