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>
