Otherwise, I occupy my time with various bits in RISC-V land.

Decided to pick up Baldurs Gate 3, even if the D&D style shit is lost on save scumming auld me, but I am really loving the voice acting. Of course the fact that there's a bunch of Irish accents is biasing me, but it feels like one of the best parts of the game :)

Today's interesting discovery is that the c908 on the k230 (despite not really advertising it) supports Zicbom and the T-Head custom CMO stuff.
Apparently the Chinese documentation says it supports it but the English documentation just says "RISC-V Base Cache Management Operation ISA Extensions Version 1.0-rc2-2c97b28, 2021-11-05: Frozen.". In comparison, about a third of the user manual talks about the T-Head CMOs.
edit: I realise it is expected that the document would cover the custom stuff in far more detail, but for the other standard extensions it claims to support, it at least mentions that it supports the instruction and what it does.

Made for an interesting conversation on IRC with dramforever, revy and cyy this afternoon :)

@monsieuricon @vbabka ngl, reading that it makes me want a "b4 summarise v(N-1) -P <whatever is the dt-binding patch>!

Adding U-Boot support for the replacement riscv extension DT properties, come to find out that the extension detection there is completely broken, at least in QEMU.
It expects the ISA string to be 32 characters or less, probably true for all hardware it supports but untrue in QEMU for a long time. I guess there aren't too many ISA string parsers, but I do wonder how many others are broken in the face of the "fancier" strings.

Ywe Caerlyn is my favourite poster on lkml. I have no idea what this is meant to be, but it is great:

Whenever I read Nathan Chancellors recaps I always go and look at what
my contributions look like (see https://nathanchance.dev/posts/2023-cbl-retrospective/
for his far more comprehensive retrospective than my own brief look).
In 2023 this is what they looked like:
Authored: 123
Reported: 8
Tested: 29
Acked: 412
Reviewed: 372
In comparison, 2022 looked like:
Authored: 181
Reported: 21
Tested: 28
Acked: 45
Reviewed: 92
Two rather different years in terms of my kernel contributions, that's
for sure. In March or April I started co-maintaining dt-bindings, which
is the reason for the massive growth in terms of ack/review tags.
The number that is there is probably also underselling the amount of
reviewing actually done, since I usually avoid leaving a tag on vN of a
patch when one of the other maintainers already has, even if I spent a
bunch of time reviewing v(N-1).
On another note, the number of reported-by tags dropped considerably - I
like to chalk that up to the riscv port becoming more stable :)

Being in my 20s, I was confused as to why YouTube keeps showing me adverts for toys for young children. I realised all I watch on this particular computer is videos about programming and 10+ year old MMOs and it all started to make a lot of sense.

@monsieuricon @a1ba there were plenty of younger developers at LPC, some significant contributors, sounds like it is time for current maintainers to start recruiting some of them as subsystem reviewers or co-maintainers!

Reading some patch discussion today (between two experienced developers/maintainers) and one cracked out a "I believe the kids these days would say '"Say you don't understand the
code without saying you don't understand the code."'
lmao, good one chief
code without saying you don't understand the code."'

I announced it before on social.kernel.org, mailing lists and finally in the Linux kernel (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c25223cba5aa9a536392933782d4a7df71d9093b). So one more time, same announcement:
None of the Samsung and Samsung Foundry platforms can bring any new `dtbs_check W=1` warning.
Contributor can easily test it, so sending code which introduces such warnings is considered close to sending code which does not compile. Fast step to get your maintainer grumpy.
