Porting Andorid for MIPS

[manjunatha srinivasan]

Hi
What are major changes has to come in while porting android for MIPS platform(sigma design board)?

Hi David Turner
Thanks for reply .

From link below i found the basic idea of porting C library for
MIPS. My doubt is any android specific change required in porting, or
is it a basic porting steps followed in every new processor
architecture. Please clarify.

What are the steps involved of porting of bionic and dalvik for MIPS?
Please provide any sample link of x86 arch porting as cross reference.

Porting the C library to a new CPU architecture requires at the very minimum the following:

- modify SYSCALLS.TXT to include the MIPS-specific Linux kernel syscalls
- modify bionic/libc/tools/gensyscalls.py to add MIPS-specific assembly fragments for the syscall stub generator
- probably modify bionic/libc/tools/checksyscalls.py to support MIPS as well
- a set of Linux kernel that should be placed into bionic/libc/kernel/original. *Please* read the docs in bionic/libc/kernel/ to understand what this means
- modify bionic/libc/kernel-tools/default.py to support MIPS as well
- re-generate cleaned-up kernel headers through bionic/libc/kernel/tools/update-all.py
- re-generate MIPS-specific syscall stubs through your updated gensyscalls.py script
- provide MIPS-specific assembly sources for a few things, like the ones on bionic/libc/arch-arm/. Most of these can be taken from recent OpenBSD sources
- testing, testing, testing...

I advise you to send patches for review on Gerrit so we can see what you're trying to do and tell you if it's ok, etc..

Before porting MIPS based bionic C library for Android, i believe that
MIPS cross binutils, MIPS cross gcc are to be set ready for
compilation. If so, Is cross-gcc (4.2.1), cross-binutils(2.17) are to
be compiled from source code and what is the compilation procedure and
where to place in directory structure?
