Subject: Re: RFC: outb 0x80 in inb_p, outb_p harmful on some modern AMD64 with MCP51 laptops
Date: Tue, 11 Dec 2007 11:40:23 +1030	[thread overview]
Message-ID: <475DE37F.20706@davidnewall.com> (raw)
In-Reply-To: <m3bq8y23de.fsf@maximus.localdomain>

Where did the 8us delay come from?  The documentation and source is 
careful not to say how long the delay is.  Would changing it to, say 
1us, be technically wrong?  Is code that requires 8us correct?
