I need folks to test some code committed recently for identifying the number of cpu's on a machine. The plan is to use this code to choose an SMP or UP kernel during an install. cd /usr/src/tools/tools/ncpus make su ./ncpus You should get output like this: trouble# ./ncpus acpi0_check: nexus0 attached acpi0_check: legacy0 not-present acpi0_check: npx0 attached acpi0_check: acpi0 attached ncpus: MADT: Found CPU APIC ID 1 enabled ncpus: MADT: Found CPU APIC ID 2 disabled acpi: 1 ncpus: MPTable: Found CPU APIC ID 0 enabled mptable: 1 acpi: 1 means checking ACPI configuration info we found 1 cpu. mptable: 1 means MPTable indicated there was 1 cpu. The rest of the stuff printed out is for debugging. If you run this test and DON'T see the correct number of cpus for your machine please mail me (directly) with the output and dmesg output from booting your kernel. FWIW acpi info is considered more definitive than MPTable so if acpi gives you the right answer but MPTable does not that's ok. Sam
