From: Edgar Su Date: Mon, 12 Jul 2021 13:22:48 +0000 (+0800) Subject: x86: kernel: set NR_CPUS to 512 X-Git-Tag: v22.03.0-rc1~2159 X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=df554e6fcab171ec499d8fb2ed10a0da328323f3 x86: kernel: set NR_CPUS to 512 NR_CPUS limits the number of CPUs supported to 8. This makes total sense on hardware-restircted platforms, but not on x86_64, where CPUs with more than 8 cores can be easily acquired and with less physical limitaions. see also: https://forum.openwrt.org/t/x86-64-8-cpu-limitation-on-vanilla-release/100946 Signed-off-by: Edgar Su --- diff --git a/target/linux/x86/64/config-5.10 b/target/linux/x86/64/config-5.10 index 2db2f4998b..6804d83519 100644 --- a/target/linux/x86/64/config-5.10 +++ b/target/linux/x86/64/config-5.10 @@ -301,8 +301,8 @@ CONFIG_NEED_DMA_MAP_STATE=y CONFIG_NET_FAILOVER=y CONFIG_NET_FLOW_LIMIT=y # CONFIG_NITRO_ENCLAVES is not set -CONFIG_NR_CPUS=8 -CONFIG_NR_CPUS_DEFAULT=64 +CONFIG_NR_CPUS=512 +CONFIG_NR_CPUS_DEFAULT=512 CONFIG_NR_CPUS_RANGE_BEGIN=2 CONFIG_NR_CPUS_RANGE_END=512 CONFIG_NVME_CORE=y diff --git a/target/linux/x86/64/config-5.4 b/target/linux/x86/64/config-5.4 index b97b9f64c1..50521a5148 100644 --- a/target/linux/x86/64/config-5.4 +++ b/target/linux/x86/64/config-5.4 @@ -312,8 +312,8 @@ CONFIG_ND_CLAIM=y CONFIG_NEED_DMA_MAP_STATE=y CONFIG_NET_FAILOVER=y CONFIG_NET_FLOW_LIMIT=y -CONFIG_NR_CPUS=8 -CONFIG_NR_CPUS_DEFAULT=64 +CONFIG_NR_CPUS=512 +CONFIG_NR_CPUS_DEFAULT=512 CONFIG_NR_CPUS_RANGE_BEGIN=2 CONFIG_NR_CPUS_RANGE_END=512 # CONFIG_NUMA is not set
