Hello asm gurus..
I need a simple (??) change to atomic_inc() functionality. so that i can
increment and return the
value of the variable.
current implementation in linux/include/asm/atomic.h does not do this job.
any help would be greatly appreciated.
ashokr
from atomic.h
also if there is any reference to the gnu asm symtax, please send me a
pointer..
i can understand what the LOCK "incl %0 means.. but not sure what the rest
is for.
thanks
ashokr
static __inline__ void atomic_inc(atomic_t *v)
{
__asm__ __volatile__(
LOCK "incl %0"
:"=m" (v->counter)
:"m" (v->counter));
}
