I aslo didn't know it now. But I just look the kernel source code, I find the file arch/arm/include/asm/cputype.h It has some infos about " implemented processors or cores". From line 61: #define ARM_CPU_IMP_ARM 0x41 #define ARM_CPU_IMP_BRCM 0x42 #define ARM_CPU_IMP_DEC 0x44 #define ARM_CPU_IMP_INTEL 0x69 I has one Raspberry Pi 4 Model B Rev 1.5， it's linuxinfo output is: Linux raspberrypi 5.15.32-v8+ #1538 SMP PREEMPT Thu Mar 31 19:40:39 BST 2022 Four ARM processors, 864.00 total bogomips, 3794M RAM System library 2.31.0 The last core info of /proc/cpuinfo file is: processor : 3 BogoMIPS : 108.00 Features : fp asimd evtstrm crc32 cpuid CPU implementer : 0x41 CPU architecture: 8 CPU variant : 0x0 CPU part : 0xd08 CPU revision : 3 "CPU implementer : 0x41" and "CPU part : 0xd08" match the line in arch/arm/include/asm/cputype.h: #define ARM_CPU_PART_CORTEX_A72 0x4100d080 CC to debian-arm@lists.debian.org , welcome to discuss. Welcome to supply more infos for arm CPU implementers. Thanks! xiao sheng wen(肖盛文)
