accel/ivpu: Add support for delayed D0i3 entry message Currently the VPU firmware prepares for D0i3 every time the VPU is entering D0i2 Idle state. This is not optimal as we might not enter D0i3 every time we enter D0i2 Idle and this preparation is quite costly. This optimization moves D0i3 preparation to a dedicated message sent from the host driver only when the driver is about to enter D0i3 - this reduces power consumption and latency for certain workloads, for example audio workloads that submit inference every 10 ms. The VPU needs non zero time to enter IDLE state after responding to D0i3 entry message. If the driver does not wait for the VPU to enter IDLE state it could cause warm boot failures.

accel/ivpu: Add command buffer submission logic Each of the user contexts has two command queues, one for compute engine and one for the copy engine. Command queues are allocated and registered in the device when the first job (command buffer) is submitted from the user space to the VPU device. The userspace provides a list of GEM buffer object handles to submit to the VPU, the driver resolves buffer handles, pins physical memory if needed, increments ref count for each buffer and stores pointers to buffer objects in the ivpu_job objects that track jobs submitted to the device. The VPU signals job completion with an asynchronous message that contains the job id passed to firmware when the job was submitted. Currently, the driver supports simple scheduling logic where jobs submitted from user space are immediately pushed to the VPU device command queues. In the future, it will be extended to use hardware base scheduling and/or drm_sched.

accel/ivpu: Add Intel VPU MMU support VPU Memory Management Unit is based on ARM MMU-600. It allows the creation of multiple virtual address spaces for the device and map noncontinuous host memory (there is no dedicated memory on the VPU). Address space is implemented as a struct ivpu_mmu_context, it has an ID, drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that holds actual 3-level, 4KB page table. Context with ID 0 (global context) is created upon driver initialization and it's mainly used for mapping memory required to execute the firmware. Contexts with non-zero IDs are user contexts allocated each time the devices is open()-ed and they map command buffers and other workload-related memory. Workloads executing in a given contexts have access only to the memory mapped in this context. This patch is has two main files: - ivpu_mmu_context.c handles MMU page tables and memory mapping - ivpu_mmu.c implements a driver that programs the MMU device Co-developed-by: Karol Wachowski <karol.wachowski@linux.intel.com> Signed-off-by: Karol Wachowski <karol.wachowski@linux.intel.com> Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-3-jacek.lawrynowicz@linux.intel.com

accel/ivpu: Introduce a new DRM driver for Intel VPU VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. The VPU device consist of following components: - Buttress - provides CPU to VPU integration, interrupt, frequency and power management. - Memory Management Unit (based on ARM MMU-600) - translates VPU to host DMA addresses, isolates user workloads. - RISC based microcontroller - executes firmware that provides job execution API for the kernel-mode driver - Neural Compute Subsystem (NCS) - does the actual work, provides Compute and Copy engines. - Network on Chip (NoC) - network fabric connecting all the components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client CPUs (14th generation). Module sources are at drivers/accel/ivpu and module name is "intel_vpu.ko". This patch includes only very besic functionality: - module, PCI device and IRQ initialization - register definitions and low level register manipulation functions - SET/GET_PARAM ioctls - power up without firmware Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com
