Function : A managed, in memory copy of STSI output. The following STSI responses are maintained: 1.1.1 and 1.2.2. For STSI 1.1.1 and 1.2.2, an additional pair of data areas is maintained that contains the most recent responses with non-transient states indicated. See SSI1TRNS and HCPSSICC. These are needed for Diagnose x'2E0'. References to these data areas during CP initialization must test the pointers to ensure they are initialized (nonzero pointer) before using the response areas. HCPSSIBK maps the STSI responses. Serialized : These data areas are updated only during system initialization while running on a single processor, or later while running on the SYSTEM VMDBK. Each time the STSI responses are updated, a new data area is allocated and the pointers below are updated. The prior response area is released by an MPDFR call to HCPSSIRL to allow existing references to continue to use the old response areas until their next loss of control. No serialization is provided to consumers of these data areas that allows access over a loss of control. The STSI response area may have been released during the loss of control. No form of serialization can provide a self-consistency guarantee for the pair of responses for STSI 1.1.1 and 1.2.2 since changes may occur between the STSI instruction invocations that affect values reported in both STSI responses. For example, changes to capability values reported by STSI 1.2.2 may be explained by corresponding changes to CCR and CAI values reported by STSI 1.1.1. 008C 140 Address 4 RCC111 Most recent STSI 1.1.1 response. 0090 144 Address 4 RCC122 Most recent STSI 1.2.2 response. 0094 148 Address 4 RCC111NT Non-transient STSI 1.1.1 resp. 0098 152 Address 4 RCC122NT Non-transient STSI 1.2.2 resp. RCCEMSxx: EMSBK Cleanup Counts and Type flags Function : Track statistics for cleanup of EMSBKs found on the PFXPG of a processor during VARY processing. The individual counts are for different points in the processing of VARY OFF PROC/CORE and VARY ON PROC/CORE. If the EMSBKs are cleaned up after the HCPMPCLF processing, then the EMSBKs may have been waiting to be processed for 2 minutes or more. This should be avoided because the result will be that the tasks waiting for completion of HCPSGP's processing will appear to hang while the EMSBK is on the PFXEMSAN queue. Currently, this is only the case for HCPSGPNC's callers indicated by RCCEMSNF.RCCEMSNC being on. There should be a count field and flag byte for each caller of HCPSGPDR.

STSI 15.1.x response data area & system topology fields Function : To save System Topology (STSI 15.1.x) data and counters related to how often the data has been updated. A lock is defined as these fields can only be updated when the lock is held exclusive and can only be read/copied when the lock is held shared. System Topology data is saved in storage for 1st level CP systems. Periodically, CP polls (via PTF FC 2) to determine if the system topology has changed. If it has, STSI 15.1.x is issued to update the System Topology data in storage. When monitor needs to cut a system topology configuration record (D1R26) or an event record (D5R14), the fields are copied while the lock is held shared to ensure the values are not being updated at the time. The lock is released before the copied data is passed to the monitor routine because monitor might lose control while processing the data. HCPSSIBK maps the STSI responses including the first part of the STSI 15.1.x response. Serialized : The following data areas are serialized by the Topology lock (HCPDSVTL). This lock must be held as follows to ensure these fields are kept in sync and apply to the same instance of system topology (STSI 15.1.x) response: EXCLUSIVE: * Whenever any of the fields are changed. * For STSI data updates, the lock must be held from BEFORE the PTF FC 2 until after the STSI 15.1.x is issued to ensure the saved STSI data is the most current. SHARED: * Whenever 2 or more fields are read/copied and need to be in sync with each other. This lock is *NOT* to be held over a loss of control. 00B0 176 Dbl-Word 8 * (3) Reserved for IBM use 00C8 200 Bitstring 1 RCCTOPFG Flags for STSI 15.1.x information 1... ....

