ASCBK Prolog
NAME : HCPASCBK DESCRIPTION: Address-Space-Control Block DSECT : ASCBK FUNCTION : Contain information about an address space. The ASCBK is essentially CP's software extension to the ASN-second-table entry (ASTE) describing the address space. LOCATED BY : ASTASCBK field of the ASTE defining the address space CREATED BY : HCPASMCR DELETED BY : HCPASMDS SERIALIZED : Many fields in the ASCBK are static for the life of the address space. Most of the rest of them are serialized by the ASCBK lock, the lockword for which is at ASCLOCK. Various fields are serialized by: - ASCBK lock (ASCLOCK) - MP Defer - Console-function mode - XSTSTATL COMMENTS : The ASCBK must reside on a doubleword boundary.
ASCBK Control Block Content
ASCBK DSECT
Hex Dec Type/Val Lng Label (dup) Comments ---- ---- --------- ---- -------------- -------- 0000 0 Structure ASCBK Address-Space-Control Block Address space management area. This area contains fields used to manage and locate the address space itself. All fields in this area are serialized by the ASCBK lock (the lockword at ASCLOCK) unless specifically noted otherwise. 0000 0 Address 4 ASCOFPNT Forward pointer to next ASCBK in chain of ASCBKs anchored from VMDASCBK of the owner's base VMDBK. This chain defines what address spaces are owned by the VMDBK. SYSTEM-owned spaces are anchored from the SYSTEM VMDBK. This field is serialized by the owner's ASCBK-queue lock (VMDASCLK). The chain is ended by a forward pointer of zero. 0004 4 Address 4 ASCSFPNT Forward pointer to next ASCBK in the chain of ASCBKs anchored from RSASHRSP in HCPRSM. This is the chain of shareable address spaces, and is serialized by the lock at RSASHRLK. The chain is ended by a forward pointer of zero. 0008 8 Address 4 ASCSBPNT Backward pointer to previous ASCBK in the chain of ASCBKs anchored from RSASHRSP in HCPRSM. The ASCSBPNT field of the first ASCBK in the chain is zeros. 000C 12 Signed 4 ASCSEQNO r-access sequence number, incremented on address space reset to match the ASTE sequence number (ASTSN). r-access i-ASITs (which use this sequence number) are sensitive to address space reset operations. 0010 16 Character 32 ASCSPCID (0) Space identification: 0010 16 Character 8 ASCUSRID Owning userid, padded on right with blanks. 0018 24 Character 24 ASCNAME Address space name, padded on right with blanks. 0030 48 Address 4 ASCSNTBK Pointer to owning SNTBK (ASCTSNT=1) 0034 52 Bitstring 4 * Reserved for IBM use 0038 56 Dbl-Word 8 ASCEASIT (0) ASCBK e-ASIT. 0038 56 Address 4 ASCASTE Pointer to ASN-Second-Table Entry (ASTE) for the address space. Serialized by task ownership at creation, thereafter unchanged until space is destroyed. 003C 60 Signed 4 ASCSCRSN Address space creation sequence number. 0040 64 Address 4 ASCSPIBK Pointer to chain of SPIBKs designating which users are permitted to attach this space to their guest-use access list. This field is serialized by the space-permission- manager lock (RSASPMLK in HCPRSMCM). 0044 68 Address 4 ASCOWNER Pointer to (base) VMDBK of owning virtual configuration, or SYSTEM VMDBK if CP owned. 0048 72 Dbl-Word 8 ASCLOCK (3) Lockword for shared/exclusive defer lock, protecting fields in the ASCBK and ASTE. For System Utility address spaces managed by HCPVAMAP and HCPVAMDP and HCPASURO, ASCLOCK exclusive is sufficient to invalidate a SEGTE without SEGTRANS. A share of ASCLOCK must be obtained *before* trying to obtain SEGTRANS when validating the SEGTE. .* .* -WAH-> The presence of discontiguous defined storage via -WAH-> DEF STOR CONFIG does not change the definition, though -WAH-> there is now no guarantee that all bytes below -WAH-> ASCHIBYT are defined or addressable (therefore, all -WAH-> references to "size" in the ASCHIBYT definition have -WAH-> been changed to "address limit"). 0060 96 Dbl-Word 8 ASCHIBYT The highest addressable byte of storage in this address space. The "address limit" of the address space in bytes is one greater than this value. Since X'FFFFFFFF_FFFFFFFF' is a valid address in ESAME, code must check for wrap-to-zero when adding one to ASCHIBYT to calculate the "address limit" of the address space in bytes. *NOTE** ASCHIBYT, in ESAME, is similar to, *NOTE** but not identical to, ASCSSIZE in *NOTE** ESA/390. 0068 104 Dbl-Word 8 ASCDEFSZ Defined storage size in addressable bytes, minus one. If DEF STOR CONFIG was used to define multiple discontiguous extents of addressable defined storage, this field contains the sum of the sizes in bytes of all of the individual extents (minus one). Minus one notation used so that a total size of 16 Ekabytes may be represented without ambiguity (as x'FFFFFFFF_FFFFFFFF'). 0070 112 Signed 4 * Reserved for IBM use .* .* End of ESAME build only code .* 0074 116 Bitstring 1 ASCSTATE Flags indicating current state Serialized by holding ASCLOCK exclusive, the owning VMDBK's PTIL exclusive, AND by Console Function mode on the owning user. 1... ....

