Hi,

Does Linux kernel for MIPS assumes that its link address is always in Kseg0?
What if I change the link address to somewhere in useg?

Your page fault handlers will be in for an interesting time. ;o)

What you describe can be, and is done, for virtualized kernels running on top of a hypervisor, but there's a bit more involved than just changing the link address.
Hi Kevin,

You just caught that. Thats what I am trying to evaluate. What all I would need to do apart from changing the link address. I am working on a bare metal hypervisor for MIPS architecture.

Any pointers?

Himanshu
