Hi, This patchset contains a new Linux* Kernel Driver for Intel® VPUs. VPU stands for Versatile Processing Unit and it is an AI inference accelerator integrated with Intel non-server CPUs starting from 14th generation. VPU enables efficient execution of Deep Learning applications like object detection, classification etc. The whole driver is licensed under GPL-2.0-only except for two headers imported from the firmware that are MIT licensed. User space stack is open source and available at: - UMD driver: https://github.com/intel/linux-vpu-driver - Compiler and OpenVINO plugin: https://github.com/openvinotoolkit/vpux-plugin The firmware for the VPU will be distributed as a closed source binary in the UMD driver repo. This is hopefully the last revision of the patchset with minor changes outlined below. Regards, Jacek Changelog v6: - Remove userptr ioctl as it will be probably replaced with dma-buf heaps - Added dependency on !UML - Simplify struct file_operations ivpu_fops definition - Fixed compilation issues in patch 4 and 6 - Updated TODO v5: https://lore.kernel.org/all/20230109122344.253994-1-jacek.lawrynowicz@xxxxxxxxxxxxxxx/ - Rename ivpu_drm.h to ivpu_accel.h - Cleanup ivpu_mmu_config_check() - Optimize locking in ivpu_mmu_cd_add() - Invalidate user context if it has MMU faults - Move ivpu_ipc_match_consumer() outside ivpu_ipc_dispatch() v4: https://lore.kernel.org/all/20221208110733.5498-1-jacek.lawrynowicz@xxxxxxxxxxxxxxx/ - Switch to the accel framework (DRIVER_COMPUTE_ACCEL) - Move the driver from drivers/gpu/drm to drivers/accel - Rename kconfig DRM_IVPU option to DRM_ACCEL_IVPU and update dependencies - Create context on open() instead of lazy allocating it - Remove status_offset from submit ioctl, as status is now reported in bo_wait ioctl - Use managed resources in ivpu_drv.c - Optimize locking in ivpu_ipc.c - add new rx_msg_lock for consumer msg list - Refactor vpu_hw_mtl_reg.h to use BIT_MASK() and GENMASK() macros - Use module_pci_driver() for mudule init - Remove mutex from "struct ivpu_pm_info" - Add explicit "vdev" arg to ivpu_dbg() - Use drm_WARN_ON() instead of WARN_ON() where possible - Add comments for boot related functions - Update firmware API headers v3: https://lore.kernel.org/all/20220924151149.323622-1-jacek.lawrynowicz@xxxxxxxxxxxxxxx/ - Fixed alignment warning in ivpu_ipc.c when building with W=1 v2: https://lore.kernel.org/all/20220913121017.993825-1-jacek.lawrynowicz@xxxxxxxxxxxxxxx/ - Rename the driver from "drm/vpu" to "drm/ivpu" - Add a TODO file - Add support for WC buffers v1: https://lore.kernel.org/all/20220728131709.1087188-1-jacek.lawrynowicz@xxxxxxxxxxxxxxx/ Jacek Lawrynowicz (7): accel/ivpu: Introduce a new DRM driver for Intel VPU accel/ivpu: Add Intel VPU MMU support accel/ivpu: Add GEM buffer object management accel/ivpu: Add IPC driver and JSM messages accel/ivpu: Implement firmware parsing and booting accel/ivpu: Add