Note, this driver is not stable at the moment, therefore use of the driver from the SCST tree is recommended.

Find out whether you will need iSCSI zero-copy optimization. Since it is valuable only with scst_user user space dev handlers, most likely, you don't need this feature. If you don't, skip the kernel download, patch, rebuild
and reboot steps and continue with the <a href="#blacklist">SCST build step</a>.
</li>
<li>Decide whether you want to start from a vanilla Linux kernel source tree
or from the kernel source tree specific to your Linux distribution. Vanilla kernel sources can be downloaded from <a href="http://www.kernel.org/pub/linux/kernel/">http://www.kernel.org/pub/linux/kernel/</a>. Unzip the downloaded archive under /usr/src:
<pre>[root@proj ]# cd /usr/src
[root@proj src ]# tar -xjf /usr/src/linux-3.11.8.tar.bz2</pre>
Instructions for obtaining a distribution-specific kernel source tree vary. An example for Debian:
<pre>[root@proj src ]# apt-get install linux-source-`uname -r`
[root@proj src ]# tar xjf linux-source-`uname -r`.tar.bz2</pre>
</li>
<li>The next step is to configure the kernel:
<pre>[root@proj linux ]# pwd
/usr/src/linux
[root@proj linux ]# make menuconfig</pre>
If you have built a 32-bit kernel make sure to disable HIGHMEM4G and
HIGHMEM64G, i.e.
<pre>[root@proj linux ]# grep -i highmem .config
CONFIG_NOHIGHMEM=y
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set</pre>
If you have built a 32-bit kernel on a system with more than 1GB of memory,
consider to change CONFIG_VMSPLIT option to an appropriate value.
</li>
<li>Next, build and install the kernel:
<pre>[root@proj linux ]# make -j$(ls -1d /sys/devices/system/cpu/cpu[0-9]* | wc -l) bzImage modules
[root@proj linux ]# make modules_install install</pre>
</li>
<li>
Reboot the system and during boot select the freshly built kernel to boot from.

Unload the qla2xxx kernel module provided by your Linux distribution and blacklist it:
