Subject: intel_i830_chipset_flush(): local clflush() vs. global wbinvd()
Date: Mon, 26 Apr 2010 10:26:52 +0100	[thread overview]
Message-ID: <4BD5787C020000780003C1DB@vpn.id2.novell.com> (raw)

Eric, Brice,

what is the point of issuing wbinvd() on all CPUs here if clflush isn't
available, but using clflush() (if available) only on the current CPU?

Thanks, Jan
