1. Overview
#############################################################################

This package contains Linux driver code for HighPoint RocketRAID 2640/2642
SATA controller. You can use it to build the driver module for custom
Linux kernels.

2. Build the driver as a kernel module
#############################################################################

NOTE: The latest tested kernel version: {LINUX_VERSION}.

1) Install kernel build tools (gcc, binutils, make, etc.)

2) Setup the kernel source/headers

To build driver modules for a specific kernel, you shall use same
configuration for the kernel and the driver. Otherwise, the driver may
be unable to load, or behave abnormally.

- For Linux kernel 2.6 -

On most distributions based on kernel 2.6, an exploded source tree is not
required to build a driver against the currently in-use kernel. As long
as the system has kernel headers setup under /lib/modules/`uname -r`/build,
you can simply run "make" to build the driver.

If you want to build the driver against a custom kernel source, you must
setup the kernel source manually and run "make" under kernel source tree
to setup kernel headers.

- For Linux kernel 2.4 -

You need a full kernel source tree to build the driver. If you are building
a driver for the currently in-use kernel, the kernel source should match
the version of the running kernel. In addition, you must obtain the config
file for the running kernel:

For Red Hat or Fedora Linux, you can find the stock kernel config files
under {kernel-source-dir}/configs, named kernel-*.config. Select the one
matches your hardware and copy it to {kernel-source-dir}/.config.

For SuSE Linux, the config files for current kernel is under /boot dir
so you can the kernel source by

# cd /usr/src/linux-{kernel-version}.SuSE
# cp /boot/vmlinuz.config .config
# cp /boot/vmlinuz.version.h include/linux/version.h
# cp /boot/vmlinuz.autoconf.h include/linux/autoconf.h

For other distributions please refer to the distribution documents to
obtain the config file.

If you are building a custom kernel and a driver, you can setup the kernel
config by yourself, using "make config" or "make menuconfig" commands
under kernel source directory.

Once the kernel config file is ready, run following commands under kernel
source directory to setup kernel headers:

# make oldconfig
# make dep

On some Red Hat versions, {kernel-source-dir}/include/linux/modversions.h
may be incorrect after "make dep", you need check if there is a line
"#include " before "#include " in that
file. If not, please add the line manually.

3) Build the driver

After you have configured the kernel source/headers you can build the driver
by following commands (assume you have extracted the driver source under
directory rr2640-linux-src-v1.xx):

# cd rr2640-linux-src-v1.xx/product/rr2640/linux/
# make

You can append below options to "make" command:

KERNELDIR=...
Specify kernel source directory. If not specified the driver will
use /lib/modules/{kernel-version}/build/ as the default location.
This option is needed if you have a manually configured kernel
source tree.

CROSS_COMPILE=...
Specify cross compiler prefix.

ARCH=...
Specify target system machine architecture.
Currently only i386 and x86_64 is supported.

4) Install/upgrade the driver

If you are building driver for currently in-use kernel you can use
"make install" to install or upgrade the driver:

# cd rr2640-linux-src-v1.xx/product/rr2640/linux/
# make install

The KERNELDIR=... parameter may be required, e.g.

# make install KERNELDIR=/usr/src/linux-2.6

"make install" command will copy the driver module to the directory
/lib/modules/`uname -r`/kernel/drivers/scsi, and update the initrd file
if it contains an old version driver.

If your system is installed on the controller, a reboot is required
to make the new driver take effect.

Please note "make install" may not work on some distributions. In that
case you have to install the driver manually.

After the driver is installed, it can be loaded manually by

# modprobe rr26xx

To load the driver automatically during system startup, you can either
put it into initrd file or configure a /etc/rc.d script to load it.


#############################################################################
3. Using the driver as a kernel patch
#############################################################################

You must have a full kernel source tree to use the driver as a patch.
To patch a kernel source tree, run the command

# cd rr2640-linux-src-v1.xx/product/rr2640/linux/
# make patchkernel KERNELDIR=

For an unconfigured 2.6 kernel source tree, include/linux/version.h may
not exist so you should add "KERNEL_VER=2.6" to the command:

# make patchkernel KERNELDIR= KERNEL_VER=2.6

Then you can configure the driver into kernel during the kernel
configuration process (e.g. "make menuconfig"). It is listed under
scsi low level drivers.

Below is an example to make and install a kernel with the driver built-in:

# cd /usr/src/linux-2.6.24
# make menuconfig

Select "Device Drivers --->" and press enter.
Select "SCSI device support", then press 'Y' to make it built-in.
Select "SCSI disk support" then press 'Y' to make it build-in.
Select "SCSI low-level drivers --->" and press enter.
Select "HighPoint RocketRAID 26xx support" and press 'Y'.
Exit and save the kernel configuration.

# make
# make modules_install
# make install

Then you can reboot from the new kernel.
