Virtual memory, page tables, kmalloc() vs vmalloc() , the slab allocator, and reverse mappings.
At the heart of the kernel is the task scheduler. Linux treats both processes and threads as execution contexts, represented internally by the task_struct structure. linux kernel internals and development lfd420 pdf hot
Maps user-space virtual addresses to physical memory pages using page tables.

Never test experimental kernel modules on your primary workstation. Use a virtual machine (QEMU, VirtualBox, or KVM) configured for serial kernel debugging.
How does a computer go from BIOS/UEFI to a running Linux shell? This module covers the boot process, including the role of initrd and initramfs . For embedded developers, the lessons on are invaluable. Linux treats both processes and threads as execution
You learn that code is not abstract — it runs on metal with caches, DMA, and interrupts competing for attention. Your living room becomes a lab: BeagleBones, Raspberry Pis, and JTAG debuggers.
