Using ingo\u0027s time-warp-test.c,\nI could trigger a scenario as bad as 1.5mi warps a minute in some systems.\n(to be fair, it wasn\u0027t that bad in most of them). Investigating further, I\nfound out that such warps were caused by the very offset-based calculation\npvclock is based on.\n\nThis happens even on some machines that report constant_tsc in its tsc flags,\nspecially on multi-socket ones.\n\nTwo reads of the same kernel timestamp at approx the same time, will likely\nhave tsc timestamped in different occasions too. This means the delta we\ncalculate is unpredictable at best, and can probably be smaller in a cpu\nthat is legitimately reading clock in a forward ocasion.\n\nSome adjustments on the host could make this window less likely to happen,\nbut still, it pretty much poses as an intrinsic problem of the mechanism.\n\nA while ago, I though about using a shared variable anyway, to hold clock\nlast state, but gave up due to the high contention locking was likely\nto introduce, possibly rendering the thing useless on big machines. I argue,\nhowever, that locking is not necessary.\n\nWe do a read-and-return sequence in pvclock, and between read and return,\nthe global value can have changed. However, it can only have changed\nby means of an addition of a positive value. So if we detected that our\nclock timestamp is less than the current global, we know that we need to\nreturn a higher one, even though it is not exactly the one we compared to.\n\nOTOH, if we detect we\u0027re greater than the current time source, we atomically\nreplace the value with our new readings. This do causes contention on big\nboxes (but big here means *BIG*), but it seems like a good trade off, since\nit provide us with a time source guaranteed to be stable wrt time warps.\n\nAfter this patch is applied, I don\u0027t see a single warp in time during 5 days\nof execution, in any of the machines I saw them before.\n\nSigned-off-by: Glauber Costa \u003cglommer@redhat.com\u003e\nAcked-by: Zachary Amsden \u003czamsden@redhat.com\u003e\nCC: Jeremy Fitzhardinge \u003cjeremy@goop.org\u003e\nCC: Avi Kivity \u003cavi@redhat.com\u003e\nCC: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\nCC: Zachary Amsden \u003czamsden@redhat.com\u003e\nSigned-off-by: Marcelo Tosatti \u003cmtosatti@redhat.com\u003e\n" }, { "commit": "424c32f1aa3112632a657d45698c8e7666668f78", "tree": "c63fd6d83b6f2cbcb979b3f55c9a07425b13053f", "parents": [ "b69e8caef5b190af48c525f6d715e7b7728a77f6" ], "author": { "name": "Glauber Costa", "email": "glommer@redhat.com", "time": "Tue May 11 12:17:39 2010 -0400" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Wed May 19 11:40:59 2010 +0300" }, "message": "x86, paravirt: Enable pvclock flags in vcpu_time_info structure\n\nThis patch removes one padding byte and transform it into a flags\nfield.
