Subject: tools/misc/xenpm: fix getting info when some CPUs are offline
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ffb60a58df48419c1f2607cd3cc919fa2bfc9c2d;p=people%2Fsstabellini%2Fxen-unstable.git%2F.git

tools/misc/xenpm: fix getting info when some CPUs are offline

Use physinfo.max_cpu_id instead of physinfo.nr_cpus to get max CPU id.
This fixes for example 'xenpm get-cpufreq-para' with smt=off, which
otherwise would miss half of the cores.
