@T_X Not everyone has some spare money for engineers full time salary in non-profit way... They already have such updated kernels, just on their website, not on kernel.org. Your suggestion would benefit community, but what would be the benefit of this to Canonical?

First Linux Kernel beer in Zurich organized with @Andi was a success - many beers were drunk. :) Stay in touch for more events!

Once you see it, you cannot unsee:

+#ifndef MSM_VIDC_EMPTY_BRACE
+#define MSM_VIDC_EMPTY_BRACE {},
+#endif
...
+static const struct of_device_id msm_vidc_dt_match[] = {
+	{.compatible = "..."},
...
+	MSM_VIDC_EMPTY_BRACE
+};

We are back to the past! To year 2000-something to be precise. This reminds me ARM Mali Linux kernel drivers which were using MALI_SUCCESS instead of return 0.

Anyone from Samsung has some inputs on Qualcomm minidump solution? Without any feedback we'll assume Samsung is fine with Qualcomm's choices. Thread:

Just a regular reminder that the war isn't over, civilians are still murdered in their homes by cruise missiles, and war crimes are committed daily by the invasion force occupying the sovereign territory of Ukraine.

Until the 1991 borders are restored, all war criminals are in jail, and reparations are paid off, I will continue to #StandWithUkraine, and so should you.

Oh, the amazing construction of silosed Business Units of big corporations. When interacting with Open Source communities, one team in some Business Unit of that company cannot learn from the past experience of some other team, because they are silosed. Separate. Thus this team makes the same mistakes other teams already did. However Open Source community sees it differently - one company sending contributions with the same mistakes. It is always okay to make a mistake, but making the same mistake again and again, is a bit waste of our time.

Trying to sell something on Facebook marketplace: 99% of interested people are scammers. I found a pervert joy in playing with them, requiring rather small effort from my side and ending in some amusement. This one gave up just after two days off wasting his time.

Go Beavers! I mean, the true beavers, the greatest ecosystem engineers, which are vital in bringing diversity, richness, and healing degraded landscapes. “Beaver settlements triple in 15 years in Switzerland” https://www.swissinfo.ch/eng/beavers-increase-threefold-in-15-years-in-switzerland/48657934

If you want to learn more, why beavers are important, I recommend Andrew Millison’s: https://youtu.be/43bmtqKDhBE

With v6.5-rc1 merge window, my remaining few fixes for Samsung Exynos SoC dtbs_check compliance were merged. This means that with v6.5-rc1 all ARM and ARM64 Samsung Exynos SoC Devicetree sources (DTS) pass in-kernel Devicetree bindings compliance tests. I can finally enable a builder testing mainline DTS for this:
https://krzk.eu/#/builders/92
https://krzk.eu/#/builders/91
https://github.com/krzk/tools/commit/743f694cfe4d18dd5f92728967aa762edd59c84e

P.S. The ARM64 Exynos DTS was actually compliant since v6.3-rc1, so that part I could have enabled earlier.

Is fixing the same issue over and over again, and expecting it to be fixed, also definition of insanity? Or just Groundhog Day? Or Whack-A-Mole game?

Hey @linuxfoundation
Do you plan to upload more photos of EOSS 2023? I see pictures from only the first two days of EOSS, not even complete two days... Other days are not uploaded at all. As you can see in the link below, count stays at 150 pictures is since last Thursday:

10% of commits in Linux kernel v6.4 came from Linaro engineers. It is a nice result for such a small group of kernel engineers.

It was great to see at the EOSS 2023 commitments from some ARM64 SoC manufacturers to upstreaming their SoCs. It was visible in the conference talks but also I got such clear vibes during the talks behind the scenes.
What was a bit missing is a story of Qualcomm which recently is heavily visible upstream - both directly and through the Qualcomm Landing Team in Linaro. November last year Qualcomm released its newest, shiniest mobile SoC: the Snapdragon 8 Gen 2 (SM8550).
And guess what happened? The next day you could find all the Linux kernel support for this new SoC on the mailing list. The newest SoC was released with upstream support at the same time. There is also story from @superna9999: https://www.linaro.org/blog/upstream-linux-support-now-available-for-the-the-qualcomm-snapdragon-8-gen-2-mobile-platform/

Updating my CV, collecting references, debt register extract, salary details and writing motivation letter. People do crazy stuff to get a nice apartment in Switzerland.

I love it. And think how many other equations and laws of physics can be improved with adding AI. Ohm's law? Dude, please, I = (V + AI) / R. Newton's second law? Easy peasy, F = m * a * AI. Maxwell equations - don't get me even started...

So it began...

That was quite nice Devicetree source snippet. Can be entirely incorrect though, just looks good.
