Hello Guillaume, I tested both exynos_defconfig and multi_v7_defconfig, they work fine. But ill test lpae config without EXYNOS_IOMMU today and will report. --- Best Regards, Misha Komarovskiy zombahatgmaildotcom On Mon, Aug 17, 2015 at 9:59 AM, Guillaume Gardet <guillaume.gardet@free.fr> wrote:

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.
That is exactly what I would like to do since I read this thread: https://lkml.org/lkml/2015/2/17/163
Before submitting the idea here, I wanted to check if disabling Exynos IOMMU in config was enough. I had only time to test the exynos_defconfig with openSUSE kernel and it was OK (boot messages and login prompt displayed).

Maybe. Someone with a Chromebook needs to sit down and try. :)
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...
