Last week Valve formally announced their new Radeon shader compiler for AMD's open-source Linux graphics drivers. At this stage it's an out-of-tree solution providing generally faster performance to the Mesa RADV Vulkan driver over the current AMDGPU LLVM shader compiler but they also have ambitions of wiring it up to the RadeonSI OpenGL driver once mature too, assuming AMD's developers are willing to make use of this new compiler code. For those wondering about the Vulkan performance, here are our independent benchmarks of the current Mesa 19.2 RADV performance with the LLVM shader compiler compared to Valve's new "ACO" compiler back-end and then also using AMD's official AMDVLK reference driver that is also leveraging LLVM.

Following last night's Linux 5.2 kernel release, the GNU folks maintaining their GNU Linux-libre off-shoot that de-blobs the kernel of being able to load binary-only firmware/microcode files or the ability to load binary-only kernel modules is out with their re-based kernel...

As outlined yesterday, AMD's Ryzen 3000 processors are very fast but having issues booting newer Linux distributions. The exact issue causing that boot issue on 2019 Linux distribution releases doesn't appear to be firmly resolved yet but some are believing it is an RdRand instruction issue on these newer processors manifested by systemd...

Thomas Gleixner sent in his various x86 code updates early this morning for the just kicked off Linux 5.3 kernel cycle...

The GPIO updates for the newly-opened Linux 5.3 kernel merge window is dropping the FMC subsystem as they deem it easier to re-start from scratch writing that code than to try to repair it, or "start over using the proper kernel subsystems than try to polish the rust shiny." Funny enough, this code is being used by the CERN's well known Large Hadron Collider...

The past several years Siemens and others have been working on Jailhouse as a Linux-based partitioning hypervisor for bare metal appliances. Their previous release was all the way back during last year's Oktoberfest and now with construction for this year's fest kicking off at the wiesn, the developers happen to be releasing their next version of Jailhouse...

Adding to the excitement of 7 July is the release of the Linux 5.2 stable kernel, which also means the opening of the Linux 5.3 merge window...

Leading up to today's Radeon RX 5700 "Navi" series launch it was looking like there wouldn't be any support within Mesa's Radeon "RADV" Vulkan driver for this community-maintained open-source implementation. But the open-source developers at Valve managed to not only deliver Navi 10 support but also Navi 12 and Navi 14 are also supported with this new Mesa 19.2 code...

As a follow-up to this morning's Radeon RX 5700 / RX 5700 XT Linux benchmarks, AMD has now published a packaged launch-day Linux driver for those wanting to use these new RDNA/Navi graphics cards on Linux without building your own kernel/Mesa/libdrm/LLVM... Well, assuming you are on Ubuntu 18.04 LTS...

After weeks of anticipation, we can now share how the AMD Ryzen 7 3700X and Ryzen 9 3900X performance is under Linux. These first Zen 2 processors do indeed deliver a significant improvement over Zen/Zen+ processors and also battle Intel's latest 14nm CPUs but for Linux users there is one big, unfortunate issue right now.

While last month we could talk all about the specifications for the Radeon RX 5700 series, today the embargo has lifted concerning the Radeon RX 5700/5700XT graphics cards so we can finally talk about the actual (Linux) performance. The road is a bit rougher than we had hoped, but it's possible to drive these new Navi graphics cards today using their open-source graphics driver stack at least for OpenGL games/applications. Over the weeks ahead, the Linux driver support for Navi will continue to improve.
