Ubuntu 17.10 Temporarily Pulled Due To A BIOS Corrupting Problem (phoronix.com) 167

An anonymous reader writes: Canonical has temporarily pulled the download links for Ubuntu 17.10 "Artful Aardvark" from the Ubuntu website due to ongoing reports of some laptops finding their BIOS corrupted after installing this latest Ubuntu release. The issue is appearing most frequently with Lenovo laptops but there are also reports of issues with other laptop vendors as well. This issue appears to stem from the Intel SPI driver in the 17.10's Linux 4.13 kernel corrupting the BIOS for a select number of laptop motherboards. Canonical is aware of this issue and is planning to disable the Intel SPI drivers in their kernel builds. Canonical's hardware enablement team has already verified this works around the problem, but doesn't provide any benefit if your BIOS is already corrupted.

AMD Is Open-Sourcing Their Official Vulkan Linux Driver (phoronix.com) 75

An anonymous reader writes: While many of you have likely heard of the "RADV" open-source Vulkan driver, it's been a community-written driver up to this point in the absence of AMD's official, cross-platform Vulkan driver being open-source. That's now changed with AMD now open-sourcing their official Vulkan driver. The code drop is imminent and they are encouraging the use of it for quick support of new AMD hardware, access to the Radeon GPU Profiler, easy integration of AMD Vulkan extensions, and enabling third-party extensions. For now at least it does provide better Vulkan performance than RADV but the RADV developers have indicated they plan to continue development of their Mesa-based Vulkan driver.

Clear Linux Beats CentOS, openSUSE, and Ubuntu in (Enterprise) Benchmark Tests (phoronix.com) 136

An anonymous reader writes: Recently completed Linux distro benchmarks by Phoronix show Intel's Clear Linux is the most powerful on x86 hardware. A six-way, enterprise-focused Linux distro comparison show Clear Linux being the fastest with a Core i9 and Xeon systems, easily beating CentOS, openSUSE, and Ubuntu in a majority of the tests.

When doing an 11-way Linux distro boot test they also found Clear Linux easily booted the fastest followed by the Clear-inspired Solus distribution. Clear Linux does work on AMD hardware and works on Intel CPUs back to Sandy Bridge but leverages its speed from optimized compiler settings, specially built libraries capable of AVX instructions on supported systems, a specially tuned kernel configuration, and other optimizations/patches.

Debian 9.2 and Fedora 27 "ended up being dropped from this article due to data overload," the article concludes, "and those distributions really not offering anything really different in terms of the performance."

Intel Planning To End Legacy BIOS Support By 2020, Report Says (phoronix.com) 122

Michael Larabel, writing for Phoronix: Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher. Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems. By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+. Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.

Oracle Engineer Talks of ZFS File System Possibly Still Being Upstreamed On Linux (phoronix.com) 131

New submitter fstack writes: Senior software architect Mark Maybee who has been working at Oracle/Sun since '98 says maybe we "could" still see ZFS be a first-class upstream Linux file-system. He spoke at the annual OpenZFS Developer Summit about how Oracle's focus has shifted to the cloud and how they have reduced investment in Solaris. He admits that Linux rules the cloud. Among the Oracle engineer's hopes is that ZFS needs to become a "first class citizen in Linux," and to do so Oracle should port their ZFS code to Oracle Linux and then upstream the file-system to the Linux kernel, which would involve relicensing the ZFS code.

Linux LTS Kernels To Now Be Maintained For Six Years (phoronix.com) 79

An anonymous reader writes: In a bid to help Android smartphone vendors the Linux LTS (Long Term Support) kernels will now be maintained for a period of six years. The Linux LTS initiative backed by the Linux Foundation has supported annual LTS kernels for two years worth of updates, but that is being changed for Linux 4.4+ at the request of Google and their Project Treble. This means the Linux 4.4 LTS kernel will be maintained through 2022 and the upcoming Linux 4.14 LTS through 2023 for security/bug fixes in order to last a complete "device lifecycle."

