Reply-To: sharada@in.ibm.com List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Kexec support involves kernel level support per architecture and a user space kexec-tools. Generic kexec kernel support for ppc (ppc32/GameCube) was added sometime back by Albert Herranz, and I think they got included in 2.6.10-mm1 as per: http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10/2.6.10-mm1/broken-out/ Albert's code was also posted on this site: http://www.gc-linux.org/down/isobel/kexec/ ppc64 kexec kernel support was added recently (2.6.12-rc4-mm1) Eric's site can be used for downloading the kexec-tools. You may want to cross post kexec discussion mails to fastboot@osdl.org, as that is the primary list where all kexec discussions happen. Hope this helps Thanks and Regards, Sharada On Thu, Oct 20, 2005 at 11:03:52PM -0600, Christopher Friesen wrote: > > I've been asked to look at kexec for ppc on 2.6.10.
