| Message-ID | <r7Ekx-tv-5@gated-at.bofh.it> |
The Deferred field indicates if we have a Deferred error. Deferred errors indicate errors that hardware could not fix. But it still does not cause any interruption to program flow. So it does not generate any #MC and UC bit in MCx_STATUS is not set. Fixing comment here. No functional change Signed-off-by: Aravind Gopalakrishnan <Aravind.Gopalakrishnan@amd.com> --- arch/x86/include/asm/mce.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/x86/include/asm/mce.h b/arch/x86/include/asm/mce.h index 69f8bda..3b45e36 100644 --- a/arch/x86/include/asm/mce.h +++ b/arch/x86/include/asm/mce.h @@ -40,7 +40,7 @@ #define MCI_STATUS_AR (1ULL<<55) /* Action required */ /* AMD-specific bits */ -#define MCI_STATUS_DEFERRED (1ULL<<44) /* declare an uncorrected error */ +#define MCI_STATUS_DEFERRED (1ULL<<44) /* uncorrected error, deferred exception */ #define MCI_STATUS_POISON (1ULL<<43) /* access poisonous data */ #define MCI_STATUS_TCC (1ULL<<55) /* Task context corrupt */ -- 2.7.0
