TODO

Implement

  • Virtual Filesystem

  • Ramdisk (initrd)

  • Ext2 filesystem or similar

  • Paging

  • Elf parsing (and relocation)

  • User processes

  • System calls

Fix

  • Implement a real scheduling algorithm (currently FIFO)

  • Use the APIC (cpu-local timer) in one-shot mode to wake up sleeping threads, rather than walking the entire sleep-queue on each all to schedule()

  • Implement malloc/free myself rather than use bget (I could easily port a simple malloc implementation I wrote not too long ago)

  • Calibrate the PIT before using it.

  • Fix date/time issue present on Bochs (but not QEMU)

  • Assess the impact of drift when using the PIT (at 100Hz)

  • Verify that I'm delaying long enough when reading/writing keyboard and CMOS ports... (I only read when interrupts are triggered, so...)
