Also added support for pipes and managed to integrate PicoTCP into the kernel (ran in userland before). I have a very limited BSD socket API layer right now, but I still managed to get a "telnet" server working.
Next up, porting dropbear 😎
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.
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
