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!
