X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 02 Jan 2004 16:08:50 -0000 Hi all, With late ULE you can watch a process hopping between CPUs. This seems to the base functionality for CPU hot swapping. One would need (apart from a Motherboard that's able to that ;-)) some control over CPUs now, like disabling a physical CPU during runtime (which could also be done automatically on certain filure onditions). Is there any work in progress in this direction? Would be a very neat feature for high availability systems. - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
