Subject: [RFC 15/16] drm/nouveau: support GK20A in nouveau_accel_init()
Date: Sat, 1 Feb 2014 12:16:57 +0900 [thread overview]
Message-ID: <1391224618-3794-16-git-send-email-acourbot@nvidia.com> (raw)
In-Reply-To: <1391224618-3794-1-git-send-email-acourbot@nvidia.com>
GK20A does not embed a dedicated COPY engine and thus cannot allocate
the copy channel that nouveau_accel_init() attempts to create. It also
lacks any display hardware, so the creation of a software channel does
not apply neither.
