使用三方Linux内核时需要移植的OpenHarmony补丁和需要打开的宏

详情：https://laval.csdn.net/64b5002155562f28498884a7.html?login=from_csdn

一、需要的OpenHarmony补丁

1、HDF patch

已有patch kernel/linux/patches/linux-5.10/common_patch/hdf.patch 可参考rk3568合入HDF patch

2、DFX patch

内核下源码位置: drivers/staging/hilog drivers/staging/hievent

3、Access Token patch安全增强

内核下源码位置: drivers/accesstokenid

其他文件有少量修改，主要看下面这连个链接合入： https://gitee.com/openharmony/kernel\_linux\_4.19/pulls/4 https://gitee.com/openharmony/kernel\_linux\_4.19/pulls/5

4、HMDFS 分布式文件系统

内核下源码位置:

fs/hmdfs

二、需要打开的宏

1、HDF相关的宏

CONFIG_DRIVERS_HDF=y CONFIG_HDF_SUPPORT_LEVEL=2 CONFIG_DRIVERS_HDF_PLATFORM=y CONFIG_DRIVERS_HDF_PLATFORM_GPIO=y CONFIG_DRIVERS_HDF_PLATFORM_I2C=y CONFIG_DRIVERS_HDF_INPUT=y CONFIG_DRIVERS_HDF_TP_5P5_GT911=y CONFIG_DRIVERS_HDF_SENSOR=y CONFIG_DRIVERS_HDF_SENSOR_ACCEL=y CONFIG_DRIVERS_HDF_SENSOR_ACCEL_BMI160=y CONFIG_DRIVERS_HDF_SENSOR_ACCEL_MXC6655XA=y CONFIG_DRIVERS_HDF_USB_PNP_NOTIFY=y CONFIG_DRIVERS_HDF_VIBRATOR=y CONFIG_DRIVERS_HDF_VIBRATOR_LINEAR=y CONFIG_DRIVERS_HDF_DSOFTBUS=y CONFIG_DRIVERS_HDF_LIGHT=y

更多HDF宏，可根据业务需要开启。
