AIC100 is a PCIe adapter card that hosts a dedicated machine learning inference accelerator. Regarding the open userspace (see the documentation patch), the UMD and compiler are a week or so away from being posted in the indicated repos. Just need to polish some documentation. The previous version (RFC) can be found at: https://lore.kernel.org/all/1660588956-24027-1-git-send-email-quic_jhugo@quicinc.com/ v2: -Addressed comments from RFC -Reduced the code to the core minimum by dropping telemetery, etc -Conversion to accel subsystem -Dropped versioning -Add mhi_qaic_cntl component -Restructure the documentation -Pull in a few fixes from the downstream tree Jeffrey Hugo (7): accel/qaic: Add documentation for AIC100 accelerator driver accel/qaic: Add uapi and core driver file accel/qaic: Add MHI controller accel/qaic: Add control path accel/qaic: Add datapath accel/qaic: Add qaic driver to the build system MAINTAINERS: Add entry for QAIC driver Pranjal Ramajor Asha Kanojiya (1): accel/qaic: Add mhi_qaic_cntl Documentation/accel/index.rst | 1 + Documentation/accel/qaic/aic100.rst | 498 +++++++++ Documentation/accel/qaic/index.rst | 13 + Documentation/accel/qaic/qaic.rst | 169 +++ MAINTAINERS | 8 + drivers/accel/Kconfig | 1 + drivers/accel/Makefile | 1 + drivers/accel/qaic/Kconfig | 23 + drivers/accel/qaic/Makefile | 13 + drivers/accel/qaic/mhi_controller.c | 576 +++++++++++ drivers/accel/qaic/mhi_controller.h | 19 + drivers/accel/qaic/mhi_qaic_ctrl.c | 586 +++++++++++ drivers/accel/qaic/mhi_qaic_ctrl.h | 11 + drivers/accel/qaic/qaic.h | 321 ++++++ drivers/accel/qaic/qaic_control.c | 1656 +++++++++++++++++++++++++++++ drivers/accel/qaic/qaic_data.c | 1952 +++++++++++++++++++++++++++++++++++ drivers/accel/qaic/qaic_drv.c | 771 ++++++++++++++ include/uapi/drm/qaic_accel.h | 283 +++++ 18 files changed, 6902 insertions(+) create mode 100644 Documentation/accel/qaic/aic100.rst create mode 100644 Documentation/accel/qaic/index.rst create mode 100644 Documentation/accel/qaic/qaic.rst create mode 100644 drivers/accel/qaic/Kconfig create mode 100644 drivers/accel/qaic/Makefile create mode 100644 drivers/accel/qaic/mhi_controller.c create mode 100644 drivers/accel/qaic/mhi_controller.h create mode 100644 drivers/accel/qaic/mhi_qaic_ctrl.c create mode 100644 drivers/accel/qaic/mhi_qaic_ctrl.h create mode 100644 drivers/accel/qaic/qaic.h create mode 100644 drivers/accel/qaic/qaic_control.c create mode 100644 drivers/accel/qaic/qaic_data.c create mode 100644 drivers/accel/qaic/qaic_drv.c create mode 100644 include/uapi/drm/qaic_accel.h
