编译步骤
首先下载并准备好内核源码
bash
sudo dnf download --source kernel
sudo dnf install rpm-build
rpm -ivh kernel-6.6.0-98.0.0.103.oe2403sp2.src.rpm
cd ~/rpmbuild/SPECS/
rpmbuild -bp kernel.spec安装必要的依赖和工具
bash
sudo dnf install asciidoc audit-libs-devel binutils-devel dwarves elfutils-devel elfutils-libelf-devel gtk2-devel java-1.8.0-openjdk java-1.8.0-openjdk-devel java-devel libbabeltrace-devel libcap-devel libcap-ng-devel libpfm-devel libtraceevent-devel libunwind-devel llvm-devel newt-devel numactl-devel pciutils-devel perl-generators xmlto修改内核设置
bash
cd ~/rpmbuild/BUILD/kernel-6.6.0/linux-6.6.0-98.0.0.103.riscv64
sudo cp /boot/config-6.6.0-98.0.0.103.oe2403sp2.riscv64 ./.config
sudo make olddefconfig
sudo make menuconfig此时会进入交互式编辑界面
选择需要构建的模块，joydev 模块导航到 Device Drivers -> Input device support -> Joystick interface，然后按下M，启用模块，然后保存配置。
编译并启用内核模块
bash
sudo make modules_prepare
sudo make M=drivers/input/
sudo cp drivers/input/joydev.ko /lib/modules/6.6.0-98.0.0.103.oe2403sp2.riscv64/kernel/drivers/input/
sudo depmod -a
sudo modprobe joydev查看手柄设备
bash
ls /dev/input/js*可以看到已经识别到了游戏手柄设备
/dev/input/js0
