From bcda3b66fa83619316614957d10cfa3eb5a38527 Mon Sep 17 00:00:00 2001 From: Joe Zheng Date: Sat, 8 Feb 2025 01:18:03 +0000 Subject: [PATCH] firmware: add package for Intel VPU/NPU firmware Intel NPU device is an AI inference accelerator integrated with Intel client CPUs, starting from Intel Core Ultra generation of CPUs (formerly known as Meteor Lake). It enables energy-efficient execution of artificial neural network tasks. The full device name is Neural Processing Unit, but the Linux kernel driver uses the older name - Versatile Processing Unit (VPU). This package is for NPU/VPU firmware. Details in https://github.com/intel/linux-npu-driver Intel VPU firmware is now part of linux-firmware. The current FW file names in linux-firmware do not match intel vpu driver, create links to fix it details in https://github.com/torvalds/linux/blob/master/drivers/accel/ivpu/ivpu_fw.c Signed-off-by: Joe Zheng Link: https://github.com/openwrt/openwrt/pull/17904 Signed-off-by: Robert Marko --- package/firmware/linux-firmware/intel.mk | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/package/firmware/linux-firmware/intel.mk b/package/firmware/linux-firmware/intel.mk index 32e16701495..1ec894e97ec 100644 --- a/package/firmware/linux-firmware/intel.mk +++ b/package/firmware/linux-firmware/intel.mk @@ -279,3 +279,15 @@ define Package/i915-firmware-gsc/install done endef $(eval $(call BuildPackage,i915-firmware-gsc)) + +Package/ivpu-firmware = $(call Package/firmware-default,Intel VPU firmware,,LICENSE.intel_vpu) +define Package/ivpu-firmware/install + $(INSTALL_DIR) $(1)/lib/firmware/intel/vpu + $(INSTALL_DATA) $(PKG_BUILD_DIR)/intel/vpu/*.bin $(1)/lib/firmware/intel/vpu + for t in `cd $(1)/lib/firmware/intel/vpu && ls vpu_*.bin | cut -d. -f1 | cut -d_ -f2 | sort | uniq`; do \ + source=`cd $(1)/lib/firmware && ls intel/vpu/vpu_$$$${t}_v*.bin | sort | tail -n1`; \ + target=$(1)/lib/firmware/vpu_$$$${t}.bin; \ + if [ -n "$$$$source" ]; then ln -sf $$$$source $$$$target; fi \ + done +endef +$(eval $(call BuildPackage,ivpu-firmware))
