gbos.git - gbos - a tiny Unix-flavored OS for the Game Boy Color (kernel, shell, coreutils in C, RAM filesystem)

4 days	refactor: c/ -> usr/, compiled program blobs out of the source tree	user	1	-0/+0
	Userland sources live in usr/ (fits the Unix theme better than 'c'). SDCC output .bin blobs land in build/usr/ with the other build artifacts instead of littering the source dir; programs.asm INCBINs them from there. Byte-identical ROM.
6 days	kill + ps: implement SYS_KILL (pid 1 immortal) and a ps tool	user	1	-0/+10
	- PCB gains PROC_PROG (running program id), set by exec, inherited on fork. - sys_kill(pid): reject pid 1 (immortal) and unknown/dead pids; mark the target zombie, reparent its children to init, wake its parent if blocked in wait; schedule away if a process kills itself. Reuses FindPcbByPid/ReparentToInit. - sys_ps(slot,buf)->{pid,state,prog}; sys_progname(id) via NameTable reverse lookup. NameTable gains sh/ps/kill. - libc: kill/psget/progname; tools ps (pid state cmd) and kill <pid>. - verified: ps lists sh(B)+ps(R); kill 1 refused; kill 42 fails.
