Revised AVX-512 xor_gen() Implementation For Linux RAID Yielding More Performance Gains

A few days back I wrote about Google's Eric Biggers spearheading an AVX-512 implementation of xor_gen() as the Linux kernel function used for generating and validating parity blocks such as for RAID5/RAID6. That initial implementation was yielding up to 41% better performance while a new implementation has now been posted for scoring some additional victories...

GCC 17 Merges Function Multi-Versioning For APX & AVX10.2

Earlier this month I wrote about Intel working on function multi-versioning support for APX and AVX10.2 with the GCC compiler. This allows developers to write optimized code paths specifically targeting Advanced Performance Extensions (APX) or Advanced Vector Extensions 10.2 capabilities of future processors while being able to otherwise fall-back to generic or other optimized code paths for other ISA target features. This work is now merged for GCC 17...

Open-Source Success Achieved For Greater Transparency & Security: Running AMD openSIL + Coreboot On EPYC

Ever since AMD announced openSIL in early 2023 for open-source CPU silicon initialization to eventually replace AGESA and enhance their Coreboot support, I have been eager to try it out. The openSIL code drops to date though have just focused on select reference platforms with only aiming for production status in the Zen 6 timeframe. But thanks to 3mdeb porting openSIL and Coreboot to a Gigabyte server motherboard, it's now possible to try out openSIL+Coreboot right now on Zen 5 hardware.
