Can be changed with PCLONLY page serialization by tasks allowed to use PCLONLY. Set by page fault fastpath. Note that when setting this bit or when resetting it and turning on the PGSZBIT bit, the relocation change bit, PGSLGRCC needs to be turned on. .11. .... PGSHOST PGSRCPHR+PGSRCPHC PGSHOST Mask for host bits ...1 .... PGSLGRCC X'10' PGSLGRCC VMRELOCATE Content Change bit. Initialized to one. Changed only when holding PCLONLY or SHORT (including ERRSHORT). Known in architecture as PGSHCB. .... .1.. PGSGREF X'04' PGSGREF Guest backup reference bit .... ..1.

PGSINVAL X'80' PGSINVAL No auxiliary storage assigned Notes : PGSINVAL, in combination with other PTE, PGSTE, and storage key status bits, is used by steal processing to identify first time reference pages of zeros which have never been re-referenced or changed and can simply be discarded. The "first time reference page of zeros" state is identified by the following bit combination: noformat PTE: PAGINVAL=0 (page is valid and resident) PGSTE: PGSINVAL=1 (no DASD slot assigned) PGSRCPHR=0 (unreferenced) PGSRCPHC=0 (unchanged) Real frame storage key: Reference=0 (unreferenced) Change =0 (unchanged) enoformat Any resident page in this state is assumed to be unchanged zeros, and therefore simply discardable by steal. No page with non-zero contents should ever be allowed to be in this state, or a lost page will eventually result. The host change bit, PGSRCPHC, should be used to indicate that a page which is unchanged, not already on DASD, and non-zero, must be eventually written to DASD. * Note that both reference bits (PGSRCPHR and the real storage frame reference bit) can "evaporate" to zero over time due to the action of the reorder function. Therefore, the fact that a frame has been referenced, or setting PGSRCPHR on, can not prevent a page from eventually entering this "first time reference page of zeros" state. .1.. .... PGSSHARE X'40' PGSSHARE Page is a shared page ..1. .... PGS1READ X'20' PGS1READ ASA may be read only once. Used for shared pages. After the first read, this SDF (System Data File) ASA is to be ignored and the page left as changed. When the page is first written, it will go to a paging space ASA and this flag wil be turned off. PGS1READ on implies that page is read-only for the user. ...1 .... PGSALLOC X'10' PGSALLOC Page in the system address space (or a system-owned utility address space) that is allocated, OR A shared CP page in the monitor DCSS that CP has translated and that has not yet been released by the user connected to the DCSS. When this bit is on: 1) For a system utility space, the page is never part of a DASD block; 2) The associated PGMBK is never paged out. .... 1... PGSFIXED X'08' PGSFIXED Storage slot permanently assigned >>PGSPGMIO was PGSIO1ST, PGSIO2ND .... .1.. PGSPGMIO X'04' PGSPGMIO Indicates that pageable PGMBK I/O has not completed (PTRM page). Set when the first I/O completion interrupt is processed, reset when the second I/O completion interrupt is processed. Note the I/O can complete in either order. >>PGSPGMIM was PGSIOMSK 0803 2051 Bitstring 1 VPGGSSTA Virtual Page Status bits 1... .... PGSALTPT X'80' PGSALTPT For a target PTE, indicates the definition of the page is in alternate page table pointed to by PGMGALTP. For a source PTE, indicates data was saved for the page. Source PTEs can be distinguished from target PTEs by PGMGALTP being 0. PGSALTPT must be turned off when assigning differentiated page contents to the target PTE. .1.. .... PGSPCL2 X'40' PGSPCL2 Page serialization bit. See