Support for the linux zhpe bridge device driver

1. Install dependencies

$ sudo -i apt-get install build-essential linux-headers-$(uname -r) cmake valgrind libudev-dev git wget flex
$ sudo -i apt-get build-dep openmpi libtool
$ sudo -i apt-get install librdmacm-dev # optional: not needed if OFED installed or verbs not required

2. Install libtool from source

$ wget http://ftpmirror.gnu.org/libtool/libtool-2.4.6.tar.gz
$ tar -xzf libtool-2.4.6.tar.gz
$ cd libtool-2.4.6
$ ./configure
$ make	
$ sudo make install

Make sure the new version of libtoolize is first in your PATH.

Building the driver and helper (using DKMS or manually)

DKMS method

This method has several advantages; it will manage building and installing the driver for multiple kernel versions, it automatically supplies driver parameters when the driver is loaded and handles all the driver build steps.

1. Install DKMS package

$ sudo -i apt-get install dkms

2. Clone zhpe-support into ${SRC_DIR}

$ cd ${SRC_DIR}
$ git clone https://github.hpe.com/zhpe-support.git

3. Register zhpe-support with DKMS (note driver version for build/install commands)

$ sudo -i dkms add ${PWD}/zhpe-support

4. Build and install driver

$ sudo -i dkms build zhpe/<driver_version> -k <kernel_version>
$ sudo -i dkms install zhpe/<driver_version> -k <kernel_version>

5. Load driver into kernel

$ sudo -i modprobe zhpe

6. Unload driver and uninstall

$ sudo -i modprobe -r zhpe
$ sudo -i dkms uninstall zhpe/<driver_version> -k <kernel_version>

7. Remove driver from DKMS

$ sudo -i dkms remove zhpe/<driver_version> -k <kernel_version>

Manual method (build into ${TEST_DIR})

NOTE: Builds in the zhpe-support tree currently install automatically into ${TEST_DIR}. This is not true for zhpe-libfabric and zhpe-ompi.

1. Clone zhpe-support into ${SRC_DIR}

$ cd ${SRC_DIR}
$ git clone https://github.com/HewlettPackard/zhpe-support.git

2. Generate makefiles and build and load driver.

$ cd ${SRC_DIR}/zhpe-support
$ make
$ sudo -i insmod ${TEST_DIR}/lib/modules/zhpe.ko
