RADV Graphics Pipeline Library Support Becoming Speedy, Aims For Mesa 23.1 Promotion
RADV Graphics Pipeline Library Support Becoming Speedy, Aims For Mesa 23.1 Promotion
29 January 07:17 AM EST - Radeon - RADV Graphics Pipeline Library - 9 Comments

The Mesa Radeon Vulkan "RADV" driver's implementation of the graphics pipeline library (VK_EXT_graphics_pipeline_library) is becoming much faster thanks to fast-linking and various pending fixes. In turn this will get games making use of the extension the ability to ideally have no shader pre-caching while still enjoying no in-game stuttering. Valve's Linux graphics driver developers working on RADV have been working through some issues with the RADV graphics pipeline library and for Mesa 23.1 looks like it could be in good shape.

27 January 11:00 AM EST - Radeon - RADV Register Shadowing - 19 Comments

Most of the Mesa Radeon Vulkan "RADV" driver development has been done by the likes of Valve, Google, and Red Hat engineers with it being an "unofficial" driver while AMD supports AMDVLK as their official open-source Vulkan driver as well as supporting their closed-source AMDGPU-PRO Vulkan driver too that shares common code with their Windows Vulkan driver. It was pleasant to see AMD this week though submitting new feature code to RADV.

Linux Developers Evaluating New "DOITM" Security Mitigation For Latest Intel CPUs
Linux Developers Evaluating New "DOITM" Security Mitigation For Latest Intel CPUs
27 January 07:00 AM EST - Software - 26 Comments

Last summer Intel published guidance around the Data Operand Independent Timing (DOIT) instruction mode that can be enabled with recent generations of Intel processors to ensure constant time execution for a subset of the Intel instruction set, which can be particularly important for cryptographic algorithms. Linux kernel developer discussions fizzled out last year over handling this DOIT functionality for what is described as a CPU vulnerability with recent Intel CPUs. However, now a Linux kernel patch from a Google developer would enable this change unconditionally for newer Intel CPUs but raises performance concerns.

Earlier this month Intel announced they would be discontinuing development of HAXM as a hardware-accelerated execution manager that's been popular on Windows and macOS for Android emulation. While the original announcement discontinued its development immediately, they decided to go ahead and put out one final version: Intel HAXM 7.8 is available today for concluding this open-source project.

Linux 6.3 EDAC Prepares For Intel Granite Rapids With Up To 12 DDR5 Memory Channels
26 January 12:00 PM EST - Intel - i10nm EDAC - Add A Comment

Intel open-source engineers continue to be quite busy in bringing up the Linux support for Emerald Rapids as the successor to Sapphire Rapids and then as well for Granite Rapids as the Xeon Scalable processors following that. With the i10nm EDAC changes queued up ahead of Linux 6.3, there is support through Granite Rapids as well as confirming Granite Rapids supporting up to 12 channel DDR5 system memory.

BSD-Powered helloSystem 0.8 Performance Against Linux On AMD Zen 4
26 January 08:00 AM EST - Operating Systems - 33 Comments

With many Phoronix readers having been excited by the recent helloSystem v0.8 release as a FreeBSD-powered OS taking major design inspiration from Apple's macOS, I decided to run some benchmarks to see how this FreeBSD 13.1 based operating system was competing with a few different Linux distributions from an AMD Ryzen 9 7950X (Zen 4) desktop.

Arm Helping With AArch64 Rust Linux Kernel Enablement
25 January 02:30 PM EST - Arm - AArch64 + Rust + Linux Kernel - 12 Comments

Much of the Rust programming language support/infrastructure for the Linux kernel thus far has been with an x86_64 focus while obviously AArch64 is an important target as well. It's nice to see Arm Limited engineers working on the Rust Linux kernel support for AArch64/ARM64.

Google Engineer Introduces "Light AVX" Support Within LLVM
25 January 09:00 AM EST - LLVM - Light AVX - 5 Comments

Google engineer Ilya Tocar has introduced the notion of "light" AVX support within the LLVM compiler infrastructure for utilizing some benefits of Advanced Vector Extensions (AVX) but trying to avoid the power/frequency impact that AVX-512 use has on older generations of Intel processors.

AMD Publishes New Firmware Binaries For Upcoming Hardware
