BIOS/UEFI Leftovers

  • BIOS Update Dell Latitude E6440 on Linux

    My BIOS was 4 years out of date. I thought it was time to update it. I went to the Dell Support page and noticed that they only had *.exe files available. I sighed and was initially frustrated because my initial supposition was that I was going to have to have a working copy of Windows to do the update. My last Dell Latitude, a D630, the BIOS updates required a lot of fiddling on my part. At the time, I would burn a special FreeDOS CD with the BIOS update EXE on it. I figured I would have to do the same with this computer. The good news is, that is not the case and it could be I am the last person to know this bit of information.

    [...]

    Due to my laziness and inhibition to use Windows caused me to avoid pursuing updating my BIOS. Dell, on newer systems (~2015 and later), have built in a service to perform these updates outside of the operating system and has removed or eliminated your excuses for keeping your system up to date and more secure.

    I am glad I took the time today to figure this out and do the proper thing in keeping my system updated.

  • Boothole GRUB2 bug breaks Secure Boot on Linux and Windows
  • Linux GRUB2 bootloader flaw breaks Secure Boot on most computers and servers

    Operating system maintainers, computer manufacturers, security and virtualization software vendors have worked together over the past few months to coordinate a unified response to a vulnerability that allows attackers to bypass boot process integrity verification, one of the key security features of modern computers. The flaw is located in the GRUB2 Linux bootloader, but because of how Secure Boot is implemented, it can be used to compromise the booting process of Windows and other systems as well.

Kernel: Belated Linux 5.8 Coverage and More Linux 5.9 Features

  • Intel Emmitsburg Support Begins Appearing In Linux 5.9

    Not much is publicly known about Intel's Emmitsburg chipset. Prior to noticing some Linux patches recently referencing Intel Emmitsburg, the only other public mentions of it has been in the context of the Windows HWiNFO program mentioning it in their change-log. With Linux 5.9, Intel has begun adding Emmitsburg support. 

    Speculation on Windows sites earlier this year following the HWiNFO mention of "Emmitsburg" pegged it as for Xeon Ice Lake or Cooper Lake. However, that is quite unlikely and is more than likely some other 10nm target. In particular, the Linux kernel already has Cooper Lake and Ice Lake Xeon support in good shape as would be expected given the usage of Linux on servers these days... Intel meanwhile is only adding Emmitsburg to Linux 5.9, thus if their historical punctual open-source support is any indication, the Emmitsburg chipset won't be launched until at least 2021. Linux 5.9 stable will be out in October but won't see widespread support among non-rolling Linux distributions until later on or even in 2021.

  • Linux 5.9 Enables P2PDMA For All AMD CPUs Zen + Newer

    The PCI subsystem updates have been sent in for the Linux 5.9 kernel. Peer-to-peer DMA support is now solid for all AMD CPUs of the Zen family or newer. 

    Support for peer-to-peer DMA (P2PDMA) on AMD Zen and newer CPUs is now set. This is for the whitelist being maintained around this feature. There previously was Zen bits in Linux 5.2 while now for Linux 5.9 appears ironed out.

Linux

Three weeks after the release of the second beta version, the upcoming and highly anticipated MX Linux 19.2 KDE Edition distribution reaches Release Candidate stage and it’s now inches closers to the final release.

The MX Linux development team announced today the availability of the Release Candidate (RC) milestone for public testing. That’s great news because when a project reaches Release Candidate stage it means the final release is very close.

This also means that the team managed to address a lot of the issues from previous beta versions, in an attempt to offer the community a bug-free release of MX Linux 19.2 KDE Edition. One important fix included in this release is to the updater icon right-click menu appearing after an action is completed.

Also: MX-19.2 KDE RC 1 available for testing

  • Several Drivers Promoted Out Of Staging With Linux 5.9

    The "staging" area of the kernel, where new drivers and other code live that has yet to prove itself or live up to kernel code quality standards, saw a few drivers graduate into Linux mainline proper for the current 5.9 cycle.

    Linux 5.9's staging area is quite vibrant along with the IIO (Industrial I/O) changes sent in as part of the pull request as usual by Greg Kroah-Hartman.

  • Linux 5.9 Brings More IBM POWER10 Support, New/Faster SCV System Call ABI

    With Linux 5.8 there is initial support for booting POWER10 CPUs while with Linux 5.9 there is more POWER10 work underway. Additionally, Linux 5.9 is bringing support for the newer and faster system call ABI for POWER9 and newer with the SCV instruction.

    Linux 5.9 has "support for a new faster system call ABI using the scv instruction on Power9 or later." That is the recently covered work on POWER System Call Vectored (SCV). Using SCV can utilize faster registers and reducing machine specific register updates among other benefits for existing POWER9 CPUs and future POWER10 hardware.

  • AMD Sensor Fusion Hub Driver Under Review A Sixth Time For Linux

    While a lot of interesting changes are coming for the in-development Linux 5.9 kernel, sadly a long overdue change isn't going to make the merge window and that is the AMD Sensor Fusion Hub driver.

