ACTIVE OBJECT TABLE (ACT) AND ACTIVE SEGMENT TABLE lAST)
The AOT/AST is a wired system-wide table that describes the current state of active objects and their associated active segments. Each ASTE has enough information to identify the file segment and, through the associated AST_PMAPS, the location of each page of the segment. All virtual segments mapped to the same file segment will use the same ASTE entry. The AOTE acts as a cache of the VTOC entry. The table is dynamically allocated at startup based on physical memory size.

MSTE_PAGES is an array of pages that are wired as needed to support mappings in the mst. When a segment is mapped and the corresponding mst entry = mst_entry_free, a free page is found in the msteyages array and wired. It's number is put into mst [entry] . The number of pages that can be used is limited at boot time to be some percentage of physical memory. See mst_$init.
MEMORY MAP (MMAP)
For all machine types an MMAPE (rnmap entry) is 12 (decimal) bytes in size.

Notes on directories
1. To add an entry to a directory:
File System
A. Look for an unused entry in the linear list. If you find one, use it and you're done.
B. Hash the name you want to add:
- name is: array [1 .. 32J of CHAR
- lnth is useful lnth of name sum: =0; For i : = 1 to 1nth DO
sum : = ord (name [i]) +2*sum; HASH_VAL ,.. sum mod HASH_VALUE;
C. Get the hash thread for the specified hash value and call that value the found block.
D. If the found block number is 0 then we need a new entry block, so:
2-6 APOLLO CONFIDENTIAl. INTERNAL USE ONLY.
a) See if there are any blocks threaded through the free block list and if so, take one of those. Otherwise, bump the high block number and use that.
b) Initialize the newly obtained block, add it to the end of the apprpriate hash chain, add the new entry as the first entry in the new entry block and you're done.
E. If there is an unused entry in the found block, use it and you're done.
F. Change the found block value to the number in the current found block's NEXT BLOCK field and go to step D.
2. The searching rule for a directory is:
A. Look in the linear list.
B. Hash the name you're searching for.
C. Follow the hash thread for the specified hash value to the first entry block with that hash synonym.
D. Search all (3) of the entries in the found entry block
E. Follow the "next block number" in the found entry block to get a NEW found entry block. If the next block number is zero, then return NOT FOUND.
F. Go to step D with the newly found block.

DEBUG COMMAND EXTENSIONS
The fOllowing commands and other items are available in the standard DEBUG, but are not advertised to the public.
Apollo DEBUG Commands
a FPREGS -- Display the floating-point registers.
a REGS -- Display the registers of the target program.
o DB -- Invoke the machine-level debugger DB (see below) .
Opt ions t a DEBUG Commands
a -CDB -- This option is useful to debug C code in the C library. It prevents DEBUG from running to the "main" program when DEBUG is invoked.
a -ODD -- This option is useful only when debugging DEBUG from another DEBUG. It must be given to the target DEBUG only. When it is given, the target DEBUG will return from the fault handler with the "continue fault handling" state, so that the master DEBUG can catch breakpoints and -signal
steps.
Miscellaneolls
More help is available on DEBUG commands in this file:

Here is some useful information which IS PUBLIC, which
people often forget how to do.
There are three debugger names that DEBUG looks for. If it finds them, it does some special things:
'cr (macro name; made with MACRO command) 'max_array_dim (debugger variable; made with SET command) 'max_var_len (debugger variable; made with SET command)
Note that "help examine" explains the 'max_,.. names, and "help macro" explains the 'cr name.

