[Q] Captivate rom derived from SGSII?

I tried looking for this, but wasnt able to get any hits.
Is the hardware between the SGS and SGS II so different that a stock rom of the SGSII cannot be used as a basis for an SGS rom?

They are totally different phones. different modems, cpu, screen, memory, size, chips, basically every way phones can be different. No way a transfer of a ROM between the two would work.

There is a 2.3.3 ROM that has some of the apps and features of the SGSII called SimplyGalaxyII i think, look in the dev section. THat is the closest we will get.

Yep - http://forum.xda-developers.com/showthread.php?t=1076724 This as about as close as you will get for now.

Thank you.
I was hoping that there was some way based on the sources shared (by Samsung) that a kernel could be built for the Cappy. But it looks like there too many differences to be able to take advantage of the fixes that they've put in.

Do you use the same drivers on your computer for all ati cards just because their built by Ati?

Actually yes. ATI calls their driver package catalyst you and download the same one no matter what ati card you are using.

Drivers are written with various choices in mind (I've written/modified a few myself).
Sometimes vendors create a family of "devices" that can be handled by the same driver. This is either controlled by compile time switches or even run time detection.
At other times, the vendor may develop a brand new hw architecture on a new device, and it may not be worth it to plumb an existing driver with code that runs across multiple device families.
Driver binaries will require device, target CPU arch and kernel APIs to be very close/exact match to be used across systems. Post #2 clarifies that this is not the case.
I did not have knowledge of the devices on the SGS II, and hence the OP: if they differ a lot.

So is the SGSII the next big development platform? That's what I'm hoping, as I'll probably get one come August, assuming they are out.

Just for arguments sake, lets say by some miracle we could get an sgs 2 rom on a cappy. How would it run? It would be expecting a dual core 1.2 ghz not a single 1 ghz, and double the ram. I doubt it would run at all.

Yes, the hardware is so different that ROMs designed for the GS2 will NEVER work on the GS1. Doesn't mean little parts here and there (like TW4 for example) can't be ported from one to the other, but as far as how the ROMs work at the driver level, it isn't possible to port the entire OS base.

Touchwiz 4 has already been ported and it runs fine, that's all you're going to get from that rom.

AndroidBooster (for devs)

I decided to share this with the community because I haven't seen this mentioned once anywhere.
To sum it up:
The main principle of AndroidBooster is to compile and execute embedded Java code (applications, services) as binary. Java code is executed faster and uses less CPU cycles. This saves battery life while boosting performance. Compatible with all Android platforms, AndroidBooster can increase performance by 10x compared to Dalvik Interpreter or 3x compared to Dalvik JIT.
You need an evaluation license to get your hands on this. More info at www.flexycore.com

if androidbooster is true to its words, i think its possible

--deleted--

any dev know how effective this would be?

I remember reading that most ARM11 and Cortex CPUs supports Java extensions, so there should be a boost.
By the way, look here to see test results for your device.
Edit: Just ran CaffeineMark (from Market) on my device (LG Optimus One P500 with heavily tweaked CyanogenMod 7) and compared it to the test results over FlexyCore.com:
Me: 1888
FlexyCore database entry for Gingerbread: 2726
Both benchmarks were made on 600MHz. I re-ran the test with my device overclocked to 748MHz and the test result was 2436.
So - AndroidBooster does work.

now we just need to know if any dev is willing to implement this into a rom. it would be great to see a significant boost in any rom

None of our developers can implement it as it is a closed source project. They (FlexyCore) offer to modify any ROM we send them, but they do not give out the code itself. They wouldn't earn money otherwise

[Q] Does Skype v2.1 Video work on the G2x?

I saw Skype updated to 2.1 today. My G2x is getting repaired so I can't try it, but has anyone been able to confirm if video works on this version?

No, It doesn't work. They have made it work with the Sensation and other phones release way after our G2X and the G2X is still not supported. What the hell? I am pissed as hell, I want to use it tooo...

That's really annoying. Skype is really the only reason I care about having a front-facing camera.

I tried Oovoo a short while ago, and had trouble with sideways video or sometimes no video at all. Guess I'll be trying again. And Skype should at the very least quit advertising that this works on practically all froyo+ devices... They need G2x support, and they need it soon. Taking their time has already earned them the low rating they have (or had before this release, fixing for many people) in the market.

The sensation's hummingbird does actually have Neon. Google sensation, hummingbird, neon, and you should see it. I always worry about posting links to outside of the forum, but it's easy to see.
They do claim it'll only work on 2.2+ devices with neon capabilities... I'm no electrical engineer or dev so I have no idea why both gtalk video and skype need it but they do.
Sadly it means it's not as easy as a build.prop fix. One day... or I'll just get a phone with tegra 3 when that comes along which has neon support haha.

Hmm, interesting. I remember reading somewhere on XDA that "Our friends over at the Sensation board are out of luck as well as the Snapdragon doesn't have NEON either."
Oops, sorry, I meant Snapdragon. Haha XD
I wonder if that guy is still right, though. If he is wrong, that explains why Sensation is officially supported while non-NEON t2 is not. But... If he's right, there is no reason why Skype doesn't support t2 and in that case a build.prop change or decompile and removal of the apk's device checks would work.
Got some looking up to do...

I'm pretty sure Snapdragon doesn't have NEON. Qualcomm licensed the ARMv7 ISA only and not the Cortex-A8 or A9 designs(The Cortex-A8 introduced the NEON core FPU but you seem to know this). The ARMv7 ISA only mandates Thumb and such.

