memory, after expansion this
includes the expansion area
length
0004 4 Signed 4 ARDHXL Expanded section length as
created by CP on the singleton
member. Used when the ARD is
expanded on other members who
might be running an older version
of CP. On the originating system
ARDHXL will equal ARDHXLEN.
0008 8 Signed 4 ARDHVER Version of ARD Encoding Structure
BEGIN NEW SECTION CAUTION ARDHVER
reflects the version of CP that
built the PDR ARD. It is checked
for compatibility with the
executing CP by comparing it with
ARDHCPV. Members whose singleton
ARDs have differing versions
cannot co-exist in the same
domain. Check for compatibility
must be done before calling
HCPARDUA, HCPARDIA, HCPARDXP and
HCPARDDP
The version is changed only when an extension to the ARD structure
mandates a concomitant compatibility APAR for routines that
manipulate ARDs. Some extensions to the ARD can be tolerated by a
version of CP that was built using older ARD DSECTS. In general
extensions that don't mandate a version change are:
Extensions to the host STFLE String
Extensions to the SIE STFLE Strings
Extensions to the CP Architecture Section - Masks and additional
architectures
Extensions to the FII sections
Extension to other sections will need careful consideration.
Extensions to the vector table will mandate a change in ARD
version.
Equates for absolute version numbers of the ARD used to
identify specific versions of the ARD.

0000 0 Structure ARDCASEC ARCHITECTURE DESCRIPTION BLOCK
CP Supported Architectures Section.
This comprises a self-describing table of STFLE Masks
which are ANDed against the native STFLE string to determine
the feature set of each supported architecture (currently:
zArchitecture, ESA/390, XC/390, zAchitecture-only, z/XC).
The table is preceded by a byte number of entries
Each entry comprises a byte indicating architecture,
a byte count of number of mask half words that follow.
The masks for each architecture are coded as equates to be
used when building the ARDBK.
The number of mask bytes stored per architecture is a multiple of
halfwords, not necessarily equal to the number of STFLE doublewords
but sufficient for masking purposes.
See HCPARD for more details on how the guest STFLE responses
are created.
Important considerations when updating this section:
HCPARD assumes that future updates to this section are cumulative.
The overall length of this section is used to determine whether one
ARD is a superset of another. Updates, which may include adding
support for a new architecture and extensions to the STFLE masks
must be well ordered.

The following equates represent the architecture supported by
this version of CP.
To increase the number of supported architectures and facilities
Set ARDCAARS and define the STFLE masks accordingly. Code in
HCPARD does have tolerance for more than three guest architectures
being present in the ARD but does not support the removal of an
obsolete architecture or the re-ordering of architectures in the
ARDCAARC table.

0000 0 Structure ARDSTSEC ARCHITECTURE DESCRIPTION BLOCK
This section is initially populated by the host STFLE string of
the singleton member ARD. Following the formation of domains of more
than one member this represents the common subset of native features
present for all members of the domain. Nevertheless it is still
referred to as the native STFLE string in HCPARD.
For the singleton ARD the space reserved will be precisely the
length of the host STFLE string stored on that member. There is no
overflow space reserved as was formerly done by HCPBIE because:
the ARD is rebuilt following an architecture upgrade.
the SIE Interpreted STFLE responses are in ARDSISEC. These do
contain expansion room for the same reasons as was done in HCPBIE.
Where there are multiple members comprising a domain the space
reserved will be the maximum of all the singleton native STFLE
strings. No matter what domain the ARD represents, the length of
the native STFLE string may be obtained from ARDHNSLN or ARDVSTFL

HCPARDBA on the member they represent.
All sections following are built on expansion by HCPARDXP by all
members of the SSI. Sections of fixed-length are inserted before

This section is modelled on the VSIM data that was used formerly to
record STFLE data for all guests.
ARDCANAR is used to determine the number of array entries
(ARDCAARS is used only to build the ARD by the local member)
Notes : throughout the ARD STFLE related arrays are always store
in ascending order of ARDCAATP (architecture type). This
simplifies search algorithms and must be adhered to.
0000 0 Signed 4 ARDNFLL (0) Array of host logical addresses
of guest STFLE responses
0000 0 Signed 4 ARDNFLZL Host logical address of STFLE
response for z/Arch guest
(non-XC)

response for 390 guest (non-XC)
0008 8 Signed 4 ARDNFLXL Host logical address of STFLE
response for XC guest

They are necessarily equal length entries equal to the size
of the native string plus one double-word for reasons of
overflow caused by concurrent firmware update.
