I'm on your latest experimental build and it seems like sometimes the screen goes crazy and doesn't register my touch and it didn't do this on the previous experimental build.just letting you know in case it's something you can fix. This is only on certain part of the screen btw

forgot to mention im on ICSCrewD 1.6.1 and also i just tried to go from exp to regular and my phone wouldnt go into recovery or get past the splash so i used odin and flashed zedomax's kernel to fix it. it did the trick thankfully
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
More details?

I had this happen once immediately after a reboot while media scanning was still going but not since then - assumed the CPU was just too busy.
[AT&T Samsung Galaxy S II SGH-I777] Nick281051:
I edited my post with more information because I realized you probably needed more, but I did just try the regular standard Version and it's still there, IM trying to get into Swype and I can hardly use it now and sometimes I can't pull down my notifications, I hope that's enough info

okay maybe I was wrong maybe this is a rom thing because I reverted and it is still occuring
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
I'm on the latest Icscrewed ROM as well and haven't seen any of the screen/touchscreen issues you mentioned, Nick. Using 1/2 exp, wake lag is gone. I'm not noticing any reduced responsiveness of the touchscreen. In fact, it's just as responsive as the previous builds. No problem with notification pull down at all.

Great work here Entropy, thank you! :-)
[AT&T Samsung Galaxy S II SGH-I777] Nick281051:
I have no idea what's causing this then >.<

Now it seems to be working okay, ugh tech can be a fickle ***** lol
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Are you plugged in by any chance? Power supply noise can sometimes really FUBAR the touchscreen.

I remember I got a big scare when I first got my Infuse - I tried to charge it by connecting the wall power supply to an inverter. The touchscreen became useless until I unplugged.

Didn't occur with any other method of powering the phone.

Entropy,

Sorry for bugging you on this again.

I just flashed the 01/02/12 exp and lsmod doesn't show tun and the vpn connections app is still fc'ing :-(

Did you forget or am I doing something wrong? Can I just copy the tun.ko from somewhere to /system/lib/modules and modprobe it manually? Or is it there and I am not doing something right?

Thanks again for your awesome kernel. :-)

As far as the touchscreen issue goes, you can see the effect the charger can have if you play with the trace line in swype. In my case, plugged in makes the line get slightly jittery, unplugged it is smooth as butter.

Loving the new update though, no problems here!
[AT&T Samsung Galaxy S II SGH-I777] kennonk:
I used to have this same problem on the Captivate with 3rd party chargers. I assume it has something to do with voltages but if I ordered a wall charger that said it was for the Galaxy S I wouldn't have the problem. Old Blackberry and a plantronics wall charger I used to use gave me fits with touchscreen problems. This morning I read email, sent one email, and caught up on twitter stream with phone plugged into wall and didn't notice any problems yet on the 01/02exp.
[AT&T Samsung Galaxy S II SGH-I777] dandrumheller:
Running 01/02/12 release over jivy's ICScreweD 1.6.1. No noticeable decrease in screen response during normal use (was on 12/21 exp. Release included in the ROM). If I understand correctly from your post on release of 0102, the reverts should eliminate the lock screen lag some of us were seeing on 1212 and 1221. That appears to be the case for me anyway, after a few hours of use I have not experiences any lock screen lag.

Thank you for your continued awesome work on this device!
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Correct, the reverts should fix the touchscreen wake lag some people were having.

Touchscreen performance when charging probably depends on how "clean" the charger's output is. Cheap chargers are likely to be worse. Putting a filter capacitor on the charger output, or clamping a ferrite around the charging cable might help.

Monoprice has cables with built-in ferrites and heavy-gauge wire for power and ground:

http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10303#1030307

Note: For wire gauge, lower numbers mean thicker. I have many of the 28/24 gauge (I believe these are 28AWG for data and 24AWG for power) cables with ferrites - they are great.

DO NOT buy their "1A" car chargers - they are good for 300-400 mA at most!!!! The only products from Monoprice I've ever been disappointed with.
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
A question about the update3 changes: without studying the changesets in depth, it appears that one of the sources for cpufreq.c is replaced with cpufreq_high.c iff a define is set in the config (commit titled "Samsung GT-I9100 Update3: S5PV310-specific arch/arm changes".) (the config changes, if any, are in another commit set that I haven't gotten to yet.)

If the new cpufreq_high.c is being used, does the UV_mV[] array being used for voltage control also needed to be ported over?

On the other hand, there doesn't seem to be much being done in the new cpufreq_high.c that you haven't already done in cpufreq.c in past changes.

take care

[AT&T Samsung Galaxy S II SGH-I777] Alucardis666:
Phone feels snappy and very responsive with the latest exp update. Thanks again
[AT&T Samsung Galaxy S II SGH-I777] :
Im still running 12/1 DD since 12/8 and 12/12 didnt like my phone. I should make the jump to see how 1212 reacts.

Edit: Updated and man is this thing more responsive now! Ive rebooted twice just to confirm and its definitely faster, smoother and more responsive... at least in comparison to 12/1 DD. Im using Go Launcher EX and Widget Locker (lockscreen) and there is NO lag or loss of response time whatsoever! Freaking great job Entropy!!!
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Good question - The update3 sources include support for the Note, which supports 1.4 GHz stock. Apparently, they included a fairly new cpufreq architecture to handle this, I am not sure why they use a completely new file.

Gokhanmoral was using cpufreq_high as his base for a while but is using regular cpufreq now, with the "classic" modifications. I haven't had time to investigate why - but it was definitely a lot easier to keep using cpufreq.c than to port things over to cpufreq_high.c

However you might want to look into people working with cpufreq_high.c, as that might be more architecturally similar to the Tab Plus tree you're working with.

One thing to note: I think straight I9100 update3 sources will not properly compile for an I777 target - the decision to revert the touchscreen driver was 75% motivated by laziness combined with the arch/arm/mach-s5pv310 touchscreen stuff NOT building properly. It's broken for CONFIG_TARGET_LOCALE_NAATT. So this means that porting I9100 kernels other than Siyah may need a bit more work than just defconfig changes as i thought previously.
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
My impression is that the TabPlus sources are the latest iteration. i777 (and original i9100) code appears to max at the 1200MHz freq; the update3 code has 1400 processor support in a seperate file (odd) and its controlled by a preprocessor directive; and the tab plus code appears to fold all of it together into a single arch controlled by processor flags and determined at kernel init. With the tab plus code, I was also able to take advantage of a defconfig flag to just turn on overclocking. (I almost felt dirty taking such an easy path.)

(sarcasm: ) Anyway, I'll stop posting about actual development here in the development subforum. I might get an infraction for it. ;) (sorry, I couldn't resist...)

Take care

Gary
[AT&T Samsung Galaxy S II SGH-I777] :
I see what you did there... :D

Also, if the Tab Plus really is the latest code and it does seem to wrap it all up in one, could that be brought over to the i777? If so, then overclocking would be easy as you said it was for the Tab Plus and that would be really awesome.
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
What's in-place on the i777 works, so I wouldn't "fix" it. There are a few other platform differences that would have to be resolved.

On the other hand, I wouldn't be surprised if the ICS kernel sources for the i9100/i777 come closer to what we see on the p6210. I keep forgetting the "real" kernel version of linux-3.0. 2.6.37? .40? GB is .35 and HC is .36.

BTW, to keep this properly on topic, I'm finding the DD kernels stable enough that I'm selling off my iStuff. (No offense to android die-hards, but I've always found apple stuff much more stable than android.. until this i777.)
[AT&T Samsung Galaxy S II SGH-I777] :
^^ I agree. This new update has been the best kernel that I have ran yet on my phone. Unless some other big plans are in the works, this is going to be my DD for awhile!

2.6.40. (I didn't express myself clearly - I was trying to ask what version it was before Linus decided to change the major number to 3.) It doesn't really matter, but I get hung up on details sometimes.

We spent what seemed like years on 0.99 (especially 0.99pl15) and then we go from 2.6.x to 3.0 with nothing more than a trivial patchset.

[AT&T Samsung Galaxy S II SGH-I777] Peaster111:
Entropy,

Flashed 01022012_exp shortly after you posted it. This latest version is all good. Reverting to the I777 touchscreen drivers brings the touch back to like the 12082011_exp kernel.

The only issue I see is that you cannot unmount a USB device when using an OTG cable. The important part is that it mounts. This really minor issue has been present since at least 11132011 kernel (it's the oldest one I still have a copy of)... so I guess I really don't care :rolleyes:
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
At some point I'll get an OTG cable - but unfortunately this is a difficult thing to get data on without and a fairly niche feature.

If it goes back to 11/13, then it isn't the I9100 update3 changes... the first of those was committed 11/30, and USB host changes weren't until 12/18. (These are commit dates to my source tree, not release dates.)

May have never worked...

[AT&T Samsung Galaxy S II SGH-I777] jsmith8858:
It definitely used to work, though I also don't recall exactly when it stopped working. (I believe in this thread someone mentioned it shortly after the kernel release) Maybe he meant 11/30, not 11/13?

EDIT: here's the post that (vaguely) reports an issue with USB Host unmounting.
[AT&T Samsung Galaxy S II SGH-I777] Peaster111:
Maybe so... It has always mounted, I couldn't say on unmounting. I wouldn't loose any sleep over it.

