As you know, I’ve done a lot of OpenBMC builds on my AMD Ryzen desktop PC, as well as my Surface Pro 6. I decided to tackle the same builds on Amazon Web Services (AWS), on virtual machines based on the Intel Cascade Lake CPU, as well as the AMD EPYC 7000. Which one is faster and cheaper?

Do you know how it feels when you have an itch, and you just have to scratch it? Well, after an extended hiatus from writing, I felt an overwhelming compulsion to do another MinnowBoard image build with source and symbols, do some more exploring, and then blog about it.

In Episode 41, Hacking the Linux Kernel, Part 2, I successfully hacked the Linux kernel, both on a native Linux partition, and within a Ubuntu VM on VirtualBox, by using the general directions within the Linux Newbies First Kernel Patch tutorial. This week, I worked towards hacking the Linux kernel using a Yocto-based qemux86 on VirtualBox, as a final step towards actually hacking the kernel on my MinnowBoard.
