Development version of Wine 8.12
Only two minor innovations are offered by the new one development version of Wine 8.2. The first one is the initial support for “painting windows” (?) in the Wayland driver, the second one is about improving the performance of WineD3D. A decent 31 bugs are fixed, with the oldest reported from 2007 being closed after over 16 years, the fastest patched after just 1 day addressing a rogue build of Wine with Clang 11.0.1.
NTFS driver in Linux 6.5 slightly faster
With Linux 5.15, the kernel NTFS file system driver from Paragon is included will see another minor efficiency improvement in Linux 6.5. Konstantin Komarov from Paragon Software is responsible for the latest optimization. The NTFS3 driver also now supports the volinfo and label attributes accessible through sysfs, an alternative boot mode can also be used in case of damage to the primary boot.
There were also fixes for CPU endian, solving some problems in the logic and also partial refactoring of the code. Overall, this is a decent incremental improvement to a file system driver that’s been with us for 30 years, and we’re not going to get rid of it in the IT world anytime soon.
Better support for PS/2 keyboards and mice in Linux 6.5
If it defines anything obsolete peripherals where mice fly in thousands of dpi and keyboards play with millions of lights and dozens of macros, it’s the good old PS/2 interface. It can still be found on motherboards for the latest CPUs, in cheaper models, where it is also possible that they will serve “Ms. Rose” in her office PC with the same PS/2 keyboard from 1998, before they both retire. So here we have the upcoming Linux 6.5, which will receive minor improvements just for this interface.
The whole thing was taken care of by the administrator of the relevant part of the kernel, Dmitry Torokhov. These are minor adjustments to the behavior around the keyboard controllers and their scancode in the output buffer, where if the kernel is just initializing the whole thing and waiting for an ACK, it cannot receive this signal (now it can) and deal with things like setting the LED on the keyboard ( here it must be stated that this still sometimes glitches on Linux) – a typical scenario was, for example, that if the user pressed CapsLock (and the guest sent a command to change the state of the CapsLock LED) at the same time as the keyboard was sending an interrupt signal, confusion could occur cores.
Intel Xeon Max Sapphire Rapids can beat AMD EPYC by hundreds of percent
A generally valid fact of recent years is that AMD offers processors with higher performance than Intel, at the same time with lower consumption. At the same time, it benefits from TSMC’s 7nm and 5nm EUV process, compared to Intel’s inferior manufacturing processes such as Intel 7 (which is de facto a tuned 10nm process). Nevertheless, there are situations when Intel processors are simultaneously more powerful and more economical, with hundreds of percent more performance and tens of percent less consumption at the same time. One such test has now been conducted by Phoronix.
If we take as the flagship of this test a pair of 56-core Xeon Max 9480 with HBM2e memory and AMX (Advanced Matrix eXtensions) support versus a pair of 96-core EPYCs 9654, we have to reach for the stated test results for a very narrow group, which is, however, dominant, for which actually new Xeons were born: tests of FP16 AI calculations using the OpenVINO (Open Visual Inference and Neural network Optimization) package.
We will not replicate the measurements here, everything can be read at Phoronixlet’s just state that after averaging all partial tests, the pair of Xeons achieves roughly 150% of the performance of the pair of processors from AMD, while the consumption of this solution is on average below 600 W, while AMD is on average above this value and in the peak it attacks and even exceeds the 700 W limit .
AMD Advanced Media Framework 1.4.30 adds a fallback for ffmpeg
AMD’s cross-platform framework for video processing on both Windows and Linux, Advanced Media Framework, or AMF, has a new SDK version 1.4.30. In addition to the otherwise supported AVC, HEVC and AV1 video encoding on the GPU, it also adds a fallback in the form of wrappers for CPU encoding via the standard ffmpeg package.
AMD has also prepared various improvements in the AV1 format, support for multi-monitor configurations has also been added in the sample DVR application, and the ffmpeg library is upgraded to version 5.1.2. The details are available on the GPUOpen website.
