Linux 5.0 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linux 5.0 Changelog

Linus Torvalds has just released Linux 5.0: Ok, so the last week of the 5.0 release wasn’t entirely quiet, but it’s a lot smaller than rc8 was, and on the whole I’m happy that I delayed a week and did an rc8. It turns out that the actual patch that I talked about in the rc8 release wasn’t the worrisome bug I had thought: yes, we had an uninitialized variable, but the reason we hadn’t immediately noticed it due to a warning was that the way gcc works, the compiler had basically initialized it for us to the right value. So the same thing that caused not the lack of warning, also effectively meant that the fix was a no-op in practice. But hey, we had other bug fixes come in that actually did matter, and the uninitialized variable _could_ have been a problem with another compiler. Regardless – all is well that ends well. We have more than a …

Samsung Galaxy S10, S10+, S10e, S10 5G Launched with Snapdragon 855 or Exynos 9820 SoC

Samsung Galaxy S10

Samsung officially launched the long awaited Galaxy S10 smartphone yesterday sporting either a Qualcomm Snapdragon 855 or Samsung Exynos 9820 processor coupled with 8GB RAM, 128 to 512GB storage, and a 6.1″ display. There are actually four variants of Galaxy S10, with S10+ model coming with up to 12GB RAM, 1TB flash storage, and a 6.4″ display, S10e phone with a smaller 5.8″ display, as low as 6GB RAM, and 128 to 256GB flash storage, and S10 5G with a 5G modem, a larger 6.7″ display, 6 cameras, and a larger 4,500 mAh battery. Many consider Samsung Galaxy phones to be the reference when it comes to Android phones, so let’s have a look at the technical specifications and features to see if there’s anything really new beside more processing power, and memory. Galaxy S10, S10+, S10e, and S10 5G phones share many of the same specifications: SoC (one or the other depending on market) Qualcomm Snapdragon 855 7nm 64-bit …

Samsung Exynos Auto V9 Octa-core Cortex A76 Processor Targets Automotive Infotainment Systems

Samsung Exynos Auto V9

Samsung Exynos processors are well known for their use in mobile processor, but the company has now announced their first automotive grade processor with Exynos Auto V9 SoC featuring eight Cortex A76 cores clocked at up to 2.1 GHz, a Mali G76 GPU, a HiFi 4 audio digital signal processor (DSP), an intelligent neural processing unit (NPU), and a safety island core that supports Automotive Safety Integrity Level (ASIL)-B standards. Exynos Auto V9 does not come with the latest Cortex-A76AE cores for autonomous driving, as instead the processor is specifically designed for in-vehicle infotainment (IVI) systems, and will be found in Audi cars starting in 2021. The processor also supports LPDDR4 and LPDDR5 DRAM, can control up to six independent displays and twelve cameras. Three separate sets of Mali G76 GPU cores will enable simultaneous support for the cluster display, central information display (CID) and rear-seat entertainment (RSE). The NPU will be used for features as a speech, gesture or …

Linux 4.20 Release – Main Changes, Arm and MIPS Architectures

Linux 4.20 Changelog

After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just try to keep to the normal merge window schedule, even …

An Attempt to Benchmark Entry-level x86 Boards against RK3399 & Exynos Arm Boards

Arm vs Intel C-Ray

Some Arm boards have become quite powerful, while hardware based on low power Intel processor has generally become cheaper with both architectures somewhat converging in terms of performance and price. Piotr Maliński got interested and purchased some low cost (<$150) Intel hardware to compare to mid-range Arm boards, throwing a Raspberry Pi 3 B+ into the mix as well for comparison. Those are the Intel test boards / computers: Qotom motherboard with Intel Atom Z3735F Bay Trail processor, 2GB RAM, 32GB flash – $74 + shipping on Aliexpress Piesia nano ITX board with Intel Celeron N2806 Bay Trail processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces – Piotr found it for around $85 on Aliexpress, but the price now jumped to over $150 plus shipping, which does not make it very attractive Generic thin mini ITX motherboard based on Celeron N3160 “Braswell” processor, DDR3 SO-DIMM socket, SATA / mSATA interfaces. $62.68 shipped on Aliexpress. MSI E350DM-E33 motherboard with “old” AMD E-350 …

ODROID-XU4 and ODROID-XU4Q Boards Going for $49 (Promo)

ODROID XU4 Black Friday

ODROID-XU4, and its fanless ODROID-XU4Q sibling, are neat little single board computer packing lots of power into a small form factor. I tested ODROID-XU4 with Ubuntu 18.04 recently and was relatively impressed by how well it worked considering it’s an Arm platform, as there were still admittedly some limitations. But as they say at $59 a board you can’t beat the price. Except you can actually do, as Hardkernel is offering both ODROID-XU4Q and ODROID-XU4 for just $49 during Black Friday here and there. If you’ve already forgotten about the board it is equipped with a Samsung Exynos 5422 octa-core Cortex A15/A7 processor, 2GB RAM, eMMC module support, Gigabit Ethernet, USB 3.0, HDMI 1.4, and more. You can read the full specifications here. The only difference between ODROID-XU4 and ODROID-XU4Q is the latter comes with a large heatsink, while the former is cooled by fan. If you are currently shopping for Black Friday and/or Cyber Monday, you’ll find more deals …
