[DISCUSSION][Q&A] Broadcom SOC hardware and driver related infos - General Topics

Hello everyone ! So I opened this thread to talk and get some clarifications on some of Broadcom SoCs. People with knowledge are wellcome to share some light !
Let's get started ,today the culprit is Broadcom Bcm2157 SoC . Tried to find detailed hardwer informations ,but I only managed to find that this bad boy it is a dual core 500mhz armv6. No infos about gpu or memory interface. So I looked deeper but i found nothing. Then i found about BCM21553 , armv6 with a supposed VideoCore IV Gpu. Could be possible bcm2157 to have the same GPU? If yes , how easy would be to port the android gpu drivers from 21553 source code to 2157?

Found my answer ..... really dissapointed !

samsung vs qualcomm ?

Hi, i wanted to ask which processor is faster:
The 400mhz Samsung of the Tytn or the 400mhz Qualcomm of the Tytn II ?
What are the advantages of each processor?
I heard that the samsung has a better connection to the flash, but i couldn't find much information in the web. Thx!
i would like to know that too.....
me too...
but i think the advantage (only of the chipset, not the devices with the chip!) of qualcomm are the all-in-one-chip-technology..
its all in one chip.. the gpu, fm-radio, gps, and so on....
According to Adama over at Brihthand, the Samaung chip is slightly faster than the MSM7200 and exactly the same speed as the MSM7500. Not sure where he gets his megaflop test data.

... and, currently, the lack of proper driver support....
however, I'd still go with the Qualcomm.

[Q] [ASK]armv7

Hi all, I have read many articles that say to be able to use adobe flash player 10.1 you must have armv7 processor, I was wondering,
what's the difference between armv6 and armv7?
Is it possible to modify the armv6 based phone to be able to use that?
wht r phones that use armv7?
thx b4..
Hi and welcome
You can not change the processor, it would be like making your P4 a core i5, I think the difference is in the architecture and the instructions.
However you can check if your phone supports it or not, devices with qualcomm snapdragon should support flash, you can find a comprehensive list of device specs here - pdadb.net

i see, so just the phone with qualcomm snapdragon that will support flash right?
is there any chance the other phone with different processor could do the same?
Because if not, it will affect the price of all entry level android phone in the future and it means we have to buy an expensive android phone to just be able to use flash
The samsungs with the ~1 Ghz CPU will probably support it, as well as tegra and tiomap, just check the particular device you want

Huawei U8150: dual core ?

U8150's CPU, MSM7225, seems having dual core:
from qualcomm web site (as a new member I am not allowed posting link directly)
news/releases/2007/02/12/qualcomm-enables-mass-market-smartphones-wireless-market
Does any kernel support this feature?
This phone is powerfull and has more "things" than we can think it has.. but dualcore?.. i dont know really because im a new user in this too and i don't know a lot of it...
It would be great to have a dualcore gadget, heh.
This is interesting - I note that it's a "dual-PROCESSOR architecture" - not a dual-core. Is this already being used by android? Supposedly there's a GPU hidden in there too. (perhaps this is what they're referring to?)
It's Single Core....
It is single core. The news release was kind of misleading. Dual processor was referencing one for apps and the other for modem.
There seems to be no gpu in msm7225, though there is one in msm7227.

[Q] Combines SGS III Mali Drivers from Kernel with RK3188 Kernel

Howdy all,
I am a bit new around here but I stay pretty busy on some other forums and I run a site called rockchipfirmare.com. I don't consider myself a developer in the true sense of the word but rather I mix-n-mash roms primarily without getting into too much actual coding.
So I have a question that is slightly out of my league and I am hoping someone with a bit more knowledge can lend a hand.
I have two chipsets in front of me.
One is the Samsung Exynost 4412 (Quad-Core A9 with Mali-400 MP4 gpu)
The other is a Rockchip RK3188 (Quad-Core A9 with Mali-400 MP4 gpu)
Basically, I have noticed that Exynos pretty much runs EVERYTHING just a little bit smoother than the RK3188 does, even though the RK3188 actually does better in most synthetic benchmarks.
I think it -might- be a driver optimization issue as I am sure Samsung does a heck of a lot more with their drivers than Rockhip. I also suspect that the Mali-400 GPU in the RK3188 is running at a lower clock than Rockchip claims. Thus far I haven't found a way to figure out what the GPU specifically is clocked at.
Anyhow, here is my question....
Would it be possible to get the Samsung Mali drivers from the Siyah kernel and import them into the RK3188 kernal for a specific device?
I think I have most of the tools to do so already as I can unpack and repack boot images for the RK3188. Although I never have gotten into the extracted kernel image.
I guess I am asking if I should spend time on the above or whether it is a fools errand and if I do spend time on it what exactly am I looking to get from the SIyah kernel once I get into it?
Any thoughts our help someone would like to throw my way are most welcome.
Kind Regards,
Roman
Would be wonderful if someone can do this
Well, that is what I am try to learn, how to combine different modules drivers.
If the module is compile with the same kernel version (Linux 3.0.36), then maybe it could work.
How is going so far? I really would like to learn about that to be able to recollect all the modules for different RK3188 tablets and the be able to recompile new version of the kernel.
I am going to start playing with a PIPO M6 but any help will be much appreciated.
Note: If the GPU driver are integrated in the kernel I don't know you are going to be able to use them, as you cannot build a complete kernel for your RK8188 tablet.
For mali, the source code is open source and it can be found at http://malideveloper.arm.com/develo...source-mali-gpus-linux-kernel-device-drivers/

Can I run ARMV7 or higher apps on Mediatek MT6592

I can't figure it out. I have an old phone which can run apps meant for ARMv6 processor but the apps made for ARMv7 or higher processor force close on my device. This means that my device has ARMv6 compatible processor.
Now I'm planning to buy a new phone & found one to my expectation. That phone has Mediatek MT6592 processor.
So I want to know whether I will be able to use apps which are compatible with ARMv7 or higher processor on the new phone with Mediatek MT6592 processor?
Please help me...!!!
Oh Yes!! I got it...
& thanks for giving no ideas
