The VAX Architectural and Floating Point Instruction
FExercisers are used to verify the inteqrity of the FP750 option.
These instruction exercisers will run under the Diagnostic Suvervisor
stand=alone or on-line, but to properly test the #P7S0 they should
be run stand-alone., (In on=line mode, tney cannot disable and
enable the FP750). The enhanced DP¥ micro diagnostic is used to
verity the logaic wnich i{nterfaces the FP750 from the DPM module
of

the

11/750

processor,

Version V07,2 or greater of the ECKAR DPM =micro diagnostic will
verify some of the CPU-FPA interface logic., Verification of this

interface logic, w#which is resident in the DPM module of the CPU
and is not activated until the FPA i{s enabled, is tested under
test D2-DC of this diagnostic. These test are listed below:

Default: In the default mode the program sizes the system passing
the configuration information on to the Diagnostic Supervisor. After
the execution of the program this information may be seen by the
operator by typing SHOw DEVICE after the DS> prompt.

ALWAYS VERIFY this information when using this mode since the program
makes educated guesses reguarding some necessary information.

Control Status Registers and vectors may be configured incorrectly
for a particular system,

3.2 Manual: The Manual option may be executed by typing the following
command after the DS> prompt: RUN EVSBA.EXE/SECTION:MAJUAL
This causes the program to give the following prompt: COMMAND?
Legal responses to thls prompt are: ATTACH, CHANGE, EXIT, HKELP,

NOTICE WHAT HAFPPENED TO THE PC AND PC+4... THE PC HAS REEN RUMFED
TO 105 WHICH TELLS THE PRK CHIF THAT WE HAVE USED ALL THE DATA IN
XBO.
A FREFETCH CYCLE WILL OCCUR USING THE PC+4 AS OUR AIDRESS TO
FETCH DATA FROM MAIN MEMORY.
IF WE SEND THE ADNDRESS OF 109 OVER THE
CMI WE WILL GET BACK THE LONGWORD ADDRESS CONTAINING 109.
THIS5 IS
~ DUE TO THE FACT THAT THE CMI IGNORES RITS 0 AND 1 OF THE ADINNRESS
THUS GIVING US A LONGWORD ADLDRESS OF 108 WHICH IS EXACTLY WHAT WE
WANT.

EXECUTION OF THE NEW INSTRUCTION TAKES PLACE SIMUTANIOUSLY WITH
THE PREFETCHs BUT NOTICE WHAT INSTRUCTION WE ARE USING...
IT IS A HALT INSTRUCTION. WE KNOW THAT A HALT INSTRUCTION HAS
NO OPERANDS ONLY AN OPCODE, THEREFORE SOMETHING MUST BE DONE TO
PREVENT THE IRD CHIP FROM EVALUATING THE SECOND BYTE AS A 1st OFERANI
SPECIFIER. WHAT HAPPENS IS WHEN THE IRD1 ROMS DECODE THE HALT
OPCODE, (OR ANY ONE BYTE INSTRUCTION) A SIGNAL NAMED °"ROM 0S INHIEIT®
WHERE
IS OUTPUTED FROM THE ROM ITSELF AND SENT TO THE MSQ AND SAC CHIFS THE
FREVENT
WILL
WHICH
A*®
IT DISABLES ANOTHER SIGNAL CALLED °LOD OSR
UPDATING OF THE OSR COUNTER. THE SAME SIGNAL TELLS THE SAC CHIF TO

WHICH WILL
TELL THE PHR CHIP NOT TO GENERATE THE SIGNAL °*IRD LOD RNUM®
THE °*LOD' OSR A°
PREVENT THE SFA CHIP FROM LOOKING AT RNUMs AND FINNALY
SIGNAL TELLS THE IRD CHIF NOT TO DECODE THE DATA ON THE OSR SECTION
OF XB DECODE AS IT IS NOT REALLY AN OFERAND.

THE HALT MICROCODE FLOW WILL NOW TEST THE CURRENT MODE TO SEE IF WE
ARE IN KERNAL MODE AS YOU MUST EBE TO HALT THE CPU.

ASSUMING THAT WE ARE IN KERNAL MODE, THE MICROCODE ROUTINE WILL ...
1).
2y,
2).
4).,

SET UP A HALT CODE OF 06 IN A TEMFORARY REGISTER
ADD 1 TO THE CURRENT PC GIVING US PC=106 AND FC+4=10A
VARIOUS OTHER TASKS REQRUIRED TO SHUTLIOWN THE CFU
AND FINALLY SENDN THE FC TO THE FRINT ROUTINE

151

THE MICROCODE PRINT ROUTINE WILL ALWAYS SUBRTRACT 2 FROM ANY GIVEN
PC BEFORE

ACTUALLY

PC=

SENDING

106

IT TO

00000104

THE CONSOLE.

