Linux 6.7 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 6.7 release

Linus Torvalds has just announced the release of Linux 6.7, following Linux 6.6 LTS a little over two months ago: So we had a little bit more going on last week compared to the holiday week before that, but certainly not enough to make me think we’d want to delay this any further. End result: 6.7 is (in number of commits: over 17k non-merge commits, with 1k+ merges) one of the largest kernel releases we’ve ever had, but the extra rc8 week was purely due to timing with the holidays, not about any difficulties with the larger release. The main changes this last week were a few DRM updates (mainly fixes for new hw enablement in this version – both amd and nouveau), some more bcachefs fixes (and bcachefs is obviously new to 6.7 and one of the reasons for the large number of commits), and then a few random […]

Linux 5.19 Release – Main changes, Arm, RISC-V and MIPS architectures

Linux 5.19 release arm risc-v mips

Linus Torvalds has just announced the release of Linux 5.19. It should be the last 5.xx version, with Linux 6.0 coming for the next cycle: So here we are, one week late, and 5.19 is tagged and pushed out. The full shortlog (just from rc8, obviously not all of 5.19) is below, but I can happily report that there is nothing really interesting in there. A lot of random small stuff. In the diffstat, the loongarch updates stand out, as does another batch of the networking sysctl READ_ONCE() annotations to make some of the data race checker code happy. Other than that it’s really just a mixed bag of various odds and ends. On a personal note, the most interesting part here is that I did the release (and am writing this) on an arm64 laptop. It’s something I’ve been waiting for for a _loong_ time, and it’s finally reality, […]

Linux 5.2 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.2 Changelog

Linus Torvalds announced the release of Linux 5.2 last Sunday: So I was somewhat pre-disposed towards making an rc8, simply because of my travels and being entirely off the internet for a few days last week, and with spotty internet for a few days before that [*]. But there really doesn’t seem to be any reason for another rc, since it’s been very quiet. Yes, I had a few pull requests since rc7, but they were all small, and I had many more that are for the upcoming merge window. Part of it may be due to the July 4th week, of course, but whatever – I’ll take the quiet week as a good sign. So despite a fairly late core revert, I don’t see any real reason for another week of rc, and so we have a v5.2 with the normal release timing. There’s no particular area that stands […]

Linux 5.1 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.1 Changelog

Linus Torvalds has just announced the release of Linux 5.1: So it’s a bit later in the day than I usually do this, just because I was waffling about the release. Partly because I got some small pull requests today, but mostly just because I wasn’t looking forward to the timing of this upcoming 5.2 merge window. But the last-minute pull requests really weren’t big enough to justify delaying things over, and hopefully the merge window timing won’t be all that painful either. I just happen to have the college graduation of my oldest happen right smack dab in the middle of the upcoming merge window, so I might be effectively offline for a few days there. If worst comes to worst, I’ll extend it to make it all work, but I don’t think it will be needed. Anyway, on to 5.1 itself. The past week has been pretty calm, […]

Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

Linux 4.19 Changelog

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so […]

96-Core NanoPi Fire3 Boards Cluster is a DIY Portable Solution to Teach or Develop Distributed Software

96-Core NanoPi Fire3 Cluster

Nick Smith has been messing around with clusters made of Arm boards for several years starting with Raspberry Pi boards, including a 5-node RPI 3 cluster, before moving to other boards like Orange Pi 2E, Pine A64+, or NanoPC-T3. His latest design is based on twelve NanoPi Fire3 boards with 8 cores each, bringing the total number of cores to 96.  The platform may not be really useful for actual HPC applications due to limited power and memory, but can still be relied upon for education and development, especially it’s easily portable. Nick also made some interesting points and discoveries. It’s pretty with shiny blinking LEDs, and what looks like proper cooling, and the cluster can deliver 60,000 MFLOPS with Linpack which places it in the top 250 faster computers in the world! That’s provided we travel back in time to year 2000 through 🙂 By today’s standard, it would […]

FriendlyElec Launches Smart6818 Samsung S5P6818 CPU Module

Smart4418 S5P4418 SoM Development Kit

Yesterday, we covered Core4418 low profile board based on Samsung S5P4418 quad core Cortex A9 processor, but that’s not the only product launched by FriendlyElec this week, as the company also introduced Smart6818, a Samsung S5P6818 CPU module following Smart4418 module design, and equipped with 1GB DDR3, and 8 to 32 GB eMMC flash. Smart6818 specifications: SoC – Samsung S5P6818 octa core Cortex A53 processor @ up to 1.4GHz, Arm Mali-400MP GPU System Memory – 1GB DDR3 up to 800 MHz Storage – 8GB eMMC flash (16GB and 32GB optional) Connectivity – Realtek RTL8211E Gigabit Ethernet transceiver Audio – ES8316 Audio codec Board to Board Headers 2x 70-pin 2.0mm pitch headers with RGB LCD, LVDS, HDMI Tx, I2C, PWM, USB host, UART, SPI, GPIOs, SDIO, Gigabit Ethernet, Audio input/output, Camera I/F 1x 34-pin 2.0mm pitch unpopulated header with GPIOs, MIPI CSI, ADC, PWM Power Supply – 5V Power Management – […]

FriendlyELEC Core4418 is a Low Profile Samsung S5P4418 Board

Core4412-LCD-Display

Samsung (Nexell) S5P4418 & S5P6818 quad/octa core Cortex A9 processors used to have dismal Linux support with a very old & unsecure Linux 3.4 kernel, but in the last year or so software support has greatly improved, likely because those processors are used in some Samsung Artik IoT modules. FriendlyELEC has been manufacturing several S5P boards starting from their NanoPi2 board launched in 2015, and more recently they introduced NanoPi Fire2A & Fire3 boards based on S5P4418 & S5P6818 processor respectively. But this month, they’ve launched two more S5P platforms, and today I’ll look at Core4418 board, which has a lower profile than any of their previous board since the RJ45 Ethernet jack and USB type A ports are not included. FriendlyELEC Core4418 specifications: SoC – Samsung S5P4418 quad core Cortex A9 processor @ up to 1.4GHz, Arm Mali-400MP GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash, […]
