Building on Intel Raptor Lake fails

[linouxis9]

I would say it's an issue detecting the CPU features as forcing the TARGET=HAWELL make it work? Thanks!

Ubuntu 22.04, on Intel i5-13500, with gcc-11:

Looks like it is missing a -mavx2 among the compiler options although HAVE_AVX2 was set automatically - and indeed INTEL_UNKNOWN,CORE_PRESCOTT suggests the CPUID was not recognized (beyond realizing that it is some Haswell-ish Intel cpu). Do you get this with a recent version (freshly released 0.3.22 or at least 0.3.21) ?

[linouxis9]

I got this error with the develop branch cloned 2 hours ago. I would guess that the newly added check for Raptor Lake is missing a few cpu ids?

[martin-frbg]

Looks like it. Currently it knows about family 6, model 7, extended model 11 only. What's the /proc/cpuid output of yours ?

Indeed, mine is model 15. If that's fine with you, I could compile the list of Raptor Lake's cpuids and open a PR to add them?

CPU 0:
   vendor_id = "GenuineIntel"
   version information (1/eax):
      processor type  = primary processor (0)
      family          = 0x6 (6)
      model           = 0xf (15)
      stepping id     = 0x2 (2)
      extended family = 0x0 (0)
      extended model  = 0xb (11)
      (family synth)  = 0x6 (6)
      (model synth)   = 0xbf (191)
      (simple synth)  = Intel (unknown model)

[martin-frbg]

That would be great (I wonder if there are more of them, or if this is "only" another case of desktop vs. mobile version)

I would guess it's because it's not the same die? i5 13500 is also a desktop chip, like the i7 13700k in this PR (#3800)
I found the full list here: https://edc.intel.com/content/www/us/en/design/products/platforms/details/raptor-lake-s/13th-generation-core-processors-datasheet-volume-1-of-2/003/cpuid/
I'll do the PR this afternoon, thanks for your help tracking down the problem!!

Should be TARGET=HASWELL
