Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

Linux 6.3 release – Notable changes, Arm, RISC-V and MIPS architectures

Linux Torvalds has just announced the release of Linux 6.3 on the Linux Kernel Mailing List (LKML): It’s been a calm release this time around, and the last week was really no different. So here we are, right on schedule, with the 6.3 release out and ready for your enjoyment. That doesn’t mean that something nasty couldn’t have been lurking all these weeks, of course, but let’s just take things at face value and hope it all means that everything is fine, and it really was a nice controlled release cycle. It happens. This also obviously means the merge window for 6.4 will open tomorrow. I already have two dozen pull requests waiting for me to start doing my pulls, and I appreciate it. I expect I’ll have even more when I wake up tomorrow. But in the meantime, let’s enjoy (and test) the 6.3 release. As always, the shortlog […]

Linux 6.2 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.2 has just been released with Linus Torvalds making the announcement on LKML as usual: So here we are, right on (the extended) schedule, with 6.2 out. Nothing unexpected happened last week, with just a random selection of small fixes spread all over, with nothing really standing out. The shortlog is tiny and appended below, you can scroll through it if you’re bored. Wed have a couple of small things that Thorsten was tracking on the regression side, but I wasn’t going to apply any last-minute patches that weren’t actively pushed by maintainers, so they will have to show up for stable. Nothing seemed even remotely worth trying to delay things for. And this obviously means that the 6.3 merge window will open tomorrow, and I already have 30+ pull requests queued up, which I really appreciate. I like how people have started to take the whole “ready for […]

Linux 6.1 LTS release – Main changes, Arm, RISC-V and MIPS architectures

Linus Torvalds announced the release of Linux 6.1, likely to be an LTS kernel, last Sunday: So here we are, a week late, but last week was nice and slow, and I’m much happier about the state of 6.1 than I was a couple of weeks ago when things didn’t seem to be slowing down. Of course, that means that now we have the merge window from hell, just before the holidays, with me having some pre-holiday travel coming up too. So while delaying things for a week was the right thing to do, it does make the timing for the 6.2 merge window awkward. That said, I’m happy to report that people seem to have taken that to heart, and I already have two dozen pull requests pending for tomorrow in my inbox. And hopefully I’ll get another batch overnight, so that I can try to really get as […]

Linux 5.18 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.18 is out! Linus Torvalds has just announced the release on lkml: No unexpected nasty surprises this last week, so here we go with the 5.18 release right on schedule. That obviously means that the merge window for 5.19 will open tomorrow, and I already have a few pull requests pending. Thank you everybody. I’d still like people to run boring old plain 5.18 just to check, before we start with the excitement of all the new features for the merge window. The full shortlog for the last week is below, and nothing really odd stands out. The diffstat looks a bit funny – unusually we have parsic architecture patches being a big part of it due to some last-minute cache flushing fixes, but that is probably more indicative of everything else being pretty small. So outside of the parisc fixes, there’s random driver updates (mellanox mlx5 stands out, […]

Samsung UFS 4.0 storage to offer up to 4,200 MB/s read speeds, 1TB capacity

Samsung Electronics has unveiled its first Universal Flash Storage (UFS) 4.0 solution based on the company’s 7th-generation V-NAND and a proprietary controller allowing speeds of up to 23.2 gigabits per second (Gbps) per lane or double the previous UFS 3.1 solutions. In more practical terms, Samsung UFS 4.0 storage will deliver a sequential read speed of up to 4,200 MB/s and a sequential write speed of 2,800 MB/s, corresponding to about 2x and 1.6x faster speeds over UFS 3.1 storage. Samsung also claims that power efficiency has been enhanced with a sequential read speed of up to 6.0 MB/s per milliampere (mA), or about a 46-percent improvement over UFS 3.1. An advanced Replay Protected Memory Block (RPMB) is integrated into the chip to store important personal data that can only be read or written through authenticated access, and whose design is said to be 1.8 times more efficient. Samsung UFS […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]

UCIe (Universal Chiplet Interconnect Express) open standard for Chiplets with heterogeneous chips

We first heard about Chiplet, chips that gather IP or chips from different vendors into a single chip, in 2020 with the now-defunct zGlue’s Open Chiplet Initiative, but the term recently came back to the forefront last month with Intel’s investment into the “Open Chiplet Platform” that aims to offer a modular approach to chip design through chiplets with each block/chiplet customized for a particular function. It turns out there’s now an official standard called the Universal Chiplet Interconnect Express (UCIe) whose specification defines the interconnect between chiplets within a package, and not only backed by Intel, but also AMD, Arm, ASE, Google Cloud, Meta, Microsoft, Qualcomm, Samsung, and TSMC. UCIe defines the Physical Layer (Die-to-Die I/O) and protocols to be used for the chiplet interfaces, currently PCIe and CXL (Compute Express Link), but more protocols will be added to the specification in the future. The goal is to provide […]
