Library /sys$common/syshlp/SDA.HLB  —  SHOW  PAGE_TABLE, Qualifiers

1    /FREE 

    Causes the starting addresses and sizes of blocks of pages in the
    free PTE list to be displayed. The qualifiers /S0S1 (default),
    /S2, /GLOBAL, and /HEADER determine which free PTE list is to be
    displayed. A range cannot be specified, and no other qualifiers
    can be combined with /FREE.

2    /GLOBAL 

    Lists the global page table. When used with the /FREE qualifier,
    /GLOBAL indicates the free PTE list to be displayed.

3    /HEADER 

       /HEADER=address

    When used with the /FREE qualifier, the /HEADER=address qualifier
    displays the free PTE list for the specified private page table.

4    /GPT 

    Specifies the portion of page table space that maps the global
    page table as the address range.

5    /INVALID_PFN 

       /INVALID_PFN [=option]

    The /INVALID_PFN qualifier, which is valid only on platforms that
    supply an I/O memory map, causes SDA to display only page table
    entries that map to PFNs that are not in the system's private
    memory or in Galaxy-shared memory, and which are not I/O access
    pages.

    /INVALID_PFN has two optional keywords, READONLY and WRITABLE. If
    neither keyword is specified, all relevant pages are displayed.

    If READONLY is specified, only pages marked for no write
    access are displayed. If WRITABLE is specified, only pages
    that allow write access are displayed. For example, SHOW PAGE_
    TABLE/ALL/INVALID_PFN=WRITABLE would display all system pages
    whose protection allows write, but which map to PFNs that do not
    belong to this system.

6    /L1 

       /L1
       /L2
       /L3 (D)

    Specifies the level for which page table entries are to be
    displayed for the specified portion of memory. You can specify
    only one level. /L3 is the default.

7    /L2 

    Displays only the Level 2 page table entries for the specified
    portion of memory. /L3 is the default.

8    /L3 

    Displays only the Level 3 page table entries for the specified
    portion of memory. /L3 is the default.

9    /NONMEMORY_PFN 

       /NONMEMORY_PFN [=option]

    The /NONMEMORY_PFN qualifier causes SDA to display only page
    table entries that are not in the system's private memory or in
    Galaxy-shared memory.

    /NONMEMORY_PFN has two optional keywords, READONLY and WRITABLE.
    If neither keyword is specified, all relevant pages are
    displayed.

    If READONLY is specified, only pages marked for no write
    access are displayed. If WRITABLE is specified, only pages
    that allow write access are displayed. For example, SHOW PAGE_
    TABLE/ALL/NONMEMORY_PFN=WRITABLE would display all system pages
    whose protection allows write, but which map to PFNs that do not
    belong to this system.

10    /PT 

    Specifies that the page table entries for the page table region
    of system space are to be displayed.

11    /PTE_ADDRESS 

    Specifies that the range given is of PTE addresses instead of the
    virtual addresses mapped by the PTEs.

12    /SECTION_INDEX 

       /SECTION_INDEX=n

    Displays the page table for the range of pages in the global
    section or pageable part of a loaded image. For pageable portions
    of loaded images, one of the qualifiers /L1, /L2, or /L3 can also
    be specified.

13    /S0S1 

       /S0S1 (D)
       /S2

    Specifies the region whose page table entries are to be
    displayed. When used with the /FREE qualifier, indicates the
    free PTE list to be displayed. By default, the page table entries
    or the free list for S0 & S1 space is displayed.

14    /S2 

    Specifies S2 space as the address range. When used with the /FREE
    qualifier, /S2 indicates the free PTE list to be displayed.

15    /SPTW 

    Displays the contents of the system page table window.

16    /ALL 

    Displays the page table entries for all shared (system)
    addresses. It is equivalent to specifying all of /S0S1, /S2,
    and /PT.
