Hi All,
I googled for reason for using asmlinkage and found some people saying asmlinkage is there because of historical reason of using g++ to compile kernel in good old days.
Is it true?
Second, kernelnewbies wiki gives a good explanation of why is asmlinkage used.
My second query is why are taking arguments from stack a better idea than taking them from registers?
isn't register access supossed to be fast?
What am i missing here?
Any pointers?
TIA
pradeep
