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 <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com
