NI FlexRIO for Linux
----------------------

NI FlexRIO for Linux contains the NI FlexRIO drivers, the NI FlexRIO shared
library, the FPGA Interface C API runtimelibrary, and all supporting runtime
libraries and services necessary to interact with an NI FlexRIO device from a
system running Linux.

-----------------------------------
Differences from the Windows Driver
-----------------------------------

The following NI FlexRIO driver features supported for Windows are not
supported for Linux:

* Development of LabVIEW FPGA VIs and bitfiles (*.lvbitx)
* Development of LabVIEW FPGA Interface host VIs

You must compile a bitfile using LabVIEW FPGA on a Windows machine. Refer to
the "Using the NI FlexRIO Driver and FPGA Interface C API" section for more
information.

-------------------
System Requirements
-------------------

NI FlexRIO for Linux requires one of the following distributions:

* Red Hat Enterprise Linux 5.x i386
* Red Hat Enterprise Linux 5.x x86_64
* Red Hat Enterprise Linux 6.x i386
* Red Hat Enterprise Linux 6.x x86_64
* Scientific Linux 5.x i386
* Scientific Linux 5.x x86_64
* Scientific Linux 6.x i386
* Scientific Linux 6.x x86_64
* openSUSE 12.1 i386
* openSUSE 12.1 x86_64
* openSUSE 12.2 i386
* openSUSE 12.2 x86_64

NI FlexRIO does not support x86 systems with memory or memory-mapped devices
beyond the first 4 GB of physical address space. NI FlexRIO will fail to load
if it detects hardware beyond this address limit. This limitation does not
apply to x86_64 systems. To ensure the successful operation of National
Instruments NI FlexRIO products on x86 systems, you must use a kernel
configuration that recognizes only up to 4 GB of physical memory. Refer to the
documentation of your Linux distribution to determine how to configure the
distribution installer to select an appropriate kernel. Alternatively, you can
dynamically restrict the addressable range of the kernel to a specific limit by
passing "mem=" to the kernel at boot time. For example, to restrict the
kernel to 3 GB of addressable physical space, specify "mem=3072M".

For more information about Linux versions and distributions supported by
National Instruments, refer to ni.com/linux.

In order to use NI FlexRIO on Linux, you need a Windows system to develop your
LabVIEW FPGA application. You must compile a bitfile, generate headers with the
FPGA Interface C API Generator, and then move the application to your Linux
system. Refer to the "Using the NI FlexRIO Driver and FPGA Interface C API"
section for more information.

---------------------------
Installing NI FlexRIO for Linux
---------------------------

Before installing this version of NI FlexRIO, uninstall any previous versions of
NI-RIO or NI FlexRIO. For information about uninstalling an old version of
NI FlexRIO or NI-RIO, refer to the readme for that version.

To install NI FlexRIO for Linux, run the INSTALL script from this directory as
root. The INSTALL script ensures that all requirements are met before
installing the NI FlexRIO software. The script then uses RPM to install the
content of the NI FlexRIO packages in /usr/local/natinst/. The script also
creates links in /usr/local/lib/ to libraries in /usr/local/natinst/.

Missing dependencies will cause the installer to fail. The most commonly
missing dependencies are GCC and kernel sources. For distributions managed with
yum, the following command can install those dependencies:

   yum install gcc kernel-devel-$(uname -r)

For other distributions, refer to the documentation for your distribution.

During installation on openSUSE, you may see the following error message:
"Kernel source does not appear to be configured for the running kernel.
Configuration of kernel source is required to continue installation." This
message can occur even if you have installed the correct kernel sources, if the
sources require configuration. This problem may affect other distributions in
addition to openSUSE.

Complete the following steps to configure your kernel sources on openSUSE:
1. Install the kernel-source package corresponding to the version of the kernel
   you are using. For versions of openSUSE earlier than 11.3, you also need to
   install the corresponding kernel-syms package. You can determine which
   version of the kernel is running with the command "uname -r".
2. Change the directory to /usr/src/linux-, where is the
   version number of the kernel.
3. Run "zcat /boot/symvers-.gz > Module.symvers" as root to prepare
   modversion support.
4. Run "make cloneconfig" as root to configure the sources for the kernel.
5. Run "make modules_prepare" as root to prepare the headers for compilation.

After installing all missing dependencies, run the INSTALL script again.

Once the INSTALL script completes successfully, reboot the system to ensure
that all the drivers are updated.

