|

| 19 | *
|
|---|
| 20 | * The Time Manager abstracts the CPU clocks and manages timers used by the VMM,
|
|---|
| 21 | * device and drivers.

| 26 | * @section sec_tm_clocks Clocks
|
|---|
| 27 | *
|
|---|
| 28 | * There are currently 4 clocks:
|
|---|
| 29 | * - Virtual (guest).
|
|---|
| 30 | * - Synchronous virtual (guest).
|
|---|
| 31 | * - CPU Tick (TSC) (guest). Only current use is rdtsc emulation. Usually a
|
|---|
| 32 | * function of the virtual clock.
|
|---|
| 33 | * - Real (host). This is only used for display updates atm.
|
|---|
| 34 | *
|
|---|
| 35 | * The most important clocks are the three first ones and of these the second is
|
|---|
| 36 | * the most interesting.
|
|---|
| 37 | *
|
|---|
| 38 | *
|
|---|
| 39 | * The synchronous virtual clock is tied to the virtual clock except that it
|
|---|
| 40 | * will take into account timer delivery lag caused by host scheduling. It will
|
|---|
| 41 | * normally never advance beyond the head timer, and when lagging too far behind
|
|---|
| 42 | * it will gradually speed up to catch up with the virtual clock. All devices
|
|---|
| 43 | * implementing time sources accessible to and used by the guest is using this
|
|---|
| 44 | * clock (for timers and other things). This ensures consistency between the
|
|---|
| 45 | * time sources.
|
|---|
| 46 | *
|
|---|
| 47 | * The virtual clock is implemented as an offset to a monotonic, high
|
|---|
| 48 | * resolution, wall clock. The current time source is using the RTTimeNanoTS()
|
|---|
| 49 | * machinery based upon the Global Info Pages (GIP), that is, we're using TSC
|
|---|
| 50 | * deltas (usually 10 ms) to fill the gaps between GIP updates. The result is
|
|---|
| 51 | * a fairly high res clock that works in all contexts and on all hosts. The
|
|---|
| 52 | * virtual clock is paused when the VM isn't in the running state.
|
|---|
| 53 | *
|
|---|
| 54 | * The CPU tick (TSC) is normally virtualized as a function of the synchronous
|
|---|
| 55 | * virtual clock, where the frequency defaults to the host cpu frequency (as we
|
|---|
| 56 | * measure it). In this mode it is possible to configure the frequency. Another
|
|---|
| 57 | * (non-default) option is to use the raw unmodified host TSC values. And yet
|
|---|
| 58 | * another, to tie it to time spent executing guest code. All these things are
|
|---|
| 59 | * configurable should non-default behavior be desirable.
|
|---|
| 60 | *
|
|---|
| 61 | * The real clock is a monotonic clock (when available) with relatively low
|
|---|
| 62 | * resolution, though this a bit host specific. Note that we're currently not
|
|---|
| 63 | * servicing timers using the real clock when the VM is not running, this is
|
|---|
| 64 | * simply because it has not been needed yet therefore not implemented.
|
|---|
| 65 | *
|
|---|
| 66 | *
|
|---|
| 67 | * @subsection subsec_tm_timesync Guest Time Sync / UTC time
|
|---|
| 68 | *
|
|---|
| 69 | * Guest time syncing is primarily taken care of by the VMM device. The
|
|---|
| 70 | * principle is very simple, the guest additions periodically asks the VMM
|
|---|
| 71 | * device what the current UTC time is and makes adjustments accordingly.
|
|---|
| 72 | *
|
|---|
| 73 | * A complicating factor is that the synchronous virtual clock might be doing
|
|---|
| 74 | * catchups and the guest perception is currently a little bit behind the world
|
|---|
| 75 | * but it will (hopefully) be catching up soon as we're feeding timer interrupts
|
|---|
| 76 | * at a slightly higher rate. Adjusting the guest clock to the current wall
|
|---|
| 77 | * time in the real world would be a bad idea then because the guest will be
|
|---|
| 78 | * advancing too fast and run ahead of world time (if the catchup works out).
|
|---|
| 79 | * To solve this problem TM provides the VMM device with an UTC time source that
|
|---|
| 80 | * gets adjusted with the current lag, so that when the guest eventually catches
|
|---|
| 81 | * up the lag it will be showing correct real world time.
|
|---|
| 82 | *
|
|---|
| 83 | *
|
|---|
| 84 | * @section sec_tm_timers Timers
|
|---|
| 85 | *
|
|---|
| 86 | * The timers can use any of the TM clocks described in the previous section.
|
|---|
| 87 | * Each clock has its own scheduling facility, or timer queue if you like.
|
|---|
| 88 | * There are a few factors which makes it a bit complex. First, there is the
|
|---|
| 89 | * usual R0 vs R3 vs. RC thing. Then there are multiple threads, and then there
|
|---|
| 90 | * is the timer thread that periodically checks whether any timers has expired
|
|---|
| 91 | * without EMT noticing. On the API level, all but the create and save APIs
|
|---|
| 92 | * must be multithreaded. EMT will always run the timers.
|
|---|
| 93 | *
|
|---|
| 94 | * The design is using a doubly linked list of active timers which is ordered
|
|---|
| 95 | * by expire date. This list is only modified by the EMT thread. Updates to
|
|---|
| 96 | * the list are batched in a singly linked list, which is then processed by the
|
|---|
| 97 | * EMT thread at the first opportunity (immediately, next time EMT modifies a
|
|---|
| 98 | * timer on that clock, or next timer timeout). Both lists are offset based and
|
|---|
| 99 | * all the elements are therefore allocated from the hyper heap.
|
|---|
| 100 | *
|
|---|
| 101 | * For figuring out when there is need to schedule and run timers TM will:
|
|---|
| 102 | * - Poll whenever somebody queries the virtual clock.
|
|---|
| 103 | * - Poll the virtual clocks from the EM and REM loops.
|
|---|
| 104 | * - Poll the virtual clocks from trap exit path.
|
|---|
| 105 | * - Poll the virtual clocks and calculate first timeout from the halt loop.
|
|---|
| 106 | * - Employ a thread which periodically (100Hz) polls all the timer queues.