Serialized : These fields are serialized by the Vary Processor Lock (HCPRCCVA) and the Topology Lock (HCPDSVTL), unless otherwise noted. 00D8 216 Signed 4 RCCDEDCT Count of Dedicated vCPUs. Serialized by vary proc lock 00DC 220 Signed 4 RCCDSVCH Count of times DSVBK association has been changed. In addition to when Topology changes are detected, CPU dedication changes can also cause us to change DSVBK association. 00E0 224 Dbl-Word 8 * (0) 00E0 224 Signed 8 RCCDSVTM TOD value at last DSVBK assoc change. 00E8 232 Bitstring 64 RCCVALID Mask of CPUs that have valid association to DSVBKs. 0128 296 Address 4 RCCTOPBF Address of pre-allocated buffer from which to "allocate" TOPBKs 012C 300 Signed 4 RCCTOPBS Length in bytes of the RCCTOPBF buffer 0130 304 Address 4 RCCTOPCU Cursor/pointer into the RCCTOPBF buffer from where the next TOPBK should be allocated. Miscellaneous data fields RCCPROC and RCCCORE are dynamically allocated limits and should be used solely for any dynamically allocated structures. For compile time structures refer to HCPEQUAT for associated allocation limits. 0134 308 Signed 2 RCCPROC MIN of z/VM supported limit on maximum number of LCPUs and partition supported limit on maximum number of cores times the max threading level. Used to allocate PFXPG table array and SXLBK related arrays. This is a limit on the number of CPUs AND the maximum allowed CPU address. 0136 310 Signed 2 RCCCORE MIN of z/VM supported limit on maximum number of LCPUs and partition supported limit on maximum number of cores. used to allocate CORBK table array. This is a limit on the number of cores AND the maximum allowed core address. 0138 312 Dbl-Word 8 * (0) 0138 312 Signed 8 RCCSTPST TOD value at last system timer pop interval 0140 320 Signed 8 RCCSTPT Smoothed total processor time (microsec) in last time interval The RCCTOPDX contains the index into the VMUTOPDA array that was used during the last rebalance operation. This field is used to maintain the VMUTOPDA array such that the Nth entry of each array for every VMUBK is for the same rebalance operation. RCCTOPDX is also used as an index into the SRXNICPF, SRXLIUSG, SRXVMDCT, SRXACGUS and SRXNIPAD, all fields related to rebalance and park/unpark operations. 0148 328 Bitstring 1 RCCTOPDX Zero based index into the most recent element in the SRXNICPF, SRXLIUSG, SRXVMDCT, SRXACGUS, SRXNIPAD, and VMUTOPDA arrays. This field is serialized by the same mechanism as the rebalance operation. It is updated by HCPHIPTM and used by park/unpark calculations (HCPHIC) and rebalance (HCPDSBRB). 0149 329 Bitstring 3 * Reserved for IBM use. 014C 332 Signed 4 RCCREBAL Count of the number of times a rebalance was done on this system. The following fields are used to build two arrays of origin VMUBKs for use by the DSVBK rebalance routine. Storage for the array is obtained at system IPL time. The arrays are rebuilt each time the guest CPU usage prediction routine is called. The prediction routine is called by the Periodic HiperDispatch routine before it calls the rebalance routine. There are two arrays built because rebalance wants to assign new home DSVBKs first to the guests with the largest predicted future CPU usage. So the first array is built unordered at the beginning of this buffer and then a quick sort is done to order them by predicted usage. The second array is maintained at the end of the buffer working backward through the buffer. This This array contains all origin VMUBKs whose predicted CPU usage is below a certain threshold as defined in HCPVMU. This second array is built to make the quick sort as efficient as possible by keeping the potentially large number of inactive guests out of the array that needs to be sorted. There is very little difference in the predicted CPU usage of all of these guests and so no real need to sort them. Serialization of these arrays is accomplished with the RCCVMULK defer lock. This lock is obtained at the time the arrays are populated with VMUBK addresses. This is done early in the Periodic HiperDispatch routine which is driven once every two seconds. The lock is held from the time population of the arrays begins until near the end of the Periodic HiperDispatch routine processing when the rebalance function completes. This lock is held to ensure no VMUBKs