Roderick Klein reminds:
Anyway in 486 or possibly even the 386 computer the HLT instruction was
introduced. This is a kind of quick on off switches that makes the CPU idle.
It reduces energy consumption and also the heat developement! Especialy
in laptops this is important. Your hard ware lasts longer and your battery
life increases!
Orginaly the _W4 kernel (which does not support multiple CPU's) had
support for CPU HLT instruction.
The SMP kernel we now use today in eCS (also on machines with a single
core system) does not have HLT support build in.
People tried in various ways to implement this. Andy Willes tried a
patch but from what I read that did not work in all cases.
Implementing such a patch is also no easy. It now seems David come up
with a such method.
As every CPU (amd and Intel) support his HLT instruction it should make
people there computers a lot cooler and reduce the electricityt bill :-)
