Chapter 13: VME Device Attachment

This chapter contains useful background information if you plan to control a VME device from a user-level program. It contains important details on VME addressing if you are writing a kernel-level VME device driver.

• "Overview of the VME Bus" summarizes the history and features of the VME bus architecture.

• "VME Bus in Silicon Graphics Systems" gives an overview of how the VME bus is integrated into Silicon Graphics computer systems.

• "VME Bus Addresses and System Addresses" discusses the relationship between addresses on the VME bus and addresses in the physical address space of the system.

• "Configuring VME Devices" tells how to configure a device so that IRIX can recognize it and initialize its device driver.

• "VME Hardware in Challenge and Onyx Systems" documents the hardware details of the VME implementation on those systems.

• Chapter 4, "User-Level Access to VME and EISA," covers PIO and DMA access from the user process.

• Chapter 14, "Services for VME Drivers,"discusses the kernel services used by a kernel-level VME device driver, and contains an example.
