OS Kernel, Drivers, and BSPs

The 21st century brings a dramatic increase in the evolution of technology and, thus, new challenges for OEM vendors, industrial and consumer equipment manufacturers, and software product vendors as they face the tasks that require complex kernel-level development.

Auriga frequently deals with OS kernel, standalone driver, and Board Support Package (BSP) development projects for both OS and board vendors. Auriga has developed diversified expertise with multiple types of peripherals and processor architectures and a wide variety of operating systems. This accumulated experience and knowledge enable Auriga to create any driver for virtually any OS/device combination.

OS Kernel Internals: Windows, Linux, UNIX, RTOS

Auriga engineers always demonstrate a keen insight into kernel-related technologies, allowing Auriga to offer highly customizable solutions tailored to meet unique needs. Auriga delivers the following kernel-level services:

  • Custom kernel development services tailored individually to meet the unique needs of Auriga’s clients. Auriga’s extensive development background ranges from enhancing kernel functionality to kernel modification to many other working solutions.
  • Kernel testing, analysis, and defect fixing—kernel-related defect analysis, issue identification, and efficient solution development and implementation
  • Kernel-level driver development
  • Kernel porting of any complexity

Device drivers

The development of stable, reliable, and maintainable device drivers requires specialized knowledge, experience, and tools. Auriga has acquired considerable expertise backed by 20+ years of working on a large number of projects involving development, maintenance, and testing of a variety of device drivers. The experience gained by Auriga enables the development of device drivers for virtually any type of I/O or DMA device in a process-oriented, predictable manner. Some examples of driver development projects for specific devices include:

  • Hot swap drivers for NMS AG family boards (CPCI form factor)
  • FibreChannel Device Driver Suite and many other drivers for LynxOS real-time OS
  • I/O co-processor control and management system, including a set of drivers and associated APIs for Digital UNIX
  • Network interface card drivers for LynxOS and Linux
  • Network adapter (NDIS) drivers for Windows
  • StarFabric Bus Driver

Board Support Packages (BSPs)

Auriga deals with BSP projects on a regular basis. A board may be equipped with both standard and unique hardware components, so a BSP is a customization of an OS that provides software applications with methods to properly use the board components. Typically, the scope of a BSP development project includes:

  • board-specific core OS (initialization and management of hardware components that are crucial for OS operation—bridges, timers, interrupt controller, etc.);
  • set of device drivers for additional hardware components (on-board and/or peripheral devices) supported by the BSB—Ethernet, hard disk, keyboard and video adapter, etc.);
  • set of interfaces and associated development tools for building the custom software on top of the BSP.
