From 69edb0f37a52053978de65a81241ef171a6f2396 Mon Sep 17 00:00:00 2001 From: Xiaoyao Li Date: Sat, 12 Oct 2019 10:47:48 +0800 Subject: [PATCH] target/i386: Add Snowridge-v2 (no MPX) CPU model Add new version of Snowridge CPU model that removes MPX feature. MPX support is being phased out by Intel. GCC has dropped it, Linux kernel and KVM are also going to do that in the future.
