Subject: [Intel-gfx] [PATCH v2 3/6] drm/i915/adlp: Assert that VMAs in DPT start at 0
Date: Mon,  6 Sep 2021 21:27:12 +0300	[thread overview]
Message-ID: <20210906182715.3915100-4-imre.deak@intel.com> (raw)
In-Reply-To: <20210906182715.3915100-1-imre.deak@intel.com>

Atm the DPT object can accommodate only one VMA, so the VMA offset will
be always 0. Add an assert for this.
