Wine 8.9 closes a 17-year-old bug
We have here new Winewhich brings, among the news, the update of the Mono engine to version 8.0.0, the completion of the conversion of the PostScript driver to the Portable Executable format, the support of the Doppler shift in DirectSound and the acceleration of GdiPlus.
A total of 16 bugs have been fixed (or closed), among which the oldest is bug 3452 regarding the slow running of the legendary game Battlecruiser 3000AD. It was reported in October 2005, the discussion around the bug is traditionally fun, with one user reporting in 2018 that it seems the bug no longer appears and now another X years later it is now closed, while also addressing possible running under DOSBOX ( and they also didn’t seem to close the whole thing with the status ABANDONED or WORKSFORME).
The fastest patched is Microsoft Visio 2003 runtime bug 54982, which only took 5 hours to close, having already been resolved earlier in another report. Well, so actually there are actually not 16 fixed bugs, but such is the hectic development of the Wine project.
AMD GPU driver update to support color management
From work Melissy Wen (Igalia) in cooperation with developers at AMD and Valve will first benefit Steam Deck consoles and then regular Radeons as well. It’s about developing color management support for AMD GPUswhich primarily targets the Steam Deck, but since this portable console carries an AMD “Van Gogh” APU, the code will of course also reach regular Radeons.
Last month, Melissa prepared RFC patches specifically for AMDGPU color management, introducing pre- and post-blending color properties and various things around color management into the chain. In addition to the Linux kernel, Valve is preparing the necessary things within the Gamescope compositor that SteamOS uses, which will add support for color gamut mapping, HDR in general, SDR→HDR and HDR→SDR, etc. More in the relevant a series of 36 patches by Melissa.
Intel Open Image Denoise 2.0 runs on the GPU
With the new version of the open denoiser from Intel comes the use of SYCL for Intel Xe GPUs, of course also usable with Nvidia GPUs through the CUDA interface or AMD through HIP. Open Image Denoise 2.0which is part of Intel oneAPI, is here.
Open Image Denoise, i.e. a fast denoiser primarily for use in raytracing, has been in oneAPI for a long time, but until now it only ran via the CPU. The new version can now also run on GPUs, regardless of the manufacturer. Other innovations include, for example, asynchronous execution, physical device API for queues of available devices in the system, etc. The code is available under the Apache 2.0 license at GitHub projectmore detailed information is also available on a separate OID website.
Linux will get a hybrid SMP fix so that new laptops are not detected as 11-socket machines
That there will be a lot of fun with hybrid CPU architectures was clear even before the introduction of the first processors of the Alder Lake family. In addition to all the tuning of schedulers for the most efficient distribution of tasks between cores and threads, a hybrid multiprocessing fix is now coming to Linux, so that the new generation of hybrid CPUs for notebooks does not look like a bizarre monster machine with 11 CPU sockets in the system.
He’s fixing himself appears in the Linux 6.4 kernel and will be backported to older versions as well. Corrects the reported CPU topology for Intel hybrid CPUs, which will change again with the Meteor Lake generation (let’s add that it only applies to laptops: ML is not aimed at desktops due to problems with the production of larger CPU dies with more cores). Current Linux does not work properly with hybrid SMP/variable smp_num_siblings, so Meteor Lake looks like an 11-socket, 1-core CPU machine instead of a 16-core CPU in 1 socket. In addition to the smiling reporting of such a configuration to the user-space, this also causes confusion for the scheduler, which thus does not plan the optimal distribution of tasks across CPU threads.
He comments on everything in more detail Zhang Rui from Intel v proposed patch.
Night mode in KDE Plasma 6.0 will also work with Nvidia GPUs on Wayland
Nate Graham he claims, that the biggest innovation in the development of Plasma 6.0 is the support for night mode with Nvidia GPUs on Wayland as well, and there is no reason not to believe it. Nvidia needs a specific approach here because of the way it works with the Gamma LUT. Plasma 6.0 will thus support the given thing on GeForce-type cards, although the solution is not optimal, just decently functional (so we can expect that we will hear more about the problem in the coming months). Thanks are due Xavieru Huglovi.
Furthermore, the developers worked on searching for very short strings in Krunner (those with 2 or 3 characters now get more relevant results), navigation in system settings using the keyboard (plus here we find a new look). Došo also fixes many errors, a total of 76 reported ones are closed.
