With the ACO shader compiler back-end merged for Mesa 19.3 as of mid-September and more improvements merged since then, it's now very easy to try out this alternative to AMD's longstanding AMDGPU LLVM compiler back-end. ACO, which is developed by Valve and their contractors outside of AMD, is looking quite good not only for quicker shader compilation (more punctual game load times) but also helping the performance of some Vulkan-powered games. Here are our latest ACO benchmarks.

[4 minuty čtení] Vyšel MX Linux 19 Beta 3, vyšlo FreeBSD 12.1-BETA3, AMD je na vzestupu i v enterprise segmentu a možná chystá Zen 3 s 4×SMT, TSMC rozjede 5nm proces v březnu. Tým projektu FreeBSD pozvolna finišuje práce na prvním aktualizačním vydání v rámci nejnovější řady 12. Čekat tak sice nemůžeme převratné novinky, ale „jedničkové“ aktualizace jsou typicky tím, na co mnozí admini čekají – vychytané chyby a pár drobností navíc. Zde dochází k několika opravám, jejichž stabilitu je možno v rámci třetí beta verze testovat.

With the surprise code drop of Google developing a new open-source AV1 video decoder as "libgav1", I set out this Saturday to run benchmarks on various systems for seeing how the performance is looking for this CPU-based decoder in relation to the more well known DAV1D decoder...

Coming out of informal discussions from this week's X.Org Developers Conference in Montreal, a "liboutput" library has been proposed as a theoretical new library for helping to bring up Wayland compositors, X11 window managers, and anything else wanting to interface with DRM/KMS kernel interfaces...

We were alerted this morning to a CPU bug resulting in crashes for Intel Geminilake processors. At least Chrome and Firefox are affected but sounds like other software may be affected too, just that Google has enough engineering resources for investigating the issue...

Just one week after the release of Radeon Open Compute 2.8, AMD has now released ROCm 2.9 as the newest feature release for this open-source GPU Linux compute stack for Radeon hardware...

With less than two weeks to go until the Ubuntu 19.10 release, on Friday the experimental ZFS root file-system install support was merged into the Ubuntu desktop "Ubiquity" installer...

Intel's open-source crew on Friday released version 19.39.14278 of their compute/OpenCL runtime...

While there exists DAV1D as one of the most promising AV1 decoders to date, Google has been developing libgav1 as its own AV1 decoder and focused on Arm-powered Android devices but also x86_64 desktop CPUs as well...

O víkendu 5. a 6. října probíhá v pražských Dejvicích osmý ročník konference LinuxDays. Opět můžete shlédnout desítky přednášek, zúčastnit se workshopů nebo navštívit zajímavé stánky projektů.

For the past year "Zink" has been in development as the OpenGL API implemented over Vulkan and done as a Gallium3D driver. That code by Collabora's Erik Faye-Lund will likely be merged to Mesa 19.3 in the coming weeks...

Linux 5.4 is already exciting with its many new features and changes but was made even more so on Friday night with the honoring of the latest DRM fixes pull request that includes the "fix" of enabling LRU bulk moves for the AMDGPU DRM driver!..

Pod slovem kultura si každý představí něco jiného. Někdo večer strávený v divadle, jiný mocnou civilizaci a další marně přemítá, co že to slovo znamená, ale raději doufá, že ať je to cokoli, snad se mu to vyhne.

DXVK 1.4.2 is out as another weekly update to this Direct3D 11 over Vulkan translation library used by Wine / Proton for accelerating Windows games on Linux...

AMD provided an update on their Linux FreeSync/Adaptive-Sync support at this week's X.Org Developers Conference event in Montreal. There's good news both for HDMI and Wayland Linux users with Radeon graphics...

Complementing the 18-way NVIDIA GPU compute comparison from earlier this week with now having our hands on the RTX 2060/2070/2080 SUPER graphics cards, this round of NVIDIA Linux testing is looking at the Blender 2.80 and LuxCoreRender 2.1/2.2 performance for these popular rendering programs that offer CUDA acceleration.

In addition to Intel announcing their work on the new "IBC" compiler back-end for their OpenGL/Vulkan drivers, the developers working on the Radeon "ACO" in cooperation with Valve were presenting the latest work on their compiler back-end at this week's XDC 2019 event in Canada...

The Logitech G15 keyboards and related gaming keyboards from the company are seeing a new open-source driver queued ahead of the Linux 5.5 kernel cycle...

Following the Spectre mitigations coming to light last year, the late microcode update process for CPUs was serialized. However, this has led to complaints from cloud vendors and other customers with large core count servers where downtime/disruptions need to be minimal. So now the CPU microcode update process is being parallelized again...

Systemd has begun harvesting the automatic suspend rules from ChromeOS for determining which USB devices support automatic suspend well out-of-the-box on Linux...
