help
The kernel source tree includes a number of firmware 'blobs'
that are used by various drivers. The recommended way to
use these is to run "make firmware_install", which, after
converting ihex files to binary, copies all of the needed
binary files in firmware/ to /lib/firmware/ on your system so
that they can be loaded by userspace helpers on request.
Various drivers in the kernel source tree may require firmware,
which is generally available in your distribution's linux-firmware
package.
The linux-firmware package should install firmware into
/lib/firmware/ on your system, so they can be loaded by userspace
helpers on request.
Enabling this option will build each required firmware blob
into the kernel directly, where request_firmware() will find
them without having to call out to userspace. This may be
useful if your root file system requires a device that uses
such firmware and do not wish to use an initrd.
specified by EXTRA_FIRMWARE into the kernel directly, where
request_firmware() will find them without having to call out to
userspace. This may be useful if your root file system requires a
device that uses such firmware and you do not wish to use an
initrd.
This single option controls the inclusion of firmware for
every driver that uses request_firmware() and ships its
firmware in the kernel source tree, which avoids a
every driver that uses request_firmware(), which avoids a
proliferation of 'Include firmware for xxx device' options.
Say 'N' and let firmware be loaded from userspace.
