Good idea to print BIOS version |

| # 7 lines should be enough for all devices | ||
| sudo dmidecode | grep -A7 -i 'BIOS[[:blank:]]*Information' |

how about
sudo dmidecode -s bios-version

The output of -s is just one string.
I think I found something better: dmidecode -t 0

One line isn't enough?
$ sudo dmidecode -s bios-version
MTLPFWI1.R00.3424.D88.2311150537
-t 0 is too verbose to me
$ sudo dmidecode --type 0
# dmidecode 3.3
Getting SMBIOS data from sysfs.
SMBIOS 3.6 present.
# SMBIOS implementations newer than version 3.5.0 are not
# fully supported by this version of dmidecode.

This is only ~30 lines and I don't think anyone ever looks at the logs of this test except when there is something wrong.
As you can see, dmidecode reports multiple different versions: one at the top and another one or two at the bottom.
For instance https://sof-ci.01.org/softestpr/PR1161/build232/devicetest/index.html?model=CML_RVP_SDW-ipc3&testcase=verify-kernel-boot-log has 2 versions reported at the bottom.
The release date is also useful.
I agree we don't care about the stuff in the middle but I'd like to keep both versions and to keep the sof-test code very simple and robust.
We have other, unusable test logs with many thousands of lines, so big they make the browser slow: thesofproject/sof#8761
So 30 lines is a very small problem in comparison.

We could drop all the stuff in the middle like this but it's brittle and IMHO not worth the risk.
sudo dmidecode -t 0 | grep -v -e $'\t'Characteristics -e ^$'\t'$'\t' # bashism
