1. OVERVIEW
|
|
|
|
The file iwlwifi-4965-2.ucode provided in this package must be
|
|
present on your system in order for the Intel Wireless WiFi Link
|
|
4965AGN driver for Linux (iwlwifi-4965) to operate on your system.
|
|
|
|
The "-2" in the filename reflects an interface/architecture version number.
|
|
It will change only when changes in new uCode releases make the new uCode
|
|
incompatible with earlier drivers.
|
|
|
|
On adapter initialization, and at varying times during the uptime of
|
|
the adapter, the microcode is loaded into the RAM on the network
|
|
adapter. The microcode provides the low level MAC features including
|
|
radio control and high precision timing events (backoff, transmit,
|
|
etc.) while also providing varying levels of packet filtering which can
|
|
be used to keep the host from having to handle packets that are not of
|
|
interest given the current operating mode of the device.
|
|
|
|
2. INSTALLATION
|
|
|
|
The iwlwifi-4965 driver will look for the file iwlwifi-4965-2.ucode using the
|
|
kernel's firmware_loader infrastructure. In order to function
|
|
correctly, you need to have this support enabled in your kernel. When
|
|
you configure the kernel, you can find this option in the following
|
|
location:
|
|
|
|
Device Drivers ->
|
|
Generic Driver Options ->
|
|
Hotplug firmware loading support
|
|
|
|
|
|
You can determine if your kernel currently has firmware loader support
|
|
by looking for the CONFIG_FW_LOADER definition on your kernel's
|
|
.config.
|
|
|
|
In addition to having the firmware_loader support in your kernel, you
|
|
must also have a working hotplug and udev infrastructure configured.
|
|
The steps for installing and configuring hotplug and udev are very
|
|
distribution specific.
|
|
|
|
Once you have the firmware loader in place (or if you aren't sure and
|
|
you just want to try things to see if it works), you need to install
|
|
the microcode file into the appropriate location.
|
|
|
|
Where that appropriate location is depends (again) on your system
|
|
distribution. You can typically find this location by looking in the
|
|
hotplug configuration file for your distro:
|
|
|
|
% grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent
|
|
|
|
This should give you output like:
|
|
|
|
FIRMWARE_DIR=/lib/firmware
|
|
|
|
If it lists more than one directory, you only need to put the
|
|
microcode in one of them. In the above example, installation is
|
|
simply:
|
|
|
|
% cp iwlwifi-4965-2.ucode /lib/firmware
|
|
|
|
You can now load the driver (see the INSTALL and README.iwlwifi provided with
|
|
the iwlwifi package for information on building and using that driver.)
