Subject: [PATCH v3 17/20] drm/tegra: Set resv fields when importing/exporting GEMs
Date: Wed, 7 Oct 2020 20:12:35 +0300 [thread overview]
Message-ID: <20201007171238.1795964-18-mperttunen@nvidia.com> (raw)
In-Reply-To: <20201007171238.1795964-1-mperttunen@nvidia.com>
To allow sharing of implicit fences when exporting/importing dma_buf
objects, set the 'resv' fields when importing or exporting GEM
objects.
