This test system was configured to use a TSC clocksource, disabled C states, and lowered the timer slop. I am not claiming the timer slop change was solely responsible for the best results. In other testing with the default timer slop setting of 10 (100 microseconds), the average PDL would run slightly higher, but the spikes were much higher and more in number, often near the 1000s and happening multiple times per 10 minutes of testing. - Ryan ___ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

I think we can easily share the experimental data (cyclictest output and plots). Moreover, we can share the scripts and tools for running the experiments (so, everyone can easily reproduce the numbers by simply typing "make" and waiting for some time :) I'll try to package the results and the scripts/tools this evening, and I'll send them.

We need to check whether all the other places where smt_idle is used would be ok with that (I think they are, as we pretty much always end up &&-ing it with online or active anyway), or if they need some reshuffling (and if yes, how that looks like). I can check this on Monday.

How does that help? Only if all siblings are marked as idle in rqd->idle we set any bits in rqd->smt_idle (all siblings). Or did you mean rqd->idle instead? This might be problematic in case of runqueue per cpu, though. Another idea: we could introduce a credit2 pcpu data cpumask pointer for replacement of the cpu_sibling_mask. For runqueue per cpu it would pount to cpumask_of(cpu), for the "normal case" it would point to the correct cpu_sibling_mask, and for special cases we could allocate a mask if needed.

Thanks for the detailed explanation. IMO it would be better to let
OVMF do the BAR placement instead of having to do it in hvmloader,
this just causes code duplication between projects and there's nothing
Xen-specific about the PCI resource allocation.
I will try to find some time to look into this, albeit I'm not going
to be able to work in this immediately. I'm more than happy if someone
else has spare time and wants to pick this up.
Roger.

I'm currently away from home, and cannot really help much ATM, also I
don't have access to a system with a CPU that exhibits such behavior,
much makes debugging it harder.
I've taken a look at the difference in AP startup code between Linux
and Xen at or before the point you get the hang, and I'm not able to
spot anything obvious that could make Linux work and not Xen.
I've realized however that Linux disables interrupts when writing to
the local APIC ICR register for other reasons, but maybe this somehow
affects bring up in this CPU, hence the patch below. Could you please
give it a spin together with the patch provided by Andrew?
There are other minor differences between Linux and Xen AP bring up,
so I guess there are further changes to test if the patch below
doesn't make things better.
Thanks, Roger.
