From: Andi Kleen Date: Tue, 21 Aug 2007 12:42:40 +0000 (+0200) Subject: i386: Mark NUMA support experimental X-Git-Tag: v2.6.23-rc4~99 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=36ce1514117b92b7372e1b041ccc686855454d33;p=linux-2.6 i386: Mark NUMA support experimental I did some testing and found quite a lot of problems (doesn't boot at all on non NUMA and misassigns cores on Opteron systems). Mark it as experimental and warn against its use for now. It's still default y for SUMMIT/NUMAQ because it'll presumably work on these systems.
