English (US)   So I followed Paul Mundt into this narrow alley...  -  Categories: Announcements [A]  -  @ 11:15:47 am

Back from Japan at last (I think United lost my sleep schedule on the way home though, trying to retrieve it this weekend has been a challenge).

Both KS and JLS went well I thought. It was really good to connect with some of the Japanese developers that until now I’ve only interacted with through email.

The summit went well this year I thought. We didn’t have a big set of controversial issues to discuss, but we did sort out some development process issues. The highlight for me was the two customer panels. On the first day we had some people from TV and other vendors talk about how they’re using the kernel and other open source software. It’s interesting that some of them are stuck way back on 2.4 and very early 2.6 kernels. Part of the reason is long product development cycles, but mostly it’s because the SoCs used in many products only have support in a limited set of kernels (usually custom patches for specific kernels provided by companies like Montavista). The “platformization” work done by tglx and the x86 team recently (partly motivated by Intel “Moorestown” support, but also in preparation for more x86 based SoCs in the future) should help with this for x86 stuff. We definitely want to avoid an ARM-like situation where each SoC requires a specific kernel with incompatible firmware and hardware support. I had some good discussions with Linus and Paul on that topic; the tricky part will be ensuring that vendors adhere to some level of standardization in their platform and firmware support. Doing so will have big benefits: upstream kernel support should be better and much more flexible (good for the SoC vendors and their customers), and the platform maintainers should have a much easier job integrating support for new platforms without a huge set of ifdefs and incompatible firmware interfaces. Managed to get a few bugs fixed at KS as well, Ted & Dirk didn’t have anywhere to run when I wanted them to test some patches for problems they’d reported!

The JLS conference was interesting too, with a few good talks on things like barcode delivery of oops info and btrfs

Tokyo is a pretty amazing city. This was my first trip to Japan and a few of us were fortunate enough to have Paul Mundt guide us for a couple of evenings to explore the city. The narrow alleyways and tiny bars in the Shinjuku (at least I think that’s where we ended up) were really fun. We even checked out a Mexican bar called Bonita; Mexican stuff outside the southwest US and Mexico is always interesting, but the Japanese mix made things even more so. Overall a fun night including Japanese Denny’s food, passed out salarymen, and an everything store with some bizarre costumes, including some furry outfits we were tempted to buy… A bit later in the week we had a contrasting experience by going to Seamon (one of the dozens of one star Michelin sushi restaurants in Tokyo) and a high end scotch and cigar bar afterwards.

Ok now back to catching up on the huge backlog of patches that have accrued due to travel neglect.
