Date: Thu, 09 Nov 2000 12:27:29 +1300	[thread overview]
Message-ID: <3A09E161.ACB11253@ihug.co.nz> (raw)

hi i need fast fpu in the kernel for my lexos work
so how am i going to do it on the i386

1 . can i add some save / restore code to the task swicher ( the right
way )
     so when it switchs from user to kernel task its saves the fpu state
?

2 . put the save / restore code in my code (NOT! GOOD! i do not wont to
do it this way it is not the right way)

so i have to use fpu in the kernel so its just how am i going to do it ?

thank you

    David Rundle <sector2@ihug.co.nz>
