[Xen-ia64-devel] [PATCH] fixes DOM0_PHYSINFO hypercall

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

This patch fixes DOM0_PHYSINFO hypercall.

However, I found a problem in 'smp_num_siblings'.
I changed the setting of BIOS to disabled the hyperthread, so I expected 
'smp_num_siblings' to 1.
But, its value is 2, because the value of log_overview.tpc 
(PAL_LOGICAL_TO_PHYSICAL) is 2.
Is there any way to know the current setting of the hyperthread?

Best Regards,
 Kan