    The AMD Sensor Fusion Hub is utilized by some AMD Zen laptops for accelerometer and gyroscopic sensors on the devices, akin to the Intel Sensor Hub (ISH) that has long been supported under Linux. While the Sensor Fusion Hub (SFH) is used by laptops going back to Zen 1 hardware, it was only earlier this year that the AMD SFH Linux driver was posted.

  • The people problem

    Systems used to be designed by groups of engineers. Integration and test engineers waited on the developers and toes tended to get trodden on, with hidden code picked apart and untouchable historic designs questioned - all for product development. There was certainly no room for ego! Today, favourite tools may be replaced by those common to the technologies inside a device. Xilinx Zynq devices have two debug ports to allow individual debugging of the Processor Section or Programmable Logic. On Zynq you can chain these ports into one, so tools that are aware of both worlds deliver greater insight. Other devices may only offer specific insight. Vendors will offer a toolset to work with this, but it may be different to what people are used to. Suddenly, this new wonder-device to solve everyone’s design problems is upsetting the engineering apple cart across all engineering disciplines. [...] Silicon vendors offer a step-up in trying to build Linux for their device, and may offer a pre-built image to boot from. This will need modifying for your needs. It’s amazing how many common command-line tools don’t show up by default. Don’t be fooled into thinking moving from a Raspberry Pi to another platform will be straightforward.

  • Python For Loop: Everything You Need to Know

    Loops are one of the essential elements in any programming language, and Python is not an exception to it. Loops are used to repeat a statement or a block of statements multiple times. If there were no concept of loops in programming languages, we have to write each statement again and again for the number of times we want to execute it. Python provides two types of loops to handle looping requirements, i.e., the while loop and the for loop. In this tutorial, we will learn everything about the for loop statement in Python. Before getting started with this tutorial, It is necessary to have Python installed and set up in your environment path. If you don’t have it installed already, refer to our step by step guide to install Python on Linux. The code presented in this tutorial can be run on the python shell, but it is recommended to run the code in a Python IDE. If you don’t have a python IDE installed in your system or want to know which IDE is a better choice to install, you can refer to our guide Top 10 best python IDE compared.

  • rra-c-util 8.3

    n this release of my utility library for my other packages, I finally decided to drop support for platforms without a working snprintf. This dates back to the early 2000s and a very early iteration of this package. At the time, there were still some older versions of UNIX without snprintf at all. More commonly, it was buggy. The most common problem was that it would return -1 if the buffer wasn't large enough rather than returning the necessary size of the buffer. Or, in some cases, it wouldn't support a buffer size of 0 and a NULL buffer to get the necessary size.

Fedora: LTO, Nest and More

  • Fedora 33 Moving Closer To LTO-Optimizing Packages

    Going back to last year Fedora has been working to enable link-time optimizations by default for their packages. That goal wasn't achieved for Fedora 32 but for Fedora 33 this autumn they still have chances of marking that feature off their TODO list.  LTO'ing the Fedora package set can offer not only performance advantages but in some cases smaller binaries as well. This is all about applying the compiler optimizations at link-time on the binary as a whole for yielding often sizable performance benefits and other optimizations not otherwise possible. LTO is great as we often show in benchmarks, especially in the latest GCC and LLVM Clang compilers. 

  • Zamir SUN: Report for session 1 of FZUG @ Nest with Fedora

    Last month, Alick suggested the Fedora Zhongwen User Group (FZUG) can do a online meetup during Nest with Fedora. And based on the survey, people registered for two time slots, the first one is 9:00 PM Saturday evening UTC+8 which is not a good time for Alick, so I take up the coordinating role for this session. As for the tool, we decided to use Jitsi, as it should work fine for most of us and do not have any limitations. What’s more, it’s totally open source. During the meeting, I firstly introduced Nest with Fedora and it’s previous offline version, Flock to Fedora, to the attendees. It’s interesting to see that during the past years, we not only have new users in China, but also new contributors. One attendee shares that his motivation of being a packager is that deploying packages for their research in the lab is cumbersome before. So he decided to package all into Fedora and then he can just simply install them on every machine. It is good to know that people contribute back because they want to solve their own problems. Maybe this can be a talking point to attract more contributors in the future. After the self introduction, we continue by sharing our interesting stores with Linux. That is a lot of fun.

  • Jon Chiappetta: Last piece of relay software needed for my home bridged network

    If you are running a bridged/relayd network with macs on it you may need to also forward the multicast broadcasts (mDNS related) that allow the devices to automatically discover each other. On the WRT wifi client side, there is a pkg called avahi-daemon and you can configure to operate in “reflector” mode to forward these broadcasts across the specified interfaces. Running this service along with the dhcprb C program which takes care of layer 2 arp requests & dhcp gateway forwarding has been pretty smooth so far!
