  • AMD Linux EDAC Driver Prepares For Zen 4, RDDR5 / LRDDR5 Memory - Phoronix

    AMD's Linux engineers continue preparing for next-gen EPYC server processors based on Zen 4 and supporting DDR5 memory.

    In addition to recent work like preparing for up to 12 CCDs per socket, temperature monitoring, and other bits, out today is a set of patches for AMD's EDAC (Error Detection and Correction) driver code for the next-generation Zen 4 server processors.

    The work sent out today includes adding support for RDDR5 and LRDDR5 memory support to the driver (conventional DDR5 support was already mainlined). This is for Registered DDR5 memory support as well as Load-Reduced DDR5 memory support. LRDDR5 support is for the higher memory density servers, similar to LRDIMMs with prior DDR generations.

  • RADV Working On ETC2 Emulation Support For Newer Radeon GPUs To Satisfy Android - Phoronix

    Mesa's Radeon Vulkan driver "RADV" is implementing emulated support for ETC2 texture compression to use with newer AMD GPUs to improve compatibility with Google's Android operating system.

    ETC2 is the royalty-free texture compression standard developed by Ericsson that has worked its way into the OpenGL and OpenGL ES specifications. RADV already supports ETC2 with Radeon GPUs having the support, but that is rather limited to the likes of AMD Stoney APUs and Vega/GFX9 graphics processors. Unfortunately, the ETC2 support on the AMD GPU side has been rather spotty and not supported by newer APUs/GPUs.

  • XWayland gets DRM leasing support for helping VR on Linux

    A big improvement has been merged into XWayland called DRM (Direct Rendering Manager) Leasing, which should allow good VR support under Wayland. Something we've been waiting on!

  • Steinar H. Gunderson - Speeding up Samba AD

    One Weird Trick(TM) for speeding up a slow Samba Active Directory domain controller is seemingly to leave and rejoin the domain. (If you don't have another domain controller, you'll need to join one in temporarily.) Seemingly, not only can you switch to LMDB (which has two fsyncs instead of eight on commit—which matters a lot, especially on non-SSDs, as the Kerberos authentication path has a blocking write to update account statistics), but you also get to regenerate the database, giving you the advantage of any new indexes since last upgrade.

  • How to Change File Extensions on Linux

    File extensions help both operating systems and users distinguish between different file formats and understand the contents stored inside them. When you see a file with the ".txt" extension, you instantly know it contains text data. Similarly, ".exe" file is a Windows executable and ".sh" files are Linux shell scripts. But what if you want to change these extensions for some reason? Perhaps you need to rename a text file to a Bash script. Simply writing the code in a text file won't do the job. On Linux, changing file extensions is much easier than you might think.
