Kernel and Graphics: exFAT, Linux 5.12, Mesa's Panfrost Gallium3D and Mesa 21.0

• Linux's exFAT Driver Will Soon Be Able To Delete Big Files Much Faster - Phoronix

  For those making use of Linux's modern exFAT file-system, a significant optimization is on the way for when deleting files with the "dirsync" mount option set.  The exFAT file-system driver for Linux 5.12 should be able to delete (large) files much faster when running with the "dirsync" mount option set where the directory updates are done synchronously. 

 

• AMD + Older Intel CPUs To See Much Faster AES-NI XTS Crypto Performance On Linux 5.12 - Phoronix

  AMD processors along with older Intel processors will enjoy much faster AES-NI XTS crypto performance with the Linux 5.12 kernel this spring.  Processors supporting AES-NI instructions and that also are subject to Retpolines as part of their Spectre V2 mitigations will enjoy a big speed-up with AES-NI XTS for that next version of the Linux kernel. This includes past and current AMD processors as well as older Intel CPUs, but recent Intel processors do not need the return trampolines and thus not subject to this speed-up as they are not currently handicapped. 

• Mesa's Lima Driver Finally Implements OpenGL Shader Cache Support - Phoronix

  While Mesa's Panfrost Gallium3D driver has been working out well for modern ARM Mali open-source graphics support, for the old Mali 400/450 series hardware there still is the "Lima" driver within Mesa that doesn't receive too much attention these days (just around 70 commits over the past year) but as its first work of 2021 saw an initial shader cache implementation.

• Radeon Vulkan "RADV" Driver Saw Many Optimizations This Week For Mesa 21.0 - Phoronix

  Prior to Mesa 21.0 being branched this week in preparations for the quarterly stable Mesa3D release, a number of open-source Radeon Vulkan "RADV" driver optimizations were merged.

Audiocasts/Shows: TWIL and GNU World Order

• TWIL 134: WINE 6.0, Flatpak 1.10, Fedora Kinoite, Slimbook Titan, AlmaLinux, JingOS

  On this episode of This Week in Linux, we’ve got an update for you about a CentOS alternative from CloudLinux called AlmaLinux. The company Slimbook announced a new Laptop called the Slimbook Titan and it is a very interesting piece of hardware with AMD Ryzen 7 & RTX 3070. We’ve also got releases from some big open source projects like WINE 6.0 and Flatpak 1.10. We’ve also got some interesting distro news from Fedora and a new OS called JingOS which has a very iPad-like design. In App News, we’ll talk about Mozilla’s VPN Now Available for Linux and we’ll end the show with a big Humble Bundle Bonanza. All that and much more on Your Weekly Source for Linux GNews!
