Support for Administratively Provided driver.conf Files

System-provided driver.conf files can be supplemented with administratively provided driver.conf files. Vendor-provided (system-provided) driver data is preserved in the root file system, while administratively provided driver configuration is stored separately in a new /etc/driver/drv directory. The format of an administratively provided driver.conf file is identical to a system-provided driver.conf file.

At boot time, and whenever a driver.conf file for a driver is searched for and loaded, the system will also check for the driver in the driver.conf file within the /etc/driver/drv directory. If found, the system automatically merges the vendor-provider driver.conf files with the local, administratively provided driver.conf files. The driver's view of the system properties consists of these merged properties. Therefore, no driver changes are necessary.

Note that vendor-provided driver.conf files that are in the /kernel and /platform directories can no longer be edited. If you need to supplement a driver's configuration, instead of editing the vendor-provided driver.conf file, add a corresponding driver.conf file to the local /etc/driver/drv directory, then customize that file.

To display the merged properties, use the prtconf command. Note that the prtconf command has a new -u option. This option enables you to display both the original and updated property values for a driver. For instructions, see How to Display Default and Customized Property Values for a Device.
