From 042c1461fb777e583e5de48edf9326e47ee5595f Mon Sep 17 00:00:00 2001 From: Sven Schnelle Date: Sun, 17 Jun 2012 10:32:55 +0200 Subject: Use broadcast SIPI to startup siblings The current code for initializing AP cpus has several shortcomings: - it assumes APIC IDs are sequential - it uses only the BSP for determining the AP count, which is bad if there's more than one physical CPU, and CPUs are of different type Note that the new code call cpu->ops->init() in parallel, and therefore some CPU code needs to be changed to address that. One example are old Intel HT enabled CPUs which can't do microcode update in parallel.
