accel/ivpu: Add NPU profiling support

2024-05-15T05:42:23Z

Implement time based Metric Streamer profiling UAPI. This is a generic mechanism allowing user mode tools to sample NPU metrics. These metrics are defined by the FW and transparent to the driver. The user space can check for this feature by checking DRM_IVPU_CAP_METRIC_STREAMER driver capability.

accel/ivpu: Add job status for jobs aborted by the driver

2024-02-06T12:37:34Z

Add DRM_IVPU_JOB_STATUS_ABORTED to indicate that the job was aborted by the driver due to e.g. TDR or user context MMU faults. This will help UMD and tests distinguish if job was aborted by the FW or the driver.

accel/ivpu: Deprecate DRM_IVPU_PARAM_CONTEXT_PRIORITY param

2024-01-22T09:31:54Z

DRM_IVPU_PARAM_CONTEXT_PRIORITY has been deprecated because it has been replaced with DRM_IVPU_JOB_PRIORITY levels set with submit IOCTL and was unused anyway.

accel/ivpu: Remove support for uncached buffers

2023-11-08T15:27:39Z

Usages of DRM_IVPU_BO_UNCACHED should be replaced by DRM_IVPU_BO_WC. There is no functional benefit from DRM_IVPU_BO_UNCACHED if these buffers are never mapped to host VM. This allows to cut the buffer handling code in the kernel driver by half. Usage of DRM_IVPU_BO_UNCACHED buffers was removed from user-space driver and will not be part of first UMD release.

accel/ivpu: Refactor memory ranges logic

2023-08-09T11:52:15Z

Add new dma range and change naming convention for virtual address memory ranges managed by KMD. New available ranges are named as follows: * global range - global context accessible by FW * aliased range - user context accessible by FW * dma range - user context accessible by DMA * shave range - user context accessible by shaves * global shave range - global context accessible by shave nn Signed-off-by: Karol Wachowski Reviewed-by: Stanislaw Gruszka Signed-off-by: Stanislaw Gruszka Link: https://patchwork.freedesktop.org/patch/msgid/20230731161258.2987564-6-stanislaw.gruszka@linux.intel.com

accel/ivpu: Extend get_param ioctl to identify capabilities

2023-08-09T11:48:56Z

Add DRM_IVPU_PARAM_CAPABILITIES parameters to get_param ioctl to query driver capabilities. For now use it for identify metric streamer and new dma memory range features. Currently upstream version of intel_vpu does not have those, they will be added it the future.

accel/ivpu: Add command buffer submission logic

2023-01-19T10:12:00Z

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 GEM buffer object management

2023-01-19T10:11:34Z

Adds four types of GEM-based BOs for the VPU: - shmem - internal - prime All types are implemented as struct ivpu_bo, based on struct drm_gem_object. VPU address is allocated when buffer is created except for imported prime buffers that allocate it in BO_INFO IOCTL due to missing file_priv arg in gem_prime_import callback. Internal buffers are pinned on creation, the rest of buffers types can be pinned on demand (in SUBMIT IOCTL). Buffer VPU address, allocated pages and mappings are released when the buffer is destroyed. Eviction mechanism is planned for future versions.
