How did you test this? Have you applied: - "scatterlist: define SG chain for arm architecture" - "iovmm: replace __iounmap with omap_iounmap" - "iovmm: add superpages support to fixed da address" - "iovmm: IVA2 MMU range is from 0x11000000 to 0xFFFFFFFF" - "iovmm: no gap checking for fixed address" Also make sure your baseline have this patch: - "omap:iommu-load cam register before flushing the entry" What kind of error are you getting? I don't have a complete framework to test MM testcases at this moment I did not stress test but a bridge level, and they were good, just some Mailbox issues beucase of the lack of some patches. So I was waiting All missing patches are merge in order to do more stressing testing because I think there is some race conditions in iommu module that need to be fixed. You can email me the case and erros you are facing privately and I will Check them, maybe it is because of missing patches.
