6.7.4 Machine Checks/Interrupts
The exceptions that result from hardware system errors are called machine checks/interrupts.
They occur when a system error is detected during the processing of a data request.
During the error-handling process, errors are first handled by the appropriate PALcode error
routine and then by the associated operating system error handler. PALcode transfers control to
the operating system through the system control block (SCB) vector. The SCB vectors pertain
to Tru64 UNIX and OpenVMS systems only.
The following types of machine checks/interrupts are related to system events.
•
CPU Correctable Error (630)
•
CPU Uncorrectable Error (670)
•
System Correctable Error (620)
•
System Uncorrectable Error (660)
•
System Environmental Error (680)
6.7.4.1 CPU Correctable Errors (SCB: 630)
CPU correctable errors are generic Alpha 21264 microprocessor correctable errors. The
following EV6-detected conditions cause PALcode to invoke the operating system 630 error
handler:
Error Code
(Hex) Machine Check
Type
Error Description
86 Correctable B-cache probe hit single-bit ECC error
9E Correctable D-cache tag parity error on issue
86 Correctable I-cache tag or data parity error
86 Correctable D-cache victim single-bit ECC error
86 Correctable B-cache single-bit ECC fill error to I-stream or D-stream
86 Correctable Memory single-bit ECC fill error to I-stream or D-stream
6.7.4.2 CPU Uncorrectable Error (SCB: 670)
CPU uncorrectable errors are fatal microprocessor machine check errors that result in a system
crash. The error conditions are:
Error Code
(Hex) Machine Check
Type
Error Description
8E CPU uncorrect PAL detected bugcheck error
90 CPU uncorrect Operating system detected bugcheck error
98 CPU uncorrect EV6 detected second D-cache store EEC error
98 CPU uncorrect EV6 detected D-cache tag parity error in pipeline 0 or 1
98 CPU uncorrect EV6 detected duplicate d-cache tag parity error
98 CPU uncorrect EV6 detected double-bit ECC memory fill error
98 CPU uncorrect EV6 detected double-bit probe hit EEC error
98 CPU uncorrect EV6 detected B-cache tag parity error
