1. In principle you have to follow the tutorial above. After the configuration (step 2 in the above tutorial) go to the subdirectory `linux`, which contains the source code of the Linux kernel. Configure the kernel with `make menuconfig` for your system. Be sure, that the option `CONFIG_HERMIT_CORE` in `Processor type and features` is enabled.
|
||||
2. Go back to the root directory of this repository and build with `make` the Linux kernel, the HermitCore kernel, the cross-compiler and the demo applications.
|
||||
3. Install the Linux kernel and its initial ramdisk on your system (see descriptions of your Linux distribution).
|
||||
3. Install the Linux kernel and its initial ramdisk on your system (see descriptions of your Linux distribution). We recommend to disable Linux NO_HZ feature by setting the kernel parameter `no_hz=off`. This feature reduces partly the OS noise, but noise sensitive applications should now run on HermitCore.
|
||||
4. Register the HermitCore loader to your system with following command: `echo ":hermit:M:7:\\x42:/path2proyxy/proxy:" > /proc/sys/fs/binfmt_misc/register`, in which `path2proxy` defines the path to the loader. You find the loader `proxy` after building the HermiCore sources in the subdirectory `hermit/tools` of the directory, which contains this *README*.
|
||||
5. The IP device between HermitCore and Linux does currently not support IPv6. Consequently, disable IPv6 by adding following line to `/etc/sysctl.conf`: `net.ipv6.conf.mmnif.disable_ipv6 = 1`.
|
||||
6. Per default, the IP device uses a static IP address range. Linux has to use `162.168.28.1`, where HermitCore isles start with `192.168.28.2` (isle 0). The network manager must be configured accordingly and consequently the file `/etc/sysconfig/network-scripts/ifcfg-mmnif` must be created with following contents:
