Me and humberos work as team, and build from sgt7 sources time to time.

alroger also builds from the sources on his own, but in the end when we say it's a sgt7 rom it's compiled from the sources at http://github.com/sgt7, and the same thing, but the most recent build would be mine + i merged code from cm before building.
[Galaxy Tab  Android Development] spike1985:
But I miss the overclocking tweaks of humberos in your builds, cdesai
[Galaxy Tab  Android Development] RED ZMAN:
A lot of the technical stuff is over my head, but I understand the gist of it. From what I understood before, Alroger had other modifications in his that you guys didnt, or am I crazy?

If I was looking at it wrong, then what I am reading is that you 3 all do the same version of the same rom, just compile it at different times/upload it at different times/places. So I can use any of the versions the 3 of you put out and be a happy boy with the same rom.

Thanks man. I love, absolutely love the work you all have done.
[Galaxy Tab  Android Development] cdesai:
his builds would have his kernel, and we've talked about it, and i'll merge the code into the cm kernel soon

Being as clear as i can:

Me n humberos and others started work on ics / cm9

sbradymobile tweaked the source more than the device specific stuff we did, and added new features

so, me n humberos are device maintainers, working on the kernel and device specific things

since sbradymobile did a lot of useful tweaks, we've now made it into a custom ROM, which we call as sgt7

alroger builds from the sgt7 sources because he can, and he likes doing that, and we won't stop him.

humberos builds with his own kernel, but from the same source.

my build is the latest, with the latest code from our sources as well as cm sources, and i've released it for a bunch of devices, the 10.1 and the 8.9 tabs, all variants of em

And, my pc's building for the asus tabs in the background while i write this post :)

Tomorrow would be the turn of the xoom, and a few others :)
[Galaxy Tab  Android Development] OsitKP:
Thanks for your build! Any hope to see hw buttons' leds switched off like formeкly? Now they glowing some time or (when I choose "never") they glow ALL THE TIME at at half brightness. Is it a bug or a feature? :)

@cdesay

Any chance you'd develop CM9 for wifi only version of galaxy tab p1010?
[Galaxy Tab  Android Development] sbradymobile:
Hi, I will submit an option to never show the lights. The menu button feature is not in the cdma kernel so it requires some changes to work with the new button timeout feature.
[Galaxy Tab  Android Development] alroger:
BUILDS

Thanks everyone for clarifying things.. Thanks cdesai.

I try to make this clear in my download page. I just build = download the sgt7 sources, called UNOFFICIAL, and compile it. I started doing it just to learn, and ended up doing it to help latin varients, that dont get the nightly as often.

Actually I really started cause Humberos was very busy and new fun stuff was being updated and I do want to try it all like everyone.

I keep doing it also because I want to use PDroid, and since we're talking about nightlies, there's something new everyday, and even if we wanted we couln't have a fixed recepie for PDroid... so I compile when I think there is something new and compile with PDroid patches also.

RED, I didn't help in any DEV. Keep in mind OFFICIAL is CM9 OFFICIAL, UNOFFICIAL is what cdesai started here, THANK YOU!, before even CyanogenMod could care about the Galaxy Tab.

2 Basic versions, OFFICIAL and UNOFFICIAL, that are changing constantly.. so my xx/may build might be different from humberos xx/may build just because we compiled in different times.

As sbradymobile already mentioned, all goodies that he does for tweaks and trebuchet can and might eventually go into the OFFICIAL CM9... but CyanogenMod has standards and rules. Anything new has to be aproved not only for the Galaxy Tab but other CM9 gadgets also.

SGT7 still has more tweaks than the OFFICIAL... so pay attention when you don't find something that others mention.

ON TOP OF ALL THAT... thanks to HumberOS we have kernels for latin tabs (P1000N / P1000L) and he is aways playing with things I wouldn't even imagine. And I've learned he split a separate kernel in the repos a couple days ago - OC and frequencies for example.

And remember... all experimental.

Cheers!

PS: notice the DEVELOPMEMT and DISCUSSION threads are for CyanogenMod OFFICIALs.

