commit c1c95c4d38ae2abc82c7d2277102e614fd76dbf5 Author: Marek Marczykowski-Górecki <marmarek@xxxxxxxxxxxxxxxxxxxxxx> AuthorDate: Wed Oct 31 14:04:58 2018 +0100 Commit: Ian Jackson <ian.jackson@xxxxxxxxxxxxx> CommitDate: Thu May 16 16:53:29 2019 +0100 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.
