1-1 mapping of devices without VT-d

Passera, Pablo R — 2008-12-01T15:34:36

Hi everyone, I want to assign a PCI device directly to a VM (PCI passthrough) in a machine that does not have VT-d. I found something related with this in a presentation done at the 2008 KVM Forum called 1-1 mapping and a patch for this at http://thread.gmane.org/gmane.comp.emulators.kvm.devel/18722/focus=18753. I am wondering if this is included or are there plans to include it in the latest KVM version? Thanks in advance, Pablo Pássera -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo< at >vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[PATCH 3/3] KVM-userspace: generate a SRAT table to describe the guests NUMA topology

Andre Przywara — 2008-11-27T22:28:16

According to the number of nodes passed in the CMOS RAM (offset 0x3e) the BIOS code generates a SRAT (System Resources Affinity Table) to describe which (V)CPU and which part of memory is assigned to a certain node. This will then be read and hopefully honored by the guest OS. Signed-off-by: Andre Przywara amd.com>

[PATCH 2/3] KVM-userspace: allocate guest resources from different host nodes

Andre Przywara — 2008-11-27T22:27:04

According to the host node map given on the command line the VCPUs are pinned to the respective node (allowing at least scheduling between the cores belonging to this node). The mmap'ed guest memory will be bound to the correct host nodes (this will of course not take effect until the memory actually faults in). Since libnuma is not that widespread (in default installations), I chose 'enable via configure' by now: --enable-numa will compile the parts in. Signed-off-by: Andre Przywara amd.com>

[PATCH 0/3] KVM-userspace: add NUMA support for guests

Andre Przywara — 2008-11-27T22:23:21

Hi, this patch series introduces multiple NUMA nodes support within KVM guests. This will improve the performance of guests which are bigger than one node (number of VCPUs and/or amount of memory) and also allows better balancing by taking better usage of each node's memory. It also improves the one node case by pinning a guest to this node and avoiding access of remote memory from one VCPU. The user (or better: management application) specifies the host nodes the guest should use: -nodes 2,3 would create a two node guest mapped to node 2 and 3 on the host. These numbers are handed over to libnuma: VCPUs are pinned to the nodes and the allocated guest memory is bound to it's respective node. Since libnuma seems not to be installed everywhere, the user has to enable this via configure --enable-numa In the BIOS code an ACPI SRAT table was added, which describes the NUMA topology to the guest. The number of nodes is communicated via the CMOS RAM (offset 0x3E). If someone thinks of this as a bad idea, tell m

[PATCH 0/9] Factor VT-d KVM functions into a generic API

Joerg Roedel — 2008-11-27T15:40:45

Hi, this patch series makes the current KVM device passthrough code generic enough so that other IOMMU implementation can also plug into this code. It works by factoring the functions Vt-d code exports to KVM into a generic interface which allows different backends. This a basic implementation of a generic interface. It can and should be improved later to support more types of hardware IOMMUs then VT-d and AMD IOMMU. Since I have no VT-d hardware available these patches are only compile tested for now. Please review, comment and test these patches.

Han, Weidong — 2008-11-27T13:49:04

In order to support multiple device assignment for KVM, this patch does following main changes: - extend dmar_domain to own multiple devices from different iommus, use a bitmap of iommus to replace iommu pointer in dmar_domain. - implement independent low level functions for kvm, then won't impact native VT-d. - "SAGAW" capability may be different across iommus, that's to say the VT-d page table levels may be different among iommus. This patch uses a defaut agaw, and skip top levels of page tables for iommus which have smaller agaw than default. - rename the APIs for kvm VT-d, make it more readable.
