This README is for userspace cm library.
Building
To make this directory, run:
./autogen.sh && ./configure && make && make install
Typically the autogen and configure steps only need be done the first
time unless configure.in or Makefile.am changes.
Libraries are installed by default at /usr/local/lib.
Device files
The userspace CM uses a device file per adapter present.
To create the appropriate character device file automatically with
udev, a rule like
KERNEL="ucm*", NAME="infiniband/%k", MODE="0666"
can be used. This will create the device node named
/dev/infiniband/ucm0
for the first HCA in the system, or you can create it manually
mknod /dev/infiniband/ucm0 c 231 224
