Subject: [PATCH 22/24] drm/virtio: implement blob resources: report blob mem to userspace
Date: Thu, 13 Aug 2020 19:39:58 -0700 [thread overview]
Message-ID: <20200814024000.2485-23-gurchetansingh@chromium.org> (raw)
In-Reply-To: <20200814024000.2485-1-gurchetansingh@chromium.org>
The stride field has never been used, so repurpose it to be
"blob_mem". This way, userspace can know the memory properties
of the blob if it's passed between userspace processes and
no suitable userspace API exists to transmit that knowledge.
