[Intel-gfx] [RFC 0/1] drm/i915: Add scheduling priority to per-context parameters

[Dave Gordon]

A proposal for an ioctl to allow a user process to alter its GPU
scheduling priority. It's defined as a new per-context parameter,
and each execbuffer submitted thereafter inherits its priority
from the context. This allows a single process to associate
different priorities with different contexts, perhaps being used
for different purposes (e.g. updating the GUI vs. scanning SETI
data for alien transmissions).
