From 8b4ce83707cb2cff5f6d175ea38f751ac4456096 Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Mon, 7 Sep 2020 15:15:57 +0200 Subject: [PATCH] x86/sev-es: Handle INVD Events Implement a handler for #VC exceptions caused by INVD instructions. Since Linux should never use INVD, just mark it as unsupported.
