Copying the Driver to a Module Directory

Device drivers reside in different directories depending on the platform they run on and whether they are needed at boot time. Platform-dependent device drivers reside in the following locations:

• /platform/`uname -i`/kernel/drv - Contains drivers that run only on a specific platform, such as the Ultra^TM 2

• /platform/`uname -m`/kernel/drv - Contains drivers that run on a family of platforms, such as Ultra 1 and Ultra 2 platforms. This directory may not be present on all platforms.

  Platform-independent drivers reside in either of these directories:

• /usr/kernel/drv - Contains drivers not required for system booting

• /kernel/drv - Contains drivers required for booting

To install a driver, the driver and its configuration file must be copied to a drv directory in the module path. For example, to copy a driver to /usr/kernel/drv, type:

$ su# cp xx /usr/kernel/drv# cp xx.conf /usr/kernel/drv

Optionally Editing /etc/devlink.tab

If the driver creates minor nodes that do not represent disks, tapes, or ports (terminal devices), /etc/devlink.tab can be modified to cause devlinks(1M) to create logical device names in /dev. See devlink.tab(4) for a description of the syntax of this file.

Alternatively, logical names can be created by a program run at driver installation time.
