Hi, my problem is rr doesn't support cpu 0x906e0. Details are listed below:
$  matlab_R2018a_glnxa64 rr matlab


rr: Warning: Your CPU frequency governor is 'powersave'.  rr strongly
    recommends that you use the 'performance' governor.  Not using the
    'performance' governor can cause rr to be at least 2x slower
    on laptops.


    On Fedora-based systems, you can enable the 'performance' governor
    by running the following commands:


    $ sudo dnf install kernel-tools
    $ sudo cpupower frequency-set -g performance


[FATAL /build/rr-jR8ti5/rr-4.1.0/src/RecordSession.cc:1344:create() errno: 0 'Success'] 
 -> rr needs /proc/sys/kernel/perf_event_paranoid <= 1, but it is 3.
Change it to 1, or use 'rr record -n' (slow).

How can I make rr run on my computer? Thanks.
