Subject: [RFC PATCH 0/4] Add a DRM driver to support AI Processing Unit (APU)
Date: Fri, 17 Sep 2021 14:59:41 +0200 [thread overview]
Message-ID: <20210917125945.620097-1-abailon@baylibre.com> (raw)
This adds a DRM driver that implements communication between the CPU and an
APU.
This uses VirtIO buffer to exchange messages.
For the data, we allocate a GEM object and map it using IOMMU to make it
available to the APU.
The driver is relatively generic, and should work with any SoC implementing
hardware accelerator for AI if they use support remoteproc and VirtIO.
For the people interested by the firmware or userspace library,
the sources are available here:
https://github.com/BayLibre/open-amp/tree/v2020.01-mtk/apps/examples/apu
This RFC is a rewrite of a previous RFC that was not using DRM:
https://patchwork.kernel.org/project/linux-remoteproc/cover/20200930115350.5272-1-abailon@baylibre.com/
