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

Graphics/Benchmarks
  • 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.

New WireGuard Snapshot Offers Better Compatibility With Distributions/Kernels

WireGuard sadly isn't slated for the now-open Linux 5.4 merge window, but lead developer Jason Donenfeld has put out a new development snapshot of this open-source secure VPN tunnel. Coming barely two weeks since the previous WireGuard snapshot, this newest development release isn't too heavy on the changes but the focus is on better portability/compatibility. Read more

A Simple Review of GNOME 3.34

That's all for now. As always, I love how simple and beautiful GNOME release announcement was. After testing in 3 days, I immediately like this version more than the previous one for the speed improvement and I hope Ubuntu and other distros adopt it soon. Ah, I forgot, regarding Ubuntu, good news for us: next October's Ubuntu Eoan Ermine will feature 3.34! Regarding GNOME, I don't know if this is coincidence or what, but this year's KDE Plasma is faster and smoother and so is GNOME. I think next GNOME 3.36 will be faster and better as well. Finally I would love to say thank you GNOME developers! You all did well in last 6 month. How do you think about 3.34? Let me know in the comment section!

PulseAudio 13 Released with Dolby TrueHD and DTS-HD Master Audio Support, More

Released three months after the PulseAudio 12 series, PulseAudio 13 is here with support for Dolby TrueHD and DTS-HD Master Audio, support for the SteelSeries Arctis 5 USB headset, improved initial card profile selection for ALSA cards, as well as S/PDIF improvements for CMEDIA USB2.0 High-Speed True HD Audio. The PulseAudio 13 series also adds several new module arguments, including "max_latency_msec" for module-loopback, "stream_name" for module-rtp-send, and "avoid_resampling" for module-udev-detect and module-alsa-card, and no longer uses persistent Bluetooth card profile choices by default, recommending users to use A2DP by default.

GNOME Firmware App Launches Officially to Make Updating Firmware Easier on Linux

Promising to make firmware updates easier to deploy, GNOME Firmware is a graphical application for power users that lets them check for new firmware for their devices, update or downgrade current firmware, as well as to install new firmware. GNOME Firmware is designed as an optional utility for GNOME users, as well as users of other desktop environments. "GNOME Firmware is designed to be a not-installed-by-default power-user tool to investigate, upgrade, downgrade and re install firmware," said Richard Hughes in a blog post. "GNOME Software will continue to be used for updates as before. Vendor helpdesks can ask users to install GNOME Firmware rather than getting them to look at command line output." Read more
