TBI_SINGLE_64 --- MMG$TBI_SINGLE_64

3.3.2 C Header Files Removed From SYS$LIBRARY:SYS$LIB_C.TLB

msb_codec_reg.h
msb_reg.h
vadef.h --- Moved to SYS$LIBRARY:SYS$STARLET_C.TLB

3.4 Removed System Data Cells

Table 3-3 lists the system data cells that have been removed as of OpenVMS Alpha Version 7.0.

Table 3-3 Removed System Data Cells
Removed Cell Replacement Comments

CTL$AL_STACK CTL$AQ_STACK Arrays are now quadwords.

CTL$AL_STACKLIM CTL$AQ_STACKLIM Arrays are now quadwords.

EXE$GL_GPT MMG$GQ_FREE_GPT As of Version 7.0, free GPTEs are managed in the same manner as free system PTEs. Note that 64-bit virtual addresses are required to access GPTEs.

LDR$GL_FREE_PT LDR$GQ_FREE_S0S1_PT Contains the address of the start of the free S0/S1 PTE list. The format of the free PTEs has changed for Version 7.0.

MMG$GL_FRESVA MMG$GQ_NEXT_FREE_S0S1_VA

MMG$GL_GPTBASE MMG$GQ_GPT_BASE As of Version 7.0, free GPTEs are managed in the same manner as free system PTEs. Note that 64-bit virtual addresses are required to access GPTEs.

MMG$GL_MAXGPTE MMG$GQ_MAX_GPTE As of Version 7.0, free GPTEs are managed in the same manner as free system PTEs. Note that 64-bit virtual addresses are required to access GPTEs.

MMG$GL_P0_PTLEN None Obviated by the removal of the process page tables from the balance slot.

MMG$GL_PX_VPN_LENGTH None This data cell is obviated by the removal of the process page tables from the balance slot.

MMG$GL_RESERVED_SVA MMG$GQ_WINDOW_VA Increased in length to quadword.

MMG$GL_RESERVED_SVA2 MMG$GQ_WINDOW2_VA Increased in length to quadword.

MMG$GL_RESERVED_SVAPTE MMG$GQ_WINDOW_PTE_PFN 64-bit pointer to PFN field of first reserved PTE.

MMG$GL_RESERVED_SVAPTE2 MMG$GQ_WINDOW2_PTE_PFN 64-bit pointer to PFN field of second reserved PTE.

MMG$GL_SHARED_L2PT_PFN None This cell was deleted since it is possible to have more than one shared L2PT. That is system space may span over multiple L2PTs.

MMG$GL_SPT_L2PTE_BIAS None This cell was deleted since it is possible to have more than one shared L2PT. That is system space may span over multiple L2PTs.

MMG$GL_VA_TO_PX_VPN None This data cell has been completely obviated by the removal of the process page tables from the balance slot.

MMG$GL_ZERO_SVA MMG$GQ_WINDOW_VA Increased in length to quadword.

MMG$GL_ZERO_SVAPTE_PFN MMG$GQ_WINDOW_PTE_PFN 64-bit pointer to PFN field of reserved PTE.

MMG$GQ_PT_VA MMG$GQ_PT_BASE MMG$GQ_PT_VA was renamed to ensure that any code that had assumed a fixed location of page table space as a function of page size would be revisited. The location of page table space is now variable to meet the individual bootstrap needs of supporting Version 7.0, as well as being a function of the page size.

MPW$GW_HILIM MPW$GL_HILIM Increased in length to a longword.

MPW$GW_LOLIM MPW$GL_LOLIM Increased in length to a longword.

PFN$GB_LENGTH None

PFN$PL_DATABASE PFN$PQ_DATABASE The PFN database was moved to S2 space, which is only addressable with 64-bit pointers.

PHV$GL_REFCBAS PHV$GL_REFCBAS_LW The process header reference count vector has been promoted from an array of words to an array of longwords.

SGN$GL_PHDAPCNT None This cell was deleted as a result of moving the process page tables out of the balance slot.

SGN$GL_PHDP1WPAG None This cell was deleted as a result of moving the process page tables out of the balance slot.

SGN$GL_PHDRESPAG None This cell was deleted as a result of moving the process page tables out of the balance slot.

SGN$GL_PTPAGCNT None This cell was deleted as a result of moving the process page tables out of the balance slot.

SWP$GL_L1PT_SVAPTE None L1 page table now mapped virtually in page table space.

SWP$GL_L1PT_VA None L1 page table now mapped virtually in page table space.

SWP$GW_BAKPTE None This cell was deleted as a result of moving the process page tables out of the balance slot.
