I know, but I still wonder what it actually does. I've checked the first |
16 |
10 or so files in their list, and they all say in their header that they |
17 |
are under a free software license. So does that mean the license info in |
18 |
these files is wrong? If not, then why is the script touching them? |

Also, (e.g.) this: |

| announce MICROCODE_INTEL - "Intel microcode patch loading support" |
23 |
| reject_firmware arch/x86/kernel/cpu/microcode/intel.c |
24 |
| clean_blob arch/x86/kernel/cpu/microcode/intel.c |
25 |
| clean_blob arch/x86/events/intel/core.c |
26 |
| clean_kconfig arch/x86/Kconfig MICROCODE_INTEL |
27 |
| clean_mk CONFIG_MICROCODE_INTEL arch/x86/kernel/cpu/microcode/Makefile |

IIUC, it will disable CPU microcode updates. The code being removed is |
30 |
entirely free (but it could load some non-free third-party microcode). |
31 |
Do we really endorse that, from a security (spectre, meltdown, etc.) |
32 |
point of view? Note that the ex-factory microcode of these CPUs is |
33 |
already non-free, so arguably rejecting updates for it doesn't change |
34 |
anything. |