This bug and the discussion threads are for the brave.

PS2: I get so excited when tapatalk tells me there a new post in the DEVELOPMENT thread... and 90% of time so sad that it has nothing to do with development. If you check the threads history great stuff like USB host, battery performance, gps, wifi performance, camera fixes and all GREAT DEV news have been quickly obscured by non-dev related posts. Seems like there are 100 non-related posts to every great news in the DEV thread. And peeps that don't really follow things keep asking stuff over and over that was already announced.

Help keep the DEV thread clean... THAT's our changelog!
[Galaxy Tab  Android Development] RED ZMAN:
2 of the more helpful posts I've seen. Thanks.

SBrady, in older versions, pre 05 I think, the lock screen would support landscape and reverse landscape when the screen turns on, and locked. Now, it only shows in portrait, and the screen when unlocked is landscape it reverse landscape properly.

Also, 2 more issues I've found.

1. Graphical glitch in a few programs like Waze, with many of the in app buttons and report toasts, with Navigation bar active in at least phone mode. They are cut off, our have lines missing.

2. DSP Manager Has Stopped when connecting to a phone via Bluetooth, at least in Tablet Talk app. Everything still works though. Didn't happen pre 14 Alroger.

[Galaxy Tab  Android Development] ableeker:
Every now and then when I reboot the Tab it doesn't boot normally, but displays a screen saying Encryption unsuccessful, restart device. This is the only option left at this point. It restarts the Tab, but wipes all apps and settings, like a factory reset. Needless to say, I haven't enabled any kind of encryption whatsoever.

Oops, I flashed from recovery (as usual), and the Tab is stuck on the Samsung logo after reboot. I can force-shutdown the device by long-pressing the power button, but after restart I can't even get into recovery! (download mode is ok)

It looks like something is seriously wrong with the kernel, at least on my Tab.

Hi, Humberto! How is it going on with 3.0 kernel?

P.S. Some of russian users also have got a cycling reboot after flashing your ROM. I've made no wipe and nevertheless it's all right. :)
[Galaxy Tab  Android Development] humberos:
I am using another kernel source.

If you have my previous build then you won't have problems.

A full wipe is required for first flash.

About 3.0, I am working on.... lot of things to do!

[Galaxy Tab  Android Development] daniel.weck:
I can't get into recovery anymore, just download ;)

---------- Post added at 04:18 PM ---------- Previous post was at 04:06 PM ----------

Okay, I restored Alroger's build 23-May-2012 via Heimdall (just boot.img kernel + recovery, so I could at least regain access to CWM and attempt flashing again :) )

I've been on MTD for a while, I don't understand why Humberos' 28-May-2012 build isn't booting at all on my Tab. Ideas?

I did a new flash with restocking go GB first.

But the problem is still there, that it takes some time, until a webpage is displayed or fully rendered.

Someone else with this symptom?
[Galaxy Tab  Android Development] humberos:
So, back to your previous instalation and do a full wipe before install.

I am using another kernel source and it won't work over anothers versions.

Sources at my github.

I am sorry!

Greetings from Brazil!
[Galaxy Tab  Android Development] daniel.weck:
I understand now. :)

I am sorry that I did not realise you switched to a different kernel.

I will avoid your builds for now, as I don't want to do a full wipe. Any idea of why such a kernel change requires full wipe? Perhaps there is a more lightweight procedure for experts users who know how to manipulate partitions from the command line ;) Let me know if you can please.

Many thanks for your incredible work!

[Galaxy Tab  Android Development] spike1985:
I wonder what will bebetter on 3.0 kernel?
[Galaxy Tab  Android Development] spike1985:
Does thaz mean that I am stuck on your builds now? Will it "break" my system if I'd flash a alroger build or so if I am running your 28th build?
[Galaxy Tab  Android Development] alroger:
Heheheh.

I think this new kernel changes directory structure, permissions, drivers, sysfs... that's why partitions need reformating... full wipe/factory reset does it all.. I didn't try it yet.. but you might be able to do it without formating data... gotta try one by one..

