6c2b7540 - accel/ivpu: Fix the NPU's DPU frequency calculation

Tue, 01 Apr 2025 15:59:11 +0000

accel/ivpu: Fix the NPU's DPU frequency calculationFix the frequency returned to the user space bythe DRM_IVPU_PARAM_CORE_CLOCK_RATE GET_PARAM IOCTL.The kernel driver returned CPU frequency for MTL and barePLL frequency for LNL - this was inconsistent and incorrectfor both platforms. With this fix the driver returns maximumfrequency of the NPU data processing unit (DPU) for all HWgenerations. This is what user space always expected.Also do not set CPU frequency in boot params - the firmwaredoes not use frequency passed from the driver, it was onlyused by the early pre-production firmware.With that we can remove CPU frequency calculation code.Show NPU frequency in FREQ_CHANGE interrupt when frequencytracking is enabled.Fixes: 8a27ad81f7d3 ("accel/ivpu: Split IP and buttress code")Cc: stable@vger.kernel.org # v6.11+Signed-off-by: Andrzej Kacprowski Signed-off-by: Maciej Falkowski Reviewed-by: Jeff Hugo Signed-off-by: Jacek Lawrynowicz Link: https://lore.kernel.org/r/20250401155912.4049340-2-maciej.falkowski@linux.intel.com List of files: /linux-6.15/include/uapi/drm/ivpu_accel.h

cd727221 - accel/ivpu: Add command buffer submission logic

Tue, 17 Jan 2023 09:27:22 +0000

accel/ivpu: Add command buffer submission logicEach of the user contexts has two command queues, one for compute engineand one for the copy engine. Command queues are allocated and registeredin the device when the first job (command buffer) is submitted fromthe user space to the VPU device. The userspace provides a list ofGEM buffer object handles to submit to the VPU, the driver resolvesbuffer handles, pins physical memory if needed, increments ref countfor each buffer and stores pointers to buffer objects inthe ivpu_job objects that track jobs submitted to the device.The VPU signals job completion with an asynchronous message thatcontains the job id passed to firmware when the job was submitted.Currently, the driver supports simple scheduling logicwhere jobs submitted from user space are immediately pushedto the VPU device command queues. In the future, it will beextended to use hardware base scheduling and/or drm_sched.Co-developed-by: Andrzej Kacprowski Signed-off-by: Andrzej Kacprowski Signed-off-by: Jacek Lawrynowicz Reviewed-by: Oded Gabbay Reviewed-by: Jeffrey Hugo Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-7-jacek.lawrynowicz@linux.intel.com List of files: /linux-6.15/include/uapi/drm/ivpu_accel.h
