Switching from the "Radeon" to "AMDGPU" kernel driver on Linux is possible for Radeon GCN 1.0/1.1 era graphics cards and doing so can mean slight performance benefits, the ability to run the AMDVLK or RADV Vulkan drivers, and simply making use of this better maintained driver. But having these original GCN graphics cards default to the modern AMDGPU driver appears held up by the lack of analog video output support with that driver...

The Linux kernel work for making use of the x86_64 FSGSBASE instruction since Intel Ivy Bridge and since then AMD CPUs also is set to finally land with the in-development Linux 5.9 kernel. The FSGSBASE support has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side...

The Linux 5.9 kernel merge window will open up immediately upon the release of Linux 5.8, which is expected to happen this evening unless Linus Torvalds decides to stave it off for one week to allow for additional testing. In any case, once Linux 5.9 kicks off there are a lot of changes expected...

Incredibly it has taken until now with Wine-Staging 5.14 to implement more than just a stub to Wine's FINDSTR program implementation. Yes, the long-standing command to search for strings...

A few days back we wrote of Intel's ISPC compiler landing GPU code generation support for their UHD/Iris/Xe Graphics from Gen9 Skylake and beyond. Following that code being merged, ISPC 1.14.0 was quickly tagged...

While some platforms like Netmarketshare have reported increases month-over-month for Linux desktop usage, that doesn't appear to be translating similarly to the Linux gaming market-share, or at least not at the rate Steam is growing on Windows and macOS. Valve has just published their July 2020 numbers that are part of the Steam Survey...

Primarily driven currently by Arm big.LITTLE use-cases like high-end smartphones where you may be running on battery and not want to boost the CPU performance too high for real-time (RT) tasks, Linux 5.9 is adding new capabilities around setting the default boost value...
