While troubleshooting some lags (https://together.jolla.com/question/176421/severe-lags-after-updating-to-2137/) I thought that the easiest way to get the cause of the lags is to use perf. My phone model is Jolla 1.

Is there an easy way of installing perf on Sailfish OS?

I tried to use pkcon.

$ pkcon search name perf Available kernel-adaptation-sbj-perf-3.4.108.20161101.1-10.42.3.jolla.armv7hl Linux profiling with performance counters

But trying installing it shows an error:

$ pkcon install kernel-adaptation-sbj-perf Installing

Fatal error: kernel-adaptation-sbj-perf-3.4.108.20161101.1-10.42.3.jolla.armv7hl requires libdw.so.1, but this requirement cannot be provided
