21 * Prototype: u64 cnt32_to_63(u32 cnt)
22 * Many hardware clock counters are only 32 bits wide and therefore have
23 * a relatively short period making wrap-arounds rather frequent. This
24 * is a problem when implementing sched_clock() for example, where a 64-bit
25 * non-wrapping monotonic value is expected to be returned.
26 *
27 * To overcome that limitation, let's extend a 32-bit counter to 63 bits
28 * in a completely lock free fashion. Bits 0 to 31 of the clock are provided
29 * by the hardware while bits 32 to 62 are stored in memory. The top bit in
30 * memory is used to synchronize with the hardware clock half-period. When
31 * the top bit of both counters (hardware and in memory) differ then the
32 * memory is updated with a new value, incrementing it when the hardware
33 * counter wraps around.
34 *
35 * Because a word store in memory is atomic then the incremented value will
36 * always be in synch with the top bit indicating to any potential concurrent
37 * reader if the value in memory is up to date or not with regards to the
38 * needed increment. And any race in updating the value in memory is harmless
39 * as the same value would simply be stored more than once.
40 *
41 * The only restriction for the algorithm to work properly is that this
42 * code must be executed at least once per each half period of the 32-bit
43 * counter to properly update the state bit in memory. This is usually not a
44 * problem in practice, but if it is then a kernel timer could be scheduled
45 * to manage for this code to be executed often enough.
46 *
47 * Note that the top bit (bit 63) in the returned value should be considered
48 * as garbage. It is not cleared here because callers are likely to use a
49 * multiplier on the returned value which can get rid of the top bit
50 * implicitly by making the multiplier even, therefore saving on a runtime
51 * clear-bit instruction. Otherwise caller must remember to clear the top
52 * bit explicitly.

1459 SMTC pseudo-interrupts between TCs are deferred and queued
1460 if the target TC is interrupt-inhibited (IXMT). In the first
1461 SMTC prototypes, these queued IPIs were serviced on return
1462 to user mode, or on entry into the kernel idle loop. The
1463 INSTANT_REPLAY option dispatches them as part of local_irq_restore()
1464 processing, which adds runtime overhead (hence the option to turn
1465 it off), but ensures that IPIs are handled promptly even under
1466 heavy I/O interrupt load.

19 * Variant clock event timer support for SMTC on MIPS 34K, 1004K
20 * or other MIPS MT cores.
21 *
22 * Notes on SMTC Support:
23 *
24 * SMTC has multiple microthread TCs pretending to be Linux CPUs.
25 * But there's only one Count/Compare pair per VPE, and Compare
26 * interrupts are taken opportunisitically by available TCs
27 * bound to the VPE with the Count register. The new timer
28 * framework provides for global broadcasts, but we really
29 * want VPE-level multicasts for best behavior. So instead
30 * of invoking the high-level clock-event broadcast code,
31 * this version of SMTC support uses the historical SMTC
32 * multicast mechanisms "under the hood", appearing to the
33 * generic clock layer as if the interrupts are per-CPU.
34 *
35 * The approach taken here is to maintain a set of NR_CPUS
36 * virtual timers, and track which "CPU" needs to be alerted
37 * at each event.
38 *
39 * It's unlikely that we'll see a MIPS MT core with more than
40 * 2 VPEs, but we *know* that we won't need to handle more
41 * VPEs than we have "CPUs". So NCPUs arrays of NCPUs elements
42 * is always going to be overkill, but always going to be enough.

53 * roughly once every four billion events, which at 1000 HZ means
54 * about once every 50 days. If that's actually a problem, one

237 * - the PIT is running at roughly 1.19MHz

239 * - each IO is going to take about 1us on real hardware,

242 * update - anything else implies a unacceptably slow CPU
243 * or PIT for the fast calibration to work.
244 *
245 * - with 256 PIT ticks to read the value, we have 214us to
246 * see the same MSB (and overhead like doing a single TSC
247 * read per MSB value etc).
248 *
249 * - We're doing 2 reads per loop (LSB, MSB), and we expect

251 * So we expect a count value of around 100. But we'll be
252 * generous, and accept anything over 50.

254 * - if the PIT is stuck, and we see *many* more reads, we
255 * return early (and the next caller of pit_expect_msb()
