Subject: perf tools: Put proper period for for samples without PERIOD sample_type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc5290869d0a7f7abbde76ac95a7f7b6f5d7bb7b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

perf tools: Put proper period for for samples without PERIOD sample_type

We use PERF_SAMPLE_PERIOD sample type only for frequency
setup -F (default) option. The -c does not need store period,
because it's always the same.

In -c case the report code uses '1' as  period. Fixing
it to perf_event_attr::sample_period.
