晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

This repository includes microcode container files for family 15h, 16h,
17h, and 19h AMD CPUs. Microcode patches for families earlier than 15h are
included in the microcode_amd.bin microcode container file. The microcode
patches included in an AMD CPU microcode container file can be listed using
the script in the following git repository:
https://github.com/AMDESE/amd_ucode_info

The microcode patches included in the container files in this directory are
listed below:

NOTE: For Genoa (Family=0x19 Model=0x11) and Bergamo (Family=0x19 Model=0xa0),
either AGESA version >= 1.0.0.8 OR a kernel with the following commit is
required:
a32b0f0db3f3 ("x86/microcode/AMD: Load late on both threads too")

When late loading the patches for Genoa or Bergamo, there may be one spurious
NMI observed per physical core. These NMIs are benign and don't cause any
functional issue but will result in kernel messages being logged.

NOTE: When running 5.19+ kernels on Genoa or Bergamo systems, some microcode
patches are known to trigger warnings in the PMI handler. The following are
the required minimum patch levels to address this problem:

  Family=0x19 Model=0x11 Stepping=0x01: Patch=0x0a10113e
  Family=0x19 Model=0x11 Stepping=0x02: Patch=0x0a10123e
  Family=0x19 Model=0xa0 Stepping=0x01: Patch=0x0aa00116
  Family=0x19 Model=0xa0 Stepping=0x02: Patch=0x0aa00212