CRASH ANALYSIS
Most fatal errors recognized by AEGIS are reported by the crash system routine, which prints a status code (see Chapter 4, Error Codes and Messages), the address of the ECB for the failing routine, and the ID (PID) of the current process. AEGIS then executes a TRAP instruction, causing entry to the PROM mnemonic debugger with an "S" code (see MNEMONIC DEBUGGER ERROR CODES in Chapter 4). A dump can then be taken as described below.
If the system appears hung, or to stop the machine at any time for debugging, make sure the NORMAL/SERVICE switch is in the SERVICE position and type CTRL/<RETURN>, to pass control to the mnemonic debugger (MD). To continue, type:
> G > G *+2 Then CTRL/<F>.
If this fails, press the RESET switch. (You should first verify that the hang is not a temporary one caused by a network failure.)
Notes on DNx6Q Crash Status
DNx60's are microcoded machines. They may crash as described above with a CRASH SYSTEM message, ending up in MD but still running the micromachine (the CPU - MD prompt is '>') or they may occasionally freeze, (i.e. the micromachine halts), ending up in MD but running the CPIO processor (MD prompt is' %'). When a freeze occurs, the micro PC is printed by CPIO:
uPC: xxx
You may still take a dump from CPIO exactly as described above. A freeze is a. more radical failure than a normal crash and usually indicates a hardware f.ilure in the micromachine.
APOLLO CONFIDENTIAL. INTERNAL USE ONLY. 5-15 System Debugging
SYSTEM DUMPS
AEGIS contains a memory dump routine that can be used to dump the state of physical memory and the MMU to a floppy diskette, a cartridge tape, or a file on another node. DB, which under stands the format of the dump, can then be used to analyze the cause of the crash. On completion, the dump routine executes a trap instruction and returns to the Mnemonic Debugger (MD).
To use this routine, follow these steps:
1. To dump to a diskette, insert a diskette into the floppy diskette drive of the Disk Storage Option. The diskette must already be formatted (with INVOL) for 1231 blocks, and must be write-enabled. (To write-enable the diskette, cover the write-enable hole with a gummed label.) (Note:
if dumping to a floppy, only the first 1Mb of memory is dumped. )
2. To dump to a cat ridge tape, insert a cartridge tape into the tape drive and ensure that the tape is not write-protected (arrow in the upper left should point away from nsafe n ) .
3. To dump to another node, make sure that the other node is running NETMAN and that its disk has enough space for the dump (30 blocks plus 1024 blocks for each megabyte of memory on the dumping node) .
4. Execute the following MD commands.
>RESET<RETURN> ><RETURN>
>DI F >DI C >DI N nn
FOR ALL NODES:
Reset the machine
To dump to a floppy To dump to a cartridge tape To dump to node nn
>G xOOCOO Start dump to floppy or tape >G xOOC04 Start the dump tn another node

System Debugging 5-16 APOLLO CONFIDENTIAL. INTERNAL USE ONLY.
5. When the dump routine is complete, it executes a TRAP $F instruction and returns to Me. You should then run SALVOL and reboot AEGIS.
6. To load the dump back onto a node in order to use DB, use the CPTAPE or CPFLP utility of the /SYSTEST/SSR_UTIL directory.
!SYSTEST!SSR .IlI.lL
The following commands are available for system debugging in /SYSTEST/SSR_UTIL.
o ALL_STCODE -- Displays a list of all the system status codes for this operating system revision.
a BCR -- BINARY_CROSS_REFERENCE produces a cross reference from a list of object modules, whose names are read from standard input. Only the global symbols referencable from outside the module are cross referenced.
Usage: BCR
o CMB -- Compare binary compares two binary files files output by-any Apollo compiler or assembler.
Usage: CMB source destination [-ERRLIM <n> J [-NODate1 [-List]
"Source" may be a wildcard. "Destination" is a derived name. Mul.tiple source/destination pairs may be specified. -ERRLIM may be specified to control how many differences per section displ.ayed; the default, is 1. -NODATE may be specified to ignore differences in the creation times. -List will list the names of the files being compared. Compare_binary uses the common command line handler; type HELP CL for info.

o DMPF -- DUMP_FILE dumps a file of any type to STDOUT interpreted in hexadecimal and ASCII. If hex_start_offset is given, it specifies the byte of the file at which to start dumping. If hex_end_offset is given, it· specifies the byte of the file at which to stop dumping. The first byte of the file is at offset O. By default Dump_file dumps the entire input file.
Usage: DMPF inputyathname [-From hex_start_offset] [-TO hex_end_offset]
o DMPMBX -- DMPBX formats the contents of an MBX (mailbox) file. This program gathers information to document MBX bugs or problems. You must use DMP.MBX from the same node as the server of the MBX file to be dumped. Normally, you use DMPMBX to display the contents of the MBX file just before the bug is found and just after the bug takes effect. In remote cases, both the server.MBX file, and the client node's 'node_data/sysmbx file should be dumped out.
Usage: DMPMBX mbx_file [-FD] [-CHAN channel_list])
o DTCB -- Dumps the contents of the TCE' control blocks associated with a particular TCE' connection. The address of the TCB to be dumped may be obtained using the TCPSTAT program. Two control blocks are dumped: the UCB (user control block) which contains the send and receive queues and user-related flags, and the TCB (TCP control block) which contains the connection sequence numbers, state, flags, and out-of-sequence queues.
usage: dtcb control_block _address
ARGUMENTS
control_block_address The hex address of the control block to be dumped, as displayed in the "TCB" field of a TCPSTAT report.
o FBS -- Used to find disk blocks whose data integrity is marginal. FBS DESTROYS ALL PREVIOUS USER DATA ON THE DISK. Following the "Show failing data?·" prompt, fbs will destroy all previous information on the disk except for the physical bad spot list. If second thoughts occur abort at this prompt or before.
For the number of passes entered, fbs writes then reads patterns of bits to all blocks on the disk. For those sectors which fail, their disk address is added to ~he physical list of bad

