I am trying to implement very simple lightweight processes for an application I am writing. I am having trouble finding the information I need to do context switching on a sun4. I assume I need to use the trap ST_FLUSH_WINDOWS (or maybe ST_CLEAN_WINDOWS?), but all I have is the sun4 assembly language reference, which doesn't explain what anything does! If somebody could explain what that trap, and the instructions call, jmpl, save and restore do exactly, I would be very grateful.
