NAME

/usr/pil/etc/vxi[lu]/dynamic.cf − This is one of several configuration files used by the ivxirm program. 

DESCRIPTION

Dynamic.cf

This database contains a list of all VXI devices that are to be dynamically Configured (ie. have their logical ID assigned dynamically) by the VXI resource manager. 

The format of this files is as follows:

bus#    slot#    logical_addr

All fields are <tab> seperated.  All values can be expressed in decimal or hex.  During dynamic configuration, each line is read and the first device at the specified slot that responds to the dynamic configuration will be configured.  If this device requires multiple logical_addrs (an address block), then the logical_addr specified is the first in a series that is assigned to the device.  Note that in this case, the logical_addr must be on a correct ADDR boundary, as discussed in the VXI specifications under "Dynamic Configuration - Offset Register". 

After a device is configured, the next line in the file is read and the above steps are repeated. 

Note that this allows multiple devices at a particular slot to be recognized by having multiple lines listed for each slot. 

If an * is specified before the bus number, then two logical address parameters must be specified as follows:

*   bus#   slot#   start_log_addr    stop_log_addr

In this case, the slot is scanned sequentially (low to high) to find all remaining devices in that slot.  They are then assigned logical ADDRs sequentially from start_log_addr to stop_log_addr.  Once stop_log_addr is reached, the next line is read, which may be another ´*´ line. 

When the end of the file is encountered, if there are any more devices that must be dynamically configured, an error is generated by the resource manager.
