This is an extension of the already existing hypfs for LPAR (DIAG 204). Data returned by DIAG 2fc is exported using the s390_hypfs when Linux is running under z/VM. Information about cpus and memory is provided. Data is put into different virtual files which can be accessed from user space. All values are represented as ASCII strings Signed-off-by: Michael Holzheu <holzheu@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
