Busy waiting is looping while checking whether a condition
changed. E.g.
while(condition_is_true());
It would be nicer to let the processor sleep for a while. I'm not sure
whether we can actually

Not yet. I will also need this for networking. Actually, we can do
still in this idle time. I will get back on this.
You can read the time in milliseconds, IIRC. You can use tha
For i/o delays on x86, Linux uses a sequence of outp(0x80). 0x80 is
usually unsed.
One to three times should be quite sufficient.

Hello,
Is there any mechanism to wait/sleep for a specified time in GRUB?
The reason I need something like this is that, for the ATA driver I am
working on, I need to be able to wait for a memory mapped register to
change, but I don't want to wait indefinitely.
