Subject: [PATCH 1/8] drm/i915: Allow use of get_dma_address for stolen backed objects
Date: Tue, 15 Dec 2015 16:26:01 +0530 [thread overview]
Message-ID: <1450176968-22110-2-git-send-email-ankitprasad.r.sharma@intel.com> (raw)
In-Reply-To: <1450176968-22110-1-git-send-email-ankitprasad.r.sharma@intel.com>
From: Ankitprasad Sharma <ankitprasad.r.sharma@intel.com>
i915_gem_object_get_dma_address function is used to retrieve the dma address
of a particular page so as to map it in a given GTT entry for CPU access.
This function would be used for stolen backed objects also for tasks like
pwrite, clearing of the pages etc. So the obj->get_page.sg needs to be
initialized for the stolen objects also.
