The s390x diagnose 318 instruction sets the control program name code (CPNC) and control program version code (CPVC) to provide useful information regarding the OS during debugging. The CPNC is explicitly set to 4 to indicate a Linux/KVM environment. The CPVC is a 7-byte value containing: - 3-byte Linux version code, currently set to 0 - 3-byte unique value, currently set to 0 - 1-byte trailing null Signed-off-by: Collin Walling <walling@linux.ibm.com> Acked-by: Janosch Frank <frankja@linux.ibm.com> Acked-by: Heiko Carstens <heiko.carstens@de.ibm.com> Reviewed-by: David Hildenbrand <david@redhat.com> Reviewed-by: Cornelia Huck <cohuck@redhat.com> Message-Id: <1544135405-22385-2-git-send-email-walling@linux.ibm.com> [set version code to 0 until the structure is fully defined] Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
