tl;dr:
control io ports or something?

another weird, architecture specific syscall. this time for i386

truly the sign of a high quality syscall!

i don't really have much to say about these, so maybe we can just discuss CAP_SYS_RAWIO instead. capabilities are pretty interesting to me

This one is used by some X video drivers.
It is not specific to i386, it works on amd64 as well

Anyone here not cool with the idea that we outlaw all autists and send them to ADX? 108681928, you're cool with that, right? What about you, 108681936?

That's not a "yes".
