35b13763 - accel/ivpu: Introduce a new DRM driver for Intel VPU

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

accel/ivpu: Introduce a new DRM driver for Intel VPUVPU stands for Versatile Processing Unit and it's a CPU-integratedinference accelerator for Computer Vision and Deep Learningapplications.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 componentsThis driver supports VPU IP v2.7 integrated into Intel Meteor Lakeclient 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 firmwareCo-developed-by: Krystian Pradzynski Signed-off-by: Krystian Pradzynski 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/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com List of files: /linux-6.15/drivers/accel/ivpu/Kconfig
