@prologic@twtxt.net I’d love to take a look at the code. 😅

I’m kind of curious to know how much Assembly I need vs. How much of a microkernel can I build purely in Mu (µ)? 🤔

Can’t really answer that, because I only made a working kernel for 16-bit real mode yet. That is 99% C, though, only syscall entry points are Assembly. (The OpenWatcom compiler provides C wrappers for triggering software interrupts, which makes things easier.)

But in long mode? No idea yet. 😅 At least changing the page tables will require a tiny little bit of Assembly.

@prologic@twtxt.net That might be a challenge, at least in 16-bit Real Mode: The OS follows the model of COM files on DOS, i.e. the size of the binary cannot exceed 64 KiB and heap+stack of the running program will have to fit into that same 64 KiB. 😅 (The memory layout is very rigid, each process gets such a 64 KiB slice.)

And in 64-bit Long Mode, there is no “kernel” yet. The thing in the video is literally just a small bare-metal program.

But some day, maybe. 😃

My little toy operating system from last year runs in 16-bit Real Mode (like DOS). Since I’ve recently figured out how to switch to 64-bit Long Mode right after BIOS boot, I now have a little program that performs this switch on my toy OS. It will load and run any x86-64 program, assuming it’s freestanding, a flat binary, and small enough (< 128 KiB code, only uses the first 2 MiB of memory).

Here I’m running a little C program (compiled using normal GCC, no Watcom trickery):

https://movq.de/v/b27ced6dcb/los86%2D64.mp4

Next steps could include:

• Use Rust instead of C for that 64-bit program?
  
• Provide interrupt service routines. (At the moment, it just keeps interrupts disabled.)
