Hey, can any one of you guys help me out?

I've been running this kernel since v4, and when I updated to v6, there weren't any problems. Only recently did I start having weird problems like lag, freezing up. No clue why it started. I probably did something dumb with some software. I think I solved that by switching my scheduler from bfq to noop. It might sound dumb but my phone doesn't lag anymore even though bfq is supposed to be better for performance (right?). No lag, good performance, smooth all around. Using with OKJ RC6 now.

But I still have one issue that's been bothering me. Sometimes, probably 2-3 times every day for the last three days it has happened. I guess it's a lockscreen freeze. What happens is when I press the power button the screen just stays black. I don't think it's entered too deep a sleep because I have my CPU at 200-1200 on alicornq; also at night when it happens I can sorta see the screen lighting up a bit but it's still black, just a lighter black, meaning the screen is still on but I guess the graphics aren't loading. Only way to solve it is to battery pull and reboot.

Is this just because my phone is old/hardware issue? I only have a couple of months until the contract ends, so these cool kernels and stuff keep me occupied. I'll test different governors and see if it happens. Pegausuq/noop is very stable in my mind.
[Samsung Epic 4G Touch] Zxo0oxz:
Well, while I'm questioning the decision to open up this phone and solder a new USB port on, I've ordered 3 extra batteries and a wall charger. Not sure I'f ill continue development on the kernel, don't want to risk bricking my phone since I won't be able to odin.
[Samsung Epic 4G Touch] rangerelf:
I had similar problems, I'm on v6 cm10.1 nightlies. I solved with a full wipe and reinstalling the apps from the play store, instead of restoring them (I've never restored system apps, before someone asks).

I also got rid of all tweaks, and didn't reinstall Facebook nor xposed, just to be on the sage side.

I haven't had a freeze in almost a week now.
[Samsung Epic 4G Touch] eigokyoukan:
Oh wow, I just stumbled on your kernel today. Flashed over on DU and its really great work. I am sorry to hear about your phone! If you ever need a tester for anything else you dev, just let me know.

Great work so far.... v6 is running superb.
[Samsung Epic 4G Touch] Inane_Asylum:
I think I might give the 4.2 kernel a shake. Been hearing good things about it.

[Samsung Epic 4G Touch] wm388:
Update: working fine now. Smooth. What caused the problem was a combination of dirty CM nightly flashes, using the bfq scheduler which isn't too great for me personally, and maybe setting the min too low (25mHz).
[Samsung Epic 4G Touch] UndeadNexus:
Flashed the latest 4.3 kernel and now my home button doesn't work :( I'm running CM 10.2 Hood Pope
[Samsung Epic 4G Touch] gamepro602:
There's a fix in this or the hood pope thread, and its an issue with the kernel, just search both the threads
[Samsung Epic 4G Touch] UndeadNexus:
Thanks
[Samsung Epic 4G Touch] Zxo0oxz:
I'm sure if I rebuild it, it should be fixed now. However, I'm having trouble with my build server. Need to figure out what the guy hosting it is doing... Can't build it on my laptop since I don't have internet though :(
[Samsung Epic 4G Touch] gamepro602:
I heard that you couldn't tether directly, have you tried hotspot or Bluetooth tethering?
[Samsung Epic 4G Touch] t0mmyr:
cool, cant wait to try a new kernel for 10.2 hopefully as good as v6 was for 10.1 :)

is the usb port easy to swap? i have some spare parts of some gs2s and could maybe remove the port and send it to you, better if your local to socal
[Samsung Epic 4G Touch] Zxo0oxz:
I wouldn't really consider it easy, not on this version of the sgs2. Anyways, thanks for the offer, but I'd rather just buy the parts myself when I'm ready to dig into it. In the meantime, I may still continue working on the kernel if people are willing to test before me.
[Samsung Epic 4G Touch] Zxo0oxz:
New 4.3 release, a few minor updates.
[Samsung Epic 4G Touch] Krowbarr:
Is the issue with the home button fixed? I just flashed a 4.3 Rom. Thanks.

[Samsung Epic 4G Touch] Zxo0oxz:
I can't tell you, as I don't have a phone to test it. I believe the fix was committed though.

Edit: 6.1 released for 4.2 as well.
[Samsung Epic 4G Touch] beezie42:
Newest kernel is working great so far on 4.3 hood pope. Thanks again!
[Samsung Epic 4G Touch] kvevand63:
Running v6.1-4.2 with CM10.1 0929 nightly/OKJ, 1500/900 alicornq/noop. Smooth, no issues encountered after 10 hours of continuous multi-task use. Any chance of changelog regarding updates from v6.0? Great job, loving this kernel!!
[Samsung Epic 4G Touch] Zxo0oxz:
Off the top of my head:

Updated to Linux 3.0.98, few pulls from cm upstream, switched to gzip compression

By the way: my phone is running again
[Samsung Epic 4G Touch] eigokyoukan:
Past few hours on 6.1 has been very smooth. Great stuff.

