Hi Will, I am trying to enable SMMU(mmu500) on an platform. My platform support only 32 SIDs, but it have more than 100 masters. So I need to let different masters share one SID. I read current arm-smmu.c, but it needs each master has unique SID. Do you have some suggestions about how to let different masters sharing one SID?
On my platform, SID can be dynamically programmed. So I can program DMA0 and DMA1 using one SID, saying 0x5. But I do not have a good idea how to support this use case in arm-smmu.c driver. Thanks, Peng. _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