So switching to and from this kernel requires facotry wipe.
[Galaxy Tab  Android Development] spike1985:
Meh... I should have known before...

Edit:

I went from 22nd?! Humberos to 28th Humberos without wipe... besides gapps everything went fine without wipe...

How the f***?? Any explanation?
[Galaxy Tab  Android Development] humberos:
Ok! It will works if you flashed the new version over my own previous.

The problem is who have another version (Nightly, AOKP, ...) and want install the new Unofficial HumberOS over it. A full wipe is required in this case.

I am using another kernel source.

More fast and stable.

GPU Overclock

GPU Overclock

I checked in our source and saw that we can change the GPU frequencies.

So, just download AnTuTu CPU Master from GPlay, open and select Advanced tab.

Click on GPU Control and you'll see all frequencies.

I am using it with 320MHz on all frequencies except:

200MHz => 250

100MHz => 100

Battery life is good and all functions working so fast!

Greetings from Brazil!
[Galaxy Tab  Android Development] OsitKP:
Just FYI:

I always flash nightlies, alroger's and your builds in different sequencies (MTD for sure). And I never did factory reset. A couple of times I wiped cache and dalvik-cache. And everything works OK. Probably there is another reason of rare cycling boot...
[Galaxy Tab  Android Development] humberos:
Very strange!

I have 20120528 right now but my tab won't work if I flash another build.

I need to do a full wipe so it works fine.

I will check it later.

Is there any way to get the custom nav bar as it is implemented in AOKP Roms?

I prefer using the capacitive buttons.

So the navbar is still there, but I removed the quick launch buttons and set transparency to 100%.

For me it's nearly perfect this way. The best would be if the bar is on Top.

Sorry, of course I'm talking about Humberos Rom. :-)

Thanks again Humberto!

Just to let you know, I'm testing your 28th Kernel. 1.4GHz is unstable for me, as it was in other ROMs we've tested. But I have a very stable 1.3GHz without any UnderVolting.

EDIT: Also using GPU @ 320 like you mentioned, just not for 200 and 100MHz.

Thanks for the frequency step.
[Galaxy Tab  Android Development] humberos:
I am sorry!

Now, 1.4@OC is stable for me (with all governors) ... Just confused:confused:

But I don't use this frequency (1.4) because I want to save my battery life.

I am using/testing 1.1/1.2GHz with 320MHz GPU@OC. I will report the details about this configuration.

About my repo, I don't know why we can't set it as reference in our local manifest yet. Sorry again!

I am running alrogers 20120528 build.

Based on these posts above I tried AnTuTu and it tells me that I GPU control is not available on my device.

Is that because the kernel in alrogers build is not the same as the Humberos build? :confused:

Not too worried but still, it'd be nice to know.

Gpu running at 320mhz :-) :-)

Will work on cpu clocks with humberos tomorrow, still not stable, gonna revert back to stock and implement live oc tomorrow.

@phlooke yea that's due to a different kernel

Edit: seems like tapatalk won't upload the screenshot
[Galaxy Tab  Android Development] humberos:
Yeah!

I was talking with @cdesai and he told me that 1.1 and 1.3MHz steps isn't good.

Perhaps these steps are causing some hangups.

We'll try to use stock steps and implement LiveOC.

I am sorry!

Greetings from Brazil!
[Galaxy Tab  Android Development] Monfro:
LiveOC would be great!!!

I think that also 1200 and 1400 steps (done with multiplier ) are needed.

These steps can also be a good base for liveOC, or used with liveOC 100% by people whose ram/bus/gpu are not good to be overclocked.

I think that the kernel you built on 22may was really stable.

Something merged on 28may one made it unstable, as i wrote in my previous post.

But i think that 22may kernel is a good base to start with

[Galaxy Tab  Android Development] sbradymobile:
Nice catch, I had seen it before but wasn't sure of the exact cause. I tracked it down and just merged in a fix. The problem is that the notification was being resent as it progressed and removed / added rather than updated in place.

