This is great. I find the x86_64 paging to be very similar to RISC V which I was exposed to poring through xv6 code.

- snvzz 3y agoThere's definitely both "established best practices" and many other legacy ways to do things on x86. RISC-V is quite boring, majorly opting for well-proven approaches. And a lot of its technical value comes from doing just that. Yet x86-64 and ARM would have a hard time justifying their complexity, when RISC-V achieves the same with simplicity, and matches or beats them on objective metrics[0]. 0. https://dl.acm.org/doi/pdf/10.1145/3624062.3624233 https://dl.acm.org/doi/pdf/10.1145/3624062.3624233
