Toby Jaffey	e07eeab043	Make yield a regular syscall taking an argument. ... Allows "wait for interrupt"/"wait for event" type operation where VM code blocks until the host has something for it.	2025-12-10 10:35:18 +00:00
Toby Jaffey	76fba39a21	Rework syscall ABI. ... Syscalls now accept two parameters, allowing for things like "int count = read(buf, len)" Rather than providing safe signatures for syscalls, the user is now given helper functions to safely parse incoming values, c-strings and slices.	2025-12-09 21:51:35 +00:00
