Just upgraded a box at home to new hardware with embedded Intel
graphics (i5 Haswell), did a clean install of Fedora 21, and while
poking around trying to fix a few issues while rebuilding my config
spotted something I've not noticed before. With KDE running "lsof"
lists over a thousand entries like this:
Xorg.bin 659 662 root DEL REG 0,4
16016 /drm mm object
Xorg.bin 659 662 root DEL REG 0,4
16011 /drm mm object
kwin 964 zocalo DEL REG 0,4
38725 /drm mm object
kwin 964 zocalo DEL REG 0,4
19275 /drm mm object
QProcessM 964 986 zocalo DEL REG 0,4
19277 /drm mm object
QProcessM 964 986 zocalo DEL REG 0,4
47240 /drm mm object
These are the only three processes that appear to own these files, and
the number of entries appears to fluctuate as windows are
opened/closed, and other GUI events happen.
A Google search comes up with a bunch of stuff about memory leaks from
a few years ago, plus some documention on Kernel memory management,
but I couldn't find anything that explains what these "/drm mm object"
entries are, whether this is normal behaviour, or if there is
potentially a problem.
Any ideas?
