[PATCH 08/32] drm/i915: Simplify reset_counter handling during atomic modesetting

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

 



Now that the reset_counter is stored on the request, we can rearrange
the code to handle reading the counter versus waiting during the atomic
modesetting for readibility (by deleting the hairiest of codes).
