I found that in mpcore there are 4 cores, the cpu0 boots first, and the others wait in the WFI(wait for interrupt) state. as far as i know it is the boot monitor set these cores into WFI state. I just wonder what happens after these cores get the interrupt. they jump to the kernel? or sth eles? if they jump to the kernel, to what address? and these jump instructions are in the boot monitor? sorry for so many questions.... thanks a lot. 2007/8/22, Alan Cox : > On Wed, 22 Aug 2007 16:53:41 +0200 > "Xu Yang" wrote: > > > Hi everyone, > > > > I am just wondering how is the boot process of the multicore system exactly. > > let's say there are 4 cores , what is the booting sequence? and how > > does linux realise the booting process? > > For PC type systems read the Intel MP 1.4 specification, available on the > intel developer web site > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
