Chapter 6 NI-VXI Configuration Utility
Note This field is effective only when the PCI-MXI-2 is at its default logical address of 0.
The PCI-MXI-2 is the Resource Manager only if its logical address is 0.
VXI/VME-PCI8026 for Linux
The device type affects only the contents of the Device Class field in the
Device Type register. The functionality of the other registers does not
change.

Address Space

This field indicates the addressing mode(s) of the device's operational
registers. The PCI-MXI-2 can be configured in one of three ways. The
default addressing mode is for A16 space only. Your other options are
A16/A24 and A16/A32.
Notice that the options in the VXI/VME Shared Memory group are
disabled when the addressing mode is A16. Only if you select A16/A24
or A16/A32 are the following options relevant:
• VXI/VME Shared RAM Size
• Shared RAM Pool
• Advanced
– Byte Swapping
– Memory Select
– Mapping

VXI/VME Shared Memory

Linux does not support sharing of system RAM. You can, however, share
RAM that is installed on the VXI-MXI-2 or VME-MXI-2.

Resource Manager

The only option under the Resource Manager portion of the Logical
Address Configuration Editor is the Resource Manager Delay option.

Resource Manager Delay

This field specifies the time in seconds that the Resource Manager (RM)
waits before accessing any other VXI/VMEbus device's A16 configuration
registers.
RM Delay Range
0 to 65535 s
6-4
Default Value
5
