Subject: [GIT PULL] Thunderbolt changes for v4.21
Date: Mon, 10 Dec 2018 12:23:03 +0200 [thread overview]
Message-ID: <20181210102303.GC2469@lahna.fi.intel.com> (raw)
Hi Greg,
This includes automatic enabling of IOMMU based DMA protection from
possibly malicious devices connected through Thunderbolt ports. In
addition we make sure PCIe ATS (Address Translation Service) is not
enabled for such devices to prevent them from passing IOMMU protection.
Please pull, thanks!
