  • Btrfs on CentOS: Living with Loopback | Linux Journal

    The btrfs filesystem has taunted the Linux community for years, offering a stunning array of features and capability, but never earning universal acclaim. Btrfs is perhaps more deserving of patience, as its promised capabilities dwarf all peers, earning it vocal proponents with great influence. Still, none can argue that btrfs is unfinished, many features are very new, and stability concerns remain for common functions. Most of the intended goals of btrfs have been met. However, Red Hat famously cut continued btrfs support from their 7.4 release, and has allowed the code to stagnate in their backported kernel since that time. The Fedora project announced their intention to adopt btrfs as the default filesystem for variants of their distribution, in a seeming juxtaposition. SUSE has maintained btrfs support for their own distribution and the greater community for many years. For users, the most desirable features of btrfs are transparent compression and snapshots; these features are stable, and relatively easy to add as a veneer to stock CentOS (and its peers). Administrators are further compelled by adjustable checksums, scrubs, and the ability to enlarge as well as (surprisingly) shrink filesystem images, while some advanced btrfs topics (i.e. deduplication, RAID, ext4 conversion) aren't really germane for minimal loopback usage. The systemd init package also has dependencies upon btrfs, among them machinectl and systemd-nspawn. Despite these features, there are many usage patterns that are not directly appropriate for use with btrfs. It is hostile to most databases and many other programs with incompatible I/O, and should be approached with some care.

    Intel's Kenneth Graunke has written a few patches for Intel Gen12+ graphics chips that boost graphics performance by one to twelve percent. Don't get too excited, it only applies to Intel Tigerlake and newer and they won't arrive in mainstream GNU/Linux distributions until Mesa 20.3 is released mid-December.

  • The Vulkan driver for Raspberry Pi 4 becomes official for Linux, merged into Mesa | GamingOnLinux

    In case you've missed what's been going on, the progress on proper Vulkan support for the Raspberry Pi 4 has been going really well. So well in fact, that it's been merged into the upstream Mesa project and so it's all a bit more official. Writing in a guest post on the official Raspberry Pi blog, Igalia's Iago Toral, who has been largely responsible for hacking away on the v3dv driver gave an update on the progress. [...] Plenty more still to be done, and as they said, passing tests is one thing but real-world use is another. I've no doubt people will find many ways to break it while it's still in development. That's part of the point of being official in Mesa now though, makes it vastly easy to try it. As a proud owner of a Raspberry Pi 4, it's going to be fun to see it in action with Vulkan now.

  • AMDVLK 2020.Q4.1 Is Released With A New Vulkan Extension And Three Game-Specific Fixes - LinuxReviews

    AMD has released a new version of their AMDVLK Vulkan driver for Linux with support for one new Vulkan extensions and game-specific fixes for Wolfenstein II: The New Colossus, Second Extinction and X-plane. Performance is still overall worse than the AMD RAVD Vulkan driver that comes with Mesa 20.2.0 and performance is much worse in specific graphics benchmarks and image up-scaling. [...] AMDVLK's performance has long been sub-par compared to Mesa's RADV driver. That's the driver GNU/Linux distributions ship with, AMDVLK is optional. AMDVLK is much closer to the Windows-driver than Mesa's RADV and compatibility may be a reason to install the latest and greatest AMDVLK 2020.Q4.1 driver. Performance is, as you will see if you read on, not a reason to install it.

  • AMDVLK 2020.Q4.1 Released With Various Game Fixes - Phoronix

    AMD has issued their first open-source Vulkan driver code drop of the quarter with AMDVLK 2020.Q4.1. The main changes of AMDVLK 2020.Q4.1 are updating against the Vulkan API 1.2.156 revision and enabling support for VK_EXT_shader_image_atomic_int64. VK_EXT_shader_image_atomic_int64 allows for 64-bit integer atomic operations to work on images.
