Subject: Firmware loading with static kernel and initramfs
Date: Sun, 29 Jun 2014 18:15:15 +0100 [thread overview]
Message-ID: <53B049A3.7000803@dpets.co.uk> (raw)
There seems to be a general problem when using a static kernel and
initramfs in that the wireless drivers try to load firmware before the
disks are mounted and the /lib/firmware folder is available. Various
people seem to have come across problems with firmware not loading, some
of which seem to relate to this problem, which they have approached as
if it is a problem with their particular driver. However it seems to be
a general problem and I have had it with three different drivers.
There seems to be a number of possible approaches to this: loading the
firmware in an initramfs; changing the sequence in which wireless
drivers start so that they wait until the disks are mounted; compiling
the firmware into the kernel and loading the firmware as part of ifup.
I see that the latter has been done for one driver
(http://thread.gmane.org/gmane.linux.kernel.wireless.general/3390).
What is the current situation with this problem and what needs doing?
