[Mesa-dev] [RFC 0/6] gallium/hud: write displayed graph values into files

[Edmondo Tommasina]

Introduce a new envvar (GALLIUM_HUD_DUMP_DIR) to write the displayed
hud values into files.

For example:
GALLIUM_HUD_DUMP_DIR="/tmp/" GALLIUM_HUD="fps,cpu+GPU-load" glxgears

In the /tmp directory it will create 3 files (fps, cpu and GPU-load)
with all the values inside.
