From 80b619d5c456c286e58b122690ff254aeca7f12c Mon Sep 17 00:00:00 2001 From: Anthony PERARD Date: Tue, 13 Aug 2019 12:31:01 +0100 Subject: OvmfPkg/XenPlatformPei: Reinit XenHypercallLib The XenPlatformPei needs to make hypercalls, but the XenHypercallLib was initialised before the HyperPage was ready. Now that XenPlatformPei has initialised the HyperPage, reinitialise the XenHypercallLib.
