Intel Hardware Security Bug Fix to Hit Performance on Windows, Linux…

Many security bugs can be fixed without performance penalty , but according to reports Intel processors have a hardware bug – whose details have not been disclosed yet (embargo) – that seems to affect all operating systems including Windows, Linux, Mac OS, etc…, and the fix may lead to significant performance hits for some tasks. We know a bit more thanks to the Kernel Page Table Isolation (KPTI) patch for Linux that enables the fix/workaround with X86_BUG_CPU_INSECURE feature. The fix used to be called KAISER, and there’s an explanation on LWN about “hiding the kernel from user space” about the issue: On contemporary 64-bit systems, the shared address space does not constrain the amount of virtual memory that can be addressed as it used to, but there is another problem that is related to security. An important technique for hardening the system is kernel address-space layout randomization (KASLR), which randomizes […]

Year 2017 in Review, Top 10 Posts, and Some Fun Stats

2017 is coming to an end, and as I do every year, I’ll take a look back at the year that was on CNX Software. The pace of development boards launches has not slowed down this year, and we get an even wider range from the low-end with Orange Pi or NanoPi boards, to much more powerful ARM boards, and some new entrants like Libre Computer. The same is true for TV boxes, most of which now support 4K HDR, ranging from ultra cheap models selling for less than $20 to higher end Android TV boxes, while mini PCs were dominated by Intel Apollo Lake models, although some Cherry Trail products were also launched. Processor-wise, Amlogic launched more Amlogic S905X derivatives with S905W/S905D/S905Z, which are popular in the TV box market. Rockchip’s most interesting processor this year was RK3328 quad core Cortex A53 processor designed for 4K HDR Android TV […]

Grapeboard Raspberry Pi Lookalike Comes with Dual Gigabit Ethernet, Two USB 3.0 Ports

Scalys is a startup founded in 2016 in the Netherlands by Sintecs in order to provide advanced high-performance embedded system solutions for automotive-, avionics-, defence-, industrial-, medical and telecommunication industries.

Dune HD Unveils 5 Entry Level to Premium 4K HDR Linux + Android Media Players & Set-Top Boxes

Dune HD is known to make high-end digital media players that often costs several hundred dollars such as Sigma Designs based Dune HD SOLO 4K or Dune HD Solo Lite. The company has now sent out an email announcing new models classified into three categories with most models based on Amlogic processors: Neo Series – Entry level Dune HD Neo 4K – 4Kp60 HDR media player + Android Smart TV box Amlogic S905X 1GB RAM, 8GB flash 802.11ac Wi-Fi, 100Mbit Ethernet, Bluetooth Dune HD Neo 4K T2 – 4Kp60 HDR media player + Android Smart TV box + DVB-T/T2/C receiver Amlogic S905D 1GB RAM, 8GB flash 802.11ac Wi-Fi, 100Mbit Ethernet, Bluetooth Dune HD Neo 4K T2 Plus – 4Kp60 HDR media player + Android Smart TV box + DVB-T/T2/C receiver Amlogic S905D 2GB RAM, 16GB flash 802.11ac Wi-Fi, 100Mbit Ethernet, Bluetooth Sky series – Models with satellite receiver Dune HD […]

Orange Pi One Plus Allwinner H6 Board Launched for $20

Allwinner H6 is a processor designed for 4K HDR set-top boxes such as Zidoo H6 Pro, but with USB 3.0, Gigabit Ethernet, and PCIe interfaces, the processor is also a good candidate for ARM development boards where you need fast I/Os. I was expecting Orange Pi 3 Plus as the first board based on the processor, but instead Shenzhen Xunlong has just launched a cheaper Orange Pi One Plus version that sells for $19.99 plus shipping. Orange Pi One Plus specifications: SoC – Allwinner H6 V200 quad core Cortex A53 processor with Arm Mali-T720MP2 GPU System Memory – 1 GB LPDDR3 Storage – micro SD card slot up to 32GB Video & Audio Output – HDMI 2.0a up to 4K @ 60 Hz with HDR, HDCP, CEC Connectivity – Gigabit Ethernet (via Realtek RTL8211 transceiver) USB – 1x USB 2.0 host port, 1x micro USB OTG port Expansion – 26-pin […]

What’s the Best Android TV Box (2017/2018 Edition)?

Since I was often asked which TV box to buy, I wrote a guide entitled “What’s the best Android TV box?” in April 2016. Time has passed, new products have launched, I tested more devices, and got further reader feedback, so it’s time for an update. There’s still no device that rules them all, and since everybody has different requirements and price points, what could the best Android TV box ever to one person, maybe be a piece of junk to another. Before purchasing a TV box, you should consider what you plan to do with it, and find the device with matches your needs and budget. So first, I’ll provide a list of things to look for – beside the SoC/RAM selection – before selecting three TV boxes that stand out (in no particular order), as well as alternatives worth looking at. Things to Look for The list is […]

Renesas R-Car M3 Starter Kit is Designed for ADAS Applications

Most boards targeting the automotive market are impossible to purchase by individual, so last year I was pleasantly surprised when I discovered Renesas R-Car M2 Porter Linux automotive infotainment development board was available for sale on Digikey, and had good documentation on eLinux.org. The company has now introduced another automotive board, namely R-Car V3M starter kit, that’s not designed for infotainment, but instead for ADAS (Advanced Driver Assistance Systems) or even AD (Automated Driving) applications. Specifically, the board is supposed to “accelerate the development of New Car Assessment program (NCAP), front camera applications, surround view systems, and lidars” leveraging the company’s R-Car V3M image recognition SoC. Renesas R-Car V3M starter kit (V3MSK) specifications: SoC – Renesas R-Car V3M processor with two Cortex A53 64-bit cores @ up to 800 MHz, a dual lockstep Cortex-R7 32-bit core @ up to 800 MHz, IMP-X5-V3M image recognition engine System Memory – 448KB RAM on-chip; […]

Ubuntu 17.10 May Corrupt the BIOS on Some Lenovo, Acer, Dell, and Other Laptops

Canonical has decided to temporarily remove the download link to Ubuntu 17.10 due leaving a notice reading: The download of Ubuntu 17.10 is currently discouraged due to an issue on certain Lenovo laptops. Once fixed this download will be enabled again. The issue that many user are reported being unable to save BIOS settings or boot with USB in several Lenovo Laptops with many topics about this issue on Lenovo Forums. The installed operating system still boots normally, so many affected people may not have even noticed. Based on the bug report it seems to be related to the enablement of intel-spi-* drivers (Intel Serial Flash drive) in the kernel (CONFIG_SPI_INTEL_SPI_PCI option), and this could also affect Ubuntu 16.04 with HWE kernels. The fix is to disable the driver in the kernel, and Canonical will soon release images. The downside of not using the driver are likely null or minimal, […]
