Subject: suspend-to-ram on athlons
Date: Fri, 7 Dec 2001 22:01:30 +0100 [thread overview]
Message-ID: <20011207220130.A9253@elf.ucw.cz> (raw)
Hi!
suspend-to-ram was not working on athlons... Now I found the reason...
We wrote some data to memory, and then told hw to powerdown everything
but memory.
But somehow data were not in memory.
So I added mdelay(1000) and printk().
Data were still not in memory.
So I added wbinvd().
Yep, that helped. That means that athlons happily write-back-cache
data for 1 second.... Ouch.
Okay, I just did not expect *that* kind of trick being played at me.
Pavel
