Tried that now, but still it freezes when im doing a benchmark.

Whats that about it might be because my phone is not able to take overclock? I have searched the tread, but cant find answers. Thx for the help mate..
[Galaxy S II Original Android Development] gokhanmoral:
Yes :) and you are the first one to realize that. 5 is too low for me and the kernel already supports changing it by using tegrak's application.

8 is fine with me, I just noticed that it is a bit less sensitive ;).. Also I read somewhere I should play with BLEN value if I have lag while on charger, but didn't find time yet.

I just tried my ftdi-device at home (which also did not work with 1.8, the one I got working is now in an experimental setup at my university :( ) and it is still not working:

http://pastebin.com/jVb3Bmbi

However, this device is a bit more special as it needs more power (I connect it to a 4 port hub) and packages two ftdi-chips.

This is how dmesg looks like on a desktop:

http://pastebin.com/ZqM1jrBt

As you can see, the device appears to package some kind of hub itself.

Maybe you encounter a similar problem?

As of your mouse: I guess the wireless-adapter supports mice and keyboards. Maybe it needs a special module. Did / can you also check this adapter on a linux-machine?

I will give you bfs in 2.2 beta because I am out of options to make our devices unstable :p

It will not boot for the first release and the thread will make at least 10 pages of rating if not more... all those hundreds of posts will tell us that the kernel doesn't boot and nothing more. Maybe some will tell that they are done with this kernel and they will happily notify us that they are going to use another kernel. However as soon as people start to leave positive feedback about bfs they will ask about the quadrant scores :)

Well.. Bfs will be fun :D

How do you think guys will be better for the battery:

1. To stay with version 2.0 of this kernel which accepts lower voltages with conservative gov. or

2. To use new v2.1 RC2 , to rise voltages (because previous lower voltages don't work with it) and use lulz gov.

With other words - is there some advantage of the last version, which can compensate the higher voltages?

Thanks
[Galaxy S II Original Android Development] tolis626:
You can't make our devices unstable anymore?Worthless prick.I'm switching to AngeloM's kernel. :p

Anyway,that was exactly what I was thinking.As soon as you enable BFS,let me wish you a happy 1000 pages.Also,user requests will require you to fix their coffee machine's IO schedulers.I think SIO will have the best caffein/volume ratio. :p

Oh,I'm still waiting for busfreq control.I've found the perfect OC/UV values for both my CPU and GPU,so it's the bus' turn to get OC'ed.After that,who knows?Maybe we can unlock a new CPU core. :p :D

BFS is worthless - in the entirety of that scheduler's existence it has only ONCE in its entire history been proven to provide better performance than the mainline process scheduler, and in that one case - the mainline scheduler got fixed in the next release. (That specific case was multithreaded x264 encoding) It served its purpose, now it should die.

The BFQ I/O scheduler is a different story - that may be beneficial, but I believe gokhan already has that in.

I think it was TheRealWells who insisted on BFS,right?I don't remember exactly,but even he stopped asking.

Anyway,I prefer CFS low latency patches to BFS and I think they are already built into the kernel.BFQ...Well,I'll pass on that one. ;)

I'm running it right now after flashing rc2; came back to figure out the details on it. Feels responsive compared to other "conservative" governors. Similar quantifiable (for what Antutu is worth) results to on demand at stock MHz. Most importantly it feels good.

From things I've read sio is quite popular, and deadline. To be honest I'm not that advanced to notice the differences in what they do so just sticking with sio.
[Galaxy S II Original Android Development] :
Well I believe BFS is not worthless until we test it and see if it is worthless.

Also by this you are stating that morfic kernels on Nexus S are worthless while they outperform all other Nexus S kernels and mordfic is not building anything else than BFS kernels.

I understand what you are stating, but would still like to be proven I am wrong.
[Galaxy S II Original Android Development] CA3iR0:
When benchmarking, i get more score when using SIO, so i use it everyday. It think it's the best for perfomance, but i dont know if it is the best for "battery-saving" (mine's lasting for two days with a loooot of use)
[Galaxy S II Original Android Development] gokhanmoral:
I am not an expert on i/o schedulers but I think noop should be better battery-wise because as the name states it does nothing :)
[Galaxy S II Original Android Development] nikzDHD:
And also more suited for solid state drives, some cases outperforms sio and commonly chosen if sio not available from what I've read.

Below from no frills thread:

Q: ... can you translate it into layman terms?

A: A-yup.

CFQ: good if you have a multi processor (we're not talking dual core... much many more cores...), multi "card" system. We don't. 'nuff said.

Deadline: fast, fast, fast, but maybe one of your services will "clog" all the writes while your gmail is waiting to open that email you want to read. And maybe not.

NOOP: who said Deadline was fast ? NOOP is "the fast". (NOOP = NO OPeration = nuthin' to do... ). Good if the optimization is done at the hardware level. 99% of our devices do.

