kernel/sched_clock.c has the comment:
* The clock: sched_clock_cpu() is monotonic per cpu, and should be somewhat
* consistent between cpus (never more than 2 jiffies difference).
The two jiffy restriction is way too restrictive.
Historically sched_clock() is intended to measure the amount of
schedulable time occurring on a CPU. On a virtual cpu, that is affected
by the amount of physical cpu time the hypervisor schedules for a vcpu,
and can therefore advance in a very non-continuous way, depending on the
overall load on the host system. It is, however, the only timebase that
gives the kernel a reasonable hope of determining how much cpu a process
actually got scheduled.
The net result is that the sched_clock timebase is 1) monotonic, 2)
loses arbitrary amounts of time against a system monotonic clock, 3)
per-cpu, with 4) arbitrary drift between different cpu's sched_clocks.
Tying the sched_clocks of different cpus together in any way loses these
properties, and just turns it into another system wide monotonic clock,
which seems redundant given that we already have one (I understand that
the relatively loose synchronization allows it to be implemented more
efficiently than a normal monotonic clock).
At the moment the x86 sched_clock is hooked through paravirt_ops so that
the underlying hypervisor can provide precise scheduled time
information, with the hope that the scheduler will use it to make better
decisions. However if the scheduler needs to be lied to then I can do
that too, but it's a pity to throw away information that's available to it.

I won't argue whether this is a good thing or a bad thing, but I did
find a problem in the current implementation.

Currently, I've found that it is quite easy to observe scd->clock, and
therefore rq->clock, running backwards, losing the monotonic quality.
This patch demonstrates the problem. I've found it triggers often on my
laptop (Lenovo T60p) just doing everyday work. I'll follow up with a
patch that fixes the problem. I'll let Peter and Ingo judge if it is
the correct fix.

sched_clock: prevent scd->clock from moving backwards
When sched_clock_cpu() couples the clocks between two cpus, it may
increment scd->clock beyond the GTOD tick window that __update_sched_clock()
uses to clamp the clock. A later call to __update_sched_clock() may move
the clock back to scd->tick_gtod + TICK_NSEC, violating the clock's
monotonic property.
This patch ensures that scd->clock will not be set backward.

Ah, yes indeed, this comes from the tick not happening at the same time
on different cpus, so if we use a local timestamp to move a remote clock
forward, this scenario could indeed happen.
The fix looks good to me, good catch, thanks shaggy!
A related 'fix' which I'm still not quite sure about is making the
window 'tick_gtod + 2*TICK_NSEC'. That increases the max observed
difference to 4 jiffies, but allows ticks to be 'late' a bit without
first holding back time and then jumping ahead again.

hm, -tip testing found a sporadic hard lockup during bootup, and i've
bisected it back to this patch. They happened on 64-bit test-systems.
I've attached the .config that produced the problem.
i reverted the patch and the lockups went away. But i cannot see what's
wrong with it ...
The lockups were at random places during bootup, such as:
[ 0.000000] initcall init_mbcache+0x0/0x20 returned 0 after 0 msecs
[ 0.000000] calling dquot_init+0x0/0x100 @ 1
[ 0.000000] VFS: Disk quotas dquot_6.5.1
[ 0.000000] Dquot-cache hash table entries: 512 (order 0, 4096 bytes)
[ 0.000000] initcall dquot_init+0x0/0x100 returned 0 after 10 msecs
[ 0.000000] calling init_v2_quota_format+0x0/0x20 @ 1
[ 0.000000] initcall init_v2_quota_format+0x0/0x20 returned 0 after 0 msecs
[ 0.000000] calling dnotify_init+0x0/0x30 @ 1
[... hard lockup ...]
weird ...

We want wrap_max(scd->clock, scd->tick_gtod + TICK_NSEC), not
wrap_min(). The problem I am trying to fix is that scd->tick_gtod +
TICK_NSEC may be too low. The upper bound needs to be at LEAST
scd->clock. Limiting it to scd->clock all the time is disastrous. :-)
I'll fix the patch and retest it before sending it again.
Sorry about my sloppiness.

I'm definitely running with the new patch now. Here goes:
-------------------------------------------------
sched_clock: prevent scd->clock from moving backwards
When sched_clock_cpu() couples the clocks between two cpus, it may
increment scd->clock beyond the GTOD tick window that __update_sched_clock()
uses to clamp the clock. A later call to __update_sched_clock() may move
the clock back to scd->tick_gtod + TICK_NSEC, violating the clock's
monotonic property.
This patch ensures that scd->clock will not be set backward.

ah, so the lockup bug was probably that sched_clock() was never going
forwards properly so some task was scheduled forever and livelocked the
system?

no problem - and it's good that our bad-patch filters worked properly
and efficiently :-)
