Subject: [PATCH 10/11] drm/i915: Reject bind_to_gtt() early if object > aperture
Date: Thu, 27 May 2010 13:18:21 +0100
Message-ID: <1274962702-6530-11-git-send-email-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <1274962702-6530-1-git-send-email-chris@chris-wilson.co.uk>

If the object is bigger than the entire aperture, reject it early
before evicting everything in a vain attempt to find space.

v2: Use E2BIG as suggested by Owain G. Ainsworth.
