Intel Mini PCs Linux Performance Comparison

Intel mini PC side-by-side comparison table

Recent vulnerabilities in Intel x86 microprocessors (Meltdown, Spectre, Foreshadow, RIDL, Fallout, ZombieLoad, etc.) are now addressed with mitigation patches for the Linux kernel although have resulted in some performance degradation. As a consequence, my previous comparison benchmarks could be somewhat misleading when compared with new results given the different versions of software at the time of execution. So I’ve repeated running my standard Phoronix Test Suite benchmarks on several of the latest mini PCs each running the latest updated Ubuntu 18.04.2 software with the same Ubuntu 4.15.0-54 kernel. Specifically, the mini PCs I’ve used are as follows: Intel NUC NUC7CJYSAL (Celeron J4005 Gemini Lake) Pepper JobsGLK-UC2X (Celeron N4100 Gemini Lake) Beelink Gemini X X45 (Celeron J4105 Gemini Lake) Beelink Gemini X X55 (Pentium Silver J5005 Gemini Lake) with updated BIOS Intel NUC NUC7PJYH (Pentium Silver J5005 Gemini Lake) Beelink L55 (i3-5005U Broadwell) On each mini PC, I’ve also run sbc-bench which is […]

Checking Out Machine Check Exception (MCE) Errors in Linux

Machine Check Exception Error Linux

I recently reviewed ODROID-H2 with Ubuntu 19.04, and noticed some errors messages in the kernel log of the Intel Celeron J4105 single board computer while running SBC-Bench benchmark:

I did not know what do make of those errors, but I was told I would get more details with mcelog which can be installed as follows:

There’s just one little problem: it’s not in Ubuntu 19.04 repository, and a bug report mentions mcelog is not deprecated, and remove from Ubuntu 18.04 Bionic onwards. Instead, we’re being told the mcelog package functionality has been replaced by rasdaemon. But before looking into the utilities, let’s find out what Machine Check Exception (MCE) is all about from ArchLinux Wiki: A machine check exception (MCE) is an error generated by the CPU when the CPU detects that a hardware error or failure has occurred. Machine check exceptions (MCEs) can occur for a variety […]

ODROID-H2 Review – Part 2: Ubuntu 19.04

ODROID-H2 Review

After many months of delays due to Intel not mass-producing Gemini Lake processors, Hardkernel started selling ODROID-H2 again, more exactly ODROID-H2 Rev. B, and the end of last month, and the company sent me a full kit for evaluation. You can check out ODROID-H Rev. B with Type 3 case and the assembly instructions in the first part of the review. I’ve now had time to play with the board using the pre-installed Ubuntu 19.04 operating systems so I’ll report my experience in this second part. Note that ODROID-H2 does not rely on a custom version of Ubuntu, and instead you can download and flash Ubuntu 18.04 or 19.04 ISO directly from Ubuntu website. First Boot and System Information I had already connected two SATA drives inside the enclosure, one SSD and one HDD, but before booting the device I connected an HDMI cable, one Ethernet cable, USB keyboard & […]

Testing Ubuntu 18.04 on XIDU PhilPad 2-in-1 Hybrid with Touchscreen

XIDU PhilPad Ubuntu 18.04

So I’ve recently completed the review of XIDU Philpad 2-in-1 hybrid with Windows 10. The laptop features a 13.3″ touchscreen and support stylus, and I was intrigued whether those would work in Ubuntu 18.04. So I flash the Ubuntu 18.04.2 Desktop ISO to a flash drive and installed Ubuntu to another USB flash drive to give it a try with persistent storage. Note that while it’s OK for testing, running Ubuntu 18.04 from a USB flash drive is very slow, so it’s not recommended. The good news is that you can enter the BIOS by pressing either Esc or Del at boot time, an option is available to select Linux in the BIOS. I could then select Partition 1 in my bootable flash drive, and install Ubuntu 18.04 on the other drive with some patience, and everything works smoothly, albeit slowly due to using a cheap USB flash drive during […]

XIDU PhilPad 2-in-1 Hybrid 2K Laptop Review

XIDU PhilPad Review

I had never heard about XIDU laptops and tablets, and it’s apparently the brand name of “Shenzhen Baohuazhong Co Limited” that was founded in 2014 and specializes in the design, development, manufacturing, distributions, and support for computer systems.

Google Fuchsia Operating System Gets its own Developer Website

Fuchsia Documentation

Google has been developing Fuchsia open source operating system based on Zircon kernel for several years. It’s still unclear what’s the end goal. Will it replace Android or/and Chrome OS, ditching the Linux kernel for Zircon in the process? We don’t know, and Google claims its an experimental endeavor. Only the future will tell. We’ve had access to the source code since 2016,  but Google has now launched a dedicated developer website for Fuchsia: fuchsia.dev This is year 2019, and Google being a Western company it should not be surprising the first part of the documentation is a Code of Conduct, but there’s also plenty of technical documentation with a glossary, getting started guide, building instructions, an overview of the OS, code samples, and instructions to contribute either by testing or submitting changes to Gerrit. Fuchsia is strictly a 64-bit operating system at this stage with support for Arm64 and […]
