Linux Device Driver Programming Lecture 34- Character driver file operation methods contd.
Character driver file operation methods contd. In the previous article, we came to know about how VFS and it's various data structures are involved in a file…
FSM Lecture 46- Run-to-completion(RTC) and QP™ framework
Run-to-completion(RTC) and QP™ framework The make an event code generates the event(it's an event producer code). And the event producer sends the event to the event dispatcher…
Linux Device Driver Programming Lecture 33- Character driver file operation methods
Character driver file operation methods In the previous article, we explored about the cdev_init() and cdev_add().We actually registered our character device using cdev, and the cdev structure…
FSM Lecture 45- Hierarchical State Machines(HSMs)
Hierarchical State Machines(HSMs) This article teaches about HSMs, which stands for Hierarchical state machines. In the previous article, we used the Flat state machine(FSM) approach for our…
FSM Lecture 44: Exercise-004 State table approach for implementation of an FSM part-4
Exercise-004 State table approach for implementation of an FSM part-4 Let's continue protimer_state_table_init coding. We just completed protimer_state_table_init function. Now, let's give the prototype of this function…
Linux Device Driver Programming Lecture 32- Character device registration contd.
Character device registration contd. In the previous article, we completed cdev_init(). Now, we have to register our cdev structure with kernels VFS, that is, the virtual file…
