From 0c7bd58859cdf23cc3e71dca8ee0424c21b86f4f Mon Sep 17 00:00:00 2001 From: Lin Guo Date: Mon, 14 Oct 2024 02:11:36 -0700 Subject: [PATCH] Remove `PDCM` from the sapphirerapids list (#119) `PDCM` is not a feature currently used by compilers, see for instance https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html. For GCP VMs, only ones that have vPMU [enabled](https://cloud.google.com/compute/docs/manage-pmu-in-vms) would have `PDCM` exposed in the guest. Including `PDCM` would therefore cause these non-vPMU-enabled VMs to be identified as icelake instead. --- cpu/microarchitectures.json | 1 - 1 file changed, 1 deletion(-) diff --git a/cpu/microarchitectures.json b/cpu/microarchitectures.json index 7e97d29..9275422 100644 --- a/cpu/microarchitectures.json +++ b/cpu/microarchitectures.json @@ -1482,7 +1482,6 @@ "cldemote", "movdir64b", "movdiri", - "pdcm", "serialize", "waitpkg" ],