104

THIS LEAVES US AT A PC OF 104 WHICH
OPCODE OF THE HALT INSTRUCTION.

- THE REASON FOR THIS
>>>
AND

CONTINUE

ONE BYTE AHEAD

IS BECAUSE NOW WE CAN

SIMPLY

THE

ACTUAL

TYPE...

C
ON

ONE FINAL NOTE:

WITH

THE

OPCODE FOLLOWING

THE

HALT

INSTRUCTION.

DURING EXECUTION OF MACRO INSTRUCTIONSs IF ANY
INSTRUCTION BLOWS UP AFTER BEING DECODED ON AN

GIVEN
IRD1,

THE PC WOULD HAVE ALREADY BEEN UPDATED BY 2...
SO0 THE PRINT ROUTINE CALLED IF WE WERE TO HALT THE
CPU, WOULD SUBTRACT 2 FROM THE PC GIVING US THE

CORRECT OPCODE ADDRESS OF THE FAILING

INSTRUCTION.

THIS ALSO CLARIFIES WHY WE HAVE TO AID 2 TO A
MICRO-VERIFY ERROR HALT TO GET THE CORRECT FAILURE
CODE.
THE MICRO-VERIFY ROUTINE IS RESIDENT IN ZCS
ROM AND IS NOT A MACFO PROGRAM AT ALL! THUS IT DOES
NOT UPDATE THE PC IN ANY WAY» BUT IT STILL USES THE
SAME PRINT ROUTINE FOR THE ERROR DISFLAY.

YOU’VE GOT THAT DOWN???

11/750 MACHINE CHECK INTERFRETATION

TO HELFP ALIVIATE ANY PROEBLEMS HAVING TO DO WITH MACHINE CHECKS
IN THE 11/750 BELOW IS AN EXPLANATION OF WHY AND HOW THEY OCCUR

ALONG WITH AN EXPLANATION OF HOW TO READ THE MACHINE CHECK LOGOUT.
A MACHINE CHECK IS A UTRAF TO LOCATION 28 IN THE MICROCODE. THIS
1S CAUSED ONLY BY TWO CONDITIONS WITHIN THE LOGIC OF THE UTR CHIF.
THESE CONDITIONS ARE AS FOLLOWSS

1. TRANSLATION BUFFER PARITIY ERRORS IN DATA OR TAG
2.

BUS ERROR

THIS SOUNDS EASY BUT WHAT CAN CAUSE A BUS ERROR IS THE PROBLEM.
PLEASE LOOK AT THE FOLLOWING CHART AND READ THE EXFLANATION RELOW

WE WILL USE THE AROVE CHART TO INTERPERT THE MACHINE CHECKN LOGOUT
THAT IS OM FAGE 25 IN THE VAX 11/7S50 DIIAGNOSTIC MINI REFERENCE GUIDE.
ATTACHED TO THIS SHEET IS A COPY OF THE LOGOUT ANI' A BREAKQUT OF
THE NEEDED REGISTERS IF YOU HAVE NO MINI REFERENCE GUIDE.
WE NEED TO CORRECT ONE AREA OF THE LOGOUT IN THE MINI REF. GUILDE

BEFORE WE GO ON. AT LOCATION (SFP)+28 IT SHOULD READI MACHINE CHECK
ERROR SUMMARY REGISTER AND NOT MEMORY CONTROL REGISTER.

—_—

154
ALL RIGHT WE ARE OFF!!!! WHAT YOU SEE IN THE LOGOUT IS WHAT IS FUSHED
ONTO THE STACK WHEN A MACHINE CHECK OCCURS WHILE NORMAL RUNNING OF
VUMS *AFTER® THE VECTOR ADDRESS IS BROUGHT
IN IN FROM SCBE+4 AND THE
VECTOR RITS O AND 1 ARE CHECKED. WE WILL ATTACK THE STACK DUMF FROM
TWO

AREAS?

LOCATION

INFORMATION RELATING TO LOCATION OF FAULT (PC ETC)

CAUSE OF THE FAULT.

AT (SP)+8 IS THE VIRTUAL ADDRESS REGISTER. THIS
REGISTER IS USED TO FETCH THE OPERAND DATA NEEDED
BY THE INSTRUCTION. SO IT CONTAINS THE OPERAND
ADDRESS IF THE MACHINE CHECX OCCURRED WHILE FETCHING
OPERAND

DATA.

(SP)Y+C

THE PC AT THE TIME OF THE

EXCEFTION.

THIS MAY BE USED WITH (SP)+2C WHICH IS THE ADDRESS OF
THE OPCODE OF THE FAILING

INSTRUCTION.

