guys, I saw on web that sysenter/sysexit are so faster then others way

now is my stupid questio

how do I use those instructions on my kernel ?

I got a simples system call functions...

like to get mouse state. read file from floppy. I got a ring3 protection too

could anyone help me please ?

just to understand. do I have to use ints together?

I suggest you read the intel manuals on how those instructions work and how you can use them.

You'll still need int xx as a syscall for when sysenter isn't supported
