| 39 | bool "Include in-kernel firmware blobs in kernel binary" |
| 40 | depends on FW_LOADER |
| 41 | default y |
| 42 | help |
| 43 | The kernel source tree includes a number of firmware 'blobs' |
| 44 | which are used by various drivers. The recommended way to |
| 45 | use these is to run "make firmware_install" and to copy the |
| 46 | resulting binary files created in usr/lib/firmware directory |
| 47 | of the kernel tree to the /lib/firmware on your system so |
| 48 | that they can be loaded by userspace helpers on request. |
| 49 | |
| 50 | Enabling this option will build each required firmware blob |
| 51 | into the kernel directly, where request_firmware() will find |
| 52 | them without having to call out to userspace. This may be |
| 53 | useful if your root file system requires a device which uses |
| 54 | such firmware, and do not wish to use an initrd. |
| 55 | |
| 56 | This single option controls the inclusion of firmware for |
| 57 | every driver which usees request_firmare() and ships its |
| 58 | firmware in the kernel source tree, to avoid a proliferation |
| 59 | of 'Include firmware for xxx device' options. |
| 60 | |
| 61 | Say 'N' and let firmware be loaded from userspace. |

| 64 | string "External firmware blobs to build into the kernel binary" |
| 65 | depends on FW_LOADER |
| 66 | help |
| 67 | This option allows firmware to be built into the kernel, for the |
| 68 | cases where the user either cannot or doesn't want to provide it from |
| 69 | userspace at runtime (for example, when the firmware in question is |
| 70 | required for accessing the boot device, and the user doesn't want to |
| 71 | use an initrd). |
| 72 | |
| 73 | This option is a string, and takes the (space-separated) names of the |
| 74 | firmware files -- the same names which appear in MODULE_FIRMWARE() |
| 75 | and request_firmware() in the source. These files should exist under |
| 76 | the directory specified by the EXTRA_FIRMWARE_DIR option, which is |
| 77 | by default the firmware/ subdirectory of the kernel source tree. |
| 78 | |
| 79 | So, for example, you might set CONFIG_EXTRA_FIRMWARE="usb8388.bin", |
| 80 | copy the usb8388.bin file into the firmware/ directory, and build the |
| 81 | kernel. Then any request_firmware("usb8388.bin") will be |
| 82 | satisfied internally without needing to call out to userspace. |
| 83 | |
| 84 | WARNING: If you include additional firmware files into your binary |
| 85 | kernel image which are not available under the terms of the GPL, |
| 86 | then it may be a violation of the GPL to distribute the resulting |
| 87 | image -- since it combines both GPL and non-GPL work. You should |
| 88 | consult a lawyer of your own before distributing such an image. |

| 95 | This option controls the directory in which the kernel build system |
| 96 | looks for the firmware files listed in the EXTRA_FIRMWARE option. |
| 97 | The default is the firmware/ directory in the kernel source tree, |
| 98 | but by changing this option you can point it elsewhere, such as |
| 99 | the /lib/firmware/ directory or another separate directory |
| 100 | containing firmware files. |
