In my system (intel): |
| 15 |
|
| 16 |
$ iucode_tool -S |
| 17 |
iucode_tool: system has processor(s) with signature 0x000906e9 |
| 18 |
$ iucode_tool -L /lib/firmware/intel-ucode | grep 0x000906e9 -B 1 |
| 19 |
microcode bundle 18: /lib/firmware/intel-ucode/06-9e-09 |
| 20 |
018/001: sig 0x000906e9, pf_mask 0x2a, 2017-04-06, rev 0x005e, size 97280 |
| 21 |
018/002: sig 0x000906e9, pf_mask 0x2a, 2017-04-06, rev 0x005e, size 97280 |
| 22 |
|
| 23 |
So in this example "intel-ucode/06-9e-09" is what you'll write in the |
| 24 |
kernel form. |
| 25 |
|
| 26 |
There is a amd-ucode dir in /lib/firmware, so I assume it will be the same. |
