This document contains illustrated descriptions of the tables used by the
TOPS-10 monitor to allocate memory, to control jobs and resources, and to
provide information.

.FG7
TOPS-10 Monitor Tables Descriptions are the result of the effort to
document and illustrate information that system analysts and programmers
might need to repair or modify TOPS-10 monitor source code. This document
is provided by the Software Publications department for LCG Software
Engineering without guarantee of technical accuracy.
.b
The tables are simply an extension and summary of the monitor source code.
To the inexperienced user, they may seem bewilderingly complex. However,
to the user with experience in TOPS-10 monitor internals, and in the
TOPS-10 data structures, this document can be a useful reference for a
conceptual view of the monitor.
.b
The monitor source code itself is complex and lengthy, since it supports
many types of hardware and many software applications. The code does not
regard the support status of any product, and this document follows suit.
For complete information about product support, refer to the current
TOPS-10 Software Product Description.
.b
This document is only a summary of the information written and processed by
the monitor. It is an effort to record the information critical in
developing and maintaining TOPS-10. Do not assume this document is correct
in all cases. Please refer to source code listings of the appropriate
modules whenever using the information in these tables.
.b
The data structures for the ANF-10 network software are listed at the end
of this document, in Appendix A.
.b
The monitor tables are listed to reflect a TOPS-10 operating system based
on one or more KL processors. The information will be different for any
other type of system.

gain access to a specific version of a specific file.
.b
One table for each existing version of each open file.
.b
The access table for the current and possibly a superseding version
of the file are linked to the corresponding NMB. Also, each disk
device data block contains a pointer to the access table for the
file currently being accessed.

.le;When all users have closed a file, its access table is considered dormant.
Dormant access tables are linked into a doubly linked list through
ACCDOR, and are not deleted until their core space is needed. If
a table is not dormant, ACCDOR contains zero.

Notes:
.f;.ls;.le;Normally there is only one ACC linked to an NMB. But
while a file is being superseded, both the old and the new
versions of the file have ACCs linked to the NMB.
.le;The low order two bits of a pointer to another ACC will be zero.
The pointer back to the NMB points to Word 2 of the NMB, NMBACC. Hence,
its low order bits will not be zero.
.le;There may be an arbitrary number of ACCs for older versions of
a file, which are still being read. However, these ACCs are not
linked to the NMB. The only pointers to them are in the DDBs of the
readers.

Name: CDB -- CPU Data Block
.b.lm15.ts15.i-15
Description: There is one CPU data block for each CPU in the system.
The block contains both a constant and a variable data area, in contiguous
address space. Routine addresses, pointers, bit masks, and
processor-dependent instructions are representative of the data found in
the CPU Constants Area. The CPU Variables Area is cleared at initialiation and
on 403 restarts. This area contains current status words for the CPU,
including current job information, protected job data locations, scheduler
and swapper parameters, and so forth.
.b
References can be made to a CDB location without indexing. The symbols
used in this case will be in thr form of .Cnxxx, where n is the CPU number
(such as .C0xxx, .C1xxx, .C2xxx, and so on).
.b
A "C" macro is used to generate labels and data for the Constants Area.
A "V" macro is used to define symbols and allocate space for the Variables
Area. No data is generated by a "V" macro call. The "C" and "V" macro
calls are contained in the CDB macro, which is expanded once for each CPU.

All CDB symbols in the following tables require a prefix of .CP or .Cn,
where n is the CPU number. The Variables Area contains "Old CDB Symbols"
that were used to refer to locations in pre-5.04 versions of the monitor.

Notes:
.ls.le;CKF-CLKFLG (1105) This location takes the place of a hardware
interrupt flag.
.le;TMF-TIMFF (1106) Set so clock interrupt routines will know another
jiffy has passed.
.le;SCF#-#(1107) Normally clock interrupts are dismissed when they
interrupt exec mode. This flag is set after monitor detects an error and
desires to force rescheduling.

.b
Position of entry in table is of no importance. Each entry occupies 2
words.
.b
Each count is decremented by clock-level service in the monitor. When any
ountdown reaches 0, (or goes negative), the contents of the
second word of the entry are put into T1 and a PUSHJ is done to
the address in the left half of the first word.
.b
CLOCK is a 36 bit byte pointer to the highest in-use entry. Routines which
make requests to be stored in this table will reference CLOCK. When
an entry is eliminated from the table, the last entry is copied
into its place, and CLOCK is decremented.

Name: Disk Cache Data Structure
.b.lm15.i-15
Description: The data structures described in this section are used by
the monitor to implement a software disk cache.
.b
The basic data structure consists of two doubly-linked lists, a list header,
and a hash table. Each node in the list contains forward and backward
pointers for each of the two lists to which it is linked (the pointers are
_.CBNHB, .CBPHB, .CBNAB, and .CBPAB), a UDB address (.CBUDB), a block
number (.CBBLK), and a pointer to the address in FRECOR (.CBDAT) where the
block is stored. For statistics purposes, the node also contains a count
of the number of times this block has been hit since it was in the cache,
named (.CBHIT).
.b
The list header points to the two linked lists. The first linked list is
the access list. The most recently accessed block is at the head of the
list; the least recently accessed block is at the bottom of the list. This
list is linked through the .CBNAB/.CBPAB words. The second linked list is
the free list. It contains a list of all blocks that are not currently in
use, and as such do not appear in the hash list described below. This list
is linked through the .CBNHB/.CBPHB words.
.b
The hash table consists of pointers into the .CBNHB/.CBPHB list for the
corresponding list for blocks that hash to the same position. Thus, the
hash table is really a number of separate list headers for the lists of
blocks that hash to that position in the hash table.
.b
At initialization time (CSHINI), all the blocks are allocated and linked
into the free list. They are also linked into the access list. The hash
table entries are linked to themselves because the table is empty.
.b
To find an entry, given its UDB and block number, hash the block into the
hash table, and, using that entry as a list head, follow the list until you
find a match or return to the header. This is done with the routine
CSHFND. In general, these lists are one or two blocks in length.
.b
The main cache handling routine is CSHIO, which simulates I/O from the
cache, doing the necessary physical I/O to fill and write the cache. Note
that this is write-through cache, so no sweeps are required and the data in
the cache always reflects the blocks on disk.

Name: DDB -- Device Data Block
.TS15.b.lm15.i-15
Description: Contains information needed to perform I/O
operations. One such block exists for each device or, in the case of
disk, one for each INIT or ASSIGN.
.b
Number of entries in the DDB varies with the device.
.b
The label of a DDB entry is defined as the location of that
entry relative to the beginning of the block. Such labels
must be indexed by an AC containing the address of the beginning
of the DDB. AC F is normally used for this purpose in the monitor.
.b
The start of the DDB chain is accessible as GETTAB item %CNDEV from a
user program, or in location DEVLST in the monitor. DDBs for some
peripherals have their own tags in the monitor and some sub-chains
are also tagged:
.nf .b
TTYLST - Start of TTY sub-chain
PTYLST - Start of PTY sub-chain

.le;Only a "long dispatch table" contains entries DEN and DMT. The long
dispatch table is used for directory-oriented devices (DECtape, disk, and
labelled magtape).
.le;The actual tables are defined in the device service routines.
The base address of the device dispatch table is contained in the
corresponding Device Data Block, in the right half of DEVSER.
.le;The device dispatch table labels are normally indexed by
AC T4, which must contain the base address of the appropriate table. The
dispatch is usually performed by a PUSHJ P, Dxxx(T4) where Dxxx represents
the label of the appropriate table entry.
.le;Before attempting to dispatch to any of the long dispatch
table entries, the monitor checks the DVLNG bit of DEVMOD in the
Device Data Block for that device.
.le;The actual names of the tables are xyzDSP where xyz is the three-letter
name of the device (for example, PTRDSP for the paper tape reader).

