INSTALLATION 103. LICENSE 11 12 131. OVERVIEW 14 15The file iwlwifi-6000-4.ucode provided in this package must be 16present on your system in order for the Intel Wireless WiFi Link 17AGN driver for Linux (iwlagn) to operate on your system. 18 19The "-4" in the filename reflects an interface/architecture version number. 20It will change only when changes in new uCode releases make the new uCode 21incompatible with earlier drivers. 22 23On adapter initialization, and at varying times during the uptime of 24the adapter, the microcode is loaded into the memory on the network 25adapter. The microcode provides the low level MAC features including 26radio control and high precision timing events (backoff, transmit, 27etc.) while also providing varying levels of packet filtering which can 28be used to keep the host from having to handle packets that are not of 29interest given the current operating mode of the device. 30 312. INSTALLATION 32 33The iwlagn driver will look for the file iwlwifi-6000-4.ucode using the 34kernel's firmware_class infrastructure. More information can be found under 35Documentation/firmware_class in kernel source. In order to function 36correctly, you need to have this support enabled in your kernel. When 37you configure the kernel, you can find this option in the following 38location: 39 40 Device Drivers -> 41 Generic Driver Options -> 42 Userspace firmware loading support 43 44 45You can determine if your kernel currently has firmware loader support 46by looking for the CONFIG_FW_LOADER definition on your kernel's 47.config. 48 49In addition to having the firmware_class support in your kernel, you 50must also have a working udev and uevent infrastructure configured. 51The steps for installing and configuring udev are very 52distribution specific. 53 54Once you have the firmware loader in place (or if you aren't sure and 55you just want to try things to see if it works), you need to install 56the microcode file into the appropriate location. 57 58Where that appropriate location is depends (again) on your system 59distribution. You can typically find this location by looking in the 60udev scripts of your distro, the default is /lib/firmware. 61 62Installation of the firmware is simply: 63 64 % cp iwlwifi-6000-4.ucode /lib/firmware 65 66You can now load the driver (see the INSTALL and README.iwlwifi provided with 67the iwlwifi package for information on building and using that driver.) 68 693.