spots. FBS requires between one and five hours of running time for various sizes of Apollo disks.
Please refer to the appropriate appendix in the DOMAIN System Command Reference for complete information on the use of this software tool.
NOTE: The fbs utility is only valid on DNIOO, DN3xx, DN4xx, DNSxx, DN6xx, DSP80, DSP90, and DSPl60 series machines (machines with saul, sau2, sau3, sau4 or sauS). It is not valid on any other machine, and will become obsolete in the future.
o FIXCOM -- FIXCOM fixes comments in source files so that you can use the -COMCHK option when the file is compiled. For more information, see the file FIXCOM. HLP in this directory.
o FIXVOL -- FIXVOL is a general tool for examining and repair:ing disk volumes. with FIXVOL you can read, write, and examine arbitrary disk blocks (like RWVOL). You can maintain a stack of such disk blocks, examining th-em with the db program. FIXVOL will also repair LV and PV labels, the VTOC, or disk block headers. FIXVOL is fully interactive with the default mode being to prompt before making any destructive changes.
o FMPD -- FORMAT_PROCESS_DUMP formats a process dump and writes the formatted dump to standard output. Process dumps are made by the process manager when a process terminates abnorl;Tlally and appended to the file "'node data/proc dump". Information included is similar to that p~ovided by the FAULT_STATUS (FST) and TRACE_BACK (TB) commands.
Usage: FMPD [pathname ... J [-LAST]

All sections for all installed libraries are listed if no arguments are supplied.
Usage: GLOBMAP (-L library_wildcard ... ] [-5 section_wildcard ... ] {CL}
If the -L (library) option is specified, the sections for a11 libraries whose names match the wildcard are listed.
If the -S (section) option is specified, each section name that matches the wildcard is listed.
If both options are specified, both the library and section names must match the wildcard in order to be listed.
o INXLIB -- The binary file (s) with the given pathnames are installed as private libraries. Any entrypoints in the libraries that match entrypoints that already exiat in the known global table are treated specially, for example: If x. bin contains an entrypoint named error _ $print, following an
inxlib x.bin
any subsequent call to error_Sprint will first end up in the copy of error Sprint in x.bin. When that copy "returns·, the r;al error_Sprint will be called, and when the real error_Sprint returns, the copy in x. bin will be called again.
Uaage: INXLIB pathname... [-db)
Specifying -db will cause the old and new entrypoints of any replaced routines to be displayed.
For an example of how inxlib can be used, see lus/lib/mt/mtx.pas.
npathname n may be a wildcard. INXLIB uaes the common command line handler; type HELP CL for info.
a LLKR -- LLKR will take a pathname and, if it is locked, tell you by whom it is being locked, what node it is presently being locked, and the locking mode.
Usage: LLKR [pathname]

