Subject: tools/power turbostat: fix dump for AMD cpus
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6799ba84cab7784cb9f060a24790482de209e318;p=linux.git

tools/power turbostat: fix dump for AMD cpus

turbostat --Dump exits early with status 243 (-13)

get_counters() calls get_msr_sum() on zen CPUS
for MSR_PKG_ENERGY_STAT, but per_cpu_msr_sum
has not been initialized.
