iommu/amd: Implements irq_set_vcpu_affinity() hook to setup vapic mode for pass-through devices

2016-09-05T10:41:46Z

This patch implements irq_set_vcpu_affinity() function to set up interrupt remapping table entry with vapic mode for pass-through devices. In case requirements for vapic mode are not met, it falls back to set up the IRTE in legacy mode. Signed-off-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel

iommu/amd: Introduce amd_iommu_update_ga()

2016-09-05T10:41:46Z

Introduces a new IOMMU API, amd_iommu_update_ga(), which allows KVM (SVM) to update existing posted interrupt IOMMU IRTE when load/unload vcpu. Signed-off-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel

iommu/amd: Adding GALOG interrupt handler

2016-09-05T10:41:46Z

This patch adds AMD IOMMU guest virtual APIC log (GALOG) handler. When IOMMU hardware receives an interrupt targeting a blocking vcpu, it creates an entry in the GALOG, and generates an interrupt to notify the AMD IOMMU driver. At this point, the driver processes the log entry, and notify the SVM driver via the registered iommu_ga_log_notifier function. Signed-off-by: Suravee Suthikulpanit Signed-off-by: Joerg Roedel

iommu/amd: Moving PPR fault flags macros definitions

2014-07-09T14:02:41Z

Any kernel source registering the invalid PPR calback may include the header file with PPR fault flags macros definitions. Thus we move them to include/linux/amd-iommu.h Signed-off-by: Alexey Skidanov Signed-off-by: Oded Gabbay Signed-off-by: Joerg Roedel

iommu/amd: Split amd_iommu_init function

2012-03-01T15:14:48Z

The hardware-initializtion part of the AMD IOMMU driver is split out into a seperate function. This function can now be called either from amd_iommu_init() itself or any other place if the hardware needs to be ready earlier. This will be used to implement interrupt remapping for AMD.

iommu/amd: Add invalidate-context call-back

2011-12-15T10:15:39Z

This call-back is invoked when the task that is bound to a pasid is about to exit. The driver can use it to shutdown all context related to that context in a safe way. Signed-off-by: Joerg Roedel

iommu/amd: Add amd_iommu_device_info() function

2011-12-15T10:15:29Z

This function can be used to find out which features necessary for IOMMUv2 usage are available on a given device. Signed-off-by: Joerg Roedel

iommu/amd: Add invalid_ppr callback

2011-12-14T11:09:39Z

This callback can be used to change the PRI response code sent to a device when a PPR fault fails. Signed-off-by: Joerg Roedel

iommu/amd: Add routines to bind/unbind a pasid

2011-12-12T14:34:42Z

This patch adds routines to bind a specific process address-space to a given PASID. Signed-off-by: Joerg Roedel

iommu/amd: Implement device aquisition code for IOMMUv2

2011-12-12T14:32:51Z

This patch adds the amd_iommu_init_device() and amd_iommu_free_device() functions which make a device and the IOMMU ready for IOMMUv2 usage. Signed-off-by: Joerg Roedel
