03:30 <wzyy2> spend some time to write status matrix...

03:30 <wzyy2> http://opensource.rock-chips.com/wiki_Status_Matrix

03:30 <wzyy2> - -though it can't be modified by peoples..

03:43 <wzyy2> Myy, 4.12 or 4,13>

03:43 <wzyy2> 4.13?

03:52 <wzyy2> make sure you didn't enable CONFIG_IOMMU_DMA.

03:53 <stdint> don't try to break the whole system unless you know what you are doing

04:18 <wzyy2> "iommu_domain_free" might be called when driver fail in some where.

04:19 <wzyy2> I have meet it before...

04:27 <wzyy2> "iovad->dma_32bit_pfn = min(end_pfn + 1, iovad->dma_32bit_pfn);" i think it's the root cause.

05:53 <stdint> I would suggest don't starve yourselves into those iommu pool

05:54 <stdint> Those code once written a year ago, both Jun and I don't want to touch them again

05:54 <stdint> if you don't care about speed, just remove those code and flush iommu cache every times
