2009-01-03introcude linux/iommu.h for an iommu apiJoerg Roedel
This patch introduces the API to abstract the exported VT-d functions for KVM into a generic API. This way the AMD IOMMU implementation can plug into this API later. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03KVM: rename vtd.c to iommu.cJoerg Roedel
Impact: file renamed The code in the vtd.c file can be reused for other IOMMUs as well. So rename it to make it clear that it handle more than VT-d. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Deassign device in kvm_free_assgined_deviceWeidong Han
In kvm_iommu_unmap_memslots(), assigned_dev_head is already empty. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03KVM: support device deassignmentWeidong Han
Support device deassignment, it can be used in device hotplug. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03KVM: use the new intel iommu APIsWeidong Han
intel iommu APIs are updated, use the new APIs. In addition, change kvm_iommu_map_guest() to just create the domain, let kvm_iommu_assign_device() assign device. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Check agaw is sufficient for mapped memoryWeidong Han
When domain is related to multiple iommus, need to check if the minimum agaw is sufficient for the mapped memory Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Change intel iommu APIs of virtual machine domainWeidong Han
These APIs are used by KVM to use VT-d Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Change domain_context_mapping_one for virtual machine domainWeidong Han
vm_domid won't be set in context, find available domain id for a device from its iommu. For a virtual machine domain, a default agaw will be set, and skip top levels of page tables for iommu which has less agaw than default. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Allocation and free functions of virtual machine domainWeidong Han
virtual machine domain is different from native DMA-API domain, implement separate allocation and free functions for virtual machine domain. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Add domain_flush_cacheWeidong Han
Because virtual machine domain may have multiple devices from different iommus, it cannot use __iommu_flush_cache. In some common low level functions, use domain_flush_cache instead of __iommu_flush_cache. On the other hand, in some functions, iommu can is specified or domain cannot be got, still use __iommu_flush_cache Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Add/remove domain device info for virtual machine domainWeidong Han
Add iommu reference count in domain, and add a lock to protect iommu setting including iommu_bmp, iommu_count and iommu_coherency. virtual machine domain may have multiple devices from different iommus, so it needs to do more things when add/remove domain device info. Thus implement separate these functions for virtual machine domain. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Add domain flag DOMAIN_FLAG_VIRTUAL_MACHINEWeidong Han
Add this flag for VT-d used in virtual machine, like KVM. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03iommu coherencyWeidong Han
In dmar_domain, more than one iommus may be included in iommu_bmp. Due to "Coherency" capability may be different across iommus, set this variable to indicate iommu access is coherent or not. Only when all related iommus in a dmar_domain are all coherent, iommu access of this domain is coherent. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03calculate agaw for each iommuWeidong Han
"SAGAW" capability may be different across iommus. Use a default agaw, but if default agaw is not supported in some iommus, choose a less supported agaw. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03iommu bitmap instead of iommu pointer in dmar_domainWeidong Han
In order to support assigning multiple devices from different iommus to a domain, iommu bitmap is used to keep all iommus the domain are related to. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Get iommu from g_iommus for deferred flushWeidong Han
deferred_flush[] uses the iommu seq_id to index, so its iommu is fixed and can get it from g_iommus. Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03Add global iommu listWeidong Han

It's random number after the domain is allocated by kmem_cache_alloc Signed-off-by: Weidong Han <weidong.han@intel.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2009-01-03V4L/DVB (10173): Missing v4l2_prio_close in radio_releaseUdo Steinberg
The radio_release function of the BTTV driver is missing a call to v4l2_prio_close. As a result, after the radio device has been opened at least once (e.g., by HAL during bootup), v4l2_priority will never drop below V4L2_PRIORITY_INTERACTIVE again. With the following patch against 2.6.28, applications that run with V4L2_PRIORITY_BACKGROUND are able to open devices again. Previous Linux versions are affected as well.

2009-01-03V4L/DVB (10171): Use usb_set_intfdataJulia Lawall
This code had calls to both usb_set_intfdata and dev_set_drvdata, doing the same thing.

2009-01-03VT-d: fix segment number being ignored when searching DRHDYu Zhao
On platforms with multiple PCI segments, any of the segments can have a DRHD with INCLUDE_PCI_ALL flag. So need to check the DRHD's segment number against the PCI device's when searching its DRHD.

2009-01-03intel-iommu: remove some unused struct intel_iommu fieldsMark McLoughlin
The seg, saved_msg and sysdev fields appear to be unused since before the code was first merged. linux/msi.h is not needed in linux/intel-iommu.h anymore since there is no longer a reference to struct msi_msg. The MSI code in drivers/pci/intel-iommu.c still has linux/msi.h included via linux/dmar.h. linux/sysdev.h isn't needed because there is no reference to struct sys_device.

2009-01-02sparc: unify openprom.hSam Ravnborg
After the preparational steps the unification was simple. The linux_prom_pci_registers definition did not look like it could be unified at first look since the structure is assigned using prop_getproperty() / of_get_property() so the structure is assumed to come direct form the prom. The LINUX_OPPROM_MAGIC was kept even if it is not used by the kernel on the assumption that userspace may require it. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
