| config STANDALONE |
| bool "Select only drivers that don't need compile-time external firmware" if EXPERIMENTAL |
| default y |
| help |
| Select this option if you don't have magic firmware for drivers that |
| need it. |
| |
| If unsure, say Y. |
| |
| config PREVENT_FIRMWARE_BUILD |
| bool "Prevent firmware from being built" |
| default y |
| help |
| 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. |
| |
| config FW_LOADER |
| tristate "Userspace firmware loading support" if EMBEDDED |
| depends on HOTPLUG |
| default y |
| ---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. |
| |
| config FIRMWARE_IN_KERNEL |
| bool "Include in-kernel firmware blobs in kernel binary" |
| depends on FW_LOADER |
| default y |
| 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 usees request_firmare() 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. |
| |
| config EXTRA_FIRMWARE_DIR |
| string "Firmware blobs root directory" |
| depends on EXTRA_FIRMWARE != "" |
| default "firmware" |
| 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. |
| |
| config DEBUG_DRIVER |
| bool "Driver Core verbose debug messages" |
| depends on DEBUG_KERNEL |
| help |
| 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. |
| |
| config DEBUG_DEVRES |
| bool "Managed device resources verbose debug messages" |
| depends on DEBUG_KERNEL |
| help |
| This option enables kernel parameter devres.log. If set to |
| non-zero, devres debug messages are printed. Select this if |
| you are having a problem with devres or want to debug |
| resource management for a managed device. devres.log can be |
| switched on and off from sysfs node. |
| |
| If you are unsure about this, Say N here. |
