Hi Stéphane.
MIPS do have a way to access count register from user space.
Unfortunately there is no GCC intrinsic function for it, you may try following
inline assembly.
static inline unsigned long get_count() {
unsigned long count;
asm volatile ("rdhwr %[rt], $2" : [rt] "=d" (count));
return count;
}
return Val_long (get_count());
Thanks.
