BSP Topics
1. Linux Kernel Internals Importance: Understanding kernel internals is crucial for BSP and driver development as it helps in debugging, optimizing performance, and modifying the kernel to meet hardware-specific requirements. Topics: Kernel Architecture: Monolithic vs Microkernel, Kernel and User Space interactions. Process Management: Understanding task_struct, process states, scheduling algorithms. Interrupt Handling: SoftIRQs, tasklets, bottom halves, handling IRQs efficiently. Memory Management: Paging, kmalloc/vmalloc, slab allocator, ARM MMU and memory regions. Syscalls: How system calls work, writing custom syscalls. Kernel Synchronization: Spinlocks, mutexes, semaphores, barriers, RCU. Workqueues and Timers: Deferred execution, using timers for scheduling tasks. 2. Linux Device Drivers Importance: Device drivers are the bridge between hardware and the OS. Understanding drivers is crucial for embedded systems and BSP development. ...