serialization section of prolog for more information. ..1. .... PGSLTSER X'20' PGSLTSER Page is "Long Term Serialized". May only be on if PGSPCL2 is also on (though PGSPCL may be on as well) .... .... PGSXSTOR X'00' PGSXSTOR Page is in XSTORE .... .1.. PGSBLOCK X'04' PGSBLOCK This page is one page in a block of pages .... ..1. PGSRABI X'02' PGSRABI This page was read in as part of a block of pages. This bit can NOT be checked for PTRM pages, as it is redefined as PGSXSTMB in that case. RABI pages are made IBR when added to the frame list. .... ...1 PGSERROR X'01' PGSERROR Page is in error. A storage error was detected in this page and the page could not be recovered. See serialization section of the prolog for role this bit plays in page serialization. When this bit is set, VMDRSSFG.VMDRSSUE must be set in the VMDBK that owns the space. 0803 2051 Bitstring 1 VPGGMSTA Virtual Page (PGMBK) Status bits 0804 2052 Signed 4 * Reserved 0804 2052 Bitstring 1 VPGGSB4 Virtual Page Status (Byte 4) 1... .... PGSZBIT X'80' PGSZBIT Page-content-logically zero bit Only meaningful when the PTE is invalid. .1.. .... PGSNT X'40' PGSNT Guest no translation. When ON the guest page does not contain any DAT structures. ..1. .... PGSCLASS X'20' PGSCLASS The page class specifies which Delta-pinned-page-count array is to be used in maintaining pinned page counts. Page class 0 (bit is 0) specifies the DPPCA for base address space pages owned by user. Page class 1 (bit is 1) specifies NSS/DCSS imbedded shared pages. The page class 0 DPPCA resides in the ASCBK and is pointed to by SIEDPPCAO in the format-2 state descriptor (SI2BK). The page class 1 DPPCA resides resides in RSMBK and is pointed to by PFXDPPCAO in the prefix area. ...1 .... PGSOVFLW X'10' PGSOVFLW The pin count (PGSPINCT) has overflowed and the current value does not represent the total pin count. The remainder of the total pin count is contained in both PGSOVFL1 (a one bit pin count overflow used to control hardware interception) and PGAOVFLW in the PGAUX). PTE must be valid. Can be modified with PCLONLY page serialization by tasks allowed to use PCLONLY. Set by pin/unpin fastpaths, translation paths, and no-owned functions. Before setting PGSOVFLW, PGAUX should be cleared to ensure no residual data is present. .... 1... PGSPROCL X'08' PGSPROCL Indicates page is on the processed list. Turned on by machine or fast path processing when corresponding FRMTE is put on processed list. Turned off by HCPPLP processed list processing. Can be modified with PCLONLY page serialization by tasks allowed to use PCLONLY. Set by HPMA or fastpath validate page. See PFXPROCL definition comments in HCPPFXPG for additional rules regarding processed list usage and the setting of PGSPROCL. .... .1.. PGSCONRP X'04' PGSCONRP Indicates a content-replacement operation occurred on an HPMA Resolve host page function. Can be modified with PCLONLY page serialization by tasks allowed to use PCLONLY. Set by HPMA or fastpath validate page. .... ..1. PGSUS0 X'02' PGSUS0 .... ...1 PGSUS1 X'01' PGSUS1 .... ..11 PGSUS PGSUS0+PGSUS1 PGSUS .... .... PGSUSS 0 PGSUSS .... ...1 PGSUSU 1 PGSUSU .... ..1. PGSUSP 2 PGSUSP .... ..11 PGSUSV 3 PGSUSV 0805 2053 Bitstring 1 VPGGSB5 Virtual Page Status (Byte 5) 0806 2054 Bitstring 1 VPGGSB6 Virtual Page Status (Byte 6) 0807 2055 Bitstring 1 VPGGSB7 VPS (Byte 7) - Pin Count 0804 2052 Signed 4 VPGPPDBK 31-bit PPDBK address. Note that this 31-bit addr doesn't conflict with bit 0 of this fullword (bit 32 of the PGSTE), which is PGSZBIT. Valid only in invalid