Check out a review if you're interested. Contents theory index Lecture Notes As you well know, the CPU - Central Processing Unit - is the brain of all of our contemporary -- so-called smart -- devices: PCs, laptops, mobile phones, TVs, cars, and now they're even present in our household appliances such as fridges and microwaves (with questionable utility). But how (and what) are they made (of)? How do the… text/html 2023-07-24T13:49:23+03:00 http://ocw.cs.pub.ro/courses/ass/cursuri/02?rev=1690195763&do=diff 02 - Bootstrapping Linux Contents theory index Lecture Notes Initial ramdisk & rootfs When Linux tries to boot into User Space, it does so by starting the init (PID=1) process from several well-known locations (e..g: /usr/sbin/init, etc.) For this to happen, the kernel first needs to load a root filesystem. The location of this rootfs is specified as part of the kernel's command line arguments: text/html 2023-07-24T13:49:29+03:00 http://ocw.cs.pub.ro/courses/ass/cursuri/03?rev=1690195769&do=diff 03 - Trusted Execution Contents theory index Lecture Notes In the cyber security landscape, as you well know, any piece of software may contain various security vulnerabilities (usually, due to its developers' negligence), which may allow a malicious entity to obtain execution privileges on the device. text/html 2024-08-09T15:00:33+03:00 http://ocw.cs.pub.ro/courses/ass/cursuri/04?rev=1723204833&do=diff 04 - Kernel development Contents theory index Lecture Notes In these lecture notes we're going to discuss how to set up a virtual development environment and the difference between using an emulator (i.e., QEMU-system) and a simulator (i.e., ARM's FVP). This should get you all set up for doing some kernel development or enabling you to solve the previous three labs even without access to a development board.
