For some reason it also amuses me greatly that MacOS defaults to "Lukass-iMac" as name. So elegant™.

Xelix news: Managed to fix the PCI issues I've been having (by making PCI interrupts non-reentrant for now), wrote a driver for Ne2000 NICs and hooked that up to PicoTCP.

Suddenly: Internet! Next up, figuring out how to expose all this properly as BSD sockets in userland.

🤔

Added the unlink() syscall. 😈 Delete everything! #osdev #xelix

Probably related to another issue where any PCI interrupt will cause mysterious triple faults. Which is very frustrating since I recently ported the PicoTCP stack, but now have no way of getting packets into it… #osdev

Tried booting Xelix in VirtualBox for the first time in ages. Looks like it's not very happy with the new interrupt handling. I think it fires a nested interrupt right after initialization where QEMU doesn't, and that triggers one of the several reentrancy issues still scattered throughout the code. #osdev

(90% of the userland is still busybox right now. I've been meaning to port the coreutils but other stuff keeps coming up).

In related news, spent a lot of time making context switching more stable and improving the ext2 driver recently. Ported pciutils/lspci earlier today and it's starting to feel like a real UNIX™. #osdev

I guess this will now officially™ become the place I spam about my osdev hackery.
