From 4ad0475f035e4830d233577b55e6ff20feb6afc2 Mon Sep 17 00:00:00 2001 From: Ed Maste Date: Wed, 23 Oct 2019 19:35:26 +0000 Subject: [PATCH] arm64: enable options NUMA in GENERIC As with amd64 NUMA is required for reasonable operation on big-iron arm64 systems and is expected to have no significant impact on small systems. Enable it now for wider testing in advance of FreeBSD 13.0. You can use the 'vm.ndomains' sysctl to see if multiple domains are in use - for example (from Cavium/Marvell ThunderX2): # sysctl vm.ndomains vm.ndomains: 2 No objection: manu Sponsored by: The FreeBSD Foundation --- sys/arm64/conf/GENERIC | 1 + 1 file changed, 1 insertion(+) diff --git a/sys/arm64/conf/GENERIC b/sys/arm64/conf/GENERIC index 96db964b68c7..541140e9301b 100644 --- a/sys/arm64/conf/GENERIC +++ b/sys/arm64/conf/GENERIC @@ -25,6 +25,7 @@ makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support options SCHED_ULE # ULE scheduler +options NUMA # Non-Uniform Memory Architecture support options PREEMPTION # Enable kernel thread preemption options VIMAGE # Subsystem virtualization, e.g. VNET options INET # InterNETworking