a JUMPER -- JUMPER is an interactive program that graphically displays the locations and functions of jumpers on all system printed circuit boards. JUMPER, which is completely menu-driven, makes use of the function keys (Fl to F8). Help is available in the file /SYSTEST!SSR_UTIL!JUMFER. HLP.
o LSYSERR -- LSYSERR writes the contents of a system error log to standard output. Help is available in the file LSYSERR.HLP in this directory.
o LTBL -- Prints the debug line number table
Usage: LTBL (enter object module)
a MBD -- MEMORY_BUFFER_DUMP dumps usage information about the TCP memory buffer pools. Usage statistics on TCP memory buffers may be obtained using the "-m" option of the TCPSTAT conunand; MBD
is intended for analyzing cases where buffers are being lost. MBD scans the entire buffer pool, finding all the chains of in-use buffers; it then prints each chain of buffers. This information may help you in discovering reasons why buffers are being lost.
Usage: mbd [-f) [-k]
OPTIONS -f - Dump the free pools as well as the chains of
in-use buffers. This produces a lot of output.
-k - Don't try to lock the mutex on the buffer
pools before doing the dump. This is useful mostly when the tcp_server has crashed with the buffer pool mutex locked.
o NETLOG -- NETWORK_LOG is a tool that can be used to monitor paging and segment activity on system. You will need two nodes: the node that is to be monitored and a node to collect the statistics.
The Netlog program is run only on the node gathering statistics; the n listening" node. Netlog has two subsystems: START and REPORT. For more information, invoke Netlog and type "help".
o OBJDMP -- Dumps an object (.bin) file
Usage: OBJDMP infile [-L[IST] [outfile 1-]]

o RINGLOG -- Monitors network traffic in and out of a node
Usage: RINGLOG [-start I -stop I -read]
-Start activate ring network message logging -Stop deactivate ring network message logging
-Read
(if active) and display current contents of the log. (This is the default!) display current contents of the log. (Different from STOP because STOP deactivates logging if it is active.
o RWVOL -- RWVOL reads one physical disk address at a time, and puts it into a buffer in memory. The program first asks you to specify the controller type, and then to specify whether you want to read (R) or write (W) the disk address. If you plan to write to the disk, first choose the "R" option to read the address first.
When you choose the "R" option, the program asks you to enter the physical disk address (Daddr:) to be read; enter it in hex. The program next asks you for the memory address to be used for the buffer containing the data it reads from the disk. If you are reading only one record at a time, you can issue a <CR> to use a default location for the buffer, which RWVOL then displays. If you specified a start address, you must specify an end address when prompted for it; otherwise just type <CR>.
After RWVOL displays the "Done" message, you can use DB (if you are running online), the Mnemonic Debugger (if you are running offline) to look at the contents of the record that you have read, in the location the program displayed for the buffer.
Usage: RWVOL
o TRPT -- TRANSLATE_PROTOCOL_TRACE prints the contents of the tcp debugging log in readable format. The log consists of entries for each transition of the tcp state machine for all enabled connections. The information recorded includes the old and new states of the transition, the type of the input that caused it, identifier for the connection, and for network input and output, the tcp sequence and acknowledge- ment numbers and packet flags, and a timestamp.

tracing, use the -C option.
Usage: trpt [-ejlnsw] [-p <TeB address>] [<file>]
OPTIONS
-e -- exit if an invalid log entry is found -1 -- print lapsed times between log entries
-w -- warn on invalid log entry diagnostic
-s -- print only tcp state info. -n -- print only net input and output
-t -- do not print timestamps
-j -- just print TCE addresses -C -- zero out the contents of the trace

-p <TeE address> .:..- print info only for this connection.
<file> -- file name to open instead of
'node_ data/tcp _data
a TS -- SHOW_TIME_STAMP displays the module name
and time stamp stored in an Apollo object module. Shown is the time and date that the module was
created by the binder or one of the compilers. The time stamp is not affected by copying an object module, so it is a reliable indicator of
whether particular object modules are copies of
one another.
Usage: TS object _module_name
a UPATH The UPATH command will return the
pathname of a uid given a specific uid. To get a uid directory type: ' Id (directory name) -u'
Usage: UPATH [uid] {CL}
o XMT -- Examines magtape. This program is
interactive and will print out a list of possible commands that can be executed if help if typed
once the program has been entered.
Usage: XMT
a ZEROTR --ZEROTR zeroes out the contents of the tcp trace buffer, leaving a clean slate for future TCP
protocol tracing. See TRPT for information on
interpreting the TCP protocol trace information.

