Three conditions determine a device driver module's path:
The platform that the driver runs on
The architecture for which the driver is compiled
Whether the path is needed at boot time
Device drivers reside in the following locations:
Contains 32-bit drivers that run only on a specific platform.
Contains 64-bit drivers that run only on a specific SPARC-based platform.
Contains 64-bit drivers that run only on a specific x86-based platform.
Contains 32-bit drivers that run only on a specific family of platforms.
Contains 64-bit drivers that run only on a specific family of SPARC-based platforms.
Contains 64-bit drivers that run only on a specific family of x86-based platforms.
Contains 32-bit drivers that are independent of platforms.
Contains 64-bit drivers on SPARC-based systems that are independent of platforms.
Contains 64-bit drivers on x86-based systems that are independent of platforms.
To install a 32-bit 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
To install a SPARC driver, copy the driver to a drv/sparcv9 directory in the module path. Copy the driver configuration file to the drv directory in the module path. For example, to copy a driver to /usr/kernel/drv, you would type:
$ su # cp xx /usr/kernel/drv/sparcv9 # cp xx.conf /usr/kernel/drv
To install a 64-bit x86 driver, copy the driver to a drv/amd64 directory in the module path. Copy the driver configuration file to the drv directory in the module path. For example, to copy a driver to /usr/kernel/drv, you would type:
$ su # cp xx /usr/kernel/drv/amd64 # cp xx.conf /usr/kernel/drv