AMD Opteron Vs EPYC: How AMD Server Performance Evolved Over 10 Years (phoronix.com) 34

New submitter fstack writes: Phoronix has carried out tests comparing AMD's high-end EPYC 7601 CPU to AMD Opteron CPUs from about ten years ago, looking at the EPYC/Opteron Linux performance and power efficiency. Both on the raw performance and performance-per-Watt, the numbers are quite staggering though the single-threaded performance hasn't evolved quite as much. The EPYC 7601 is a $4,200 USD processor with 32 cores / 64 threads. The first of many tests was with NAS Parallel Benchmarks: "For a heavily threaded test like this, going from a single Opteron 2300 series to the EPYC 7601 yielded around a 40x increase in performance," reports Phoronix. "Not bad when also considering it was only a 16x increase in the thread count (4 physical cores to 32 cores / 64 threads). The EPYC 7601 has a lower base clock frequency than the Opteron 2300 CPUs tested but has a turbo/boost frequency higher, among many architectural advantages over these K10 Opterons. With the NASA test's Lower-Upper Gauss-Seidel solver, going from the dual Opteron 2384 processors to a single EPYC 7601 yields around a 25x improvement in performance over the past decade of AMD server CPUs. Or in looking at the performance-per-Watt with the LU.C test, it's also around a 25x improvement over these older Opterons."

New Ryzen Running Stable On Linux, Threadripper Builds Kernel In 36 Seconds (phoronix.com) 186

An anonymous reader writes: After AMD confirmed the a "performance marginality problem" affecting some Ryzen Linux users, RMAs are being issued and replacement Ryzen processors arriving for affected opensource fans. Phoronix has been able to confirm that the new Ryzen CPUs are running stable without the segmentation fault problem that would occur under very heavy workloads. They have also been able to test now the Ryzen Threadripper 1950X. The Threadripper 1950X on Linux is unaffected by any issues unless you count the lack of a thermal reporting driver. With the 32 threads under Linux they have been able to build the Linux kernel in just about a half minute.

How Open Source Advocates Celebrated The 26th Anniversary of Linux (linux.com) 99

To celebrate Linux's 26th anniversary, the Linux Foundation tweeted a picture of Tux on a birthday cake, and linked to an essay on OpenSource.com by FreeDOS founder Jim Hall: My first Linux distribution was Softlanding Linux System (SLS) 1.03, with Linux kernel 0.99 alpha patch level 11. That required a whopping 2MB of RAM, or 4MB if you wanted to compile programs, and 8MB to run X windows... To celebrate, I reinstalled SLS 1.05 to remind myself what the Linux 1.0 kernel was like and to recognize how far Linux has come since the 1990s.
"Getting X windows to perform was not exactly easy..." Hall writes, adding "the concept of a desktop didn't exist yet." Meanwhile Phoronix celebrated by republishing that fateful email Linus Torvalds sent on August 25, 1991. And Fossbytes shared the most recent statistics about modern-day Linux's 20 million lines of code from the Linux Foundation: During the period between the 3.19 and 4.7 releases, the kernel community was merging changes at an average rate of 7.8 patches per hour; that is a slight increase from the 7.71 patches per hour seen in the previous version of this report, and a continuation of the longterm trend toward higher patch volumes.

AMD Confirms Linux 'Performance Marginality Problem' On Ryzen (phoronix.com) 120

An anonymous reader writes: Ryzen customers experiencing segmentation faults under Linux when firing off many compilation processes have now had their problem officially acknowledged by AMD. The company describes it as a "performance marginality problem" affecting some Ryzen customers and only on Linux. AMD confirmed Threadripper and Epyc processors are unaffected; they will be dealing with the issue on a customer-by-customer basis, and their future consumer products will see better Linux testing/validation. Ryzen customers believed to be affected by the problem can contact AMD Customer Care. Michael Larabel writes via Phoronix: "With the Ryzen segmentation faults on Linux they are found to occur with many, parallel compilation workloads in particular -- certainly not the workloads most Linux users will be firing off on a frequent basis unless intentionally running scripts like ryzen-test/kill-ryzen. As I've previously written, my Ryzen Linux boxes have been working out great except in cases of intentional torture testing with these heavy parallel compilation tasks. [AMD's] analysis has also found that these Ryzen segmentation faults aren't isolated to a particular motherboard vendor or the like, contrary to rumors/noise online due to the complexity of the problem."

It Will Take Fedora More Releases To Switch Off Python 2 (phoronix.com) 94

An anonymous reader quotes Phoronix: Finalizing Fedora's switch from Python 2 to Python 3 by default is still going to take several more Fedora release cycles and should be done by the 2020 date when Python 2 will be killed off upstream. While much of Fedora's Python code is now compatible with Py3, the /usr/bin/python still points to Python 2, various python-* packages still mean Python 2... The end game is to eventually get rid of Python 2 from Fedora but that is even further out.
Fedora is now gathering feedback on a Wiki page explaining the switch.

