This + * is a problem when implementing sched_clock() for example, where a 64-bit + * non-wrapping monotonic value is expected to be returned. + * + * To overcome that limitation, let's extend a 32-bit counter to 63 bits + * in a completely lock free fashion. Bits 0 to 31 of the clock are provided + * by the hardware while bits 32 to 62 are stored in memory. The top bit in + * memory is used to synchronize with the hardware clock half-period. When + * the top bit of both counters (hardware and in memory) differ then the + * memory is updated with a new value, incrementing it when the hardware + * counter wraps around. + * + * Because a word store in memory is atomic then the incremented value will + * always be in synch with the top bit indicating to any potential concurrent + * reader if the value in memory is up to date or not with regards to the + * needed increment. And any race in updating the value in memory is harmless + * as the same value would simply be stored more than once. + * + * The only restriction for the algorithm to work properly is that this + * code must be executed at least once per each half period of the 32-bit + * counter to properly update the state bit in memory. This is usually not a + * problem in practice, but if it is then a kernel timer could be scheduled + * to manage for this code to be executed often enough. + * + * Note that the top bit (bit 63) in the returned value should be considered + * as garbage. It is not cleared here because callers are likely to use a + * multiplier on the returned value which can get rid of the top bit + * implicitly by making the multiplier even, therefore saving on a runtime + * clear-bit instruction. Otherwise caller must remember to clear the top + * bit explicitly. + */ +#define cnt32_to_63(cnt_lo) \ +({ \ + static volatile u32 __m_cnt_hi; \ + union cnt32_to_63 __x; \ + __x.hi = __m_cnt_hi; \ + __x.lo = (cnt_lo);