I only had noticed this kernel a few days ago, and I have to say its just fantastic. The start up of my device has never been faster. I run a few apps at start up, and am used to waiting 10-15 secs while everything settles. On this kernel everything boots so much quicker. Thanks for the awesome work so far! :beer:
[Samsung Epic 4G Touch] Zxo0oxz:
Glad to hear it's working good. I haven't gotten a chance to flash it yet. Keep in mind, for future releases, I'm going to need people to test for me since I cannot risk bricking my phone with no USB port...
[Samsung Epic 4G Touch] Inane_Asylum:
I'll be happy to test the 4.2 kernels. I haven't had much success with the 4.3 ROM I'm testing, so I probably won't be much help there :-/

[Samsung Epic 4G Touch] eigokyoukan:
No doubt! I'd be happy to test 4.2 releases as well.
[Samsung Epic 4G Touch] jwhyte:
I'll test 4.2
[Samsung Epic 4G Touch] kvevand63:
No problem testing. I have complete confidence in your kernel, great contribution!
[Samsung Epic 4G Touch] zimlokks:
Love the new 4.3 kernel also home key bug fixed one thing is that aliconq's up threshold at mix freq should be lowered down to at least 55 amd maxed out at 90 because it causes issues wen playing music at 50mhz with a threshold of 95 but over all a perfect kernel
[Samsung Epic 4G Touch] Zxo0oxz:
As I said earlier, anything less than 200mhz is considered unstable, and likely to actually consume more power than it would at 200mhz. 200mhz is the "sweet spot" for power consumption on this chip.
[Samsung Epic 4G Touch] Clariel:
I'll test 4.2 builds as well
[Samsung Epic 4G Touch] glenesis:
Ah! I have had stability more often than not since June. Recently my gf installed Facebook, and suddenly I have to force restart a few times a day. I don't think its a coincidence.
[Samsung Epic 4G Touch] Mattix724:
Send it to Samsung for repair if you're still in the 12 month warranty period. I did last year with an E4GT that was bricked with the blue light of death and I ended up getting a brand new replacement in the box about 3 weeks after shipping it to them. This one is now out of warranty but it still works perfectly so I'm happy with the service Samsung provided.
[Samsung Epic 4G Touch] Zxo0oxz:
Yeah, I don't think it's gonna end well if they try to start it up and see Cyanogenmod on it.

Bluetooth Smart

Edit: Ah crap, looks like the S III was the first Galaxy with BT Smart chips :(

Does anyone know off hand if Bluetooth Smart (BluetoothLow Energy) is a driver or hardware (or both) upgrade?

I was reading about the difference between 4.2 and 4.3 and it said 4.3 was Smart ready. It also said the new Nexus 7 and Nexus 4 were smart ready, so I didn't know if they just had the new BT chip.

If possible, using the BT Smart driver would be awesome since my new heart rate monitor is BT Smart.

I'll go do my own research, but I just wanted to get y'alls thoughts.
[Samsung Epic 4G Touch] Prestige_DOPE:
Yo. Im getting mad battery drain with the kernel but i like the fast charge and the USB charge. Anyway to stop the draining? At school today i went around with my data off all day and it only drain significantly when i was actually using the phone. I got on my bus with about 76% after texting for about 20mins and listening to music the whole 40mins I was down to 39 when i got home. THATS ONLY 40MINS
[Samsung Epic 4G Touch] Inane_Asylum:
I'd install BetterBatteryStats to find the root cause. Last time I had drain like that, I had accidentally toggled 4g on. This kernel hasn't caused me any significant strain at all, so it's most likely your configuration or a rogue app.
[Samsung Epic 4G Touch] thedarksavant:
I completely agree on the rogue app. I had terrible battery life with The Gentleman and this kernel, but I did a clean wipe and am slowly adding back my apps. So far my battery life is the best I've ever gotten.

Facebook, Google Hangouts, or anything that wakes your phone or notifies you.

You could also try carat: http://carat.cs.berkeley.edu/

It did help me once find battery draining apps.

