OK, got a bit of confusing output from the Intel microcode tool. SHould I go for the newest firmware (2015-08-02) or the highest revision?
| Code: |

As you can see, 67 offers a newer date by three days, but 68 offers a higher revision. Which should I be using?

| Code: | # iucode_tool -S -l /lib/firmware/intel-ucode/*
...
microcode bundle 170: /lib/firmware/intel-ucode/06-8e-09

172/001: sig 0x000806eb, pf_mask 0xc0, 2018-02-11, rev 0x0084, size 98304 |
Whatever signature "iucode_tool -S" tells you. |

OK, it just clicked. I thought that "-S" showed minimal info and then "-S -l" listed only compatible firmwares. I see now that the first shows me my signature and the second lists all it thinks are compatible, but I have to compare signatures. My thought process was that the latter command would only list firmware which would work, not which wouldn't.
