[PATCH i-g-t 0/3] gputop memory usage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

Same general approach as with engine utilisation, adding parsing of the relevant
fdinfo fields and plumbing to client discovery helpers to finally present some
of the available data in gputop:

DRM minor 0
 PID      MEM      RSS  render    copy     video   NAME
8098     124M     124M |███████||       ||       ||       | neverball
 888      76M      75M |▊      ||       ||       ||       | Xorg
 966      12M      12M |       ||       ||       ||       | xfwm4

Or with Wayland:

DRM minor 0
 PID      MEM      RSS    render        copy         video    video-enhance NAME
2093     191M     191M |▊          ||           ||           ||           | gnome-shell
DRM minor 128
 PID      MEM      RSS    render        copy         video    video-enhance NAME
2551      71M      71M |██▉        ||           ||           ||           | neverball
2553      50M      50M |           ||           ||           ||           | Xwayland

There is probably scope to consolidate some of the igt_drm_fdinfo code and to
improve on the presentation but this is a start.

For now, out of the available memory categories, only total and resident are
displayed, and also all discovered memory regions are summed up and shown under
a single heading.

v2:
 * One style tweak, two missing s-o-b, one build failure.
