4. The FRMR api need to set key of MR through IB_WR_REG_MR. But it is impossible to change a key of mr using uverbs.FRMR is more like memory windows in user space, you can't support it using just regular MRs.It is hard to support this using uverbs, but it is easy to support with uRDMA that we can get full control of mrs.What is uRDMA?uRDMA is a software implementation of the RoCEv2 protocol like rxe. We will implement it in QEMU with VFIO or DPDK.
ok, thanks
Thanks. Junji
