Bug ID: 459130
Summary: Monitoring crashes when there are offline CPU cores
Product: plasma-systemmonitor
Version: 5.25.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org

Target Milestone: ---
Created attachment 152067
--> https://bugs.kde.org/attachment.cgi?id=152067&action=edit
A modified page which shows the non functioning graphs (This is a 8-core system
with 4 cores disabled), also htop which successfully recognized these cores as
"offline".
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Open a superuser terminal.
2. Set a CPU core offline by entering: "echo 0 >
/sys/devices/system/cpu/cpu1/online" (This disables the second core of the CPU)
3. Open System Monitor
OBSERVED RESULT
All pages except "Processes" stops functioning, components showing blank charts
everywhere. Persists after application relaunch.
EXPECTED RESULT
Components that aren't CPU related keep functioning, while multicore CPU charts
should show "Offline" on these cores (or simply hide them from view)