in either array can be released by logoff before all of the rebalance function completes. Note that because this lock is obtained early and held continuously across most of the Periodic HiperDispatch routine, other locks are obtained after RCCVMULK was obtained. Therefore RCCVMULK must always be obtained prior to obtaining any of the following: vary lock, scheduler lock, topology lock. An entry (element) in the arrays consists of two fields which are mapped by the VMUARYEN DSECT in HCPVMUBK: 1) a fullword pointer to an origin VMUBK 2) a fullword CPU usage value which is a scaled percentage of the guest's total predicted CPU usage for the next interval. 0150 336 Dbl-Word 8 RCCVMULK (3) Defer lock used to serialize the ordered and unordered arrays of VMUBKs (see lock heirarchy info in the block comment above) 00000100 RCCVMUPC 256 Count of pages of contiguous storage to reserve at IPL time for these arrays. This number is enough to have origin VMUBKs for 100,000 guests plus 20,000+ extra for things like AT command VMDBKs. A CKMAINT macro invocation in the module that obtains this storage verifies it is enough. 0168 360 Address 4 RCCVMUOA HLA start address of the ordered array of origin VMUBKs 016C 364 Signed 4 RCCVMUOC Count of the number of elements in use in the RCCVMUOA array 0170 368 Signed 4 RCCVMUUC Count of the number of elements in use in the RCCVMUUA array 0174 372 Address 4 RCCVMUUA HLA addr of 1st entry in array of origin VMUBKs with small predicted CPU usage. This is at the end of the storage buffer that starts at the address in RCCVMUOA. This array will be filled in by backing up into the buffer 0178 376 Address 4 RCCVMUPP HLA pointer to a one-page buffer to be used as a work area by the VMUBK array sort routine and also by the dispatch vector rebalance routine 017C 380 Signed 4 * Reserved for IBM use. Other fields used for HiperDispatch. The WHIBK pointer and the WHIBK control block are serialized by restricting their use within a loop of sequential routines which execute after a timer pop. These fields are modified by HCPWHI and viewed by HCPHIC. These routines cannot be re-entered until the next timer pop because a single TRQBK is repeatedly used for this purpose and it is not re-stacked by the calling routine until all of the routines complete. 0180 384 Dbl-Word 8 * (0) 0180 384 Signed 4 RCCWHIBK HLA pointer to the WHIBK, obtained and used by HCPWHI for white-space predictions. 0184 388 Signed 2 RCCCPUCT (24) Array of counts of CPUs which are associated with DSVBKs, indexed first by CPU type, then by polarization. Serialized by the topology lock. Counts include dedicated CPUs. 00000030 RCCCPUCT_len *-RCCCPUCT Length of array Similar to RCCWHIBK above, RCCNUPK is serialized by being set and used in sequential routines executed after a timer pop. RCCNUPK is set in HCPHIC when the decision about which CPUs should be in the unparked state is made. RCCNUPK is later used when creating the park/unpark decision monitor event record. The timer is not restacked until after the monitor record has been generated, thus preventing HCPHIC from running again and modifying this field until it has been consumed. 01B4 436 Signed 2 RCCNUPK (6) Array of counts of CPUs that are requested to be in the unparked state for the next interval, indexed by CPU type. RCPU side car trace table token. No serialization is needed, as the RCCTRACE field is modified only at initialization. 01C0 448 Signed 4 RCCTRACE Token for RCPU function trace table. Similar to RCCWHIBK and RCCNUPK, RCCOSCCT is serialized by being set and used in sequential routines executed after a timer pop. RCCOSCCT is used in HCPHICCC to decide whether to leave one extra CPU unparked to avoid park/unpark oscillation. 01C4 452 Signed 2 RCCOSCCT (6) Array of times in a row that HCPHICCC has predicted it will need exactly one less CPU than it currently has unparked. Indexed by CPU type. These arrays are allocated for two purposes: 1. When CP is running in a dedicated partition, they (RCCTUTIL and RCCTTIME) are used in calculating utilization which must be done differently when the logical processors are dedicated to physical processors. 