Zen 2 is a computer processor microarchitecture by AMD.It is the successor of AMD's Zen and Zen+ microarchitectures, and is fabricated on the 7 nanometer MOSFET node from TSMC.The microarchitecture powers the third generation of Ryzen processors, known as Ryzen 3000 for the mainstream desktop chips (codename "Matisse"), Ryzen 4000U/H (codename "Renoir") and Ryzen 5000U (codename "Lucienne KVM Archive on lore.kernel.org help / color / mirror / Atom feed * [PATCH] kvm: svm: Intercept RDPRU @ 2019-09-19 22:59 Jim Mattson 2019-09-20 20:44 ` Krish Sadhukhan 2019-09-24 14:16 ` Paolo Bonzini 0 siblings, 2 replies; 4+ messages in thread From: Jim Mattson @ 2019-09-19 22:59 UTC (permalink / raw) To: kvm; +Cc: Jim Mattson, Drew Schmitt, Jacob Xu, Peter Shier The RDPRU instruction gives Source of the Rust file `src/extended.rs`. the two new ones (8 and 9) could likely be moved arbitrarily ahead (as a pair, not 9 ahead of 8), if others are to be further delayed. 1: x86: determine have_as_* just once 2: x86: move back clang no integrated assembler tests 3: x86emul: support movdir {i,64b} insns 4: x86emul: support enqcmd insn 5: x86/hvm: scale mperf values reported to … On Jan 23 02:06, Brian Inglis wrote: > rdpru flag is cpuid xfn 80000008 ebx bit 4 added in linux 5.5; > see AMD64 Architecture Programmerâ s Manual Volume 3: ^^^^^ This came over already broken.
