Wed, 15 May 2024 11:30:05 +0000

accel/ivpu: Split IP and buttress codeThe NPU device consists of two parts: NPU buttress and NPU IP.Buttress is a platform specific part that integrates the NPU IP withthe CPU.NPU IP is the platform agnostic part that does the inference.This separation enables support for multiple platforms usinga single NPU IP, so for example NPU IP 37XX could be integrated intoMTL and LNL platforms.Signed-off-by: Wachowski, Karol Signed-off-by: Jacek Lawrynowicz Link: https://patchwork.freedesktop.org/patch/msgid/20240515113006.457472-3-jacek.lawrynowicz@linux.intel.com List of files: /linux-6.15/drivers/accel/ivpu/Makefile

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/drivers/accel/ivpu/Makefile
