From 26dc4a5bf96bb0ee19a0e446fead1546d5b07dac Mon Sep 17 00:00:00 2001 From: Heiher Date: Wed, 23 Jan 2019 15:34:02 +0800 Subject: [PATCH] i386: hvf: Fix smp boot hangs The machine that with hvf accelerator and smp sometimes boot hangs because all processors are executing instructions at startup, including early I/O emulations. We should just allow the bootstrap processor to initialize the machine and then to wake up slave processors by interrupt.
