forcing a double fault is one of the methods used in kernel testing
:-) to ensure smooth recovery after a crash!
as is listed here...
look at helix comunity mailing list archive for those words...

Hello
Sorry, i am a bit late and slightly off topic. Floating points have
one slight issue wrt precision, for details check-out :

Sadly, there is no way to define the state of the floating point unit in the
kernel. Also, the presence of an FPU is not an assumption you want to make.
Lastly, it is a headache to keep a track of where you can use and FPU and
where you cannot (Yes, you can use a global lock, but why incur that
Related question - is there any place in the kernel where we really miss FPU
functionality ?
For eg. would we have better load average calculations if the kernel used
the FPU ?
Just a thought...
Best regards,

Do we miss it ? No ! We could always use a bunch of integers and a taylor
series instead ;-)

Hi,
Can anybody please tell me the reason as to why floating point
arithmetic is not very convinient in kernel code as against user code?

Its mostly for efficiency reasons.

Did you watch 'Matrix' movie?

Integer calculations are much more faster than floating

Generally, integer calculations are necessary and sufficient for the
things
done in kernel code. But if you really required floating point, you
can always
do

Latency is not accepted in kernel code:
