P.S.
(1) The display of time since boot is located in lower-right corner;
(2) The display of the last pressed glyph is located in lower-left corner.
The provided Makefile:
1) builds a kernel
2) copies it into rootfs/boot/kernel/kernel
3) creates an ISO CD image with the rootfs/ contents
To boot the system in QEMU, run:
qemu-system-x86_64 -curses -cdrom $USER.iso -drive id=disk,file=$USER.img,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0 -net nic -net user,hostfwd=tcp::10080-:80 -net user,hostfwd=tcp::10023-:23 --no-reboot -gdb tcp::9998
Explanation of parameters:
-curses use a text console (omit this to use default SDL/VNC console)
-cdrom x.iso connect a CD-ROM and insert CD with x.iso disk
--no-reboot exit when guest reboots
-gdb tcp::9998 listen for "remote" debugging connections on port 9998
connect a hard drive with x.img disk:
-drive id=disk,file=$USER.img,if=none -device ahci,id=ahci -device ide-drive,drive=disk,bus=ahci.0
connect a NIC and forward local port 10080 into port 80 and local port 10023 to port 23
-net nic -net user,hostfwd=tcp::10080-:80 -net user,hostfwd=tcp::10023-:23
When using the -curses mode, switch to the qemu> console with ESC-2.
To connect a remote debugger to the running qemu VM:
gdb ./kernel
target remote localhost:9998
