Three 5W Intel Amber Lake Processors Coming Soon: Core m3-8100Y, Core i5-8200Y, Core i7-8500Y

When I talk about low power Intel processors, I usually think about atom-based families like Bay Trail, Cherry Trail, Apollo Lake or Gemini Lake with 2W to 10W processors that delivers entry-level performance at a reasonable price. But Intel has also been selling more powerful Core-m processors with a similar power budget, but with much better performance, at the cost of a significantly higher price tag. The company is now prepping to launch a new family of such processor with Amber Lake Y-series (aka Amber Lake-Y) family. Three Amber Lake processors are expected to be officially announced very soon: Core m3-8100Y dual core/quad thread processor @ 1.1 GHz (base) / 3.4 GHz (turbo) Core i5-8200Y dual core/quad thread processor @ 1.3 GHz (base) / 3.9 GHz (turbo) Core i7-8500Y dual core/quad thread processor @ 1.5 GHz (base) / 4.2 GHz (turbo) All three processors are manufactured with a 14 nm […]

Canonical Releases Ubuntu 16.04 LTS Certified for Intel NUC

In the x86 world, the theory is that you can take a single Linux distro image should work on any x86 compatible hardware. But for Atom-class processors however, including Bay Trail, Cherry Trail, Apollo Lake and Gemini Lake it has not always been the case, especially with features like audio output, Bluetooth, touchpad, and others. That’s why for example, Linuxium (Ian Morrison) decided to write isorepin.sh script in order to respin Ubuntu ISO images for such platforms and fix various issues. However, it appears Canonical and Intel have decided to take matters into their own hand, and have now released Ubuntu 16.04 LTS certified for Intel NUC mini PCs, kits, and boards for IoT deployment. Canonical made available both Ubuntu Desktop and Ubuntu Core images. Most supported devices are based on Intel 7th generation Intel Core processors: NUC7i5DNKPC Mini PC with Intel Core i5-7300U NUC7i3DNKTC Mini PC with Intel Core […]

Companies Address Concerns related to Speculative Execution Exploits: Meltdown and Spectre

Yesterday, news surfaced about a “bug” in Intel processors that could be fixed at the operating system level at the cost of a decrease in performance for some tasks, from a typical, and barely noticeable 5% hit, to a more consequent 30% hit for some specific tasks, and as we discussed yesterday I/O intensive tasks are the most impacted by the changes. While Intel (and Arm) are impacted, AMD claims not to be, and the issue was reported by major news outlets and likely impacting the stock price of the companies with Intel stock losing 3.39%, and AMD stock gaining 5.19%, so obviously every company felt the need to answer, starting with Intel’s response to security research findings: Recent reports that these exploits are caused by a “bug” or a “flaw” and are unique to Intel products are incorrect. Based on the analysis to date, many types of computing devices […]

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 […]

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, […]

Holo P2P Distributed Hosting is Powered by Holochain Technology, Leverages Holo Fuel Cryptocurrency (Crowdfunding)

The Internet is now mostly centralized, for example most people search with Google, and Facebook dominates the social media space in many countries. That also means access to content can easily be blocked by governments, and many companies will use your personal data to their benefits. Holo network promises to “take back the Internet” thanks to a P2P distributed web hosting system, where people hosts app from developers in their HoloPort devices, and get paid for hosting crypto apps in Holo Fuel cryptocurrency that can in turn be used to pay for processing power and/or storage on the network, or converted into other cryptocurrencies like Bitcoin, or fiat money (Dollars, Euros…). It’s like a new Internet that uses the current “pipes” (i.e. you’d still need Internet through your ISP), but all content would have to be created from the ground up. It basically aims to replace datacenters, websites, and app […]

MINIX based Intel Management Engine Firmware & UEFI are Closed Source & Insecure, NERF to the Rescue!

You may have heard a few things about Intel Management Engine in recent months, especially as security issues have been found, the firmware is not easily upgradeable, and the EFF deemed it a security hazard asking Intel for ways to disable it. In recent days, I’ve seen several media reports about the Management Engine being based on an Intel Quark x86-based 32-bit CPU running MINIX open-source operating system. Keep in mind, there’s nothing nefarious about MINIX, it’s just that Intel keeps its own developments on top closed. One of sources for the information is a blog post explaining how to disable Intel ME 11, but ZDNET also points to one of the talks at the Embedded Linux Conference Europe 2017 entitled “Replace Your Exploit-Ridden Firmware with Linux” by Ronald Minnich, Google which explains the problem, and proposes a solution to (almost) disable Intel’s ME, and replace UEFI by a small […]
