From 57550a28b8d4b2e7a983bc10406f0ad81e491f98 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Sat, 23 Nov 2019 06:24:41 +0200 Subject: cpu/qemu-x86: Drop select SMP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With MAX_CPUS==1, this has the effect of removing spinlock implementation. But since is_smp_boot() evaluates false and SMM uses separate smi_semaphore, there is no concurrency to protect against with a spinlock.
