Prerequisites
RedHawk Linux Version 5.4 Release Notes 7
3.0. Prerequisites
3.1 Software
No previously installed software is required in order to install RedHawk Linux. The complete
RedHawk Linux installation consists of the following software:
• Red Hat Enterprise Linux 5.4 with updates
• RedHawk Linux operating system
• NightStar RT for RedHawk tools (optional)
• RedHawk Linux Frequency-Based Scheduler (FBS) (optional)
• RedHawk Linux PCI-to-VME bridge software (optional)
• RedHawk Linux Cluster Manager (optional)
• RedHawk High Availability NFS (HA-NFS) (optional)
• RedHawk Global File System (GFS) (optional)
These packages operate in either a 32-bit or 64-bit environment. The operating environment on
a system depends upon the processor type and the support included in the software for that
processor. Refer to “Product Media” on page 2 for details.
NOTE
Real-time extensions and features are not available to 32-bit
applications running under a 64-bit operating system (i.e.
x86_64). In order to use real-time features, migrate 32-bit
applications to 64-bit (described in Appendix E of the RedHawk
Linux User’s Guide) or boot a 32-bit operating system instead.
3.2 Hardware
• Any Concurrent iHawk or ImaGen system
• Real-Time Clock and Interrupt Module (RCIM)
