Subject: [PATCH 17/25] drm/i915/gem: Use the proto-context to handle create parameters
Date: Thu, 29 Apr 2021 14:03:32 -0500	[thread overview]
Message-ID: <20210429190340.1555632-18-jason@jlekstrand.net> (raw)
In-Reply-To: <20210429190340.1555632-1-jason@jlekstrand.net>

This means that the proto-context needs to grow support for engine
configuration information as well as setparam logic.  Fortunately, we'll
be deleting a lot of setparam logic on the primary context shortly so it
will hopefully balance out.
