FlexRIO for Linux, Version 17.0.0

-------------------------------------------------------------------------------
This file contains late-breaking news about FlexRIO and supersedes any
information found in other documentation included in the distribution. Refer to
ni.com/linux for the most recent information about Linux support from National
Instruments.

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

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

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

The following 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 FlexRIO Driver and FPGA Interface C API" section for more
information.

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

FlexRIO for Linux requires one of the following distributions:

* Red Hat Enterprise Linux 6.x x86_64
* Red Hat Enterprise Linux 7.x x86_64
* Scientific Linux 6.x x86_64
* openSUSE Leap 42.1 x86_64
* openSUSE Leap 42.2 x86_64
* CentOS 7 x86_64

FlexRIO 17.0 no longer officially supports x86 systems, and it is important to
note that on x86 systems with memory or memory-mapped devices beyond the first
4 GB of physical address space, FlexRIO will fail to load altogether. This
limitation does not apply to x86_64 systems. To ensure the successful operation
of National Instruments 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
NI, refer to ni.com/linux.

In order to use 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 FlexRIO Driver and FPGA Interface C API"
section for more information about developing LabVIEW FPGA applications
with Windows systems.

---------------------------------------------------------------------
Dropped Support for 32-bit Linux distributions
---------------------------------------------------------------------

FlexRIO for Linux has dropped support for Intel 32-bit
versions of Linux distributions as of July 1, 2016. Versions of
FlexRIO for Linux that ship after July 1, 2016 may install and execute on
Intel 32-bit distributions, but official support is not provided.

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

Note: To ensure that the installation completes successfully, you must
uninstall any previous version of FlexRIO before you install the
current version. For information about uninstalling an old version of
FlexRIO, refer to the readme for that version.

To install FlexRIO for Linux, run the INSTALL script from this directory as
root. The INSTALL script ensures that all requirements are met before
installing the FlexRIO software. The script then uses RPM to install the
content of the 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 FlexRIO drivers are loaded by default at boot time
if there is a FlexRIO device in the system.

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

You must begin development on a computer running Windows.
1. Use LabVIEW FPGA to develop and build an FPGA VI that runs on a
   FlexRIO device.
2. 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.
3. 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 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 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 FlexRIO for
Linux supports triggering only on x86 versions of Linux.

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

Complete the following steps to remotely access FlexRIO devices on your Linux
system from another system with 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 FlexRIO devices on this
   system, the RIO server searches 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
-----------------

To create RIO aliases to local or remote FlexRIO devices, you must edit
the nirio.ini file at /var/local/natinst/nirio/etc/. 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 '_'.

Next, change the following version lines to 0:

   [General]
   MajorVersion=0
   MinorVersion=0

This triggers nirio.ini to be updated the next time it is used.
After running "lsni", note that the [Aliases] section has been replaced
by a new section for each new alias.

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

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

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

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 Embedded controllers:

* PXIe-8101
* PXIe-8108

Supported PXI Express chassis:

* PXIe-1062Q
* PXIe-1065
* PXIe-1075
* PXIe-1082

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.

FAQ
---

Q1: I am not using one of the distributions listed as supported above. Will
    FlexRIO still work?

A1: The distributions above have been tested and verfied by National
    Instruments. Other distributions may work, but you should test extensively
    before deploying a system using such a configuration. For information about
    which Linux distributions National Instruments supports, go to ni.com/info
    and enter the Info Code nilinuxdistro.

Q2: My application used to work, but I updated my kernel and now I'm getting

    "libnipalu.so failed to initialize
    Perhaps you need to run updateNIDrivers
    Aborted"

    Will my application work?

A2: The FlexRIO and supporting drivers must be built with the kernel sources
    for the kernel that is in use. As root, run "updateNIDrivers" and restart
    to fix the issue.

Q3: I am using a PXI controller and I have installed PXI Platform Services on my
    x86 version of Linux, but when I run "lsni -v" I don't see any PXI-specific
    information. What is wrong?

A3: You must reboot after installing PXI Platform Services to see PXI-specific
    information.

Q4: Does FlexRIO support native x86_64 applications?

A4: As of NI-RIO 12.0.0, native x86_64 applications are supported.

Q5: When I run "lsni" I get the error "version 'GLIBCXX_3.4.9' not found."

A5: For information about this issue, go to ni.com/info and enter the Info Code
