solved.

Thanks a lot Anatoly.
Will the same solution work with DPDK 19.02 as well? We 're actually using
DPDK 19.02 for memory allocations for SPDK 19.07.
DPDK 19.11 may not be supported by SPDK 19.07 we 're currently using.
I 'll definitely test if the patch works with DPDK 19.02
Thanks again for your

Thanks Anatoly.
I think now we 're close to sync. You understood it right: the problem is
dma/iommu mappings are not getting created.
1)vfio_mem_event_callback() is getting called later when memory is
allocated from heap but not when external memory is added to heap
2)vfio_dma_mem_map() is called

Thanks Anatoly for prompt response. Sorry for the delayed response, I
took some time to reverify with SPDK.
Infact, I do want the iommu mapping to be performed. I don't want it to be
bypassed by type1_map() [lib/librte_eal/linuxapp/eal/eal_vfio.c] for
external memory.
Then, if I understood correc

Thanks Anatoly for reviewing this. Please find my reply inline below:
[Anatoly] First of all, what is "iso-cmem"? It doesn't seem to have any
defined
meaning nor any relation to any existing functionality, and it's not
explained anywhere what is "isolated cmem".
