  • AMD Secure Memory Encryption Has a Flaw, Now Disabled by Default in Linux Kernel

    According to a report from Phoronix, the Linux 5.15 kernel is receiving a new fix that involves disabling AMD's Secure Memory Encryption, or SME. This feature is normally enabled by default, but due to unexpected boot failures on some AMD machines, SME will now be disabled by default. Devs will update the Linux 5.15 kernel first, but the change will also move to prior kernels.

    AMD Secure Memory Encryption is a feature exposed to AMD's EPYC and Ryzen Pro processors that allows the CPUs to encrypt the memory at a hardware level. AMD says the feature offers no significant impact on system performance and works with any OS and application because it's hardware-accelerated and doesn't rely upon software.

  • [Older] Linux Kernel Concurrency Cheat Sheet

    Navigating Linux kernel APIs can be very time-consuming, so Linux ksplice guru Vegard Nossum put together a very handy time-saving cheat sheet to help traversing Linux kernel concurrency primitives.

    As a child, I spent countless hours playing games on my Nintendo Game Boy. As I grew older and started programming in QBasic on MS-DOS, I also got curious about how Game Boy games worked.

  • Habana Labs For Linux 5.16 To Bring Peer-To-Peer Support With DMA-BUF - Phoronix

    The drama around DMA-BUF code for the Habana Labs AI driver appears to be wrapping up with the Linux 5.16 cycle that is coming up.

    The Habana Labs driver changes were mailed out today for queuing in char/misc ahead of next month's Linux 5.16 merge window. This driver for supporting the AI inference and training accelerators at the Intel-owned company has some exciting updates for this next kernel release.

  • mesa recompiled with gallium drivers

    The guys have been reporting slow Nvidia performance, for example a report from forum member Keef here:

    https://forum.puppylinux.com/viewtopic.php?p=39261#p39261

    I had compiled all of the packages in OpenEmbedded without libllvm, as it is a hug library, about 60MB. However, it meant had to leave out some drivers in the 'mesa' package.

  • Mesa 22.0 Lands Some Patches Toward OpenCL Image Support - Phoronix

    Mesa 22.0-devel is one step closer to having OpenCL image support that is sought after by many individuals for allowing more OpenCL-enabled desktop software to work nicely with this open-source OpenCL component in Mesa.

    For nearly a year there has been the work-in-progress merge request implementing OpenCL 1.2 image support. That work was started by Red Hat's Karol Herbst.

Open source mind mapping with Draw.io

There's something special about maps. I remember opening the front book cover of JRR Tolkien's The Hobbit when I was younger, staring at the hand-drawn map of Middle Earth, and feeling the wealth of possibility contained in the simple drawing. Aside from their obvious purpose of actually describing where things are in relation to other things, I think maps do a great job of expressing potential. You could step outside and take the road this way or that way, and if you do, just think of all the new and exciting things you'll be able to see. Read more
