kernel event tracing

disk dynamically create/dev/directory under the device node, Further, you can notify other applications, the U disk device mount to the system, so that the dynamic support of the device. The position of uevent in kernel It can be concluded that the uevent mechanism is relatively simple, and the interface provided by Uevent is triggered when any device in the device model has an event to escalate. After th

The event Kernel Object in all kernel objects is the simplest one. It includes a count and two boolean values. A boolean value indicates whether an event is manually reset or automatically reset, and a Boolean value indicates whether the event is currently triggered. When a

These two days have been blocked by this problem. The VxWorks document does not mention how the root task of RTP of VxWorks receives the event from the kernel mode. The root Rask here refers to the task automatically generated after RTP spwan. It is said that some other companies also use this workaround method. Currently, WinDriver is helpless. First, we need to clarify one concept: RTP can only see

*, wait_queue_head_t *, struct poll_table_struct *); typedef struct POLL_TABLE_STRUCT { poll_queue_proc qproc; } poll_table; Contains a callback function that invokes the callback when the event is driven. Thus, the Epoll kernel implementation can be divided into two layers: the business layer and the driving layer. The business layer implements the functions of the Epoll and adds the new files
