[Qemu-devel] How to map a small portion of address space to DCache in QEMU?

[Muhammad Nouman]

Hi! There is a special segment in Octeon processors (CVMSEG)

which maps a small portion of MIPS64 address space to

Data Cache. This region is used by the user applications

as scratch space and this space is saved by Octeon Kernel

on context switches.

How can we do this mapping (i.e. some part of Mem to

DCache) in QEMU?  Is there any such example code in

QEMU?

Thanks
