The reservation will only fail when there is no memory. If a software restriction is needed we could define a start and end addresses for iommu module (maybe as a parameter when the iommu handle for iva2 is got) and that boundaries can be taking in account at the moment of reserve the memory. What happened to this? IIUC what you are proposing is to remove the DMM pool completely, that makes sense to me. However, is it really needed to finish the iommu migration to do this? > I think the reserve/unreserved dspbridge api can disappear and just return the da address in the map function. This is something I've proposed before, so I agree :) -- Felipe Contreras -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
