Hello, Maybe we can disable only Exynos IOMMU in configs for now? Same way it is disabled in current exynos_defconfig here https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/arch/... As i understand it is broken for all exynos devices not only snow. --- Best Regards, Misha Komarovskiy zombahatgmaildotcom On Thu, Jul 23, 2015 at 4:29 PM, Alexander Graf <agraf@suse.de> wrote:

Hrm, rather than disable it one way or another manually, couldn't we just blacklist it inside the kernel? I doubt that we can load iommu as module...
You mean as in patch the iommu probe code to check for "google,snow", "google,spring", etc.?
For example - or remove the respective dt node. Or as a property to the IOMMU dt node...
