| | | | | This article explores the world of random number generation in embedded systems, covering both pseudo-random number generators (PRNGs) and hardware-based random number generators (HRNGs). It explains their principles, provides examples of code, discusses their advantages and limitations, and highlights their applications in embedded systems. | |

| | | | | [AI summary] The article discusses the use of /dev/random and /dev/urandom in Linux systems for generating random numbers. It highlights that /dev/urandom is generally preferred over /dev/random due to its non-blocking nature and sufficient cryptographic security. The article also addresses misconceptions in the man pages and emphasizes that /dev/urandom is safe for most applications, including cryptographic uses, as long as the initial seeding is done properly. It mentions that while /dev/random is considered a legacy interface, it's not always necessary, and modern Linux distributions and syscalls like getrandom(2) provide better alternatives. | |

| | | There are many great tools that are useful for debugging the Linux kernel, including good old-fashioned printk, ftrace, and kgdb. In this post we'll be exploring how to use the kernel debugger (kgdb) to debug a QEMU VM, although some of the techniques below may be applied to debugging via hardware interfaces like JTAG. Using gdb as a front-end for the kernel debugger allows us to debug the kernel in the familiar and powerful debugging interface of gdb. | ||
