SUBTTL HISTORICAL NOTES
REPEAT 0, <
;THE COMMON SUBPROGRAM CONSISTS OF 6 FILES ASSEMBLED TOGETHER AS ONE SUBPROGRAM
1. F.MAC -- FEATURE TESTS (OUTPUT OF MONGEN).
2. S.MAC -- THE USUAL SYSTEM SYMBOL DEFINITIONS ASSEMBLED WITH
EVERY MONITOR SUBPROGRAM
3. SYSCNF.MAC -- SYSTEM CONFIGURATION
4. COMMON.MAC - THE REST OF THIS PROGRAM WHICH IS THE SAME SOURCE FOR
ALL CONFIGURATIONS. HOWEVER, THE ASSEMBLIES ARE CONDITIONED BY
SYMBOLS AND MACROS DEFINED IN 2.
THE FOLLOWING SYMBOLS AND TABLES ARE GENERATED BELOW:
A. MONITOR STARTUP LOCATIONS (400-407), HENCE LOAD THIS FIRST.
B. JOB TABLES - LENGTH DEPENDENT ON MAXIMUM NUMBER OF JOBS ALLOWED
C. ALL VARIABLE STORAGE NOT ASSOCIATED WITH A PARTICULAR DEVICE
D. COMMON SUBROUTETURNS
E. COMMON BYTE POINTERS
F. TABLE OF SERVICE ROUTINE INTERRUPT LOCS TO BE LINKED BY ONCE ONLY CODE
G. TABLE OF DEVICE DATA BLOCK ADDRESSES AND NUMBER TO BE USED BY ONCE TO
LINK THEM TOGETHER AND GENERATE MULTIPLE COPIES.
H. ASSIGNMENT OF PI CHANNELS
I. PI CHANNEL SAVE AND RESTORE ROUTINES
J. UUO TRAP LOCATIONS 40/41, 60/61
K. APR INTERRUPT LOCATIONS CPU0,1, KA10/KI10
L. SYSTEM CRASH STOP CONI'S.
NOTE: SEE COMDEV FOR DEVICE DEPENDENT CODE, DATA, AND SYMBOLS
LEVEL D DISK SERVICE PARAMETERS:
ALL SYMBOLS ANAS ONATIONS ARE IN A SEPARATE FILE CALLED
COMMOD.MAC WHICH IS ALSO ASSEMBLED WITH S AND CONFIG (BUT NOT WITH FEATURS FILES).
THE SEPARATE FILE IS FOR TWO REASONS: 1. ANTICIPATING MULTIPROCESSING SYSTEMS WHICH SHARE DISKS AND 1 16K MEMORY
(THE DATA MUST BE IN THE COMMON MEMORY)
2. ELIMINATE THE NEED TO ASSEMBLE COMMOD IF NOT A DISK SYSTEM
(COMMOD.MAC TAKES LOTS OF CORE FOR ITS COMPLICATED MACROS)

SUBTTL CONVERT MONGEN SYMBOLS
;THIS SECTION CONVERTS NEW MONGEN SYMBOLS TO OLD MONGEN SYMBOLS
;SO THAT THE REST OF COMMON AND MONITOR CAN STILL USE THE OLD
;SYMBOLS. THIS WAS DONE RATHER THAN CONVERTING ALL OF THE
;MONITOR TO NEW SYMBOLS FOR TWO REASONS:
; 1. IT IS EASIER AND FASTER AND LESS LIKELY TO INTRODUCE BUGS, AND
; 2. IT ALLOWS CUSTOMERS TO USE OLD MONGEN WITH A MINIMUM
;OF TROUBLE: ONLY A FEW EXTRA SYMBOLS MUST BE DEFINED.
;THE MONITOR WILL PROBABLY BE CONVERTED TO THE NEW MONGEN SYMBOLS
;AFTER THE 5.04 RELEASE. THE ORDER HERE PARALLELS THE OLD
;MONGEN ORDER.

SUBTTL CPU DATA BLOCK(S):
REPEAT 0,<
EACH CPU HAS ITS OWN DATA BLOCK, KNOWN AS A CDB. ALL .CP??? SYMBOLS ARE
DEFINED RELATIVE TO THE (MAPPED) CDB, .CN??? SYMBOLS ARE ABSOLUTE LOCATIONS.
A FEW LOCATIONS ARE REALLY SYSTEM PARAMETERS (EG. CORTAL), RATHER THAN CPU
PARAMETERS. HOWEVER, THEY WERE IN THE MIDDLE OF A GETTAB (NSWTBL) AND SO
COULD NOT BE SEPARATED OUT WITHOUT INVALIDATING SOME PROGRAMS.
WHEN ADDING CONSTANTS OR VARIABLES TO COMMON, GREAT CARE MUST BE EXERCISED
IN DECIDING WHETHER TO PUT IT IN THE CDB OR IN A SYSTEM DEPENDENT TABLE
(.SYTBL). IF THE CONTENTS COULD EVER BECOME CPU DEPENDENT IN THE FUTURE,
BE SURE TO PUT IT IN THE CDB INSTEAD OF .SYTBL. IF A MISTAKE IS MADE, THE
LOCATION WILL HAVE TO APPEAR IN THE CDBS AS WELL AS .SYTBL IN ORDER TO INSURE
COMPATIBLITY.

;DATA BASE TO LIMIT THE NUMBER OF STOPCD'S PER UNIT TIME SO THAT
;WE DON'T KEEP GETTING "CONTINUABLE" STOPCD'S THAT REALLY AREN'T.
;THE DATA BASE CONSISTS OF TWO TABLES, SCCTAB AND SCLTAB. SCCTAB
;IS THE COUNT OF THE NUMBER OF STOPCD'S PROCESSED DURING THE PERIOD
;INDICATED BY THE OFFSET IT THE TABLE. SCLTAB CONTAINS, IN THE
;LEFT HALF, THE PERIOD FOR THIS ENTRY AND, IN THE RIGHT HALF, THE
;LIMIT FOR THE NUMBER OF STOPCD'S DURING THE PERIOD. BOTH TABLES
;MUST BE ORDERED SUCH THAT THE PERIOD OF EACH ENTRY IS MONOTONICALLY
;INCREASING. THE LIMITS FOR EACH PERIOD ARE CHANGABLE VIA THE MONGEN
;DIALOG AND MAY BE CHANGED BY THE CUSTOMER. WHEN A STOPCD IS PROCESSED
;BY DIE, STCLIM INCREMENTS THE COUNTS OF STOPCD'S FOR EACH ENTRY
;AND COMPARES EACH WITH THE LIMIT FOR THE ENTRY. IF A LIMIT HAS BEEN
;EXCEEDED, DIE TURNS THE CONTINUABLE STOPCD INTO A STOP STOPCD. IF
;NO LIMIT HAS BEEN EXCEEDED, STCLIM PUTS IN A CLOCK REQUEST TO CALL
;DECSCC AFTER THE PERIOD OF THE LOWEST ENTRY IN THE TABLE. DECSCC
;DECREMENTS THE COUNT OF STOPCDS FOR THIS ENTRY AND PUTS IN A CLOCK
;REQUEST TO DECREMENT THE NEXT HIGHER COUNT. THIS CONTINUES UNTIL ALL
;HAVE BEEN DECREMENTED. NOTE, THAT SINCE THE CLOCK QUEUE IS USED TO
;DECREMENT THE STOPCD COUNTS, THE PERIOD OF THE LARGEST ENTRY CANNOT
;BE LARGER THAN 2**18-1 TICKS.
