[Xen-devel] Intel processor model 30 for P6 class family is not supported
We have installed Xen version 3.3.1 on CentOS 5.2 32-bit, which runs on a testbed that has the Intel Jasper Forest processor. When we perform xm dmesg, we get the following message: (XEN) xenoprof: Initialization failed. Intel processor model 30 for P6 class family is not supported Since this processor has not yet been released, this may explain the aforementioned message. But we would like to know whether this has any negative impact on Xen itself(performance, vt-d, etc.) if Xen detects an unknown processor model like the Jasper Forest. Or is it just informational? Any insight on this is appreciated, Daniel ------------------------------------------- The following is the complete dmesg output: (XEN) ERROR: 16550-compatible serial UART not present (XEN) Bad console= option ''com1'' __ __ _____ _____ _ \ \/ /___ _ __ |___ / |___ / / | \ // _ \ ''_ \ |_ \ |_ \ | | / \ __/ | | | ___) | ___) || | /_/\_\___|_| |_| |____(_)____(_)_| (XEN) Xen version 3.3.1 (root@) (gcc version 4.1.2 20071124 (Red Hat 4.1.2-42)) Wed May 6 06:06:21 EDT 2009 (XEN) Latest ChangeSet: 8417ddc981b4.d3199736facb (3.3.1 5.1.0.354.18669) (XEN) Command line: acpi=force apic=on vtd=1 iommu=1 com1=115200,8n1 console=com1 (XEN) Video information: (XEN) VGA is text mode 80x25, font 8x16 (XEN) VBE/DDC methods: none; EDID transfer time: 0 seconds (XEN) EDID info not retrieved because no DDC retrieval method detected (XEN) Disc information: (XEN) Found 2 MBR signatures (XEN) Found 2 EDD information structures (XEN) Xen-e820 RAM map: (XEN) 0000000000000000 - 000000000009ec00 (usable) (XEN) 000000000009ec00 - 00000000000a0000 (reserved) (XEN) 00000000000e0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 000000003f3c5000 (usable) (XEN) 000000003f3c5000 - 000000003f3eb000 (ACPI NVS) (XEN) 000000003f3eb000 - 000000003f42b000 (reserved) (XEN) 000000003f42b000 - 000000003f435000 (ACPI data) (XEN) 000000003f435000 - 000000003f43f000 (ACPI NVS) (XEN) 000000003f43f000 - 000000003f464000 (reserved) (XEN) 000000003f464000 - 000000003f667000 (ACPI NVS) (XEN) 000000003f667000 - 000000003f800000 (usable) (XEN) 000000003f800000 - 0000000040000000 (reserved) (XEN) 00000000c0000000 - 00000000d0000000 (reserved) (XEN) 00000000fed1c000 - 00000000fed20000 (reserved) (XEN) 00000000ff000000 - 0000000100000000 (reserved) (XEN) System RAM: 1012MB (1037296kB) (XEN) ACPI: RSDP 000F03C0, 0024 (r2 ALASKA) (XEN) ACPI: XSDT 3F433E18, 0044 (r1 ALASKA A M I 6222004 MSFT 10013) (XEN) ACPI: FACP 3F432D98, 00F4 (r4 ALASKA A M I 6222004 MSFT 10013) (XEN) ACPI: DSDT 3F42B018, 6201 (r1 ALASKA A M I 0 INTL 20051117) (XEN) ACPI: FACS 3F43CD40, 0040 (XEN) ACPI: APIC 3F432F18, 00CC (r2 ALASKA A M I 6222004 MSFT 10013) (XEN) ACPI: MCFG 3F434F18, 003C (r1 A M I OEMMCFG 6222004 MSFT 97) (XEN) ACPI: HPET 3F434E98, 0038 (r1 ALASKA A M I 6222004 AMI. 3) (XEN) Xen heap: 14MB (14700kB) (XEN) Domain heap initialised (XEN) Processor #0 7:14 APIC version 21 (XEN) Processor #1 7:14 APIC version 21 (XEN) Processor #2 7:14 APIC version 21 (XEN) Processor #3 7:14 APIC version 21 (XEN) Processor #4 7:14 APIC version 21 (XEN) Processor #5 7:14 APIC version 21 (XEN) Processor #6 7:14 APIC version 21 (XEN) Processor #7 7:14 APIC version 21 (XEN) IOAPIC[0]: apic_id 0, version 32, address 0xfec00000, GSI 0-23 (XEN) Enabling APIC mode: Flat.

RE: [Xen-devel] Intel processor model 30 for P6 class family is not supported
Thanks for your prompt response. But we are still concerned about the statement "Initialization failed". Could you elaborate on that a little bit more as to what kind of initialization has failed? If it''s just informational, then "Initialization failed" can be quite an intimidating statement to be printed out. Second question would be whether you know when Jasper Forest or model 30 will be recognized by Xen. Any help is again greatly appreciated, Daniel ________________________________________ From: Keir Fraser [keir.fraser@eu.citrix.com] Sent: Wednesday, June 03, 2009 1:52 AM To: Nguyen, Daniel; xen-devel@lists.xensource.com Subject: Re: [Xen-devel] Intel processor model 30 for P6 class family is not supported On 03/06/2009 01:51, "Nguyen, Daniel" <Daniel.Nguyen@lsi.com> wrote:> We have installed Xen version 3.3.1 on CentOS 5.2 32-bit, which runs on a > testbed that has the Intel Jasper Forest processor.

Re: [Xen-devel] Intel processor model 30 for P6 class family is not supported
It means you can''t run xenoprof (basically that''s oprofile ported for Xen). It''s only useful for system profiling; it''s not really a user feature. -- Keir On 03/06/2009 21:02, "Nguyen, Daniel" <Daniel.Nguyen@lsi.com> wrote:> Thanks for your prompt response. > > But we are still concerned about the statement "Initialization failed".
