①增加 IO 控制驱动

解压 IO 控制驱动压缩包：

io_zhouke.tar.gz

tarzxvfio_zhouke.tar.gzcpio_zhouke/*drivers/char/-avf

②增加 USB 相关支持

修改 arch/arm64/configs/rockchip_linux_defconfig：

CONFIG_USB_ACM=yCONFIG_USB_SERIAL_QT2=y

内核崩溃问题解决

只需要修改 arch/arm64/configs/rockchip_linux_defconfig 文件，注释掉以下内容即可（此修改包含第二部分 USB 支持）：

CONFIG_PSI=y98c98CONFIG_SCHED_RUNNING_AVG=y100c100CONFIG_SCHED_CORE_CTRL=y139c139<#CONFIG_SCHED_EAS=y--->CONFIG_SCHED_EAS=y4395c4395#CONFIG_USB_ACMisnotset4433c4433<#CONFIG_USB_DWC3_HOST=y--->#CONFIG_USB_DWC3_HOSTisnotset4511c4511#CONFIG_USB_SERIAL_QT2isnotset

所谓人尽其才，物尽其用，Linux 中 PSI 的目标就是让硬件资源的效能最大化。

②CONFIG_SCHED_RUNNING_AVG用于确定平均运行队列的调度程序接口。③CONFIG_SCHED_CORE_CTRLOpenHarmonyCPU 轻量级隔离特性介绍。 基本概念 CPU 轻量级隔离特性提供了根据系统负载和用户配置来选择合适的 CPU 进行动态隔离的能力。 内核会将被隔离 CPU 上的任务和中断迁移到其他合适的 CPU 上执行，被隔离的 CPU 会进入 ilde 状态，以此来达到功耗优化的目标。同时提供用户的配置和查询接口来实现更好的系统调优。 配置指导 使能 CPU 轻量级隔离特性：打开相关配置项及依赖。启用 CPU 轻量级隔离，需要通过编译内核时打开相应的配置项及依赖，相关 CONFIG 如下。④CONFIG_SCHED_EAS能量感知调度（EAS）使调度程序能够预测其决策对 CPU 消耗的电量的影响。 EAS 依赖于 CPU的能量模型 (EM) 来为每个任务选择省电的 CPU，同时要求对执行任务的吞吐量的影响最小。 EAS 仅在异构 CPU 架构上（例如 Arm big.LITTLE）上运行，因为这是通过调度器节省电量的效果最大的地方。

多模子系统服务加载错误

总结

经过以上修改之后，系统完全启动进入桌面之后，输入 power-shell setmode 602 命令，设置电源模式，防止系统重启，鼠标可正常工作。