Name: EXE Format Save Files
.b.f.LM15.I-15
Defined in: S.MAC
.b.i-15
Used by: COMCON, SEGCON
.B.i-15
Description: The old .SAV, .LOW, .SHR, .HGH and .XPN files have been
replaced by the .EXE type in order to provide a unified format
for saved core image files.
This type of file consists of two distinct but related portions:
.b.ls.le;Information about the structure of the file
.le;The data in the file
.els.b
The file information is organized into a variable number of chunks.
Each chunk begins with a word containing an identifier code in the left
half and the length of the chunk in the right half. At this time, the
defined codes are:
.ls
.le;Directory: 1776
.le;End: 1777
.els
Other chunks may be added later as they become necessary. The save file
starts with a directory followed by one or more pages of data. All
pages of data are stored on page boundaries in exactly the form they
will be loaded into the virtual address space. There is no zero
compression within pages; only entire pages will be compressed.
.b
The format of the directory is:
.lm0.b2 .nf
+---------------------------------------------------+
0 | 1776 | Size of directory |
|---------------------------------------------------|
1 | Flags | File page number |
|---------------------------------------------------|
2 | Repeat | Process page number |
|---------------------------------------------------|
/ Enough data to describe all pages /
/ /
+---------------------------------------------------+
.pg.f
Word 0 has 1776 in the left half and the size of the directory
in words in the right half.
.b;Word 1 has flag bits in the leftmost nine bits and a file page
number in the right 27 bits. If the file page number is zero then the
page is allocated but zero. The flag bits are:
.b.nf
Bit Symbol Meaning
.b
0 SV%HIS Set if this is part of the hiseg
1 SV%SHR Set if this page is sharable
2 SV%WRT Set if the page may be written
3 SV%CON Page is concealed (access by PORTAL only)
.f.b
Word 2 has a repeat count in its leftmost nine bits for one
less than the number of consecutive file and memory pages described
by this pointer. The rightmost nine bits describe the process address
into which this page should be loaded. Descriptors in the same format
as words 1 and 2 are provided for every contiguous piece of the process
space with identical access bits.
.b;A typical save file directory for a program with a 2K lowseg and a
10K hiseg would contain:
.b.lm 10 .nf .nj
001776,,000005
100000,,000001
003000,,000000
600000,,000005
023000,,000400
001777,,000001
.lm 0 .f .j .b
followed by 506 words of zeroes.
.b;_.EXE files were implemented to provide an extendable description of
a core image not limited to 256K. This is especially useful in taking
crash dumps of systems greater than 256K. Aside from this, the basic
advantages include only 1 LOOKUP to get a program as opposed to as many
as 3 previously, and the elimination of the overhead associated with
expanding zero-compressed core images and compressing them on a SAVE.
The disadvantages are that .EXE files require more disk space because
of the directory and the elimination of zero compression within pages,
and that an additional page, the directory, must be read when the core
image is fetched.

Description: Contains the master job queues. Each queue is an
ordered list of job numbers corresponding to all the jobs
in some particular status. There are two sets of queues, one
for jobs that are in core and one set for jobs that are swapped out.
.b
The index in the positive direction relative to JBTCQ is by job
number. The index in the negative direction is the queue number
for the in-core master queues and the queue number offset by the
maximum number of queues for the out-of-core master queues.
.b
Each queue is an ordered list of job numbers. In JBTCQ, each queue is
represented by a forward and backward linked ring of table entries. Each
ring begins and ends with a "queue header" entry at the position equal to
the negative queue number. A job number in the queue is represented by the
entry at the position equal to the job number. This entry contains
pointers to the preceding entry and the following entry, thus establishing
a unique position for that job number within the queue.

Job queues keep track of a job's priority to run and to be in core and are
maintained in table JBTCQ. Wait State Codes keep track of the runnability
of a job and are defined in parallel so that a queue number and a wait
state code that have the same meaning will also have the same numeric
value. Values will differ at different sites due to conditional assembly.

