2016-09-05iommu/amd: Implements irq_set_vcpu_affinity() hook to setup vapic mode for ↵Suravee Suthikulpanit1-0/+14
pass-through devices 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.

2016-09-05iommu/amd: Introduce amd_iommu_update_ga()Suravee Suthikulpanit1-0/+9
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 <suravee.suthikulpanit@amd.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2016-09-05iommu/amd: Adding GALOG interrupt handlerSuravee Suthikulpanit1-3/+17
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.

2014-07-09iommu/amd: Moving PPR fault flags macros definitionsAlexey Skidanov1-0/+7
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 <Alexey.Skidanov@amd.com> Signed-off-by: Oded Gabbay <oded.gabbay@amd.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
2012-03-01iommu/amd: Split amd_iommu_init functionJoerg Roedel1-1/+1
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.

2011-12-15iommu/amd: Add invalidate-context call-backJoerg Roedel1-0/+17
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 <joerg.roedel@amd.com>
2011-12-15iommu/amd: Add amd_iommu_device_info() functionJoerg Roedel1-0/+26
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 <joerg.roedel@amd.com>
2011-12-14iommu/amd: Add invalid_ppr callbackJoerg Roedel1-3/+31
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 <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add routines to bind/unbind a pasidJoerg Roedel1-0/+26
This patch adds routines to bind a specific process address-space to a given PASID. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-12-12iommu/amd: Implement device aquisition code for IOMMUv2Joerg Roedel1-1/+22
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 <joerg.roedel@amd.com>
2011-12-12iommu/amd: Add device errata handlingJoerg Roedel1-0/+18
Add infrastructure for errata-handling and handle two known erratas in the IOMMUv2 code. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2011-06-21iommu/amd: Move missing parts to drivers/iommuJoerg Roedel1-0/+35
A few parts of the driver were missing in drivers/iommu. Move them there to have the complete driver in that directory. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
