zpcictl is used to manage PCI devices on z Systems. In this first
version it is mainly used to handle erroneous PCI devices by changing
their state and make those changes known to the SE. Log data, such as
S.M.A.R.T. data for NVMe devices, is sent alongside those state changes.
The state change is issued by sending data via the PCI 'report_error'
sysfs attribute. It's a binary attribute which will cause the host to
send an Adapter Notification Event.

This patch prevents code duplication in vmcp related programs.
Some applications such as vmur, vmcp, and lsqeth
use z/VM CP commands to query information. Each program
uses its own defines and code.
Supply a library and common header file to use common code.

If SYSTEMDSYSTEMUNITDIR is defined, the systemd units are automatically
installed. Therefore consequently also install the required config files
in that case.
Example:
$ make install SYSTEMDSYSTEMUNITDIR=/usr/lib/systemd/system/

A set of scripts and a short documentation describing how to build
a network boot image simulating a PXELINUX-style boot process.
Starting with QEMU 2.10 it is possible to boot a KVM guest over a
network interface using DHCP/BOOTP. The boot process is triggered by
the network boot firmware that is part of QEMU and follows the usual
network boot pattern: a DHCP request is issued by the client and
answered by a DHCP/BOOTP server. The DHCP reply will contain a
TFPT server identification and a bootfile name. The client will
retrieve the bootfile from the TFTP server, load it into memory
and IPL it.
A very common way of setting up a boot server has been defined
by PXELINUX, an open source implementation of PXE. With PXELINUX
the bootfile is a small network boot loader that will retrieve
a potentially client-specific configuration file containing
further instructions for the final boot process (kernel, ramdisk,...).
The set of sample scripts contained in the netboot directory provide
directions for a Linux distributor or a boot server administrator
on how to build a network boot image usable for a simplified
PXELINUX-style network boot setup for s390.
Note that the sample scripts are implementing only a subset of PXELINUX
functionality, specifically the config file parsing. In order to
get full functionality, a more specialized boot loader program
like petitboot or pxe-kexec must be used in the ramdisk.
Further, a sample Dockerfile is provided along with instructions on how
to build the network boot image in a Docker container.
