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]({< ref “/posts/monolithic-vs-microkernel/” >}}), [Kernel Space vs User Space|Kernel and User Space interactions]({< ref “/posts/kernel-space-vs-user-space|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. [../../0-Inbox/syscalls|Syscalls]({< ref “/posts/../../0-inbox/syscalls|syscalls/” >}}): How system calls work, writing custom syscalls. [Kernel Synchronization in Linux|Kernel Synchronization]({< ref “/posts/kernel-synchronization-in-linux|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. ...
