| Thread-topic: | [Xen-devel] [PATCH] [VTD] Add checking on return value of init_vtd_hw() |
This patch adds checking on return value of init_vtd_hw(). This ensures correct actions will be taken if init_vtd_hw() fails. Especially, when 'iommu=force' is used, Xen should be not booted if init_vtd_hw() fails. Signed-off-by: Weidong Han <weidong.han@xxxxxxxxx>
