Re: [PATCH] Document Linux's memory barriers
From: Stephen Hemminger
Date: Tue Mar 07 2006 - 12:45:21 EST
This has been needed for quite some time but needs some more
additions:
1) Access to i/o mapped memory does not need memory barriers.
2) Explain difference between mb() and barrier().
3) Explain wmb() versus mmiowb()
Give some more examples of correct usage in drivers.