One patch is to install a battery save app that disables notifications and radios.
[Samsung Epic 4G Touch] wm388:
I'm getting amazing battery life with this kernel. Music on the bus and school and music in the gym... 16 hours and some screen time (maybe 1 hour) I can be down to around 49 percent. I disabled a bunch of stuff like autostarts, and also greenify and data off when sleeping
[Samsung Epic 4G Touch] Zxo0oxz:
6.2 released, only change is Linux 3.0.99
[Samsung Epic 4G Touch] Inane_Asylum:
Thanks. This update fixed the navbar backlight bug in Dirty Unicorns.
[Samsung Epic 4G Touch] Zxo0oxz:
Yeah, each build will also sync up the ramdisk to whatever's default in the latest cm tree...
[Samsung Epic 4G Touch] gamepro602:
Small issue with the 4.3 ver. The soft key lights won't turn off, the last build they stayed off.
[Samsung Epic 4G Touch] Zxo0oxz:
I can try my best to take a look at it, but I still haven't even touched 4.3 personally. I'm thinking about maybe making the jump. What's the current state of cm10.2? Also, problems like this aren't really my problems. They get pulled in from upstream.
[Samsung Epic 4G Touch] hakcenter:
Broken lol
[Samsung Epic 4G Touch] Krowbarr:
With 6.2 version soft key lights now stay off where they didn't on 6.1. I'm running Dirty Unicorns 4.3. Great Rom. It's all good:D

Well I'm not running the LATEST build of CM, im still waiting for the official 4.3 nightlies, hopefully. They'll Be out soon :cool:
[Samsung Epic 4G Touch] Zxo0oxz:
Well trust me, If I switch over to CM10.2, you better believe I'm too impatient to wait for dastin to churn out builds, so I'll be making my own nightlies. :p

Besides that, I don't believe we'll ever get nightlies unless we can get WiMax working.
[Samsung Epic 4G Touch] thedarksavant:
Check the Hood Pope thread for verification, but I doubt 10.2 will ever be official for our device.

As long as Samsung keeps the kernel and driver code for the processor closed source, it can never be official.
[Samsung Epic 4G Touch] :
Testing out the usb charging via computer. So far it's actually charging as if I'm charging it via a wall charger. ^.^
[Samsung Epic 4G Touch] ps3hacker3:
Hmm well I'm running the latest slim beta 2 of 4.3 and will take a stab at it for you and let you know if it does flash over hang tight
[Samsung Epic 4G Touch] Zxo0oxz:
That was honestly, my main reason to start working on a kernel for this device. Tethering is my only form of internet and it bothered me that the battery died when I was tethering via usb, so I set out to find a solution. Thanks to the awesome developer of the Siyah kernel, I was able to find a patch that made the charge rate configurable!

If not, I've just about got the source sync'd up on my 4.3 branch, so I'll have a 4.3 specific build out tonight or tomorrow.

Edit: Good to see people are trying it I'll have some nice new builds out sometime tomorrow, and abadasstanker69, as soon as I got out of the office, gps was working flawlessly for me on cm10.1 nightlies. You may want to try again :)
[Samsung Epic 4G Touch] comptonhubbard:
seems to be working I haven't had any problems. I o/c to 1600 just for kicks....no problems, yet.

edit...phone locked up once I turned on gps (no satellites found) had to restore nandroid. Could be related to o/c to 1.6

Nice can't wait to play with this good to see more kernel action thanks for your work my man
[Samsung Epic 4G Touch] Zxo0oxz:
No problem, figured the only custom kernel we had was just some systcl tweaks and a couple scripts, so I tried my hand at contributing. I'm admittedly pretty new to first hand Android modding, but I'm pretty good with all things Linux.
[Samsung Epic 4G Touch] hakcenter:
you talking about the lz ? i sorta noticed that and i just don't want to waste a lot of time on it.. but i have some major pegasusq tweaks you can borrow from my repo, just commit the whole gov file, it'll knock your socks off.
[Samsung Epic 4G Touch] ps3hacker3:
Just going to confirm that it doesn't boot on 4.3 it bootloops at the slim logo

Running rooted stock, no additional tweaks.
[Samsung Epic 4G Touch] LucentBirch:
I've booted into Revolt no problem. Will update after full cycle and recharge. Though it looks like the cpu use time for Android OS will be high just like LZ. I don't know enough to know why but it happens with my phone, not sure about others'
[Samsung Epic 4G Touch] beezie42:
I too noticed this. My android os is always high after flashing lighting kernel. Sometimes on stock kernel to after the battery drained to about 50%. Ive used cpu spy and bbs to figure it out but to no avail.
[Samsung Epic 4G Touch] LucentBirch:
Just froze while browsing flow for reddit...
[Samsung Epic 4G Touch] Zxo0oxz:
I haven't looked at my battery usage in quite a while, but I think that's a known issue Cyanogenmod kernel as well. As far as I know they're trying to find a solution.
[Samsung Epic 4G Touch] Zxo0oxz:
New build posted, mostly dynamic fsync tweaks courtesy of faux123. 4.3 build will probably be posted later today.

