Subject: [Intel-gfx] [PATCH 4/8] drm/i915/buddy: tweak CONTIGUOUS rounding
Date: Fri, 4 Mar 2022 17:23:29 +0000 [thread overview]
Message-ID: <20220304172333.991778-5-matthew.auld@intel.com> (raw)
In-Reply-To: <20220304172333.991778-1-matthew.auld@intel.com>
If this is an actual range allocation, and not some bias thing then the
resultant allocation will already be naturally contiguous without
needing any power-of-two rounding.
