[Qemu-devel] Can we run code for ARM920T core (at91rm9200) in qemu

[vibisreenivasan]

Hello,
	Can we run code compiled for at91rm9200 (uses arm920T core) in 
	latest version of qemu.
	
	Is there any support for ARM7TDMI core.?

Thanks & Regards

Maybe in userland emulation, but there's no at91rm9200 emulation right
now.

The ARM userspace instruction set seems to work well.

hi Warner,
	Thanks for the fast response.
	Is there any one working on adding support for ARM920T core.
	
	Can any one give me some points on how to add support for
	ARM920T core.
	
	thanks & regards

Most (all?) of the instructions ARM920T supports are in ARM926 too so
most of the changes would be restricting the exisitng instruction set
to generate faults on v5-only instructions.  If you don't care about
the faults then mostly anything that runs on ARM920T will run in qemu
as is.  The openmoko qemu tree emulates a cpu with an ARM920T core but
without implementing the differences from arm926.

Cheers

Thanks for the reply..
Any Idea about qemu support for ARM7TDMI core?Any one planning to
implement that?
