Subject: [PATCH 0/7] Add a DRM driver to support AI Processing Unit (APU)
Date: Wed, 17 May 2023 16:52:30 +0200 [thread overview]
Message-ID: <20230517145237.295461-1-abailon@baylibre.com> (raw)
This adds a DRM driver that implements communication between the CPU and an
APU. The driver target embedded device that usually run inference using some
prebuilt models. The goal is to provide common infrastructure that could be
re-used to support many accelerators. Both kernel, userspace and firmware tries
to use standard and existing to leverage the development and maintenance effort.
The series implements two platform drivers, one for simulation and another one for
the mt8183 (compatible with mt8365).
For the people interested by the firmware or userspace library,
the sources are available here:
https://gitlab.baylibre.com/baylibre/libapu/libapu
The support of APU has to be upstreamed to libdrm.
Until this is done, you could find the source here:
https://gitlab.baylibre.com/baylibre/libapu/libdrm/-/tree/abailon/main
The driver for mt8183 depends on this series (which is currently blocked):
https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=620429
Alexandre Bailon (5):
drm: Add support of AI Processor Unit (APU)
drm/apu: Add memory allocator
drm/apu: Add support of requests
drm/apu: Add support of IOMMU
dt-bindings: Add bidings for mtk,apu-drm
Julien Stephan (2):
drm/apu: allow platform driver to implement their own mmap function
drm/apu: Add support for a simulated APU
