  • AMD Releases BIOS Fix To Motherboard Partners For Booting Newer Linux Distributions

    AMD has just alerted us that they have released a BIOS fix to their motherboard partners that takes care of the issue around booting newer Linux distributions on the new Zen 2 processors.

    Earlier this week I mentioned AMD would be working on a BIOS fix to address the fundamental problem with booting newer systemd-using Linux distributions on their new Ryzen 3000 series processors. However, I hadn't expected the fix to make it to motherboard vendors in less than one week!

  • AMD: Patch On The Way For Ryzen 3000 Customers Affected By 'Destiny 2' And Linux Boot Problems

    AMD says it was able to root cause and resolve both issues fairly quickly in its BIOS code with a patch, and the company expects motherboard vendors to distribute the patch (potentially in beta BIOS form) by next week.

    Earlier this week a growing number of complaints amassed from Windows gamers concerning the inability to launch Activision's Destiny 2 with various Ryzen 3000 CPUs. On the Linux side of the fence, a fairly critical bug emerged that straight up prevented a system from booting with 5.0 or newer Linux kernels.

    It's nice to have these both addressed and resolved within the first week of launch, and hopefully the motherboard vendors will act quickly to seed this patch to their users. Keep an eye on those BIOS updates!

AMD Linux Problems

  • AMD Ryzen 3000 systems need a BIOS fix for Linux, 'Destiny 2' issues

    Last week AMD officially released its new Ryzen 3000 Series CPUs and Radeon RX 5700 graphics cards, but there's a small problem with the CPUs.

  • AMD Ryzen 3000 causes boot problems for some newer Linux distros

    Just last week AMD launched its latest Ryzen 3000 series of CPUs. The third-generation Ryzen chips are the first to be based on 7nm technology, but there is a problem for users of some Linux-based systems.

    For distributions based on newer versions of the Linux kernel, an issue renders systems unable to boot. Some users have managed to patch the systemd component with an older version to allow successful booting, but a BIOS update from AMD is what's needed.

New articles about AMD tackling Linux issues

  • AMD Ryzen 3000 Systems To Get BIOS Update To Fix Linux And Destiny 2 Issues

    Linux users did find a workaround by either taking the systemd component to an older version or running a newer patched edition. Windows gamers complained that Destiney 2 wouldn’t launch on systems with AMD Ryzen 3000 Series CPUs.
    AMD has confirmed to Phoronix in a statement hat a BIOS fix has been implemented for the cause of these issues and that it has been distributed to motherboard manufacturers. “AMD has identified the root cause and implemented a BIOS fix for an issue impacting the ability to run certain Linux distributions and Destiny 2 on Ryzen 3000 processors,” it said.

  • AMD Ryzen 3000 causes boot problems for a few Linux Distros, and issues with Destiny 2

    Some users did manage to get around this glitch either by taking the systemd component back to an old version or a newer patched edition. However, now there are complaints being raised by gamers on Windows since they are having issues with Destiny 2 on the new CPUs. As reported to Bungie, over the last couple of days, some users complained that the game refuses to launch when used on PCs with the new chips.

Late Coverage of Confidential Computing Consortium

  • Microsoft Partners With Google, Intel, And Others To Form Data Protection Consortium

    The software maker joined Google Cloud, Intel, IBM, Alibaba, Arm, Baidu, Red Hat, Swisscom, and Tencent to establish the Confidential Computing Consortium, a group committed to providing better private data protection, promoting the use of confidential computing, and advancing open source standards among members of the technology community.

  • #OSSUMMIT: Confidential Computing Consortium Takes Shape to Enable Secure Collaboration

    At the Open Source Summit in San Diego, California on August 21, the Linux Foundation announced the formation of the Confidential Computing Consortium. Confidential computing is an approach using encrypted data that enables organizations to share and collaborate, while still maintaining privacy. Among the initial backers of the effort are Alibaba, Arm, Baidu, Google Cloud, IBM, Intel, Microsoft, Red Hat, Swisscom and Tencent. “The context of confidential computing is that we can actually use the data encrypted while programs are working on it,” John Gossman, distinguished engineer at Microsoft, said during a keynote presentation announcing the new effort. Initially there are three projects that are part of the Confidential Computing Consortium, with an expectation that more will be added over time. Microsoft has contributed its Open Enclave SDK, Red Hat is contributing the Enarx project for Trusted Execution Environments and Intel is contributing its Software Guard Extensions (SGX) software development kit. Lorie Wigle, general manager, platform security product management at Intel, explained that Intel has had a capability built into some of its processors called software guard which essentially provides a hardware-based capability for protecting an area of memory.

Graphics: Mesa Radeon Vulkan Driver and SPIR-V Support For OpenGL 4.6

  • Mesa Radeon Vulkan Driver Sees ~30% Performance Boost For APUs

    Mesa's RADV Radeon Vulkan driver just saw a big performance optimization land to benefit APUs like Raven Ridge and Picasso, simply systems with no dedicated video memory. The change by Feral's Alex Smith puts the uncached GTT type at a higher index than the visible vRAM type for these configurations without dedicated vRAM, namely APUs.

  • Intel Iris Gallium3D Is Close With SPIR-V Support For OpenGL 4.6

    This week saw OpenGL 4.6 support finally merged for Intel's i965 Mesa driver and will be part of the upcoming Mesa 19.2 release. Not landed yet but coming soon is the newer Intel "Iris" Gallium3D driver also seeing OpenGL 4.6 support. Iris Gallium3D has been at OpenGL 4.5 support and is quite near as well with its OpenGL 4.6 support thanks to the shared NIR support and more with the rest of the Intel open-source graphics stack. Though it's looking less likely that OpenGL 4.6 support would be back-ported to Mesa 19.2 for Iris, but we'll see.
