INVLPG question

INVLPG question

[Xin Tong]

Hello

   When a process has a page fault and Linux swaps out a page from
another process and give it to the page-faulting process. Typically a
INVLPG is used to invalidate entries  in the TLB. I would like to know
whether INVLPG is global ( i.e. across all cores )?

Thanks

Xin

Last I looked the 8086 didn't have a TLB, or page faults of any
description, and I'm pretty sure that nobody's built a multicore
8086-based machine, so I suspect you might have the wrong mailing list.

You may have better luck here:
