Bug description:
[ Impact ]
When resizing the terminal window, intel_gpu_top may crash if the window
becomes small enough. The output when it crashes is:
intel_gpu_top: ../tools/intel_gpu_top.c:1202: print_percentage_bar: Assertion
`max_len > 0' failed.
The fix has been reported and fixed upstream recently :
https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/issues/143
The fix has been part of a serie of fixes that improve intel_gpu_top
UI behavior for some corner cases :
https://patchwork.freedesktop.org/series/124890/
The proposed fix consists of backporting these fixes to affected
Ubuntu releases (Jammy, Mantic and Noble)
Tvrtko Ursulin (4):
tools/intel_gpu_top: Fix clients header width when no clients
tools/intel_gpu_top: Fix client layout on first sample period
tools/intel_gpu_top: Optimise interactive display a bit
tools/intel_gpu_top: Handle narrow terminals more gracefully
[ Test Plan ]
Run intel_gpu_top inside a console
Resize the console with the mouse to it smallest size
[ Where problems could occur ]
The problem occurs when intel_gpu_top try to draw information on the
console
[ Other Info ]
This fix should not cause regression on any other feature.
