Hi all, According to the routine of iommu_dma_alloc(), it allocates an iova then does iommu_map() to map the iova to a physical address of new allocated pages. However, in remoteproc_core.c, I see its code try to iommu_map() without having an alloc_iova() or alloc_iova_fast(). Is it safe to do so? If an iova range is not allocated but mapped, would a later iommu_dma_alloc() happen to hit this iova range when doing its alloc_iova() and then fail to map? And I am not very familiar with remoteproc code, so if I am missing something, please kindly educate me. Thanks Nicolin