Note: ASCSTS32 == STDSTL01 Notes : ASCSTSIZ may have values in between ASCSTS32 (32M) and ASCSTS1G (1G). In these cases the value represents the size of the segment table when a segment table is allocated from a free storage frame.

The following 4 fields are serialized by the available list replenishment demand scan test and set lock. 00E0 224 Address 4 ASC1STFR Address of the first FRMTE that was stolen from this address space in this iteration of the steal task. Each iteration will initialize this field to FF's and the FF's in a FRMTE's FRMFPNT indicates that it is the last FRMTE on the list. 00E4 228 Address 4 ASCSTLNX Address of the next ASCBK for a space stolen from in this iteration of the steal task. Each iteration will initialize this field to FF's. When the FRMTE's are all sorted (by address space), the last ASCBK in this chain will have FF's in this field. 00E8 232 Address 4 ASC1STPG Address of the first PGMBK that was stolen from this address space in this iteration of the steal task. Each iteration will initialize this field to FF's and the FF's in a PGMBK's PGMSTNXT indicates that it is the last PGMBK on the list. 00EC 236 Address 4 ASCLSTPG Address of the last PGMBK that was stolen from this address space in this iteration of the steal task. Each iteration will initialize this field to FF's and the FF's in a PGMBK's PGMSTNXT indicates that it is the last PGMBK on the list. 00F0 240 Signed 4 ASCITRCT Count of in-process i-access manual translations in the address space. 00F4 244 Signed 4 ASCRTRCT Count of in-process r-access manual translations in the address space. ESAME Region Translation Cache ASCR0STD, ASCR0RFT, ASCR0RST, and ASCR0RTT, are in ASCE format, that is, the bits which define the table level are DT bits (level of the designated table), not R*TE format TT bits (which indicate the level of the table containing the R*TE). Any ASCR0R*T fields corresponding to table levels higher than that designated by the current ASCE are set to zero. Serialization of these fields is as follows: For the entry designating the current highest level table for the address space (that is, the entry which matches the current ASCE), PTIL must be held exclusive. For all lower level table entries, either PTIL must be held exclusive, or a share of PTIL must be held along with RTETRANS in the next higher level R*TE which designates the same table. 00F8 248 Dbl-Word 8 ASCR0STD Rx=0 segment table designation 0100 256 Dbl-Word 8 ASCR0RFT Rx=0 region first table designation 0108 264 Dbl-Word 8 ASCR0RST Rx=0 region second table designation 0110 272 Dbl-Word 8 ASCR0RTT Rx=0 region third table designation 0118 280 Dbl-Word 8 * (3) Reserved for IBM use 0130 304 Signed 4 ASCMVABV Number of times a page in this address space with a frame address < 2G was moved to a frame with address >= 2G. 0134 308 Signed 4 ASCMVB2G Number of times page translation moved a page in this address space from a frame with address >= 2G to one < 2G. ESAME HDPBK queues - HDPBKs are the programming areas associated with host region and segment tables. To make traversal of sparsely populated tables easier, we keep several doubly linked queues of HDPBKs. The first HDPBK queue is the "addressable storage" HDPBK queue, containing queue is the "addressable" queue, and contains HDPBKs (potentially representing different table levels) for each addressable extent of storage, in ascending virtual address range order. The remaining HDPBK queues contain all of the HDPBKs for a given table level, again, in ascending virtual address range order. The region table(s) (if any) and segment table for region 0 are pre-allocated when the space is created. Therefore, an HDPBK representing region 0 will be the first HDPBK on each queue. Each queue header can also be mapped using the HDPQPTRA HDPBK Queue Pointer Area DSECT define in HCPHDPBK. >> Initialization and maintaining of these queues has >> been deferred until the initial code base is working, >> as these are primarily used as "accelerators" for >> routines which traverse HDPBKs... >> Queue headers will remain 0 until further notice. 0138 312 Signed 8 * (0) 0138 312 Bitstring 0 ASCHDPQS (0) HDPBK queue header area - space for 5 queues 0138 312 Signed 8 ASCADHDQ (0) Addressable storage HDPBK queue header - doubly linked queue of HDPBKs 0138 312 Signed 4 ASCADHDN Forward pointer to first HDPBK on addressable storage HDPBK queue.

ESAME Address Space Storage Configuration area This array contains address extent information for each defined address extent. For most address spaces, there will only be one extent defined, from 0 to ASCHIBYT. If the DEFine STORage CONFIGuration command was used to define multiple discontiguous address extents, this array contains one additional entry for each additional address extent defined. Up to eight extents are allowed, the first extent must begin at address zero. Individual array elements are mapped by STCONFIG DSECT. Array elements must be sorted in ascending virtual address order. Address ranges must not overlap, and must not be contiguous. 00000008 ASCSTELS 8 Number of elements in storage configuration array 0160 352 Signed 4 ASCSTCAE Number of additional storage configuration array elements used to represent the current storage config.
