Loongson 2K1000LA dual-core LoongArch processor powers industrial SBCs and IoT gateways

Banana Pi BPI-5202 Loongson 2K1000LA SBC

Loongson 2K1000LA is a 1GHz dual-core 64-bit LoongArch processor designed for industrial applications with gigabit Ethernet, SATA, two PCIe interfaces, two digital video outputs, audio interfaces, USB 2.0, and others all in a 1 to 5W power envelop. It is found in Loongson’s own development board and Banana Pi BPI-5020 2K1000LA SBC. The LoongArch architecture was first introduced in 2021 as an alternative to Arm, x86, and RISC-V, and heavily inspired by MIPS with extra instructions.  Some of the first LoongArch processors were the Loongson 3A5000 and 3C5000 SoCs for desktop computers and servers respectively, and now, the company has launched a lower-power processor for industrial applications, such as IoT gateways, with the 2K1000LA. Loongson 2K1000LA specifications We only have some basic specifications from the product page on Loongson’s website.; CPU – 2x 64-bit LoongArch cores clocked at 1GHz FPU – 128-bit vector unit Cache 32KB L1 instruction cache 32KB […]

Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.8 release

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

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

Linux 6.5 release

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

Linux 6.0 Release

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

Linux 5.17 changelog

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 […]

Linux 5.16 Release – Main Changes, Arm, RISC-V and MIPS architectures

Linux 5.16 release

Linus Torvalds has just announced the release of Linux 5.16: Not a lot here since -rc8, which is not unexpected. We had that extra week due to the holidays, and it’s not like we had lots of last-minute things that needed to be sorted out. So this mainly contains some driver fixes (mainly networking and rdma), a cgroup credential use fix, a few core networking fixes, a couple of last-minute reverts, and some other random noise. The appended shortlog is so small that you might as well scroll through it. This obviously means that the merge window for 5.17 opens tomorrow, and I’m happy to say I already have several pending early pull requests. I wish I had even more, because this merge window is going to be somewhat painful due to unfortunate travel for family reasons. So I’ll be doing most of it on the road on a laptop […]

Linux 5.14 Release – Main changes, Arm, MIPS, and RISC-V architectures

Linux 5.14 release

Linus Torvalds has just announced Linux 5.14 release which happens to almost coincide with the anniversary of the initial announcement of the “small” project on August 25, 1991, about 30 years ago. Here’s Linux 5.14’s announcement: So I realize you must all still be busy with all the galas and fancy balls and all the other 30th anniversary events, but at some point you must be getting tired of the constant glitz, the fireworks, and the champagne. That ball gown or tailcoat isn’t the most comfortable thing, either. The celebrations will go on for a few more weeks yet, but you all may just need a breather from them. And when that happens, I have just the thing for you – a new kernel release to test and enjoy. Because 5.14 is out there, just waiting for you to kick the tires and remind yourself what all the festivities are […]

Loongson’s first LoongArch processors – 3A5000 for computers, 3C5000L for servers

Loongson 3A5000

Loongson has officially launched the first processors based on LoongArch CPU instruction set architecture designed for made-in-China SoCs without the need to license technology made outside of China. Loongsoon LS3C5000L  (3C5000L) 16-core server processor clocked at up to 2.5 GHz is now official and is apparently comprised of four LS3A5000 (3A5000) LoongArch processors designed for desktop computers and laptops. Loongson 3A5000 CnTechPost reports Loongson 3A5000 quad-core 64-bit GS464V processor runs at 2.3GHz-2.5GHz. GS464V microarchitecture comes with four fixed-point units, two 256-bit vector operations units, and two access memory units. The processor also includes two 64-bit DDR4-3200 controllers with ECC checksum support, as well as four HyperTransport 3.0 controllers with multi-processor data consistency support. Performance-wise, Loongson 3A5000 is said to achieve 26+ points in the single-core and floating-point SPEC CPU2006 benchmarks, and over 80 in the multi-core version of the benchmarks. That’s about 50 percent higher performance than the previous pin-compatible […]
