Hi, list
Here is the code snippet:
#define ipipe_read_tsc(t) \
__asm__ __volatile__("rdtsc" : "=A"(t))I found that the rdtsc (Read Time-Stamp Counter) instruction is used to determine how many CPU ticks took place since the processor was reset. But what does "=A"(t) mean? Thank you for your attention to this matter. _______________________________________________ Kernelnewbies mailing list [email protected] https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
