LINUX內核與驅動的最新編譯方法

驅動編譯有兩種方法：

1. 編譯到內核中

2. 編譯為獨立模塊

建立方法：

1)?在linux源碼樹的驅動目錄增加自己的驅動目錄，比如：現(xiàn)在新增一個網(wǎng)絡設備驅動

mkdir?linux_tree/drivers/net/poker_driver -p

cd?linux_tree/drivers/net/poker_driver

2) 編寫驅動源碼

vi??poker_drv_part1.c

vi??poker_drv_part2.c

vi??poker_drv_part3.c

3) 編寫源碼目錄Kconfig

vi Kconfig

config?POKER_DRV
tristate "poker_driver support"
default n
---help---
If you say Y here, the kernel will support poker_driver.
If you say M here, the kernel not support poker_driver, must perform "insmod poker_driver.ko".
If you say N here, the kernel not support?poker_driver.

4) 編寫源碼目錄Makefile

vi Makefile

obj-$(CONFIG_POKER_DRV) += poker_drv.o
poker_drv-objs += poker_drv_part1.o poker_drv_part2.o poker_drv_part3.o

5) 修改上級Kconfig

vi?linux_tree/drivers/net/Kconfig

source "drivers/net/poker_driver/Kconfig"

6) 修改上級Makefile

vi?linux_tree/drivers/net/Makefile

obj-$(CONFIG_POKER_DRV) +=?poker_driver/

7) 配置內核

make menuconfig

Device Drivers ?--->

[*] Network device support ?--->?

<>poker_driver?support

1. 編譯到內核中：

<*>poker_driver?support

linux_tree# make uImage

2. 編譯為獨立模塊

poker_driver?support?

linux_tree# make modules

括號問題：

[] ? 可選項 * 空

<> 可選項?* M?空
