Re: [Kernel][Mar 24] Perseus

Lol I had my old OG evo clocked at 2GHz. So its quite a surprise that people saying it will "brick" your phone. It was an old phone. Yet couls of handled the speeds. Was supprised when I came over to Samsung to see the big hype over OC to 1.8GHZ. I think it would handle 2.0ghz if an old first 4g phone could of handled 2.0GHZ and the processor was only a 1 GHz Qualcomm QSD8650*. Compare that to our 1.6GHZ quadcore ? Pretty damn positive it will work too. Dnt ask me to try it lmao Im not the one with the big cajones. . Though maybe OC for the note 2 can go 2.5GHz. Since it already has a great processor. But of course. You could mess up hardware if its running at OC every day. Ill just OC when I really need it oh and yea this was 3 Years ago.

You can take an Intel desktop CPU and get it to 6gHz....and you'll smoke it due to voltage and electromigration in a matter of days or weeks even under LN2.

Sure you can clock a Note2 up to 2gHz probably, but no one can tell you how long the proc will last under those conditions before it becomes unstable. Moreover why bother? The device handles decently at 1.6gHz even under (bloated) stock Twiz ROMs. Lighter weight AOSP ROMs handle just as well at far lower clocks...I'm playing with an AOSP ROM right now and I notice no difference in visual performance between stock 1.6gHz and underclocked and undervolted down to 1gHz max.
[Sprint Samsung Galaxy Note II] lovekeiiy:
The Kernel developer stated he wasn't trying to push limits of the CPU, but only wanted to make available speeds that were stable and safe. I'm not doubting the what you say about your phone. I presume 2.0ghz is probably fairly safe; I don't know if chip makers are as conservative with the clockspeeds as they used be. Give given the GN2 Eynos chips is a quadcore at 1.6ghz, it can process four instructions at the same time, unlike other phones that can only do one or two. Even though it may not have as high clock speed, it's still doing more work. Hopefully Android and the apps we use can make use of the four cores.

Then there is all the other stuff the other have said that relate to heat. Overclock it to the 3ghz and keep an ice pack on the phone, LOL.
[Sprint Samsung Galaxy Note II] t4d73:
Re: [Kernel][Mar 24] Perseus

I don't understand what you mean by the processor giving instructions. Isn't that the memory's job? Anyway this is how I use all 4:

And this is the result on linpack almost every run:

You're not gonna get that result at 1.6ghz lol!

This is basic computer and how they work. Clockspeed is one thing, but there more to performance than just that. Here some basic information:

clockspeed: http://www.webopedia.com/TERM/C/clock_speed.html

MIPS: http://en.wikipedia.org/wiki/Instructions_per_second

wordsize: http://en.wikipedia.org/wiki/Word_(computer_architecture)

computer memory: http://en.wikipedia.org/wiki/Computer_memory

And it's good idea to the know difference in what RAM, ROM, and storage in regards to role with computers. This is stuff that is usually covered in any of intro to computer class. Although, probably for many of us, it's been a long time since we took those kind of classes.

Basically, what I was trying to say, and appears to have failed, is that because GN2 has four cores in it's CPU, it's going to be able preform better than other phones when only two or one core CPUs. It's just able to process more information at once.

Not that greatest analogy, but think of it this way. If you have six people needing to go from point A to B. The distance is hundred miles. Which do you think can complete the job faster. A Ferrari that can do 200 mph, which only seats 2 people, or the minivan going 65mph that can seat six. Mini van only has to do one trip. The Ferrari will have to do five trips (500 miles). Lets assume they can maintain the speeds given, the mini will take 1.54 hours. The Ferrari will need to 2.5 hours. For the Farreri to equal performance, it need to do 324.66mphs.

And in the end, when we're talking about overclocking our phones, we're really just trying to get a bit more performance out of it. And really, unless you're doubling the speed or something near there, the performance increase usually isn't very noticeable expect on a few apps where the lowers speeds more it operate well. There are a few other factors that come into play for performance, so I don't want to give the impression that clockspeed, cores, amount of ram, and wordsize are all inclusive. They just are biggest factors.

The funny part of this, nothing has really changed from ten plus years ago when people were pushing PCs to the limits and starting to experiment with liquid cooled CPU cooling projects. I remember seeing people using their freezers.

Re: [Kernel][Mar 24] Perseus

Thanks for the info. Lots of good points. I guess there are many factors that gain performance. I just try everything to see what works best. You're right though that this device is so fast there really is no need to push it any further.
[Sprint Samsung Galaxy Note II] MeetFace:
Like I said, we're not encoding ISOs or rendering large PS projects, maybe .0001% of us are. The Note II is going to be capable for quite some time.

Thanks love again for clarifying for everyone. You guys trying to compare single- and dual-core cpu overclocking & performance with the quads may want to stop OC'ing, it's a bad drug that gets you no where except for marginal cool-points with the benchmark scores.

Re: [Kernel][Mar 24] Perseus

Lol it's all good. I've been running at 1.8 now for about a month and it's as smooth as ever. Of course I was rooted, running this kernel, and overclocked the same day I got my device, so I really have nothing to compare it to but I love it coming from the epic touch. Worlds apart!
[Sprint Samsung Galaxy Note II] tpeef:
The only way I ever peg the CPU on this phone is with a benchmarking app. (I run a lot of benchmarks, as I like to check for differences between the kernels I build).

The bottlenecks in performance that actually impact my user experience on this phone are in network I/O and "disk" I/O. CPU is rediculously overpowered at two 1400MHz cores, let alone 4 1800's.

That's not to say that you won't get better benchmark results if you run it at 2000 MHz- it's to say that if somebody turned my scheduler down to a 1000MHz cap, I probably wouldn't notice for any of the non-development things I do on my phone.

