Now that you have the name of the firmware file that you want, it’s relatively easy to identify the package that provides the required file.
How do I find and install the missing firmware? You have the option to supply the missing files on a USB stick (either directly or through the corresponding package). The Debian installer also detects when you have hardware that might require a missing firmware file. W: Possible missing firmware /lib/firmware/e100/d101m_ucode.bin for module e100 W: Possible missing firmware /lib/firmware/e100/d101s_ucode.bin for module e100 W: Possible missing firmware /lib/firmware/e100/d102e_ucode.bin for module e100 Update-initramfs: Generating /boot/initrd.img-2.6.32-5-amd64 Update-initramfs will also generate a similar warning on the terminal: If one (or more) of those firmware is (are) not yet available on the system, you will get a warning message similar to this one: This information can be retrieved with modinfo: When you install a new version of the Linux kernel with the official Debian packages, the post-installation script will go through all loaded modules (those listed by lsmod) and it will verify whether this module as provided by the newly installed kernel might require firmware files. They look like this:Į100: eth0: e100_request_firmware: Failed to load firmware "e100/d101m_ucode.bin": -2īut you might be informed sooner. How do I know whether I need a firmware?įirst of, you can notice messages from the kernel telling you that it tried to load a firmware but it failed.
It looks into the following directories:įirmware provided by packages are thus usually in /lib/firmware and you can use /usr/local/lib/firmware for manually installed firmware. Where are firmware stored?įirmware.agent is a simple shell script that tries to locate a firmware before sending it back to the kernel through a sysfs entry. udev is getting the request with the name of the firmware, and in its default configuration (see /lib/udev/rules.d/les) it executes /lib/udev/firmware.agent in response. Thus when the kernel needs a firmware, it sends out a request to user-space. Thanks to this standardization, it’s possible to either embed the firmware in the kernel or to have it request the firmware from user-space when needed.ĭebian (like most distributions) has selected the latter option.

In the Linux kernel, the drivers are all using a standardized interface (request_firmware) to retrieve the firmware before sending it to the device.

The driver for that hardware typically loads the firmware on the device as part of its initialization. What are firmware and how are they used?įrom the user’s point of view, a firmware is just some data that is needed by some piece of hardware in order to function properly. I’m thus going to do a small overview on the topic and teach you what you need to know to deal with the problem. This will cause some troubles to users who need them. You know it already, since Debian 6.0 non-free firmware are no longer provided by a standard Debian installation.