PTRM PGSTE, when PGMBK is on DASD, or as a transient condition when the PGMBK may be headed to DASD. Mapping for a ASA64 (ASATE) Each ASA table entry is 8-bytes, with the following format: +------+-----+-----+-----+-----+-----+-----+-----+-----+ | Byte | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | +------+-----+-----+-----+-----+-----+-----+-----+-----+ | ECKD | -C | CC | cc | cc | PP | VV | -* | $- | +------+-----+-----+-----+-----+-----+-----+-----+-----+ | FBA | -P | PP | PP | PP | PP | VV | -* | $- | +------+-----+-----+-----+-----+-----+-----+-----+-----+ | Bits | 0- 7| 8-15|16-23|24-31|32-39|40-47|48-55|56-63| +------+-----+-----+-----+-----+-----+-----+-----+-----+ | Notes : | | - unused/available, zeros | | * reserve B'0110' for I and P bits when in PTE, rest| | available | | $ reserve B'1000' for encryption bit, rest available| | | | When ASA is a PRBN, it is contained in bytes 0-3 and| | bytes 4-5 will be 0. | Although we treat a standard ASA as a 48-bit value (see VPGGASA48), only 44 of those bits are actually relevant. The high-order 4 bits (bits 0-3) are unused and will be zero. When loading an ASA entry into a register, it's often convenient to have it in the low-order portion of the register. This could be accomplished as follows: LG Rx,VPGGASA48 SRLG Rx,Rx,16 However, another option which accomplishes the same, but also handles the possibility that bits 0-3 might be non-zero (perhaps a future enhancement wishes to use these bits) is as follows: LG Rx,VPGGASA48 RISBGZ Rx,Rx,20,63,-16 Since the RISBGZ is not a commonly-used instruction and is a bit complicated with so many operands, it's probably worth a little explanation. The RISBGZ instruction takes the 64 bits in a register (2nd operand), rotates them left a specified number of bits (5th operand), and then inserts a specific bit range of the result (3rd and 4th operand) into a register (1st operand), filling in any bits not specified in the range with zeros. In the above example, -16 specifies a right shift of 16 bits, 20-63 are 44 bits of the ASA we wish to retain which have now been shifted into the low portion of the register, and bits 0-19 will be zero. 1000 4096 Dbl-Word 8 VPGGASAT (0) VPGBK Aux Storage Address 1000 4096 Dbl-Word 8 VPGGANTR Auxiliary Storage Address 1000 4096 Signed 4 VPGGASA0 Word 0 of ASATE 1004 4100 Signed 4 VPGGASA1 Word 1 of ASATE 1000 4096 Bitstring 6 VPGGASA48 cylinder, page, volume portion (or page, volume for FBA) 1000 4096 Bitstring 2 VPGGASAx Cyl/page extension for large ASA (high-order 4 bits reserved and should be 0) 1002 4098 Bitstring 4 VPGGASA32 original CCPV/PPPV portion of ASA 1002 4098 Bitstring 3 * CCP/PPP 1005 4101 Bitstring 1 VPGGAVOL Auxiliary Storage Volume Code 1000 4096 Signed 4 VPGGPRBN For mapped-minidisk, PRBN uses the first fullword of the ASATE 1004 4100 Signed 4 VPGGAXSBN2 PTRM 2nd Xstore Block Number (XSBN). For PTRM PTEs only, when PGMBK is in Xstore (PGSXSTOR=1), contains the XSBN containing the second page of the PGM64. 1000 4096 Bitstring 6 * Bits 0-47 of ASA 1006 4102 Bitstring 1 VPGGAFLG ASA & Flags protect bits when PTRM PTE contains 2nd ASA for paged 8K PGMBK (to keep consistant formats) 1007 4103 Bitstring 1 VPGGASTA ASA status 1... .... VPGENCPT X'80' VPGENCPT Page is encrypted on auxiliary storage (DASD). The bit is set when an encrypted page is written. When a slot is returned this bit is turned OFF. Also, when a slot is allocated this bit should be OFF. When PGSINVAL is ON, the VPGENCPT bit has no meaning. Serialization for VPGENCPT is page SHORT.
