accel/ivpu: Add support for userptr buffer objects

2025-10-30T07:52:51Z

Introduce a new ioctl `drm_ivpu_bo_create_from_userptr` that allows users to create GEM buffer objects from user pointers to memory regions. The user pointer must be page-aligned and the memory region must remain valid for the buffer object's lifetime. Userptr buffers enable direct use of mmapped files (e.g. inference weights) in NPU workloads without copying data to NPU buffer objects. This reduces memory usage and provides better flexibility for NPU applications.

accel/ivpu: Add coredump support

2024-10-11T10:44:38Z

Use coredump (if available) to collect FW logs in case of a FW crash. This makes dmesg more readable and allows to collect more log data.

accel/ivpu: Split IP and buttress code

2024-05-17T06:30:24Z

The NPU device consists of two parts: NPU buttress and NPU IP. Buttress is a platform specific part that integrates the NPU IP with the CPU. NPU IP is the platform agnostic part that does the inference. This separation enables support for multiple platforms using a single NPU IP, so for example NPU IP 37XX could be integrated into MTL and LNL platforms.

accel/ivpu: Share NPU busy time in sysfs

2024-05-15T05:42:29Z

The driver tracks the time spent by NPU executing jobs and shares it through sysfs `npu_busy_time_us` file. It can be then used by user space applications to monitor device utilization. NPU is considered 'busy' starting with a first job submitted to firmware and ending when there is no more jobs pending/executing.

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: Rename sources to use generation based names

2023-08-09T11:39:52Z

Given that VPU generation can be used by multiple platforms, driver should use VPU IP generation in names instead of a platform. Change naming for sources files. Use 37XX format, where: 3 - major VPU IP generation version 7 - minor VPU IP generation version XX - postfix indicating this is an architecture and not marketing name Signed-off-by: Jacek Lawrynowicz Reviewed-by: Stanislaw Gruszka Signed-off-by: Stanislaw Gruszka Reviewed-by: Jeffrey Hugo Link: https://patchwork.freedesktop.org/patch/msgid/20230731161258.2987564-2-stanislaw.gruszka@linux.intel.com
