Really? The idea of FMR, I thought, was to preallocate the TPT entry up front (alloc_fmr), and then populate it with the lightweight fmr api (map_phys_fmr). If I use ib_reg_phys_mr(), then I incur all the preallocation overhead each time. Sure the benefit of an FMR isn't merely that the hard work is deferred, opening a vulnerability while it's pending?? >No chance. You need to implement MW allocation in mthca.
