fmr is in part of gen2 stack. Look in ib_verbs.h for struct ib_fmr.

Hello -
I am attempting to port some code from gen1 to gen2, has fmr
been deprecated? What -is- fmr and how does it differ from a mr? If I am
correct the type struct ib_mr has become struct ibv_mr...
Any insight (or information on where I can find more info about
this) is great

Hi!
With mstflint, you can now use mthca device names, as follows:
./mstflint -d /sys/class/infiniband/mthca0/device/resource0 q
Thanks,

Hello,
There is a problem with ibverbs library if it is not linked with an
application but dynamically loaded by the application in runtime by
dlopen(). It can't load userspace device-specific driver in later case.
Two programs are attached to demonstrate the problem. Compile first one
with:
$ g
ucm library location is /usr/local/lib rather than
/usr/local/lib/infiniband
