From 35b137630f08d913fc2e33df33ccc2570dff3f7d Mon Sep 17 00:00:00 2001 From: Jacek Lawrynowicz Date: Tue, 17 Jan 2023 10:27:17 +0100 Subject: accel/ivpu: Introduce a new DRM driver for Intel VPU VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. 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 components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client 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 firmware Co-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 --- drivers/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/Makefile') diff --git a/drivers/Makefile b/drivers/Makefile index bdf1c66141c9..f0972e2226c9 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -189,3 +189,4 @@ obj-$(CONFIG_COUNTER) += counter/ obj-$(CONFIG_MOST) += most/ obj-$(CONFIG_PECI) += peci/ obj-$(CONFIG_HTE) += hte/ +obj-$(CONFIG_DRM_ACCEL) += accel/ \ No newline at end of file -- cgit v1.2.3