Slackware, Oldest Linux Distro Still In Active Development, Turns 24 70

sombragris writes: July 17 marked the 24th anniversary of Slackware Linux, the oldest GNU/Linux still in active development, being created in 1993 by Patrick Volkerding, who still serves as its BDFL. Version 14.2 was launched last year, and the development version (Slackware-current) currently offers kernel 4.9.38, gcc 7.1, glibc 2.25, mesa 17.1.5, and KDE and Xfce as official desktops, with many others available as 3rd party packages. Slackware is also among the Linux distributions which have not adopted systemd as its init system; instead, it uses a modified BSD init which is quite simple and effective. Slackware is known to be a solid, stable and fast setup, with easy defaults which is appreciated by many Linux users worldwide. Phoronix has a small writeup noting the anniversary and there's also a nice reddit thread.

Survey Finds Most Popular Linux Laptop Distros: Ubuntu and Arch (phoronix.com) 141

After collating 30,171 responses, Phoronixhas released some results from their first Linux Laptop Survey. An anonymous reader quotes their report: To little surprise, Ubuntu was the most popular Linux distribution running on the respondents' laptops. 38.9% of the respondents were said to be using Ubuntu while interesting in second place was Arch Linux at 27.1% followed by Debian at 15.3%. Rounding out the top ten were then Fedora at 14.8%, Linux Mint in 5th at 10.8%, openSUSE/SUSE in sixth at 4.2%, Gentoo in seventh at 3.9%, CentOS/RHEL in eighth at 3.1%, Solus in ninth at 2%, and Manjaro in tenth at 1.6%. The other Linux distributions had each commanded less than 1% of the overall response.
Only 10.3% of respondents said their most recent laptop purchase came pre-loaded with Linux. But 29.3% are now dual-booting their Linux laptop with Windows, while another 4.4% were dual-booting with yet another Linux distribution.

Phoronix Announces '2017 Linux Laptop Survey' (google.com) 66

Phoronix is hosting a 2017 Linux Laptop Survey. From their site: While Linux laptop compatibility is much better than where it was years ago, it's still not too uncommon to run into display/hybrid issues, shorter battery life under Linux than Windows or macOS, touchpad problems, and other occasional compatibility/performance shortcomings. So we've established this Linux Laptop Survey in conjunction with Linux stakeholders to hopefully gather more feedback that will be useful to many different parties...
The survey will be online until July 6th, after which the results will be publicly available, and will determine the most popular brands, distros, screen sizes, and GPUs, as well as common pain points and popular price points. And one particularly interestng question asks respondents what they'd like to see in a "dream Linux laptop."

Richard Stallman Acknowledges Libreboot Is No Longer A Part of GNU (gnu.org) 397

Libreboot became an official GNU project in May. Now an anonymous Slashdot reader writes: Richard Stallman has officially announced that Libreboot is no longer a GNU package. The maintainer of Libreboot had tried to leave the GNU project in September 2016, but the departure was not acknowledged until January 2017. Libreboot is a replacement for proprietary BIOS systems, effectively a distribution of coreboot without any binary blobs and adding an automated build/install process.
In the post titled "Goodbye to GNU Libreboot," Stallman wrote that "When a package's maintainer steps down, that doesn't by itself break the relationship between GNU and the package. If it is left without a maintainer but is still useful, the GNU Project will usually look for new maintainers to work on it. However, we can instead drop ties with the package, if that seems the right thing to do.

"A few months ago, the maintainer of GNU Libreboot decided not to work on Libreboot for the GNU Project any more. That was her decision to make. She also asserted that Libreboot was no longer a GNU package -- something she could not unilaterally do. The GNU Project had to decide what to do in regard to Libreboot. We have decided to go along with the former GNU maintainer's wishes in this case, for a combination of reasons: (1) it had not been a GNU package for very long, (2) she was the developer who had originally made it a GNU package, and (3) there were no major developers who wanted to continue developing Libreboot under GNU auspices."

Linus Torvalds Officially Announces the Release of Linux Kernel 4.8 (softpedia.com) 95

Slashdot reader prisoninmate brings news from Softpedia: Today, Linus Torvalds proudly announced the release and availability for download of the Linux 4.8 kernel branch, which is now the latest stable and most advanced one. Linux kernel 4.8 has been in development for the past two months, during which it received no less than eight Release Candidate testing versions that early adopters were able to compile and install on their GNU/Linux operating system to test various hardware components or simply report bugs...

A lot of things have been fixed since last week's RC8 milestone, among which we can mention lots of updated drivers, in particular for GPU, networking, and Non-Volatile Dual In-line Memory Module (NVDIMM), a bunch of improvements to the ARM, MIPS, SPARC, and x86 hardware architectures, updates to the networking stack, as well as to a few filesystem, and some minor changes to cgroup and vm.

The kernel now supports the Raspberry Pi 3 SoC as well as the Microsoft Surface 3 touchscreen.
