Re: porting reversible on arm/mips

[paawan oza <paawan1982@yahoo.com>]

Hi Hui and Michael,

I have been trying to setup qemu, on suse10 sp1/2 host... I did not get correct source till now.
I got some binaries for suse10.2.    (kqemu.ko was not compatible)
And also arm kernel images, I did not get the one.
setting up qemu on 2.6.16 suse10.2 with arm kernel seems to be not so friendly.
if any pointer links, will be helpful to me.

another option what Micahel suggested...
"There's a nice separation in prec between architecture and OS/ABI.  You could begin with the arm simulator that comes
built-in to gdb, and do the architecture part before tackling the Linux ABI part."
above also seems to be good too. for the time being I just concentrate on arch part and forget Linux ABI for the time being..

please provide your inputs.

Regards,
Oza.

Hi All,

In conclusion we have following approaches to go ahead with.

1) have qemu or skyeye on windows and get the arm kernel on to it.

2) Using arm-elf-gdb, and use 'target simulator' command, and cross compiling test programs for arm.

1st gives me complete environment.
2nd may be a part of it.

any thing is ok as long as that gives smooth start.
I will try to setup qemu first and see.

Thanks for your help.
Regards,
Oza.

If you configure gdb as "arm-elf", gdb will build with
its own linked-in arm simulator which you can use by
means of the gdb command "target simulator".

That is correct.   You can build arm-elf-gdb on x86 host.
You will probably want to build arm-elf-gcc and asm and linker,
so that you can compile test programs to simulate.
