Subject: [PATCH] drm/i915/gem: Execbuffer objects must have struct pages.
Date: Mon, 11 Mar 2024 13:37:42 -0700 [thread overview]
Message-ID: <20240311203742.3004155-1-jonathan.cavitt@intel.com> (raw)
We cannot write requests to objects without struct pages, so escape
early if the requests are bound to objects that lack them.
Signed-off-by: Jonathan Cavitt <jonathan.cavitt@intel.com>
