amd-ucode/README

   1 This repository includes microcode container files for family 15h, 16h,
   2 17h, and 19h AMD CPUs. Microcode patches for families earlier than 15h are
   3 included in the microcode_amd.bin microcode container file. The microcode
   4 patches included in an AMD CPU microcode container file can be listed using
   5 the script in the following git repository:

  48 NOTE: For Genoa (Family=0x19 Model=0x11) and Bergamo (Family=0x19 Model=0xa0),
  49 either AGESA version >= 1.0.0.8 OR a kernel with the following commit is
  50 required:
  51 a32b0f0db3f3 ("x86/microcode/AMD: Load late on both threads too")
  52
  53 When late loading the patches for Genoa or Bergamo, there may be one spurious
  54 NMI observed per physical core. These NMIs are benign and don't cause any
  55 functional issue but will result in kernel messages being logged.
  56
  57 NOTE: When running 5.19+ kernels on Genoa or Bergamo systems, some microcode
  58 patches are known to trigger warnings in the PMI handler. The following are
  59 the required minimum patch levels to address this problem:
