Select this option if you don't have magic firmware for drivers that

need it.

If unsure, say Y.

Say yes to avoid building firmware. Firmware is usually shipped
|
|
with the driver, and only when updating the firmware a rebuild
|
|
should be made.
|
|
If unsure say Y here.

---help---

This option is provided for the case where no in-kernel-tree modules

require userspace firmware loading support, but a module built outside
|
|
the kernel tree does.

help
|
|
The kernel source tree includes a number of firmware 'blobs'
|
|
which are used by various drivers. The recommended way to
|
|
use these is to run "make firmware_install" and to copy the
|
|
resulting binary files created in usr/lib/firmware directory
|
|
of the kernel tree to the /lib/firmware on your system so
|
|
that 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 which uses
|
|
such firmware, and do not wish to use an initrd.
|
|
|
|
This single option controls the inclusion of firmware for
|
|
every driver which uses request_firmware() and ships its
|
|
firmware in the kernel source tree, to avoid a proliferation
|
|
of 'Include firmware for xxx device' options.
|
|
|
|
Say 'N' and let firmware be loaded from userspace.
|
|
|
|
config EXTRA_FIRMWARE
|
|
string "External firmware blobs to build into the kernel binary"
|
|
depends on FW_LOADER
|
|
help
|
|
This option allows firmware to be built into the kernel, for the
|
|
cases where the user either cannot or doesn't want to provide it from
|
|
userspace at runtime (for example, when the firmware in question is
|
|
required for accessing the boot device, and the user doesn't want to
|
|
use an initrd).
|
|
|
|
This option is a string, and takes the (space-separated) names of the
|
|
firmware files -- the same names which appear in MODULE_FIRMWARE()
|
|
and request_firmware() in the source. These files should exist under
|
|
the directory specified by the EXTRA_FIRMWARE_DIR option, which is
|
|
by default the firmware/ subdirectory of the kernel source tree.
|
|
|
|
So, for example, you might set CONFIG_EXTRA_FIRMWARE="usb8388.bin",
|
|
copy the usb8388.bin file into the firmware/ directory, and build the
|
|
kernel. Then any request_firmware("usb8388.bin") will be
|
|
satisfied internally without needing to call out to userspace.
|
|
|
|
WARNING: If you include additional firmware files into your binary
|
|
kernel image which are not available under the terms of the GPL,
|
|
then it may be a violation of the GPL to distribute the resulting
|
|
image -- since it combines both GPL and non-GPL work. You should
|
|
consult a lawyer of your own before distributing such an image.

|
|
help
|
|
This option controls the directory in which the kernel build system
|
|
looks for the firmware files listed in the EXTRA_FIRMWARE option.
|
|
The default is the firmware/ directory in the kernel source tree,
|
|
but by changing this option you can point it elsewhere, such as
|
|
the /lib/firmware/ directory or another separate directory
|
|
containing firmware files.

Say Y here if you want the Driver core to produce a bunch of

|
debug messages to the system log. Select this if you are having a
|
|
problem with the driver core and want to see more of what is

going on.

If you are unsure about this, say N here.
