[PATCH] drm/amdgpu: use correct rounding macro for 64-bit

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

 



From: Dave Airlie <airlied@xxxxxxxxxx>

This fixes 32-bit arm build due to lack of 64-bit divides.

Fixes: cb1c81467af3 ("drm/ttm: flip the switch for driver allocated resources v2")