After installation, the NI FlexRIO drivers are loaded by default at boot time
if there is an NI FlexRIO device in the system.

------------------------------------------------
Using the NI FlexRIO Driver and FPGA Interface C API
------------------------------------------------

You must begin development on a computer running Windows. Use LabVIEW FPGA to
develop and build an FPGA VI that runs on an NI FlexRIO device. Use the FPGA
Interface C API Generator to create the C source files for your application.
Go to ni.com/info and enter the Info Code fpgainterfacecapi to get the latest
version of the FPGA Interface C API Generator. Then copy the generated files
to the Linux machine to begin development of C/C++ code for your application.
For information about using the FPGA Interface C API, go to ni.com/info and
enter the Info Code fpgainterfacecapihelp.

To find the NI FlexRIO device you are using in your application, use the command
"lsni -v" to list information on all National Instruments devices in the
system.

If your application requires triggering, you can reserve triggers statically
with the NI PXI Config utility or dynamically with NI-VISA. For information
about using these configuring PXI systems in Linux, go to ni.com/info and enter
the Info Code linuxconfigpxi. For information about PXI triggering, go to
ni.com/info and enter the Info Code pxitrigger. This version of NI FlexRIO for
Linux supports triggering only on x86 versions of Linux.

-----------------------
Using the NI-RIO Server
-----------------------

Complete the following steps to remotely access NI FlexRIO devices on your Linux
system from another system with NI FlexRIO installed:

1. Select a port for the NI-RIO server to use. The default port is 11296.
2. Configure the system firewall to allow TCP connections through the selected
port.
3. Edit the nirio.ini file at /etc/natinst/nirio/ to specify both the selected
port and the users allowed to access the device. The following example
specifies the default port, 11296, and allows only users at the IP address
10.0.29.54 to have access to the device:

   [General]
   RpcServerPort=11296
   DeviceAccess="-*;+10.0.29.54"

4. Execute NiRioRpcServer at /usr/local/natinst/nirio/bin/.

Note that the DeviceAccess variable is defined by a semicolon-delimited list of
qualifiers, IP addresses, DNS hostnames, and wildcard patterns. To determine
whether a remote system has access to NI FlexRIO devices on this system, the RIO
server looks for an entry in the list that matches the remote system. The "+"
qualifier allows access, and the "-" qualifier denies access. The RIO server
uses the last matching entry in the list to determine whether to allow or deny
access. If no entry matches the remote system, the RIO server denies access.
For example, if the list is empty, all remote systems are denied access. The
first argument in the example above explicitly restricts remote access from any
IP address. The second argument allows access from the IP address 10.0.29.54.
To allow access from multiple IP addresses, define DeviceAccess as follows:

   DeviceAccess="+10.0.29.54;+10.0.35.42"

To allow access from any IP address on the network, define Device Access as
follows:

   DeviceAccess="+*"

-----------------
Using RIO Aliases
-----------------

In order to create RIO aliases to local or remote NI FlexRIO devices, one must
edit the nirio.ini file at /etc/natinst/nirio/. Add an [Aliases] section if one
does not already exist. For each alias, there must be a separate line in the
[Aliases] section that follows the ="" format. The following
example specifies both a local and remote alias:

   [Aliases]
   foo="RIO0"
   bar="rio://mycrio/RIO0"

Note that aliases must contain only alphanumerics, '-', and '_'.

-----------------------------
Uninstalling NI FlexRIO for Linux
-----------------------------

To uninstall the driver and its dependencies, run the UNINSTALL script.

--------------------------------
Running Linux on PXI Controllers
--------------------------------

NI FlexRIO for Linux works with all PXI and PXI Express controllers and chassis.
However, to use PXI Express features, you must install the PXI Platform
Services driver 2.6 (not included with this installer), use an x86 version of
Linux, and use a PXI Express controller and chassis.

PXI Express features:

* NI-P2P streaming
* Slot and chassis identification
* Trigger bus number identification (for trigger reservation)

Supported PXI Express controllers:

* PXIe-8101
* PXIe-8108

Supported PXI Express chassis:

* Any PXI Express chassis except the PXIe-1073

To install the PXI Platform Services driver, go to ni.com/info and enter the
Info Code linuxpxidriver. For installation and configuration notes specific to
each controller, go to ni.com/info and enter the Info Code linuxpxiembedded.
