The perfect emulation setup to study and develop the Linux kernel v5.4.3, kernel modules, QEMU, gem5 and x86_64, ARMv7 and ARMv8 userland and baremetal assembly, ANSI C, C++ and POSIX. GDB step debug and KGDB just work. Powered by Buildroot and crosstool-NG. Highly automated. Thoroughly documented. Automated tests. "Tested" in an Ubuntu 24.04 host.
We currently just set argc to 0 on the bootloaders before calling main. This is particularly interesting because we can run several userland examples on baremetal.
This mechanism would be analogous to kernel CLI parameters and DTB, and would therefore allow us to have a single binary that works on either QEMU or gem5, just like the Linux kernel does! We just have to pass CLI arguments that describe the hardware!

Maybe this will be easy on QEMU with
-device loaderwhich according to docs supports direct data memory mapping: https://github.com/qemu/qemu/blob/60905286cb5150de854e08279bca7dfc4b549e91/docs/generic-loader.txtThis mechanism would be analogous to kernel CLI parameters and DTB, and would therefore allow us to have a single binary that works on either QEMU or gem5, just like the Linux kernel does!
