OPENIB.ORG INFINIBAND SUPPORT (2004-03-16 drop)
 ---------- ---------- -------

 This file gives a basic outline of installing and using the kernel
 components of the OpenIB.org InfiniBand stack. More information,
 userspace tools, and the latest kernel drivers are available from
 <http://openib.org/>

 INSTALLATION
 ------------

 Copy the infiniband/ directory to the drivers/ directory in a 2.6
 kernel source tree. Apply the drivers.diff patch to the kernel so
 that InfiniBand support is enabled in the kernel configuration.
 Reconfigure the kernel with all CONFIG_INFINIBAND_XXX options set to
 'm' and rebuild the kernel.

 If you wish to build SDP support, you will have to obtain the
 infiniband-kernel-sdp package and copy those sources into
 drivers/infiniband/ulp/sdp before building.

 By adding

 alias infiniband_hca ib_tavor

 alias ib0 ib_ipoib
 alias ib1 ib_ipoib

 alias net-pf-26 ib_sdp

 to /etc/modprobe.conf, IP-over-InfiniBand (IPoIB) can be enabled
 simply by running

 ifconfig ib0 <netaddress> # HCA port 1
 ifconfig ib1 <netaddress> # HCA port 1

 Once IPoIB is configured and running, Sockets Direct Protocol (SDP)
 can be used by creating a SOCK_STREAM socket with protocol family 26
 (AF_INET_SDP).

 SCSI RDMA Protocol (SRP) is used by running

 modprobe ib_srp

 InfiniBand attached storage will appear as normal SCSI devices.


 Some debugging information is available in the files in the
 /proc/infiniband directory. Of particular interest are the
 /proc/infiniband/ca1/port1/info and /proc/infiniband/ca1/port2/info
 files, which among other things show the state of the HCA's ports.

 NOTES
 -----

 2004-03-16 -- Updated drop

 * Bugfix to Mellanox HCA driver spinlock wrapper.
 * Remove GPL-only rbtree code that was inadvertently included.

 2004-03-05 -- Updated drop

 * Some updates to source code. Issues below for 2004-02-26 drop
 still apply.
 * Split SDP source with questionable license into a separate
 package.

 2004-02-26 -- Initial drop

 * This drop only supports Linux kernel version 2.6.
 * This drop has only been tested on i386.
 * InfiniBand support will not work if compiled staticly into the
 kernel due to link order issues. Set all CONFIG_INFINIBAND
 options to 'm'.
