[Mesa-dev] [PATCH] nvc0: fix wrong max value for driver queries

[Samuel Pitoiset]

The maximum value of a Gallium HUD's panel is automatically adjusted
when the current value is greater than the max. If we set the
pipe_query_driver_info::max_value to UINT64_MAX, the maximum value is
never adjusted and this results in a right instead of a pretty curve
which is correctly scaled.
