tools: sof-kernel-log-check: filter out e1000e network error

This error was found in CML and TGL devices.

can we abstract the hardware address with the regexp?

[marc-hb]

@fredoh9 we don't need this since disabling built-in Ethernet in the BIOS, correct?

[marc-hb]

Re-open if needed.

[fredoh9]

This error happens occasionally. Ideally it should not happen as we disable built-in ethernet interface from the BIOS. Number of devices are keep growing and less people to manage all. I will re-open this for the review.

looks it matches fine. current filter is

• e1000e 0000:00:.+..+| en*: Hardware Error

I can slightly change REGEX like this too,

• e1000e [0-9a-fA-F]{4}:[0-9a-fA-F]{2}:[0-9a-fA-F]{2}.[0-9a-fA-F] en.+: Hardware Error
• e1000e 0000:00:[0-9a-fA-F]{2}.[0-9a-fA-F] en.+: Hardware Error

Wait a sec, UP Xtreme has two ethernet adapters, looks mostly problem in 1f.6 device. But we need more generic filter like above my suggestion. Will submit a fix shortly.

We can blocklist e1000e with Ansible instead, I just did that manually on sh-tglu-up-hda-05, see #564. No need to mess with BIOS anymore. Also, blocklist means anyone can still modprobe e1000e once if needed.

[marc-hb]

blocklist

[fredoh9]

blocklist

you mean blacklist?

[marc-hb]
