Subject: [PATCH 19/31] drm/i915: Add an i915_gem_vm_lookup helper
Date: Wed, 9 Jun 2021 12:44:06 -0500 [thread overview]
Message-ID: <20210609174418.249585-20-jason@jlekstrand.net> (raw)
In-Reply-To: <20210609174418.249585-1-jason@jlekstrand.net>
This is the VM equivalent of i915_gem_context_lookup. It's only used
once in this patch but future patches will need to duplicate this lookup
code so it's better to have it in a helper.
