I've perused the previous discussions on FMRs and I'm still not clear on the following:
Lets say a FMR is allocated with a map count of 4. And the FMR is mapped 4 times, then unmapped. Are the underlying MRs still valid and setup for RDMA from the HW perspective? Or are they marked "INVALID" as part of unmapping? IE: Do they remain valid up to unmap or up to dealloc of the FMR >From the mthca code, all I see is that MTHCA_MPT_STATUS_HW is set while anything is mapped, and MTHCA_MPT_STATUS_SW is set when the unmap is done. I don't know mthca enough to know this is somehow invalidating the MRs in question. Thanks, Steve. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
