[OS Project] Chap10-1. Process - PCB and Context switch
ProcessA process is an instance of an application. Each process has its own independent execution context and resources, such as a virtual address space. Practical operating systems provide the execution context as a separate concept called a "thread". For simplicity, in this book we'll treat each process as having a single thread. Process control block The following process structure defines ..

[OS Project] Chap9. Memory Allocation
Memory AllocationBefore implementing a memory allocator, let's define the memory regions to be managed by the allocator . = ALIGN(4); . += 128 * 1024; /* 128KB */ __stack_top = .; . = ALIGN(4096); __free_ram = .; . += 64 * 1024 * 1024; /* 64MB */ __free_ram_end = .;} This adds two new symbols, __free_ram and __free_ram_end. This defines a memory area after the stack space. ..

[OS Project] Chap8. Exception
ExceptionException is a CPU feature that allows the kernel to handle various events, such as invalid memory access (aka. page faults), illegal instructions, and system calls. Exception is like a hardware-assisted try-catch mechanism in C++ or Java. Until CPU encounters the situation where kernel intervention is required, it continues to execute the program. The key difference from try-catch is ..

[OS Project] Chap7. Kernel Panic
Kernel PanicA kernel panic occurs when the kernel encounters an unrecoverable error, similar to the concept of panic in Go or Rust. Have you ever seen a blue screen on Windows? Let's implement the same concept in our kernel to handle fatal errors. The following PANIC macro is the implementation of kernel panic#define PANIC(fmt, ...) \ do ..

[OS Project] Chap6. C Standard Library
C Standard LibraryIn this chapter, let's implement basic types and memory operations, as well as string manipulation functions. In this book, for the purpose of learning, we'll create these from scratch instead of using C standard library. The concepts introduced in this chapter are very common in C programming, so ChatGPT would provide solid answers. If you struggle with implementation or under..
