BUGS/TODO

Some bugs/TODO items. See also egrep -rI 'BUG|TODO' src

  • Some exceptions are raised with CS set to something other than kernel (0x8), which should not happen. Continued exection at this point would cause a GPF.

    see cpu.c:trap_handler()

  • (following thoughts from above..) What are the correct segment selectors for kernel code and data segments? We seem to use or come across 0x8, 0x10 (16h), 0x12 (18h). Confirm that we are using the correct ones in places such as GDT/IDT setup, and trap handling.
