64-bit ARM Linux Kernel Against CPU-Specific Optimizations: "Pretty Unmaintainable"

While micro-architecture specific optimizations are rather common place within the Linux x86_64 kernel for various Intel and AMD CPU families with various performance tricks, the ARM64 Linux kernel maintainers are against introducing new micro-architecture specific optimizations as it affects new ARM processors…

SiFive Gets Newer AMD Radeon GPUs Working On RISC-V

Thanks to AMD’s Linux graphics drivers being open-source, they can be easily ported/adapted for new CPU architectures. For years older AMD Radeon GPUs have been working great on RISC-V such as shown in my HiFive Unmatched review back in 2021 with a Radeon graphics card in the PCI Express x16 slot. But newer AMD Radeon GPUs hadn’t worked out-of-the-box due to AMDGPU’s “DC” display code but that is changing with new patches from SiFive they are allowing the latest AMD GPUs to work on RISC-V…

Intel Fixes Microcode Bug that Could Expose Your Sensitive Data

It was discovered that a sequence of processor instructions for some Intel processors leads to unexpected behavior that could allow an authenticated local user to escalate privileges (CVE-2023-23583). This bug, dubbed “Reptar,” could expose sensitive information or cause system crashes, resulting in a denial of service.
