This article is very short and shallow. I mean... you can apply it to any architecture that Qemu supports (and there are many). Altogether there are 2 assembler instructions in the whole article. Not much of an exploration... Qemu usermode emulation is nice, but the full-hardware emulation is way more interesting. Eg. in https://github.com/dpc/titanos - toy kernel for Aarch64 written in our lord-and-saviour programming language: Rust, I use Qemu to run kernel and unittests for that kernel. With Qemu gdb stubs it's like having a software-defined hardware platform with a JTAG debugger attached. `make run` and it runs - no need to plug cables and press reset buttons. |
