[PATCH backport to v5.4] EDAC/{i7core,sb,pnd2,skx}: Fix error event severity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



commit 45bc6098a3e279d8e391d22428396687562797e2 upstream

IA32_MCG_STATUS.RIPV indicates whether the return RIP value pushed onto
the stack as part of machine check delivery is valid or not.

Various drivers copied a code fragment that uses the RIPV bit to
determine the severity of the error as either HW_EVENT_ERR_UNCORRECTED
or HW_EVENT_ERR_FATAL, but this check is reversed (marking errors where
RIPV is set as "FATAL").

Reverse the tests so that the error is marked fatal when RIPV is not set.
