[Dev] [Tizen Product-dev] Tizen on MIPS arch

I found the toolchain repos in "ssh review.tizen.org gerrit ls-projects | grep toolchains 2>&1 | tee toolchain.lst" . 
I have attached the list. What are steps to create RPMs for MIPS arch?

Hi, I have tried to pack the Mentrographics(CodeSourcery) MIPS tool chain to RPMs and place in pre-built/toolchain-mips folder. 
But there are lot of packages which are not there in Mentor tool chain. 

How to get the tool chain for MIPS. Are there any tool chain sources repos, from which I can build cross platform toolchain for MIPS? 
If yes, how to build them?

Murthy NSSR.

Great! 
Feel fre to notify me if any changes needed in them. 


Whould be great if you can answer this also: 
Also, take a look into patch for qemu at the end of the page here http://patchwork.ozlabs.org/patch/250161/ . It hould be aplied if you want qemu to work properly for mipsel. 


One more question about qemu, we have fixed mask for qemu-reg( /usr/lib/build/qemu-reg from build package ) for mipsel platform and don't know where to submit it. Whould be great if anyone can help us with that. 


Don't we need any changes to scm/meta/build-config/build. conf file like "Optflags" for architecture specific compiler options? 


Not shure, we have a lot of things changed because of platform specifics, but can't find anything mips related 

And I see there are many "%ifarch %{arm}" in spec files of various packages? Do we need to do something here to be MIPS specific? 



Most of our changes in .specs where specific to our platform. But you would need to look into patch http://patchwork.ozlabs.org/patch/250161/ and fix qemu-reg(we will contribute fix as soon as we know where to contribute)

Sorry for noticing these patches of building tools so late, because we were rotating the maintainers those days. We are going to verify and integrate them ASAP for the convenience of MIPS porting. 



thanks

Hi all! It looks like we already tried to push our changes in Jul? but they wasn't reviewed. Whould be great if they we'll be reviewed sooner this time.

ok then I guess you want to build this profile : 

https://build.tizen.org/project/show?project=Tizen%3A2.3%3AWearable 

Make sure you have every sources because IICR there are binary blobs (ARMv7l) 
in this profile

None I know at least

Sorry I don't know any, may others in this list give you better hints 
I can only help you to have MIPS support for Tizen:Common 
in hope it will be available for downstream profiles (ie: IVI at the moment) 

Good luck
