Covers memory paging mechanisms for address translation. Explains page tables with page table entries (PTEs), multi-level page tables for space efficiency, translation lookaside buffer (TLB) for caching translations, page faults, and integration with virtual memory swapping.
Details xv6 process management implementation. Covers struct proc (PCB in xv6), page table for virtual-to-physical address mapping, kernel stack for system calls, file descriptor table for open files, and process table (ptable) structure.
Introduces process abstraction and management. Covers process definition, states (running, ready, blocked), process control block (PCB), CPU scheduler, context switching, state transitions, and system booting from BIOS through bootloader to kernel.
Introduction to xv6 teaching operating system for x86. Covers x86 assembly language basics including registers (eax, ebx, eip, esp, ebp), instructions (mov, push, pop, jmp, call, ret), function call mechanics, and caller/callee save register conventions.
Introduction to virtualization and cloud computing. Covers hypervisor/VMM basics, trap-and-emulate technique, x86 privilege rings, Popek-Goldberg theorem, paravirtualization (Xen), full virtualization (VMware), and hardware-assisted virtualization (KVM/QEMU) for x86 architecture.
