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 […]

MediaTek Kompanio 520 and Kompanio 528 processors targets entry-level Chromebooks

MediaTek Kompanio 520 and Kompanio 528 octa-core Arm processors are designed for entry-level Chromebooks with all-day battery life and a display up to 2520 x 1080 resolutions. As time passes “entry-level” gets a new meaning as the new SoCs are equipped with two Cortex-A76 cores @ up to 2.2 GHz, six Cortex-A55 cores @ 2.0 GHz, and an Arm Mali-G52 GPU. That’s almost Rockchip RK3588 territory although not quite… MediaTek Kompanio 528 and 520 specifications: Octa-core CPU 2x Arm Cortex-A76 cores up to 2.2GHz (Kompanio 520 is limited to 2.0 GHz) 6x Arm Cortex-A55 cores up to 2GHz GPU – Arm Mali G52 MC2 2EE AI accelerator – Dual-core AI processing unit (APU) Memory – LPDDR4x up to 3733Mbps Storage – eMMC 5.1 flash with hardware command queue Display 2520 x 1080 @ 60Hz 1920 x 1080 @ 60Hz (Ext) Video Encoding – 1920 x 1080 @ 60fps H.264 or […]

Linux 6.0 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.0 has just been released by Linus Torvalds: So, as is hopefully clear to everybody, the major version number change is more about me running out of fingers and toes than it is about any big fundamental changes. But of course there’s a lot of various changes in 6.0 – we’ve got over 15k non-merge commits in there in total, after all, and as such 6.0 is one of the bigger releases at least in numbers of commits in a while. The shortlog of changes below is only the last week since 6.0-rc7. A little bit of everything, although the diffstat is dominated by drm (mostly amd new chip support) and networking drivers. And this obviously means that tomorrow I’ll open the merge window for 6.1. Which – unlike 6.0 – has a number of fairly core new things lined up. But for now, please do give this most […]

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, […]

AMD Ryzen 5000 C-Series processors target Chrome OS devices for work

AMD has just introduced the 15W Ryzen 5000 C-Series “Zen 3” processors for premium Chrome OS devices designed for work and collaboration. The processors can with up to eight cores and sixteen threads and are said to offer all-day battery life. AMD Ryzen 5000 C-Series processors for Chrome OS are expected to offer up to 67% faster responsiveness and up to 85% better graphics performance when comparing a Chromebook based on AMD Ryzen 7 5825C against an earlier model based on AMD Ryzen 7 3700C introduced in 2020 using respectively WebXPRT 3 and Motion Mark 1.2 benchmarks. Multitasking performance comparison using Geekbench 5 shows a 107% improvement that is probably mostly due to the doubling of the number of cores. The AMD Ryzen 5000 C-Series “”Barcelo” family is currently comprised of four parts. We can look at the Ryzen 7 5825C other features for more details: Cache – 512KB L1 […]

Android 13 developer preview released with privacy, security, and productivity improvements

Android 12 was only released in October 2021 and Google has already released the first developer preview of Android 13 with better privacy and security, efforts to improve developer productivity, and more work on better support for larger screens like tablets or Chromebooks building on the work done on Android 12L. Android 13 privacy and security features Google announces two new features related to privacy and security: Photo picker and APIs – Android 13 adds a system photo picker to share both local and cloud-based photos securely. Apps can use the photo picker APIs to access shared photos and videos without needing permission to view all media files on the device. So if an app just needs to access photos or videos, there’s no need to request full storage access. The photo picker will also be brought to through Google Play system updates on devices running Android 11 and higher, […]

Low-power Alder Lake-N processors coming to Chromebooks, embedded systems

Intel Alder Lake-N processors succeeding Jasper Lake processors are likely to soon show up in Chromebooks and embedded systems with early clues about the features of the upcoming processors found in the source tree of Coreboot and the Sound Open Firmware (SOF) Project. The person or team at Coelacanth’s dream has been analyzing the commits related to Alder Lake-N and found some interesting information related to the CPU cores, GPU, media capabilities, and peripherals, plus some reference boards by the Google Chromium team. Their latest update analyzes a partial boot log in the SOF Project and so far we know that: Alder Lake-N is an Atom-only “Gracemont” processor (no hybrid variant like Alder Lake-S desktop processors) with up to 8 threads/8 cores Alder Lake-N has two 4-core clusters that share the L2 cache The new processors should come with Intel UHD Gen12 graphics just like Alder Lake-P/M mobile processors, but […]
