Subject: [PATCH v3 26/35] OvmfPkg/XenPlatformPei: Ignore missing PCI Host Bridge on Xen PVH
Date: Thu, 4 Jul 2019 15:42:24 +0100	[thread overview]
Message-ID: <20190704144233.27968-27-anthony.perard@citrix.com> (raw)
In-Reply-To: <20190704144233.27968-1-anthony.perard@citrix.com>

When the device ID of the host bridge is unknown, check if we are
running as a PVH guest as there is no PCI bus in that case.

Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=1689
Signed-off-by: Anthony PERARD <anthony.perard@citrix.com>
---

Notes:
    v3:
    - Remove use of XEN_PVH_PCI_HOST_BRIDGE_DEVICE_ID, and simply don't set
      PcdOvmfHostBridgePciDevId.
    
    v2:
    - Use new XEN_PVH_PCI_HOST_BRIDGE_DEVICE_ID macro