2. Calculating a (per-CPU-type-pool) T/V ratio. That is, within a given CPU type, a ratio of non-wait execution time to guest emulation (run under SIE) time. This is used when making park/unpark decisions to gauge the potential MP overhead savings by parking a CPU. The arrays have MAXRPROC doubleword entries and are indexed by cpu address. At each interval the value of non-wait execution time in microseconds since the CPU was brought online is calculated using PFXTMSYS and PFXUTIME. HCPWHI calculates utilization for the interval as the difference from the non-wait execution time of the prior interval. The same calculation is performed for guest emulation time. 01D0 464 Address 4 RCCTUTIL HLA pointer to the array of interval utilization in micro- seconds calculated from PFXTMSYS and PFXUTIME since the last interval. 01D4 468 Address 4 RCCTTIME HLA pointer to the array of non-wait execution time in microseconds calculated from PFXTMSYS and PFXUTIME. 01D8 472 Address 4 RCCVUTIL HLA pointer to the array of interval utilization in micro- seconds calculated from PFXPRBTM since the last interval. 01DC 476 Address 4 RCCVTIME HLA pointer to the array of guest emulation time in microseconds calculated from PFXPRBTM. These fields are used to record the duration of HCPSGRSP SIGP Restarts. Monitor record MRPRCPUP (D5R16) records the duration and count in the D5R16 record. Note, however, that RCCSIGTD and RCCSIGCT include SIGP Restarts for operations unrelated to processor parking. 01E0 480 Dbl-Word 8 RCCSIGTM Work area for timestamp used to calculate the duration of SIGP restart operations. Serialized by vary proc lock. 01E8 488 Dbl-Word 8 RCCSIGTE Work area for timestamp used to calculate the duration of SIGP restart operations. Serialized by vary proc lock. 01F0 496 Dbl-Word 8 RCCSIGTD Cumulative duration of time spent in SIGP restarts expressed as the sum of the TOD clock increments between the time the SIGP restart started and returned. Serialized by vary proc lock. 01F8 504 Signed 4 RCCSIGCT Cumulative count of successful SIGP restarts. Serialized by vary proc lock. 01FC 508 Address 4 RCCLPDCY Address to a copy of the previous diagnose x'204' data buffer. We copy the buffer just before we issue a new diagnose x'204' so that we can compare between the previous and current intervals data. RCCxCAPy: CPU Capability formats from STSI 1.2.2 in integer and binary floating point formats. - If the secondary value (integer or BFP) is zero, then all processors have the same capability, reflected in the primary value. - If the nominal value (integer or BFP) is zero, then processors are currently operating at their nominal capability, reflected in the primary or secondary value. - Integer values are rounded from BFP values, except that a near-zero BFP value is rounded up to integer 1. Function : In zEC12 and earlier machines, STSI 1.2.2 reports only integer values for CPU capability fields. In z13 and later machines, the CPU capability is given as an integer or as a binary floating point number. We want to store both values for all architectures for monitor and accounting records' backward compatibility.

Rows of the table are indexed by values of PFXCPUTY. Rows of the table are mapped by the RCCHMTDS DSECT. The table is allocated during initialization by HCPIOP. Row count is RCCHMTCT. Row length is RCCHMTLN. 00000006 RCCHMTCT 6 Count of rows (CPU types) in the table. Historic HISMT metric values The historic values are kept in fullword arrays indexed by ProcClass. The arrays are only updated by the HISMT service when invoked by the MTC Timer Task. The serialization for updates to the arrays is provided implicitly by the fact that there is a single instance of the task in the system. These arrays are initialized to default values at CP initialization. The default for all values will be 1 with the scaling HISMT uses which is defined by HisMT_Entry_kMetricFactor to be 1024. 0280 640 Address 4 * (0) Force a cross reference 0280 640 Address 4 RCCHPROD (5) ProcClass historic values per ProcClass. 0294 660 Address 4 RCCHCAP (5) CapClass historic values per ProcClass. 02A8 680 Address 4 RCCHMCAP (5) MaxCapClass historic values per ProcClass. 02BC 700 Address 4 RCCHCBF (5) CBFClass historic values per ProcClass. 02D0 720 Signed 8 RCCSTPCR Time of second to last system timer pop interval Processor Pool information. 02D8 728 Bitstring 1 RCCPLFLG Processor Pools flag byte. 1... ....