As an update to the perseus-zram thing, I've been running zram perseus kernels since the question came up in this thread.

It works flawlessly- there's the good news.

The bad news is that it works flawlessly.

Let's say phone A has no zram. Phone Z has the same setup with a 256 MB zram swap activated.

Phone A and Z get used the same way, and run 20 apps as the user does this and that.

Phone A runs out of memory at app # 10 and kills app #1 to free up some RAM.

Phone Z runs out of memory at app #8 (it is using 256 MB for zram), and starts paging. It writes inactive pages out to the swap area, which takes CPU and memory bus bandwidth.

At app #15, A is still out of RAM and kills app #6 to free memory.

Z is still not out of memory because it has 512 MB of compressed memory pages in its 256 MB swap area. It is still using some extra CPU and RAM bus bandwidth.

At app #20, both phones are low on RAM and killing apps to launch new ones.

Which user had a better user experience?

They probably had about the same experience. But user Z kept more apps open longer, saving him some slow disk I/O if he went back to previous apps. User A had less CPU usage and more available memory bandwidth, which he probably didn't notice or care about.

I'm going to guess that for what most people do with this monster phone, user A is marginally better off.

On a phone where free RAM is a problem, zram is a big win. On this phone, it seems to be more of a draw.

I'm sure we'll all be using it when Android 6 rolls around and needs a gig of ram to boot up, though. ;)

Re: [Kernel][Mar 24] Perseus

My OG evo was over clocked to 2GHz for the 2 years I had it with no issues for me and plenty of my friends... and that was on a pioneer phone basically. I highly doubt 2ghz which is only .4 MHz over stock will do any harm especially if 3 year old hardware and architecture can handle a 1 GHz over stock.

Re: [Kernel][Mar 24] Perseus

Try this.

http://db.tt/B94JqdBS
[Sprint Samsung Galaxy Note II] tpeef:
My Perseus fork (with an initial goal of bringing Perseus up to Linux 3.0.71) has mostly met its initial goal. ;)

Source code here , precompiled binary here.

This kernel is just Perseus with all the patches to bring it up to the current 3.0.y version of Linux (the majority of which aren't even useful, but there's some good stuff in there).

The binary above is probably built with many different config options than the Perseus binary (I haven't checked to see). It probably also has a vestigal 64mb zram disk, which I keep meaning to turn off "next build". ;P I've only been running it for an hourish, but it seems to work fine so far, for whatever that's worth.

I will probably be continuing work on this (possibly working on getting some of the missing several commits added, or possibly trying to port in some newer code from newer versions of Linux).

As a note to those of you who are wondering why you'd download this: You probably wouldn't (though there are some relevant improvements in there). The point was more to do the work of upgrading Perseus than to create a forked binary distribution with a slightly different name. :)

For those who just want to play with zram, it will already be running a small 64MB swap partition when you boot- you can change its size like so:

you@droid> su -

root@droid# busybox swapoff /dev/block/zram0 (tells Linux to stop using this area for swap)

root@droid# echo 1 >/sys/block/zram0/reset (tells zram to free the memory used for zram0 and set size to 0)

root@droid# echo 268435456> /sys/block/zram0/disksize (tells zram the new size in bytes of zram0. Example is 256MB. Stick with multiples of 1024.)

root@droid# busybox mkswap /dev/block/zram0 (tells Linux to prep zram0 for use as swap)

root@droid# busybox swapon /dev/block/zram0 (Tells Linux to actually start using zram0 as swap)

root@droid# exit

you@droid>

I don't suggest using a large zram disk for regular use unless you actually run out of memory on this phone, and maybe not even then (see my zram post above for details; no zram disk is probably the best setting for this phone).

If you want to change it at boot time, take apart the kernel package and edit ramdisk/sbin/perseus.sh. You'll see similar commands in there.

Sorry if this has been addressed before but my S Tweaks app no longer works. When I open the app the screen below appears.

I've checked better batt stats and nothing is out of the ordinary than I've ever seen before. Only thing I'm questioning is I checked out my CPU states and it seems like core 1 stays pegged at 1.8 for 90 percent of my screen on time. All other cores are acting normal. I never paid attention to that before now though. That seem normal? I am running the 5G profile and the governor tweaks for stweaks. I am stock rooted LJC still and I'm sure a fresh wipe may be my only answer but just looking for suggestions at this point.

Almost all of the delta between users come from the I/O part of Quadrant as it's sensitive as **** and a fly beating its wings can cause enough interference to increase or decrease the scores. So please stop using that 3 year old piece of garbage on modern smart phones.

Use AndroBench for I/O, use CF-Bench, Geekbench for CPU, use GLBenchmark for 3D performance. Use Antutu for general, even though its 3D score is useless.

please help and i will try to do my best to make a great kernel for the sprint community

modules are breaking

-capacitive keys

-camera focus

I have tons of goodies in my kernel :)
[Sprint Samsung Galaxy Note II] AndreiLux:
The modules themselves are not causing any of those problems. Capacitive keys not working is because the source is incomplete, pull the Cypress drivers from another Midas phone. Camera focus I don't know about and never heard of that, maybe screwed Sprint firmwares. The modules being big is because they have debug symbols still included in the binaries so you need to set up the linker to strip them at compile time.

Sorry, and as arrogant and rude as this might sound from me, but people incapable of basic kernel debugging in regards to issues have no place in releasing a kernel, so you being so hyper about "supporting the sprint community with goodie feature" while not able to troubleshoot basic stuff isn't really a show of qualitative work. There's been a couple of US devs PM'ing me for some tips on the Cypress drivers as that's really not very obvious for people not familiar with the platform; but aside from that they did the rest themselves without issues.
