I think the concept of iommu groups isn't very well understood, hence the little love it receives from developers who conclude it's useless. I can't blame anyone, I don't do any better. Could I convince you to include documentation in your next patch series that touches iommu groups ? Could you please have a look at my "[RFC/PATCH 0/9] IOMMU probe deferral support" patch series in the context of iommu groups ? The series pretty much drops groups support from the ipmmu-vmsa driver, not because of a real desire to do so, but because I wasn't sure how to keep them. Tips would be appreciated. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
