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)); }
