Radeon Linux Drivers Now Only Officially Support Smart Access Memory On Zen 3 + RDNA2

While many Linux users were excited when finding out the open-source AMD Radeon Linux drivers were allowing Smart Access Memory (Resizable BAR) support on older motherboards/CPUs and older Radeon GPUs rather than basically the very latest AMD products as seen on Windows, there is a change of course due to bugs. Now, officially, Mesa 21.0 is just enabling Smart Access Memory for systems with AMD Zen 3 processors and RDNA 2 graphics cards though if you have other hardware you can force-enable it.

Lutris 0.5.8.2 Linux Game Manager Brings Wayland Improvements, Other Additions

Lutris as the open-source Linux game manager that makes it easy to install Wine game as well as various emulator games, Steam titles, and more, is out with an interesting update to kick off the new year.

The new Lutris 0.5.8.2 release brings multiple Wayland fixes like pop-over menus not working and the game bar being unselected. There are also other interesting additions like support for automatically downloading DXVK when Lutris is starting, FSYNC2 feature detection, initial support for Adobe Air games

PicoXcell Support Finally Slated For Removal From The Linux Kernel

PicoXcell, the ARM SoCs from PicoChip more than a decade ago before being bought out by MindSpeed and then Intel, are set to finally see their Linux support removed this year.

PicoXcell was focused on HSPA (High Speed Packet Access) handling back during the mobile 3G days. But with no new hardware in close to a decade and Intel not working on any Linux kernel support improvements for PicoXcell given its obsolete state with what is supported by the mainline kernel, the Linux support is slated for removal.

Fedora 34 Planning To Offer LXQt 0.16 Desktop Packages

Keeping up with Fedora's tradition of offering the very latest open-source software packages, the straight-forward proposal was made this week to update its lightweight LXQt desktop packages against the new LXQt 0.16.

Back in November marked the release of LXQt 0.16 that was comprised mostly of bug fixes but did bring some configuration improvements, power management handling work, support for extracting RPMs, new themes, and other mostly small changes.

A proposal has been filed to update the existing LXQt packages in

Intel Submits Initial Batch Of Graphics Driver Updates Slated For Linux 5.12

Now that more developers are returning from their holiday breaks, the first pull request to DRM-Next has been submitted of Intel kernel graphics driver material destined for Linux 5.12 .

Sent in today were the first of several batches of new Intel "i915" kernel graphics driver feature updates to DRM-Next in queuing ahead of the Linux 5.12 merge window. Among the code submitted today include:

- Frame-buffer Compression (FBC) fixes for Gen12 Tiger Lake graphics.

Radeon FreeSync Video Mode Optimization Updated For The AMDGPU Linux Driver

Last month we wrote about AMD engineers working on an experimental video mode optimization for FreeSync with the open-source AMDGPU Linux kernel driver. With AMD staff getting back to work following the holidays, an updated patch set was submitted today.

The AMDGPU FreeSync video optimization was updated today and looks like there is enough interest and punctual updates that it's possible we could see it mainlined for say Linux 5.12, but it didn't make it in time for the current 5.11 cycle. This

The Qt Company Is Tomorrow Moving Qt 5.15 To Its Commercial-Only LTS Phase

As part of their fundamental shift to restrict Qt LTS point releases to commercial customers , The Qt Company is closing the Qt 5.15 branch to the public tomorrow with future Qt 5.15 LTS point releases to be restricted to paying licensees.

The notice was sent out today that beginning tomorrow (5 January) will start the commercial-only LTS phase of Qt 5.15. The existing Qt 5.15 branches will be publicly visible but will not see any new patches. The public branches

AMD Performance On Linux 5.11 Remains Mixed Due To Schedutil With Frequency Invariance

Back on Christmas I wrote about Linux 5.11 regressing for AMD performance on Zen 2 and newer systems where the just-added CPU frequency invariance support was often hurting various workloads when using the default "Schedutil" scheduler utilization frequency scaling governor. Since then and through the holidays I have been carrying out many more benchmarks looking at the Linux 5.11 performance with a particular focus on the AMD desktop/server platforms.

Long story short, the new AMD frequency invariance support found with Linux 5.11


Intel Keem Bay Accelerated Hashing Driver Positioned For Linux 5.12

Keem Bay , Intel's third-generation Movidius VPU (Vision Processing Unit), continues seeing more upstream open-source hardware support within the Linux kernel. Coming to the Linux 5.12 kernel in a couple months will be more support within the crypto subsystem.

The Keem Bay VPU features much faster inference performance over its predecessors and intended for edge computing with use-cases from drones to other computer vision scenarios. The ARM-based SoC that is part of Keem Bay has yielded a lot of upstream kernel

RADV Vulkan Driver Begins Landing Optimizations For AMD Smart Access Memory

Following RadeonSI seeing optimizations around AMD Smart Access Memory (Resizable BAR) support last month, the Radeon Vulkan driver "RADV" within Mesa 21.0 is also seeing similar treatment.

Linux has been seeing more work in recent weeks around Smart Access Memory / Resizable BAR support and that continued this morning with Mesa 21.0 Git seeing the initial RADV support.

MR 7979 merged today to Mesa 21.0 now makes use of vRAM for the command submission and upload buffer if all vRAM is
