Linus Torvalds 6b04014f3f IOMMU Updates for Linux v5.3 ... Including: - Patches to make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers. Goal is to make use of it on x86 too. - Generic IOMMU domain support for the Intel VT-d driver. This driver now makes more use of common IOMMU code to allocate default domains for the devices it handles. - An IOMMU fault reporting API to userspace. With that the IOMMU fault handling can be done in user-space, for example to forward the faults to a VM. - Better handling for reserved regions requested by the firmware. These can be 'relaxed' now, meaning that those don't prevent a device being attached to a VM. - Suspend/Resume support for the Renesas IOMMU driver. - Added support for dumping SVA related fields of the DMAR table in the Intel VT-d driver via debugfs. - A pile of smaller fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEr9jSbILcajRFYWYyK/BELZcBGuMFAl0jaOAACgkQK/BELZcB GuNYTRAAjXuNs1OX/ROJ4TByT3YBWj5BLZVMrpGx75MAEvO68a7rTdaCpGuHv09w 5JneXxA3H2O1q6JCGguLm//Dy5QycJQIn0WuaBGi5Vjo+cGe47sf48Hb6AhIoAFf exjhfmG6kL3ZzEkLU/7iJWqz+iiCBxRU0yMINJvzFFzliJkfyGWsjoruxobmUEhm XdEsdeAQFXoPMNVCDiorM+B+3VCl7BfwfhdlFrmX3fpNrMZ5ytlnPTgfJdXAGgHn DAoK8qGoyYtRnZnivn1y56M13qv5y3XvicKqx/GRKK8CyJpz/vYSBLktI5HO4tOF y/VzNg+ctDSjQgFyKIq+38k6qu4YWctyxZNObmPVpioNf9j9GaZWT97fxGzXMNS4 G7TqOeq4yxjotAOcd+DdH265uVBtGmLqk7XobigxCZ0xzGVVnmPy4oJtkWwjaMgN HtNSMPRRirjprK4BUoCiXwP8YyWZs0a93oJmh2orD406yZkHNuqLNaicu24WsKKf Ze5BsFbNUb0qYdyL7ofOugQrOvYYoWYuREiz8ClF3U4mCcOk4FJ9K2Vf1kSfKBX8 1Skz75NeSZdzXg9JcznNMuiqH2mN3lx/88xKJg3LJxEeFxU++VDMX3Z8kEmpj5w+ 9m/v+VRclUXL6g8s6QFNIlIenMknAEjtWw6hVWPhWLaULH6fR6Y= =Kvk5 -----END PGP SIGNATURE----- Merge tag 'iommu-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu Pull iommu updates from Joerg Roedel: - Make the dma-iommu code more generic so that it can be used outside of the ARM context with other IOMMU drivers.
