To build NI-PCI/GPIB PCI PassThrough device driver do the following:

Step	Description
1	Make sure that the required building tools and include files are installed. If they are absent install them: `# yum groupinstall “Development Tools”` # yum `# yum groupinstall "Development Tools"` `# yum install kernel-headers kernel-devel` Note: The kernel version must match the version of the installed kernel-headers (i.e. this packages must have same versions. It can be verified via `"rpm -q -a \| grep kernel-`" ) Check that the "kernel" and the "kernel-headers" have the same version, and ensure that system is booted from this kernel version (not from some older one and etc) with "`uname -a`" command.
2	Open xterm and change the default directory to "`/opt/charon/drivers/ni_pci_gpib_ppt`": # cd `#` `cd /opt/charon/drivers/ni_pci_gpib_ppt`
3	Issue "make clean; make" commands to build kernel object: # make `# make clean; make` It is prohibited to use a module built on a certain version of kernel on another one.
4	Check that there are no compilation errors and the file "`ni_pci_gpib_ppt.ko`" has been built

To install NI-PCI/GPIB PCI PassThrough device driver do the following:

Step Description

1

Load "ppt_kgpsa.ko" driver; to do that issue the following command:

# insmod

# insmod ni_pci_gpib_ppt.ko

2

Issue "dmesg" command and check that no error appeared during the driver loading, also check that the driver has found all GPIB devices:

# dmesg

# dmesg

To add NI-PCI/GPIB PCI PassThrough device driver to Linux startup do the following:

Step Description

1 Disable auto-loading of device drivers from National Instruments on boot (if available). Use the black list file "/etc/modprobe.d/blacklist.conf" to do that.

2

Copy the GPIB kernel module to the location of Linux kernel modules, for example:

Div

class	small

# cp /opt/charon/drivers/ni_pci_gpib_ppt/ni_pci_gpib_ppt.ko /lib/modules/3.10.9-200.el74.x86_64/kernel/drivers/

The particular path may be different, depending on the kernel version and Linux distribution.

3

Enable auto load of the module:

# echo ni

# echo ni_pci_gpib_

ppt >

ppt > /etc/modules-load.d/ni_pci_gpib_ppt.conf

4

Regenerate new "initramfs" image with "mkinitrd":

# mkinitrd -f /boot/initramfs-3.10.9-200.el74.x86_64.img 3.10.9-200.el74.x86_64

The particular path may be different, depending on the kernel version and Linux distribution.

VAX configuration

load IEQ11 IEA


set IEA host_bus_location[0] = "/dev/gpib<N>"
set IEA host_bus_location[1] = "/dev/gpib<M>"

Example:

load IEQ11 IEA

set IEA host_bus_location[0] = "/dev/gpib0"
set IEA host_bus_location[1] = "/dev/gpib1"

...

load IEQ11 IEA vector = 0270 priority = 6
set IEA host_bus_location[0] = "/dev/gpib<N>"
set IEA host_bus_location[1] = "/dev/gpib<M>"

...

load IEQ11 IEA vector = 0270 priority = 6

set IEA host_bus_location[0] = "/dev/gpib0"
set IEA host_bus_location[1] = "/dev/gpib1"
