RD01-2.1 Up

Ok RD01-2.1 is up:

PLEASE READ THE CHANGELOG (BLN should be fixed now)

ALSO I HAVE MOVED ALL NON STANDARD GOVERNORS AS KERNEL MODULES in /system/lib/modules. THIS WILL SATISFY EVERYONE, WITHOUT INTERFERING. PLEASE READ THE CHANGELOG FOR THE AVAILABLE CUSTOM GOVERNORS.

NOTE: NONE OF THE APPS WILL SHOW THEM AS LISTED. CREATE AN INIT SCRIPT AND ACTIVATE THE CUSTOM GOVERNOR YOU NEED:

E.G: (this one activates the badass governor) (see the changelog for the list or browse /system/lib/modules)

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] number16:
hmmm I tried both 2.0 and 2.1, and afterwards I get all kinds of problems. Vibration doesn't work, Dolphin browser keeps crashing ...

Somehow when I examined the /system/lib/modules I don't get all the files from the cwm flash. Upgraded CWM to latest recovery, flashed over and over, from both external and internal flash, but somehow still the same problem.

And when I reverted back to the original ROM (seanz modded UCLF5) the problems didn't go away. I eventually had to do a NAND restore.

I never had this kindda problem with any previous kernel flashing so it's weird ... any clue why?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Not sure..the only thing I can think of is that for sure your recovery whatever you had, was not executing the update scripts properly (the modules data point)..If you done a lot of flashing in between, you probably were lucky to survive until this point..Sammy's ROM releases replicate the kernel modules in /system/lib/modules (i.e. why on my stock I would delete it and link it to /lib/modules). Now, I am putting it back in /system/lib/modules BUT you have to make sure that the content is a SUPERSET of /lib/modules (which is what the update script does). The reason I am doing this is I am providing a lot more netfilter modules and we don't have enough space in the /boot partition (10MB) to house all the modules.

Thanks for your quick reply mohan ... I've been using this recovery (Touch CWM v6.0.1.0 ver 7) for a LONG time and never had issues ... if the recovery is the problem here what else would you suggest?

I also used this recovery to flash your 1.4 and 1.5 ROM and never had issues in the past, which is why it's really weird. I also checked MD5 checksum of the download file and everything looks fine!

And I suppose the flash (if done properly) should automatically replicate the files from /lib/modules to /system/lib/modules/ right? I shouldn't have to manually copy them over right?

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
I honestly cannot recommend a recovery, as my experience has shown that the recoveries seem very inconsistent on our device..You should NOT have to manually copy them. Also, /system/lib/modules should have MORE files than /lib/modules (i.e., superset), but it should always contain *all* the files in /lib/modules.

Sorry for the delay, but feature-creep always kicks in...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
You only need the updates scripts for the custom governors right? Decided to try this new update, and I used your scripts to tweak everything and it seems to be working.

By the way any benefit to removing the # sign in the optimized noop I/O? Or the one line that is running is enough and the other won't make a much noticeable effect?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Yeah, version 2 scripts (NOT to confused with Cymbaline's version number) are compatible,

except the non-standard governors zips.

Which # are you referring to?

I am removing many of the commented out settings there, they refer to the hardware (like number of physical sectors) and shouldn't be changed. I just made the scripts and then researched tunings afterward, so I only ended up changing the things that would be a benefit.

Noop is extremely basic / simple and doesn't have much in the way of tunables other than what I did. (Some of the defaults were already optimal, like allowing merges and killing the spinning-hard-disk related features. It also emphasizes a lag in the UI. Deadline-Tuned is my favorite, for performance / smoothness.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
On sky ics everything is smooth anyway so I'm just going for mainly battery and from what I researched it should be the best for it. I'm not using my phone much anyway for calls and sometimes surfing but I got my laptop with me most of the time.

In the optimized noop script most of the lines starts with # meaning they don't work, so I'm guessing they aren't needed.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Yeah, the scheduler shouldn't eat much battery, that's what I meant on the lack of tunables in Noop. There isn't much to change that would provide any benefit.

add_random uses the flash memory usage to write random bits to the entropy pool, but that adds some extra overhead, so I disabled it (the entropy pool gets data elsewhere too).

nr_requests drops the number of batch actions in half, so, rather than waiting for 128 to accumulate, it waits for 64, before processing them / executing them. Which should help responsiveness a bit.

Thank for both replies! I just thought I was missing something.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
That would be the classic symptoms of instability due to either too high of an over-clock or over/under-volting.

1.836 GHz is an extreme overclock and only really stable for a lucky few. Slight instabilities can manifest randomly. This is why I ran an excessive number of tests with A LOT of benchmarks when testing voltages for my UV profiles... Even then, I still have to qualify my results with the reminder that your results may vary. Chips do not all come off the assembly line exactly the same (which is why the phones have high voltages "stock" in the first place).

There are just too many factors involved to say "well, the only thing I changed was the kernel, so this is the kernel's fault."

To troubleshoot this, first, are you undervolting? If so, go back to defaults and try again. If not, give it a shot.

Second, how many times did you run AnTuTu on Cymbaline 2.1? If it was only a couple of times, I would hesitate to draw any conclusions as to the stability of the chip at 1.836 GHz. Dial it back to 1.782 Ghz and run the test, that level is stable for MANY people and only 54 Mhz less.

Finally, AnTuTu stresses your CPU / GPU in ways that you are unlikely to ever do in real-world use, so, if it is stable otherwise, I wouldn't worry too much about it.

I wish the battery life was better. Running a stock kernel from unnamed ROM has great battery life but no BLN. I guess to get BLN we have to sacrifice some battery.

You should be able to uc, did u say apply on boot ?

EDIT: Also if using RD02-2.2 or above change the gov. to "ondemand" from "ondemand_sammy" as Sammy's gov wont let you UC below 1.242GHz (I will confirm later). On versions *below* 2.2 (i.e. RD01-2.0 and RD01-2.1), the sammy gov is called "ondemand" (and is the def. in all versions, btw), you would have to use another gov. to go below the 1.242Ghz. Also, remember you would see the Max. freq only during boot (during init, it ramps up to max.) The next version, I will put in the hack to *not* ramp up to max in the freq. table, so we would only have one version.
