Hi Aravind,
question: what's the story with MC?_MISC[IntP], is that bit still there?
Because I don't see it in my BKDGs here.
Yep, It exists.
Maybe you are referring to Fam15h M0h BKDG? I think the bit was
introduced only from F15h M30h onwards.
The bit does *not* exist for bank=4, But-
if (bank ==4)
return true;
takes care of that.
The background of the story is
https://lkml.org/lkml/2014/10/7/84
There's this thing we did at the time
f227d4306cf3 ("x86, MCE, AMD: Make APIC LVT thresholding interrupt optional")
which, AFAICR, is about some F15h versions having a counter but *not*
generating a thresholding interrupt. Can you confirm that is still
the case and we can have a counter but no interrupt gets generated on
overflow?
So yes, moving the assignment inside the if condition should work just fine.
I see the patch on your 'ras-for-3.19' branch does not have this, so
I'll make this modification
to the branch before I test it.
Thanks,
-Aravind.