command buffer submission logic accel/ivpu: Add PM support MAINTAINERS | 9 + drivers/Makefile | 1 + drivers/accel/Kconfig | 2 + drivers/accel/Makefile | 3 + drivers/accel/ivpu/Kconfig | 15 + drivers/accel/ivpu/Makefile | 16 + drivers/accel/ivpu/TODO | 11 + drivers/accel/ivpu/ivpu_drv.c | 654 +++++++++++++++ drivers/accel/ivpu/ivpu_drv.h | 190 +++++ drivers/accel/ivpu/ivpu_fw.c | 423 ++++++++++ drivers/accel/ivpu/ivpu_fw.h | 38 + drivers/accel/ivpu/ivpu_gem.c | 753 +++++++++++++++++ drivers/accel/ivpu/ivpu_gem.h | 127 +++ drivers/accel/ivpu/ivpu_hw.h | 170 ++++ drivers/accel/ivpu/ivpu_hw_mtl.c | 1084 +++++++++++++++++++++++++ drivers/accel/ivpu/ivpu_hw_mtl_reg.h | 280 +++++++ drivers/accel/ivpu/ivpu_hw_reg_io.h | 115 +++ drivers/accel/ivpu/ivpu_ipc.c | 510 ++++++++++++ drivers/accel/ivpu/ivpu_ipc.h | 93 +++ drivers/accel/ivpu/ivpu_job.c | 614 ++++++++++++++ drivers/accel/ivpu/ivpu_job.h | 67 ++ drivers/accel/ivpu/ivpu_jsm_msg.c | 169 ++++ drivers/accel/ivpu/ivpu_jsm_msg.h | 23 + drivers/accel/ivpu/ivpu_mmu.c | 883 ++++++++++++++++++++ drivers/accel/ivpu/ivpu_mmu.h | 50 ++ drivers/accel/ivpu/ivpu_mmu_context.c | 398 +++++++++ drivers/accel/ivpu/ivpu_mmu_context.h | 50 ++ drivers/accel/ivpu/ivpu_pm.c | 329 ++++++++ drivers/accel/ivpu/ivpu_pm.h | 38 + drivers/accel/ivpu/vpu_boot_api.h | 349 ++++++++ drivers/accel/ivpu/vpu_jsm_api.h | 999 +++++++++++++++++++++++ include/uapi/drm/ivpu_accel.h | 306 +++++++ 32 files changed, 8769 insertions(+) create mode 100644 drivers/accel/Makefile create mode 100644 drivers/accel/ivpu/Kconfig create mode 100644 drivers/accel/ivpu/Makefile create mode 100644 drivers/accel/ivpu/TODO create mode 100644 drivers/accel/ivpu/ivpu_drv.c create mode 100644 drivers/accel/ivpu/ivpu_drv.h create mode 100644 drivers/accel/ivpu/ivpu_fw.c create mode 100644 drivers/accel/ivpu/ivpu_fw.h create mode 100644 drivers/accel/ivpu/ivpu_gem.c create mode 100644 drivers/accel/ivpu/ivpu_gem.h create mode 100644 drivers/accel/ivpu/ivpu_hw.h create mode 100644 drivers/accel/ivpu/ivpu_hw_mtl.c create mode 100644 drivers/accel/ivpu/ivpu_hw_mtl_reg.h create mode 100644 drivers/accel/ivpu/ivpu_hw_reg_io.h create mode 100644 drivers/accel/ivpu/ivpu_ipc.c create mode 100644 drivers/accel/ivpu/ivpu_ipc.h create mode 100644 drivers/accel/ivpu/ivpu_job.c create mode 100644 drivers/accel/ivpu/ivpu_job.h create mode 100644 drivers/accel/ivpu/ivpu_jsm_msg.c create mode 100644 drivers/accel/ivpu/ivpu_jsm_msg.h create mode 100644 drivers/accel/ivpu/ivpu_mmu.c create mode 100644 drivers/accel/ivpu/ivpu_mmu.h create mode 100644 drivers/accel/ivpu/ivpu_mmu_context.c create mode 100644 drivers/accel/ivpu/ivpu_mmu_context.h create mode 100644 drivers/accel/ivpu/ivpu_pm.c create mode 100644 drivers/accel/ivpu/ivpu_pm.h create mode 100644 drivers/accel/ivpu/vpu_boot_api.h create mode 100644 drivers/accel/ivpu/vpu_jsm_api.h create mode 100644 include/uapi/drm/ivpu_accel.h -- 2.34.1