EX:

IF YOU

ARE PREFETCHING AND USE AN INSTRUCTION AT ADDRESS 1000
AND THAT INSTRUCTION HAS S OPERAND SPECIFIERS THE ADDRESS OF
THE OPCODE +2 IS STORED IN THE PC BACKUP REGISTER UNTIL
THE NEXT OPCODE IS USED.(IRD1 TIME) AS YOU USE THE S
OPERANDS IN THE INSTRUCTION THE PC (NOT PC BACKUP) IS
INCREMENTED TO KEEP TRACK OF EXECUTION BUFFER USAGE.
SO0 IF WE HAVE A MACHINE CHECK INVOLVED WITH EXECUTION
BUFFER DATA» WE HAVE PUSHED ONTO THE STACK THE ACTUAL
PC (SP+C) AND THE OPCODE OF THE INSTRUCTION (SF+2C).
AT
CAUSE?

(SP)+30 WE HAVE THE STANDARD PSL.

WE SHOULD FIRST LOOK AT THE SUMMARY FARAMETER COIE
AT (SP)+4. GENERALLY SFEAKING YOU WILL ONLY HAVE
NUMBERS 15256 OR 7. 156 AND 7 ARE BASICALLY THE SAME THING.
THESE MEAN A CONTROL STORE PARITY ERROR OCCURRED OR SOMEHOW
THE MACHINE WAS SENT TO AN UNUSED IRD OR UNKNOWN ROM
LOCATION., THIS COULD HAPPEN FOR A FEW REASONSsy OF WHICH
THE MOST LOGICAL IS THAT YOU HAVE A BAD CONTROL STORE»
EAD MICROSEQUENCER ON THE DPM OR A BADI IRD DECODRE ON
THE

DPM.

155

THE MOST COMMON AND HARDEST TO FIGURE OUT IS THE COLE
OF 2. THIS RELATES TO MEMORY ERROR»TR PARITY TIMEOUT ETC.
YOU LIKE THAT ETC. DO YOU. WELL LETS TARKE THE CONFUSION
OUT OF THE STATEMENT. IF YOU EVER SEE A 2 FOR A SUMMARY
IS THE
PARAMETER CODE THE FIRST THING YOU SHOULD LOOK AT CAN
YOU
8.
MACHINE CHECK ERROR SUMMARY REGISTER? (SF)+2

RELATE THIS REGISTER(MCESR) TO THE AROVE CHART BECAUSE IT
WILL TELL YOU WHAT CAUSED YOU TO GET TO UCODE ADDRESS 28.
FIND THE BREAKOUT OF THE MCESR (PAGE 28 IN MINI REF.GUIDE)
AND YOU WILL SEE A FOUR BIT REGISTER. LET US MAKE THE
NEEDED CHANGE. THERE IS NO LONGER AN UNALIGNED UNIEUS
REFERENCE THAT CAUSES A MACHINE CHECK, SO CROSS IT OFF.
BIT O WILL TELL YOU IF THE MACHINE CHECK OCCURED WHILE
DOING A PREFETCH OR OPERAND FETCH.(THIS MAY HELF YOU TO
FIGURE ON USING THE VA OR PC FOR LOCATION)

HAPPENI&G
IF BIT 0=0 THEN AN OPERAND FETCH WAS
INSTRUCTION CAUSED IT.
IF BIT O0=1 THEN A PREFETCH OF AN

BITS 2 AND 3 WILL TELL YOU IF IT WAS A TE ERROR OR EBUS ERROR
AS AN EXAMFLE WE WILL USE THE TB ERROR FIRST.

TB PARITY ERROR WHILE FETCHING AN OPERAND WOULD CAUSE
THE REGISTER TO LOOK LIKE THIS WHEN PUSHEDl ON THE STACK
00000004 BIT 2 SET AND O CLEAR.

IF A TR ERROR OCURRED WHILE PREFETCHING IT WOULD RE

AS FOLLOUWS?

00000005 RIT 2 SET AND O SET.

EITHER WAY IF IT IS A TB ERROR YOU SHOULI' THEN LOOK
AT(SF)+1C OR THE TRANSLATION GROUF REGISTER. THIS WILL
TELL YOU WHICH GROUF (0 OR 1) AND IF IT WAS A TAG OR
DATA

ERROR.

YOU MAY ALSO LOOK AT (SF)+14 WHICH IS THE SAVED MOLDE
REGISTER. THIS WILL TELL YOU THE PROCESSOR ACCESS MOIE
ANDI MEMORY MANAGEMENT STATES DURING THE LAST MICROCODE
REFERENCE TO MEMORY.

FROM THIS YOU SHOULD KNOW WHAT CAUSED THE MACHINE CHECK AND
THE LOCATION.

LET US RETURN TO THE MCESR AND ASSUME IT LOOKRED LIKE THISS
00000008 BIT 3 SET O CLEAR

THIS WOULD MEAN A BUS ERROR HAFFENED DURING AN OFERAND
FETCH.

