Routine Description:
|
||
|
||
This function sets the enables that define which machine check
|
||
errors will be signaled by the processor.
|
||
|
||
N.B. - The system has the capability to ignore all machine checks
|
||
by indicating DisableMachineChecks = TRUE. This is intended
|
||
for debugging purposes on broken hardware. If you disable
|
||
this you will get no machine check no matter what error the
|
||
system/processor detects. Consider the consequences.
|
||
|
||
Arguments:
|
||
|
||
DisableMachineChecks - Supplies a boolean which indicates if all
|
||
machine checks should be disabled and not
|
||
reported. (see note above).
|
||
|
||
DisableProcessorCorrectables - Supplies a boolean which indicates if
|
||
processor correctable error reporting
|
||
should be disabled.
|
||
DisableSystemCorrectables - Supplies a boolean which indicates if
|
||
system correctable error reporting
|
||
should be disabled.

Routine Description:

|

This function fields machine check for 21064-based machines with

parity memory protection.
|
||
|
||
Arguments:
|
||
|
||
ExceptionRecord - Supplies a pointer to the exception record for the

machine check. Included in the exception information

is the pointer to the logout frame.

ExceptionFrame - Supplies a pointer to the kernel exception frame.

TrapFrame - Supplies a pointer to the kernel trap frame.

Return Value:
|

|

A value of TRUE is returned if the machine check has been

handled by the HAL. If it has been handled then execution may

resume at the faulting address. Otherwise, a value of FALSE

is returned.