Anticipatory: surely our devices have small and slow "disk" subsystems, so maybe it's worth a shot.
[Galaxy S II Original Android Development] gokhanmoral:
I agree that if there is nothing to schedule noop should be the fastest. our sgs2s have flash storage and the seektime is near0.

the difference is only noticeable when you have more than once process having io requests.

in siyahkernel deadline, v(r) and sio already have fifo_batch set to 1 which makes them treat all requests as one (doesn't have to be sequential) and makes them faster for flash devices because we do not have seek-time...
[Galaxy S II Original Android Development] frogman:
No hassle man.About battery not to sure yet i know this dosen't answer your question.I'm still testing stuff at the moment.However i read in another thread that noop is surpose to have good battery.I can't find the link i had to that.I have posted a link to knzo thread on governors and I/O schedulers(just scroll down to I/O scheduler) .You may already have read this .However it still wont answer your battery question so you'll have to do some more reading and testing.Hope this helps.

js tried install siyah for 2-3 hours. seems pretty good kernel. :)

i browse in set cpu, quite a lot of governors.

im looking for governor that give lagfree experience but still with good battery life.

any suggestion?

i tried smartassv2 and brazillian wax but got a lag.

lagfree, ondemand and ondemandx (seems hybrid between ondemand and smartass) pretty smooth.

how about luzactive, savagedzen and the rest?

thanks
[Galaxy S II Original Android Development] Rockin_Zombie:
lag free experience and good battery life are completely the opposite of each other. Lag depends on other stuff too, how many apps you are running in the background, how "simple" your rom is etc etc. Smartassv2 lags with me too, lulzkernel has been pretty good so far. "Lagfree" is really good as it shoots upto the highest frequency quickly, but battery will drain very quickly. You can stick to lulzkernel for a couple of days and see if it works for you.

Have you been receiving posting training from Master Hacre? :)

---------- Post added at 02:44 AM ---------- Previous post was at 02:31 AM ----------

So far, every time BFS has gone up against the mainline scheduler in any way in a proper test, it has proven not to provide a single benefit. The one exception was early in its life, when it, combined with x264, exposed a regression bug in the mainline scheduler. Multithreaded x264 encoding is the ONLY workload I've ever seen where BFS conclusively beat the mainline scheduler - and the mainline scheduler was fixed in the next kernel release after that.

The example you give is a classic piss-poor unscientific example. I said nothing about Morfic's kernels. Show me an example of a Morfic kernel that performs great and another kernel that doesn't perform great, and the ONLY change is BFS vs. mainline scheduler.

Saying BFS is worthless does not, in any way, say Morfic's kernels are worthless. I've talked with Morfic myself, there are some very valid optimizations he does, one of which I have put in my kernel series already, and another of which I'll be putting in once I've finished putting a bunch of other stuff in and it's stable. (Diddling with compiler flags can cause stability problems - so I'm not doing it until I've gotten a bunch of other stuff done.) Morfic does a ****-ton of other stuff in his kernels which have potential performance improvements. BFS, however, is not one of them.

So - shut up unless you can show me a clear A/B comparison of a kernel with BFS vs. a kernel without BFS, with NOTHING else changed. Morfic's kernels are NOT a valid test case unless you can grab yourself a Morfic kernel with BFS disabled and no other changes of any sort.

This is a classic example of why XDA users are, on the average, worthless. "BFS is great because Morfic's kernels are great" has to be the worst logical argument I have seen in a long time.

Basically, you are wrong until you can prove yourself right - show me a workload where BFS outperforms the mainline scheduler and NOTHING else in the kernel has changed. Good luck - I've followed BFS on and off for a long time, I even ran a BFS kernel for a while, because I did my research and I happened to be running the only workload in the entire history of that scheduler where it had been proven to outperform the mainline scheduler (multicore x264 encoding) - and as I said, even on that workload, it no longer provides any performance benefit and has not for close to two years now.
[Galaxy S II Original Android Development] :
@Entropy512

Thanks for the post. And yeah, I am worthless XDA user, I agree.

I am worhless for the last few years because I don't know how to build my own kernel and have to use other people great kernels (mostly BFS). I,am worthless because my experience with BFS kernels, as a user, is worthless compared with your knowledge as a developer (and I am not sarcastic at all).

There was much more in my statement than just: BFS is great because Morfic kernels are great which you failed to see.

If and when Gokhan builds BFS kernel with same parameters and it performs worse than CFS I will bow down to you. I do admire your knowledge, but not your attitude.

Also if you want a test case, there is Netarhy BFS & CFS kernel for Nexus S. I don't have knowledge to give relevant comparison as a worthless user.

In the meantime, I will keep using Siyah on my SGSII whatever it is CFS or BFS.

And I am out of this thread. If my end user comments are not helping make Siyah a better kernel and my observations are not scientific I better shut up.

[Galaxy S II Original Android Development] psychoid:
i think you should reboot to recovery mode if you want to install a zip file (if you have the zImage of the kernel, then yeah you can choose flash a kernel. if you want to do that then you should extract the zip file first until you have zImage) .. after u already boot in recovery mode.. choose " install a zip from sdcard " cmiiw.. and for removing the yellow triangle.. you can read here

oh i thought you are going to build a house :D
[Galaxy S II Original Android Development] vickpayne:
1.Use flash a kernel

2.There are lots of problems with criskelos rom

3.You can't remove the yellow triangle unless you restore a secure kernel,which you probably won't so you will just have to get used to it
[Galaxy S II Original Android Development] fenomeno83:
@gohan: can you change your frequencies management to use less higher frequencies? I used speeemod kernel and use a lot 500mhz, but phone is very fast. So, i prefer your kernel for many reasons, but if use in normal use lower frequencies will have more battery but no performance degradatoon.

Then, i think you can use by default 100mhz as lowest frequencie, because works very fast with lulzactive governor.

And than, i read governors comparidon and speak very well about minmax governor..i don't know nothing compared to lulzactive, but will you insert it?

@all: have you more details and comparisons for sio scheduler in comparison to others, in terms of battery and performance? And for governors, what do you think about lulzactive in terms of battery?(performance are very good)
