Year 2021 in review – Top 10 posts and statistics

As per tradition, we’ll look back at what happened during the year in the last post, and see what 2022 may have in store, plus the usual statistics from CNX Software website. The biggest story of 2021 has to be the worsening of semiconductors shortages with extremely long lead times, prices of some components going up multiple folds, constant complaints on Twitter about availability and prices. I think I even saw a website, hopefully misconfigured, showing an estimated availability of a specific STM32 MCU in 2037. This also gave rise to opportunities and board redesigns, with MotorComm Ethernet chips replacing some Realtek chips in SBCs such as NanoPi R2C and  Orange Pi R1S Plus LTS, and CH9102F showing up as a replacement for CP2104 in some IoT boards. We also got some interesting Arm processors, but sadly the high-expected Rockchip RK3588 got delayed by another year, although it’s getting really […]

ROC-RK3566-PC single board computer supports up to 8GB RAM, M.2 NVMe SSD’s

Firefly has now launched a Rockchip RK3566 single board computer named ROC-RK3566-PC, following the launch of Station P2 RK3568 mini PC on Indiegogo last March, and the completion of the campaign a few days ago. The quad-core Cortex-A55 SBC supports up to 8GB ECC memory, up to 128GB flash, M.2 2242 MVMe SSD’s, HDMI 2.0 and MIPI DSI video interfaces, Gigabit Ethernet, and more. ROC-RK3566-PC specifications: SoC – RockChip RK3566 quad-core Cortex-A55 @ up to 1.8GHz with Arm Mali-G52 2EE GPU with support for OpenGL ES 1.1/2.0/3.2. OpenCL 2.0. Vulkan 1.1, 0.8 TOPS NPU, 4Kp60 H.265/H.264/VP9 video decoder System Memory – 2GB, 4GB, or 8GB LPDDR4 RAM with support for “all-data-link ECC” (TBC: Because the info I have so far is that ECC is supported on RK3568, not on RK3566) Storage 32GB, 64GB, or 128GB eMMC flash M.2 PCIe 2.0 socket for M.2 2242 NVMe SSD MicroSD card slot Video […]

Linux 5.11 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has released Linux 5.11 just in time for… “Valentine’s Day”: Nothing unexpected or particularly scary happened this week, so here we are – with 5.11 tagged and pushed out. In fact, it’s a smaller-than-average set of commits from rc7 to final, which makes me happy. And I already have several pull requests lined up for tomorrow, so we’re all set for the merge window to start. But in the meantime – and yes, I know it’s Valentine’s Day here in the US – maybe give this release a good testing before you go back and play with development kernels. All right? Because I’m sure your SO will understand. Linus Last time around, Linux 5.10 was an LTS release that added EXT-4 performance enhancements, improved post-Spectre performance, as well as the enablement of BCM2711 (Raspberry Pi 4) display pipeline, among other many changes. Some of the notable changes in […]

Linux 4.16 Release – Main Changes, Arm and MIPS Architectures

Linus Torvalds has just released Linux 4.16: So the take from final week of the 4.16 release looks a lot like rc7, in that about half of it is networking. If it wasn’t for that, it would all be very small and calm. We had a number of fixes and cleanups elsewhere, but none of it made me go “uhhuh, better let this soak for another week”. And davem didn’t think the networking was a reason to delay the release, so I’m not. End result: 4.16 is out, and the merge window for 4.17 is open and I’ll start doing pull requests tomorrow. Outside of networking, most of the last week was various arch fixlets (powerpc, arm, x86, arm64), some driver fixes (mainly scsi and rdma) and misc other noise (documentation, vm, perf). The appended shortlog gives an overview of the details (again, this is only the small stuff in […]
