Re: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

It seems this bug is triggered by changeset #20430, although it doesn''t
seem to change hpet.c, so the actual problem will probably be elsewhere.
#20429 is booting and working fine for me (at least it doesn''t give
this bug).
changesets #20430 up until tip not, i can trigger this bug every time by
compiling xen (make xen), this makes it panic and reboot.

RE: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

Maybe I missed some referecen to cpu_possible_map, since now the
cpu_possible_map is all 1s.

I have no access to my development machine in hand, will check the usage when I
back to office tomorrow.

RE: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

Have a quick look on the code,

This should be caused by following code in hpet_broadcast_init(). Without
changeset 20430, the num_possible_cpus() get 4 on your platform, and is 64 after
the change.
I suspect this is a bug just revealed by #20430, I will have a deep look on the
hpet logic and discuss with WeiGang to fix it.

        if ( num_hpets_used < num_possible_cpus() )
        {
            hpet_attach_channel = hpet_attach_channel_share;
            hpet_detach_channel = hpet_detach_channel_share;
        }

Thanks

Re: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

Hello Yunhong,

I was allready afraid it was only revealed by that changeset, 60 cpu''s
for free seems to good to be true :(
Hope you can find it soon, it crashes the hypervisor frequently and fast (often
right after boot).
At least I didn''t buy my null-modem cable and setup a serial console
for nothing :-)

Thx,

RE: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

Hi, Sander, can you please have a try to following patch?

The reason for this issue is,  in hpet_broadcast_enter(), it will return
directly if timer_deadline==0 without setting the channel, while 
hpet_broadcast_exit() missed the checking.

As the timer_deadline is only changed in softirq context as per_cpu action, it
will not be changed between hpet_broadcast_entry()/hpet_broadcast_exit(), the
checking is safe.

We considered to use the num_present_cpu() instead of num_possible_cpu() in
hpet_broadcast_init(), but that seems not so important, since it is already
limited by HPET''s channel number already.

Re: [Xen-devel] [xen-3.5][linux-pvops-2.6.31.6] Xen BUG at hpet.c:663 triggered by changeset #20430

Hello Yunhong,

Your patch fixes it !

Thanks,

Sander

directly if timer_deadline==0 without setting the channel, while 
hpet_broadcast_exit() missed the checking.
> As the timer_deadline is only changed in softirq context as per_cpu action,
it will not be changed between hpet_broadcast_entry()/hpet_broadcast_exit(), the
checking is safe.
> We considered to use the num_present_cpu() instead of num_possible_cpu() in
hpet_broadcast_init(), but that seems not so important, since it is already
limited by HPET''s channel number already.