The 510 lines are implemented with a Signetics SC2681 DUART. The display keyboard interface implemented with a Motorola MC6850.
When both 510 lines are being used, it is possible to have incompatible baud rates due to l.imi.tations of the SC2681 Chip. One 510 l.ine can't have a baud rate from Group A while the other SIO line is set from Group B:

BLT REGISTERS
Refer to the BLT REGISTERS section of CHAPTER 8, DN400,DN420,DN600, for this infornation.
MD commands (DC, Ie) are used to turn data and instruction caches on and off. Machine must be in physical mode to toggle the instruction cache. Data cache is not controllable from CPIO. Sysboot (when running in CPU) turns both caches on.
CPU CONTROL REGISTERS
ONx60 is a micro-coded machine with a forward-mapped address translation mechanism (using in-memory page tables). There is no PTT or PFT. Some of the MMU Control Register functions described above are in the Control Panel Registers, while much of the control of the CPU is achieved via the MOVEC instruction. The following control register definitions are of interest:
* 120-13F - Current Region Registers (0-31) 11F - Current ASIO lIE - Current Floating Point ASIO 11D - Purge Translation Buffer. Values defined:
1 => purge VA in Control Register llC 2 => purge ent ire TB 4 => purge half of TB containing VA in l1C
l1C - VA used in TB purge 119 - Address Translation and Data Cache
Bit 0 Enable/Disable Address Translation Bit 1 : Enable/Disable Data Cache Bit 7 : Domain Bit
113 - Read Hardware and Microcode Revision Levels (Requires Micro Exec)
* These registers/functions are directly supported by the PROM.

MEMORY CONTROL/STATUS REGISTERS (MeSR)
There are 64 possible memory control regi:ster addresses, beginning at [FC02 FFF9002]. Within each range of $100 addresses, only one board may respond, but owing to the variety of boards supported ('old', 'new', interleaved, non-interleaved), a board
may respond at anyone of 8 addresses within that range (at intervals of $20). Also boards do not have to respond at contiguous ranges. There can be at most 4 memory boards.
Refer to Chapter 8, DN400,DN420,DN600, for control and status format.

SERIAL I/Q INTERFACE
510 page at ( 8400 I FFFBOO ]
DNx60 uses two SC681 chips providing four 510 lines, with control at FFFBOIO. The first line (make B at FFFBOOO) is used for the display keyboard.
Due to limitations of the SC2681 chip, when both 510
lines of a chip are being used, it is possible to have incompatible baud rates. One 510 line can't have a baud rate from Group A while the other 510
line is set from Group B:
=r.=1! 50 75
7200 150 2000 19.2K
Lines 0 (the keyboard, which runs at 1200 baud) and 1 are paired on one chip, and lines 2 and 3 are on the other Chip.
Refer to the SERIAL I/O INTERFACE section of CHAPTER 7, DN300,DN320, for more information.

The DMA chips support only l6-bit addressing, but the system supports 24 bits of physical address. To supply the extra bits of addressing required, 8 one-byte page registers are provided. Each byte is loaded with the high 8 physical address bits for its corresponding DMA channel. Note that DMA can operate on a maximum of 1024 bytes (each channel has only ONE page register).
Addresses of the DMA page registers (note the non-order) :

RING [ 5] DOO-SlCOD S9CDQ-59cOQ ! 3FF6800-3FF8400 J
The DN3000 ring board has an 8K WORD buffer for xmitting/rcving msgs. There is room for 7 rev msg buffers (each lk bytes of
header and lk bytes of data) and 1 xmit msg buffer of the same
size. In the OS, msgs to the network protocol gate array for initialization use the xmit buffer. There is only one read/write
port to the buffer (RAM_DATA) and one address register
(RAM_ADDR). The buffer is read or written by setting the ram_addr and doing sequential word reads/writes to the ram_data port. After setting ram_addr, the first word read should be
discarded.

RCV_PKT_CNT [+802J XMIT_PKT_CNT [+C02J
RCV_MAX_CNT [+804] BAD_PKT_CNT [+C04]
are implemented with Intel 8254 Chips.
To load values into counters, first load CNT_Cx_CNTR with: $3000 before loading rcv hdr cnt $7000 before loading rcv:::':pkt:::':cnt $8000 before loading rcv_max_cnt
The counters are then written with successive word accesses: Isb in high byte of word msb in high byte of word
To read values from counters, first load CNT_Cx_CNTR with: $C200 before reading rcv_hdr_cnt $C400 before reading rcv pkt cnt $C800 before reading rcv:::':max':cnt $CEOO to prepare to read all three
The counters are then read with successive word accesses: status in high byte of word Isb in high byte of word msb in high byte of word
