PCI-MXI-2 for Linux 6-12 ni.com
System IRQ Level
The remote controllers—in this case the VXI/VME-MXI-2—can report
events such as triggers and DMA to the PCI-MXI-2 through a VXI IRQ
line. This field selects which VXI IRQ level the remote controllers should
use to report events to the PCI-MXI-2.
Servant Area Size
This field designates the servant area size, which is supplied to the
Resource Manager in response to the Read Servant Area command (ifthe
PCI-MXI-2 is not the Resource Manager in your system). The servant area
size is an 8-bit value (0 through 255) that indicates the servant area. The
servant area begins at the logical address following the PCI-MXI-2 logical
address, and includes N contiguous logical addresses, where N is the value
of the servant area size. This field is meaningful only when the PCI-MXI-2
is configured as a message-based device.
Note If the PCI-MXI-2 is the Resource Manager (Logical Address 0), this setting is
irrelevant.
Number of Handlers
This field gives the number of interrupt handlers that the PCI-MXI-2
supports.
Interrupt Request Levels Default Value
1 to 7 1
Servant Area Range Default Value
0 to 255 0
Interrupt Handlers Default Value
0 to 7 1
