Subject: [PATCH 23/25] drm/i915/selftests: Take a VM in kernel_context()
Date: Thu, 29 Apr 2021 14:03:38 -0500	[thread overview]
Message-ID: <20210429190340.1555632-24-jason@jlekstrand.net> (raw)
In-Reply-To: <20210429190340.1555632-1-jason@jlekstrand.net>

This better models where we want to go with contexts in general where
things like the VM and engine set are create parameters instead of being
set after the fact.
