Can someone please point me to the context switching code. I am
interested in the context switch structure and the values that are
saved. I am chasing a weird problem with some numerical code that uses
mmx instructions to get flush to zero to work. Specifically I am calling
macro which in turn ends up calling _mm_setcsr(), wherever that might be
What I am trying to figure out is a.) is this register value properly
set/reset during context switch and b.) is this particular register
properly transfered when the process gets moved to another CPU.
I assume that this is a configurable option in the kernel since PII and
Pentium do not have this instruction, and thus it could just be that my
kernel is not configured correctly.
I tried to find this type of info without posting but failed.
