A customer found their machine being hung during reboot. A vmcore was collected. The vmcore analysis shown that the reboot sequence was stuck with tasks waiting for TTY to be unlocked after Scroll Lock was pressed. The customer came back demanding a workaround. Our reply was something like "press Scroll Lock again to unlock the TTY". I wonder what comes next.

If you think working as a Senior Principal in the Kernel team is fun, think twice.

#FOSDEM 2024 will be happening in a bit more than 1 week in Brussels!

Catch my talk "From phone hardware to mobile Linux" on Saturday morning or "Open Source for Sustainable and Long lasting Phones" (together with @agnes007 in the big Janson room!) on Sunday afternoon!

Or come by the @postmarketOS (+friends) stand in the AW building!

I hope to see you there!

Snowless winter in Himalayas – another sign of climate change

Many years ago, my father set out to create a book that would help new spinal-cord-injury victims come to terms with (and love) their new life. The result, called Options, was widely distributed in rehabilitation centers for years and helped thousands of people before finally going out of print.

Inspired by the creation of the Full Circle film, which quotes extensively from the book, we have been working to bring Options back. Now, we're happy to say that Options is available, under the Creative Commons SA 4.0 license, in a number of forms. Enjoy!

As an aside, I have to say that the tools for scanning and OCR work have gotten pretty good. All of this was made possible by SANE, unpaper, tesseract, Sphinx, and surely some other tools I'm forgetting now.

Folks, I can't take this on. If you want to take it on, I'll give advice.

Linux v6.8-rc1 comes with new document describing coding style for DTS (Devicetree sources):
https://www.kernel.org/doc/html/latest/devicetree/bindings/dts-coding-style.html

This marks the end of many unwritten rules, varying between subsystems and maintainers. At least, like with every coding style document, in theory. :)

@conor @nathanchance

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 :)

Bryan O'Donoghue and and Hans de Goede will be presenting "A fully open source stack for MIPI cameras" at FOSDEM on Saturday 3rd February at 13:30 in UD2.120 (Chavanne) as part of the Embedded Mobile and Automotive Devroom.

Released picolibc version 1.8.6 today.
Highlights: ctype avoids a static array, fenv functions are inlined (except on x86).
Full release notes here: https://github.com/picolibc/picolibc/releases/tag/1.8.6

"mq-deadline doesn't scale!" complaints are apparently rampant, so I spent a bit of time looking into that and wrote a few patches to address the basics. 100+% improvement, obviously the complaints were right.

Now waiting for folks to poke holes in it.

@jejb @corbet yeah, although Linus @torvalds himself is in the US, he barely has any power these days.

After 4 years the strlcpy() API has been fully removed from the Linux kernel. Long live strscpy().

Next up, strncpy()!

@monsieuricon LMK if you need any help, we've moved to b4/public-inbox/patchwork in a handful of places and it's been really great.

The @kicad Fund Drive bar is already at 10% with $10576 donated, keep it coming :)

"We estimate the supply-side value of widely-used OSS is $4.15 billion, but that the demand-side value [replacement value for each firm that uses the software] is much larger at $8.8 trillion. We find that firms would need to spend 3.5 times more on software than they currently do if OSS did not exist."
