Tiptop: Hardware Performance Counters

Interesting that this software has reached version 2.2 and it is not available in Debian yet. I filed a RFP: <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=754932" rel="nofollow">https:&#x2F;&#x2F;bugs.debian.org&#x2F;cgi-bin&#x2F;bugreport.cgi?bug=754932</a>

Is it possible to use these same hardware performance counters to perform a side-channel attack on another process?

Could someone please explain the differences and advantages of tiptop over using a program like htop for analysing performance for every day operations (if any)?

Slightly off-topic (maybe) but can this or another readily available tool be used to track counters during startup&#x2F;shutdown and provide a log of it which can then be imported in some viewer? (think something like windows Performance Monitor&#x2F;Event Tracer and the likes)

it mentions intel instrumentation instructions , does it work on other hardware though goes unmentioned in requirements? Say spark&#x2F;...
