+  * SCLP event type 11 - Control-Program Identification (CPI):
+  *    CPI is used to send program identifiers from the guest to the
+  *    Service-Call Logical Processor (SCLP). It is not sent by the SCLP.
+  *
+  *    Control-program identifiers provide data about the guest operating
+  *    system.  The control-program identifiers are: system type, system name,
+  *    system level and sysplex name.
+  *
+  *    In Linux, all the control-program identifiers are user configurable. The
+  *    system type, system name, and sysplex name use EBCDIC characters from
+  *    this set: capital A-Z, 0-9, $, @, #, and blank.  In Linux, the system
+  *    type, system name and sysplex name are arbitrary free-form texts.
+  *
+  *    In Linux, the 8-byte hexadecimal system-level has the format
+  *    0x<a><b><cc><dd><eeee><ff><gg><hh>, where:
+  *    <a>: is a 4-bit digit, its most significant bit indicates hypervisor use
+  *    <b>: is one digit that represents Linux distributions as follows
+  *    0: generic Linux
+  *    1: Red Hat Enterprise Linux
+  *    2: SUSE Linux Enterprise Server
+  *    3: Canonical Ubuntu
+  *    4: Fedora
+  *    5: openSUSE Leap
+  *    6: Debian GNU/Linux
+  *    7: Red Hat Enterprise Linux CoreOS
+  *    <cc>: are two digits for a distribution-specific encoding of the major
+  *    version of the distribution
+  *    <dd>: are two digits for a distribution-specific encoding of the minor
+  *    version of the distribution
+  *    <eeee>: are four digits for the patch level of the distribution
+  *    <ff>: are two digits for the major version of the kernel
+  *    <gg>: are two digits for the minor version of the kernel
+  *    <hh>: are two digits for the stable version of the kernel
+  *    (e.g. 74872343805430528, when converted to hex is 0x010a000000060b00). On
+  *    machines prior to z16, some of the values are not available to display.
+  *
+  *    Sysplex refers to a cluster of logical partitions that communicates and
+  *    co-operates with each other.
+  *
+  *    The CPI feature is supported since 10.1.
