http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1607 Summary: VT-d on Dell Optiplex 380 Product: Xen Version: unstable Platform: Other OS/Version: n/a Status: NEW Severity: normal Priority: P2 Component: Hardware Support AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx ReportedBy: zhalassy@xxxxxxxxxx Dell Optiplex 380 has a BIOS option, "Enable Intel® VT for Direct I/O", this is turned on, then i removed the power cable for ~40 secs as suggested on the wiki, turned on again, and checked the BIOS it's still on. Xen 3.4 crashes with iommu=1, Xen 4.0 does not, but claims IOMMU Unsupported. The Motherboard has the Intel G41 Express chipset, and has a Core2 E7500. Does this one lack the support for VT-d, or is there some kind of workaround? This is the output for xen 4.0: __ __ _ _ ___ ___ \ \/ /___ _ __ | || | / _ \ / _ \ \ // _ \ '_ \ | || |_| | | | | | | / \ __/ | | | |__ _| |_| | |_| | /_/\_\___|_| |_| |_|(_)___(_)___/ (XEN) Xen version 4.0.0 (root@xxxxxxxxxxxxxxxx) (gcc version 4.3.4 (Gentoo 4.3.4 p1.1, pie-10.1.5) ) Mon May 3 09:51:58 CEST 2010 (XEN) Latest ChangeSet: unavailable (XEN) Command line: iommu=1,verbose (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 - 000000000009fc00 (usable) (XEN) 00000000000f0000 - 0000000000100000 (reserved) (XEN) 0000000000100000 - 00000000cda08c00 (usable) (XEN) 00000000cda08c00 - 00000000cda5cc00 (ACPI NVS) (XEN) 00000000cda5cc00 - 00000000cda5ec00 (ACPI data) (XEN) 00000000cda5ec00 - 00000000d0000000 (reserved) (XEN) 00000000e0000000 - 00000000f0000000 (reserved) (XEN) 00000000fec00000 - 00000000fed00400 (reserved) (XEN) 00000000fed20000 - 00000000feda0000 (reserved) (XEN) 00000000fee00000 - 00000000fef00000 (reserved) (XEN) 00000000ffb00000 - 0000000100000000 (reserved) (XEN) 0000000100000000 - 000000012c000000 (usable) (XEN) ACPI: RSDP 000FEBF0, 0024 (r2 DELL ) (XEN) ACPI: XSDT 000FCE80, 0064 (r1 DELL B10K 15 ASL 61) (XEN) ACPI: FACP 000FCFA8, 00F4 (r3 DELL B10K 15 ASL 61) (XEN) ACPI: DSDT FFE9503F, 45F6 (r1 DELL dt_ex 1000 INTL 20050624) (XEN) ACPI: FACS CDA08C00, 0040 (XEN) ACPI: SSDT FFE99756, 00AC (r1 DELL st_ex 1000 INTL 20050624) (XEN) ACPI: APIC 000FD09C, 0092 (r1 DELL B10K 15 ASL 61) (XEN) ACPI: BOOT 000FD12E, 0028 (r1 DELL B10K 15 ASL 61) (XEN) ACPI: MCFG 000FD156, 003E (r1 DELL B10K 15 ASL 61) (XEN) ACPI: HPET 000FD194, 0038 (r1 DELL B10K 15 ASL 61) (XEN) ACPI: TCPA 000FD3F0, 0032 (r1 DELL B10K 15 ASL 61) (XEN) ACPI: DMAR 000FD422, 00F8 (r1 DELL B10K 15 ASL 61) (XEN) System RAM: 3967MB (4062716kB) (XEN) Domain heap initialised (XEN) Processor #0 7:7 APIC version 20 (XEN) Processor #1 7:7 APIC version 20 (XEN) IOAPIC[0]: apic_id 8, version 32, address 0xfec00000, GSI 0-23 (XEN) Enabling APIC mode: Flat.
