Building a kernel with the S/390 hypervisor file system

6.10 LPAR mode z/VM guest

There is an option in the kernel configuration menu that you must select to compile a kernel with the S/390® hypervisor file system.

Kernel builders: This information is intended for those who want to build their own kernel. Be aware that both compiling your own kernel or recompiling an existing distribution usually means that you have to maintain your kernel yourself.

You must select the kernel configuration option CONFIG_S390_HYPFS_FS to be able to access LPAR CPU data.
