1 menu "Generic Driver Options"
3 config UEVENT_HELPER_PATH
4 string "path to uevent helper"
6 default "/sbin/hotplug"
8 Path to uevent helper program forked by the kernel for
12 bool "Select only drivers that don't need compile-time external firmware" if EXPERIMENTAL
15 Select this option if you don't have magic firmware for drivers that
20 config PREVENT_FIRMWARE_BUILD
21 bool "Prevent firmware from being built"
24 Say yes to avoid building firmware. Firmware is usually shipped
25 with the driver, and only when updating the firmware a rebuild
30 tristate "Userspace firmware loading support"
33 This option is provided for the case where no in-kernel-tree modules
34 require userspace firmware loading support, but a module built outside
38 string "External firmware blobs to build into the kernel binary"
41 This option allows firmware to be built into the kernel, for the
42 cases where the user either cannot or doesn't want to provide it from
43 userspace at runtime (for example, when the firmware in question is
44 required for accessing the boot device, and the user doesn't want to
47 This option is a string, and takes the (space-separated) names of the
48 firmware files -- the same names which appear in MODULE_FIRMWARE()
49 and request_firmware() in the source. These files should exist under
50 the directory specified by the EXTRA_FIRMWARE_DIR option, which is
51 by default the firmware/ subdirectory of the kernel source tree.
53 So, for example, you might set CONFIG_EXTRA_FIRMWARE="usb8388.bin",
54 copy the usb8388.bin file into the firmware/ directory, and build the
55 kernel. Then any request_firmware("usb8388.bin") will be
56 satisfied internally without needing to call out to userspace.
58 WARNING: If you include additional firmware files into your binary
59 kernel image which are not available under the terms of the GPL,
60 then it may be a violation of the GPL to distribute the resulting
61 image -- since it combines both GPL and non-GPL work. You should
62 consult a lawyer of your own before distributing such an image.
64 config EXTRA_FIRMWARE_DIR
65 string "Firmware blobs root directory"
66 depends on EXTRA_FIRMWARE != ""
69 This option controls the directory in which the kernel build system
70 looks for the firmware files listed in the EXTRA_FIRMWARE option.
71 The default is the firmware/ directory in the kernel source tree,
72 but by changing this option you can point it elsewhere, such as
73 the /lib/firmware/ directory or another separate directory
74 containing firmware files.
77 bool "Driver Core verbose debug messages"
78 depends on DEBUG_KERNEL
80 Say Y here if you want the Driver core to produce a bunch of
81 debug messages to the system log. Select this if you are having a
82 problem with the driver core and want to see more of what is
85 If you are unsure about this, say N here.
88 bool "Managed device resources verbose debug messages"
89 depends on DEBUG_KERNEL
91 This option enables kernel parameter devres.log. If set to
92 non-zero, devres debug messages are printed. Select this if
93 you are having a problem with devres or want to debug
94 resource management for a managed device. devres.log can be
95 switched on and off from sysfs node.
97 If you are unsure about this, Say N here.