From personal experience of doing video encode from an Android device;FFmpeg, the open source library for video encode/decode is preferred on Android and is very optimized for NEON(TI is one of the main contributors for FFmpeg for ARM and all TI OMAP3 and OMAP4 designs have NEON). I'm guessing the video APIs for Android use FFmpeg so Gtalk and Skype would be reliant on these libraries.
However the Atrix got Gtalk so there probably is some workaround for this...

Ahh, OK, thanks for the clarification. So Skype has adapted an official certified version for non-NEON processors, meaning there shouldn't be much reason why they still aren't supporting Tegra 2.

That is correct, both apps rely on NEON and that's why previous ports failed. Atrix (T2) did get gtalk, so there is a new attempt underway. Have a look at http://forum.xda-developers.com/showthread.php?t=1184999
There hasn't been too much progress (at least publicly displayed) or as much as the LG cam port attempt, but it's promising. And now that a version of Skype is availible for a non-neon processor, I'm guessing our wonderful devs will soon attempt to use the new libraries to make a working port. Let's hope for the best

CM 97 has some FFC/cam fixes(looked at changelog) so it might.

That's some BS. The G2X has been out 2 months longer then the Sensation! -__-

let me see if i understand this correctly

so the g2x has a duel core processer that gingerbread does not support? so i'm only useing one. and ics does support duel cores. the only way i'll get ics is to root my phone and wait for on of the devs to get an ics rom working on the the g2x. thanks in advance

In a nutshell

It controls the two CPUs as one, it doesn't just use one. The rest I believe is correct.

I think even rooting the phone and waiting for ICS from here will still not use the dual core properly as it will not have the Nvidia drivers till after it is released by LG.

WOW, thats pretty weak.

It's not that you're only using one core, it's that the two cores cannot function independently. They both focus on the same task and clock at the same speed, all the time. So you do notice an increase in performance above, say, a Nexus S, but it's not as good as it could be.
This is not a limitation of Gingerbread per say, but more a limitation of the drivers. Since nVidia does not release their driver source, we have to wait for them to provide better ones, which in all likelihood will never happen.

Two processors, one task
Due to resource sharing (cache, memory, mass storage, I/O), it is VERY hard to get two processors to work on one task. Some manager/executive would have to partition or parallelize the work between the two processors. And most tasks have many serial operations - what mechanism is going to serialize the tasks amongst two processors? I have yet to see a linux kernel expert on these forums declare Froyo or GB his a linux kernel that supports this.
The procs have dedicated L1 cache, and a shared L2 cache - stale cache blocks (aka cache miss) would be a nightmare if two procs were working on the same task - it would actually be slower.
Symmetric multi-core is made for multiple tasks or threads, not trying to parallelize a single task. I thought this was discussed in another thread...

thanks for the forward
edit:so i was reading the forwarded link and i ran in another like
http://api.viglink.com/api/click?fo...alcore-1015/&jsonp=vglnk_jsonp_13219228920753
and in this link it says the tegra 2 didn't use the asynchronous duel cores because nividia says it loses 10-15% performance. so i'm led to believe there not working independently. unless i'm misunderstanding.

Both cores are running just not as efficiently as they could with multi-threading. ICS will multi-thread and properly use the dual cores.

Thread scheduler
So does anyone know what mechanism handles thread scheduling? I guess it'd have to be at the Android layer... And I thought that was introduced in 3.0?

tegra 2 harmony video excelerated kernel

I was just wondering, the viewsonic gtablet is a tegra 2 harmony device and the guys at team drh have made a kernel for ics that is fully hardware excelerated so my question is since the g2x is a harmony device can the drh kernel be used as a base for a working g2x kernel with full video decoding just like the gtablet???

Harmony is for tablets. We have Ventana.
Closest best is the ZTE Mimosa X which has ICS and the Ventana. When it drops hopefully we can grab the drivers from there.

From the 2x side:
msedek said:
If porting full working drivers were possible in any way from any device to make o2x runs with everything working on ics it should be done by now.. Al the things you are thinking now developers though about it long time ago... I'm developer myself.. Just not android developer.. I develop in assembler for microcontrollers as I am electronics engineer, and trust me there's nothing that I don't know about the chips I work on...
Every microcontroler (I'm specialist in microchip) has different libraries to access the different modules... As microchip produce open source libraries I can access all the functionalities in the processor and microchip provide the full pdf with the instructions set for every processor.. But even chips from the same family with a minimum variation like let's say pic18f478 to pic18f478a can have bunch of different modules with a bunch of different libraries...
So once I can develop a function out of the instructions set (what's called here from scratch) I can then develop a library wich I can call in my main software every time I want the processor execute an action... So in this case Nvidia won't provide their instructions set for their processors... They only provide libraries to oems... And oems can develop procedures and functions with these libraries...
That said Nvidia has no responsibilities here... Because no matter what os oems use the chips and the libraries are the same and the method to access chipset function won't change from one os to another... That's processor architecture and can not be modified..
LG has to re develop the function and procedures to work with the new os that is low level (assembler compiled) and embedded into the os... Those functions are way different from one device to another and it's not possible to use them unless it's the same exact chip family with no variants...
Devs here can not develop functions because they don't have access to the libraries... They only have access to the final product or what I could call the UI for developer.. And that's the DRIVERS..
That's it..
