Configuring SVR5 MDI drivers

Node file convention

The Node file should contain the appropriate number of entries, up to the number of boards supported by the MAX_BD parameter in your bcfg file. In this example, MAX_BD would be set to 4 in the bcfg file.

Here is a sample DDI 7 Node(DSP/4dsp) file for the foo driver.

   foo     mdi/foo0        c       0       0     0     600
   foo     mdi/foo1        c       1       0     0     600
   foo     mdi/foo2        c       2       0     0     600
   foo     mdi/foo3        c       3       0     0     600

The Node file has a different structure for DDI 8 drivers:

   $maxchan 0
   foo     mdi/foo0%i        c       0       0     0     600

NOTE: The name of the device in /dev/mdi must consist of the driver name followed by a number, starting at 0; minor numbers always start with 0.
