From ca247bf6d895df3641a26cf4c3b5c701a1d71c2f Mon Sep 17 00:00:00 2001 From: Lin Guo Date: Wed, 11 Sep 2024 14:33:54 -0700 Subject: [PATCH] Remove `PDCM` from the sapphirerapids list `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 5e1b285..1c27c26 100644 --- a/cpu/microarchitectures.json +++ b/cpu/microarchitectures.json @@ -1482,7 +1482,6 @@ "cldemote", "movdir64b", "movdiri", - "pdcm", "serialize", "waitpkg" ],
