Looking at the kernel sources, I see that in /usr/src/sys/i386/i386/trap.c,
--- snip
/*
* note: PCPU_LAZY_INC() can only be used if we can afford
* occassional inaccuracy in the count.
*/
PCPU_LAZY_INC(cnt.v_syscall);
--- snip
This seems to be a macro to update a per-CPU variable. But, AFAIK, there is
*only* one variable now. Is it correct?
The ia64 version (/usr/src/sys/ia64/ia64) happily updates this variable:
---- snip
syscall(int code, u_int64_t *args, struct trapframe *framep)
{
struct sysent *callp;
struct thread *td;
struct proc *p;
int error = 0;
u_int64_t oldip, oldri;
u_int sticks;
cnt.v_syscall++;
---- snip
What happens here? Is this a bug caught in the middle of a change?
BTW... Is there a major change in the sysctl MIB for 5.0-RELEASE? I am using
it to get most of the information logged to Orca and I should take it into
account.
Thanks,
Borja.
