From: Shmulik Ladkani Date: Sun, 13 Dec 2015 08:08:29 +0000 (+0200) Subject: vmw_pvscsi: Introduce 'x-old-pci-configuration' backword compatability property X-Git-Tag: v2.6.0-rc0~258^2~37 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=952970b;p=thirdparty%2Fqemu.git vmw_pvscsi: Introduce 'x-old-pci-configuration' backword compatability property Following the previous patches, which introduced various changes in pvscsi's pci configuration space (device subsystem id and revision, msi offset), this patch introduces a boolean property 'x-old-pci-configuration' to pvscsi. Its default value is false, exposing the above changes in the pci config space. Setting 'x-old-pci-configuration' to 'on' preserves the old behavior, which allows migration to older versions.
