git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu # # Pull IOMMU updates from Joerg Roedel: # # - PASID table handling updates for the Intel VT-d driver. It implements # a global PASID space now so that applications usings multiple devices # will just have one PASID. # # - A new config option to make iommu passthroug mode the default. # # - New sysfs attribute for iommu groups to export the type of the # default domain. # # - A debugfs interface (for debug only) usable by IOMMU drivers to # export internals to user-space. # # - R-Car Gen3 SoCs support for the ipmmu-vmsa driver # # - The ARM-SMMU now aborts transactions from unknown devices and devices # not attached to any domain. # # - Various cleanups and smaller fixes all over the place.
