LLVM Clang 16 vs. GCC 13 Compiler Performance On AMD 4th Gen EPYC "Genoa"

With the recent stable releases of LLVM’s Clang 16 and GCC 13 compilers there is now initial AMD Zen 4 “znver4” support in these open-source compilers. Curious about the performance difference between these two compilers on the very newest AMD 4th Gen EPYC “Genoa” server processors, I ran some LLVM Clang 16.0 and GCC 13.1 benchmarks on the flagship EPYC 9654 2P Linux server.

Intel Posts Latest 113 Patches For Linux KVM TDX Support

One of the new features of Intel Xeon Scalable 4th Gen “Sapphire Rapids” server processors is support for Trust Domain Extensions (TDX) but for this generation is only being activated for CPUs going to select cloud providers. Intel TDX allows better isolating virtual machines from the VMM/hypervisor and other non-TD software on the platform. This limited roll-out of Intel TDX has worked out okay with the Linux support for this security feature still being in flux. Sent out today was the 14th spin of the 113 patches needed for getting KVM TDX support wired up within the Linux kernel…

Linux Lands Fix For Potentially Bogus Number Of Intel Hybrid CPU HT Siblings

A few days ago I wrote about a Linux kernel patch being prepared for fixing Intel hybrid CPU SMP/HT topology reporting due to the way the Linux kernel was currently counting the number of Hyper Threading siblings for each core. Fortunately, that fix which is apparently becomes more pressing for upcoming Meteor Lake processors, has now been picked up in time for today’s Linux 6.4-rc4 release and is set for back-porting to stable kernel series…
