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
Solution
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
