Hello Xiao,

Added.

If you happen to know a table of "CPU implementer" for ARM (i.e. a
mapping of the number to the company), then I can easily add even
more :-))

Greetings

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!

You can see the list of currently assigned implementer codes in the
description of the MIDR_EL1 register[0] in the Arm developer
documentation.

Hello Punit,

Thanks a lot, I added those, should greatly improve detection on Arm.
Interestingly, though, the recently reported "Phytium" is not on the
list. (Which what this report was initially about)

Greetings

Indeed, I noticed it too after sending the mail. Sorry, I don't know
what's going on there. Probably need somebody from Arm.com to add their
2c.

Hello Punit,

I don't think we need to bother, the current state is now vastly
improved, and I take Phytium as a "bonus".

Greetings
