FIXME: still having some x86 coupling. mm memory management unit proc process and synchronization model syscalls syscall interface:
x86 convention via int80. syscall nr in rax, up to 3 parameters in rdi, rsi,
rdx. Return value in rax EXTERN_SYM_PTR macro to declare a external symbol: cast its address into e.g. u64.
useful for getting the address of a tag in asm. print default print and println send output to both CGA and serial, CGA screen
synchronized and should NEVER be used in prologue.
use sprint! and sprintln! instead. println CGA screen println, synchronized. NEVER use in prologue sprint serial (0x3f8 for qemu) print, not synchronized. can use in prologue sprintln serial (0x3f8 for qemu) println, not synchronized. can use in prologue _entry ⚠ create_tasks 🔒
