1. 控制打开哪些模块的Log
/sys/module/camera/parameters/debug_mdl
具体的模块定义在：techpack/camera/drivers/cam_utils/cam_debug_util.h
/* Module IDs used for debug logging */ #define CAM_CDM (1 << 0) #define CAM_CORE (1 << 1) #define CAM_CPAS (1 << 2) #define CAM_ISP (1 << 3) #define CAM_CRM (1 << 4) #define CAM_SENSOR (1 << 5) #define CAM_SMMU (1 << 6) #define CAM_SYNC (1 << 7) #define CAM_ICP (1 << 8) #define CAM_JPEG (1 << 9) #define CAM_FD (1 << 10) #define CAM_LRME (1 << 11) #define CAM_FLASH (1 << 12) #define CAM_ACTUATOR (1 << 13) #define CAM_CCI (1 << 14) #define CAM_CSIPHY (1 << 15) #define CAM_EEPROM (1 << 16) #define CAM_UTIL (1 << 17) #define CAM_HFI (1 << 18) #define CAM_CTXT (1 << 19) #define CAM_OIS (1 << 20) #define CAM_RES (1 << 21) #define CAM_MEM (1 << 22) #define CAM_IRQ_CTRL (1 << 23) #define CAM_REQ (1 << 24) #define CAM_PERF (1 << 25) #define CAM_CUSTOM (1 << 26) #define CAM_PRESIL (1 << 27) #define CAM_OPE (1 << 28) #define CAM_IO_ACCESS (1 << 29) #define CAM_SFE (1 << 30)
举例：
echo 0x20008 > /sys/module/camera/parameters/debug_mdl
2. 控制debug type
表示日志是打印在log里面，还是打印在trace里面：/sys/module/camera/parameters/debug_type
- 0x0 - only logs
- 0x1 - only trace
- 0x2 - logs + trace
