Hi, it looks like this driver belongs into driver/accel. Best regards Thomas Am 17.05.23 um 16:52 schrieb Alexandre Bailon:
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 .../devicetree/bindings/gpu/mtk,apu-drm.yaml | 38 ++ drivers/gpu/drm/Kconfig | 2 + drivers/gpu/drm/Makefile | 1 + drivers/gpu/drm/apu/Kconfig | 22 + drivers/gpu/drm/apu/Makefile | 10 + drivers/gpu/drm/apu/apu_drv.c | 282 +++++++++ drivers/gpu/drm/apu/apu_gem.c | 230 +++++++ drivers/gpu/drm/apu/apu_internal.h | 205 ++++++ drivers/gpu/drm/apu/apu_sched.c | 592 ++++++++++++++++++ drivers/gpu/drm/apu/simu_apu.c | 313 +++++++++ include/uapi/drm/apu_drm.h | 81 +++ 11 files changed, 1776 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpu/mtk,apu-drm.yaml create mode 100644 drivers/gpu/drm/apu/Kconfig create mode 100644 drivers/gpu/drm/apu/Makefile create mode 100644 drivers/gpu/drm/apu/apu_drv.c create mode 100644 drivers/gpu/drm/apu/apu_gem.c create mode 100644 drivers/gpu/drm/apu/apu_internal.h create mode 100644 drivers/gpu/drm/apu/apu_sched.c create mode 100644 drivers/gpu/drm/apu/simu_apu.c create mode 100644 include/uapi/drm/apu_drm.h