IF YOU LOOK AT THE CHART YOU WILL FIND THERE ARE TWO THINGS
THAT CAN CAUSE A BUS ERROR. TO FIND OUT WHICH ONE IT WAS
LOOK AT (SP)+24 THE BUS ERROR REGISTER. THE BUS ERROR

REGISTER IS A FOUR BIT REGISTER IN THE MEMORY INTERCONNECT
MODULE SLOT THREE.(NOT THE MEMORY CONTROLLER) THE EXAMPLE
WE WILL USE FIRST IS UNCORECTABLE DATA CAUSED THE BUS ERROR.
THE BUS ERROR REG. WOULD LOOK LIKE THIS#
00000004

THIS SAYS UNCORECTABLE DATA CAUSED THE ERROR:»

THERE WERE NO LOST ERRORS(RECEIVED AN OTHER ERROR
BEFORE THE LAST ONE WAS CLEARED)

111 ICORRECTED READ DATA DID NOT OCCUR. CORRECTED
READ DATA CAUSES AN INTERRUPT NOT A MACHINE CHECK!!!

IF YOU LOOK AT THE CHART YOU WILL FIND THAT UNCORRECTABLE

DATA CAN BE CAUSED BY TWO THINGS#
1.

CACHE PARITY ERROR

UNCORECTAELE DATA FROM THE CMI

TO DETERMINE WHICH OF THESE CAUSED THE BUS ERROR LOOK
AT (SP)>+20 WHICH IS THE CACHE ERROR REGISTER. THIS
REGISTER CONTAINS INFORMATION ON THE DATA CACHE. IT IS
A FOUR BIT REGISTER ON THE MIC MODULE THAT WILL TELL YOU
IF THE LAST REFERENCE WAS A HIT; LOST ERROR AGAIN AS EREFORE
AND IF YOU HAD A CACHE FARITY ERROR. IF THERE WAS NO CACHE
PARITY ERROR SET IN THE REGISTER THEN THE EUS ERROR WAS
CAUSED RY THE UNCORRECTARBLE DATA FROM THE CMI.

157
S0; CONTINUING RIGHT ON LET US ASSUME THAT THE BUS ERROR
THE
WAS CAUSED T BY A NON EXISTANT MEMORY. AS YOU CAN SEE BY THE
AT
LOOK
LETS
FIRST
NXM.
CAUSE
CAN
THINGS
CHART THAT TWO
BUS ERROR REGISTER. IT EQUALS?

00000008 BIT 3 SET = NXM

THEN WE WOULD LOOK AT THE READ LOCK TIME OUT REGISTER (RLTQ)
THIS IS A ONE BIT REGISTER THAT IF BIT 0 IS SET A READ' LOCK
TIME OUT CAUSED THE NXM. WHAT IS A READ LOCK TIME OUT? GooD
A READ

NXM
TES
THEN THE CMK CHIF GENERA
CAUSE A MACHINE CHECK. IF BIT O IS CLEAR IN THIS REGISTER ANL
THE BUS ERROR REGISTER SAYS A NXM CAUSED THE MACHINE CHECK
THEN IT WAS CAUSED RY NXM ON THE CMI.

THE ONLY THING THAT WAS PUSHED ONTO THE STACK THAT UWE
HAVE NOT TALKED ABOUT IS (SP)+10s, THE MEMORY DATA REGISTER
(MDR). THIS WILL CONTAIN THE LAST DATA FETCHED FROM CACHE

OR MAIN MEMORY.

HOPEFULLY THIS EXPANATIONs CHART AND HANLOUT WILL
CLEAR UP SOME MISCONCEPTIONS CONCERNING THE 11/7350

The Signal Array contains more interesting information about the
1gchecx,
The format of the Signal Array varies for different Bugchecks.
1@ Exception Code identifies what xind of error led to the Bugchecx,
1he
rception Code indicates such errors as Access Violation, Opcode Reserved
DEC, etc.,
Ffollowing the Exception Code are optional arguments.
These
.guments will vary in numoer and meaning for different Bugchecks.,
Next on
the stack is the PC of tne instruction that would have been executed next,

occurred.

Once you have located the Exception Code
enter the following on a running VAX/VMS system:

within the Signal Array,

-7

$ 8TT<Er>

S EXIT $X<exception code><cr>

’

For access violations the EXCEPTION CODE is 0000000C.
EXAMPLE?
$§ 8TT<ce>

%SYSTEH-F-ACCVIO..access violation, reason mask=00,
virtual address=0000000C,

Now that you know wnat the Exception Coce means, you can look up
a short explanation in tne VAX/VMS System Messages and Recovery Procedures
Manual.
