Subject: [PATCH 06/10] udmabuf: add MEMFD_CREATE dependency
Date: Tue, 11 Sep 2018 08:59:17 +0200 [thread overview]
Message-ID: <20180911065921.23818-7-kraxel@redhat.com> (raw)
In-Reply-To: <20180911065921.23818-1-kraxel@redhat.com>
udmabuf builds without it, but if userspace can not create memfd
handles in the first place it is rather pointless to include it.

A driver to let userspace turn memfd regions into dma-bufs.
Qemu can use this to create host dmabufs for guest framebuffers.
