[Xen-users] SR-IOV error "not enough MMIO resources for SR-IOV"
Hi to all, I''m trying to enable SR-IOV on an Intel 82576. I''ve enabled IOMMU in bios and I''ve also added iommu=pv to xen command line but when I try to load the igb driver with max_vfs=4 I cannot enable SR-IOV. I''m testing SUSE 11 SP1 with latest patches and the motherboard is a supermicro H8DGU-LN4F+ with a couple of AMD 6168. here is a part of the dmesg output [ 7.382215] igb 0000:08:00.1: Intel(R) Gigabit Ethernet Network Connection [ 7.382294] igb 0000:08:00.1: eth0: (PCIe:2.5Gb/s:Width x4) 00:25:90:19:57:cf [ 7.382425] igb 0000:08:00.1: eth0: PBA No: ffffff-0ff [ 7.382473] igb 0000:08:00.1: Using MSI-X interrupts. 4 rx queue(s), 4 tx queue(s) [ 7.382846] igb 0000:02:00.0: power state changed by ACPI to D0 [ 7.382994] igb 0000:02:00.0: power state changed by ACPI to D0 [ 7.383057] igb 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 7.383183] igb 0000:02:00.0: setting latency timer to 64 [ 7.383537] igb 0000:02:00.0: not enough MMIO resources for SR-IOV [ 7.383752] igb 0000:02:00.0: irq 573 (253) for MSI/MSI-X [ 7.383790] igb 0000:02:00.0: irq 572 (252) for MSI/MSI-X [ 7.383827] igb 0000:02:00.0: irq 571 (251) for MSI/MSI-X [ 7.383866] igb 0000:02:00.0: irq 570 (250) for MSI/MSI-X [ 7.383903] igb 0000:02:00.0: irq 569 (249) for MSI/MSI-X [ 7.383940] igb 0000:02:00.0: irq 568 (248) for MSI/MSI-X [ 7.384015] igb 0000:02:00.0: irq 567 (247) for MSI/MSI-X [ 7.384064] igb 0000:02:00.0: irq 566 (246) for MSI/MSI-X [ 7.384113] igb 0000:02:00.0: irq 565 (245) for MSI/MSI-X Could anyone give me some hints? ...do you think it''s a bios issue or something else?
