I've a problem with managing power consumption on Intel Nehalem CPU.I've installed Xen 3.4 on our Dell PowerEdge T610 system on a Ubuntu 9.04 distribution. I recompiled the kernel 2.6.30rc5. Now I can see the c-states of the CPUs but no access to P-states information and the frequency scaling does not work. By the way, if I run the kernel 2.6.28.13 which is the last one supported by Ubuntu, I have access to the frequency data but not to the one of power consumption. I report below some data I gathered form my machine. Hope someone could be of help Regards Danilo Ardagna ---- xm dmesg __ __ _____ _ _ _ ____ \ \/ /___ _ __ |___ /| || | / | _ __ ___| ___| \ // _ \ '_ \ |_ \| || |_ | |__| '__/ __|___ \ / \ __/ | | | ___) |__ _|| |__| | | (__ ___) | /_/\_\___|_| |_| |____(_) |_|(_)_| |_| \___|____/(XEN) Xen version 3.4.1-rc5 (root@xxxxxxxxxxxxxx) (gcc version 4.3.3 (Ubuntu 4.3.3-5ubuntu4) ) Fri Jul 3 17:35:33 CEST 2009 (XEN) Latest ChangeSet: Thu Jul 02 16:17:12 2009 +0100 19679:ddf8e5917a12 (XEN) Command line: cpufreq=xen (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: V2; EDID transfer time: 1 seconds (XEN) Disc information: (XEN) Found 2 MBR signatures (XEN) Found 2 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 00000000000a0000 (usable) (XEN) 0000000000100000 - 00000000cf699000 (usable) (XEN) 00000000cf699000 - 00000000cf6af000 (reserved) (XEN) 00000000cf6af000 - 00000000cf6ce000 (ACPI data) (XEN) 00000000cf6ce000 - 00000000d0000000 (reserved) (XEN) 00000000e0000000 - 00000000f0000000 (reserved) (XEN) 00000000fe000000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 0000000230000000 (usable) (XEN) System RAM: 8182MB (8378596kB) (XEN) ACPI: RSDP 000F1640, 0024 (r2 DELL ) (XEN) ACPI: XSDT 000F1744, 009C (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: FACP CF6C3F9C, 00F4 (r3 DELL PE_SC3 1 DELL 1) (XEN) ACPI: DSDT CF6AF000, 320F (r1 DELL PE_SC3 1 INTL 20050624) (XEN) ACPI: FACS CF6C6000, 0040 (XEN) ACPI: APIC CF6C3478, 015E (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: SPCR CF6C35D8, 0050 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: HPET CF6C362C, 0038 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: DMAR CF6C3668, 01E0 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: MCFG CF6C38C4, 003C (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: WDAT CF6C3904, 0134 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: SLIC CF6C3A3C, 0024 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: ERST CF6B2390, 0270 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: HEST CF6B2600, 027C (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: BERT CF6B2210, 0030 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: EINJ CF6B2240, 0150 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: SRAT CF6C3BC0, 0370 (r1 DELL PE_SC3 1 DELL 1) (XEN) ACPI: TCPA CF6C3F34, 0064 (r2 DELL PE_SC3 1 DELL 1) (XEN) ACPI: SSDT CF6C7000, 41E4 (r1 INTEL PPM RCM 80000001 INTL 20061109) (XEN) Domain heap initialised (XEN) Processor #16 7:10 APIC version 21 (XEN) Processor #0 7:10 APIC version 21 (XEN) Processor #18 7:10 APIC version 21 (XEN) Processor #2 7:10 APIC version 21 (XEN) Processor #20 7:10 APIC version 21 (XEN) Processor #4 7:10 APIC version 21 (XEN) Processor #22 7:10 APIC version 21 (XEN) Processor #6 7:10 APIC version 21 (XEN) Processor #17 7:10 APIC version 21 (XEN) Processor #1 7:10 APIC version 21 (XEN) Processor #19 7:10 APIC version 21 (XEN) Processor #3 7:10 APIC version 21 (XEN) Processor #21 7:10 APIC version 21 (XEN) Processor #5 7:10 APIC version 21 (XEN) Processor #23 7:10 APIC version 21 (XEN) Processor #7 7:10 APIC version 21 (XEN) IOAPIC[0]: apic_id 0, version 32, address 0xfec00000, GSI 0-23 (XEN) IOAPIC[1]: apic_id 1, version 32, address 0xfec80000, GSI 32-55 (XEN) Enabling APIC mode: Phys.
