Subject: [PATCH 1/2] drm/panfrost: Consider dma-buf imported objects as resident
Date:   Sat, 25 Nov 2023 20:52:02 +0000
Message-ID: <20231125205438.375407-2-adrian.larumbe@collabora.com>

A GEM object constructed from a dma-buf imported sgtable should be regarded
as being memory resident, because the dma-buf API mandates backing storage
to be allocated when attachment succeeds.
