@dark.ski dont forget the setup code

if(mmap(0, 65536, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_ANONYMOUS|MAP_FIXED, -1, 0) == MAP_FAILED) main(limit, base); // try again

@mothcompute
puts("balls");

@mothcompute console.log("Hello eorld!");

@max wait we need some setup code

typedef struct {void(*log)(char*);} c;
c console = {puts};

thats not very cross platform. what if i want to run it in ring 3

risipieces.bsky.social•1 day ago

my incredibly normal gpf handler that honors interrupt masking requests issued from ring 3

risipieces.bsky.social•1 day ago

it would be very funny to let userspace run hlt though. its so useless and honestly not even that harmful. i should put that in my kernel

at least in RISC-V you can WFI from S-mode (ring 3) safely (as in, M-mode [ring 0?] can impose a timeout)

risipieces.bsky.social•23 hours ago

even on x86 its fairly safe since the gpf handler can ensure some number of external interrupt sources are active before actually halting. the trouble is really just that all that time waiting could be spent running another program
