Subject: [PATCH 2/3] OvmfPkg/XenSupport: use a correct PCI host bridge aperture for BAR64
Date: Mon, 4 Mar 2019 15:04:07 +0000 [thread overview]
Message-ID: <1551711848-22470-3-git-send-email-igor.druzhinin@citrix.com> (raw)
In-Reply-To: <1551711848-22470-1-git-send-email-igor.druzhinin@citrix.com>
In case BAR64 is placed below 4G choose the correct aperture.
This fixes a failed assertion down the code path.
