Driver Installation Under FreeBSD

h

Add the following line to “Makefile.i386’

CFLAGS+=-I/sys/dev/twa

i

If you intend to bundle the firmware image with the driver, 
add the following line to /sys/conf/options:

TWA_FIRMWARE_FLASH opt_twa.h

and the following line to your kernel configuration file 
(“custom” in the example above):

options TWA_FLASH_FIRMWARE

j

If you intend to enable printing of debug messages in the 
driver, add the following line to /sys/conf/options:

TWA_DEBUG

opt_twa.h

and the following line to your kernel configuration file 
(“custom” in the example above):

options

TWA_DEBUG=

<number from 0 to 10>

Specifying 0 in the above line prints no debug messages, 
whereas specifying 10 prints a LOT of debug messages.

5

Rebuild the kernel and install the new kernel.

6

Reboot with the rebuilt kernel.

Compiling the Driver as a Loadable 

Module

If you wish to compile the driver yourself (for a different kernel 
version that you are running), then perform the following steps.

1

Create the directories /sys/modules/twa and /sys/dev/twa

mkdir /sys/modules/twa

mkdir /sys/dev/twa

2

Copy the 3ware driver source file archive (twa.tgz) to 

 

/sys/dev/twa

.
