The VME Bus

The VME Bus

Each CHALLENGE XL, POWER CHALLENGE, or Onyx system includes full support for the VME interface, including all features of Revision C.2 of the VME specification, and the A64 and D64 modes as defined in Revision D. VME devices can access system memory addresses, and devices on the system bus can access addresses in the VME address space.

The naming of VME devices in /dev/vme, and other administrative issues, are covered in the usrvme(7) reference page.
