2012-09-28iommu/amd: Add IRTE invalidation routineJoerg Roedel1-0/+3
Add routine to invalidate the IOMMU cache for interupt translations. Also include the IRTE caches when flushing all IOMMU caches. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-09-28iommu/amd: Allocate data structures to keep track of irq remapping tablesJoerg Roedel1-0/+9
To easily map device ids to interrupt remapping table entries a new lookup table is necessary. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-09-28iommu/amd: Add slab-cache for irq remapping tablesJoerg Roedel1-0/+9
The irq remapping tables for the AMD IOMMU need to be aligned on a 128 byte boundary. Create a seperate slab-cache to guarantee this alignment. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-09-28iommu/amd: Keep track of HPET and IOAPIC device idsJoerg Roedel1-0/+34
The IVRS ACPI table provides information about the IOAPICs and the HPETs available in the system and which PCI device ID they use in transactions. Save that information for later usage in interrupt remapping. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Reviewed-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2012-09-18iommu/amd: Fix some typosFrank Arnold1-2/+2
Fix some typos in comments and user-visible messages. No functional changes. Signed-off-by: Frank Arnold <frank.arnold@amd.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-07-17iommu/amd: Split out PCI related parts of IOMMU initializationJoerg Roedel1-2/+3
For interrupt remapping the relevant IOMMU initialization needs to run earlier at boot when the PCI subsystem is not yet initialized. To support that this patch splits the parts of IOMMU initialization which need PCI accesses out of the initial setup path so that this can be done later. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-07-17iommu/amd: Fix sparse warningsJoerg Roedel1-1/+7
A few sparse warnings fire in drivers/iommu/amd_iommu_init.c. Fix most of them with this patch. Also fix the sparse warnings in drivers/iommu/irq_remapping.c while at it. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2012-07-02iommu/amd: fix type bug in flush codeDan Carpenter1-1/+1
write_file_bool() modifies 32 bits of data, so "amd_iommu_unmap_flush" needs to be 32 bits as well or we'll corrupt memory. Fortunately it looks like the data is aligned with a gap after the declaration so this is harmless in production.

2012-06-04iommu/amd: Cache pdev pointer to root-bridgeJoerg Roedel1-0/+3
At some point pci_get_bus_and_slot started to enable interrupts. Since this function is used in the amd_iommu_resume path it will enable interrupts on resume which causes a warning. The fix will use a cached pointer to the root-bridge to re-enable the IOMMU in case the BIOS is broken. Cc: stable@vger.kernel.org Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-22iommu/amd: Set IOTLB invalidation timeoutJoerg Roedel1-0/+10
To protect the command buffer from hanging when a device does not respond to an IOTLB invalidation, set a timeout of 1s for outstanding IOTLB invalidations. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add device errata handlingJoerg Roedel1-0/+1
Add infrastructure for errata-handling and handle two known erratas in the IOMMUv2 code. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add function to get IOMMUv2 domain for pdevJoerg Roedel1-0/+4
The AMD IOMMUv2 driver needs to get the IOMMUv2 domain associated with a particular device. This patch adds a function to get this information. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement function to send PPR completionsJoerg Roedel1-0/+6
To send completions for PPR requests this patch adds a function which can be used by the IOMMUv2 driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement functions to manage GCR3 tableJoerg Roedel1-0/+1
This patch adds functions necessary to set and clear the GCR3 values associated with a particular PASID in an IOMMUv2 domain. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement IOMMUv2 TLB flushing routinesJoerg Roedel1-0/+1
The functions added with this patch allow to manage the IOMMU and the device TLBs for all devices in an IOMMUv2 domain. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add support for IOMMUv2 domain modeJoerg Roedel1-0/+27
This patch adds support for protection domains that implement two-level paging for devices. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement notifier for PPR faultsJoerg Roedel1-1/+33
Add a notifer at which a module can attach to get informed about incoming PPR faults. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Put IOMMUv2 capable devices in pt_domainJoerg Roedel1-0/+4
If the device starts to use IOMMUv2 features the dma handles need to stay valid. The only sane way to do this is to use a identity mapping for the device and not translate it by the iommu. This is implemented with this patch. Since this lifts the device-isolation there is also a new kernel parameter which allows to disable that feature. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add iommuv2 flag to struct amd_iommuJoerg Roedel1-0/+5
In mixed IOMMU setups this flag inidicates whether an IOMMU supports the v2 features or not. This patch also adds a global flag together with a function to query that flag from other code. The flag shows if at least one IOMMUv2 is in the system. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Enable GT mode when supported by IOMMUJoerg Roedel1-0/+1
This feature needs to be enabled before IOMMUv2 DTEs can be set up. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Setup PPR log when supported by IOMMUJoerg Roedel1-0/+14

2011-12-12iommu/amd: Get the maximum number of PASIDs supportedJoerg Roedel1-0/+6
Read the number of PASIDs supported by each IOMMU in the system and take the smallest number as the maximum value supported by the IOMMU driver. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
