From 575186163cab83b73317dd56e6c0f708b904afb8 Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Thu, 31 Oct 2019 15:09:04 +0000 Subject: [PATCH] docs/misc: xen-command-line: Remove wrong statement from serrors=diverse When serrors=diverse is selected by the user, we will only synchronize the pending SErrors on entry to hypervisor from guest context and exit from guest to hypervisor context. We don't need synchronize SErrors between guest context switch as they would be categorized to Hypervisor generated SErrors in any case.
