Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures

Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend.  Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a […]

A first look at Allwinner D1 Linux RISC-V SBC and Processor

Last year, we reported that Allwinner was working on an Alibaba XuanTie C906 based RISC-V processor that would be found in low-cost Linux capable single board computers selling for as low as $12. The good news is that we won’t have to wait much longer as Allwinner D1 RISC-V processor is slated for an announcement next week, and a business card-sized SBC, also made by Allwinner, will become available in May. Some of the information is already available to developers in China, and CNX Software managed to obtain information about the Linux RISC-V SBC and Allwinner D1 processor. Allwinner D1 development board Let’s check out the board first which comes with the following specifications: SoC – Allwinner D1 single-core XuanTie C906 64-bit RISC-V processor @ 1.0 GHz with HiFi4 DSP, G2D 2D graphics accelerators Memory – 1GB DDR3 memory Storage – 256MB SPI NAND flash, MicroSD card slot Video Output […]

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 […]

Orange Pi Zero2 Allwinner H616 SBC runs Android 10 or Linux

Last year, Shenzhen Xunlong Software unveiled Orange Pi Zero2 SBC as an update to the popular Orange Pi Zero board with a faster Allwinner H6 processor, HDMI 2.0 video output, USB 3.0 port, Gigabit Ethernet, and WiFi. Just one little problem: AFAIK they never sold it. But Orange Pi Zero2 board is now back with another design features instead equipped with a newer Allwinner H616 processor supporting Android 10, and various Linux distributions such as Ubuntu and Debian. Orange Pi Zero2 (2020) specifications: SoC – Allwinner H616 quad-core Arm Cortex-A53 processor @ up to 1.5 GHz with Arm Mali G31 MP2 GPU with support for OpenGL ES 3.2 and OpenCL 2.0 Memory – 512MB or 1GB DDR3 Storage – 2MB SPI flash and MicroSD card slot Video Output Micro HDMI 2.0a port up to 4Kp60 Video composite (CVBS) via 13-pin header (See Expansion section) Video Decoding 10-bit H265/HEVC up tp […]

PineCube open-source Linux IP camera devkit launched for $30

Pine64 has been a busy company/community with the launch of Linux powered Arm development boards, PinePhone smartphone, PineTab tablet, and Pinebook Pro laptop in the last two years. They also had other smaller projects that got fewer resources due to the launch of the aforementioned products and COVID-19 induced delays, and one of those is PineCube open-source IP camera development kit that finally launched for $29.99 plus shipping. PineCube hardware specifications: SoC – Allwinner/Sochip S3 Arm Cortex-A7 processor @ 800MHz with 128MB in-package DDR3 RAM Storage – 128Mbit SPI Nor Flash and MicroSD slot, both bootable Camera – 5MP OV5640 sensor Audio – Built-in microphone, speaker Display – Optional 4.5-inch RGB LCD screen ( Networking – 10/100M Ethernet with passive PoE and WiFi USB – USB 2.0 Type-A host port Expansion – 26-pin GPIO header Misc – Volume and home buttons Power Supply 5V/1A via micro USB port or GPIO […]

Linux 5.9 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.9 on lkml: Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for. The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere). Outside of that, the most visible thing is a reinstatement of the fbdev amba-clcd driver – that’s a noticeable patch, but it’s basically just mainly a revert. The rest is really really tiny (mostly some other minor driver updates, but some filesystem and architecture fixes […]

Debian based Mobian Linux OS Brings Librem 5 Phosh Shell to Pinephone

2020 is the year of the Linux phone. Sort of… At least, we now have smartphones that ships with Linux thanks to PinePhone and Librem 5, and several Linux mobile operating systems with Ubuntu Touch based UBPorts, postmarketOS, and others. Mobian is another Linux distribution which as its name implies is based on Debian and targets mobile devices. Interestingly, the project relies on Purism Phosh phone shell/user interface used in Librem 5, but the first Mobian image has been released for PinePhone with plans for PineTab and Librem 5 support coming later. Mobian supports a nice list of apps include Chromium, Firefox ESR, Calls, Files, Telegram messaging app, MPV media player, GNOME 2048, and more 3D graphics works, you can make phone calls, browse the web, and use GPS/GNSS applications, but it’s still work in progress as for example, USB and the camera does not work, the phone may take […]

Linux 5.7 Released – Main Changes, Arm, MIPS and RISC-V Architectures

OK… I’m a bit late on that one. Linus Torvalds released Linux 5.7 last week: So we had a fairly calm last week, with nothing really screaming “let’s delay one more rc”. Knock wood – let’s hope we don’t have anything silly lurking this time, like the last-minute wifi regression we had in 5.6.. But embarrassing regressions last time notwithstanding, it all looks fine. And most of the discussion I’ve seen the last week or two has been about upcoming features, so the merge window is now open  and I’ll start processing pull requests tomorrow as usual. But in the meantime, please give this a whirl. We’ve got a lot of changes in 5.7 as usual (all the stats look normal – but “normal” for us obviously pretty big and means “almost 14 thousand non-merge commits all over, from close to two thousand developers”), So the appended shortlog is only […]
