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.
Regards,
Fernando.
