IOMMU Emulation and install with QEMU

Question

For now, I need to use some packages to do a emulation for IOMMU (it is similar to MMU), and I got some source about it, but I don't know how to use them.

http://www.spinics.net/lists/kvm/msg38514.html Here is a link of source for emulating IOMMU

http://repo.or.cz/w/qemu-kvm/amd-iommu.git Here is a link for downloading file for this emulation

My problem is how to use qemu to do this and there are so many file in the download list, I don't know how to use them...

Thanks for your help, really appreciate!!! If you know something detail, please tell me

Answer 1

you can use download option in the right side of the page ( Generally snapshot option is available in repositories ) or this

then simply use configure script to generate makefile
i.e.

use ccache if you want to recompile it again and again

$CC="ccache gcc"./configure --prefix=$PREFIX <br>

then make to build and install, use -j<no_of_cpu+1>

$make -j5 all install

if you have dependencies issue, solve them using synaptic manager or apt-get

P.S. AFAIK You should have iommu support available in hardware, if you have 64-bit machine then you might have. You can check flags in using cat /proc/cpuinfo
