Chapter 6: FreeBSD Driver Installation
Updating Drivers in the FreeBSD System
e. In the /usr/src/sys/conf/ file, perform the following steps for the mfi driver or the mrsas driver,
depending on which driver you use:
For the mfi driver, add the following entries after the entry for dev/mfi/mfi_cam.c:
dev/mfi/mfi_syspd.c optional mfi
With LSI 2208-based RAID controller support, if your mfi driver is older than 4.408.xx.xx, and you do not
have mrsas.ko driver in your system, also add the following:
dev/mfi/mfi_fp.c optional mfi
dev/mfi/mfi_tbolt.c optional mfi
For the mrsas driver, make sure the following entries are present:
dev/mrsas/mrsas.c optional mrsas
dev/mrsas/mrsas_cam.c optional mrsas
dev/mrsas/mrsas_ioctl.c optional mrsas
f. Save your changes.
g. To compile the kernel, go to the /usr/src directory, type the following commands, and press Enter.
# cd /usr/src
# make buildkernel KERNCONF=MYKERNEL
h. To install the new kernel, type the following commands, and press Enter.
# make installkernel KERNCONF=MYKERNEL
The new kernel is copied to the /boot/kernel directory.
The old kernel is moved to the /boot/kernel.old directory.
6. Reboot your system to use the new kernel.
When the system reboots, the new kernel driver module loads automatically.
6.6.2 Compiling and Loading the Driver as a Module by Using kldload (Dynamically Loadable
Module)
To use a driver module in case LSI does not supply a driver module for your version of the FreeBSD OS, use the
procedures in this section. If you want to install only an LSI-supplied module, see
Section 6.6.3, Updating the
MegaRAID Kernel Driver Module in the FreeBSD OS .
Perform the following steps to compile the driver as a module:
1. Boot to the FreeBSD OS.
2. Obtain driver source files, see Section 6.2, Obtaining LSI FreeBSD Drivers .
3. Make sure your kernel is prepared for dynamically loadable module described in Section 6.6.1, Updating the
Kernel with the New Driver Source .
4. To build the driver module, type the following command, depending on which driver you use, and press Enter.
a. For the mfi driver, type the following commands and press Enter.
# cd /usr/src/sys/modules/mfi
# make
NOTE You can use only kldload to load the driver as a module if your boot drive is attached to the mother
board and is not managed by the MegaRAID controller.