Thanks for asking. I double checked it was the 11/13 release. There wasn't an 11/30 release. It would have to be even older if it worked at some point. That post was referring to the same... mounts OK but does not unmount.
[AT&T Samsung Galaxy S II SGH-I777] desiromeo719:

I am getting horrible battery life with this latest kernel. Dropping at about 6% an hour in idle state. Anyone else seeing this?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No.

If I had severe battery drain problems attributable to the kernel, it would never have been released.

Reports like this are useless without data - what firmware are you running on top of the kernel? Have you bothered to run ANY of the diagnostic data collection in the Known Battery Drainers thread in General?
[AT&T Samsung Galaxy S II SGH-I777] tedkunich:
Entropy,

Have you or any of the other devs looked at the SmartAss governor for the i777? Coming from the HTC Aria, it was one of the better balances between responsiveness and battery life (not that the i777 is lacking in either). Don't really know if it is even applicable to this processor. Just a though....

Peace,

T
[AT&T Samsung Galaxy S II SGH-I777] dandrumheller:
There is quite a bit of discussion early in this thread that outlines Entropy's position on oddball governors in general and smartass in particular. Unless something has changed since then, the short answer is: smartass isn't going to be included in this kernel.

Coming from an Aria myself (where I ran smartass almost exclusively) my opinion is that it is completely unnecessary on the i777, and conservative governor gives plenty of performance, at least for what I do
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
The interesting thing is - As I read more about "lionheart" that everyone is raving about now, it's just netarchy's conservative tuning patch passed off as the other dev's own work.

Netarchy's patch was one of the first things I put in...
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
I've been playing with those tuning numbers both on the i777 and the tab plus, over the past week. In my head, I've formed three sets of impressions:

1. ondemand with whatever tuning number provided by the kernel (80 up)

2. conservative with tuned numbers (35/50)

3. conservative with my own numbers (30/80)

I got the very unscientific impression that case #2 (conservative/35/50) was acting more aggressive than case #1 (ondemand/80) Looking at the 'time in state' numbers in SetCPU seemed to back that up. (Again, this was not a controlled test and could have been influenced by dozens of factors.) #3 (conservative/30/80) seemed to average a slightly lower processor speed than both of the other cases.

Perhaps I'm getting old and slow myself, but I don't "feel" any significant differences in using the phone in any of the cases. (My

The purpose in typing all this? Perhaps it's not too terrible an idea to have differently named governers that represent different tweaks. If "lionheart" is nothing more than conservative/35/50, it would allow putting the conservative defaults back to 20/80. Then, a user could set this 'lionheart' as the default governer and have setCPU drop down to basic conservative with screen off.

(I'm completely avoiding the issue of someone passing off someone elses work as their own...)

Take care

Flash the stock kernel using Odin or Heimdall. Since this kernel autoroots the system image, you'll retain root.

Then flash this kernel using the method in http://xdaforums.com/showpost.php?p=18219020&postcount=72

You may need to add "su" between "adb shell" and "dd" when on a stock kernel with rooted system.

Then always flash using CWM or the method above from then on.

The ! screen is triggered when you flash a non-stock kernel in download mode - and it's only triggered when flashing using that method. The warning screen "remembers" what you last flashed in download mode, but isn't aware of anything you've flashed using another method.

Good news: The BLN patches from Ninphetamine applied (mostly) cleanly - manually finishing the merge wasn't hard. They seem to work, except:

Bad news: Something inhibited deep sleep on my phone for a good portion of last night. Drain was normal for about 2 hours then the battery started draining rapidly. Right now I'm suspecting that BLN is responsible for this. If it is, it's going into the "long term" bin of features. ("long term" instead of "unplanned" because at least it didn't crash like it did on the Infuse.)

Flashed your stock kernel from your other thread with heimdall (from terminal in Linux) - this gave me back the original boot splash with no warning triangle

Then extracted this threads kernel from the zip and adb pushed it to sdcard

But when I attempted this command

adb shell dd if=/sdcard/zImage of=/dev/block/mmcblk0p5

I got a permission denied and instead of trying to figure out why I just ran

su
dd if=/sdcard/zImage of=/dev/block/mmcblk0p5

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
One thing that really improves things in terms of user "feel" is that the minimum polling interval of the conservative governor defaults to fairly high. This can't be overridden with tweaks - the key part of netarchy's patches is to significantly reduce the interval (increase the frequency).

For example, I believe the lowest interval of a non-patched conservative governor is 100000 us = 0.1 sec = 10 Hz polling rate. So even if the governor ALWAYS triggers an "up" event, ramping from 200 MHz to 1.2 GHz will take 0.4 seconds (4 steps - 500, 800, 1000, 1200). Netarchy's patch reduces this to 25000 uS = 0.025 sec = 40 Hz. So the same ramp will take 0.1 seconds - THIS is where the main gains of his patch kick in.
