QEMU on IGEP Boards
QEMU is a processor emulator that relies on dynamic binary translation to achieve a reasonable speed while being easy to port on new host CPU architectures.
In conjunction with CPU emulation, it also provides a set of device models, allowing it to run a variety of unmodified guest operating systems; it can thus be viewed as a hosted virtual machine monitor. It also provides an accelerated mode for supporting a mixture of binary translation (for kernel code) and native execution (for user code), in the same fashion as VMware Workstation and VirtualBox. QEMU can also be used purely for CPU emulation for user level processes, allowing applications compiled for one architecture to be run on another.
Build QEMU with IGEP support
Download QEMU sources from linaro git repository:
$ git clone git://git.linaro.org/qemu/qemu-linaro.git
Download IGEP support patch for QEMU from this link and after that apply the patch as:
$ cd qemu-linaro
$ patch -p1 < 0001-IGEP_QEMU_support.path
Configure the sources for build with this command:
$ ./configure --target-list=arm-softmmu --prefix=/opt/qemu-linaro
Build the sources:
$ make
Install QEMU:
$ make install
Optionally you can download from here the QEMU binaries.
Board Emulation
