(This is a pretty complicated scenario, but we can try to make this work). Can you provide the output of cat /proc/device-tree/compatible and see if there is any PCI device that could help here to infer the SoC? I'll take care of the microarchitecture issue.

That file has: apple,j314sapple,t6000apple,arm-platform

t6000 is the code name of Apple Silicon SOC. You can find the detail here: https://github.com/AsahiLinux/docs/wiki/Codenames

Fastfetch uses:

switch (code)
{
    case 8103: return "Apple M1";
    case 6000: return "Apple M1 Pro";
    case 6001: return "Apple M1 Max";
    case 6002: return "Apple M1 Ultra";
    case 8112: return "Apple M2";
    case 6020: return "Apple M2 Pro";
    case 6021: return "Apple M2 Max";
    case 6022: return "Apple M2 Ultra";
    case 8122: return "Apple M3";
    case 6030: return "Apple M3 Pro";
    case 6031:
    case 6034: return "Apple M3 Max";
    default: return "Apple Silicon";
}

I've pushed a (bit crappy) fix in branch i263. Could you check if that works for you? Thanks for the feedback 👍

[RossComputerGuy]

It segfaults 😿

[RossComputerGuy]

get_soc seems to be borked.

0x0000000000418a68 in get_soc (cpu=0x4482d0) at src/arm/soc.c:1144
1144	    if(soc->soc_vendor == SOC_VENDOR_UNKNOWN) {
(gdb) p soc
$1 = (struct system_on_chip *) 0x0

[RossComputerGuy]

Seems read_file might've borked it:

Run till exit from #0  read_file (path=0x41ac10 "/proc/device-tree/compatible", len=0xffffffffc1bc) at src/common/udev.c:50
0x0000000000404588 in get_devtree_compatible () at src/common/udev.c:360
360	  if ((buf = read_file(_PATH_DEVTREE, &filelen)) == NULL) {
Value returned is $4 = 0x4574b0 "apple,j314s"

[Dr-Noob]

My bad! I have pushed a fix, what about now?

[RossComputerGuy]

Yeah, that works.

[RossComputerGuy]

Breakpoint 1, guess_soc_from_devtree (soc=0x455060) at src/arm/soc.c:917

Value returned is $1 = 0x4574b0 "apple,j314s"
(gdb) step
364	  return buf;

Seems read_file still isn't pulling the entire string.

[Dr-Noob]

Yeah, I was not careful with the NULL characters in the file. New patch, can you try again?

[RossComputerGuy]

Sweet, that works now.

Thanks, this is very useful. I have incorporated a similar (but less efficient) approach. Fastfetch is indeed a nice project! 👌

[Dr-Noob]

Sweet, that works now.

Awesome! I have merged this into master now. Thank you for your feedback and feel free to report more issues if you find any unsupported device around. It helps a lot 👍