[Samsung Epic 4G Touch] LucentBirch:
Should this kernel have a different boot screen (even the right word?) Or is it also the blue lightning of lz?
[Samsung Epic 4G Touch] :
From what I learned. The High Android OS being on the top of most battery used is the fault of the smdk 4412 kernel. There was a fix submitted in the gerrit that should help that.
[Samsung Epic 4G Touch] Zxo0oxz:
If you mean this one http://review.cyanogenmod.org/#/c/46992/

This kernel has it, didn't seem to have fixed it.
[Samsung Epic 4G Touch] gamepro602:
I thought you needed those things for stable and RC builds, even without those things you can still have nightly builds
[Samsung Epic 4G Touch] ktempleton:
I doubt that's what is preventing nightlys just like I doubt the wimax not working would stop it since that was removed from the source by Google

sent through the worm hole from a galaxy far far away!!!!
[Samsung Epic 4G Touch] thedarksavant:
Sorry, looked into it and I confused stable with official.

We might get official nightlies but not stable builds.
[Samsung Epic 4G Touch] Zxo0oxz:
kk
[Samsung Epic 4G Touch] NavalFluff:
Quick question. I remember that lighting zap messes some thing up when this kernel is flashed over it, so if I wanted to use this kernel on a rom that already had LZ baked in how would I go about that?
[Samsung Epic 4G Touch] gamepro602:
Delete the in.itd folder in system

I have been experiencing a couple of lockups similar to what someone had a couple of pages back. I have times when I go to turn on my screen and it stays black. I have to hold down power button to reboot. It's slightly annoying, but I don't really want to go back to 4.2.2...

[Samsung Epic 4G Touch] beezie42:
Same here. Some days I will only have it happen once. Today on the other hand it happened seven times. It also makes my battery stats all wonky. Must still be a kernel issue?

[Samsung Epic 4G Touch] wm388:
+1, happened to me today. Kind of annoying, because of reasons. Although it tends to happen less after a while, letting the new kernel flash "settle", I guess. I'll just wait a week and it'll probably stop happening.

Flashed v6.3-4.3, so far so good. Also using bilgerryans above posted script also. Just a note; remove the commas between the sets of digits within the semaphore values in the kernel script or the values will not update correctly. Make sure to leave a space in between each set. (500 512000 64 2048).
[Samsung Epic 4G Touch] Zxo0oxz:
I'd rather you not use his scripts while testing the kernel. Its supposed to have those values built in. Like I said the semaphore values have been excluded for now, so if this build isn't that stable I'll try those as well.

[Samsung Epic 4G Touch] kvevand63:
V6.3-4.3 running with no issues for the last 8 hours. Flashed to Hood Pope 100113, no tweaks. SIO/Alicornq 1500/800. Btw.. no problem with touch key lights not turning off. Had no issue with such on v6.2-4.3/Hood Pope also.

It's a DU thing from what I can tell.

We'll trial this testing release for the next day or 2, if all goes well, I'll merge in a bunch of his tweaks. Also got some general updates straight from google and ARM pending to be merged.
[Samsung Epic 4G Touch] ktempleton:
I can help you get the data working
[Samsung Epic 4G Touch] Inane_Asylum:
So far, yes. The only issue I'm having with it is the backlight issue stated before, but that seems to be ROM-specific. I'm about to flash the recent DU update, so hopefully that takes care of that.
[Samsung Epic 4G Touch] beezie42:
I'm almost positive it is working better. I normally have at least one freeze up or reboot while at work.

Today I was able to do my overclock and multi task. Nice and smooth as well. No reboots at all. I'll report back tomarrow. Hopefully it all goes well. Thanks again!
[Samsung Epic 4G Touch] Zxo0oxz:
I'm on virgin mobile if it helps. I spent a few minutes going through the Hood Pope thread last night, not finding anything relevant. Toggled Data/wifi/airplane mode several times. After that I gave up and reverted to a month old backup. I guess just shoot me a PM, as to not clutter up the thread.

I guess while I'm waiting for that, I'm gonna go ahead and compile an up to date version of 10.2.

Edit: by the way, thanks for the input guys. I'm glad this small tweak seems to be fixing our problems. It's likely just a bandaid for a bigger underlying problem, but if it works I'm not gonna complain.
