Setting ipg Driver Parameters Using a qfe.conf File

1. Invoke the prtconf -v command and pipe the output to the more command ( prtconf -v | more ) or redirect the output of the command to a file name ( prtconf -v > filename) and print the redirected file.

2. Find the section in the prtconf -v output for SUNW,qfe,instance #0, or SUNW,qfe,instance #1, and so on.

   The output for SUNW,qfe,instance #0 for a Sun Ultra 1 Creator Series system follows:

   ---

   SUNW,qfe, instance #0
               Driver software properties:
                   name <pm_norm_pwr> length <4>
                       value <0x00000001>.
                   name <pm_timestamp> length <4>
                       value <0x30743b26>.
               Register Specifications:
                   Bus Type=0xe, Address=0x8c00000, Size=108
                   Bus Type=0xe, Address=0x8c02000, Size=2000
                   Bus Type=0xe, Address=0x8c04000, Size=2000
                   Bus Type=0xe, Address=0x8c06000, Size=2000
                   Bus Type=0xe, Address=0x8c07000, Size=20

3. Become superuser.

4. Create the qfe.conf file in the /kernel/drv directory using a text editor and add lines similar to the following to the file:

   1. Specify name="qfe" and class="sbus".

   2. Use the reg property to specify the device, 0xe in this case. Use the value following Bus Type in the prtconf -v output.

   3. Type the addresses followed by the specified sizes. Precede each size with 0x and leading zeros, as indicated in the following screen.

   4. Set ipg1 and ipg2. Type a semicolon ( ; ) after the last value.

      These parameters are set to 20 and 10, respectively, in this example. The ipg parameters are defined in Chapter 3.

      ---

      name="qfe" class="sbus"
      reg=0xe,0x8c00000,0x00000108,0xe,0x8c02000,0x00002000,0xe,
      0x8c04000,0x00002000,0xe,0x8c06000,0x00002000,0xe,0x8c07000,
      0x00000020
      ipg1=20 ipg2=10;

5. Save the qfe.conf file.

6. Save and close all files and exit all programs; exit the windowing system.

7. Halt and reboot the system by typing the init 6 command at the # prompt.