I also merged in some fixes for the notification panel sizing that should prevent it from going out of the screen and some lockscreen changes from upstream.

[Galaxy Tab  Android Development] XenoStrat:
found a little useful tweak:

/sys/devices/virtual/bdi/179:0/read_ahead_kb

the value in that file is 128 by default (on my tab anyway)

Changed it to 1024, which made my internal SD card read speed go to 43Mb/s from 27Mb/s.

It's being reset at boot; I haven't read the following thread yet, but necessary info should be found there:

http://xdaforums.com/showthread.php?t=1010807

Would it be possible to integrate that tweak in a future rom?
[Galaxy Tab  Android Development] vanvancool:
maybe bad idea, please read this : http://yarchive.net/comp/linux/readahead.html
[Galaxy Tab  Android Development] XenoStrat:
tested read ahead =

512kb : SD.read speed = 33.6

1024kb : SD.read speed = 43.5

2048kb : SD.read speed = 43.8

speeds are mean values (benchmarked each setting 5 times).

Logical; too much read ahead kills performance on random little files access.

As Linus Torvalds states, heuristics should do the trick.

Now I'm thinking about how to assess this tweak's usefulness in our use of the tab.

- bigger readahead is better for all multimedia read (get files from tab to other devices, show images, read music, movies and so on).

- for every little file it would be less effective, but how ?

Let's take a 512kb file as example:

-default value: read 4 blocks @ 27Mb/s : 1/54 sec

-1024 value: read 8 blocks @ 43 Mb/s :1/43 sec

I've made the calculus for 1 to 8 blocks:

- 1block : 4.90 times worse for new value

- 2block : 2.45 times worse for new value

- 3block : 1.63 times worse for new value

- 4block : 1.22 times worse for new value

- 5block : 0.98 times worse for new value

- 6block : 0.81 times worse for new value

- 7block : 0.70 times worse for new value

- 8block : 0.61 times worse for new value

Thus we have a breaking point @ 5 blocks (=640Kb); the new value is better for files bigger or equal to 640kb (with one exception @ 9 block size : 10% loss).

Knowing that we're talking about 15msecs max difference per file read (on a 1 block file size); a significant perf loss would arise when the device must read more than 100 little files that are not in consecutive blocks (which would account to a perceptible time loss of a second).

I can't go further right now because I don't know the android world well enough.

- I suppose the kernel is mainly using the ramdisk to handle little "working" files (/proc?), thus no impact there (since the readahead works only for the SDcard)

- what about the system?

- are there applications reading a lot of little files on SD?

I know my use of the tab is mainly multimedia, thus I'll keep that new value as long as I don't see a problem with it.

One last argument: our tabs are not routers. Linus Torvalds talks about linux, replies to a guy that has a specific case. Comparing that case to our device's perfs, to experience the same we would have to use an application randomly accessing 24000 files of 128kb with a 2Mb read ahead, which is stupid indeed (3Gb sparse data on the SD!?!).

EDIT:

couldn't get those last numbers right by head. :)

[Galaxy Tab  Android Development] spike1985:
So? Really? What usage profile? Any OV/UV? What functions are used (3G, BT, WLAN?)? What you call "fast drain"?

For me batttery lasts a lot longer since the HW acceleration support allows me to underclock and undervolt (max 600Mhz @ -75mV) and still have a tab performing as good as on Overcome @ 1,4 Ghz for most purposes...
[Galaxy Tab  Android Development] alroger:
Thanks for the details.

I have always used either 1024 or 1536KB of cache.. did a lot of tests using SD Tools and SD-Booster from the Market and it does help in general. Now I have ROM Toolbox to set it for be at boot.

PS: That is for my internal SDCARD, I don't have an external one. Values do varry acording to type/manufacture/etc.
[Galaxy Tab  Android Development] spike1985:
Maybe it would be possible to build in a setting in the preferences for that. Or even an automatic mode? But checking what value would be best before every file access or a defined number of checks per second would cause (too much) system load as well?!
