From 0f203430dd88cc6270310956ace58aca639edb59 Mon Sep 17 00:00:00 2001 From: He Chen Date: Thu, 27 Apr 2017 10:35:58 +0800 Subject: numa: Allow setting NUMA distance for different NUMA nodes This patch is going to add SLIT table support in QEMU, and provides additional option `dist` for command `-numa` to allow user set vNUMA distance by QEMU command. With this patch, when a user wants to create a guest that contains several vNUMA nodes and also wants to set distance among those nodes, the QEMU command would like: ``` -numa node,nodeid=0,cpus=0 \ -numa node,nodeid=1,cpus=1 \ -numa node,nodeid=2,cpus=2 \ -numa node,nodeid=3,cpus=3 \ -numa dist,src=0,dst=1,val=21 \ -numa dist,src=0,dst=2,val=31 \ -numa dist,src=0,dst=3,val=41 \ -numa dist,src=1,dst=2,val=21 \ -numa dist,src=1,dst=3,val=31 \ -numa dist,src=2,dst=3,val=21 \ ``` Signed-off-by: He Chen Message-Id: <1493260558-20728-1-git-send-email-he.chen@linux.intel.com> Reviewed-by: Igor Mammedov Reviewed-by: Andrew Jones Signed-off-by: Eduardo Habkost --- include/hw/acpi/aml-build.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/hw/acpi/aml-build.h') diff --git a/include/hw/acpi/aml-build.h b/include/hw/acpi/aml-build.h index 00c21f160c..329a0d0c90 100644 --- a/include/hw/acpi/aml-build.h +++ b/include/hw/acpi/aml-build.h @@ -389,4 +389,5 @@ GCC_FMT_ATTR(2, 3); void build_srat_memory(AcpiSratMemoryAffinity *numamem, uint64_t base, uint64_t len, int node, MemoryAffinityFlags flags); +void build_slit(GArray *table_data, BIOSLinker *linker); #endif -- cgit v1.2.3