Key to Usage:
N No queue header for this WSC. (JBTCQ+0 contains
0). Defined in QUEUES macro.
U Wait State Codes for jobs that have become unblocked
but need to be processed by QREQ in SCHED1 before
being considered to run. Defined in QUEUES macro.
R Wait State Codes for jobs that blocked at UUO
level requiring a sharable resource that was unavail-
able (see REQTAB). Jobs will be unblocked by the
scheduler when the resource becomes available (see
AVALTB). Defined in RWAITS macro.
C Wait State Codes for jobs that are blocked waiting
for a monitor event, such as I/O complete, clock ticks,
command input, or DAEMON activity, before they will be
runnable. Defined in CODES macro.
Q These queues in JBTCQ actually hold jobs. Other
symbols have queue headers reserved for them, but
jobs are never placed in them. RNQ has no queue
header at all.
.el
.b2;.LM0
Notes:
.f;.ls;.le;RNQ, IOWQ, DIOWQ, PIOWQ, WSQ, TSQ, DSQ, and
PSQ never actually hold jobs. The queues are defined only to define the
corresponding Wait State Codes.
.le;The values of PQ1, PQ2, CMQ, and STOPQ are never used as wait state
codes. Jobs in any of the PQs have wait state codes of 000. When jobs
are put into CMQ or STOPQ they retain their previous codes, so that they
can be returned to their previous queues.

Description: Disk block containing descriptive information
about a file. There is one prime RIB for each file. If a file
needs more retrieval pointers than can fit in a single RIB, a
second (extended) RIB block is allocated to hold the additional

clusters. They may or may not be set. (Function of hardware sector length.)
.le;Each SAT block has a corresponding entry in the Storage Allocation

Name: Terminal Chunks
.b;.lm15;.i-15
Description: Used to hold characters that need to be typed on a
terminal, or characters received from a terminal and not yet read by a
program.
.b
Buffers are set up dynamically, as needed, from a pool of monitor
free core reserved for that purpose.
.b
The association between a buffer and a line depends on pointers in
the Line Data Block.
.b
Buffers are built from four word "chunks," which are linked together
as necessary.

Notes:
.f;.ls;.le;The ninth bit in each byte of data is used to indicate image mode.
.le;If there is not another chunk in a given direction, the corresponding
linkage will be zero.
.le;All chunks that are not part of a buffer are linked together to form the
"free list". The word TTFTAK points to the oldest chunk in the free list,
and word TTFPUT points to the newest chunk in the free list.
.le;The size of an individual buffer is limited by program
action. An output buffer cannot exceed 80 characters. If an
input buffer exceeds 172 characters (value of symbol TTIWRN) each
receive interrupt will force the output of an XOFF. If an input
buffer contains 300 characters (symbol TTIMAX) no additional
characters will be accepted from that line. A bell will be
substituted for the echo of a lost character.
.le;See description of Line Data Block for various pointers
which are used with the TTY buffer.

A zero entry indicates no attached terminal, otherwise, right half is
controlling DDB for the job. There is always a TTY DDB for every job, even
though no TTY need be attached. Thus, UUOs look through TTYTAB(n) for a DDB
because UUOs come from jobs.

For CALL UUOs, a table lookup is done in UCLTAB to get routine number; for
CALLI UUOs the number is supplied directly. One half of this routine number
is used as the table index. The left half is taken for even numbers; right
half for odd. UUOCON then dispatches to that address.

UCLJMP has entries corresponding to entries in UCLTAB. Table
entries may be added in the negative direction by customers, and
in the positive direction by DIGITAL (DEC). Once a table entry is
established, its position can never be changed without
invalidating those programs that use the corresponding CALLI.

Name: UCLTAB -- CALL UUO Names Table
.b.lm15.i-15
Description: Contains names of the CALL UUOs. There is one entry for
each CALL function.
.b
Indexed by corresponding CALLI value. Customer defined CALLs
have negative index values; DEC CALLs have positive values.
Table entries are SIXBIT expressions of the CALL names. There
are corresponding dispatch addresses in the UCLJMP table.

Notes:

as many of their own CALLs as desired.
.le;The value specified in a CALLI UUO corresponds to the position
of the CALL UUO name in this table. Hence, once an entry is established,
its position in the table can never be changed without invalidating any
existing programs that use that CALLI.
.le;All CALLs above CALLI AC,55 do not have a corresponding CALL with
a SIXBIT argument. In the future, only CALLIs will be added by DIGITAL.
